Yes — but within specific limits that Social Security sets and monitors. SSDI does not require you to stop working entirely, but it does require that your earnings stay below certain thresholds, and it tracks how work activity affects your eligibility over time. Understanding where those lines are drawn is the starting point for any SSDI recipient thinking about earning income.
SSDI is not a needs-based program the way SSI is. Your benefit amount is calculated from your earnings history, not your current income. But Social Security does care whether you're working — specifically, whether your work rises to the level of Substantial Gainful Activity (SGA).
SGA is the monthly earnings benchmark SSA uses to define "substantial" work. If you earn above the SGA threshold, SSA generally considers you capable of substantial work — which can affect your eligibility. The SGA amount adjusts annually. In 2024, it sits at $1,550 per month for most recipients, and $2,590 per month for individuals who are blind. Those figures change each year with cost-of-living adjustments, so always verify the current threshold at SSA.gov.
Earning below SGA doesn't automatically guarantee your benefits continue — your medical condition and other factors still apply — but crossing above SGA is a clear trigger SSA uses to evaluate your case.
One of the most important and underused provisions in SSDI is the Trial Work Period (TWP). SSA designed it specifically to let recipients test their ability to work without immediately losing benefits.
During the TWP, you can earn any amount for up to nine months (not necessarily consecutive, within a rolling 60-month window) while still receiving your full SSDI payment. In 2024, a month counts as a trial work month when you earn $1,110 or more.
After you use all nine trial work months, SSA evaluates whether your earnings exceed SGA. If they do, your benefits can stop. If they don't, benefits generally continue.
Once the TWP ends, you enter the Extended Period of Eligibility (EPE) — a 36-month window during which SSA evaluates your earnings month by month. If you dip below SGA during the EPE, benefits can be reinstated relatively quickly without filing a new application. This is a meaningful safety net for people whose work is inconsistent or interrupted by their condition.
After the EPE ends, the rules tighten. If you go back to earning above SGA at that point, reinstating benefits typically requires a new application process — though Expedited Reinstatement (EXR) may be available within five years of your benefits stopping.
SSA offers a voluntary program called Ticket to Work for SSDI recipients between ages 18 and 64 who want to return to work. Participating can provide access to employment services, vocational rehabilitation, and — importantly — protection from certain medical reviews while you're working toward financial independence.
Participation is entirely optional, and outcomes vary based on individual circumstances.
Not all income is treated the same way under SSDI:
| Income Type | Counted Against SGA? | Notes |
|---|---|---|
| Wages from employment | ✅ Yes | Primary measure SSA uses |
| Self-employment income | ✅ Yes | Calculated differently; SSA looks at net earnings and hours worked |
| Investment/passive income | ❌ No | Dividends, rental income, interest not counted |
| Gifts or inheritance | ❌ No | Not earned income for SSDI purposes |
| SSI payments | N/A | Separate program with its own income rules |
This is a meaningful distinction. Someone receiving dividends from investments is in a very different position than someone earning wages at a part-time job — even if the dollar amounts look similar.
If you work and have disability-related costs tied to that work — specialized transportation, equipment, medications — SSA may allow you to deduct those costs from your gross earnings when calculating whether you've exceeded SGA. These are called Impairment-Related Work Expenses (IRWEs).
This provision can meaningfully shift where your earnings land relative to the SGA threshold. The rules around what qualifies are specific, and SSA must approve each expense.
Whether working affects your benefits depends on factors that vary from person to person:
Someone with a stable physical condition who can work part-time and keep earnings just below SGA is in a fundamentally different situation than someone whose condition causes unpredictable flare-ups, or someone who just completed their ninth trial work month.
The rules around earning money on SSDI are more flexible than most people assume — but they're also layered in ways that depend almost entirely on where you stand in the process and what your individual work and medical history looks like.
