2021 MICHIGAN CHILD SUPPORT FORMULA MANUAL

1. BACKGROUND
1.01 Statewide Child Support Guideline
1.01(A) Michigan’s child support guideline (also known as the “formula”) consists of this
manual and its most current supplement.
1.01(B) Except as otherwise permitted by MCL 552.605
, courts must order child support in the
amount determined by applying this formula. Unless rebutted by facts in a specific case,
the law presumes that this formula (or “guideline”) sets appropriate levels of support.
1.01(C) The periodically updated supplement to this manual contains the most current economic
figures and materials related to the formula.
1.01(D) To verify that you have the most current materials, or to find additional guidance on
using this manual, please check the Michigan Child Support Formula’s official website
at http://courts.mi.gov/mcsf
.
1.02 Support
1.02(A) A child support obligation includes payment for the general care and needs of a child
(base support calculated in §3.02 – §3.03), medical support (§3.04– §3.05), and child
care expenses (§3.06).
1.02(B) Support amounts should be rounded to the nearest whole dollar.
1.02(C) To avoid recalculating support each time the number of children for whom support is
paid changes, support provisions for multiple children must include tiered amounts for
fewer children. When a support order is for several children, unless it specifies an
amount for a particular child, each child’s share of the support obligation is that child’s
per capita share of the ordered amount.
1.02(D) The formula establishes the support obligations for both parents:
(1) A paying parent’s contribution for a child’s expenses will be established in a
support order.
(2) A recipient-parent is presumed to contribute directly to a child’s support.
1.03 Citation
1.03(A) References to this manual should include the manual year cited, and the specific
provision being referenced. The manual’s title may be abbreviated as “MCSF.” For
example, this subsection could be cited as “2021 MCSF 1.03(A).”
1.03(B) References to material contained in the supplement to this manual should specify the
year of the supplement cited and the provision being referenced. The supplement may
be abbreviated as “MCSF-S.”
1.04 Deviation from the Formula
1.04(A) When applying the formula would lead to an unjust or inappropriate result, the court
may exercise its discretion, and, on a case-by-case basis, deviate from the formula and
determine a more appropriate support amount. Deviations cannot be based solely on
disagreement with the policies embodied in the formula.
2021 MICHIGAN CHILD SUPPORT FORMULA MANUAL
2
See: MCL 552.605
, Ghidotti v Barber, 459 Mich 189 (1998), and Burba v Burba, 461 Mich
637 (2000).
1.04(B) When a court decides to deviate, it should still follow the formula except for the
provisions that create an unjust or inappropriate result in that case.
(1) When entering an order that deviates from the child support formula, the court
must record (a) its reasons for finding that the formula would produce an unjust or
inappropriate result, as well as (b) the information required by MCL 552.605(2)
.
Burba v Burba, 461 Mich 637, 644-45 (2000).
(2) Friend of the court recommendations that deviate from the formula must comply
with the requirements in MCL 552.505(1)(h)
.
1.04(C) Agreements to Deviate
MCL 552.605(3)
permits the court to enter orders that deviate from the formula based
on an agreement of the parties, so long as the court also satisfies all the requirements of
MCL 552.605(2).
1.04(D) In exercising its discretion to deviate, the court may consider any factor that it
determines is relevant.
1.04(E) Deviation Factors
Strict application of the formula may produce an unjust or inappropriate result in a case
when any of the following situations occur:
(1) The child has special needs.
(2) The child has extraordinary educational expenses.
(3) A parent is a minor.
(4) The child’s residence income is below the threshold to qualify for public
assistance, and at least one parent has sufficient income to pay additional support
that will raise the child’s standard of living above the public assistance threshold.
(5) A parent has a reduction in the income available to support a child due to
extraordinary levels of jointly accumulated debt.
(6) The court awards property in lieu of support for the benefit of the child (§4.04).
(7) A parent has incurred, or is likely to incur, extraordinary medical expenses for
either that parent or a dependent.
(8) A parent receives bonus income in varying amounts or at irregular intervals.
(9) Someone other than the parent can supply reasonable and appropriate health care
coverage.
(10) A parent provides substantially all the support for a stepchild, and the stepchild’s
parents earn no income and are unable to earn income.
(11) A child earns an extraordinary income.
(12) The court orders a parent to pay taxes, mortgage installments, home insurance
premiums, telephone or utility bills, etc., before entry of a final judgment or order.
2021 MICHIGAN CHILD SUPPORT FORMULA MANUAL
3
(13) A parent must pay significant amounts of restitution, fines, fees, or costs
associated with that parent’s conviction or incarceration for a crime other than
those related to failing to support children, or a crime against a child in the current
case or that child’s sibling, other parent, or custodian.
(14) A parent makes payments to a bankruptcy plan or has debt discharged, when
either significantly impacts the monies that parent has available to pay support.
(15) A parent provides a substantial amount of a child’s day-time care and directly
contributes toward a significantly greater share of the child’s costs than those
reflected by the overnights used to calculate the offset for parental time.
(16) A child in the custody of a nonparent-recipient spends a significant number of
overnights with the payer that causes a significant savings in the nonparent-
custodian’s expenses.
(17) The court ordered nonmodifiable spousal support paid between the parents before
October 2004.
(18) When a parent’s share of net child care expenses exceeds 50 percent of that
parent’s base support obligation calculated under §3.02 before applying the
parental time offset.
(19) When the amount calculated does not exceed $20, and the administrative cost to
enforce and process payments outweighs the benefit of the minimal amounts.
(20) Any other factor the court deems relevant to the best interests of a child.
2021 MICHIGAN CHILD SUPPORT FORMULA MANUAL

2. DETERMINING INCOME
The first step in figuring each parent’s support obligation is to determine both parents’
individual incomes.
2.01 Income
2.01(A) The term “net income” means all income minus the deductions and adjustments
permitted by this manual. A parent’s “net income” used to calculate support will not be
the same as that person’s take home pay, net taxable income, or similar terms that
describe income for other purposes.
2.01(B) The objective of determining net income is to establish, as accurately as possible, how
much money a parent should have available for support. All relevant aspects of a
parent’s financial status are open for consideration when determining support.
2.01(C) Income includes, but is not limited to, the following:
(1) Wages, overtime pay, commissions, bonuses, or other monies from all employers
or as a result of any employment (usually, as reported in the Medicare, wages, and
tips section of the parent’s W-2).
(2) Earnings generated from a business, partnership, contract, self-employment, or
other similar arrangement, or from rentals. §2.01(E).
(a) Income (or losses) from a corporation should be carefully examined to
determine the extent to which they were historically passed on to the parent
or used merely as a tax strategy.
(3) Distributed profits or payments from profit-sharing, a pension or retirement, an
insurance contract, an annuity, trust fund, deferred compensation, retirement
account, social security, unemployment compensation, supplemental
unemployment benefits, disability insurance or benefits, or worker’s
compensation.
