SSDI Trial Work Period 2023: How the TWP Works and What It Means for Your Benefits
If you're receiving SSDI and considering returning to work — or already working — the Trial Work Period (TWP) is one of the most important program rules you need to understand. It exists specifically to let beneficiaries test their ability to work without immediately losing their monthly payments. But how it actually plays out depends on timing, earnings, and what comes after the TWP ends.
What Is the SSDI Trial Work Period?
The Trial Work Period is a built-in SSA work incentive that allows SSDI recipients to work and earn income for up to 9 months without their benefits being reduced or stopped — regardless of how much they earn during those months.
Those 9 months do not need to be consecutive. The TWP window spans a rolling 60-month (5-year) period, meaning SSA looks back over the most recent 60 months to count how many trial work months you've used.
The TWP applies only to SSDI, not SSI. SSI has its own separate income rules.
What Counted as a Trial Work Month in 2023?
SSA uses an earnings threshold to determine whether a given month counts as a trial work month. For 2023, that threshold was $1,050 per month (gross earnings before deductions). If you earned at least that amount in a calendar month, SSA counted it as one of your 9 trial work months.
For the self-employed, SSA may also look at hours worked — generally more than 80 hours in a month can trigger a trial work month even if earnings are lower.
These thresholds adjust annually, so the figure that applied in 2023 may differ from the current year's threshold.
What Happens During the Trial Work Period?
During your active TWP months, you continue to receive your full SSDI benefit payment, no matter how much you earn. SSA does not offset your benefit based on income during this phase.
What SSA is doing during this time, however, is tracking your work activity. They're building a record of your earnings and employment. This matters significantly once the TWP ends.
What Happens After the Trial Work Period Ends?
Once you've used all 9 trial work months within a 60-month window, your TWP is complete. At that point, SSA evaluates whether your work activity constitutes Substantial Gainful Activity (SGA).
For 2023, the SGA threshold for non-blind SSDI recipients was $1,470 per month. For blind recipients, it was $2,460 per month. These figures also adjust annually.
After the TWP, SSA enters a phase called the Extended Period of Eligibility (EPE), which lasts 36 months. During the EPE:
- Months you earn below SGA: You receive your full benefit
- Months you earn at or above SGA: Your benefit is suspended
- If earnings drop below SGA: Benefits can be reinstated without a new application
| Phase | Duration | Benefit Impact |
|---|---|---|
| Trial Work Period | Up to 9 months (in 60-month window) | Full benefit paid regardless of earnings |
| Extended Period of Eligibility | 36 months after TWP | Benefit paid in months below SGA, suspended above SGA |
| After EPE | Ongoing | Benefits terminated if earning above SGA; reinstatement available for up to 5 years via Expedited Reinstatement |
Impairment-Related Work Expenses (IRWEs) Can Lower Countable Earnings 💡
One variable that shapes how the TWP and SGA calculations work in practice is Impairment-Related Work Expenses (IRWEs). If you pay out-of-pocket for items or services that your disability requires in order to work — such as medications, specialized equipment, or transportation — SSA may deduct those costs from your gross earnings before comparing them to the SGA threshold.
This means someone earning slightly above SGA may still have benefits continue if qualifying IRWEs bring their countable income below the threshold. Whether specific expenses qualify as IRWEs is a determination SSA makes based on documentation you provide.
How the Ticket to Work Program Connects to the TWP
SSDI recipients who are working or interested in working may also interact with the Ticket to Work program. Using your Ticket by assigning it to an Employment Network or State Vocational Rehabilitation agency can provide support services — and while your Ticket is in use and you're making timely progress, SSA generally suspends Continuing Disability Reviews (CDRs), which are periodic checks to verify you still meet the medical criteria for disability.
This doesn't pause or extend your TWP timeline, but it does add a layer of protection from medical review while you're actively engaged in work and rehabilitation planning.
Variables That Shape How the TWP Plays Out
No two beneficiaries move through the TWP the same way. Outcomes depend on:
- How many trial work months you've already used — someone who worked briefly two years ago may have fewer remaining than they realize
- Whether your condition fluctuates — inconsistent earnings month to month can mean some months count toward the TWP and others don't
- Whether you're self-employed — the hours-based test adds complexity compared to traditional wage employment
- Your awareness of reporting obligations — SSA requires you to report work activity; failing to do so can lead to overpayments that must be repaid, sometimes years later
- How your state's vocational programs interact with federal work incentives
The Gap Between the Rules and Your Situation
Understanding the TWP rules gives you a framework — but applying that framework to your own circumstances is where the real complexity lives. How many months you've used, when your 60-month window started, what counts as deductible work expenses in your case, and where you are in the EPE are all facts specific to your own SSA record. 📋
That's information SSA has on file — and information that determines whether your next paycheck triggers a trial work month, brings you closer to the end of your EPE, or falls entirely below any threshold that matters.
