Will You Lose Your SSDI If You Work Part-Time?

Working part-time while receiving SSDI doesn't automatically end your benefits — but it can, depending on how much you earn and when. The Social Security Administration has specific rules that govern what happens when beneficiaries work, and understanding those rules is what separates a safe return to work from an unintended loss of benefits.

The Core Rule: Substantial Gainful Activity (SGA)

The SSA measures work activity using a threshold called Substantial Gainful Activity (SGA). If your earnings exceed the SGA limit in a given month, the SSA may determine you're no longer disabled under their definition — regardless of your medical condition.

The SGA threshold adjusts annually. In 2025, the limit is $1,620 per month for non-blind individuals and $2,700 per month for those who are statutorily blind. If your part-time earnings stay consistently below those figures, your benefits generally aren't at immediate risk based on income alone. But crossing that threshold — even briefly — triggers a review process with real consequences.

The Trial Work Period: A Built-In Buffer 🛡️

For people already receiving SSDI, the SSA provides a Trial Work Period (TWP) — one of the program's most important work incentives. During the TWP, you can test your ability to work for up to 9 months (not necessarily consecutive) within a rolling 60-month window without losing your benefits, regardless of how much you earn.

In 2025, any month in which you earn more than $1,110 counts as a trial work month. Once you've used all 9 trial work months, the SSA looks at your earnings more closely.

After the TWP ends, you enter the Extended Period of Eligibility (EPE) — a 36-month window during which your benefits can be reinstated quickly in any month your earnings fall below SGA, without having to file a new application. That safety net matters significantly for people whose work capacity fluctuates due to their condition.

What "Part-Time" Actually Looks Like Under SSA Rules

The SSA doesn't use the term "part-time" — it uses earnings and work activity as its measuring stick. A part-time job paying $800/month looks very different from one paying $1,700/month:

These thresholds adjust annually and the interaction between them is precise — which is why tracking your monthly earnings carefully matters.

The Ticket to Work Program

The SSA also offers the Ticket to Work program, available to SSDI recipients between ages 18 and 64. Participating in Ticket to Work can provide access to employment services and, importantly, may protect you from certain Continuing Disability Reviews (CDRs) while you're working toward self-sufficiency. It doesn't suspend the SGA rules, but it's designed to support beneficiaries who want to explore work without immediately jeopardizing their status.

When the Risk Is Highest ⚠️

The stakes change depending on where you are in the SSDI process:

Still applying or waiting on a decision? Working above SGA during the application period is one of the fastest ways to get denied. The SSA uses SGA as an initial gatekeeping test — if you're earning above the threshold when they evaluate your claim, you may not clear that hurdle at all, regardless of your medical condition.

Recently approved? You're likely in or approaching your Trial Work Period. This is the window where part-time work is most protected — but it's finite.

Years into receiving benefits? You've likely used your TWP already, or it may be partially used. At this stage, earnings above SGA in any month can directly trigger a suspension of payments.

Impairment-related work expenses are one factor that can reduce your countable income for SGA purposes. If you pay out of pocket for items or services — medication, transportation, equipment — that are directly tied to your disability and necessary for you to work, the SSA may deduct those costs from your gross earnings before comparing them to the SGA threshold.

What a Continuing Disability Review Could Mean

When you work, especially above certain thresholds, you may prompt the SSA to conduct a Continuing Disability Review — a periodic check on whether you still meet the definition of disability. CDRs happen on a scheduled basis regardless of work activity, but work can accelerate or trigger them. If your medical condition has improved significantly and you're now working, a CDR could result in a termination of benefits on medical grounds — separate from the earnings question entirely.

The Variables That Shape Your Specific Risk

Whether part-time work puts your SSDI at risk depends on a tangle of overlapping factors:

• How much you're earning relative to the current SGA threshold
• How many trial work months you've used and when
• Whether you have impairment-related work expenses that reduce countable earnings
• The nature of your disability and whether it's subject to medical improvement
• Whether you're in the application phase or already receiving benefits
• Whether you're participating in Ticket to Work

Someone earning $900/month with no TWP months used is in a very different position than someone earning $1,500/month who exhausted their trial work period two years ago — even if both would describe themselves as "working part-time."

The program has more flexibility built into it than most people expect. It also has more precision. How that precision applies to your situation depends entirely on your own numbers, history, and timing.