(a) Consider insurance or other similar payments received as compensation for
lost earnings, but do not count payments that compensate for actual medical
bills or for property loss or damage.
(b) If a retired parent receives payments from an IRA, defined contribution, or
deferred compensation plan, income does not include contributions to that
account that were previously considered as the parent’s income used to
calculate an earlier child support obligation for a child in this case.
(4) Military specialty pay, allowance for quarters and rations, housing, veterans’
administration benefits, G.I. benefits (other than education allotment), or drill pay.
(a) If the servicemember receives housing pay and supports another home (i.e.
second residence), housing pay is not considered income to the individual.
(5) Tips, gratuities, royalties, interest, dividends, fees, or gambling or lottery
winnings to the extent that they represent regular income or may be used to
generate regular income.
2021 MICHIGAN CHILD SUPPORT FORMULA MANUAL
6
(6) Net capital gains are included as income. When attributable to a single event or
year, or when cash may not be immediately available to the parent, consider them
to the extent they can be used to represent income over several years. To the
extent that a party proves that a portion of the capital gain was considered in the
property division of the judgment of divorce between the parties, that portion
should not be included as income.
(7) The standard (basic needs) portion of adoption subsidies for children in the case
under consideration (do not consider the medical needs and intensive rate portion
of the subsidy, nor the family support subsidy as income).
(8) Any money or income due or owed by another individual, source of income,
government, or other legal entity. Income considered should usually meet the
statutory definition found at MCL 552.602(o)
.
2.01(D) Income also includes the market value of perquisites (perks) received as goods,
services, or other noncash benefit for which the parent did not pay, if they reduce
personal expenses, and have significant value or are received regularly.
(1) Common forms of perquisites (perks) or goods and services received in-kind
include, but are not limited to: housing, meals, or room and board, personal use of
a company business vehicle or mileage reimbursement, including use between
home and primary worksite, and other goods or services.
(2) Perquisites (perks) do not include money paid by an employer for benefits like
tuition reimbursement, educational cost reimbursement, uniforms, and health
savings account (HSA) contributions.
2.01(E) Self-Employed Individuals, Business Owners, Executives, and Others
(1) Difficulty in determining income for self-employed individuals, business owners,
and others occurs for several reasons.
(a) These individuals often have types of income and expenses not frequently
encountered when determining income for most people.
(b) Taxation rules, business records, and forms associated with business
ownership and self-employment differ from those that apply to individuals
employed by others. Common business documents reflect policies unrelated
to an obligation to support one’s child.
(c) Due to the control that business owners or executives exercise over the form
and manner of their compensation, a parent, or a parent with the cooperation
of a business owner or executive, may be able to arrange compensation to
reduce the amount visible to others looking for common forms of income.
(2) In order to determine the monies that a parent has available for support, it may be
necessary to examine business tax returns, balance sheets, accounting or banking
records, and other business documents to identify any additional monies a parent
has available for support that were not included as personal income.
(3) Whether organized informally, or as a corporation, a partnership, a sole
proprietorship, or any other arrangement, these considerations apply to all forms
2021 MICHIGAN CHILD SUPPORT FORMULA MANUAL
7
of self-employment and business ownership, as well as to business executives and
others who may receive similar forms of compensation.
(4) For purposes of this subsection, income includes amounts that were not otherwise
included as income elsewhere in this chapter. Pay special attention to the
following forms of compensation:
(a) Distributed profits, profit sharing, officers’ fees and other compensation,
management or consulting fees, commissions, and bonuses.
(b) In-kind income or perquisites (§2.01(D)), gifts, free admission to
entertainment, or personal use of business property. (Determine the value
based on a fair market price, i.e., the price a person not affiliated with the
business would pay).
(c) Redirected income, or amounts treated by the business or company as if the
redirected amounts were something other than the parent’s income.
Amounts include, but are not limited to:
(i) Personal loans. Presume personal loans from a business are in fact
redirected income, unless all the following are true: (1) the parent
signed a contract or promissory note outlining the terms of the loan, (2)
the business maintains records showing the loan owed as a receivable,
(3) the parent makes installment payments and the present loan is paid
current, and (4) the interest earned and repayment rate appear to be a
reasonable business practice. Unless the presumption is overcome, a
parent’s income includes the difference between the amount the parent
repays and a repayment amount for a similar commercially available
unsecured personal loan.
(ii) Payments made to friends or relatives of the parent. If the business
cannot demonstrate that the payments are equivalent to a fair market
value payment for the work or services the friend or relative actually
performs, include any amount that exceeds the fair market value as the
parent’s income.
(d) Reduced or deferred income. Because a parent’s compensation can be
rearranged to hide income, determine whether unnecessary reductions in
salaries, fees, or distributed profits have occurred by comparing amounts
and rates to historical patterns.
(i) Unless the business can demonstrate legitimate reasons for a substantial
reduction in the percentage of distributed profits, use a three-year
average to determine the amount to include as a parent’s income.
(ii) Unless a business can demonstrate legitimate reasons for reductions (as
a percentage of gross business income) in salaries, bonuses,
management fees, or other amounts paid to a parent, use a three-year
average to determine the amount to include as a parent’s income.
(e) Deductions for Tax Purposes. For a variety of historical and policy reasons,
the government allows considerable deductions for business-related
expenses before taxes are calculated. Those same considerations are not
2021 MICHIGAN CHILD SUPPORT FORMULA MANUAL
8
always relevant to monies a parent should have available for child support.
Therefore, some deductions should be added back into a parent’s income
for purposes of determining child support, including:
(i) Rent paid by the business to the parent, if it is not counted as income on
that parent’s personal tax return.
(ii) Real estate depreciation should always be added back into a parent’s
income when calculating support.
(iii) Depreciation on home offices and personal vehicles should be added
back into a parent’s income. Accelerated depreciation should be added
back into a parent’s income except that any parent who uses accelerated
depreciation may deduct the value of the straight-line depreciation
amount if the parent proves what the straightline amounts would have
been.
(iv) Home office expenses, including rent, hazard insurance, utilities,
repairs, and maintenance.
(v) Entertainment expenses spent by the parent. Legitimate expenses for
customer’s entertainment are allowable as deductions.
(vi) Travel expense reimbursements, except where such expenses are
inherent in the nature of the business or occupation (e.g., a traveling
salesperson), and do not exceed the standard rates allowed by the state
of Michigan for employee travel.
(vii) Personal automobile repair and maintenance expenses.
2.01(F) Alimony and Spousal Support
(1) Income includes alimony/spousal support paid by someone who is not the other
parent in the case under consideration.
(2) Alimony/spousal support paid between the parents in the case under consideration
does not get deducted from its payer’s income.
2.01(G) Potential Income
When a parent is voluntarily unemployed or underemployed, or has an unexercised
ability to earn, income includes the potential income that parent could earn, subject to
that parent’s actual ability. Generally, do not consider incarceration as voluntary
unemployment.
