You won't automatically lose SSDI if you work part-time, but your payments will reduce or stop depending on how much you earn

Social Security has specific rules about how much you can earn before your SSDI payment shrinks. The key number is called substantial gainful activity, or SGA. In 2024, SGA is $1,550 per month for non-blind disabled workers (it's higher for blind workers). If you earn more than that in a month, Social Security counts that month as a month of work, and your benefits may stop.

But the rules are more forgiving than they sound. Social Security doesn't count all your income the same way. They ignore certain types of earnings, they let you test your ability to work for nine months without losing benefits, and they have a separate earnings threshold for people who are still figuring out whether they can sustain work. Understanding which rule applies to you is the difference between keeping your full payment and losing it by accident.

Key Takeaways

  • If you earn more than $1,550 per month (in 2024), Social Security will count that month as a work month, and your SSDI payment stops that month.
  • The Trial Work Period lets you earn any amount for nine months without losing benefits, as long as you report the work to Social Security.
  • After the Trial Work Period ends, you enter the Extended may be able to access Period, where you keep benefits for any month you earn less than SGA, even if you earned more in other months.
  • Impairment-Related Work Expenses (IRWE), Plans to Achieve Self-Support (PASS), and student earned income are all subtracted from your gross pay before Social Security counts it toward SGA.
  • If you stop working and your benefits end, you can restart them within five years without filing a new process.

What the Substantial Gainful Activity threshold actually means

The $1,550 monthly SGA limit (2024) is a bright line: if you earn that much or more in any calendar month, Social Security treats that month as a month of work. Your SSDI payment for that month stops. The amount doesn't matter—earning $1,550 and earning $3,000 have the same effect on your benefits that month.

The key word is earn, not receive. Social Security counts the month you perform the work, not the month you get paid. If you work in December but don't get your paycheck until January, December is the work month. This matters if you're trying to time your earnings to stay under the threshold.

The SGA amount changes every year. Social Security publishes the new figure in December for the year ahead. If you're working, ask your local Social Security office or check their website each January to confirm the current year's SGA.

The Trial Work Period: nine months of unrestricted earnings

When you first return to work on SSDI, you enter the Trial Work Period (TWP). For nine months, you can earn any amount—$100 a month or $5,000 a month—and keep your full SSDI payment. The only requirement is that you report the work to Social Security.

The nine months don't have to be consecutive. Social Security counts any nine months in a rolling 60-month window where you earned $240 or more (in 2024; this amount changes yearly). So if you work three months, stop for six months, then work again, those later months count toward your nine. You can use up your Trial Work Period slowly over five years if you want.

Many people don't realize they're in a Trial Work Period and don't report their work. Social Security finds out anyway—through tax records, wage reports, or when you renew your benefits—and then recalculates retroactively. Report your work to avoid overpayments you'll have to repay later. Contact your local Social Security office or call 1-800-772-1213 to report.

Extended may be able to access: keeping benefits while you work part-time

After your nine Trial Work Period months end, you enter the Extended may be able to access Period, which lasts 36 months. During this time, you keep your SSDI payment for any month you earn less than SGA—even if you earned more than SGA in other months.

This is where part-time work becomes sustainable. If you work part-time and earn $1,200 one month and $1,400 the next, you get your full SSDI payment both months because you stayed under $1,550. If you earn $1,600 in a third month, you lose that month's payment only. The month after, if you're back under SGA, your payment resumes.

The Extended may be able to access Period gives you a 36-month window to test whether part-time work is sustainable for you. If you stop working or your earnings drop below SGA, your benefits continue. If you later try to work again and earn over SGA, you don't lose benefits—you just lose that one month's payment.

Deductions that reduce your countable earnings

Social Security doesn't count all your income toward the SGA limit. Several categories of earnings are subtracted from your gross pay before they calculate whether you've crossed the threshold.

Impairment-Related Work Expenses (IRWE) are costs you pay to work because of your disability. If you need a personal assistant at work, specialized transportation, medication, medical devices, or therapy related to your condition, those costs reduce your countable earnings. You have to document the expense and show it's directly related to your ability to work. A wheelchair ramp at home doesn't count; a wheelchair ramp at your workplace does.

