If you're receiving Social Security Disability Insurance — or trying to keep it — few numbers matter more than the Substantial Gainful Activity (SGA) threshold. In 2025, that number determines whether SSA considers you capable of supporting yourself through work, which directly affects whether you can qualify for or continue receiving SSDI benefits.
Substantial Gainful Activity is SSA's term for a level of work activity and earnings significant enough to suggest a person is not, under program rules, fully disabled. The agency uses a monthly earnings threshold to measure this.
If you earn above the SGA limit, SSA may determine you are engaging in SGA — which can result in denial of a new claim or termination of existing benefits, depending on where you are in your SSDI timeline.
This threshold applies specifically to SSDI, not SSI. SSI uses a different income calculation entirely.
SSA adjusts SGA thresholds annually based on changes in the national average wage index. For 2025, the figures are:
| Category | Monthly SGA Limit (2025) |
|---|---|
| Non-blind individuals | $1,620/month |
| Blind individuals | $2,700/month |
The higher threshold for blind individuals reflects a long-standing statutory distinction in the Social Security Act.
These are gross earnings figures, not net. SSA looks at what you earn before taxes, though certain work-related expenses — called Impairment-Related Work Expenses (IRWEs) — can sometimes be deducted from countable earnings.
The SGA limit doesn't work the same way across every phase of an SSDI claim or benefit period. Where you are in the process shapes how SSA applies this number.
When you first apply for SSDI, SSA checks whether you are currently engaging in SGA. If your monthly earnings exceed $1,620 (for non-blind applicants in 2025), SSA will typically deny your claim at step one of the five-step sequential evaluation process — before even reviewing your medical records.
This makes SGA the first and fastest disqualifier in an SSDI application.
Once you're approved and receiving SSDI, the SGA limit doesn't kick in immediately if you attempt to return to work. SSA offers a Trial Work Period (TWP) — nine months (not necessarily consecutive) within a rolling 60-month window — during which you can test your ability to work without losing benefits, regardless of how much you earn.
In 2025, a month counts as a Trial Work Period month if you earn more than $1,110 (a separate threshold SSA adjusts annually).
Once your nine Trial Work Period months are used up, SSA begins evaluating your earnings against the SGA threshold. A 36-month Extended Period of Eligibility (EPE) follows. During this window, any month you earn below SGA, you remain entitled to benefits. Any month you exceed SGA, your payment is withheld for that month.
If your earnings drop below SGA during the EPE, benefits can be reinstated without filing a new application. After the EPE ends, exceeding SGA will terminate your benefits, and reinstatement becomes a more involved process through Expedited Reinstatement (EXR).
SSA doesn't simply look at your pay stub. Several factors affect how earnings are counted:
Two SSDI recipients earning $1,650 a month could face completely different consequences depending on their circumstances:
Stage of benefits, nature of employment, documented work expenses, and whether self-employment is involved all shape how SGA analysis plays out for any given person.
SSA's Ticket to Work program allows SSDI recipients to access employment services and explore work without immediately triggering a review. Assigning your Ticket to an approved provider can also affect when and how SSA initiates continuing disability reviews — though it doesn't change the SGA threshold itself.
The 2025 SGA limit — $1,620 per month for most beneficiaries — is a fixed rule published by SSA. But whether crossing or staying under that line actually changes your benefit status depends on factors that vary person to person: how long you've been on SSDI, how many Trial Work Period months you've used, whether you're self-employed, and what deductible expenses apply to your situation.
The threshold is the same for everyone. What it means for any individual depends entirely on where they stand.