(1) The amount of potential income imputed should be sufficient to bring that
parent’s income up to the level it would have been if the parent had not reduced or
waived income.
(a) The amount of potential income imputed (1) should not exceed the level it
would have been if there was no reduction in income, (2) not be based on
more than a 40 hour work week, and (3) not include potential overtime or
shift premiums.
2021 MICHIGAN CHILD SUPPORT FORMULA MANUAL
9
(b) Imputation is not appropriate where an individual is employed full time (35
hours per week or more, but has chosen to cease working additional hours
(such as leaving a second job or refusing overtime). Actual earnings for
overtime, second job, and shift premiums are considered income.
§
2.01(C)(1).
(2) Use relevant factors both to determine whether the parent in question has an
actual ability to earn and a reasonable likelihood of earning the potential income.
To figure the amount of potential income that parent could earn, consider the
following when imputing an income:
(a) Prior employment experience and history, including earnings history, and
reasons for any termination or changes in employment.
(b) Educational level, literacy, and any special skills or training.
(c) Physical and mental disabilities that may affect a parent’s ability to work, or
to obtain or maintain gainful employment.
(d) Availability for work (exclude periods when a parent could not work or
seek work, e.g., hospitalization, incarceration, debilitating illness, etc.).
(e) Availability of opportunities to work in the local geographical area.
(f) The prevailing wage rates and number of hours of available work in the
local geographical area.
(g) Diligence exercised in seeking appropriate employment.
(h) Evidence that the parent in question is able to earn the imputed income.
(i) Personal history, including present marital status, age, health, residence,
means of support, criminal record, ability to drive, and access to
transportation, etc.
(j) The presence of the parties’ children in the parent's home and its impact on
that parent’s earnings.
(k) Whether there has been a significant reduction in income compared to the
period that preceded the filing of the initial complaint or the motion for
modification.
(3) Imputation of potential income should account for the additional costs associated
with earning the potential income such as child care and taxes that a parent would
pay on the imputed income.
(4) Imputing an income to a parent to determine a support obligation by using any of
the following violates case law and does not comply with this section. See:
Ghidotti v. Barber, 459 Mich 189; 586 NW2d 883 (1998) and Stallworth v
Stallworth, 275 Mich App 282 (2007).
(a) Inferring based on generalized assumptions that parents should be earning
an income based on a standardized calculation (such as minimum wage and
full time employment, median income, etc.), rather than an individual’s
actual ability and likelihood.
2021 MICHIGAN CHILD SUPPORT FORMULA MANUAL
10
(b) Absent any information or indication concerning a parent’s ability,
assuming that an individual has an unexercised ability to earn an income.
(c) Failing to articulate information about how each factor in §2.01(G)(2)
applies to a parent having the actual ability and a reasonable likelihood of
earning the imputed potential income, or failing to state that a specific
factor does not apply.
(d) Inferring that commission of a crime is voluntary unemployment, without
evidence that the parent committed the crime with the intent to reduce
income or to avoid paying support.
(5) The court makes the final determination whether imputing a potential income is
appropriate in a particular case.
2.01(H) Interest earned or potentially earned on inheritances and gifts (§2.05(B)) should be
considered as income. Impute a reasonable rate when determining the potential
investment return that could be earned.
2.01(I) Except as provided in §2.01(K), attribute all dependent benefits from government
insurance programs that are based on the earnings record of a parent and paid for the
children-in-common as the earning parent’s income. Benefits include amounts paid
from insurance programs like social security, veteran’s administration, or railroad
retirement.
2.01(J) Custodial parent income includes all retirement, survivor’s, or disability dependent
benefits from government insurance programs like social security, veteran’s
administration, or railroad retirement that are received for the children-in-common
based on the earnings record of someone other than a parent.
2.01(K) When a parent receives retirement, survivor’s, or disability benefits from a government
insurance program like social security, veteran’s administration, or railroad retirement
and the children-in-common qualify to receive dependent benefits based on multiple
adults’ earnings records and a party provides sufficient documentation to distinguish on
whose behalf amounts are paid, attribute the children’s benefits as income between the
parents as follows:
(1) Because dependent benefits are paid based on the adult’s earnings record that
results in the highest benefit for the children, include the amount of dependent
benefits for the children-in-common that would be attributable to the support
payer’s earnings record as that parent’s income because it is credited against the
payer’s obligation under §3.07.
(2) If the children-in-common’s remaining benefits are paid based on the other
parent’s earnings record, include any benefit amounts that exceed amounts
considered as the support payer’s income under this subsection as the other
parent’s income.
2.01(L) Do not consider any monies (e.g., social security or other similar dependent benefits,
child support, etc.) that a parent receives for the care of additional children not in
common with the other parent in this case, nor any dependent benefits paid on a
parent’s behalf for those children.
2021 MICHIGAN CHILD SUPPORT FORMULA MANUAL
11
2.01(M) Income includes reimbursements (including per diem) from an employer for travel or
other expenses that exceed actual costs incurred.
(1) Absent documentation or other proof of the parent’s actual costs, presume that the
costs incurred were at the standard rates allowed by the state of Michigan for
employee travel (including per diem and mileage).
2.02 Seasonal and Annual Variation
2.02(A) Where monthly income varies due to seasonal factors (e.g., overtime, second jobs,
bonuses, or profit sharing) calculate income using information from at least the
preceding twelve months.
2.02(B) Where income varies considerably year-to-year due to the nature of the parent’s work,
use three years’ information to determine that parent’s income.
2.02(C) Evidence showing that overtime, second job, or other types of income will vary in the
future may be considered.
2.03 Children’s Income
2.03(A) A child’s income should not ordinarily be considered in calculating child support.
2.03(B) A child’s Supplemental Security Income (SSI) benefits cannot be considered as income,
nor used to reduce a parent’s support obligation.
2.04 Means Tested Income
2.04(A) Income does not include the value of benefits from means tested sources such as
Temporary Assistance to Needy Families (TANF), food stamps, the federal Earned
Income Credit, and Supplemental Security Income (SSI).
2.05 Inheritances and Gifts
2.05(A) Income generally does not include property or principal from an inheritance or one-time
gift.
2.05(B) Income includes the interest as well as potential interest (§2.01(H)) earned on inherited
property, and gifts.
2.05(C) Income may include the value of gifts or gratuities such as money, food, shelter,
transportation, or other goods or services that a parent receives from relatives (other
than a spouse), friends, or others, to the extent it:
(1) Is significant and regularly reduces personal expenses, or
(2) Replaces or supplements employment income.
2.06 Low Income Producing Assets
2.06(A) To the extent a parent’s assets could be (but are not) used to generate regular income, a
parent’s income includes an imputed reasonable and regular investment return on those
assets, except a home and its reasonable furnishings, an automobile, and other small
items of personal property.
