How Much Are You Allowed to Make While on SSDI?

If you're receiving Social Security Disability Insurance — or hoping to — one of the most practical questions you can ask is how much income you're allowed to earn. The answer isn't a single number. It depends on how you earn it, what stage of SSDI you're in, and whether you're using any of SSA's built-in work incentives.

Here's how the rules actually work.

The Core Limit: Substantial Gainful Activity (SGA)

The Social Security Administration uses a threshold called Substantial Gainful Activity, or SGA, to determine whether someone is working "too much" to qualify for — or continue receiving — SSDI benefits.

If your earnings from work exceed the SGA limit, SSA generally considers you capable of supporting yourself and may deny or terminate your benefits.

For 2025, the SGA threshold is $1,620 per month for non-blind individuals, and $2,700 per month for individuals who are statutorily blind. These figures adjust annually, so they'll likely be different in future years.

A few important points about SGA:

• It applies to earned income — wages from a job or self-employment
• It does not apply to passive income like investment returns, rental income, or spousal earnings
• SSA can also look at the nature of your work, not just the dollar amount, when evaluating SGA

At the Application Stage vs. After Approval

The SGA threshold matters differently depending on where you are in the SSDI process.

Before approval: If you're applying and currently working above SGA, SSA will typically stop reviewing your application at step one of their five-step evaluation. Earning above SGA signals that you may not have a qualifying disability under their definition.

After approval: Once you're approved and receiving benefits, you don't lose them the moment you earn a dollar. SSA has work incentives specifically designed to let beneficiaries test their ability to return to work without immediately cutting off their checks.

The Trial Work Period: A Built-In Buffer 💼

One of the most important — and most misunderstood — SSDI work incentives is the Trial Work Period (TWP).

During the Trial Work Period, you can work and earn any amount without it affecting your SSDI benefits. SSA doesn't penalize you for earning over SGA during this time.

Here's how it works:

• You get 9 trial work months within any rolling 60-month window
• In 2025, a month counts as a trial work month if you earn more than $1,110
• The 9 months don't need to be consecutive
• Your benefits continue in full during all 9 months regardless of how much you earn

After you've used up your 9 trial work months, SSA enters a review period to determine whether your work exceeds SGA on a sustained basis.

The Extended Period of Eligibility (EPE)

After your Trial Work Period ends, you enter a 36-month window called the Extended Period of Eligibility (EPE).

During the EPE:

• Any month you earn below SGA, you receive your full SSDI benefit
• Any month you earn above SGA, your benefit is suspended — not permanently terminated
• If your earnings drop below SGA again within those 36 months, benefits can be reinstated without a new application

This structure gives beneficiaries a meaningful runway to test work without permanently gambling their benefits.

What Counts — and What Doesn't

Not all income is treated equally under SSDI rules.

SSA may also allow Impairment-Related Work Expenses (IRWEs) — costs you pay out-of-pocket related to your disability that allow you to work — to be deducted from your gross earnings when calculating SGA. This can meaningfully lower your countable income figure.

SSDI vs. SSI: A Critical Distinction

It's worth being clear: SSDI and SSI are different programs with different income rules.

SSDI is based on your work history and Social Security taxes paid. SSI is a need-based program with strict income and asset limits that apply to all income sources, not just wages.

If you receive both SSDI and SSI (known as dual eligibility), the income rules from both programs apply simultaneously — which makes the math more complicated.

This article covers SSDI income limits. SSI follows an entirely separate calculation.

The Variables That Shape Your Specific Situation 🔍

The SGA threshold and Trial Work Period rules apply to everyone on SSDI — but how they interact with your benefits depends on:

• When your Trial Work Period began and how many months you've used
• Whether you're self-employed, since SSA calculates SGA differently for self-employment (looking at hours worked and the value of your services, not just net profit)
• Whether you have IRWEs that reduce your countable earnings
• Whether you're in the EPE or beyond it
• Whether you're blind, which carries a higher SGA threshold

Someone who started working part-time last month faces a very different calculation than someone who used their full Trial Work Period three years ago and is now in their Extended Period of Eligibility. Same program rules — completely different picture.

That gap between the general rules and your specific timeline, earnings history, and benefit status is exactly what makes these questions harder to answer than they first appear.
