You cannot collect both full Social Security retirement benefits and SSDI simultaneously — but the rules about what you can collect are more specific than a straightforward no.

If you have already started collecting Social Security retirement benefits, you cannot also receive SSDI (Social Security Disability Insurance). The Social Security Administration treats these as two different benefit programs, and you receive whichever one pays the higher amount. If you become disabled after you have started collecting retirement benefits, you do not automatically switch to SSDI — you keep your retirement benefit at the same rate.

The situation reverses if you become disabled before you reach retirement age. If you are receiving SSDI and you reach your full retirement age, your SSDI automatically converts to a retirement benefit at the same payment rate. You do not collect both; the program straightforward changes its name on your account.

There is one narrow exception: if you have a child or a spouse who is disabled, they may be able to collect benefits on your SSDI record while you collect your own SSDI. That is a different benefit stream — it is not you collecting twice.

Key Takeaways

  • You receive either retirement benefits or SSDI, never both, and Social Security pays whichever amount is higher if you somehow may have access to for both.
  • If you become disabled after you start collecting retirement benefits, you keep your retirement benefit and do not switch to SSDI.
  • If you are on SSDI and reach your full retirement age, your benefit automatically converts to a retirement benefit with no change in payment amount.
  • A spouse or child may be able to collect benefits on your SSDI record at the same time you collect your own SSDI.
  • Your full retirement age depends on your birth year and ranges from 66 to 67 for people born between 1943 and 1960.

What happens when you reach full retirement age while on SSDI

When you turn your full retirement age — the age at which Social Security considers you may be able to access for an unreduced retirement benefit — your SSDI automatically converts to a retirement benefit. The payment amount stays exactly the same. The only thing that changes is the label on your account and the reason Social Security is paying you.

You do not have to do anything to make this conversion happen. Social Security tracks your birth date and makes the switch automatically in the month you reach full retirement age. You will receive a notice in the mail explaining the change, but your bank deposits continue without interruption.

This matters because it affects how much your family members can collect on your record. Once you convert to retirement benefits, a disabled adult child can no longer collect on your record — only a spouse or unmarried child under 19 (or 19 if still in high school) can collect family benefits. On an SSDI record, a disabled adult child has no age limit.

If you become disabled after you start collecting retirement

If you have already started collecting Social Security retirement benefits and then become disabled, you do not switch to SSDI. You continue collecting your retirement benefit at the same rate for the rest of your life. Social Security does not retroactively move you to a disability benefit, even if your disability would have may have access to you for a higher SSDI payment.

This is one reason the timing of when you start collecting matters. If you start retirement benefits at 62 and become disabled at 65, you are locked into the reduced retirement rate you claimed at 62. You cannot go back and claim SSDI instead, even though SSDI might have paid more.

The only exception is if you have not yet reached your full retirement age and you become disabled. In that case, you can contact Social Security and ask them to evaluate you for SSDI. If you are found disabled, Social Security will pay you SSDI instead of your reduced retirement benefit — but only going forward, not retroactively.

When a spouse or child can collect on your SSDI record

While you are collecting SSDI, certain family members can also collect benefits on your record at the same time. This is called a "family benefit" and it does not reduce your payment. Your spouse, ex-spouse (if married at least 10 years), or unmarried children can collect based on your SSDI record.

A spouse can collect at any age if they are caring for a child under 16 on your record, or at age 62 or older. An unmarried child can collect until age 19 if in high school, or indefinitely if disabled before age 22. A disabled adult child has no upper age limit as long as they remain disabled and you are collecting SSDI.

Once you convert to retirement benefits at your full retirement age, the rules tighten. A disabled adult child can no longer collect on your record. Only a spouse age 62 or older, or a spouse of any age caring for a child under 16, can continue to collect family benefits.

How the payment calculation works when you might may have access to for both

In rare cases, a person might technically may have access to for both a retirement benefit and an SSDI benefit based on different work records — for example, if they worked long enough to earn both their own SSDI record and a spousal retirement benefit. Social Security will not pay both. Instead, they calculate what you would receive under each program and pay you the higher amount.

This is called the "deemed filing" rule, though the rules around deemed filing have changed in recent years depending on your birth date. The key point is that you never receive two separate checks or two separate benefit amounts. Social Security determines which program gives you the most money and pays that amount.

If you are unsure whether you might may have access to under more than one program, you can contact Social Security directly and ask them to run the numbers. They can tell you what you would receive under each scenario and which one Social Security would actually pay.

Working while on SSDI and retirement benefits

The rules about working are different depending on which benefit you are collecting. If you are on SSDI, you can work and earn up to a certain amount per month without losing benefits. That amount changes each year; in 2024 it is $1,550 per month. If you earn more than that, your SSDI payment is reduced.

If you are collecting retirement benefits, there is no earnings limit once you reach your full retirement age. Before your full retirement age, there is an earnings limit, but it is higher than the SSDI limit. The exact amount depends on the year and whether you reach full retirement age during that year.

This is another reason the conversion from SSDI to retirement at full retirement age matters: once you convert, you can earn as much as you want without any reduction to your benefit.

How to find out which benefit you would receive

To understand what you might receive under each program, you need to contact Social Security directly. You can call them at 1-800-772-1213 (TTY 1-800-325-0778), visit a local Social Security office, or create an account on ssa.gov to view your earnings record and benefit estimates.

When you contact them, tell them you want to understand your options if you become disabled, or if you are already disabled and want to know what happens at your full retirement age. They can run scenarios and show you what you would receive under different circumstances.

You can also request a Social Security Statement from your online account, which shows your estimated retirement benefit at different ages and your estimated SSDI benefit if you became disabled today. This gives you a concrete number to work with rather than guessing.

Frequently Asked Questions

If I am on SSDI and I reach full retirement age, does my payment go up?

No. Your payment stays exactly the same when you convert from SSDI to retirement benefits at your full retirement age. The benefit amount does not change — only the program name changes on your account. Social Security ensures that the conversion does not leave you worse off.

Can I delay starting SSDI to get a higher payment later?

No. SSDI does not have a delayed retirement credit the way retirement benefits do. If you are found disabled, your benefit is set based on your earnings record at the time you start collecting. Waiting longer does not increase the amount you receive.

What if I was denied SSDI but I think I should have been approved?

You can file an appeal within 60 days of the denial notice. The appeals process has multiple levels: reconsideration, a hearing before an administrative law judge, and further appeals if needed. Many people are approved on appeal, especially with help from a disability advocate or attorney.

If my child is disabled, can they collect on my SSDI record after I convert to retirement?

Only if they became disabled before age 22. A disabled adult child can collect on your SSDI record indefinitely, but once you convert to retirement benefits, they can no longer collect. Plan ahead if you have a disabled adult child who depends on your record.

Does collecting SSDI affect my Medicare?

Yes. After you have been on SSDI for 24 months, you become may be able to access for Medicare Part A (hospital insurance) automatically, even if you are under 65. You will be enrolled in Part B (medical insurance) as well unless you specifically decline it. There is no separate process — it happens automatically.