2021 MICHIGAN CHILD SUPPORT FORMULA MANUAL
12
2.07 Allowable Deductions from Income
2.07(A) Alimony/Spousal Support
(1) Deduct alimony/spousal support paid to someone other than the other parent in
the case under consideration from its payer’s income after deducting federal,
state, and local income taxes, and deducting other mandatory federal taxes (e.g.,
FICA).
(2) Alimony/spousal support paid between the parents in the case under consideration
is not included as its recipient’s income, but remains its payer’s income.
2.07(B) Income and FICA/Medicare Taxes
(1) Deduct a parent’s actual income taxes from income.
(2) If tax returns are not made available, taxes should be estimated based on the best
available information and the estimation procedures described below.
(3) In the absence of an explicit written agreement or order to the contrary, presume
that the person with whom the child resides for the majority of a calendar year
claims the dependent tax exemption for that child.
(a) In determining filing status (Single or Married), presume the status most
consistent with each parent’s situation.
(b) Use income tax guides to determine the taxes deducted from gross earnings
for a parent’s actual number of dependent exemptions.
(c) To the extent possible, estimate taxes at rates that the parent would likely
pay for the income types attributed to that parent.
2.07(C) Deduct any mandatory payments as a condition of employment (e.g., required union
dues and nondiscretionary retirement contributions).
2.07(D) Deduct life insurance policy premiums when children-in-common with the other parent
are the beneficiaries.
(1) Only deduct term life insurance premiums paid on coverage ordered by the court.
(2) With whole life insurance policies that provide coverage ordered by the court,
only deduct an amount equivalent to the cost of the same amount of term life
insurance.
2.07(E) Deduct the cost of care or services paid by a parent to comply with case service or
permanency plan requirements in child protective or juvenile delinquency proceedings.
2.07(F) Deduct a parent’s net actual cost of providing mandatory health care coverage for
himself or herself. Calculate this deduction by figuring the net health care premiums
[costs minus any reimbursements, subsidies, or credits] paid by the parent and dividing
by the number of individuals covered (including the parent).
2.07(G) Do not include employer reimbursements for the actual costs incurred for travel (subject
to §2.01(M)), tuition, educational costs, and uniforms as income.
2.08 Additional Children from Other Relationships
2.08(A) Additional (biological or adopted) minor children include:
2021 MICHIGAN CHILD SUPPORT FORMULA MANUAL
13
(1) Those from a relationship with someone other than the other parent in the case
under consideration.
(2) Those in common with the other parent in this case who live in a nonparent’s
custody, when determining support for children living with either parent.
(3) Those in common with the other parent in this case who live with either parent,
when determining support for other children-in-common who live in a
nonparent’s custody.
2.08(B) When a parent has additional minor children (whether living in that parent’s household
or for whom the parent pays child support), net income for calculating support in the
present case does not include monies for children not in common with the other parent
in the case under consideration (§2.01(L)), nor the portion of that parent’s income
reserved for supporting additional children calculated according to both of the following
steps:
(1) Deduct from a parent’s income dollar-for-dollar the portion of that parent’s health
insurance premiums used to cover qualifying additional children. Calculate the
premium deduction by dividing the premium by the number of individuals
covered (including the parent) and multiply by the number of qualifying
additional children covered.
(2) After subtracting qualifying additional children’s health care coverage costs,
multiply that parent’s remaining net income by the Additional Children table’s
Adjustment Multiplier to determine net income to use for the present case.

2.09 Low Income Threshold and Family Net Income
2.09(A) “Low Income Threshold” is the individual income level specified in the current
supplement to this manual.
2.09(B) When one parent’s net income does not exceed the Low Income Threshold, do not
include that parent’s income in the monthly net family income used to calculate the
other parent’s general care support obligation. §3.02(B).
2021 MICHIGAN CHILD SUPPORT FORMULA MANUAL

3. CALCULATING EACH PARENT’S OBLIGATION
The next step in determining each parent’s child support obligation is to calculate the components
of each parent’s support obligation based on their net income as determined in Chapter 2.
3.01 Child Support Obligations
3.01(A) A parent’s child support obligation consists of
(1) a base support obligation (§3.02) adjusted for parenting time (§3.03);
(2) medical support obligations that include ordinary and additional (extra-ordinary)
medical expenses (§3.04), health care coverage and division of premiums (§3.05);
and
(3) child care expense obligations (§3.06).
3.01(B) Generally, support obligations should be apportioned between the parents based on each
parent’s percentage share of their combined net incomes.
(1) When figuring the percentage to use to apportion the base support obligation
using the General Care Equation (§3.02(B)), only include a parent’s net income if
it exceeds the Low Income Threshold (§2.09(A)), and round the resulting
percentages to the nearest hundredth percent.
(2) The medical support and child care obligations’ percentages should be based on
both parents’ net incomes and rounded to the nearest whole percent, but each
parent’s share cannot be less than 10 percent or more than 90 percent.
3.02 Base Support Obligation
3.02(A) To even out support amounts for children of the same parents, whether ordered in one
case or multiple cases, calculate base support using the total number of children-in-
common.
(1) If less than all of the children-in-common are included, then the present case’s
base support and the parental time offset (§3.03) is its children’s per capita share
of what the amount would be if all of the children-in-common were included on
one case.
(2) When some of the children-in-common are in a nonparent’s custody, calculate the
base support for the children in a parent’s custody separately from the base
support for those who live with a nonparent-custodian. §2.08(A) and §4.01.
3.02(B) General Care Equation
(1) Determine the monthly family income by combining the parents’ net incomes.
Only include a parent’s net income if it exceeds the Low Income Threshold
(§2.09).
(2) Solve the following equation using the General Care Support Table (found in the
supplement) for the appropriate number of children that the parents have in
common and its amounts and percentages from the highest monthly income level
that does not exceed the family’s net monthly income.
2021 MICHIGAN CHILD SUPPORT FORMULA MANUAL
16
{A + [B x (C – D)]} x E = G
A = Base Support (General Care Support table, column 3)
B = Marginal Percentage (General Care Support table, column 4)
C = Monthly Net Family Income (§3.02(B)(1))
D = Monthly Income Level (General Care Support table, first column)
E = Parent’s Percentage Share of Family Income (§3.02(B)(1))
G = Base Support obligation using the General Care Equation (round to the nearest whole dollar
)
(3) Subject to §3.02(D), when a parent’s net income exceeds the Low Income
Threshold (§2.09(A)), that parent’s base support obligation is the amount
determined using the General Care Equation.
(4) In most instances when a family’s net monthly income exceeds the highest
income level in the current supplement’s General Care Support Tables, the
parents’ base support obligations will be determined using the General Care
Equation. However when a family’s net income greatly exceeds the highest
income level, the court may exercise discretion as provided in §3.02(E).
3.02(C) Low Income Equation
When a parent’s monthly net income does not exceed the Low Income Threshold, the
parent’s base support obligation is 10 percent of that parent’s income. The Low Income
Equation is designed to retain funds for the parent’s subsistence.