Plans to Achieve Self-Support (PASS) let you set aside income and resources for a specific work goal—retraining, education, equipment, or a business startup. While you're in a PASS, the money you set aside doesn't count as income, and it doesn't affect your SSDI or SSI. A PASS requires a written plan approved by Social Security, but it can dramatically change what you can earn and still keep benefits.

Student earned income is excluded if you're under age 22 and a full-time student. Up to $2,170 per month (2024) of your work earnings don't count toward SGA. This exclusion ends when you graduate, leave school, or turn 22, whichever comes first.

What happens when you stop working

If you work for a while and then stop, your SSDI doesn't end when ready. Social Security has a grace period of nine months after your last month of work. During those nine months, you keep your full payment even if you're not working and not earning anything. After the grace period, if you're still not working, your benefits end.

But you have a safety net: if your benefits end because you stopped working, you can restart them within five years without filing a new process. You don't have to go through the approval process again. You just contact Social Security and ask to have your benefits restarted. After five years, you'd have to file a new process and go through the approval process again.

This five-year window is important if you're testing whether part-time work is sustainable. You can try working, stop if it doesn't work out, and get your benefits back without delay or re-approval.

How Medicare and Medicaid continue while you work

Your health coverage doesn't stop when you work. If you're on SSDI, you're may have access to to Medicare after 24 months of benefits (or when ready if you have ALS). That Medicare continues even if your SSDI payment stops because you're earning over SGA. You keep Medicare as long as you're disabled, regardless of work status.

Medicaid rules vary by state. In some states, your Medicaid ends when your SSDI payment stops. In others, you can keep Medicaid even if you're earning over SGA, as long as you meet other income or resource limits. A few states have Medicaid continuation programs that let you keep Medicaid for a set period after your SSDI ends. Contact your state Medicaid office to understand your state's rules before you start working.

Reporting your work to Social Security

You must report your work to Social Security within 30 days of starting a job. You can report by phone (1-800-772-1213), in person at your local office, or online through your my Social Security account. Tell them your job title, employer name, start date, hours per week, and expected monthly earnings.

Social Security uses this information to calculate whether you're in a Trial Work Period month, whether you've crossed the SGA threshold, and whether you're using any work incentives like IRWE or PASS. If you don't report and they find out through tax records or wage reports, they'll recalculate retroactively and you may owe back an overpayment.

If your earnings or hours change, report the change. If you get a raise, report it. If you reduce your hours, report that too. Reporting is free and takes a few minutes, and it protects you from overpayments and benefit terminations you didn't expect.

Frequently Asked Questions

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

Yes, during your nine-month Trial Work Period you can earn any amount and keep your full payment. After that, during the 36-month Extended may be able to access Period, you keep your full payment for any month you earn less than $1,550 (2024). After Extended may be able to access ends, you lose that month's payment if you earn $1,550 or more that month.

What if I earn $1,200 one month and $1,600 the next?

Social Security counts each month separately. The month you earn $1,200, you get your full payment. The month you earn $1,600, you lose that month's payment. The following month, if you earn under $1,550 again, your payment resumes. Your payment doesn't reduce gradually—it either pays or it doesn't, based on that month's earnings.

Do I have to report my work to Social Security?

Yes. You must report within 30 days of starting work. Social Security will find out anyway through tax records, but reporting protects you from overpayments and helps you use work incentives correctly. Call 1-800-772-1213 to report.

What if I work and then have to stop because my condition got worse?

Your benefits don't end when ready. You have a nine-month grace period after your last month of work where you keep your full payment. If you need to stop working permanently, contact Social Security and explain. If your condition has worsened, you may be able to go back on benefits without the work incentive rules explore.

Will working affect my Medicare or Medicaid?

Medicare continues regardless of work status—you keep it as long as you're disabled. Medicaid rules vary by state. Some states end Medicaid when your SSDI payment stops; others let you keep it. Contact your state Medicaid office to understand your state's rules before you start working.
