If you're receiving SSDI benefits and thinking about returning to work, the Trial Work Period (TWP) is one of the most important protections the program offers. It lets you test your ability to work without immediately losing your benefits — but it comes with specific dollar thresholds that determine when a month "counts" against you. Understanding those amounts, and how they're applied, is essential before you take your first paycheck.
The Trial Work Period is a window SSA provides to SSDI recipients who want to attempt returning to work. During this period, you can earn money — even substantial money — and still receive your full SSDI benefit payment each month.
The TWP lasts for 9 months total, but those 9 months don't have to be consecutive. SSA counts them within a rolling 60-month (5-year) window. Once you've used all 9 months, the trial period ends and a different set of rules takes over.
The critical question is: which months count as trial work months? That's where the dollar amount comes in.
SSA uses a monthly earnings threshold to decide whether any given month qualifies as a trial work month. For 2024, that threshold is $1,110 per month in gross earnings (before taxes or deductions).
If you earn $1,110 or more in a calendar month, SSA counts it as one of your 9 trial work months — regardless of whether your benefits are affected.
If you earn less than $1,110 in a month, that month does not count as a trial work month, and the clock doesn't move.
This threshold adjusts annually based on changes to the national average wage index, similar to how other SSA figures are updated. It has risen steadily over the years:
| Year | TWP Monthly Threshold |
|---|---|
| 2020 | $910 |
| 2021 | $940 |
| 2022 | $970 |
| 2023 | $1,050 |
| 2024 | $1,110 |
Always verify the current year's figure directly with SSA, as it updates each January.
For employees, the threshold is straightforward: gross monthly wages.
For self-employed individuals, SSA looks at either:
Whichever measure applies, crossing either threshold counts the month. Self-employed SSDI recipients need to track both their income and their hours carefully.
Once you've used all 9 trial work months, SSA doesn't immediately cut off your benefits. You move into a different phase called the Extended Period of Eligibility (EPE), which lasts 36 months.
During the EPE, your benefits are evaluated against the Substantial Gainful Activity (SGA) threshold — a separate and higher dollar figure. For 2024, SGA is $1,550 per month for non-blind recipients and $2,590 for blind recipients.
In any EPE month where your earnings fall below SGA, you receive your full benefit. In any month where earnings are at or above SGA, your benefit is suspended — but not permanently terminated. If your earnings drop back below SGA during the 36-month window, benefits can be reinstated without a new application.
This distinction between TWP and EPE thresholds matters significantly. The TWP amount ($1,110) is lower than SGA ($1,550), which means there's a range — roughly $440 per month in 2024 — where you're using up trial work months but not yet triggering a benefit suspension.
The Trial Work Period doesn't exist in isolation. It's part of a broader set of SSDI work incentives that can interact in important ways:
Ticket to Work — Assigning your Ticket to an approved Employment Network can provide additional protections and may affect how SSA reviews your work activity during the TWP.
Impairment-Related Work Expenses (IRWEs) — Costs you pay out-of-pocket for items or services that allow you to work (specialized equipment, certain medications, transportation to treatment) can be deducted from your gross earnings before SSA applies the TWP threshold. This can affect whether a month counts at all.
Subsidies — If an employer provides you with extra support — more supervision, fewer duties, accommodations beyond what's standard — SSA may count only the fair market value of your work, which could reduce the effective earnings figure used to assess your TWP month.
These deductions and adjustments apply differently depending on your employment situation, the nature of your disability, and how SSA documents your case.
The TWP dollar amount is fixed by SSA policy, but how it plays out for any individual depends on several layers:
The threshold itself is a single, published number. But whether a given month counts, how deductions affect that calculation, and what happens when the TWP ends are questions that resolve differently for every recipient.
Knowing the amount is the starting point — applying it correctly to an actual work situation is where the real complexity lives.
