Overview

Child support in New York is calculated using a specific formula established by the Child Support Standards Act (CSSA). Understanding how support is calculated, when it can be modified, and how it's enforced helps both custodial and non-custodial parents navigate this important obligation. This guide explains the rules that govern child support in New York.

The Basic CSSA Formula

New York calculates child support using the Child Support Standards Act formula:

Combined parental income: Both parents' gross income minus FICA taxes
Percentage applied based on number of children:
- 1 child: 17% of combined income
- 2 children: 25%
- 3 children: 29%
- 4 children: 31%
- 5+ children: 35% or more
Non-custodial parent's share: Their percentage of combined income × support amount
Income cap: Formula applies to combined income up to $163,000 (as of 2023, adjusted periodically)

Add-On Expenses

Beyond basic support, parents share certain additional expenses:

Childcare: Work-related childcare costs shared proportionally
Health insurance: Premium costs for children shared proportionally
Unreimbursed medical: Expenses not covered by insurance shared proportionally
Educational expenses: May be ordered in some cases
Extracurricular activities: Can be included by agreement or court order

Income Calculation

Understanding what counts as 'income' for child support purposes:

Gross income from all sources (wages, self-employment, investments)
Bonuses, commissions, and overtime typically included
Imputed income if voluntarily unemployed or underemployed
Social Security benefits, disability, workers' comp included
Deductions: FICA taxes, NYC taxes (if applicable), prior child support orders
Self-employed: Income calculated differently (business expenses scrutinized)

Modification of Support

Child support can be modified when circumstances change:

Either parent can petition to modify
Grounds: 15% change in income, 3 years since last order, or substantial change in circumstances
Modification is prospective (from date of filing), not retroactive
Job loss doesn't automatically reduce support—must file for modification
Incarceration: Recent law changes allow modification for incarceration over 180 days

Enforcement

New York has strong enforcement tools for unpaid child support:

Income withholding (wage garnishment) is standard
Tax refund interception (state and federal)
Suspension of driver's license
Suspension of professional licenses
Passport denial for arrears over $2,500
Contempt of court (potential jail time)
Credit reporting of arrears

Common Mistakes to Avoid

Knowing what NOT to do is just as important as knowing the right steps. Avoid these common errors.

Mistake: Making informal support arrangements without a court order

Consequence

Payments aren't legally credited, and you may owe 'back support' even if you paid informally.

Prevention

Always get court orders for child support, even if you and the other parent agree.

Mistake: Stopping payments without court permission

Consequence

Support arrears accumulate with interest, and enforcement actions can include jail.

Prevention

If circumstances change, file for modification BEFORE reducing or stopping payments.

Mistake: Not reporting income changes

Consequence

You may be paying too much or too little, neither of which is in anyone's interest.

Prevention

File for modification when income changes significantly (15% or more).

Mistake: Hiding income to reduce support

Consequence

Courts can impute income based on earning capacity and penalize deception.

Prevention

Be honest about income—courts have tools to discover hidden earnings.

Frequently Asked Questions

How is child support calculated in New York?

New York uses the Child Support Standards Act (CSSA) formula: a percentage of combined parental income (17% for 1 child, 25% for 2, 29% for 3, etc.) is calculated, then divided between parents based on their income shares. The non-custodial parent pays their share to the custodial parent. Add-on expenses like childcare and health insurance are shared proportionally.

Can child support be modified in New York?

Yes. You can petition for modification if: (1) either parent's income has changed by 15% or more, (2) 3 years have passed since the last order, or (3) there's been a substantial change in circumstances. Modification is prospective from the date you file—you can't get credit for past overpayments or reduce past arrears.

What happens if I don't pay child support?

New York has aggressive enforcement tools: automatic wage garnishment, tax refund interception, driver's license suspension, professional license suspension, passport denial, credit reporting, and contempt of court (which can include jail). Interest accrues on unpaid support. It's critical to file for modification if you can't pay rather than just stopping payments.

Does child support end at 18 in New York?

No. In New York, child support continues until age 21, not 18. Support can end earlier if the child becomes emancipated (through marriage, military service, or economic independence). Parents can also agree to extend support past 21 for college, but courts cannot order support past 21.

What if my ex hides income to reduce child support?

Courts can 'impute' income based on earning capacity if a parent is voluntarily unemployed or underemployed. Discovery tools can uncover hidden income through bank records, tax returns, and lifestyle analysis. If you suspect hidden income, document the other parent's lifestyle and assets, and work with an attorney to investigate.
