You cannot receive both SSI and SSDI payments simultaneously, but you may be able to receive one and then the other

Social Security has a rule called concurrent receipt that prevents you from collecting both Supplemental Security Income (SSI) and Social Security Disability Insurance (SSDI) in the same month. If you are found to be disabled under both programs' rules, Social Security will pay you whichever benefit is higher and stop the lower one. The payment you receive comes from only one program.

However, your situation can change. People move between SSI and SSDI as their circumstances shift — usually when work history builds up, when SSDI benefits start, or when SSI income limits are exceeded. Understanding how this transition works matters because the rules about how much you can earn, what counts as income, and what happens to your benefits are different in each program.

Key Takeaways

  • Social Security pays you the higher of the two benefits if you may have access to for both SSI and SSDI, never both amounts combined.
  • You can move from SSI to SSDI if you build enough work history, or from SSDI to SSI if your SSDI benefit drops below the SSI federal rate.
  • The programs count income differently: SSDI has no income limit, but SSI stops or reduces your payment if you earn over $65 per month (2024 figure, adjusted yearly).
  • If you receive SSDI and your benefit is less than the SSI federal rate, Social Security may pay you a small SSI top-up called deemed SSI.
  • Reporting changes in work, income, or living situation to Social Security is required under both programs to keep your payment correct.

How Social Security chooses which benefit to pay

When you meet the disability rules for both programs, Social Security compares the two monthly amounts and pays you the larger one. This is not a choice you make — it is automatic. The federal SSI rate for 2024 is $943 per month for an individual (this amount increases each year). If your SSDI benefit calculates to $1,200, you receive $1,200 from SSDI and nothing from SSI. If your SSDI benefit is $800, you would receive $800 from SSDI plus a small SSI top-up to bring you closer to the federal rate.

The top-up payment is called deemed SSI because Social Security counts you as receiving SSI for purposes of Medicaid and other benefits, even though most of your money comes from SSDI. This matters because it affects which health insurance you keep and what work incentives you can use. Deemed SSI is not a separate application — it happens automatically if you meet the rules.

Moving from SSI to SSDI when you build work history

Many people start on SSI because they have not worked enough to build SSDI may be able to access. As you work and pay Social Security taxes, you earn work credits toward SSDI. Once you have enough credits (usually 40 total, with 20 earned in the last 10 years), you become may be able to access for SSDI based on your own work record. At that point, Social Security will switch you to SSDI if the SSDI amount is higher than your SSI payment.

This transition can happen while you are still working under SSI's work incentives. The Plan to Achieve Self-Support (PASS) program lets you set aside income and resources to reach a work goal without losing SSI, and it can help you build the work history you need for SSDI. Once SSDI starts, PASS ends, but you move into SSDI's much more generous earnings rules — you can earn substantially more without losing your benefit.

Moving from SSDI to SSI when benefits drop

The reverse situation also happens. If your SSDI benefit is reduced — for example, because you reached full retirement age and your benefit was recalculated, or because a family member's benefit affected yours — it may fall below the SSI federal rate. When that occurs, Social Security can start paying you SSI to make up the difference, as long as you still meet SSI's other rules (income limits, resource limits, and living situation rules).

This transition is less common but matters if you are managing multiple benefits or if your household income changes. SSI has strict limits on how much money you can have in savings ($2,000 for an individual in 2024, adjusted yearly) and counts most types of income, whereas SSDI does not count most income against your benefit. If you move to SSI, you will need to track these limits more carefully.

How work and earnings affect each program differently

The earnings rules are the biggest practical difference between the two programs. Under SSDI, you can earn as much as you want without losing your benefit, though if you earn over a certain amount ($1,550 per month in 2024, adjusted yearly) Social Security may decide you are no longer disabled and stop your benefit after a trial work period. Under SSI, your benefit reduces by $1 for every $2 you earn over $65 per month, so earning more money directly shrinks your payment.

Both programs offer work incentives to help you test your ability to work without immediately losing coverage. SSDI has the Trial Work Period, which lets you work and earn any amount for nine months without affecting your benefit. SSI has the PASS program mentioned above. Understanding which incentives apply to your situation — and using them correctly — can mean the difference between building sustainable work and losing your benefits by accident.

What happens to Medicaid and Medicare when you switch programs

Your health insurance can change when you move between SSI and SSDI. SSI recipients typically receive Medicaid, which is run by your state and covers medical costs. SSDI recipients typically receive Medicare after 24 months of SSDI may be able to access, which is federal insurance. If you move from SSI to SSDI, you may lose Medicaid before Medicare starts, creating a gap. If you move from SSDI to SSI, you may gain Medicaid coverage again.

Some states have programs that let you keep Medicaid even after you move to SSDI, and some SSDI recipients can stay on Medicaid instead of switching to Medicare. The rules vary significantly by state. When Social Security notifies you of a benefit change, contact your state Medicaid office or your local Social Security office to confirm what insurance you will have and whether you need to take any action to keep coverage.

Reporting changes so your benefit stays correct

Both SSI and SSDI require you to report certain changes to Social Security within 10 days. These include starting or stopping work, a change in your living situation, a change in who lives with you, or a change in your income. Failing to report can result in overpayments that you may have to repay, or underpayments that you miss out on.

The easiest way to report is through your my Social Security account online, or by calling your local Social Security office. Keep records of your work and earnings, especially if you are using a work incentive like the Trial Work Period or PASS. Social Security's work incentives coordinators at your local office can help you understand what you need to report and when.

Frequently Asked Questions

If I am on SSI and start working, can I move to SSDI without losing my benefit?

Not automatically. You move to SSDI only when you have earned enough work credits through employment. While you are building those credits, SSI will reduce your payment based on your earnings. Once you have enough credits and your SSDI benefit is higher than your SSI payment, Social Security will switch you over. Using the PASS program can help you set aside some earnings so you keep more SSI while you work toward SSDI may be able to access.

What if my SSDI and SSI amounts are almost the same?

Social Security will pay you whichever is higher. If they are within a few dollars, you will receive the larger amount from one program only. You will not receive a combined payment or a small top-up unless your SSDI is significantly lower than the SSI federal rate, in which case you may receive deemed SSI.

Can I request to receive SSI instead of SSDI if SSDI pays more?

No. Social Security automatically pays the higher benefit. You cannot choose to receive the lower amount. However, if you have concerns about how your benefit was calculated, you can request a reconsideration or appeal through Social Security's standard review process.

Do I lose my health insurance if I switch from SSI to SSDI?

Possibly. SSI typically includes Medicaid, while SSDI includes Medicare after 24 months. If you move from SSI to SSDI, you may have a gap before Medicare starts. Some states have programs to keep you on Medicaid during the transition. Contact your state Medicaid office and your local Social Security office to understand your coverage before the switch happens.

What if I am on SSDI and my benefit gets reduced?

If your SSDI benefit drops below the SSI federal rate, Social Security may start paying you deemed SSI to bring your total payment up. This is automatic if you meet SSI's other rules. You will keep your SSDI health insurance (Medicare) and gain SSI's resource and income protections, though you will need to follow SSI's stricter earnings rules.