F x 10% = L
F = Parent’s Monthly Net Income, when below the Low Income Threshold (§2.09(A))
10% = Percentage for Income below the threshold
L = Base Support (round to the nearest whole dollar
)
3.02(D) Low Income Transition Equation
When a parent’s net income exceeds the Low Income Threshold, that parent’s base
support obligation will generally be determined using the General Care Equation.
However, if the following equation’s result is lower than the amount calculated using
the General Care Equation, a parent’s base support obligation is the amount determined
by applying this equation. The Low Income Transition Equation is designed to balance
a parent’s subsistence needs with the costs of raising children in another household.
(H x 10%) + [(I - H) x P] = T
H = Low Income Threshold (§2.09(A))
10% = Percentage for Income below the threshold (§3.02(C))
I = Parent’s Monthly Net Income
P = Percentage Multiplier for the appropriate number of children from the Transition Adjustment

3.02(E) Extremely High Family Incomes
(1) The court should exercise discretion when a family’s income used to calculate
support greatly exceeds the highest “Income Amount” in the General Care
Support Tables found in the current supplement to this manual.
(2) When exercising discretion and trying to arrive at an appropriate result in an
extremely high-income case, provided the result meets each child’s needs, the
court may calculate the child support amounts by using the “Base Support” from
the appropriate General Care Support Table and other marginal percentages, or
choose to fashion another outcome that financially benefits the children and
protects each child’s interests in the inherent obligation each parent owes to the
child. See 2021 MCSF-S 2.03(B).)
3.03 Adjusting Base Obligation with the Parental Time Offset
3.03(A) Presuming that as parents spend more time with their children they will directly
contribute a greater share of the children’s expenses, a base support obligation needs to
offset some of the costs and savings associated with time spent with each parent. (The
supplement to this manual contains a graph and other information about adjusting
support payments for parenting time.)
(1) Base support mainly considers the cost of supporting a child who lives in one
household. When a parent cares for a child overnight, that parent should cover
many of the child’s unduplicated costs, while the other parent will not have to
spend as much money for food, utility, and other costs for the child.
(2) Apply the following Parental Time Offset Equation to adjust base support to
reflect some of the cost shifts and savings associated with the child spending time
with both parents:

Note: A negative result means that parent A pays and a positive result means parent B pays.
3.03(B) Application
(1) An offset for parental time generally applies to every support determination
whether in an initial determination or subsequent modification, whether or not
previously given.
(2) The parental time offset does not apply when a nonparent has custody of a child.
(§1.04(E)(16) and (§4.01(A)).
3.03(C) Apply the parental time offset to adjust a base support obligation whenever the
approximate annual number of overnights that each parent will likely provide care for
the children-in-common can be determined. When possible, determine the approximate
number based on past practice.
(1) When different children spend different numbers of overnights with the parents,
use the average of the children’s overnights.
(2) Absent credible evidence of changed practices, presume the same approximate
number that was used in determining the most recent support order.
(3) In cases without a past determination or other credible evidence, presume the
approximate number of overnights granted in the terms of the current custody or
parenting time order.
(4) Credit a parent for overnights a child lawfully and actually spends with that parent
including those exercised outside the terms of the currently effective order. This
may happen by agreement, or when one parent voluntarily foregoes time granted
in the order. Do not consider overnights exercised in violation of an order.
(a) If a parent produces credible evidence that the approximate number
exercised differs from the number granted by the custody or parenting time
order, credit the number according to the evidence without requiring
someone to formally petition to modify the custody or parenting time order.
(b) When the most recent support order deviated based on an agreement to use
a number of overnights that differed from actual practice, absent some other
change warranting modification, credible evidence of changed practices
only includes an order changing the custody or parenting time schedule.
3.03(D) If a substantial difference occurs in the number of overnights used to set the order and
those actually exercised (at least 21 overnights or that causes a change of circumstances
exceeding the modification threshold (§4.05)), either parent or a support recipient may
seek adjustment by filing a motion to modify the order.
3.03(E) So the court can know if circumstances have changed at the time of a subsequent
determination, every child support order must indicate whether it includes a parental
time offset and the number of overnights used in its calculation.
2021 MICHIGAN CHILD SUPPORT FORMULA MANUAL
19
3.04 Medical (Health Care) Obligations
3.04(A) Obligations Generally
(1) The term “medical” includes treatments, services, equipment, medicines,
preventative care, similar goods and services associated with oral, visual,
psychological, medical, and other related care, provided or prescribed by health
care professionals for the children.
(2) Routine remedial care costs for children (e.g., first-aid supplies, cough syrup, and
vitamins) do not qualify as medical expenses.
(3) Ordinary medical expenses include the support recipient’s co-payments and
deductibles, and uninsured medical-related costs for all children in this case.
Ordinary medical expenses presume that the recipient is the individual who
typically obtains medical care for the children for whom support is paid, and
therefore normally has out-of-pocket expenses needing reimbursement.
(4) Additional (extra-ordinary) medical expenses consist of the support recipient’s
out-of-pocket expenses that exceed the children’s ordered annual ordinary
medical expense amount and any uninsured medical expense paid by the support
payer.
(5) Every support order should specify the medical expense percentage based on each
parent’s share of the family income (§3.01(B)(2)) for uninsured medical expenses
for which each parent is responsible.
(6) A parent’s or custodian’s qualifying medical expenses include those paid with
monies from a health savings account or flexible benefit account, provided that
account is funded, in whole or part, with monies reported as that individual’s
income.
3.04(B) Ordinary Medical Expense Obligations
(1) In order to reimburse the support recipient’s qualifying medical expenditures for
the children within the same calendar year, almost every support order should set
an appropriate annual ordinary medical expense amount for the children and
apportion payment of the annual amount between the parents according to each
parent’s percentage share of family income.
(2) When setting the annual amount, presume that the amount listed for the
appropriate number of children in Ordinary Medical Expense Average Table
(found in the supplement) is the amount that will be spent on ordinary medical
expenses. Amounts may be added to the Table amounts to compensate for higher
uninsured expenses that can be predicted in advance (e.g., orthodontia, special
medical needs, or ongoing treatments).
(3) The court may determine that no ordinary medical expense amount is appropriate
and treat all qualifying medical expenses as additional medical expenses
(§3.04(A)(4)) when any following circumstance exists: (a) both parents routinely
take one or more children-in-common for medical care and incur qualifying
medical expenses, (b) the support payer will likely incur most qualifying out-of-
pocket costs for the children, (c) an incapacitated payer’s base support obligation
is set at zero (§4.02), or (d) the recipient has an employer-paid benefit (e.g., health
2021 MICHIGAN CHILD SUPPORT FORMULA MANUAL
20
reimbursement arrangement) that pays the recipient’s initial out-of-pocket
expenses for the children.
(4) Ordinary Expense Payments
(a) The annual ordinary medical expense amount restarts every calendar year
and remains in effect with the rest of the support obligation or until further
order of the court.
