If you're receiving SSDI and thinking about returning to work — or already testing the waters — the Trial Work Period (TWP) is one of the most important program rules to understand. It's also one of the most misunderstood. Many beneficiaries don't know it exists until they've already triggered it.
The Trial Work Period is a built-in protection that allows SSDI recipients to test their ability to work without immediately losing their benefits. During the TWP, you can earn any amount from work and still receive your full monthly SSDI payment — as long as you continue to meet SSA's medical disability standard.
The TWP consists of 9 months — but they don't have to be consecutive. SSA counts them within a rolling 60-month (5-year) window. Once you've accumulated 9 trial work months within that window, your TWP is used up.
SSA determines whether a month counts as a trial work month based on your earnings. For 2023, a month counts toward your TWP if you earn more than $1,050 in gross wages (or if you're self-employed, work more than 80 hours in that month).
This threshold adjusts annually, so the figure for prior or future years may differ. Any month you earn above that amount gets added to your TWP tally, regardless of how much above the threshold you go.
| Year | TWP Monthly Earnings Threshold |
|---|---|
| 2021 | $940 |
| 2022 | $970 |
| 2023 | $1,050 |
Thresholds adjust annually based on the national average wage index.
During your 9 trial work months, SSA does not apply the Substantial Gainful Activity (SGA) test to your work. In 2023, SGA is $1,470/month for non-blind individuals and $2,460/month for statutorily blind individuals. Normally, consistently earning above SGA is grounds for stopping benefits — but during the TWP, that rule is suspended.
This means you could earn $3,000 a month during a trial work month and still receive your full SSDI check. SSA is essentially giving you time to find out whether you can actually sustain work activity before making any benefit decisions.
Your medical eligibility still applies, however. If SSA conducts a Continuing Disability Review (CDR) during this period and determines your condition has medically improved, that's a separate basis for ending benefits — the TWP doesn't protect against that.
Once your 9 trial work months are used up, SSA begins evaluating your work against the SGA threshold. This begins the Extended Period of Eligibility (EPE), which lasts for 36 consecutive months after the TWP ends.
During the EPE:
This is a critical distinction. The EPE gives you a safety net during a period of variable income — you don't lose SSDI permanently just because you have a few high-earning months.
After the EPE ends, if you're still working above SGA, your benefits terminate. If you become unable to work again within 5 years of that termination, you may be eligible for Expedited Reinstatement (EXR) — a provision that lets you request benefits restart without going through the full application process again.
The Ticket to Work program often comes up alongside TWP discussions. It's a voluntary SSA program that connects SSDI and SSI recipients with employment services, vocational rehabilitation, and job training. Participating in Ticket to Work can also temporarily protect you from routine CDRs while you're working toward employment goals.
The TWP and Ticket to Work are separate mechanisms, but many people use them together when returning to work. Your TWP runs based on your earnings activity regardless of whether you've assigned your Ticket.
The TWP rules are uniform, but how they affect individual beneficiaries varies considerably depending on:
Someone who has never worked since receiving SSDI starts their TWP fresh — all 9 months are available, and they have the full 60-month window ahead of them. A modest part-time job earning just above $1,050/month starts the clock, but they still receive full benefits each of those months.
Someone who worked part-time for several months two or three years ago may have already used several TWP months without realizing it. If they return to work now and earn above the threshold, those earlier months count toward the 9.
Someone approaching the end of their 9th trial work month faces a meaningful transition — the SGA test kicks in the following month, and the EPE begins. Their benefit for any given month going forward depends directly on whether their earnings stay below SGA. 📋
How any individual's TWP interacts with their work history, current earnings, and benefit status isn't something program rules alone can answer. That's exactly the calculation — and the risk assessment — that belongs to the individual recipient and whoever they choose to consult about their specific situation.
