2025 SSDI Trial Work Period: Monthly Earnings Limit and How It Works
If you're receiving Social Security Disability Insurance and thinking about returning to work, the Trial Work Period (TWP) is one of the most important program rules to understand. It gives you a protected window to test your ability to work without immediately losing your benefits — but the rules around earnings thresholds, timing, and what happens after the TWP ends are more nuanced than they first appear.
What Is the Trial Work Period?
The Trial Work Period is a Social Security work incentive that allows SSDI recipients to work and earn income for a set number of months while continuing to receive their full monthly benefit payment. The SSA designed this window specifically so that beneficiaries aren't penalized for attempting to re-enter the workforce.
The TWP consists of 9 months within a rolling 60-month (5-year) window. Those 9 months do not need to be consecutive. Once you've used all 9 months, the trial period ends and SSA evaluates whether your work activity constitutes Substantial Gainful Activity (SGA).
The 2025 Trial Work Period Monthly Earnings Threshold
For 2025, a month counts as a Trial Work Period service month if your gross earnings exceed $1,160. 📋
This figure adjusts annually based on changes in the national average wage index, so it's worth verifying the current year's amount directly with SSA if you're planning ahead.
A few important clarifications about this threshold:
- It is not the SGA limit. The SGA threshold for 2025 (used to evaluate work after the TWP ends) is a separate, higher figure — $1,620 per month for non-blind individuals.
- The TWP threshold applies during the protected trial window. Earning above it simply "uses" one of your 9 months; it does not stop your benefits on its own.
- If you are self-employed, SSA looks at both net earnings and the number of hours worked per month when determining whether a month counts as a TWP service month.
How the 9 Months Are Counted
Because the 9 months don't have to be consecutive, it's possible to spread them across years — but they must all fall within the same 60-month rolling period. SSA tracks each month your earnings exceed the threshold and counts backward and forward from any given month within that 5-year window.
This means someone who worked briefly above the limit two years ago could be closer to exhausting their TWP than they realize, even if they stopped working for a stretch in between.
What Happens After the Trial Work Period Ends
Once you've used all 9 TWP months, SSA enters what's called the Extended Period of Eligibility (EPE). This is a 36-month window during which your benefit status depends entirely on whether your monthly earnings exceed the SGA threshold.
| Phase | Duration | Benefit Rule |
|---|---|---|
| Trial Work Period | 9 months (within 60 months) | Full benefits regardless of earnings |
| Extended Period of Eligibility | 36 months following TWP | Benefits paid in months earnings fall below SGA |
| After EPE | Ongoing | Benefits can be reinstated via Expedited Reinstatement if disability returns within 5 years |
During the EPE, your benefits essentially switch on and off based on whether you're earning above or below SGA in a given month. Crossing the SGA line doesn't mean you're permanently off SSDI — but it does mean SSA will scrutinize that month closely.
Variables That Shape Individual Outcomes 🔍
How the TWP plays out in practice varies significantly based on a person's specific circumstances. Some of the key factors include:
Type of work and income structure. Salaried employment is calculated differently than self-employment. If you have business expenses related to your disability (called Impairment-Related Work Expenses, or IRWEs), those can be deducted from gross earnings before SSA applies the threshold — potentially keeping a month from counting as a TWP service month.
When your SSDI benefit began. If you were approved recently versus years ago, your remaining TWP months and your position within any 60-month window will differ.
Whether you're also receiving SSI. SSDI and SSI have separate work incentive rules. If you receive both, the income calculations and thresholds interact in ways that require careful tracking.
Reporting timeline. SSA requires that you report work activity promptly. Delayed reporting can result in overpayments, which SSA will seek to recover — sometimes years after the fact.
Nature of the disability. Some beneficiaries return to part-time, accommodated work well below the TWP threshold and never trigger a service month at all. Others immediately exceed the limit and begin burning through their 9 months quickly.
The Spectrum of Scenarios
Someone working part-time at modest hours might earn $900 per month — below the $1,160 TWP threshold — and accumulate no service months at all, continuing to receive full SSDI without the clock running.
Someone else who returns to a structured job earning $1,400 per month will use a service month each month they earn that amount, counting toward the 9-month limit. If they have IRWEs, the deduction might bring their countable earnings below $1,160, but that determination is specific to their documented expenses.
A third person who exhausted their TWP two years ago may already be in the Extended Period of Eligibility, where the rules and thresholds are entirely different — and the stakes of exceeding SGA are higher.
The monthly earnings figure — $1,160 in 2025 — is the same for everyone. What differs is where each person stands in the timeline, what deductions apply, and what comes next once those 9 months are used. That part isn't answered by knowing the threshold. It's answered by knowing your own situation in full.
