How New York Child Support Works in 2026

New York calculates child support under the Child Support Standards Act (CSSA), codified in Domestic Relations Law §240(1-b) for matrimonial actions and Family Court Act §413 for non-matrimonial cases. The formula applies fixed percentages to combined parental income up to a statutory cap.

The CSSA Percentages

2026 Combined Income Cap — $193,000

Effective March 1, 2026, the CSSA cap rose to $193,000 in combined parental income (up from $183,000 since March 2024). The cap adjusts biennially by Consumer Price Index. For combined income above the cap, courts have discretion (not obligation) to apply CSSA percentages to the excess — they may also award lower amounts based on the children's actual needs and §240(1-b)(f) factors.

CSSA Cap History

Self-Support Reserve (SSR) — $21,546 in 2026

Under DRL §240(1-b)(d), courts must ensure a child support order does not reduce the payor's income below the Self-Support Reserve — set at 135% of the federal poverty level for a single person. For 2026, SSR = $21,546/yr. Orders that would drop the payor below SSR are capped or reduced to protect subsistence.

Step 1: Combined Income = NCP Income + Custodial Income (capped at $193,000)
Step 2: Basic Support = Combined Income × CSSA %
Step 3: NCP Obligation = Basic Support × (NCP Income / Combined Income)
Step 4: Verify NCP Net After Support ≥ Self-Support Reserve ($21,546/yr)
Step 5: Add pro-rata share of childcare, medical, and educational add-ons

Add-Ons (Separate from Basic Percentage)

Worked Example — 2026

NCP earns $100,000/yr. Custodial parent earns $60,000/yr. Two children.

Legislative Watch

Bills A8389-A / S8431 are pending in the 2025–2026 legislative session proposing structural changes to CSSA percentages (particularly for higher income brackets and shared-custody formulas). Neither bill has been enacted as of April 2026. We monitor and update this calculator when new law takes effect.

Frequently Asked Questions

Effective March 1, 2026, the CSSA cap is $193,000 in combined parental income (up from $183,000). The cap adjusts biennially per Consumer Price Index (CPI) via the Office of Temporary and Disability Assistance. For combined income above $193,000, courts exercise discretion under DRL §240(1-b)(f) — they may apply CSSA percentages to all income, some, or none. Next review: March 2028.
The 2026 Self-Support Reserve is $21,546/yr (135% of the federal poverty level for a single person). Courts must ensure a support order does not reduce the payor's net income below this floor. If guideline support would violate SSR, the order is reduced. This protects low-income payors from being pushed into destitution while still requiring contribution to their children's support.
No. Above $193,000 combined income, courts have full discretion under §240(1-b)(f). They may: (1) apply CSSA percentages to all income, (2) apply to income above the cap only if children's needs justify it, or (3) set a fixed dollar amount. The 10 statutory factors include children's lifestyle, each parent's resources, educational needs, and tax consequences. Many courts apply CSSA up to ~$350–500K combined, above which discretion rules.
Add-ons are calculated separately from the basic CSSA percentage and allocated pro-rata by income share (not 50/50). For example, if NCP earns 62.5% of combined income and childcare is $1,000/mo, NCP's share is $625/mo on top of the basic obligation. Statutory add-ons include: work-related childcare, unreimbursed medical/dental, children's portion of health insurance premiums, and — at court discretion — educational expenses.
Under DRL §240(1-b)(b)(5), income includes: gross wages, investment income, pensions, veterans' benefits, workers' compensation, unemployment benefits, Social Security benefits, disability benefits, and fringe benefits. Deductions allowed: FICA, Medicare, NYC/Yonkers income tax, maintenance/alimony paid, other support orders, union dues, and mandatory retirement. The result is "CSSA income" used in the formula.

When to Consult a New York Family Law Attorney

NY CSSA is deceptively simple — the 17/25/29/31/35 percentages are easy, but above-the-cap discretion, Self-Support Reserve limits, and add-on allocation create complexity. Consult a licensed NY attorney if your case involves: combined income above $193,000 (cap discretion), imputed income (self-employed, cash businesses), significant non-wage income (investment, trust distributions), interstate jurisdiction (UIFSA issues), or modification requests. The Appellate Divisions have nuanced case law on each CSSA factor.