(i) The support payer’s apportioned share of ordinary medical expenses
should be ordered paid as part of the monthly support obligation and
maintained by the support recipient.
(ii) The support recipient’s apportioned share of ordinary expenses is
directly contributed by the recipient as expenses occur.
(b) Ordinary Medical Expense Accounting
(i) All qualifying expenditures are considered made in proportion to each
parent’s medical expense percentage established in the order.
(ii) Presume that the annual amount will be spent. The recipient does not
have to routinely provide proof of its expenditure.
(iii) In order for a support recipient to seek reimbursement of additional
medical expenses, the recipient needs to show that the ordered total
annual ordinary medical expense amount for all children was exceeded.
(c) Prorate ordinary medical expense amounts for partial periods during which
they are in effect.
3.04(C) Additional (Extra-ordinary) Medical Expenses
Additional expenses should be apportioned between the parents according to the
medical expense percentages established in the support order.
3.04(D) Unreimbursed Medical Expense Minimum Enforcement Threshold
(1) State law establishes that complaints seeking enforcement of unreimbursed
additional medical expenses (§3.04(A)(4)) must meet a minimum threshold before
a friend of the court office is required to act on that complaint. MCL 552.511a
.
(2) The “minimum enforcement threshold” under MCL 552.511a(1)(b) for additional
medical expenses is $100 per child each calendar year, or a lower amount set by
the court. If unreimbursed additional expenses do not exceed the threshold before
a year ends, those expenses may be submitted to the FOC for enforcement before
the deadline under
MCL 552.511a(1)(c).
3.05 Health Care Coverage Obligation and Premiums
3.05(A) Health Care Coverage, Accessibility, and Cost
(1) The Support and Parenting Time Enforcement Act defines health care coverage as
“a fee for service, health maintenance organization, preferred provider
2021 MICHIGAN CHILD SUPPORT FORMULA MANUAL
21
organization, or other type of private health care coverage or public health care
coverage.” MCL 552.602(n)
(a) Private coverage means health care coverage obtained through an employer
or purchased by an individual from an insurer.
(b) Public coverage means health care coverage that is established or
maintained by a local, state, or federal government like Medicaid or SCHIP.
(2) Reasonable Cost of Coverage
Except as otherwise ordered by the court, a reasonable cost to a parent for
providing health care coverage for the children does not exceed 6 percent of the
providing parent’s gross income. In applying this standard, the cost of providing
health care coverage is the parent’s net cost of adding the children to the parent’s
coverage (e.g., difference between self-only and family coverage) or adding the
children to the existing coverage.
(a) Parents with a net income below 133 percent of the federal poverty level or
whose child is covered by Medicaid based on that parent’s income should
not be ordered to contribute toward or provide coverage, unless coverage is
obtainable without any financial contribution by that parent.
(b) A parent’s cost for providing health care coverage is unreasonable if the
parent’s total current obligation for support, child care expenses, ordinary
health care expenses, plus the parent’s net share of health care insurance
exceeds 50 percent of the parent’s regular aggregate disposable earnings.
(3) Accessible to the Child
Health care coverage is presumed accessible if primary care services are covered
within 30 miles or 30 minutes from any of a child’s residences. Coverage may be
considered at greater times and distances in areas where residents normally travel
longer to access primary care services.
3.05(B) Responsibility to Insure
(1) When ordering child support, the court must order one of the parents to maintain
health care coverage that is accessible to the children and available to the parent at
a reasonable cost. MCL 552.605a(2)
requires the presumptive use of this manual
to determine whether coverage is accessible and available at a reasonable cost,
and also permits the court to exercise discretion when ordering coverage.
(a) To prevent duplicate coverage, extra costs, and avoid unnecessary
enforcement actions, only one parent should be ordered to maintain
coverage.
(b) The court should avoid routinely requiring both parties to provide coverage.
MCL 552.605a(2)
allows ordering both parents to maintain coverage when
both parents already provide coverage or both agree to provide coverage.
(2) Many factors may be used to determine which parent should maintain employer,
group, individual, or public coverage for their children. When comparing plans,
consider factors like: the accessibility and comprehensiveness of covered services,
likely continuation of coverage, affordability of deductibles and co-payments, and
2021 MICHIGAN CHILD SUPPORT FORMULA MANUAL
22
reasonableness of the premiums. (The supplement to this manual contains a guide
to determine which parent should be ordered to maintain health care coverage.
2021 MCSF-S 3.02.)
(3) The court may permit a parent to provide required coverage through alternative
means, such as a spouse’s or other household member’s coverage or coverage
provided by a nonparent-custodian (§4.01(D)(6)), provided that a parent is
required to purchase coverage immediately should the alternative coverage stop.
3.05(C) Health Care Premium Allocation
(1) The children’s net determinable portion of health insurance premiums paid by the
parents to cover the children should be apportioned according to each parent’s
percentage share of family income. §3.01(B)(2).
(a) The difference between the parents’ shares of the net determinable amounts
should be included (as an addition or subtraction) as part of the support
payment.
(b) Adjust base support by adding the net health care premium attributable to
the children (whether positive or negative) to the base support obligation
after applying the parental time offset formula.
(c) If the parent provides insurance for the children-in-common using a
spouse’s or household member’s benefits, consider amounts paid by the
parent’s household as the parent’s premiums paid to insure the children.
(2) Subject to §4.01(D)(5), allocate the children’s net health care premiums for
parent-provided insurance between the parents according to the following steps.
(a) Determine each parent’s monthly net health care premium attributable to the
children by dividing the net premium (actual cost to the parent after
subtracting any tax credits, subsidies, other reimbursements, and amount
deducted for self-coverage under §2.07(F)) by the number of individuals
covered and multiply by the number of children covered in this case.
(b) Prorate each parent’s monthly health care premium attributable to the
children by multiplying it and the other parent’s percentage of family
income.
(c) Offset the prorated premiums attributable to the children by subtracting the
support recipient’s share of the support payer’s premium from the payer’s
share of the recipient’s premium, and round to the nearest cent. (Note: A
positive net result means an additional amount must be paid to cover the
payer’s share of the support recipient’s premium, while a negative result
means a reduction in base support to offset the support recipient’s share of
the payer’s premium).
3.06 Child Care Support Obligations
3.06(A) Based on each parent’s percentage share of family income, allocate the actual child care
expenses for the children in the case under consideration which allow a parent or
nonparent-custodian to look for employment, retain employment, or to attend an
educational program to improve employment opportunities.
2021 MICHIGAN CHILD SUPPORT FORMULA MANUAL
23
(1) When custodians or parents have an established child care pattern and can verify
that they have actual, predictable and reasonable child care expenses, use the
actual costs in the calculation.
(2) When no established pattern of child care expenses exists, base the expenses on
estimates of the community’s average child care costs or several written
quotations from local child care providers.
