If you're receiving Social Security Disability Insurance (SSDI) and thinking about working, the rules aren't as simple as a single dollar cap. The SSA has a structured system for how earnings interact with your benefits — and understanding it is worth the effort.
The SSA uses a standard called Substantial Gainful Activity (SGA) to measure whether your work is significant enough to affect your disability status. In 2025, the SGA threshold is $1,620 per month for most SSDI recipients. For people who are blind, the threshold is higher — $2,700 per month in 2025.
These figures adjust annually with wage index changes, so always verify the current year's amounts directly with the SSA.
If your gross monthly earnings consistently exceed the SGA limit, the SSA may determine you're no longer disabled under their definition — regardless of your medical condition. If you stay under it, your SSDI benefits generally continue unaffected.
Here's where many people get surprised: you can earn more than the SGA threshold temporarily without immediately losing benefits, thanks to the Trial Work Period (TWP).
The TWP gives you nine months (not necessarily consecutive) within a rolling 60-month window to test your ability to work. In 2025, any month in which you earn more than $1,110 counts as a trial work month. During those nine months, you keep your full SSDI benefit regardless of how much you earn.
The nine months don't have to happen back to back. You could use them spread across several years — the SSA tracks which months qualify and counts them accordingly.
Once you've used all nine trial work months, you enter the Extended Period of Eligibility (EPE) — a 36-month window during which your benefits can be turned on or off based on whether your earnings exceed SGA in any given month.
During the EPE:
After the EPE ends, earning above SGA typically triggers termination of SSDI benefits — at which point a new application would be required if your condition worsens again.
The SSA doesn't always count every dollar you earn. Impairment-Related Work Expenses (IRWEs) allow the SSA to deduct certain disability-related costs from your gross earnings before comparing them to SGA.
If you pay out of pocket for items or services that are necessary for you to work — things like specialized transportation, certain medications, medical devices, or attendant care — those costs may be deductible. This can bring your countable earnings below the SGA threshold even if your gross pay exceeds it.
The rules around what qualifies are specific, and amounts vary by situation.
| Threshold | 2025 Amount | What It Triggers |
|---|---|---|
| SGA (non-blind) | $1,620/month | Possible benefit suspension/termination |
| SGA (blind) | $2,700/month | Applies specifically to blind beneficiaries |
| Trial Work Period trigger | $1,110/month | Month counts toward your 9 TWP months |
All figures adjust annually. Confirm current amounts at SSA.gov.
The SSA's Ticket to Work program is a voluntary option for SSDI recipients between ages 18 and 64 who want to return to work. Participating in the program with an approved Employment Network or State Vocational Rehabilitation agency can provide certain protections against Continuing Disability Reviews (CDRs) while you're making progress toward employment goals.
Ticket to Work doesn't change the SGA rules, but it can add a layer of stability while you explore whether sustained work is feasible.
Not all income is treated the same. The SGA test applies to wages from work activity — it is not triggered by:
This is one of the key distinctions between SSDI and Supplemental Security Income (SSI), which has strict asset and income limits that cover a much broader range of financial resources. SSDI's SGA test is specifically about what you earn from working.
The SGA thresholds and work incentive rules apply universally — but how they play out depends on details that are specific to each person:
Someone one month into their first trial work period faces entirely different stakes than someone who used up their TWP three years ago and is now in the final months of their EPE. 💡
The numbers in 2025 are clear. How they apply to where you actually stand in the process — that's the part that requires knowing your own situation.
