The trial work period gives SSDI beneficiaries nine months, not necessarily in a row, within a rolling 60-month window to test work while keeping full benefits. For 2026, a month counts when gross earnings exceed $1,210. After the ninth month, a 36-month extended period of eligibility decides month by month whether checks continue.
What is the trial work period for SSDI?
Under Social Security Disability Insurance (SSDI), you can work at any earnings level for nine trial work months and still receive your full check. SSDI is the program built on your own payroll tax record, and 20 CFR 404.1592 describes the trial work period as a period during which you may test your ability to work and still be considered disabled.
It is not a probation SSA puts you on. It is a test you run on yourself, and SSA keeps count. Most people reach it through SSDI on their own work record, and the regulation also extends it to people receiving child's benefits based on disability and to certain disabled widows, widowers and surviving divorced spouses.
Supplemental Security Income (SSI), the needs-based program, has no trial work period. The Red Book says Section 1619(a) eliminates the need for a trial work period or extended period of eligibility under SSI, because SSI eligibility can continue as long as you meet the basic requirements. If you are still applying, our SSDI claims page covers how entitlement starts in the first place.
Which months count toward your nine SSDI trial work months
A month counts when your gross earnings pass the trial work threshold or, if you are self-employed, when you work more than 80 hours in the business or your net earnings pass that threshold. For 2026, that threshold is $1,210 a month, according to SSA's trial work period amounts. For employees the test is gross pay, the figure before taxes and deductions come out.
The nine months do not have to be consecutive. Under SSA's rule, the ninth month has to fall within a period of 60 consecutive months, which works like a five-year lookback that moves forward with the calendar. Each time you have a month over the threshold, SSA looks across the 60 months ending with that month. If nine service months sit inside that window, the trial work period is complete. A month you worked more than five years earlier has already dropped out of the count.
An example makes the arithmetic plain. Say you work three months over the threshold in one year, stop for a while, and then work six more months over it two years later. All nine fall inside one 60-month window, so the trial work period ends with the ninth.
SSA sets this threshold below the SGA line. A month can use up one of your nine trial months even though the same earnings would not count as substantial gainful activity.
Do SSDI benefits stop during the trial work period?
No. Earnings during the trial work period do not reduce your SSDI check, and SSA will not treat that work as showing your disability ended until all nine months are used. Two limits come with that protection.
- The trial work period can end early if new evidence shows you are no longer disabled, even if you have not worked nine months.
- Once it is complete, SSA may look back at the work you did during it when deciding whether your disability ended.
The unsuccessful work attempt rule, which sets aside short jobs that ended because of your impairment, does not apply during the trial work period, according to the Red Book's SSDI employment supports page. It can apply later, during the extended period of eligibility.
You still report every month of work. The trial work period protects the check, but it does not pause the duty to tell SSA when you start a job, change employers or earn more. Our overview of working on disability covers how and when to report.
How the SSDI extended period of eligibility works
The extended period of eligibility starts the month after your ninth trial work month, and its first 36 months are a reentitlement period in which each month's earnings decide whether you are paid. The steps run in this order under 20 CFR 404.1592a:
- The first month your work reaches the substantial gainful activity (SGA) level after the trial work period is the month your disability ceases. SSA pays that month and the two months after it, whether or not you keep working at that level.
- After those three months, SSA stops the check for any month in which you do SGA.
- For any month inside the 36 months when your work falls below SGA, SSA pays the check without a new application.
- If SSA already found your disability ceased because of work during those 36 months, the first month of SGA-level work after they end terminates entitlement.
For 2026, SGA is $1,690 a month, or $2,830 a month if you are statutorily blind, per SSA's 2026 cost-of-living fact sheet. Our guide to substantial gainful activity explains how SSA measures earnings against that line.
For payment months after SSA has found that your disability ceased because of SGA, SSA does not average your earnings. It looks at each month on its own, which works like a light switch rather than a thermostat. One strong month costs one check, and a slow month after it can bring the check back.
Restarting SSDI benefits through expedited reinstatement
Expedited reinstatement can restart SSDI if work ended your benefits and your condition later stops you from working, as long as SSA receives your request within 60 months of the month entitlement ended. Under 20 CFR 404.1592c and 404.1592d, these conditions apply:
- Your prior entitlement ended because you did SGA.
- SSA receives your request within the 60-month period that begins with the month your entitlement terminated, or later if SSA finds good cause for the delay.
- You are not able to do SGA because of your medical condition in the month you file.
- Your current impairment is the same as or related to the impairment SSA used for your prior entitlement.
- You meet the disability standard SSA uses in medical improvement reviews.
While SSA reviews the request, it can pay up to 6 consecutive months of provisional cash benefits and Medicare. The provisional amount equals the last monthly benefit payable during your prior entitlement, adjusted for cost-of-living increases. Payments end sooner if SSA issues its decision, if you do SGA, or if you reach full retirement age.
The 60-month clock runs from the month entitlement ended, not from the month you stopped working. Keep the termination notice with your pay records so that date is easy to prove.
Questions People Ask About This
When does my trial work period start?
The Red Book says the trial work period cannot begin before the later of two months: the first month you are entitled to SSDI, or the month you filed your application. Work above the threshold before that point does not use up any of your nine trial months. Months after it count the same way whether you work for an employer or for yourself, using the earnings test or the 80-hour test.
Can I keep Medicare after my SSDI checks stop because of work?
Yes, for a long time. The Red Book says Medicare coverage can continue for at least 93 consecutive months after the trial work period ends, as long as your disability continues. After premium-free coverage ends, you may buy Part A and Part B, and you may qualify for a 45 percent reduction in the Part A premium.
Do I have to pay back provisional benefits if expedited reinstatement is denied?
Generally not. Under 20 CFR 404.1592e, provisional benefits paid before SSA decides are not recovered as an overpayment unless SSA determines you knew, or should have known, that you did not meet the requirements. Payments made after SSA has already found you ineligible are different and can be recovered. SSA's decisions about provisional benefits themselves are not open to appeal.
