Retirement income does reduce your SSDI payment, but only if you're receiving both at the same time

If you're already collecting Social Security retirement benefits and you're approved for SSDI, the two programs don't work independently. Social Security has a rule called the Government Pension Offset and a separate calculation called deemed earnings that can lower your SSDI payment. The exact reduction depends on when you were born, when you started collecting retirement, and how much you earn from work.

The most important thing to understand: you don't lose SSDI may be able to access because you have retirement income. You keep the SSDI approval. But your monthly payment from SSDI may be smaller than it would be if you had no other income.

This is different from Supplemental Security Income (SSI), which has strict asset and income limits that can disqualify you entirely. SSDI has no asset limit and no income limit that bars you from the program—but income does affect the payment amount.

Key Takeaways

  • Retirement benefits and SSDI can both be paid to you, but receiving retirement income reduces what you get from SSDI through a calculation called deemed earnings.
  • If you were born before 1954 and started retirement before age 62, the Government Pension Offset may also reduce your SSDI payment.
  • Work income above a certain threshold (called substantial gainful activity) can also lower your SSDI payment or pause it temporarily.
  • The reduction is not permanent—if your retirement income stops or decreases, your SSDI payment can increase again.
  • You should report any change in retirement income to Social Security within 10 days so your payment is calculated correctly.

How deemed earnings reduce your SSDI payment

When you receive both retirement and SSDI, Social Security uses a process called deeming to count some of your retirement income as if it were work earnings. This affects how much SSDI you receive.

Here's how it works: Social Security subtracts an amount called the exclusion from your retirement income. In 2024, the exclusion is $23 per month. Any amount above that is counted as deemed earnings. For every dollar of deemed earnings above a second threshold (called the offset amount, which varies by year), your SSDI payment is reduced by $1.

The offset amount in 2024 is $943 per month. This means if your retirement income is $1,000 per month, Social Security would subtract $23 (the exclusion), leaving $977 in deemed earnings. Since $977 is above the $943 offset, you would lose $34 from your SSDI payment ($977 minus $943).

These dollar amounts change each year. Social Security publishes the current exclusion and offset amounts on its website, and you can also ask your local Social Security office for the figures that explore to your case.

The Government Pension Offset and when it applies

If you were born before January 2, 1954, and you receive a government pension (such as from federal, state, or local employment), the Government Pension Offset may reduce your SSDI payment by up to two-thirds of that pension amount.

This rule applies only if you started receiving your government pension before you turned 62. If you started your pension at 62 or later, the offset does not explore to SSDI—though it does explore to other Social Security benefits like spousal or survivor benefits.

The Government Pension Offset is separate from the deemed earnings calculation. Both can explore to your case at the same time, which means your SSDI payment could be reduced by both mechanisms. This is one reason it's important to tell Social Security about all sources of income and pensions when you explore for SSDI.

Work income and substantial gainful activity

SSDI also has rules about work income. If you earn more than a certain amount per month from work, Social Security considers you to be engaging in substantial gainful activity, which means you're working at a level that suggests you're not disabled.

In 2024, the threshold for substantial gainful activity is $1,550 per month (or $2,590 if you are blind). If you earn more than this amount, your SSDI can be suspended or terminated, depending on how long you've been receiving it and other factors.

Work income is different from retirement income. Social Security allows you to test your ability to work through a period called the trial work period, during which you can earn any amount and still receive your full SSDI payment. After the trial work period ends, the substantial gainful activity rule applies.

Retirement income does not count toward substantial gainful activity—only earnings from work do. So you could have high retirement income and still meet the work-related requirements for SSDI.

What happens if your retirement income changes

If your retirement income increases, your SSDI payment will decrease (or stop, if the reduction is large enough). If your retirement income decreases or stops, your SSDI payment will increase to make up the difference.

Social Security recalculates your payment each month based on the income you report. This means your SSDI amount can go up and down from month to month if your retirement income varies. Some people receive a smaller SSDI check in months when they have higher retirement income, and a larger check in months when retirement income is lower.

You must report changes in your income to Social Security within 10 days. You can report changes online through your my Social Security account, by phone, or in person at your local Social Security office. Failing to report changes can result in an overpayment, which Social Security may ask you to repay.

How to find out what your SSDI payment will be

The only way to know your exact SSDI payment amount is to contact Social Security directly. You can call 1-800-772-1213 (TTY 1-800-325-0778) or visit your local Social Security office with information about your retirement income, any government pensions, and any work income.

When you call or visit, have ready: your Social Security number, the amount of your monthly retirement benefit, the date you started receiving retirement, and information about any other income or pensions. A Social Security representative can calculate what your SSDI payment would be under your specific circumstances.

You can also create a my Social Security account online at ssa.gov. Once you're approved for SSDI, you can log in to see your payment amount and report changes in income.

Frequently Asked Questions

Can I get SSDI if I'm already getting retirement benefits?

Yes. You can receive both SSDI and retirement benefits at the same time. Your SSDI payment will be reduced based on your retirement income, but you won't be denied SSDI straightforward because you're receiving retirement. The two programs can run together, though your total payment from both may be less than if you had only one.

Will my SSDI stop if my retirement income is too high?

Your SSDI won't stop because your retirement income is high. However, if your retirement income is very large, your SSDI payment could be reduced to zero. This is different from SSI, which has income limits that can disqualify you entirely. With SSDI, the program itself doesn't end—your payment just becomes very small or stops temporarily.

What if I have both a government pension and retirement income?

Both can reduce your SSDI payment. The Government Pension Offset applies to your government pension (if you were born before 1954 and started the pension before age 62), and deemed earnings explore to your retirement income. Social Security will calculate both reductions and explore them to your SSDI payment. The total reduction could be substantial, so it's worth asking Social Security to calculate your exact payment before you make decisions about when to start retirement or pension benefits.

Do I have to report my retirement income to Social Security?

Yes. You must report any change in your retirement income within 10 days. Social Security uses this information to calculate your SSDI payment correctly. If you don't report changes, you may be overpaid, and Social Security will ask you to return the extra money.

Can my SSDI payment go back up if my retirement income decreases?

Yes. Your SSDI payment is recalculated each month based on the income you report. If your retirement income decreases, your SSDI payment will increase. If your retirement income increases, your SSDI payment will decrease. This means your check amount can change from month to month depending on your income that month.
