You can collect both, but the rules depend on which disability program you're in
If you receive Social Security Disability Insurance (SSDI), you are already collecting Social Security — it is the same payment. You cannot collect SSDI and regular retirement Social Security at the same time because SSDI converts to retirement benefits at your full retirement age, using the same account.
If you receive Supplemental Security Income (SSI), which is a separate needs-based program, you can also receive Social Security retirement or survivor benefits. The two payments stack, but SSI has strict income and resource limits that may reduce your SSI amount if your other income is high enough.
The key difference is that SSDI is an earned benefit tied to your work record, while SSI is a safety-net program for people with low income and few assets. Understanding which one you have, or whether you might have both, determines what you can actually receive.
Key Takeaways
- SSDI and retirement Social Security use the same benefit account, so you cannot collect both — SSDI automatically becomes retirement benefits at your full retirement age.
- SSI and Social Security retirement or survivor benefits can be collected together, but SSI payments shrink if your other income exceeds the monthly limit.
- Your work history determines whether you may have access to for SSDI; your income and assets determine SSI, regardless of work history.
- If you are collecting SSDI and reach full retirement age, the Social Security Administration converts your case automatically — your payment amount may change.
- Earning income while on either program can affect your payment; SSDI has a work incentive program that lets you test return-to-work without losing benefits when ready.
How SSDI and retirement Social Security relate to each other
SSDI is Social Security for people who cannot work due to disability. When you turn your full retirement age — between 66 and 67 depending on your birth year — the Social Security Administration stops calling it disability and starts calling it retirement. The payment continues from the same account. You do not explore for retirement; it happens automatically.
The amount you receive may change slightly at that conversion because the formula shifts, but you are not collecting two separate benefits. If you were hoping to delay retirement to earn a higher payment while living on disability income, that does not work — SSDI and delayed retirement benefits cannot both be yours.
Family members can collect on your SSDI record. A spouse or child may receive a payment based on your earnings history while you collect SSDI. Those payments continue even after you convert to retirement, and they follow the same family maximum rules.
When you can collect SSI alongside other Social Security payments
SSI is a federal payment for people age 65 or older, blind, or disabled, who have limited income and resources. Unlike SSDI, SSI does not require a work history. You can receive SSI and Social Security retirement benefits at the same time, or SSI and Social Security survivor benefits at the same time.
However, SSI has a monthly income limit. In 2024, the limit is $943 per month for an individual (amounts vary by state and change yearly). If you receive $500 in Social Security retirement and $600 in SSI, your total income is $1,100 — above the limit. The Social Security Administration will reduce your SSI payment by the overage, leaving you with roughly $343 in SSI plus your $500 retirement payment.
SSI also counts your assets. You can own no more than $2,000 in countable resources as an individual. A home you live in and one vehicle do not count, but savings, stocks, and second properties do. If you inherit money or receive a lump-sum payment, it can disqualify you from SSI until you spend it down.
What happens to your SSDI when you reach full retirement age
The Social Security Administration converts your case automatically. You do not need to do anything. Your SSDI case becomes a retirement case in the month you turn your full retirement age. The payment continues, though the amount may shift slightly because the benefit calculation changes.
If you have been working and earning above the substantial gainful activity limit (in 2024, that is $1,550 per month), your benefits may have been suspended during your working years. Once you reach full retirement age, the earnings limit no longer applies. You can work and earn as much as you want without losing any benefit.
If you have a spouse or children collecting on your SSDI record, their benefits also convert. A child's benefit ends when they turn 19 (or 22 if in high school full-time), regardless of whether you converted to retirement.
How work affects your disability or Social Security payment
SSDI has a work incentive program called Plan to Achieve Self-Support (PASS). You can work and earn money while on SSDI without losing your benefit when ready. The program lets you set aside income and resources to reach a work goal — such as completing a degree or starting a business — without that money counting against you.
If you work without using PASS, you have a trial work period of nine months (not necessarily consecutive) during which you can earn any amount and keep your full SSDI payment. After the trial work period ends, if your earnings stay above the substantial gainful activity limit for nine consecutive months, your benefits stop. If earnings drop below the limit, your benefits restart.
SSI has stricter work rules. The first $65 of monthly earnings and half of earnings above that do not count toward the income limit. So if you earn $200 per month, only $135 counts as income ($65 excluded, plus half of the remaining $135). This allows some work without losing SSI, but high earnings will reduce or eliminate your payment.
Social Security retirement has no earnings limit once you reach full retirement age. Before that age, you lose $1 in benefits for every $2 you earn above the annual limit (in 2024, $23,400 for the year you reach full retirement age).
Collecting survivor benefits and disability at the same time
If you are receiving Social Security survivor benefits because a parent or spouse died, and you also may have access to for SSDI based on your own disability, you cannot collect both. The Social Security Administration pays you whichever benefit is higher, not both.
If you are receiving survivor benefits and reach full retirement age, you convert to retirement benefits on your own record (if you have enough work history) or continue on the deceased person's record, whichever is higher. Again, you receive one payment, not two.
If you receive SSI and also may have access to for survivor benefits, you can collect both. The survivor benefit counts as income for SSI purposes, which will reduce your SSI payment the same way Social Security retirement does.
Documents and information you need to understand your situation
Request your Social Security Statement from ssa.gov or call 1-800-772-1213. The statement shows your earnings history, estimated retirement benefit, and current benefit status if you are already collecting. It tells you whether you are on SSDI, SSI, or retirement.
If you have multiple family members collecting on one record, ask the Social Security Administration for a benefit verification letter for each person. This document shows the exact amount each person receives and the basis for the payment (disability, retirement, survivor, or family member).
Keep records of any work you do while on SSDI or SSI. Report earnings to Social Security within the month you earn them. Failure to report can result in overpayment, which you will be asked to repay.
Frequently Asked Questions
Can I collect SSDI and then switch to retirement benefits later to get a higher payment?
No. SSDI automatically converts to retirement at your full retirement age using the same account and the same benefit amount (adjusted by the retirement formula). You cannot delay one and collect the other. The conversion is automatic and you have no choice in the timing.
If I am on SSI and start receiving Social Security retirement, will I lose my SSI?
Not automatically, but your SSI payment will shrink. SSI counts your retirement income against the monthly limit. If your retirement payment is less than the SSI limit ($943 in 2024), you keep some SSI. If your retirement payment exceeds the limit, SSI stops. The two payments together may be less than SSI alone was.
What is the trial work period and can I use it more than once?
The trial work period is nine months (not consecutive) during which you can earn any amount on SSDI without losing your benefit. You have one trial work period per SSDI case. After it ends, if you continue earning above the substantial gainful activity limit, benefits stop. If earnings drop below the limit later, benefits restart, but you do not get a second trial work period.
Do I have to tell Social Security if I inherit money while on SSI?
Yes. Inherited money counts as a resource for SSI. If the inheritance pushes your total resources above $2,000, you become ineligible for SSI until you spend it down. Report the inheritance to Social Security within 10 days to avoid overpayment.
Can my child collect on my SSDI record after I convert to retirement?
Yes, if they were already collecting. A child's benefit continues after you convert, but it ends when they turn 19 (or 22 if in high school full-time). A child cannot start a new benefit after you convert to retirement; they can only collect if they were already on your SSDI record.
