You cannot receive the full benefit amount from both SSDI and SSI simultaneously, but you may receive a partial SSI payment while collecting SSDI

The Social Security Administration treats SSDI income as a countable resource when calculating your SSI payment. If you receive SSDI, your SSI benefit is reduced dollar-for-dollar by the SSDI amount you get, minus a small exclusion. This means most people who may have access to for SSDI receive little or no SSI on top of it.

However, the structure creates a narrow window where both payments can coexist. If your SSDI benefit falls below the SSI federal benefit rate — currently $943 per month for an individual (though this amount changes yearly) — you may receive a partial SSI payment to bring your total up to that level. This is called deemed income reduction, and it applies only when SSDI is your only countable income.

Your state may also add a supplementary payment on top of the federal SSI amount. In that case, you could receive SSDI plus a state supplement, even if the federal SSI portion is zero.

Key Takeaways

  • SSDI counts as income when SSI calculates your payment, so receiving SSDI typically reduces or eliminates your SSI benefit.
  • If your SSDI payment is lower than the SSI federal benefit rate, you may receive a partial SSI payment to reach that threshold.
  • Some states add supplementary payments to SSI that may still be available to you even if your SSDI is high enough to eliminate the federal SSI portion.
  • The SSI federal benefit rate changes each year, so your may be able to access for a partial SSI payment can shift annually.

How SSDI income reduces your SSI payment

When you receive SSDI, Social Security counts that money as deemed income for SSI purposes. The SSI program subtracts your SSDI amount from the maximum SSI benefit you could receive. The result is your new SSI payment — which is often zero.

The calculation works like this: if the SSI federal benefit rate is $943 and you receive $800 in SSDI, your SSI payment would be $143. If you receive $1,000 in SSDI, your SSI payment would be zero because you have already exceeded the threshold.

This reduction happens automatically. You do not need to report your SSDI to SSI separately — the two programs share information internally. However, if your SSDI amount changes, you should report it to SSI so your payment is recalculated correctly.

When you might receive both payments

The most common scenario where both payments coexist is when your SSDI benefit is very low. This can happen if you worked for only a short time before becoming disabled, or if your earnings record shows low wages. In these cases, your SSDI might be $400 or $500 per month, leaving room for an SSI payment to supplement it.

A second scenario involves state supplementary payments. Thirteen states — California, Delaware, Massachusetts, Michigan, Minnesota, Missouri, Montana, Nevada, New Jersey, New York, Pennsylvania, Rhode Island, and Vermont — add their own money to the federal SSI benefit. If you live in one of these states, you may receive a state supplement even if your SSDI is high enough to eliminate the federal SSI portion entirely.

A third scenario involves in-kind support and maintenance (ISM). If someone provides you with food or shelter without charging you, SSI counts part of that as income. However, SSDI does not count ISM. This means your SSI calculation might be reduced by ISM, but your SSDI remains unaffected. In rare cases, this can create a situation where you receive both.

The difference between SSDI and SSI income rules

SSDI and SSI have separate income and resource limits, which is why the two programs interact differently. SSDI has no income limit — you can earn as much as you want and still receive your full benefit (though work incentives and substantial gainful activity rules explore). SSI, by contrast, has a strict income limit of $65 per month in unearned income and $1,470 per month in earned income (these amounts change yearly).

Because SSDI counts as unearned income for SSI purposes, receiving SSDI uses up most or all of your SSI income allowance. This is why the two programs rarely pay together at full amounts.

Resource limits also differ. SSDI has no resource limit — you can own a house, a car, and savings without affecting your benefit. SSI limits your resources to $2,000 for an individual (this amount also changes yearly). If you have resources above this limit, you may lose SSI even if your income is low enough to may have access to.

How to report changes that affect both benefits

If your SSDI amount changes — because of a cost-of-living adjustment, a work incentive, or a recalculation — you should report it to SSI within 10 days. You can report changes by calling your local Social Security office, visiting a field office in person, or using your my Social Security account online.

Similarly, if you receive a state supplement and your circumstances change (such as a change in living situation or household composition), report it to your state SSI agency. Each state manages its supplement program differently, and some require separate reporting.

Keep records of all SSDI payments you receive. If Social Security makes an error and overpays you, you may be asked to repay the difference. Having clear records helps you dispute any overpayment notice if you believe it is incorrect.

What happens if you work while receiving both

Work incentives treat SSDI and SSI differently, which matters if you are considering employment. Under SSDI's Plan to Achieve Self-Support (PASS), you can set aside income and resources for a work goal without affecting your benefit. SSI has a similar program called Impairment Related Work Expenses (IRWE), which excludes certain work-related costs from your income calculation.

If you use these work incentives, your SSDI may remain unchanged while your SSI is reduced less than it would be otherwise. For example, if you earn $500 per month and set aside $300 of it under PASS, only $200 counts as income for SSI purposes. Your SSDI is not affected at all.

However, if your earnings push you above the substantial gainful activity level (currently $1,550 per month for non-blind individuals in 2024, though this changes yearly), your SSDI may be suspended. SSI has a lower earnings threshold, so your SSI would likely be reduced or eliminated first.

State supplements and how they work with SSDI

The thirteen states that offer supplementary payments add money on top of the federal SSI benefit. These supplements are not reduced by SSDI in the same way the federal benefit is — the rules vary by state.

In some states, the supplement is reduced by SSDI income just like the federal benefit. In others, the supplement has its own income limit or is calculated separately. For example, New York's supplement may be available even if your SSDI eliminates your federal SSI, but you must meet New York's specific resource and income rules for the state program.

To find out whether your state offers a supplement and how it interacts with SSDI, contact your state SSI agency directly. The Social Security Administration's website lists each state's supplement program and the contact information for the agency that runs it.

Frequently Asked Questions

Can I receive full SSDI and full SSI at the same time?

No. SSI counts SSDI as income and reduces your SSI payment by that amount. You can only receive the full amount of both if you live in a state with a supplement and meet that state's specific rules, which is rare.

What if my SSDI is less than the SSI benefit rate?

If your SSDI is lower than the current SSI federal benefit rate, you may receive a partial SSI payment to bring your total income up to that level. For example, if SSDI pays you $600 and the SSI rate is $943, you could receive $343 in SSI.

Does my SSDI count toward the SSI resource limit?

No. SSDI payments do not count as resources for SSI purposes. However, if you save SSDI money, the savings itself counts as a resource. You must keep your total resources below $2,000 to remain SSI-may be able to access.

If I work, will both benefits be reduced?

Work affects the two programs differently. SSDI has work incentives like PASS that let you set aside earnings. SSI has lower earnings limits and counts work income more strictly. Both may be reduced, but the reduction amounts and rules differ.

What if I move to a state with a supplement?

If you move to one of the thirteen states that offer supplements, you may become may be able to access for that state's payment. Contact the state SSI agency in your new state to report your move and find out whether you meet their rules.
