Disability benefits are federal programs, but states shape how much you receive and what you can earn

Social Security Disability Insurance (SSDI) and Supplemental Security Income (SSI) are both federal programs run by the Social Security Administration. The federal government sets the basic rules: who can receive benefits, how long you must be disabled, what medical evidence you need, and the minimum payment amounts. But your state can and does change the actual dollar amount you receive, the rules about what you can earn while collecting, and whether you can access certain work incentives.

This split between federal control and state variation is why two people with the same disability and work history can receive different monthly payments depending on where they live. Understanding which rules are federal and which are state-controlled matters because it changes what you can negotiate, where you appeal, and whether moving to another state would change your payment.

Key Takeaways

  • SSDI is entirely federal; SSI is federal but states can add their own money on top, which changes your payment amount.
  • The federal government sets the basic payment amount for both programs each January, but some states increase SSI payments with state supplements.
  • Federal law controls whether you can work and earn money, but some states have stricter or more generous work incentive programs that affect what you keep.
  • If you disagree with a decision about your benefits, you appeal to a federal administrative law judge, not your state.
  • Your state of residence at the time you explore affects your SSI payment amount for the rest of your case, even if you move later.

How SSDI is purely federal, and SSI is federal with state add-ons

SSDI is a federal insurance program. You receive it because you or a family member paid Social Security taxes while working. The federal government collects those taxes, holds them in a trust fund, and pays out SSDI from that fund. Every SSDI recipient in the country receives the same federal payment for the same work history and disability status, regardless of state.

SSI is different. It is a federal needs-based program, but the federal government does not have to pay the full amount. The federal government pays a base amount (called the Federal Benefit Rate, or FBR), which is the same nationwide. But 29 states and Washington D.C. add their own money on top — called a state supplement. If you live in one of those states, your SSI check is larger than the federal base. If you live in a state with no supplement, you receive only the federal amount. If you move from a state with a supplement to one without, your payment drops.

The federal government also allows states to set their own rules about what counts as income and resources for SSI purposes. A few states use slightly different thresholds than the federal standard, which can affect whether you remain SSI-may be able to access at all.

Federal law controls work and earnings, but state programs shape what you keep

The federal government decides that SSDI and SSI recipients can work and earn money without losing all their benefits. Federal law created the Substantial Gainful Activity (SGA) threshold — a monthly earnings limit that changes each year. In 2024, SGA is $1,550 per month for non-blind workers. If you earn more than that, the federal government considers you no longer disabled and can stop your benefits.

But the federal government also created work incentives — rules that let you earn money and keep some or all of your benefits for a time. These include the Trial Work Period (nine months where you can earn any amount without losing SSDI), the Extended may be able to access Period (36 months where you can earn above SGA and keep SSDI if you report it), and Impairment Related Work Expenses (IRWE), which let you deduct disability-related costs from your earnings.

States can and do run their own programs on top of these federal incentives. Some states fund Medicaid Buy-In programs, which let you keep Medicaid even if your earnings are too high under federal rules. Some states fund Plans to Achieve Self-Support (PASS) programs with state money, which can be more generous than the federal version. If you live in a state that funds these programs, you have more options to work and earn than someone in a state that does not.

The federal government sets the base payment, but your state residence determines your actual check

Every January, the federal government announces a Cost of Living Adjustment (COLA) and applies it to all SSDI payments nationwide. This is a federal decision that affects every recipient the same way. For SSI, the federal government announces a new Federal Benefit Rate each January, and that is the base payment everyone receives.

But if you receive SSI and live in a state with a supplement, your state adds money to that federal base. The supplement amount varies widely by state. As of 2024, some states add less than $50 per month, while others add more than $200. Your state of residence when you are approved for SSI locks in which supplement rate applies to you. If you move to a different state, your supplement changes to match your new state's rules, effective the month you move.

SSDI has no state variation in the payment itself, but some states offer state-funded programs that give you cash or services on top of your SSDI check. These are rare and usually limited to people with very low income.

Appeals and disputes go to federal courts, not state agencies

If the Social Security Administration denies your claim or stops your benefits, you appeal to a federal administrative law judge, not your state. The entire appeals process — initial reconsideration, hearing before an administrative law judge, Appeals Council review, and federal court — is federal. Your state has no role in deciding whether you are disabled or whether you should receive benefits.

This means that if you disagree with a decision, you cannot appeal to your state's disability office or ask your state legislature to overturn it. You must follow the federal appeals process, which typically takes one to three years from initial denial to a hearing decision.

The only exception is if your dispute is about a state supplement to SSI. If you believe your state is not paying you the correct supplement amount, you can file a complaint with your state's Social Security office or contact your state's protection and advocacy agency. But disputes about whether you are disabled or whether you meet federal SSI rules go to federal court.

Medicaid and Medicare are federal, but Medicaid rules vary by state

Both SSDI and SSI recipients can receive health insurance, but the programs work differently. SSDI recipients receive Medicare after 24 months of receiving SSDI. Medicare is entirely federal — the same coverage, the same premiums, the same rules in every state.

SSI recipients receive Medicaid, which is federal money but state-administered. Every state must cover SSI recipients, but states can choose to cover additional people and can set different rules about what services are covered. This means your Medicaid coverage in one state might be broader than in another state. If you move from a state with generous Medicaid to one with narrower coverage, you may lose access to services you were using.

Some people receive both SSDI and SSI (called "concurrent" benefits). They receive Medicare from SSDI and Medicaid from SSI. In this case, Medicare is federal and Medicaid varies by state.

Your state of residence matters for SSI, but not for SSDI may be able to access

For SSDI, your state does not affect whether you are found disabled. The same medical standards explore everywhere. A condition that qualifies you in one state qualifies you in all states.

For SSI, your state of residence at the time you explore affects your payment amount for the life of your case. It also affects whether you meet the resource limit. A few states have slightly higher resource limits than the federal standard, which can mean the difference between being SSI-may be able to access and not. If you are planning to move and you are close to the SSI resource limit, moving to a state with a higher limit could keep you may be able to access.

Your state also affects your access to state-funded work incentive programs and Medicaid coverage. If you are working or planning to work, it is worth researching whether your state offers Medicaid Buy-In or other programs that could help you keep benefits while earning.

Frequently Asked Questions

If I move to a different state, will my SSDI payment change?

No. SSDI is entirely federal, so your payment stays the same no matter where you live. However, your access to state-funded programs and your Medicaid coverage may change. If you receive SSI along with SSDI, your SSI payment will change to match your new state's supplement rate.

Can my state deny me benefits if the federal government approved me?

No. Once the federal Social Security Administration approves you for SSDI or SSI, your state cannot override that decision. Your state administers some programs related to your benefits, but it cannot take away federal benefits you have been approved for.

Why is my SSI payment different from my friend's if we both live in the same state?

If you both receive SSI in the same state, your base federal payment should be the same, and your state supplement should be the same. The difference is likely because one of you has unearned income (like child support or a pension), or one of you has resources that reduce the payment. Ask your local Social Security office to explain the difference.

Does my state control whether I can use the Trial Work Period?

No. The Trial Work Period is a federal work incentive that applies everywhere. Your state cannot take it away or change how it works. However, your state may offer additional work incentive programs on top of the federal ones.

If I appeal a benefits decision, which government do I contact?

You contact the federal Social Security Administration and follow the federal appeals process. Your state has no role in deciding whether you are disabled or whether you should receive benefits. The appeal goes to a federal administrative law judge, not a state court.
