State SSI supplements — extra monthly payments
Most states pay a state supplement on top of the federal SSI benefit; California, New York, Massachusetts, and New Jersey pay some of the highest supplements, while a handful of states pay no supplement at all.
State supplements can add anywhere from a few dollars to several hundred dollars per month. Some states administer their own supplement; others let SSA administer it and combine it with the federal check. Ask your local SSA office or state Medicaid agency for the exact amount for your living arrangement.

Where does this rule live in SSA's regulations?
SSA publishes the SSI eligibility rules in the SSI Eligibility page on ssa.gov and the annual 2026 SSI figures at ssa.gov/oact/cola/SSI.html. When SSA's public page and this article differ, ssa.gov controls.
What if I'm not sure I qualify?
Apply anyway. SSA determines eligibility on the facts of your case, and application itself protects the earliest possible filing date. There is no penalty for applying and being denied.
