New York SSDI & Child Support Calculator 2026 — How Disability Affects Your Obligation

In New York, SSDI payments count as income under FCA §413 / Dom. Rel. Law §240, and SSDI auxiliary benefits paid by the SSA to your dependent children are credited dollar-for-dollar against your child support obligation — if the auxiliary benefit equals or exceeds the guideline amount, you owe no direct payment.

In New York, Social Security Disability Insurance (SSDI) payments are treated as income for child support purposes under FCA §413 / Dom. Rel. Law §240. This means if you receive SSDI, your monthly benefit amount is included in the income figure used to calculate your child support obligation — the same as wages or salary would be. Supplemental Security Income (SSI), however, is excluded from child support income in New York because it is a needs-based federal benefit not intended to support others.

If you are currently paying child support in New York and you become disabled, your SSDI award is a material change in circumstances that may justify modifying your support order. You must file a petition for modification in the New York court that issued your original order — disability alone does not automatically reduce your obligation. Courts will consider your new SSDI income, the auxiliary benefit being paid to the children, and the custodial parent's income when setting the new amount. Petition promptly: modifications are typically only retroactive to the date you filed.

Frequently Asked Questions

Does SSDI count as income for child support in New York?
Yes. New York courts include SSDI in child support income calculations under FCA §413 / Dom. Rel. Law §240. The monthly SSDI benefit amount is treated like wages and used in the formula to calculate your obligation. SSI is excluded because it is a needs-based federal benefit.
How does the SSDI auxiliary benefit affect my New York child support?
The auxiliary benefit paid by the SSA to your dependent children is credited against your child support obligation in New York. If the auxiliary benefit equals or exceeds the guideline child support amount, you owe no direct payment. If it is less than the guideline, you pay only the remaining difference.
Can I modify my New York child support order after becoming disabled?
Yes — but you must file a petition for modification in the New York court that issued your order. Your disability and reduced income are a substantial change in circumstances justifying modification. The court will recalculate support based on your current SSDI income and any auxiliary benefits. File as soon as possible — courts generally modify prospectively from the petition date.
What is the SSDI auxiliary benefit amount I can expect?
The SSDI dependent child auxiliary benefit is approximately 50% of your Primary Insurance Amount (PIA) — your base monthly SSDI benefit. If you receive $1,600/month in SSDI, each qualifying child's auxiliary benefit is approximately $800/month. The total family benefit is capped at 150–180% of your PIA. Contact Social Security (1-800-772-1213) to get your specific benefit projection.
What if my SSDI benefit is less than the child support guideline in New York?
If your SSDI benefit (plus any auxiliary benefits paid to the child) does not cover the full guideline amount, you are still responsible for the difference. For example, if the New York guideline is $800/month and the auxiliary benefit is $600/month, you owe $200/month directly. The court will set your obligation accordingly upon your petition for modification.
Does SSI affect child support in New York?
No. SSI is excluded from child support income in New York because it is a federal needs-based benefit not intended to support others (42 U.S.C. §1383(d)). Only SSDI — which is earned through work history and FICA contributions — counts as income for New York child support purposes under FCA §413 / Dom. Rel. Law §240.
