Social Security’s 2026 guide to SSI lists three kinds of states when it comes to the extra money some states add to the federal check. In California, Hawaii, Montana, Nevada, New Jersey and Vermont, Social Security itself pays the state supplement. In 33 states the state pays and runs its own. And Arizona, Arkansas, Mississippi, North Dakota, Tennessee and West Virginia add nothing at all.

The split decides who a recipient has to call when the total looks wrong. A person in a Social Security-run state can ask the agency about the whole payment. A person in a state-run program has to go to the state for the supplement, because Social Security only handles the federal part.

Which side a recipient falls on also changes what the check can be worth. A state that adds money raises the total above the federal $994 for one person in 2026. A state that adds nothing leaves it there. The agency’s SSI benefits guide carries the list, and the first question for anyone who moves is which column the new state sits in.

Six states where Social Security pays the supplement

The guide names California, Hawaii, Montana, Nevada, New Jersey and Vermont as places where Social Security administers the state supplement. For people in those states, the state money comes from the same office as the federal check. The agency tells them to contact it about the total benefit amount.

Six more jurisdictions split the job. Delaware, Iowa, Michigan, Pennsylvania, Rhode Island and the District of Columbia are marked as dual administration, where Social Security pays some categories of the state supplement and the state pays others.

Everywhere else: 33 state programs and six places with none

Read across the guide’s tables, the picture is simple. Social Security has a hand in the supplement in 12 jurisdictions, six of them alone and six sharing the job with the state. The state runs its own program with no help from the agency in 33. Seven places, six states and the Northern Mariana Islands, have no supplement.

In the third group, the state pays and administers its supplement without Social Security. The guide lists Alabama, Alaska, Colorado, Connecticut, Florida, Georgia, Idaho, Illinois, Indiana, Kansas, Kentucky, Louisiana, Maine, Maryland, Massachusetts, Minnesota, Missouri, Nebraska, New Hampshire, New Mexico, New York, North Carolina, Ohio, Oklahoma, Oregon, South Carolina, South Dakota, Texas, Utah, Virginia, Washington, Wisconsin and Wyoming.

For these states, the guide’s instruction is to contact the state for payment information. A recipient who gets a letter about the state money from the state, and a separate letter about the federal check from Social Security, is seeing the two programs run apart.

The no-supplement list is Arizona, Arkansas, Mississippi, North Dakota, Tennessee and West Virginia, along with the Northern Mariana Islands. In those places the federal check is the whole payment. Social Security says the maximum is $994 for an individual and $1,491 for a couple in 2026.

The guide also notes a separate section on SSI for children, which covers states that supplement benefits for children.

What a supplement does to the check

The agency says the extra money from a state does not reduce SSI. Some states pay an extra amount toward food and shelter costs, and that payment is added on top. In Social Security’s worked examples, a recipient living alone with a $300 Social Security check gets $714 in federal SSI, and a $15 state supplement lifts the total to $729.

A working recipient sees the same effect. With $317 in wages, the federal payment in that example is $878, and the $15 supplement makes it $893. The state amount in the example is only an illustration. Real supplements vary with income, living arrangement and other factors, the guide says.

The practical result is that two recipients with identical income can have different totals only because of where they live. Someone in Mississippi with a $300 Social Security check would get $714. The same person in a state that pays the $15 example amount would get $729, and in a state that pays more, the total is higher still.

Which office to call

The guide gives a short rule for each group. In a state where Social Security administers the supplement, the agency can answer questions about the total benefit amount. In a state-run program, the guide says to contact the state for payment information. In the dual states, the answer depends on which category of supplement a recipient gets.

The list names who runs each program. It does not give the supplement amounts, and it does not say how many recipients get each kind of payment. Those figures come from the states’ own rules, which the agency leaves to the states.

The dual states deserve a second look. A recipient in Michigan or Pennsylvania may find that one category of state money arrives through Social Security and another through the state. The guide marks those states with an asterisk and does not say which categories fall on which side.

That leaves one question for every recipient: which column the home state sits in. A person in Hawaii or New Jersey calls Social Security. A person in Texas or Ohio calls the state. A person in Arizona has no state supplement to ask about, and the $994 federal figure for 2026 is the whole payment.

Which office pays the state add-on to SSI?

The risk is calling the wrong office. In a state-run program, the supplement is the state’s to answer for, and a question about it sent to Social Security can go nowhere while the total on the deposit stays wrong.

The SSI & Disability Action Kit lists the 2026 SSI income and resource limits in a 74-page guide, with review and reporting steps and a section of contacts for the offices a recipient needs, so a move or a change gets reported to the right place.
