Michigan counts Social Security Disability Insurance (SSDI) as income for child support, but credits any derivative benefits your children receive on your record against your obligation under Mich. Comp. Laws § 552.605 and MCSF 3.07(A). Supplemental Security Income (SSI) is excluded entirely. This guide explains how disability income and disabled children reshape a 2026 Michigan support order.

Child support in Michigan is calculated under the 2025 Michigan Child Support Formula (MCSF) Manual, effective January 1, 2025, which remains the governing formula in 2026. When a parent has a disability, the formula treats SSDI and derivative benefits through specific rules that can dramatically change the final ordered amount.
How Does Disability Affect Child Support in Michigan?
Disability affects child support disability Michigan cases through two distinct income sources: SSDI counts as income under MCSF 2.01, while SSI is excluded entirely. If a parent's only income is SSI, that parent cannot be ordered to pay child support. SSDI recipients can be ordered to pay, but any derivative benefit their child receives is credited against the obligation under MCSF 3.07(A).
The distinction between SSDI and SSI drives every disability income child support calculation in Michigan. Social Security Disability Insurance is an earned, work-record benefit funded through payroll taxes, so Michigan treats it as ordinary income like wages. Supplemental Security Income is a needs-based welfare program for low-income disabled individuals, and the Michigan Child Support Formula expressly directs courts not to count SSI as income when calculating support. This means a disabled parent whose sole income is a $967 monthly SSI check (the 2026 federal maximum) generally owes no child support, because the formula assigns them zero countable income for calculation purposes.
For SSDI recipients, the analysis is more layered. The parent's monthly SSDI benefit is added to income, then the formula runs the standard calculation under MCSF 3.02. If the child receives a derivative (dependent) benefit based on that same parent's earnings record, that benefit is credited against the resulting obligation. The disabled parent child support outcome therefore depends heavily on whether derivative benefits exist and whose record they derive from.
What Are SSDI Derivative Benefits and How Are They Credited?
SSDI derivative benefits are monthly payments the Social Security Administration pays to a disabled parent's minor children based on that parent's earnings record. Under MCSF 3.07(A), Michigan credits these child support disability payments against the payer's obligation dollar-for-dollar. If the derivative benefit exceeds the calculated support, no additional payment is ordered.
When a parent qualifies for SSDI, their dependent children can receive a separate monthly derivative benefit, often 50% to 80% of the parent's own benefit amount. Michigan's formula handles this through a two-step credit under MCSF 3.07(A). First, the court determines the total child support obligation using the standard formula. Second, the court subtracts the monthly derivative benefit the children receive on the payer's record from that total obligation. The result determines whether any cash payment is still owed.
The practical effect is significant. Consider a payer whose calculated obligation is $960 per month, and whose two children receive $1,100 monthly in SSDI dependent benefits on his record. Because the $1,100 derivative benefit exceeds the $960 obligation, no additional support is ordered — the children already receive more than the formula requires. If instead the derivative benefit were only $600, the payer would owe the $360 difference in cash. This crediting mechanism under Mich. Comp. Laws § 552.605 prevents double-counting while ensuring children receive their full entitled support.
Whose Earnings Record Matters for the SSDI Child Support Credit?
The SSDI child support credit only applies when the derivative benefit derives from the payer's earnings record. Under MCSF 3.07, a payer may not receive credit for benefits paid on another person's record. If children receive dependent benefits on the recipient parent's record instead, the payer owes the full calculated obligation with no reduction.
Michigan recognizes three distinct scenarios, and the disability income child support result changes dramatically depending on which applies. In the first scenario, the children's derivative benefit is based on the payer's earnings record. Here the benefit is both added to the payer's income under MCSF 2.01(K) and credited against the payer's obligation under MCSF 3.07(A) — this is the classic crediting case that can reduce or eliminate a cash payment.
In the second scenario, the derivative benefit derives from the recipient (custodial) parent's record. In that case, the benefit is counted as the recipient's income, but nothing is credited against the payer's obligation because the benefit is not based on the payer's earnings record. The payer owes the full amount calculated. In the third scenario, benefits are available on both parents' records; MCSF 2.01(K) directs that the amount be determined based on the earnings record producing the highest benefit for the children, with proper documentation required before amounts are attributed to more than one parent.
Can a Parent on SSI Be Ordered to Pay Child Support in Michigan?
A parent whose only income is SSI cannot be ordered to pay child support in Michigan. The Michigan Child Support Formula expressly excludes SSI from countable income under MCSF 2.01. Because SSI is a needs-based benefit for low-income disabled individuals, the 2026 federal maximum of $967 per month is treated as $0 income for support calculation purposes.