(3) In calculating child care expenses, presume that the court’s orders for specific
parenting time and custody will be followed. However, if a child care provider
requires payment to retain a slot for a child without regard to whether the child
actually attends, include those additional costs.
3.06(B) Figure the actual cost of child care by deducting any child care subsidies, credits
(including federal tax credit), or similar public or private reimbursements from the gross
cost of child care.
3.06(C) The support payer’s net portion of the actual child care expenses should be ordered paid
as a monthly child care support obligation. The support recipient’s share of child care
expenses is directly contributed by the support recipient as expenses occur. Allocate net
child care costs according to the following steps.
(1) Determine each individual’s actual monthly child care.
(a) Calculate each individual’s gross annual child care expenditures.
(b) Figure the actual cost by deducting any child care subsidies, credits
(including tax credits), or reimbursements from the gross cost of child care
and convert to a monthly amount.
(2) Allocate the actual monthly costs by multiplying by the other parent’s percentage
share of family income. §3.01(B)(2).
(3) Offset the two prorated amounts by subtracting the other parent’s share of the
support payer’s monthly costs from the payer’s share of the other parent’s
monthly costs.
3.06(D) Presume that the need for child care continues until August 31 following the child’s
twelfth birthday, and unless otherwise stated in the order the total child care reduces by
the child’s pro rata share upon that date. At the court’s discretion, the child care support
obligation may continue beyond that date as a child’s health or safety needs require.
3.06(E) Since child care support obligations accrue based on the assumed continuation of the
net expenses used to set the currently effective order, custodians and parents need to
notify each other of changes in costs, and must notify the friend of the court when they
stop incurring child care expenses for a child.
3.06(F) When parents or custodians do not have an established pattern of child care expenses,
the court can order a reasonable amount for future child care expenses conditioned upon
the support recipient providing to the other parent and the friend of the court (1) proof
of the recipient’s employment or enrollment in a qualifying educational or training
program, (2) proof of the recipient’s actual out-of-pocket child care expenses, (3) a
written request to the friend of the court asking for implementation of the conditional
2021 MICHIGAN CHILD SUPPORT FORMULA MANUAL
24
child care provision, and (4) proof that the support payer was provided copies of items
(1)-(3).
3.07 Dependent Benefit Credit
3.07(A) Credit government insurance program retirement, survivor’s, or disability benefits that
were counted as the support payer’s income under §2.01(I) or §2.01(K) against the
payer’s support obligation as follows:
(1) Determine the total child support obligation.
(2) Subtract the monthly benefit amount that the recipient receives for the children
and that is attributable to the payer from the total child support obligation owed
by the payer.
(a) If the children’s payer-based benefit exceeds the total support amount, then
no additional support amount should be ordered.
(b) If the children’s payer-based benefits are less than the payer’s total support
amount, then the difference between the benefits received for the children
and the total support amount becomes the ordered obligation.
(3) Under federal law, the administering agency, like the Social Security
Administration, holds the sole authority to designate the person who controls the
benefits for a minor child (representative payee), therefore, a State’s legal
processes cannot be used to alienate federal benefits from a child’s representative
payee. A court should not use a child support order to transfer the children’s
benefits from a representative payee to a parent or another individual. Payer-based
benefits that exceed the total child support obligation owed must remain under the
control of the representative payee.
(4) Because each parent has an individual obligation to provide for that parent’s
children, benefits based on another person’s earnings record cannot be credited
against or used to satisfy the payer’s support obligation except as permitted under
§2.01(K).
3.07(B) The following cases discuss how Social Security benefits affect support obligations:
Frens v Frens, 191 Mich App 654 (1990); Jenerou v Jenerou, 200 Mich App 265
(1993); Paulson v Paulson, 254 Mich App 568 (2002); and Fisher v Fisher, 276 Mich
App 424 (2007).

4. OTHER FACTORS
4.01 Nonparent-Custodians
4.01(A) When a nonparent has custody of a child, both parents should pay support. Determine
each parent’s base support obligation according to that parent’s individual income.
4.01(B) Parents are responsible for all medical expenses, health care coverage premiums, and
child care expenses for children in a nonparent-custodian’s care. When possible,
apportion those costs between the parents.
4.01(C) In determining a parent’s net income amount that will be used to calculate support for
children in the care of a nonparent, treat the parents’ other children-in-common who are
not in the nonparent’s custody as additional children from other relationships
(§2.08(A)).
4.01(D) When a child is in a nonparent’s physical custody, calculate each parent’s support
obligation for that child based only on that parent’s income, as follows:
(1) Determine each parent’s net income.
(2) Calculate each parent’s base support obligation separately by treating the other
parent’s income as zero, and do not apply the Parental Time Offset Equation
(§1.04(E)(16) and (§3.03(B)).
(3) Calculate medical expense and child care support obligations and require payment
from only the parents. When possible, divide them between the parents based on
each parent’s percentage share of family income.
(4) Total a parent’s base support, ordinary medical expense, and child care
obligations to determine that parent’s total support obligation payable to the
nonparent.
(5) Do not reduce a parent’s base support obligation paid to a nonparent-custodian for
health care coverage premiums paid by a parent. Allocation of parent-paid
premiums between the parents should be handled separately.
(6) If the nonparent-custodian purchases health care coverage for the children, add
each parent’s share of the children’s net determinable portion of the premiums
paid by the nonparent-custodian to that parent’s support payment.
4.02 Incapacitated Parent
4.02(A) “Incapacitation” means the inability to pay the ordered support obligation caused by a
parent being temporarily or permanently unable to earn an income for a period that will
likely last 180 days or longer and that is due to disability, mental incompetency, serious
injury, debilitating illness, or incarceration. Beyond the financial impacts,
incapacitation often limits the parent’s ability to act in his or her own self-interests. At
its onset, the exact duration and full impact of an incapacitating condition will often be
uncertain.
(1) Due to the statutory restriction to retroactively modifying a final judgment or
order, an action to modify support should start as soon as possible.
2021 MICHIGAN CHILD SUPPORT FORMULA MANUAL
26
(2) The court may exercise discretion and grant relief when the actual duration is less
than 180 days.
(3) Often, a parent’s income does not immediately return to what it was before the
parent became incapacitated.
(4) The court makes the final determination whether a parent is unable to earn an
income or otherwise qualifies as incapacitated under this section.
4.02(B) The court may set an incapacitated payer’s (§4.02(A)) child support obligation at zero
for periods that a parent has an inability to pay due to a loss of income and insufficient
assets from which to pay support.
4.02(C) The court should reduce the effect of the time needed to complete a review and avoid
the bar on retroactive modification by including prospective language in support orders
that abates support for periods when a payer is incapacitated.
4.02(D) It may take one or more years before a parent actually receives benefits or settles a
lawsuit. Sometimes funds are paid retroactively to compensate the incapacitated parent
for prior months when the parent was unable to work. When there is uncertainty
regarding a future outcome or when the payer may receive retroactive compensation or
benefits, the court may defer a final decision and preserve flexibility to set an
appropriate amount for the period following notice to the parties by entering a
temporary order that remains modifiable until uncertainty ends. Fisher v Fisher, 276
Mich App 424 (2007).
