You can work part-time on SSDI, but your benefits will reduce or stop if you earn above a certain monthly amount

Social Security has a specific earnings limit called the Substantial Gainful Activity (SGA) threshold. In 2024, if you earn more than $1,550 per month (or $2,590 if you are blind), Social Security counts that as substantial work, and your benefits stop. Below that amount, you keep your full benefit check each month, no matter how many hours you work.

The key word is "earn," not "work." If you work 40 hours a week but earn $1,200 a month, you are under the limit. If you work 10 hours a week and earn $1,600 a month, you are over it. Social Security looks at your gross pay before taxes.

There is also a separate rule called trial work period that lets you test whether you can work without losing benefits. During this nine-month window, you can earn any amount and keep your full SSDI check. After trial work period ends, the SGA limit kicks in.

Key Takeaways

  • You can earn up to $1,550 per month in 2024 and keep your full SSDI benefit; the exact amount changes each year.
  • Trial work period is a nine-month window where you can earn any amount without losing benefits, and it resets if you stop working for 60 months.
  • Social Security counts gross earnings, not hours worked, so a part-time job at higher pay may push you over the limit faster than a full-time job at lower pay.
  • If you go over the SGA limit, your benefits do not stop when ready—Social Security sends you a notice first and gives you a chance to report your earnings.

How the Substantial Gainful Activity limit works month to month

Every month, you report your earnings to Social Security. If you stay under $1,550, nothing changes—you receive your full SSDI payment. The limit applies to each calendar month separately, so a high-earning month does not affect the next month if your pay drops.

If you go over $1,550 in a single month, that month's benefit is reduced or withheld. Social Security does not stop your entire case. You keep your Medicare coverage, and your benefits resume the next month if your earnings drop back below the limit.

The SGA threshold increases each year. Social Security announces the new amount in October or November for the following year. You can find the current limit on the Social Security website or by calling 1-800-772-1213.

What trial work period means and when it applies

Trial work period is a nine-month test run built into SSDI. During these nine months, you can earn any amount—$500, $5,000, $10,000 per month—and Social Security will not reduce or stop your benefits. You still receive your full SSDI check every month, and you keep Medicare.

The nine months do not have to be consecutive. Social Security counts any month in which you earn $940 or more (in 2024) as a trial work month. If you earn $900 one month and $950 the next, only the second month counts. You could spread nine trial work months across two years if your earnings are uneven.

Trial work period is meant to let you test whether you can actually work without your condition getting worse. After the nine months end, the SGA limit takes over. If you then earn over $1,550 in a month, your benefits reduce or stop.

If you stop working for 60 consecutive months, trial work period resets. You get another nine-month window to test work again.

What happens if you earn over the limit

Social Security does not automatically cut off your benefits the moment you go over $1,550. Instead, you receive a notice in the mail explaining that your earnings are over the SGA limit and that your benefit for that month will be reduced or withheld. You have a chance to respond or explain your situation.

If you go over the limit for one month only, your case does not close. Your benefits resume the following month if your earnings drop back below $1,550. You do not have to reapply or restart the process.

If your earnings stay above the SGA limit for nine consecutive months, your SSDI case enters a different phase called extended may be able to access. During extended may be able to access, you can still work and earn any amount for 36 more months without losing benefits. After those 36 months, benefits stop unless your earnings drop below SGA again.

How to report your earnings to Social Security

You must report your earnings every month, even if you are under the limit. You can report online through your Social Security account, by phone at 1-800-772-1213, or in person at your local Social Security office. Many people set a calendar reminder for the same day each month to avoid forgetting.

Report your gross earnings—the amount before taxes, deductions, or tips. Include wages from a job, self-employment income, and bonuses. Do not include Social Security benefits themselves, unemployment benefits, or money from family members.

If you miss a month or report late, Social Security may overpay you. You would then owe the money back. Reporting on time prevents this problem and keeps your case in good standing.

Part-time work strategies that fit with SSDI

Some people structure their work to stay under the SGA limit. For example, working 15 hours a week at $15 per hour comes to about $975 per month—under the $1,550 threshold. Working 20 hours at $12 per hour is about $960 per month. The math depends on your hourly rate and hours.

Others use trial work period strategically. If you know you want to test a job for a few months, you can use trial work months during that period without worrying about the SGA limit. This gives you time to see whether the work affects your health or disability.

Self-employment works the same way. If you earn money from freelance work, a small business, or gig work, Social Security counts your net profit (income minus business expenses) toward the SGA limit. Keep records of your expenses so you can report accurately.

What you keep even if benefits stop

If your earnings push you over the SGA limit and your SSDI benefits stop, you do not lose Medicare automatically. You keep Medicare for at least 93 months (about 7.5 years) after your benefits end, as long as you are still disabled. This is called Medicare continuation.

If you return to work and your earnings later drop below the SGA limit, your SSDI benefits can restart without a new process. Social Security calls this expedited reinstatement. You have 60 months from the month your benefits ended to use this option.

Frequently Asked Questions

Do I have to tell my employer I am on SSDI?

No. Your SSDI status is private information between you and Social Security. You do not have to disclose it to an employer. However, if you need workplace accommodations for your disability, you may choose to tell your employer and request them under the Americans with Disabilities Act.

What if I work for a family member or get paid under the table?

Social Security counts all earnings, whether formal or informal. If you receive cash payments, barter, or work for a relative, you still must report the income. Underreporting earnings can result in overpayment, which you would have to repay, plus potential fraud penalties.

Can I work more hours if I earn less per hour?

Yes. Social Security cares about total monthly earnings, not hours worked. You could work 40 hours a week at $10 per hour (about $1,600 per month) and go over the limit, or work 30 hours a week at $12 per hour (about $1,200 per month) and stay under it. The math is what matters.

Does my SSDI benefit amount change if I work part-time?

No. Your monthly SSDI payment is fixed based on your work history and age when you started benefits. Working part-time does not change the amount you receive in months when you are under the SGA limit. You get the same check every month until earnings push you over the threshold.

What if I earn over the limit for just one month by accident?

That single month's benefit will be reduced or withheld. Your case does not close, and benefits resume the next month if your earnings drop back below $1,550. One month over the limit does not trigger extended may be able to access or any long-term consequence.
