You cannot receive both SSI and SSDI payments at the same time, but you may be able to receive one and then switch to the other

Social Security has a rule called deeming that prevents you from collecting both Supplemental Security Income (SSI) and Social Security Disability Insurance (SSDI) in the same month. If you are approved for both programs, Social Security will pay you whichever benefit is larger and stop the smaller one. However, your situation may change over time—your SSDI amount might increase, or your SSI circumstances might shift—and you could move from one program to the other.

The reason for this rule is that both programs are meant to replace lost income due to disability. Social Security treats them as overlapping rather than stacked. Understanding how this works matters because it affects how much money you actually receive and what happens to your benefits if your income or living situation changes.

Key Takeaways

  • Social Security will pay you the larger of the two benefits if you are approved for both SSI and SSDI, not both amounts combined.
  • Your SSDI amount is based on your work history and the taxes you paid into Social Security; your SSI amount depends on your income and assets.
  • If your SSDI payment increases over time, you may eventually receive only SSDI and lose SSI entirely.
  • If your SSDI ends—for example, because you return to work—you may then become may be able to access for SSI if your income and assets are low enough.
  • You should report any changes in income, living situation, or work status to Social Security right away, because receiving the wrong benefit amount is considered an overpayment you may have to repay.

How Social Security decides which benefit you receive

When you are approved for both programs, a Social Security representative will calculate your SSDI amount first. This is based on your earnings record—how much you worked and how much you paid into Social Security over your lifetime. Your SSDI payment is the same whether you live alone, with family, or in a group home.

Next, Social Security calculates what your SSI payment would be. This amount depends on your living situation, your other income, and your assets. If you live with family members who support you, your SSI payment is reduced. If you have a job that pays even a small amount, your SSI payment is reduced further. If you own a home or have savings above certain limits, you may not may have access to for SSI at all.

Social Security then compares the two amounts. You receive whichever is larger. If your SSDI is $900 per month and your SSI would be $600 per month, you receive $900 SSDI and $0 SSI. If your SSDI is $500 and your SSI would be $700, you receive $700 SSI and $0 SSDI.

When your SSDI amount changes and affects your SSI

Your SSDI payment can increase if you reach your full retirement age. Social Security automatically recalculates your benefit at that point, and your payment typically goes up. If this increase pushes your SSDI above what your SSI would have been, Social Security will stop your SSI payments entirely. You will receive only SSDI from that point forward.

You will receive a notice in the mail when this happens. The notice will explain that your SSI has ended because your SSDI is now the larger benefit. This is not a penalty—it is how the system works. Your total monthly payment may stay the same, increase, or even decrease slightly depending on the exact amounts, but you will no longer receive two separate payments.

Cost-of-living adjustments (COLA) happen once per year, usually in January. Both your SSDI and SSI payments may increase, but the same rule applies: you receive only the larger amount. If your SSDI increases and becomes larger than your SSI, your SSI stops.

When your SSDI ends and you may may have access to for SSI instead

If you return to work and your earnings become too high, your SSDI can be suspended or terminated. Social Security has a trial work period that lets you test your ability to work without when ready losing benefits, but if you earn above a certain amount for nine months, your SSDI will eventually stop.

When your SSDI ends, you may then become may be able to access for SSI if your income and assets fall within SSI limits. This is one of the few situations where you can move from SSDI to SSI. For example, if you were receiving $1,200 SSDI and $0 SSI, and your SSDI ends because you are working, you might then may have access to for $700 SSI based on your new lower income. You would report the change to Social Security, and they would process your SSI claim.

This transition can take several weeks. During that time, you may have a gap in benefits. It is important to contact Social Security as soon as your work situation changes so they can begin the SSI process right away.

How your living situation affects which benefit you receive

Your living arrangement can make a difference in your SSI amount but not your SSDI amount. If you live in someone else's household and they provide you with food or shelter, your SSI payment is reduced by a set amount called an in-kind support and maintenance (ISM) reduction. This reduction does not explore to SSDI.

Because of this, if you are receiving both benefits and your living situation changes—for example, you move out of your parent's house into your own apartment—your SSI amount may increase. If your new SSI amount becomes larger than your SSDI, Social Security will switch you to SSI and stop your SSDI. This is rare but possible.

Similarly, if you move in with family members who support you, your SSI amount decreases. If it drops below your SSDI amount, you will continue receiving only SSDI. You must report any change in where you live within 10 days so Social Security can recalculate your benefits correctly.

What happens if you receive the wrong amount

If Social Security pays you both benefits in the same month by mistake, or pays you more than you should receive, that overpayment must be repaid. Social Security will send you a notice explaining the overpayment and how much you owe. You can request a waiver of the overpayment if you can show that you were not at fault and that repaying it would cause you hardship, but the process takes time.

To avoid overpayments, report changes when ready: if you start working, if your income changes, if you move, if your living situation changes, or if you receive any other income. You can report changes online through your my Social Security account, by phone at 1-800-772-1213, or in person at your local Social Security office.

Frequently Asked Questions

If I am approved for both SSI and SSDI, do I get both payments?

No. Social Security pays you whichever benefit is larger. If your SSDI is $900 and your SSI would be $600, you receive $900 SSDI only. You do not receive both amounts.

Can my SSDI increase enough that I lose my SSI?

Yes. If your SSDI increases—usually at your full retirement age or due to a cost-of-living adjustment—and becomes larger than your SSI amount, Social Security will stop your SSI payments. You will receive only SSDI from that point forward.

What if I go back to work and lose my SSDI?

If your SSDI ends because you are working, you may then become may be able to access for SSI if your income and assets are low enough. Contact Social Security to start an SSI claim. There may be a gap in benefits while your claim is processed.

Do I have to report changes if I am receiving both benefits?

Yes. You must report any change in income, work status, living situation, or other benefits within 10 days. Failing to report changes can result in overpayments that you will have to repay.

What is the difference between SSI and SSDI if I can only get one?

SSDI is based on your work history and is not affected by your income or living situation. SSI is based on financial need and is reduced if you have other income or assets. The program you receive depends on which benefit amount is larger.
