Allowable Expenses That Can Reduce Your Countable Income Under SSDI Rules

If you're working while receiving SSDI benefits, you've probably heard that earning too much can put your benefits at risk. But the SSA doesn't simply count every dollar you earn — certain work-related costs can be subtracted from your gross earnings before the SSA measures them against the program's limits. Understanding how this works is one of the more practical — and underused — parts of the SSDI rules.

Why Earned Income Isn't Always What It Appears to Be

SSDI's primary income test is Substantial Gainful Activity (SGA). In 2024, the SGA threshold is $1,550 per month for non-blind recipients and $2,590 for those who are blind. These figures adjust annually.

If your gross monthly earnings exceed the SGA threshold, the SSA may determine you're no longer disabled under program rules. But gross pay isn't always the final number the SSA uses. Certain deductible expenses — called Impairment-Related Work Expenses (IRWEs) — can bring your countable earnings below SGA even if your paycheck looks higher on paper.

This is the mechanism most recipients don't know about, and it can make a real difference in whether your earnings count as SGA.

What Are Impairment-Related Work Expenses (IRWEs)?

IRWEs are out-of-pocket costs you pay for items or services that you need because of your disability — and that allow you to work. The SSA subtracts these costs from your gross earnings when calculating whether you've reached SGA.

To qualify as an IRWE, an expense generally must meet three conditions:

• It's directly related to your disabling impairment
• It's necessary for you to work (not just helpful in daily life)
• You pay for it out of pocket — it's not reimbursed by insurance, an employer, or another program
• It's a reasonable cost for the service or item

These aren't tax deductions — they're SSA accounting adjustments. You report them to the SSA, and the agency deducts them from your countable earnings before comparing that figure to SGA.

Common Examples of Allowable IRWE Expenses 🔍

The SSA has recognized a range of expenses across many disability types. Common examples include:

The list isn't exhaustive. The SSA reviews expenses on a case-by-case basis. What matters is the connection between the expense, your specific impairment, and your ability to work.

What IRWEs Do Not Cover

Not every medical expense qualifies. The SSA draws a line between expenses that enable work and those that are part of general living or medical maintenance.

Expenses that generally don't qualify as IRWEs:

• Costs you'd pay whether or not you worked (routine health insurance premiums in many cases)
• Expenses unrelated to your disabling impairment
• Costs reimbursed by Medicare, Medicaid, or a private insurer
• Items your employer provides or covers

The purpose test is strict: the expense has to connect your disability to your ability to perform work. If the item would be used regardless of employment, it typically doesn't qualify.

How IRWEs Interact With the Trial Work Period and EPE

IRWEs apply specifically to the SGA calculation — they're most relevant once you've completed your Trial Work Period (TWP) and entered the Extended Period of Eligibility (EPE), when SGA becomes the active test for continued benefits.

During the nine-month Trial Work Period, you can earn any amount without SGA triggering a cessation. Once the EPE begins, however, every month the SSA checks whether your earnings constitute SGA. That's when IRWEs become a practical tool — reducing countable income so that a working SSDI recipient who has real disability-related costs doesn't automatically lose benefits just because their gross paycheck crosses a threshold.

Subsidies and Special Conditions: Another Deduction Category

IRWEs aren't the only downward adjustment the SSA can make. Subsidies are another. If your employer is paying you more than the actual value of your work — because of extra supervision, reduced productivity, or special accommodations — the SSA may reduce your countable earnings to reflect your true contribution. This is separate from IRWEs but serves a similar function: aligning what you earn on paper with what the SSA considers your real work capacity.

How to Report IRWEs to the SSA ⚠️

IRWEs aren't automatic. You have to tell the SSA about them. Keep documentation: receipts, prescriptions, medical records connecting the expense to your impairment, and records of what you paid out of pocket. Report these expenses to your local Social Security office or work with a benefits counselor through programs like Ticket to Work, which offers free assistance navigating exactly these kinds of calculations.

The Variables That Shape Individual Outcomes

Whether specific expenses qualify — and how much they reduce your countable income — depends on factors no general article can fully resolve:

• The nature of your disability and how directly an expense relates to it
• Your type of work and whether the expense enables that specific job
• What's already covered by Medicare, Medicaid, or an employer
• How well you document the connection between expense, impairment, and employment
• Where you are in the SSDI timeline (TWP vs. EPE vs. initial benefit period)

Two recipients with similar conditions and similar jobs can have very different IRWE calculations depending on what they pay out of pocket and how thoroughly they've documented it. The rules are consistent — but what they produce for any given person isn't something the program's general framework can answer on its own.
