How Much Are You Allowed to Make on SSDI?

If you're receiving SSDI benefits — or applying for them — one of the most practical questions you'll face is how much you can earn from work without putting your benefits at risk. The answer isn't a single number. It depends on where you are in the SSDI process, whether you're in a trial period, and how the Social Security Administration (SSA) classifies your work activity.

Here's how the rules actually work.

The Core Concept: Substantial Gainful Activity (SGA)

SSDI is designed for people who can no longer work at a substantial level due to a disabling condition. The SSA measures "working at a substantial level" using a standard called Substantial Gainful Activity (SGA).

If your monthly earnings from work exceed the SGA threshold, the SSA generally considers you capable of substantial work — which can affect both your eligibility and your continued benefits.

The SGA limit adjusts annually. In 2025, the monthly SGA threshold is $1,620 for most applicants and $2,700 for people who are blind. These figures typically increase each year with cost-of-living adjustments (COLAs).

It's important to understand that SGA applies to earned income from work — not to investment income, rental income, or other unearned sources. SSDI is not means-tested the way SSI is, so passive income generally doesn't count toward SGA.

How SGA Works at Different Stages

The SGA limit doesn't operate the same way throughout your SSDI journey. Where you are in the process matters significantly.

During the Application Stage

When you apply for SSDI, the SSA checks whether you are currently engaging in SGA. If your earnings exceed the threshold at the time of your application, your claim can be denied at Step 1 of the five-step sequential evaluation — before your medical condition is even reviewed.

This is one of the earliest and most mechanical screens in the process.

After Approval: The Trial Work Period

Once approved, SSDI recipients aren't immediately cut off if they try to return to work. The SSA provides structured protections called work incentives.

The most important of these is the Trial Work Period (TWP). During the TWP:

• You can work and receive your full SSDI benefit regardless of how much you earn
• The TWP lasts for 9 months (not necessarily consecutive) within a rolling 60-month window
• In 2025, any month in which you earn more than $1,110 counts as a trial work month

The TWP is designed to let you test your ability to work without immediately losing benefits.

After the Trial Work Period: Extended Period of Eligibility

Once you've used your 9 trial work months, you enter the Extended Period of Eligibility (EPE), which lasts 36 months. During this window:

• If your earnings exceed SGA in any month, your benefits are suspended for that month
• If your earnings drop below SGA, your benefits can be reinstated without a new application
• After the EPE ends, earning above SGA generally results in termination of benefits

What Counts as "Earnings" for SGA Purposes?

The SSA doesn't always take your gross paycheck at face value. Several adjustments can affect how your income is counted:

• Impairment-Related Work Expenses (IRWEs): Costs directly related to your disability that allow you to work — such as medications, medical equipment, or certain transportation costs — can be deducted from your gross earnings before the SGA calculation
• Subsidies: If your employer is paying you more than the work you actually produce is worth (a common accommodation for disabled workers), the SSA may subtract the subsidy value
• Self-employment income is evaluated differently, with the SSA looking at net earnings and applying additional tests around hours worked and the value of services performed

These deductions can make a real difference for people whose gross income is near or slightly over the SGA line.

SSDI vs. SSI: A Critical Distinction 💡

SSDI and SSI are separate programs with different income rules. SSDI is based on your work history and payroll tax contributions. SSI is a needs-based program with strict income and asset limits that apply differently.

If you receive both (called dual eligibility or "concurrent benefits"), both sets of rules apply simultaneously — and the income calculation becomes more complex. SSI has its own earned income exclusions, and your SSDI payment counts as unearned income for SSI purposes.

Conflating the two programs is one of the most common sources of confusion around benefit limits.

The Ticket to Work Program

Recipients who want to explore work without jeopardizing their benefits can also enroll in the Ticket to Work program, a voluntary SSA initiative that provides access to employment services and additional protections against medical continuing disability reviews while participating.

It doesn't change the SGA thresholds, but it adds a layer of support and protection for people actively trying to re-enter the workforce.

Why the Right Number Depends on Your Situation 🔍

The SGA thresholds, trial work amounts, and EPE rules are uniform — but how they interact with your specific circumstances is not. The timing of your application, whether you're self-employed, the nature of your disability-related work expenses, and how your employer structures your compensation all shape what the SSA actually sees when it evaluates your earnings.

Someone earning $1,700 a month with significant impairment-related expenses may calculate well below SGA. Someone earning the same amount without those deductions may not. Two people at the same income level, at different stages of their SSDI timeline, face entirely different consequences.

The thresholds are public. How they apply to your work history, your condition, and your specific benefit status — that's the piece only your own situation can answer.
