What’s the difference between SSDI and SSI?

SSDI and SSI are both federal disability programs run by the Social Security Administration, but they work very differently.

SSDI is an insurance program. You earn coverage by working and paying FICA taxes. To qualify you need enough work credits (see our separate FAQ) and a medical condition that meets SSA standards under 42 U.S.C. §423(d). Your monthly benefit is calculated from your lifetime earnings record — there is no income or asset cap. After 24 months on SSDI you automatically receive Medicare.

SSI is a welfare program funded by general tax revenue, not your payroll taxes. Anyone who is aged, blind, or disabled and has limited income and resources can apply — even people who never worked. The 2026 federal benefit rate is $967/month for an individual and $1,450/month for a couple. States like New York add a small supplement on top. SSI recipients usually qualify for Medicaid immediately.

Many people qualify for both programs at the same time — called ‘concurrent benefits.’ This often happens when your SSDI amount is low. SSA offsets the payments so you do not receive both in full.

The medical rules are identical for both programs. SSA uses the same five-step sequential evaluation and the same Blue Book listings. Our team handles both SSDI and SSI claims — hablamos español and serve clients across New York. No fee unless we win.
