Frequently Asked Questions
How is child support calculated in New York?
Step 1: Combine both parents' income. Step 2: Apply CSSA percentage (17% for 1 child, 25% for 2, etc.). Step 3: Multiply by non-custodial parent's percentage of combined income. Step 4: Add pro-rata shares of childcare and healthcare costs. Above $163,000 combined income, the court has discretion.
What is the NY CSSA income cap?

Can child support be modified in New York?
Yes, either parent can petition for modification if: (1) there's a substantial change in circumstances, (2) 3 years have passed since the last order, or (3) income has changed by 15%+ since the last order. File with family court or through the Support Collection Unit.
Does child support cover college in New York?
New York courts can order parents to contribute to college costs. Unlike child support (which typically ends at 21 in NY), college contribution is discretionary and considers: the child's academic ability, family financial resources, and the cost of education. There's no automatic formula for college.
Is child support taxable in New York?
No. Child support is not taxable income for the receiving parent and not deductible by the paying parent — for both federal and NY state purposes. This changed with the 2017 Tax Cuts and Jobs Act (previously, alimony was deductible/taxable, which affected related negotiations).
