How Child Support Works in New York

New York uses the Child Support Standards Act (CSSA), which applies a fixed percentage of combined parental income to determine basic child support. The amount is then divided proportionally based on each parent’s share of income.

CSSA Percentages:

  • 1 child – 17%

  • 2 children – 25%

  • 3 children – 29%

  • 4 children – 31%

  • 5 or more – at least 35%

These percentages apply to combined income up to a statutory cap (adjusted annually; approx. $163,000 in 2024). For income above the cap, courts may use discretion.

Add-On Expenses in New York

Besides basic support, courts may order parents to share these expenses proportionally:

✅ Mandatory Add-ons:

  • Health insurance premiums for the child

  • Unreimbursed medical expenses

✅ Discretionary Add-ons:

  • Childcare costs (while a parent works or attends school)

  • Educational expenses (private school, tutoring, college)

  • Extracurricular activities (sports, music, etc.)

Parenting Time & Support Adjustments

While New York doesn’t reduce child support simply for joint custody, courts may consider parenting time in rare cases where the noncustodial parent provides substantially equal time and support. The primary residence parent generally receives support.
