SSDI Trial Work Period: How It Works and When It Ends

You worked hard to get your Social Security Disability Insurance (SSDI) benefits. Now you're feeling a little better and wondering if you can try going back to work — without losing everything you fought for.

That's exactly what the Trial Work Period (TWP) is designed for. The Social Security Administration (SSA) gives you a window to test whether you can return to work without immediately cutting off your benefits. But the rules are specific, the clock is always ticking, and a misstep can cost you.

This article explains exactly how the Trial Work Period works, when it ends, what happens next, and what you need to watch out for.

What Is the SSDI Trial Work Period?

The Trial Work Period is a program that lets SSDI recipients test their ability to work while still receiving their full monthly disability benefits — regardless of how much they earn during that test period.

You get 9 months of trial work. During those months, you can work and earn as much as you're able to, and the SSA will continue paying your SSDI benefits in full.

There's an important catch: those 9 months don't have to be consecutive. They're counted within a rolling 60-month (5-year) window. So if you work for three months, stop, then work again two years later, those months still count toward your 9.

Who Is Eligible for the Trial Work Period?

You're eligible if you're currently receiving SSDI benefits and you begin working. The TWP does not apply to people receiving Supplemental Security Income (SSI) — SSI has different rules for working.

You also need to have been on SSDI long enough for the entitlement period to have begun. In most cases, if you're receiving SSDI payments, you automatically have access to the TWP when you decide to try working.

How Does the SSA Define a "Trial Work Month"?

Not every month you work automatically counts as a Trial Work Month. The SSA uses an earnings threshold to decide whether a month counts.

In 2024, a month counts as a trial work month if you earn more than $1,110 (gross, before taxes). If you're self-employed, the threshold is either $1,110 in net earnings or 80 or more hours of work in that month — whichever comes first.

These thresholds are adjusted slightly each year based on national wage averages. A few hundred dollars of part-time income in a month won't necessarily trigger a trial work month — but anything approaching or exceeding that threshold will.

What Counts as "Earnings" Under the TWP?

The SSA counts:

They do not count investment income, rental income, or unearned income toward the trial work threshold. It's specifically about work activity.

What Happens After You Use All 9 Trial Work Months?

Once you've used up all 9 trial work months within a 60-month window, the SSA evaluates whether your work qualifies as Substantial Gainful Activity (SGA).

In 2024, SGA means earning more than $1,550 per month (or $2,590 if you're blind). This is a separate threshold from the trial work threshold.

Here's how the evaluation breaks down after your Trial Work Period ends:

The Extended Period of Eligibility

After your Trial Work Period ends, you enter a 36-month Extended Period of Eligibility (EPE). Think of it as a safety net.

During those 36 months, the SSA will pay your full SSDI benefit in any month where your earnings fall below the SGA level. If you earn above SGA, you won't receive a benefit check that month. But if you drop below SGA again — due to illness, injury, or reduced hours — your benefits can be reinstated without a new application.

This is a critical protection that many SSDI recipients don't know about. If your health forces you to stop working within that 36-month window, you can get back on benefits quickly.

The 5-Year Lookback Window: Why Timing Matters

The 60-month rolling window is one of the most misunderstood parts of the Trial Work Period. Here's why it matters:

Your 9 trial work months don't reset after you use them. They're tracked over any consecutive 60-month period. So if you used 6 trial work months several years ago, you may only have 3 remaining — even if years have passed since then.

The SSA will look back across the last 60 months to count how many months you've already used. If you haven't tracked this yourself, your SSA file will have a record. You can request a copy of your earnings record and benefit history by contacting the SSA directly or logging into your my Social Security account at ssa.gov.

Example: How the 60-Month Window Works in Practice

Imagine you returned to part-time work in January 2021 and used 4 trial work months before stopping in May 2021. Then in March 2024, you try working again. Those 4 months from 2021 are still within the 60-month window in 2024. You'd have 5 trial work months remaining, not a fresh 9.

By January 2026, the first months from 2021 would start rolling off the 60-month window — and new trial work months would become available. Timing your return to work with this window in mind can make a significant difference.

Work Incentives That Work Alongside the TWP

The Trial Work Period doesn't operate in isolation. The SSA has built in several other work incentives that apply during and after your TWP.

Impairment-Related Work Expenses (IRWE)

If you pay out-of-pocket for items or services that you need because of your disability — and those costs enable you to work — the SSA may deduct those expenses before calculating whether your earnings exceed SGA.

Examples include specialized transportation, certain medications, medical equipment, or attendant care. These deductions can meaningfully lower your countable earnings and help you stay below the SGA threshold.

Subsidies and Special Conditions

If your employer gives you special accommodations, extra supervision, or only expects you to work at reduced capacity because of your disability, the SSA can subtract a "subsidy" from your earnings when calculating SGA. What you're actually paid may be higher than what the SSA counts.

