What counts as income that reduces your SSDI check

SSDI itself does not reduce your payment based on how much money you have in the bank. But earned income—money you make from working—does reduce your SSDI check, and the reduction follows a specific formula that changes each year.

The key number is called the substantial gainful activity (SGA) threshold. In 2024, if you earn more than $1,550 per month from work, Social Security counts you as working at a substantial level and will reduce or stop your benefits. This dollar amount changes annually, so you need to check the current year's threshold on the Social Security website or ask your local Social Security office.

Other types of income—such as interest from savings, rental income, or money from investments—do not reduce your SSDI payment. Only earnings from work matter for this calculation.

Key Takeaways

  • Earned income above the SGA threshold (currently $1,550 per month in 2024) reduces your SSDI payment dollar-for-dollar after a small buffer.
  • The first $65 of monthly earnings plus one-half of earnings above that amount are not counted against your benefits.
  • Unearned income such as savings interest, rental payments, or investment returns does not affect your SSDI check.
  • The SGA threshold changes each year, so you must verify the current amount before taking on work.
  • Work incentive programs like Impairment Related Work Expenses (IRWE) and Plans to Achieve Self-Support (PASS) can help you keep more of your earnings.

How the earnings deduction actually works

Social Security does not take your entire SSDI payment away the moment you earn over the SGA threshold. Instead, it uses a formula that lets you keep some earnings without losing benefits.

Here is how it works: the first $65 of your monthly earnings are not counted. Then, for every dollar you earn above $65, Social Security deducts 50 cents from your SSDI check. So if you earn $200 per month, Social Security counts only $135 of that ($200 minus the $65 buffer). Half of $135 is $67.50, which means your SSDI payment would be reduced by $67.50 that month.

This formula applies as long as your earnings stay below the SGA threshold. Once you cross that threshold, the rules change and your benefits may be suspended or stopped entirely, depending on how much you earn and for how long.

Work incentive programs that protect your earnings

Social Security offers programs designed to let you work and keep more of your SSDI without losing it. These are not automatic—you have to request them and provide documentation—but they can make a real difference if you are working or planning to work.

Impairment Related Work Expenses (IRWE) lets you deduct costs directly tied to your disability that you need in order to work. Examples include special transportation to get to your job, medications or medical equipment you use at work, or the cost of a job coach. These deductions come off your earnings before Social Security calculates the 50-cent reduction, which means you keep more of your check.

Plans to Achieve Self-Support (PASS) is a more complex tool that lets you set aside income and resources for a specific work goal—like training for a new job, buying equipment, or starting a business. Money in a PASS plan does not count against your SSDI, which means you can earn and save more without losing benefits. A PASS requires a written plan that you submit to Social Security, and it takes time to set up, but it can protect significant earnings.

A third option, Expedited Reinstatement, applies if you have already lost SSDI because of work earnings. It lets you return to benefits quickly if your earnings drop below the SGA threshold again, without having to reapply from scratch.

What happens if you earn above the SGA threshold

Crossing the SGA threshold does not mean you lose all your benefits when ready. Social Security uses a trial work period that lets you test your ability to work without losing SSDI.

During your trial work period, you can earn any amount and keep your full SSDI check for up to nine months (not necessarily consecutive). After the trial work period ends, if your earnings stay above the SGA threshold, Social Security will suspend your benefits. You do not lose SSDI permanently—it goes on hold—but you stop receiving payments.

If your earnings drop back below the SGA threshold later, you can restart your benefits without reapplying, as long as you do so within five years of when they were suspended. After five years, you would need to reapply.

Unearned income and other money that does not affect SSDI

Many types of money do not reduce your SSDI payment at all. Interest from a savings account, dividends from stocks, rental income from property you own, money from a trust, gifts from family members, and tax refunds all fall into this category. Social Security calls this unearned income, and it does not trigger the earnings deduction formula.

However, unearned income can affect other benefits you might receive. For example, if you also receive Supplemental Security Income (SSI), unearned income does reduce that payment. But SSDI itself is not affected by how much money you have or what non-work income you receive.

This distinction matters because some people receive both SSDI and SSI at the same time. If that is your situation, you need to track both programs separately, because the rules are different for each one.

Reporting your work and earnings to Social Security

You are required to report any work and earnings to Social Security, even if you think the amount is small. The best way to do this is through your my Social Security account, which you can access online at ssa.gov. You can report earnings monthly, and Social Security will use that information to calculate your payment correctly.

If you do not have an online account, you can call Social Security at 1-800-772-1213 or visit your local Social Security office in person. Keep records of your pay stubs and any work-related expenses you claim under IRWE or PASS, because Social Security may ask to see them.

Failing to report earnings can result in an overpayment—money Social Security paid you that you were not supposed to receive. You would then have to repay that money, which can happen through reduced future payments or a lump-sum payment, depending on what Social Security decides.

Frequently Asked Questions

Can I work part-time and keep my full SSDI check?

Yes, as long as your monthly earnings stay below $65 or you use the 50-cent deduction formula and your total earnings remain below the SGA threshold. If you earn $65 or less per month, your SSDI does not change. If you earn more, the formula applies: half of earnings above $65 reduces your check.

Does my spouse's income affect my SSDI?

No. SSDI is based on your own work record and your own earnings. Your spouse's income, savings, or other money does not reduce your SSDI payment. This is different from SSI, where a spouse's income can affect your benefits.

What if I get a one-time bonus or lump-sum payment from work?

A bonus or lump sum counts as earned income for the month you receive it. If the amount pushes your total earnings above the SGA threshold that month, your benefits may be affected. Report it to Social Security in the month you receive it so they can calculate your payment correctly.

Can I use a work incentive program if I am already working?

Yes. IRWE and PASS can be set up at any time, even if you are already employed. You do not have to wait until you start a new job. Contact your local Social Security office or ask to speak with a work incentive planning specialist, who can help you figure out which program fits your situation.

What is the difference between SSDI and SSI for work earnings?

SSDI uses the SGA threshold and the 50-cent deduction formula. SSI has stricter rules: it counts unearned income and has lower earnings limits. If you receive both programs, you must track earnings separately for each one, because the rules are different.
