You cannot receive the full benefit amount from both programs simultaneously, but you may receive a partial SSI payment alongside SSDI under specific circumstances.

Social Security Disability Insurance (SSDI) and Supplemental Security Income (SSI) are separate programs with different rules about how they interact. If you receive SSDI, Social Security will count that income when calculating your SSI payment. In most cases, your SSDI amount will be high enough that you do not may have access to for SSI. However, if your SSDI payment falls below your state's SSI limit, you may receive a small SSI top-up payment to bring your total to the minimum threshold.

The key difference is that SSDI is based on your work history and contributions to Social Security, while SSI is a needs-based program for people with limited income and resources. Because SSI counts other income against it, receiving SSDI typically reduces or eliminates your SSI payment rather than stacking on top of it.

Key Takeaways

  • If your SSDI payment is below your state's SSI limit, you may receive a partial SSI payment called a "deemed" or "federal benefit rate" top-up.
  • Social Security counts your SSDI income dollar-for-dollar when calculating SSI, so higher SSDI payments mean lower or no SSI payment.
  • Your state's SSI limit varies; some states add extra money on top of the federal amount, which changes your may be able to access for the top-up.
  • You must meet SSI's resource limits (typically $2,000 for individuals) even if you receive SSDI, and SSDI does not count toward this resource limit.
  • If you were receiving SSI before you became may be able to access for SSDI, Social Security will automatically review your case to determine if you still may have access to for any SSI payment.

How Social Security counts SSDI income against SSI

When you receive SSDI, Social Security treats that payment as unearned income on your SSI case. The program subtracts your SSDI amount from the SSI federal benefit rate (the base payment amount set by federal law each year) to determine what, if anything, you receive in SSI.

For 2024, the federal SSI benefit rate is $943 per month for an individual. If your SSDI payment is $800, Social Security would subtract that from $943, leaving $143 that you could potentially receive in SSI. However, your state may have its own SSI supplement that raises the total limit. If your state adds a supplement, the calculation uses the higher state limit instead of the federal amount.

This means the relationship between your two payments depends entirely on how much SSDI you receive. A higher SSDI payment reduces your SSI payment proportionally, and if your SSDI meets or exceeds your state's SSI limit, you receive no SSI at all.

When you might receive both payments

You are most likely to receive both SSDI and SSI if you worked very little before becoming disabled, so your SSDI payment is small. This can happen if you became disabled young, worked only briefly, or had low earnings during your working years. In these situations, your SSDI might be $400 or $500 per month, which leaves room for an SSI top-up payment.

You may also receive both if you transition from SSI to SSDI. If you were already on SSI and then become may be able to access for SSDI (for example, because you reached retirement age and your case converted, or because you worked enough quarters to may have access to), Social Security automatically recalculates your SSI. The agency will determine whether you still may have access to for any SSI payment based on your new SSDI amount.

Another scenario involves deemed income. If you are under 18 or in certain other situations, Social Security may "deem" part of your parents' or spouse's income to you for SSI purposes. This deemed income is added to your SSDI when calculating your SSI payment, which can reduce or eliminate your SSI even if your SSDI alone would have may have access to you for a top-up.

Resource limits and how they apply to both programs

SSI has strict resource limits: you can own no more than $2,000 in countable resources as an individual (or $3,000 if you are married and both receive SSI). SSDI has no resource limit, so you can own as much as you want and still receive SSDI. However, if you receive even a small SSI payment, you must stay under the SSI resource limit.

Certain resources do not count toward the limit, such as your primary home, one vehicle, household goods, and life insurance with a face value under $1,500. Your SSDI payment itself does not count as a resource once you receive it, but money in your bank account does. If you are trying to stay under the resource limit while receiving both payments, you need to track your savings carefully and understand which assets count.

If your resources exceed the SSI limit, you lose SSI may be able to access entirely, even if you would otherwise may have access to for a top-up payment. You would continue to receive SSDI, but the SSI portion would stop. Once your resources drop back below the limit, you can request that SSI be reinstated.

