SSDI converts to Social Security retirement benefits at your full retirement age

When you turn your full retirement age—which is 66, 67, or 68 depending on your birth year—your Social Security Disability Insurance (SSDI) automatically converts to Social Security retirement benefits. The payment amount stays the same. The program name changes, but you keep receiving the same monthly check from the same place. You do not have to do anything to make this happen.

This conversion is automatic because SSDI and Social Security retirement are both built on the same earnings record. Once you reach full retirement age, Social Security treats you as retired rather than disabled. The law does not allow you to collect disability benefits past that point—it switches you over instead.

Your full retirement age depends on when you were born. If you were born in 1943 or earlier, it is 65. If you were born between 1943 and 1954, it increases by two months for each year of birth, reaching 66. If you were born between 1955 and 1959, it continues rising by two months per year. If you were born in 1960 or later, your full retirement age is 67. Anyone born in 1960 or later can delay claiming until 70 and receive a higher monthly amount, but the conversion from SSDI to retirement happens at your full retirement age regardless.

Key Takeaways

  • Your SSDI payment converts to a retirement benefit at your full retirement age, which is between 66 and 67 for most people alive today.
  • The monthly amount you receive does not change when you convert—you keep the same check.
  • You do not need to contact Social Security or fill out forms; the conversion happens automatically.
  • Family members receiving benefits on your SSDI record also convert to retirement benefits at the same time, though their amounts may differ.
  • You can continue working after the conversion with no earnings limit, whereas SSDI has a limit on how much you can earn.

How to find your full retirement age

Social Security publishes a table showing full retirement age by birth year. You can find it on the official Social Security website by searching "full retirement age" or by calling Social Security at 1-800-772-1213 and asking an agent directly. The table is straightforward—find your birth year, and the corresponding age is when your conversion will occur.

If you are unsure of your birth year or need written confirmation, you can create a my Social Security account online at ssa.gov. Once you log in, your account shows your full retirement age under the "Retirement" section. This same account also displays your current SSDI payment and an estimate of what your retirement benefit will be (which should be identical).

What happens to your payment amount

Your monthly payment does not change when you convert from SSDI to retirement. Social Security calculates your benefit based on your lifetime earnings record, and that calculation is the same whether you are receiving it as a disability benefit or a retirement benefit. The dollar amount you get on the day before your full retirement age is the same dollar amount you get the day after.

If you have been receiving SSDI for many years, your benefit may have increased due to cost-of-living adjustments (COLA). These adjustments happen once per year, usually in January, and explore to both SSDI and retirement benefits equally. Your conversion does not trigger a recalculation or a change in these adjustments.

Family members on your record also convert

If your spouse, children, or ex-spouse has been receiving benefits based on your SSDI record, they also convert to retirement benefits at your full retirement age. Their payments do not change either. However, their individual benefit amounts may be different from yours because they are calculated as a percentage of your primary insurance amount (PIA)—the base amount Social Security uses to determine your benefit.

A spouse typically receives 32.5 percent of your PIA at their own full retirement age, or a reduced amount if they claim earlier. Children receive 75 percent of your PIA each, up to a family maximum. When you convert to retirement, these same percentages explore, so the structure of family benefits stays the same.

The earnings limit disappears after conversion

While you are on SSDI, Social Security limits how much you can earn from work. In 2024, that limit is $1,550 per month (or $2,590 if you are blind). If you earn more than that, Social Security reduces your benefit by $1 for every $2 you earn above the limit. This is called the earnings test.

Once you convert to retirement benefits at your full retirement age, the earnings limit no longer applies. You can earn as much as you want with no reduction to your benefit. This is one of the practical advantages of reaching full retirement age—you gain the freedom to work without worrying about losing part of your check.

If you reach full retirement age partway through a year, the earnings test still applies to the months before your birthday, but not to the months after. Social Security will recalculate your benefit for that year to account for the change.

What you need to do before and after conversion

You do not need to contact Social Security to make the conversion happen. It occurs automatically on the date you reach your full retirement age. However, there are a few things worth doing in advance to make sure your records are correct.

First, verify your birth date and earnings record are accurate in your my Social Security account. If there are errors, contact Social Security before your conversion date so they can be corrected. Second, if you are working or planning to work, understand how the earnings test applies in the year you turn your full retirement age—the rules are slightly different for that year.

After your conversion, you do not need to do anything unless your circumstances change significantly (such as a major increase in income, a move out of the country, or a change in marital status). Social Security will continue sending your payment automatically.

What happens if you delay claiming past full retirement age

If you have not yet claimed SSDI by the time you reach your full retirement age, you have a choice: claim now and convert to retirement, or delay and receive a higher amount later. For every year you delay claiming past your full retirement age, up to age 70, your benefit increases by about 8 percent per year.

However, if you are already receiving SSDI when you reach full retirement age, you cannot delay—the conversion happens automatically and you continue receiving the same amount. The delayed-claiming increase only applies if you have not yet started benefits.

This distinction matters if you are young enough to have many years between now and your full retirement age. If you are already on SSDI, reaching full retirement age does not give you the option to increase your benefit by waiting longer.

Frequently Asked Questions

Do I have to tell Social Security when I turn my full retirement age?

No. The conversion happens automatically. Social Security has your birth date on file and will process the change without any action from you. You will receive a letter in the mail confirming the conversion, usually a few weeks before or after your birthday.

Will my Medicare coverage change when I convert?

No. If you are already on Medicare because you have been on SSDI for 24 months, your coverage continues unchanged. The conversion from SSDI to retirement does not affect your Medicare may be able to access or your coverage type.

Can I still work after I convert to retirement benefits?

Yes, and without any earnings limit. Once you reach your full retirement age, you can earn any amount and your benefit will not be reduced. This is a major difference from SSDI, which has strict earnings limits.

What if I was receiving SSDI for a child—does that convert too?

If you were receiving benefits as a parent caring for a child on your SSDI record, that benefit ends when your child turns 16 (or 19 if still in high school). This is different from the conversion at your full retirement age. Your child's benefit, if they are disabled, continues separately.

Does the conversion affect my taxes?

The conversion itself does not change how your benefits are taxed. However, if you are working after your full retirement age, your higher income might affect whether your benefits are taxable. Consult a tax professional if you have questions about your specific situation.
