The earnings limit that matters: the substantial gainful activity threshold

Social Security sets a monthly earnings limit called substantial gainful activity, or SGA. In 2024, that limit is $1,550 per month for most people receiving SSDI. If you earn more than that in a month, Social Security may decide you are no longer disabled and can stop your benefits.

The limit changes each year—Social Security raises it in January based on wage growth. The exact amount for your year appears on your Social Security statement and on the official Social Security website. If you are blind, the SGA limit is higher: $2,590 per month in 2024.

This is not a hard cliff where you lose everything the moment you cross it. Social Security looks at your work history and your stated ability to work. But the SGA threshold is the number that triggers their review of whether you still meet the disability definition.

Key Takeaways

  • You can earn up to the SGA limit ($1,550 in 2024 for most people, $2,590 if blind) without automatically losing SSDI, but earnings above that trigger a review of your disability status.
  • Work incentives like the Trial Work Period let you test your ability to work for nine months without losing benefits, even if you earn above SGA.
  • The Plan to Achieve Self-Support (PASS) lets you set aside income and resources for a specific work goal without affecting your benefit amount.
  • You must report your earnings to Social Security within the month you earn them, or you risk overpayment and having to repay benefits.
  • The SGA limit changes every January, so you need to check the current year's amount before you start working.

The Trial Work Period: nine months to test your work ability

Social Security gives you a Trial Work Period of nine months during which you can earn any amount without losing your SSDI check. You do not have to use these nine months all at once—they can be spread across a rolling 60-month window. The only requirement is that you report your earnings to Social Security.

This period exists so you can see whether you can actually sustain work without your disability getting worse. Many people on SSDI worry that trying to work will cost them their only income if it does not work out. The Trial Work Period removes that risk for the first nine months of work.

After your nine Trial Work Periods end, you enter the Extended may be able to access Period. During this time, you can still earn above the SGA limit for up to 36 months, but Social Security will withhold your benefit check in any month you earn over SGA. Once the 36 months end, if you are still earning above SGA, your benefits stop.

The Plan to Achieve Self-Support (PASS): setting aside income for a work goal

If you have a specific work goal—returning to school, starting a business, learning a trade—you can file a Plan to Achieve Self-Support, or PASS. A PASS lets you exclude certain income and resources from the calculation that determines your benefit amount, as long as that income and those resources go toward your stated goal.

For example, if you earn $2,000 a month but $1,200 of it goes toward tuition and books for a certificate program, you can exclude that $1,200 from your countable income. Your SSDI check would be calculated as if you earned only $800. You must have a written plan, a timeline, and a realistic path to work.

A PASS is complex and requires paperwork, but it is one of the few ways to earn significantly above the SGA limit without losing benefits. You work with a Social Security representative or a work incentives planning counselor to set it up. The plan must be approved before you start setting aside the money.

Impairment Related Work Expenses (IRWE): costs of working with your disability

Impairment Related Work Expenses, or IRWE, are costs you pay specifically because of your disability to do your job. These might include a personal assistant, specialized equipment, medication needed to work, or transportation that your disability makes necessary. You can deduct these expenses from your gross earnings before Social Security calculates whether you have crossed the SGA threshold.

If you are deaf and need a sign language interpreter at work, that cost is an IRWE. If you have a mobility disability and need paratransit to get to your job, that is an IRWE. If you need a cane, a wheelchair ramp at your workplace, or medication that lets you work, those count too.

You must document these expenses and show that they are truly necessary for you to work. Social Security will not count personal grooming, regular transportation, or childcare as IRWE, even if your disability makes these things harder.

What happens if you earn over the limit

If you earn more than the SGA limit in a month and you have used up your Trial Work Period, Social Security will not pay you a benefit check that month. Your benefits do not stop permanently—they pause. Once your earnings drop below SGA again, your checks resume the following month.

If you earn over SGA for nine or more months in a row (outside your Trial Work Period), Social Security will begin a medical review to determine whether you are still disabled. They may ask for updated medical records or schedule a consultative exam. If they find that you can do substantial work, they will terminate your benefits.

The key is reporting. You must tell Social Security about your earnings within the month you earn them. If you do not report and Social Security finds out later, you will owe back the benefits they paid you. This overpayment can be large, and Social Security will ask you to repay it or will withhold future benefits to recover it.

How your benefit amount changes with work

Your SSDI check itself does not shrink because you are working. The amount you receive each month is set based on your work history before you became disabled. Work after you start receiving SSDI does not change that amount.

What changes is whether you receive a check at all. If you are in your Trial Work Period, you get your full check no matter what you earn. If you are past that period and earning above SGA, you do not get a check that month. If you have a PASS or IRWE in place, your countable earnings are lower, so you may stay under the SGA threshold even though your gross pay is higher.

Some people also receive Supplemental Security Income, or SSI, in addition to SSDI. SSI has different rules and different earnings limits. If you receive both, you need to understand how work affects each program separately.

Reporting your earnings to Social Security

You are required to report your earnings to Social Security by the end of the month in which you earn them. You can report online through your my Social Security account, by phone, or in person at your local Social Security office. If you do not report, Social Security may overpay you, and you will have to repay the money.

When you report, have your pay stubs ready. Social Security needs to know your gross earnings (before taxes), not your take-home pay. If you are self-employed, you report your net profit after business expenses.

Some people set up a work incentives representative or a benefits planning counselor to help them track and report earnings. This is especially useful if your income varies month to month or if you have a complex work situation.

Frequently Asked Questions

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

Yes, during your nine-month Trial Work Period you can earn any amount and keep your full check. After that, if you earn under the SGA limit (currently $1,550 per month), you keep your full check. If you earn above it, you do not receive a check that month, but your benefits do not stop permanently.

What if I earn money one month but not the next?

Social Security counts earnings month by month. If you earn $2,000 in January and $500 in February, you report both months separately. January is over SGA (if you are past your Trial Work Period), so no check that month. February is under, so you get your full check. This is why variable income requires careful tracking.

Do I have to report cash earnings?

Yes. Social Security wants to know all earnings, whether you receive a check, cash, or payment through an app. If you do not report and they find out, you will owe back benefits. It is safer and simpler to report everything.

What if I start a business—how do I report that?

Self-employment income is reported as net profit (revenue minus business expenses). You report it in the month you earn it, not when you receive payment. If your business is new, talk to a work incentives counselor before you start, because a PASS might protect more of your income than the standard SGA rules.

Can I work and still get Medicare?

Yes. Your SSDI Medicare coverage continues even if you earn above SGA and lose your cash benefit. You keep Medicare for at least 93 months after your Trial Work Period ends, even if your benefits stop. This is one of the strongest work incentives Social Security offers.
