Work and SSDI: What the Earnings Rules Actually Are

Social Security Disability Insurance (SSDI) does not stop the moment you earn money. Instead, Social Security uses specific dollar thresholds and work incentive programs to let you test your ability to work without losing your entire benefit when ready. The key is understanding which earnings count, what thresholds trigger a review, and which work incentive programs can protect your benefits while you earn.

The basic rule: if you earn more than the monthly substantial gainful activity (SGA) amount, Social Security will assume you are no longer disabled and may stop your benefits. But "more than" does not mean "any amount over"—there are months of grace, trial work periods, and programs designed to let you keep working and keep some or all of your benefit.

Key Takeaways

  • The SGA threshold for 2024 is $1,550 per month for non-blind beneficiaries; if you earn more than this in a month, that month counts toward a review of your disability status.
  • The Trial Work Period lets you earn any amount for nine months without losing benefits, though you must report your earnings to Social Security.
  • After the Trial Work Period ends, the Extended Period of may be able to access protects your benefits for 36 more months if your earnings stay below SGA in those months.
  • Work incentive programs like Impairment Related Work Expenses (IRWE) and Plans to Achieve Self-Support (PASS) can reduce your countable earnings and extend your benefit payments.
  • The SGA threshold changes each year, so you must check the current amount before you start working or increase your hours.

The Substantial Gainful Activity (SGA) Threshold and What It Means

Social Security defines substantial gainful activity as work that produces earnings above a set monthly amount. For 2024, that amount is $1,550 per month for people who are not blind. (The threshold is higher for blind beneficiaries—$2,590 in 2024—but the logic is the same.) This number changes every year because it is tied to the national average wage index.

If you earn more than $1,550 in a single month, Social Security counts that month as a "work month." Nine work months in a row, or scattered across 60 months, can trigger a medical review of your disability status. If the review finds you can work, your benefits stop. But you do not lose benefits when ready after one month over the threshold—the system is designed to give you time to test whether you can actually sustain work.

Earnings that count toward SGA include wages from a job, net income from self-employment, and certain other forms of income. Earnings that do not count include student earned income (if you are under 22), certain impairment-related work expenses, and income from certain work incentive programs.

The Trial Work Period: Nine Months to Earn Without Losing Benefits

The Trial Work Period is a nine-month window during which you can earn any amount—$100 a month or $5,000 a month—and keep your full SSDI benefit. The catch is that you must report your earnings to Social Security, and the nine months do not have to be consecutive. A "work month" during the Trial Work Period is any month in which you earn $240 or more (this threshold also changes annually).

Once you have used nine work months, the Trial Work Period ends. At that point, Social Security looks at your average earnings over the past 60 months. If your average is above SGA, your benefits stop. If your average is below SGA, you move into the Extended Period of may be able to access.

You do not have to use all nine months at once. If you work for three months, stop for six months, then return to work, those three months count toward your nine. This gives you flexibility to test different jobs or work schedules without the pressure of a single important date.

The Extended Period of may be able to access: 36 More Months of Protection

After your Trial Work Period ends, you enter the Extended Period of may be able to access (EPE), which lasts 36 months. During the EPE, you keep your SSDI benefit in any month your earnings stay below the SGA threshold. If you earn above SGA in a month, you do not receive a benefit that month, but your benefit does not stop permanently—it resumes the next month if your earnings drop back below SGA.

The EPE is meant to give you a longer runway to see whether you can sustain work. Some people use it to gradually increase their hours or test a new job. Others use it to stay in the workforce while their benefit acts as a safety net in months when work is slow or they take unpaid leave.

After the 36-month EPE ends, the rules change again. If you are still working and earning above SGA, your benefits stop. But you can still return to SSDI if your medical condition worsens or your work ends—you have a five-year window to restart benefits without a new process, though you will need a medical review.

