How Child Support Works in New York: Formula, Filing, and Enforcement

Child support in New York works off a statutory formula: each parent’s income is combined, a set percentage tied to the number of children is applied, and the resulting obligation is split between the parents in proportion to what each one earns. The duty runs until the child turns 21, which is longer than most states, and it applies whether the parents were ever married or not.

Who Owes Support and Until What Age

Every parent in New York, biological or adoptive, owes financial support to each child until age 21.¹ Living arrangements and marital history don’t change that. Both parents are on the hook; the parent the child lives with most of the time typically receives support from the other.

Some events end the obligation early. A child who marries, enters full-time military service, or becomes self-supporting through full-time work is generally treated as emancipated. A working-age child who leaves the custodial home without good cause and refuses reasonable household rules can also lose the right to support. If any of that happens, the paying parent should return to court to have the order formally terminated rather than stopping payments on their own.

How the Formula Calculates the Basic Amount

The Child Support Standards Act sets fixed percentages of combined parental income based on how many children the parents share:

One child: 17%
Two children: 25%
Three children: 29%
Four children: 31%
Five or more children: no less than 35%

Those percentages apply to the first $193,000 of combined parental income. That cap took effect March 1, 2026, up from $183,000 during the prior two-year period, and it adjusts every two years based on the Consumer Price Index.² Above the cap, the court can either extend the same percentages to the excess or weigh a broader set of factors to decide what the additional amount should be.¹

Once the percentage produces a dollar figure, the court splits it between the parents in the same ratio as their incomes. If one parent brings in 60% of the combined total, that parent pays 60% of the obligation. The same ratio applies to add-on costs the court pro-rates on top of basic support: childcare, health insurance premiums, and unreimbursed medical expenses.³

What Counts as Income

Gross income starts with each parent’s most recent federal tax return and can include much more: investment income, workers’ compensation, disability benefits, unemployment insurance, pensions, and other recurring sources. Social Security Disability Insurance counts. Supplemental Security Income does not.

The statute allows specific deductions from gross income before the percentages get applied:

FICA taxes actually paid (Social Security and Medicare)
New York City or Yonkers income taxes actually paid
Alimony or maintenance paid under a court order or written agreement
Child support already paid for children from another relationship under a separate order
Unreimbursed employee business expenses that don’t reduce personal spending
Supplemental Security Income and public assistance received

These are the deductions the statute recognizes.¹ Federal and state income taxes are not on the list. Only FICA and the two local city taxes come off the top.

Protection for Low-Income Parents

New York shields parents at the bottom of the income scale from orders that would leave them unable to cover their own basic needs. In 2025, the self-support reserve was $21,128. A parent earning less than the federal poverty guideline may receive a “poverty order” of $25 per month. A parent above the poverty line but below the self-support reserve, or whose calculated obligation would push them below it, may receive a minimum order of $50 per month.³ These figures adjust periodically.

When the Court Deviates from the Formula

The CSSA number is presumptive, not fixed. A judge can move off the formula after weighing statutory factors that include each parent’s overall financial resources, the child’s physical and emotional health or special needs, the standard of living the child would have had in an intact household, tax consequences, non-monetary contributions to the child’s care, large gaps between the parents’ gross incomes, needs of other children the non-custodial parent supports, and extraordinary visitation expenses. The court has to explain on the record why it deviated and which factors drove the decision.¹ In practice, the most common reasons are a wide income disparity between the households and children with medical or educational needs the base formula doesn’t cover.

Imputed Income

A parent who quits or takes a lower-paying job to shrink a support obligation rarely succeeds. Courts can impute income, assigning an earning capacity based on the parent’s education, work history, skills, and local job market rather than the current paycheck. The imputed figure has to be supported by evidence like prior tax returns, professional credentials, and whether the parent actually looked for work that matched their qualifications.

Filing for Child Support

You start by filing a petition in Family Court in the county where the child lives with the custodial parent.⁴ There is no filing fee. The court issues a summons, the other parent has to be served, and the court can put a temporary order in place while the case moves forward so the child isn’t left without support in the meantime. If the other parent is served properly and doesn’t appear, the court can enter a default order on the information you provided, and that order is fully enforceable.

Financial Disclosure

Both parents file a sworn Financial Disclosure Affirmation.⁵ The form asks for income from all sources, monthly expenses, and every asset and liability. It has to be filed with the most recent federal and state tax returns, the W-2s that went with them, and a current paycheck stub.⁶ Only the most recent return is mandatory. Because the disclosure is sworn, false or incomplete information can carry serious consequences. If you want the court to factor in specific costs like private school tuition or ongoing medical bills, bring the documentation with you.

Enforcement When Payments Stop

New York enforces support orders aggressively, mostly through the Support Collection Unit in each social services district. The SCU’s core tool is income withholding: it sends an order to the paying parent’s employer requiring automatic deductions from each paycheck.⁷

When arrears build up, enforcement escalates. Once a parent falls four months behind, the court can direct the DMV to suspend their driver’s license. Professional and business license applicants must certify their support status, and a parent four or more months behind may receive only a six-month temporary license unless they get on a repayment plan or clear the arrears.⁸ The federal Treasury Offset Program intercepts tax refunds and redirects them toward past-due support.⁹ A parent who willfully refuses to pay despite clear ability can be held in contempt of court, with fines or jail time as possible outcomes. These tools stack: wage withholding, a suspended license, and an intercepted refund can all apply to the same case.

Modifying an Order

Support orders change with circumstances. New York allows modification on three grounds:

A substantial change in circumstances, such as job loss, serious illness, a child developing costly medical needs, or a significant jump in the paying parent’s income
Three years have passed since the order was entered or last modified
Either parent’s gross income has changed by 15% or more since the order was entered or last modified

The three-year and 15% grounds are automatic triggers for a review. A drop in income counts only if it was involuntary and the parent genuinely tried to find comparable work. Parents can opt out of the three-year and 15% triggers in a written agreement, in which case only the substantial-change standard applies.¹⁰ You file the modification petition in the same Family Court that issued the original order. The existing order remains in force until a new one is signed, and any arrears that pile up during the process are enforceable, so filing quickly when things change matters.

Taxes on Child Support

Child support has no tax consequences for either parent. The paying parent can’t deduct it; the receiving parent doesn’t report it as income.¹¹ The child tax credit and dependency exemption are a separate question. The custodial parent generally claims the child because the child lives with them for more than half the year, and the non-custodial parent can claim the child only if the custodial parent signs IRS Form 8332 releasing the exemption. Paying support does not by itself give a parent the right to claim the child.¹²