The SSDI child support versus SSI distinction protects genuinely destitute disabled parents from support orders they could never satisfy. Supplemental Security Income is designed as a floor of subsistence income, and both federal law and the Michigan formula shield it from garnishment for child support. When a parent presents documentation that SSI is their sole income source, the Friend of the Court and the court will typically enter a minimal or zero support order, sometimes reserving jurisdiction to revisit the figure if the parent's financial circumstances change.
However, the analysis shifts if the disabled parent has any additional income. A parent who receives SSI plus part-time wages, a pension, or SSDI will have those non-SSI sources counted normally. The court examines the complete income picture rather than stopping at the SSI label. This is why accurate income disclosure matters: a disabled parent child support case turns on precisely categorizing each dollar of income as countable (SSDI, wages, pensions) or excluded (SSI), because miscategorization can produce an order that is either unfairly burdensome or improperly low.
How Does Michigan Handle Child Support for a Disabled Child?
Michigan child support for a disabled child generally ends at 18, or at 19 years and 6 months if the child is still attending high school full-time, under Mich. Comp. Laws § 552.605b. Michigan has no automatic statute extending ordinary child support indefinitely for disabled adult children. Extended support is typically achieved through a written agreement in the divorce judgment.
The child support disabled child question is one of the most misunderstood areas of Michigan law. Under the Support and Parenting Time Enforcement Act, Mich. Comp. Laws § 552.605b permits a court to order support past 18 only while the child is regularly attending high school full-time with a reasonable expectation of graduating — and in no case beyond 19 years and 6 months of age. This hard cap applies regardless of whether the child has a disability. Michigan does not, unlike some states, automatically compel a parent to pay child support for a disabled adult child based on disability alone.
Parents seeking continued support for a disabled adult child in Michigan generally rely on a statutory exception in Mich. Comp. Laws § 552.605b: a provision for support after age 18 is valid and enforceable if it is contained in the judgment or order by agreement of the parties. Many divorcing parents of a special-needs child negotiate such a clause during the divorce, obligating continued financial support. Separately, a disabled child whose disability began before age 22 may qualify for Disabled Adult Child (DAC) Social Security benefits on a parent's work record, providing an independent income stream that does not depend on the child support order at all.
What Statutes and Court Rules Govern Michigan Child Support?
Michigan child support is governed primarily by the Support and Parenting Time Enforcement Act, Mich. Comp. Laws § 552.605, which requires courts to apply the Michigan Child Support Formula. The 2025 MCSF Manual, effective January 1, 2025, remains controlling in 2026 and details how disability benefits factor into the calculation under sections 2.01 and 3.07.
Several interlocking authorities shape any disabled parent child support case. The foundational statute, Mich. Comp. Laws § 552.605, directs courts to order support in the amount determined by the formula unless the court makes specific findings that formula application would be unjust or inappropriate. The formula itself — the 2025 MCSF Manual — governs the mechanics, with MCSF 2.01 defining countable income (including SSDI, excluding SSI) and MCSF 3.07(A) governing the derivative benefit credit.
Additional statutes address related issues. Mich. Comp. Laws § 552.605b sets the postmajority support cap at 19 years and 6 months and preserves party agreements for extended support. Mich. Comp. Laws § 552.602 provides the statutory income definitions, and Mich. Comp. Laws § 552.605a addresses mandatory health care coverage provisions in every support order. A 2025-2028 MCSF Review Committee is currently evaluating potential formula changes, so parents should confirm which manual version applies at the time their order is entered or reviewed.
How Do You Modify a Michigan Child Support Order for Disability?
A Michigan child support order can be modified when a parent proves a substantial change in circumstances, such as a new disability, loss of income, or a child beginning or losing derivative benefits. The Friend of the Court must open a support review upon credible evidence of changed financial needs. Reviews are also available every 36 months under Mich. Comp. Laws § 552.517.
Disability frequently triggers a modification because it changes income on both sides of the calculation. A payer who becomes disabled and begins receiving SSDI may see their countable income drop, warranting a downward modification. Conversely, when children begin receiving SSDI derivative benefits, the crediting rule under MCSF 3.07(A) can reduce or eliminate the payer's cash obligation — but only if the order is formally modified to reflect the credit. Parents should not simply stop paying; they must petition the court or request a Friend of the Court review.
The modification process begins by filing a motion to modify child support with the Circuit Court that issued the original order, or by requesting a Friend of the Court review. The moving party must present evidence — SSDI award letters, benefit statements, income documentation — establishing the changed circumstances. Michigan courts and the Friend of the Court then recalculate support under the current formula. Because disability calculations are technically complex and turn on whose earnings record generates any derivative benefit, many parents in child support disability Michigan modifications consult a family law attorney or the Friend of the Court to ensure the credit is applied correctly.