How state SSI supplements affect your payment

Twenty-three states and the District of Columbia provide their own SSI supplement on top of the federal benefit rate. These supplements raise the total SSI limit in those states, which changes how much SSDI you can receive before your SSI payment disappears entirely.

For example, if your state has a $100 monthly supplement, the SSI limit in your state is $1,043 instead of $943. If your SSDI is $900, you would receive $143 in SSI in a state without a supplement, but $143 in SSI in a state with a supplement (because the limit is higher). The supplement does not give you extra money on top of SSDI; it only raises the threshold at which you stop may have access to for SSI.

Some states also have "optional" supplements for certain groups, such as people living in their own home or in a group living situation. These vary by state and can affect your calculation. You can contact your state's SSI program or call Social Security to find out whether your state has a supplement and how it applies to your situation.

What happens if your SSDI amount changes

If your SSDI payment increases or decreases, Social Security will automatically recalculate your SSI. If your SSDI goes up, your SSI will go down by the same amount (or disappear entirely if the increase pushes you over your state's limit). If your SSDI goes down, your SSI will increase to compensate, as long as you still meet all other SSI requirements.

You do not need to report SSDI changes to SSI; Social Security handles this internally. However, you should keep track of your total monthly payment to make sure it matches what you expect. If you notice an unexpected change, contact Social Security to ask why your payment was adjusted.

Cost-of-living adjustments (COLAs) affect both SSDI and SSI. When Social Security announces an annual COLA, both your SSDI and SSI payments increase by the same percentage. This means your SSI top-up payment may also increase slightly, though the increase is usually small.

Work incentives and how they interact with both programs

If you work while receiving SSDI and SSI, both programs have work incentives that allow you to earn money without losing all your benefits. However, the rules are different for each program, and you must follow both sets of rules simultaneously.

SSDI has the Plan to Achieve Self-Support (PASS) and Impairment Related Work Expenses (IRWE), which allow you to set aside income and expenses without affecting your SSDI. SSI has its own work incentive rules, including a $65 monthly exclusion plus 75 percent of remaining earnings. If you receive both, you must track your earnings under both programs' rules, and your SSI payment will be reduced based on SSI's calculation, not SSDI's.

Work incentives can be complex when you receive both programs. A work incentives planning and assistance (WIPA) project or Protection and Advocacy for Beneficiaries of Social Security (PABSS) program can help you understand how your earnings will affect both payments. These services are free and available in every state.

Frequently Asked Questions

If I get SSDI, do I automatically get SSI too?

No. Social Security will review your case to see if you may have access to for SSI based on your SSDI amount and your resources, but you do not automatically receive both. If your SSDI payment is high enough or your resources are too high, you will receive only SSDI.

Can I have more than $2,000 in savings if I receive SSDI and SSI?

No. The $2,000 resource limit applies to SSI, and if you receive any SSI payment, you must stay under that limit. SSDI has no resource limit, but the SSI portion of your case does. If your resources exceed $2,000, you lose SSI but keep SSDI.

What if my SSDI payment is $1,000 but my state's SSI limit is $943?

You would receive only SSDI. Social Security would subtract your $1,000 SSDI from the $943 SSI limit, which results in no SSI payment. You would receive the full $1,000 SSDI and nothing from SSI.

Do I need to report my SSDI to SSI, or does Social Security do it automatically?

Social Security does it automatically. The agency shares information between SSDI and SSI internally, so you do not need to report your SSDI payment to your SSI case. However, you should review your payment statement to make sure the amounts are correct.

If I work and earn money, how does it affect both SSDI and SSI?

Each program has its own rules for how earnings reduce your payment. SSI counts most of your earnings against your benefit, while SSDI allows more earnings before your payment is affected. If you receive both, your SSI payment will be reduced based on SSI's earnings rules, which are stricter than SSDI's.
