What the Trial Work Period Does

The Trial Work Period is a nine-month window during which you can work and earn any amount of money without losing your SSDI cash benefit. Social Security counts a month toward your nine months whenever you earn $940 or more in that month—the threshold changes each year, but the rule stays the same. You do not have to tell Social Security in advance that you are starting work; you report your earnings when they ask, usually on a form called the Earnings Report.

The purpose is straightforward: to let you test whether you can sustain work before your benefits stop. You keep your full monthly check no matter how much you earn during these nine months. Medicare continues without interruption. The only requirement is that you report your work activity honestly when Social Security asks.

Key Takeaways

  • During your nine-month Trial Work Period, you keep your full SSDI payment and Medicare even if you earn thousands of dollars per month.
  • A month counts toward your nine months only if you earn $940 or more that month; months with lower earnings do not count.
  • You do not need permission to start work—you straightforward report your earnings to Social Security on the form they send you.
  • After your nine months end, the Substantial Gainful Activity (SGA) earnings limit kicks in; if you earn above that limit, your benefits stop.
  • If you stop working and your earnings drop below SGA, your benefits can restart without a new process, but only within 36 months of when your Trial Work Period ended.

How Months Count Toward Your Nine

Social Security counts a calendar month toward your Trial Work Period only if you earn $940 or more during that month. This is the trial work month threshold, and it changes each January. If you earn $939 in a month, that month does not count. If you earn $1,500 in a month, it counts as one month—not more, no matter how much over $940 you go.

The nine months do not have to be consecutive. You could work four months, stop for two months, then work five more months. Only the months in which you earned $940 or more count. This flexibility is intentional: it lets you test work, step back if your condition flares, and resume without losing ground.

Social Security tracks which months count on your record. You can call 1-800-772-1213 and ask them to tell you how many trial work months you have used so far. They will give you the exact number and the dates of the months that counted.

What Happens When Your Nine Months End

Once you have used all nine trial work months, the Substantial Gainful Activity (SGA) limit takes over. For 2024, SGA is $1,550 per month for non-blind workers and $2,590 for blind workers. If you earn above your SGA limit in any month after your trial work period ends, your SSDI payment stops for that month. The exact SGA amount changes each year on January 1.

This is not a cliff. If you earn $1,549 in a month, you get your full check. If you earn $1,551, your check stops. If you then earn $1,400 the next month, your check resumes. Your benefits turn on and off based on whether you cross the SGA line each month, not on an annual total.

Many people assume their benefits end permanently once they work above SGA. They do not. As long as you remain disabled under Social Security's definition, your benefits can restart whenever your earnings drop back below SGA—but only within 36 months of when your trial work period ended. After 36 months, you would need to file a new process.

Reporting Your Earnings to Social Security

Social Security will send you an Earnings Report form, usually by mail, asking you to report what you earned in the previous month. You fill in your gross wages (before taxes), sign it, and mail it back. Some people receive the form every month; others receive it less frequently depending on their work pattern.

You can also report earnings by phone at 1-800-772-1213 or online through your my Social Security account at ssa.gov. If you have a work incentive representative or a benefits planning service, they can help you report, but the responsibility to report is yours. Failing to report earnings can result in an overpayment—money Social Security paid you that you were not may have access to to—and you will have to repay it.

Keep pay stubs or a record from your employer showing your gross monthly earnings. If you are self-employed, keep records of your income and expenses. Social Security may ask to see these documents, and having them ready speeds up the process.

How Self-Employment Earnings Count

If you are self-employed, Social Security counts a trial work month based on either hours worked or net income, whichever method is more favorable to you. For 2024, a trial work month is either (1) a month in which you work 80 or more hours in your business, or (2) a month in which your net profit is $940 or more.

Net profit means your business income minus your business expenses. If you gross $2,000 but spend $1,200 on supplies and overhead, your net profit is $800—which would not count as a trial work month. Social Security wants to see the actual profit you keep, not the total money that passes through your business.

Self-employment is more complex to report because you have to track both hours and income. A benefits planning service or work incentive representative can help you understand how your specific business structure affects your trial work months. Many of these services are free through your state vocational rehabilitation agency or a Work Incentive Planning and information (WIPA) project.

What Happens to Medicare During and After Trial Work

Your Medicare coverage does not change during your nine-month trial work period. You keep Medicare Part A (hospital insurance) and Part B (medical insurance) for free, regardless of how much you earn. This is one of the most valuable parts of the trial work period: you can test work without risking your health insurance.

After your trial work period ends, Medicare continues even if your SSDI cash benefit stops because you earned above SGA. You stay on Medicare as long as you remain disabled under Social Security's rules. If Social Security later determines you are no longer disabled, Medicare ends 24 months after your benefits stop. But during those 24 months, you keep coverage even if you are working and earning well above SGA.

This extended Medicare coverage is called the Medicare Continuation Period. It is one reason the trial work period is so important: it gives you a runway to build work history and income while keeping both your cash benefit and your health insurance intact.

Common Mistakes and How to Avoid Them

The most common mistake is not reporting earnings at all. Some people think that if they do not tell Social Security, the agency will not find out. Social Security cross-matches earnings records with the IRS and the Social Security Administration's own wage records. Unreported earnings will be discovered, and you will owe back the benefits you should not have received.

Another mistake is assuming that once you work above SGA, your benefits are gone forever. They are not. If you stop working or drop below SGA, you can get your benefits back without reapplying—as long as you are still within 36 months of the end of your trial work period. Many people give up and do not realize they could have restarted benefits.

A third mistake is not understanding the difference between trial work months and SGA. Some people think they have nine months to earn any amount, then benefits stop permanently. In reality, you have nine months where earnings do not matter at all, and then an indefinite period where only the SGA limit matters. You can work above SGA for years after your trial work period ends, as long as you understand that your benefits will stop in months when you cross that line.

Frequently Asked Questions

Can I use my trial work months all at once, or do they have to be spread out?

You can use them however you want. You could work nine consecutive months and use all nine trial work months in a row, or you could work one month, stop for six months, then work eight more months. Only the months in which you earn $940 or more count, so the timing is entirely up to you and your condition.

What if I earn $940 in one month and then lose my job the next month?

That first month counts as one trial work month. The second month, if you earn nothing, does not count. Your trial work period is still active, and you can go back to work whenever you are ready. The nine months are about the months you actually work above the threshold, not about a calendar important date.

Do I lose my trial work period if I go back to work after stopping?

No. Your trial work period is a one-time benefit that stays with you. If you use six months, stop working for a year, then go back to work, you still have three trial work months left. The months you have already used are gone, but the unused months remain available until you use them all or until 36 months pass after your trial work period ends.

What if I earn exactly $940 in a month—does that count?

Yes. The threshold is $940 or more. If you earn $940, that month counts as one trial work month. If you earn $939.99, it does not count. The exact threshold changes each January, so check with Social Security if you are close to the line.

Can I work part-time during my trial work period and still keep my full benefit?

Yes. The trial work period does not care how many hours you work or how much you earn—only whether you earn $940 or more in a month. You could work one day a week and earn $2,000 in a month, and that month would count. You could work 40 hours a week and earn $800, and that month would not count. Earnings are what matter, not hours.
