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 Supplemental Security Income (SSI) and Social Security Disability Insurance (SSDI) are two separate programs with different rules. The Social Security Administration does not allow you to collect monthly payments from both programs simultaneously. However, your situation may change over time — you might start on one program and later move to the other, or you might receive benefits from one program while also getting other types of Social Security payments.

The key difference is how each program works. SSDI is based on your own work history or, in some cases, a parent's or spouse's work history. SSI is a needs-based program that looks at your income and resources, regardless of work history. Because they operate under different rules, the Social Security Administration treats them as mutually exclusive for monthly payments.

Key Takeaways

  • You cannot receive both SSI and SSDI monthly payments at the same time — Social Security will pay you from only one program.
  • If you receive SSDI and your payment falls below the SSI federal benefit rate, you may receive a small SSI top-up payment to bring you to the minimum.
  • You can switch from one program to the other if your circumstances change, such as when you reach full retirement age or if your work record becomes strong enough to may have access to for SSDI.
  • If you receive SSDI based on a parent's or spouse's record, you may also receive your own SSDI or SSI based on your own disability, but not both monthly payments.

When you might receive both programs in sequence

Many people start their benefits on SSI because they have little or no work history. As you work and build a record of Social Security contributions, you may eventually become insured for SSDI. When that happens, Social Security can switch you from SSI to SSDI, and your SSDI payment becomes your primary benefit.

The reverse can also occur. If you are receiving SSDI but your earnings record does not support a payment high enough to meet your needs, Social Security may supplement your SSDI with a small SSI top-up. This is not a separate payment — it is an additional amount added to your SSDI check to bring your total to the SSI federal benefit rate. The federal rate changes each year; in 2024 it was $943 per month for an individual, though your state may add more.

Another common transition happens at full retirement age. If you have been receiving SSDI, your benefits automatically convert to retirement benefits at that age. If your retirement payment is lower than your SSDI payment was, you will continue to receive the same amount through a process called Government Pension Offset protection.

The SSI top-up payment explained

A top-up is a small additional payment that brings your total monthly income to the federal SSI minimum. It is not a separate process or a second program — it is straightforward how Social Security handles situations where your SSDI payment is too low.

To receive a top-up, you must meet SSI's income and resource limits. Your SSDI payment counts as income, so if your SSDI is high enough, you will not may have access to for a top-up. Most people receiving a top-up have SSDI payments between $600 and $900 per month. If your SSDI payment is above the federal benefit rate, you will not receive a top-up, even if you have very few resources.

Top-ups are less common than they used to be because SSDI payments have risen over time. However, they still occur for people who worked very little before becoming disabled or who had low earnings during their working years.

How your work history affects which program you can receive

SSDI requires that you or your parent or spouse have paid enough Social Security taxes over a long enough period. The exact requirement depends on your age when you became disabled, but generally you need at least 20 quarters of coverage in the 10 years before you became disabled. A quarter of coverage is earned by paying Social Security taxes on about $1,550 of income in a three-month period; the exact amount changes each year.

SSI has no work history requirement. You can receive SSI if you are disabled, blind, or age 65 or older, and you have limited income and resources. Because of this, SSI is often the first program people turn to when they become disabled and have not worked much.

If you do not have enough work history for SSDI, you can still receive SSI. If you later work enough to build an SSDI record, you can switch programs. Social Security will notify you when you become insured for SSDI and will explain your options.

Receiving benefits on someone else's record plus your own

You can receive a payment based on a parent's or spouse's Social Security record and also receive your own SSDI or SSI — but you cannot receive two monthly payments from Social Security at the same time. Social Security will pay you the higher of the two amounts, not both.

For example, if you are receiving a disabled adult child benefit on your parent's record and you also become insured for SSDI based on your own work history, Social Security will pay you whichever amount is higher. You do not receive both payments added together.

This rule applies even if the payments come from different programs. If you are receiving SSI and you become insured for SSDI, your SSDI payment replaces your SSI payment. Social Security handles the transition automatically, though you should report any changes in your circumstances to make sure the switch happens correctly.

What happens to your SSI when you start SSDI

When you become insured for SSDI, Social Security will contact you to explain your options. In most cases, your SSI payments will stop and your SSDI payments will begin. The timing depends on when Social Security processes your case, but there is usually a one-month gap where you receive neither payment.

During this gap, you may still be covered by Medicaid if you were receiving it as an SSI recipient. Many states have a Medicaid continuation rule that keeps your coverage for a few months even after your SSI ends. You should contact your state Medicaid office to confirm your coverage during the transition.

If your SSDI payment is lower than your SSI payment was, you may receive a top-up to make up the difference. This is not may provide — it depends on whether your SSDI payment falls below the federal SSI benefit rate and whether you still meet SSI's income and resource limits.

How to report changes that might affect your benefits

If your work history changes, your income changes, or your living situation changes, you should report it to Social Security. These changes can affect which program you receive from and how much you receive.

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. Keep records of any changes — such as a new job, a move, or a change in who lives with you — because Social Security may ask for proof.

If you are unsure whether a change affects your benefits, report it anyway. It is better to report something that does not matter than to miss reporting something that does. Social Security can correct overpayments, but it is easier to avoid them by staying in touch.

Frequently Asked Questions

If I am on SSI and start working, will I lose my benefits?

Not when ready. SSI has work incentives that allow you to keep some benefits while you work. Your payment will be reduced based on your earnings, but you may still receive a partial payment. You should report your work to Social Security right away so they can calculate your new payment correctly.

Can I receive SSDI and retirement benefits at the same time?

No. When you reach full retirement age, your SSDI automatically converts to retirement benefits. You receive one payment, not both. The amount usually stays the same or increases slightly because of how Social Security calculates retirement benefits.

What if my SSDI payment is very low — can I get SSI to make up the difference?

Yes, through a top-up payment. If your SSDI is below the federal SSI benefit rate and you meet SSI's income and resource limits, Social Security will add a small amount to your SSDI check. You do not need to explore separately — Social Security handles this automatically.

If I am denied for SSDI, can I receive SSI instead?

Possibly. SSDI and SSI have different rules about what counts as a disability and what your income and resources can be. Being denied for one program does not mean you will be denied for the other. You can request to be considered for SSI if your SSDI claim is denied.

Will switching from SSI to SSDI affect my Medicaid or Medicare?

It may. SSI recipients receive Medicaid in most states. SSDI recipients become may be able to access for Medicare after 24 months of receiving benefits. Your coverage may change during the switch, so contact your state Medicaid office and Social Security to understand what will happen in your case.