4.02(E) The supplement to this manual contains additional information on Adjusting
Incapacitated Parents’ Obligations. (2021 MCSF-S 3.04).
4.03 Arrearage Guideline
4.03(A) State law requires that Michigan’s formula include guidelines to figure payments for
overdue support, and when support for a child terminates and arrearages are owed.
MCL 552.519(3)(a)(vi)
.
(1) Federal law requires states to have procedures to increase the amount of payments
to include amounts for arrearages. 42 U.S.C. 666(c)(1)(H).
(2) State law requires friend of the court offices to use the Arrearage Guideline in
setting or adjusting arrearage payments. MCL 552.517e
.
(3) This Arrearage Guideline is not intended to interfere with the enforcement of
past-due support and its collection through concurrent means that do not rely on
regular payments.
(4) This Arrearage Guideline is not intended to interfere with judicial discretion to set
fair and equitable repayment amounts that deviate from the Guideline.
4.03(B) Arrearage Payment Calculation
(1) Arrearages should be repaid as quickly as possible.
(2) If the entire arrearage cannot be paid immediately, the Arrearage Guideline
should be used to set a repayment amount where support or fees are owed.
2021 MICHIGAN CHILD SUPPORT FORMULA MANUAL
27
(3) Subject to (6)-(8) below, a monthly repayment amount is 2 percent of the total
support arrearage at the time of the review, but not less than $50, nor more than
half of the current support amount. Or, if no current support charge exists, then
the monthly repayment amount is the last ordered charge amount.
(a) When applying the Guideline, any monies held or retained by the friend of
the court office or the State Disbursement Unit as payment of past due child
support should be subtracted from the amount of arrearage used to calculate
the repayment amount.
(4) Payments set by this Guideline should be rounded to the nearest whole dollar
amount.
(5) The monthly birth-related expense repayment amount (i.e., payment for current
month, not past due amounts) should not be less than $25, nor more than the
birth-related expenses’ pro-rata share of the total amount of birth-related and
arrearages owed. Statutes, regulations, and other policy determine how these
amounts will be distributed on a specific case.
(6) In order to repay arrearages as quickly as possible, the “total-payment-amount”
(defined in §4.03(E)(4)) used for determining the repayment amount for
collection must be the higher of: the most recent total-payment-amount, or the
total-payment-amount presently figured using the arrearage payment calculation
and current support charge.
(a) If the support charge is reduced because of a reduction in payer’s income
always refigure the repayment amount using the arrearage payment
calculation (§4.03(B)(3)) and the current support charge.
(7) If the most recent total-payment-amount is the payment amount chosen, the
aggregate amount remains the same, but consists of a reduced support and an
increased repayment amount (§4.03(B)(8)).
(8) Adjustment of Payments When Current Support Obligations Terminate
(a) If arrearages exist when a current support obligation terminates or is
reduced for reasons other than a reduction in the payer’s income, there shall
be no automatic reduction in the total-payment-amount unless ordered by
the court.
(b) The reductions in the current support amount are added to the repayment
amount and automatically become the new repayment amount.
(c) The total-payment-amount remains in effect until the arrearage has been
paid in full or until modified or adjusted by the court or friend of the court.
4.03(C) Guideline Deviation and Exceptions
(1) When application of this Guideline creates an unjust or inappropriate result,
deviation may occur and an alternate repayment amount may be established.
(2) The friend of the court office may deviate from the Guideline to increase the
repayment amount if:
2021 MICHIGAN CHILD SUPPORT FORMULA MANUAL
28
(a) there has been no other significant change in circumstances (e.g., different
source of income, higher income, etc.),
(b) the payer has made all of the payments for the entire period since the
repayment amount was set, and
(c) the arrearage has nevertheless increased by an amount greater than one
month’s current support obligation solely because surcharge has
periodically added to the arrearage.
(3) The friend of the court should not routinely apply the Arrearage Guideline to
administratively change repayment amounts in cases where:
(a) The court has ordered a specific periodic arrearage payment, and since entry
of that order, the arrearage has not increased by at least one month’s support
obligation based on the current support amount (if no current support charge
use the last ordered charge amount) and the payer’s support obligation has
not decreased.
(b) The total arrearage has been reduced, but has not yet been paid in full since
the repayment amount was set (because applying the Guideline to a
decreased arrearage total would unnecessarily extend the repayment
period).
(c) The court previously ordered or the friend of the court administratively set a
repayment amount that deviated from the Guideline either to avoid an
unjust or inappropriate result or because of a formal agreement between the
parties, and circumstances have not significantly changed since then.
(d) In interstate cases where Michigan and another state’s tribunal have entered
an order regarding the same payer and child, and the support order and
arrears accumulated under the Michigan order are being enforced by
another jurisdiction.
4.03(D) Administrative Adjustment Records
(1) Friend of the court offices should maintain records of: (a) administratively set
repayment amounts, (b) repayment amounts that deviate from the Arrearage
Guideline, and (c) the reasons for any such deviation.
4.03(E) Definitions for the purpose of the Arrearage Guideline:
(1) Administrative adjustment means a change in an amount not ordered by the court.
(2) Repayment amount means periodic amounts in addition to current support
specifically designated to reduce the arrearage owed.
(3) Birth-related expenses means the support payer’s share of medical expenses
connected to the pregnancy and the birth of the child that the circuit court orders
repaid pursuant to
MCL 552.452 or MCL 722.712.
(4) Total-payment-amount means the sum of regular periodic current and past-due
support obligation, fees, and other payments required by court order or statute
(i.e., the total the court determined the parent could afford to pay) or
administratively set by the friend of the court office.

4.04 Agreements Related to Property
4.04(A) When parents reach an agreement that the court should deviate from the formula and
connect a property settlement with the child support obligation, the complete agreement
must be clearly stated in the judgment of divorce to be given continued effect.
MCL
552.605 requires that any property award that is in lieu of child support required under
the formula be recorded as a deviation from the formula.
4.05 Minimum Threshold for Modification
4.05(A) The “minimum threshold for modification” is 10 percent of the currently ordered
support payment or $50 per month, whichever is greater.
4.05(B) Following a child support review by the friend of the court office, if the difference
between the recommended amount and the current order exceeds the minimum
threshold for modification, the friend of the court office must petition the court to
modify the order.
4.06 Order Conversion, Prorating, and Rounding
4.06(A) To convert support amounts to their monthly equivalents, multiply weekly amounts by
4.35 and biweekly amounts by 2.175. See MCL 552.605c
.
4.06(B) To convert monthly support obligations into daily amounts, multiply by .033.
4.06(C) Whenever it is necessary to prorate support amounts for partial months, apply the
following equation:
C
b
- ((C