Work Incentive Programs That Reduce Your Countable Earnings

Impairment Related Work Expenses (IRWE) are costs you pay to work because of your disability. Examples include special transportation to get to work, medication or medical equipment you need only to work, or the cost of a personal attendant who helps you at the job. You can deduct these expenses from your gross earnings before Social Security calculates whether you have exceeded SGA. If you earn $2,000 a month but spend $600 on disability-related work costs, your countable earnings are $1,400—below the SGA threshold.

Plans to Achieve Self-Support (PASS) let you set aside income and resources for a specific work goal—retraining, starting a business, or buying equipment. Money in a PASS plan does not count toward your earnings or your resource limit, and it does not reduce your SSDI benefit. A PASS is complex to set up and requires Social Security approval, but it can protect a large portion of your earnings if your goal is substantial.

Other programs include the Student Earned Income Exclusion (if you are under 22, some of your work income does not count), Blind Work Expenses (if you are blind), and the Expedited Reinstatement program (which lets you return to SSDI quickly if you try to work and it does not work out). Each has specific rules about what counts and how long it lasts.

How to Report Your Earnings to Social Security

You must report your earnings to Social Security every month you work. You can report online through your my Social Security account, by phone, or by mail. Social Security uses your reports to determine whether you have exceeded SGA and to calculate your benefit for months when you earn above the threshold but below a higher limit (called the "substantial earnings level").

If you do not report earnings, Social Security may overpay you, and you will owe the money back. If you report late, the same thing can happen. Set a reminder to report by the end of each month you work, or ask your employer to help you track your hours and pay.

If you are self-employed, the rules are more complex because Social Security counts your net profit (income minus business expenses), not your gross revenue. Keep detailed records of income and expenses, and consider working with a representative who understands self-employment and SSDI.

What Happens If You Earn Above SGA

If you earn above SGA after your Trial Work Period and Extended Period of may be able to access end, Social Security will stop your benefit. But stopping your benefit does not mean you lose SSDI permanently. You can return to SSDI within five years if your medical condition worsens, your work ends, or your earnings drop below SGA for a sustained period. You do not have to file a new process—Social Security can reinstate your benefits under the Expedited Reinstatement program.

If you are close to the SGA threshold and worried about losing benefits, talk to a Social Security representative or a work incentive planning specialist (often called a "WIPA" counselor) before you increase your hours or take a higher-paying job. They can help you understand which work incentive programs might protect your benefits and what your earnings would need to be to stay within the rules.

Frequently Asked Questions

Does part-time work count differently than full-time work?

No. Social Security counts only your total monthly earnings, not how many hours you work. You could earn $1,600 in one week and have that month count as a work month, or earn $1,600 spread across four weeks and have the same result. What matters is the total, not the schedule.

Can I work for more than one employer and still keep my benefits?

Yes. Social Security adds up all your earnings from all jobs in a month. If your combined earnings exceed SGA, that month counts as a work month. But you can work multiple part-time jobs as long as your total stays below the threshold, or use the Trial Work Period and Extended Period of may be able to access to earn above it.

What if I get a bonus or back pay from my job?

Bonuses and back pay count as earnings in the month you receive them, not the month you earned them. If you get a large bonus, that month's earnings could exceed SGA. Report it to Social Security in the month you receive it so they can count it correctly.

Do I lose my Medicare or Medicaid if I earn too much?

Medicare coverage continues for at least 93 months after your Trial Work Period ends, even if your benefits stop. Medicaid rules vary by state. Some states continue Medicaid as long as your earnings stay below a certain level; others use different rules. Contact your state Medicaid office to understand how your work will affect your coverage.

What is the difference between SGA and the substantial earnings level?

SGA is the threshold that determines whether a month counts as a work month. The substantial earnings level is higher—in 2024, it is $3,822 for non-blind beneficiaries. If you earn between SGA and the substantial earnings level in a month after your Trial Work Period, you receive a reduced benefit rather than no benefit. This gives you a middle ground where you can earn more and still receive some payment.