Unsuccessful Work Attempts

If you try to work but have to stop — or significantly reduce your work — within 6 months because of your medical condition, the SSA may classify it as an Unsuccessful Work Attempt (UWA). Work attempts that qualify as UWAs may not count against you for SGA purposes and may not be counted as trial work months. There are specific criteria the attempt must meet, so document everything if this applies to you.

What You Must Report to the SSA

While the Trial Work Period is a right you're entitled to, the responsibility to report your work activity falls entirely on you.

You are required to report:

Failing to report work activity — even unintentionally — can result in overpayments that the SSA will demand back. These overpayments can run into thousands of dollars and are extremely difficult to discharge. Report every change promptly, in writing, and keep copies.

You can report work activity through your local SSA office, by phone at 1-800-772-1213, or through your my Social Security online account.

What Happens If Your Benefits Are Terminated After the TWP?

If the SSA determines you've been earning above SGA consistently after your Trial Work Period and Extended Period of Eligibility, your SSDI benefits can be terminated. This doesn't mean you're out of options.

Expedited Reinstatement

If your benefits ended because of work, and within 5 years of termination your medical condition forces you to stop working again, you can request Expedited Reinstatement (EXR). You don't have to file a brand new application and go through the full approval process again.

Under EXR, the SSA can provide provisional benefits for up to 6 months while they review your case. If you're approved, your benefits resume. If not, you keep the provisional payments and generally don't have to repay them.

This is a significant protection that many former recipients don't know exists. If your health deteriorates and you've lost SSDI benefits in the past 5 years, explore EXR before assuming you have to start over.

Frequently Asked Questions About the SSDI Trial Work Period

How do I know how many trial work months I've already used?

The SSA tracks every month you've earned above the trial work threshold. To find out how many you've used, contact the SSA at 1-800-772-1213 and ask for a review of your work activity record, or log into your my Social Security account at ssa.gov. You can also request this information in writing from your local SSA field office. If you're working with a disability advocate, they can request this on your behalf and help you interpret the records.

Can I lose my SSDI benefits during the Trial Work Period even if I'm still disabled?

In most cases, no — not for work activity alone. During your 9 trial work months, the SSA pays your full benefits regardless of earnings. However, the SSA can still review your medical condition at any time through a Continuing Disability Review (CDR). If they determine your condition has medically improved to the point where you no longer meet the disability standard, your benefits could end for medical reasons — separate from the trial work rules. This is why it's important to maintain your medical documentation even while working.

What happens if I earn just slightly over the SGA limit after my trial work period ends?

Once your Trial Work Period is exhausted and you're in the Extended Period of Eligibility, earning over SGA in a given month means you won't receive your SSDI payment for that month. But you won't lose your benefits permanently right away. The SSA typically conducts a review, and if your earnings consistently exceed SGA for several months, they'll begin termination proceedings. During the EPE, the key is that any month you fall below SGA, your benefits resume automatically — you don't have to reapply. Keep careful records of your monthly earnings so you know where you stand relative to the SGA threshold.

Does the Trial Work Period apply if I receive both SSDI and SSI?

If you receive both SSDI and Supplemental Security Income (SSI), the Trial Work Period applies only to your SSDI benefits. SSI has its own separate rules for work activity, including different earned income exclusions and the $1-for-$2 benefit reduction formula. Because the two programs calculate work differently, it's very easy to trigger unintended consequences by not accounting for both sets of rules. If you receive both programs, consult with a disability advocate or benefits counselor before starting any work activity to avoid an overpayment situation.

If I used all my trial work months years ago, can I ever get them back?

The 9 trial work months are tracked over a rolling 60-month window — so months do eventually age out of that window. As old trial work months roll outside the 60-month lookback period, new trial work months theoretically become available again. However, this depends on when those earlier months occurred relative to today. It does not mean you start completely fresh — it means the specific months counted more than 5 years ago no longer factor into the current 60-month window. The SSA will calculate this based on your actual earnings record. If you're trying to plan around this, ask an advocate to help you map your specific timeline before you begin working.

Can I work part-time without triggering the Trial Work Period?

Yes. If your monthly gross earnings stay below the trial work threshold — $1,110 in 2024 — that month does not count as a trial work month. Many SSDI recipients do very limited part-time work without triggering the TWP at all. However, you must still report all work activity to the SSA, regardless of earnings level. Even if a month doesn't count as a trial work month, the SSA needs to know you're working. The reporting requirement never goes away. Failing to report even low-level work can result in an overpayment finding if the SSA later discovers the activity through a wage match with the IRS.

The Bottom Line

The Trial Work Period is a genuine opportunity — the SSA built it specifically so SSDI recipients aren't forced to choose between trying to get better and protecting their benefits. But the rules are narrow, the timelines are firm, and the reporting requirements are strict.

If you're thinking about returning to work while on SSDI, or if your benefits have been affected by past work activity, talking to a disability advocate before you act is the smartest move you can make. The difference between a well-planned return to work and an accidental overpayment can be thousands of dollars.

If your SSDI benefits have already been denied or reduced, and you believe work-related issues were mishandled in your case, you may have grounds to appeal. You have 60 days from any denial notice to file — and waiting costs you.
