You cannot collect both SSI and SSDI simultaneously, but you may be able to switch from one to the other

Social Security Supplemental Security Income (SSI) and Social Security Disability Insurance (SSDI) are separate programs with different rules, funding sources, and payment amounts. The Social Security Administration does not allow you to receive both payments in the same month. However, your situation may change over time — you might start on one program and later move to the other, or you might receive one type of benefit while waiting for another decision.

The key difference is how you became disabled and what work history you have. SSDI is based on your own work record or your parent's work record if you became disabled before age 22. SSI is a needs-based program that looks at your income and assets, regardless of work history. Understanding which program you are on now, and whether you could switch later, depends on your specific circumstances.

Key Takeaways

  • SSI and SSDI are two separate programs; you receive a payment from one or the other, never both in the same month.
  • If you are on SSI and later gain enough work credits, you may become may have access to to SSDI instead, which typically pays more.
  • If you are on SSDI and your work credits expire, you may fall back to SSI if your income and assets meet the limit.
  • Some people receive SSI while waiting for an SSDI decision, and the programs coordinate so you do not receive duplicate payments.
  • Your state may also provide a state supplement to SSI, which is separate from the federal SSI amount.

How the Social Security Administration prevents duplicate payments

When you file for one program, the Social Security Administration checks whether you are already receiving the other. If you are approved for SSDI while on SSI, your SSI stops and you begin receiving SSDI instead. The agency does not pay both; it switches you over. The same happens in reverse — if your SSDI ends and you meet SSI's income and asset limits, you may be moved to SSI.

During the transition between programs, there may be a gap of one or two months while the paperwork processes. You should contact your local Social Security office if you notice a missing payment, because delays in switching can sometimes leave you without income temporarily. The office can tell you which program you are currently on and when the change will take effect.

When you might move from SSI to SSDI

If you are receiving SSI now, you may become may have access to to SSDI later if you work enough to earn Social Security work credits. Work credits are based on your earnings in covered employment — you earn credits by paying Social Security taxes through your job. Once you have enough credits (the number depends on your age), you become insured for SSDI.

This can happen even if you are currently unable to work. For example, if you worked before becoming disabled and paid into Social Security, you may eventually have enough credits to may have access to for SSDI even while on SSI. When this occurs, SSDI usually pays more than SSI because it is based on your earnings record rather than your current income level. The Social Security Administration will notify you if this change occurs.

When you might move from SSDI to SSI

SSDI is based on work credits that expire over time. If you became disabled at a young age and your parent or spouse was the worker whose record you used, those credits may eventually run out. When your SSDI ends, you may be able to move to SSI if your income and assets fall below the program's limits.

SSI has strict asset limits — as of 2024, you can own no more than $2,000 in countable resources if you are single, or $3,000 if you are married and both are on SSI. Your home and one vehicle are not counted. If you have savings or other assets above these amounts, you would not meet SSI's requirements even if your SSDI ended. Some people plan ahead by spending down assets or placing them in certain types of trusts to preserve SSI may be able to access.

SSI while waiting for an SSDI decision

If you have applied for SSDI but your case is still pending, you may be able to receive SSI in the meantime. This is called concurrent receipt. You must meet SSI's income and asset requirements, and your disability must be the same condition you claimed for SSDI. Once your SSDI is approved, your SSI stops and you receive only the SSDI payment going forward.

If your SSDI is denied, you keep your SSI as long as you continue to meet its requirements. This can be a safety net while you wait for a decision that may take several months or longer. You do not need to choose between programs — you can pursue SSDI while receiving SSI, and the Social Security Administration will coordinate the payments.

State supplements and how they fit in

Some states provide an additional payment on top of the federal SSI amount. This is called a state supplement, and it is paid by the state, not the federal government. If you receive SSI in a state that offers a supplement, you get both the federal SSI payment and the state payment in the same month. This is not the same as receiving two federal programs — it is one federal program plus a state add-on.

If you move from SSI to SSDI, you lose the federal SSI payment but you may keep the state supplement, depending on your state's rules. Some states continue the supplement for people on SSDI; others do not. You should contact your state's social services office to understand what you would receive if your program changes.

What happens to your benefits if you return to work

Both SSI and SSDI have work incentives that allow you to earn some income without losing all your benefits. These are not the same as collecting both programs — you are still on one program or the other. However, the work rules differ between them, and understanding which program you are on matters for how much you can earn.

SSDI allows you to earn up to a certain amount per month (called substantial gainful activity, or SGA) without losing your benefits. SSI has a different earnings limit and counts your income differently. If you are working or thinking about returning to work, you should contact your local Social Security office to understand how your earnings will affect your specific program.

Frequently Asked Questions

If I am on SSI now, will I automatically move to SSDI if I become may have access to?

The Social Security Administration will notify you if you become may have access to to SSDI based on work credits or a change in your case. You do not need to reapply; the agency handles the switch. However, you should report any work you do to Social Security, because that is how you earn the credits that lead to SSDI entitlement.

Can I appeal an SSI or SSDI decision while receiving the other program?

Yes. If you are on SSI and your SSDI was denied, you can appeal the SSDI decision while continuing to receive SSI. The two programs are separate, so an appeal on one does not affect the other. You should file your appeal within 60 days of the denial notice.

What if I receive SSDI based on my parent's work record and they pass away?

Your SSDI continues as long as you remain disabled. You do not lose benefits when your parent dies. However, if you were also receiving a state supplement tied to your parent's income, that may end. Contact Social Security to understand how your specific benefits are affected.

Do I have to report my SSI to SSDI, or vice versa?

You do not need to report one program to the other — Social Security's internal systems already know about both. However, you must report changes in your income, living situation, or work status to whichever program you are currently on, because both programs use this information to calculate your payment.
