You cannot draw both SSDI and Social Security retirement benefits simultaneously, but you can switch from one to the other when you reach full retirement age.

Social Security Disability Insurance (SSDI) and Social Security retirement benefits are two separate payment streams from the same program. The Social Security Administration treats them as mutually exclusive — you receive one or the other, not both at the same time. However, the rules change once you reach your full retirement age, which creates a specific window where you can transition from disability to retirement benefits.

The reason for this structure is how Social Security calculates your benefit amount. Your SSDI payment is based on your earnings record and the age at which you became disabled. Your retirement benefit is based on your earnings record and the age at which you claim. These two calculations can produce different monthly amounts, and Social Security pays whichever one is higher once you reach full retirement age — but only one payment per month.

Key Takeaways

  • SSDI automatically converts to retirement benefits at your full retirement age; you do not need to reapply or notify Social Security, though you should confirm the transition occurred.
  • Your monthly payment may increase, decrease, or stay the same when you convert, depending on whether your retirement benefit calculation is higher than your SSDI amount.
  • If you continue working while on SSDI, your earnings may reduce or eliminate your benefit until you reach full retirement age, at which point work does not affect your payment.
  • Family members receiving benefits on your SSDI record will also convert to retirement benefits on your record at your full retirement age.
  • You cannot delay your conversion past full retirement age to increase your payment — the switch happens automatically, though you can request a voluntary suspension in limited circumstances.

How the Automatic Conversion Works at Full Retirement Age

When you turn your full retirement age — which ranges from 66 to 67 depending on your birth year — Social Security automatically converts your SSDI case to a retirement case. You do not file a new process or contact the agency. The conversion happens in the Social Security computer system, and your case worker updates your record.

In most cases, you will not notice the change. Your payment continues to arrive on the same schedule, often on the same day of the month. However, the legal basis for your payment shifts from disability to retirement, which matters for how work income is treated and which rules govern your benefits going forward.

You should receive a notice from Social Security explaining the conversion and your new benefit amount. If you do not receive one within a month of your full retirement age birthday, contact your local Social Security office or call 1-800-772-1213 to confirm the conversion occurred. This is especially important if your payment amount changed, because you need to verify the calculation is correct.

When Your Payment Amount Changes After Conversion

Your SSDI benefit and your retirement benefit are calculated using the same earnings record but different formulas. At full retirement age, Social Security compares the two amounts and pays you whichever is higher. For many people, the two amounts are similar or identical, so the conversion produces no change in the monthly check.

However, if you claimed SSDI at a younger age — say, age 35 — your benefit was calculated based on your earnings up to that point. If you continued working and earning after you became disabled, your retirement benefit calculation includes those additional years of earnings, which can increase your payment. Conversely, if you had very high earnings early in your career and lower earnings later, your retirement benefit might be lower than your SSDI amount.

You can request a benefit estimate from Social Security before your full retirement age to see what your retirement benefit will be. Visit ssa.gov, create a my Social Security account, and view your statement. The statement shows your projected retirement benefit at full retirement age, which you can compare to your current SSDI amount.

How Work Income Affects You Before and After Full Retirement Age

While you are on SSDI, Social Security applies the Substantial Gainful Activity (SGA) test to your work earnings. In 2024, if you earn more than $1,550 per month (or $2,590 if you are blind), Social Security may conclude you are no longer disabled and terminate your benefits. Even if your earnings are below SGA, they are tracked and reported to the agency.

Once you reach full retirement age and convert to retirement benefits, the SGA test no longer applies. You can earn any amount without affecting your payment. This is a major change: work no longer threatens your benefits, and you do not need to report earnings to Social Security.

If you are currently on SSDI and working, or planning to work, understand that your earnings between now and full retirement age are scrutinized. Social Security has a Trial Work Period that allows you to test your ability to work without when ready benefit loss, but after that period ends, high earnings can reduce or eliminate your check. A disability lawyer can help you understand how your specific work situation interacts with these rules.

What Happens to Family Members on Your SSDI Record

If you have a spouse, ex-spouse, or children receiving benefits on your SSDI record, they also convert to retirement benefits at your full retirement age. Their payments are recalculated based on your retirement benefit amount, and they receive whichever is higher — their SSDI amount or their retirement amount.

Family members do not have a separate full retirement age; they convert when you do. A child on your SSDI record may continue receiving benefits past your full retirement age if they are under 19 and in high school, or if they became disabled before age 22 (in which case they receive disabled adult child benefits indefinitely).

If you have an ex-spouse on your record, they also convert at your full retirement age, even if you have not remarried or had contact with them in years. Social Security manages this conversion automatically.

Delaying Your Conversion or Suspending Benefits

You cannot delay your conversion past full retirement age to increase your payment the way you can delay claiming retirement benefits. The conversion happens automatically, and your payment amount is set based on the rules in effect at that time.

However, you have a limited option called voluntary suspension. After you reach full retirement age, you can ask Social Security to suspend your benefits temporarily. While suspended, you do not receive a monthly check, but your benefit amount grows slightly each month until age 70 (a process called delayed retirement credits). When you resume benefits, your payment will be higher.

Voluntary suspension is rarely used after a conversion from SSDI because most people need the income. It is more common among people who claim retirement benefits at full retirement age and want to increase their payment by waiting until 70. If you are considering suspension, discuss it with a disability lawyer or a Social Security representative, because the rules are complex and the decision is permanent once you resume.

What to Do if Your Conversion Payment Seems Wrong

If your payment amount decreases significantly after conversion, or if you believe Social Security made an error in the calculation, you have the right to request a reconsideration. You must request reconsideration within 60 days of receiving the notice of conversion.

To request reconsideration, contact your local Social Security office in person, by phone at 1-800-772-1213, or by mail. Explain why you believe the calculation is incorrect and provide any documents that support your position — for example, a benefit estimate from your my Social Security account, or evidence of additional earnings that should have been included.

If Social Security denies your reconsideration request, you can file a formal appeal called a hearing request before an Administrative Law Judge. This process takes several months, but you have the right to present evidence and testimony. Many people hire a disability lawyer at this stage because the hearing process is formal and the stakes are your ongoing income.

Frequently Asked Questions

What is my full retirement age?

Full retirement age depends on your birth year. If you were born between 1943 and 1954, your full retirement age is 66. If you were born between 1955 and 1960, it ranges from 66 and 2 months to 66 and 10 months. If you were born in 1960 or later, your full retirement age is 67. You can find your exact full retirement age on your Social Security statement or by calling 1-800-772-1213.

Can I claim retirement benefits before my full retirement age instead of waiting for the automatic conversion?

No. Once you are on SSDI, you cannot switch to retirement benefits before full retirement age. Social Security will not process a retirement claim while you are receiving disability benefits. You must wait for the automatic conversion at full retirement age.

Will my Medicare coverage change when I convert from SSDI to retirement?

No. You remain on Medicare Part A and Part B under the same terms. Your coverage does not change, and your premiums are not affected by the conversion from SSDI to retirement. However, if you are working and have employer health insurance, you may want to review your Medicare enrollment to avoid penalties.

What if I disagree with my conversion and want to stay on SSDI?

You cannot stay on SSDI past your full retirement age. The conversion is automatic and mandatory. However, if you believe Social Security made an error in calculating your retirement benefit amount, you can request reconsideration within 60 days of the conversion notice.

Do I need to tell Social Security about my conversion?

No, the conversion is automatic. However, you should confirm it occurred by checking your my Social Security account or calling 1-800-772-1213. If you do not receive a conversion notice or your payment changes unexpectedly, contact Social Security to verify the transition was processed correctly.
