Impairment-Related Work Expenses and Your SGA Count

Impairment-related work expenses allow disabled workers to subtract the out-of-pocket costs of specialized items and services they need in order to work from their gross monthly wages. In 2026, when the substantial gainful activity limit is $1,690 for non-blind claimants and $2,830 for statutorily blind workers, deducting these costs can reduce countable income below the threshold and prevent a technical denial at Step 1.

The Social Security Administration (SSA) evaluates current work activity under 20 CFR 404.1520(b). If an applicant's earnings exceed the monthly substantial gainful activity (SGA) threshold, SSA denies the application immediately without reviewing medical records. However, under 20 CFR 404.1574(b)(1), the agency does not measure raw paychecks. Instead, it subtracts approved impairment-related work expenses (IRWE) to calculate your true countable earnings.

How IRWE Deductions Function at Step 1

Step 1 of SSA's five-step sequential evaluation process asks whether an applicant is working at the SGA level. Substantial work involves significant physical or mental duties, while gainful work is performed for pay or profit, as established in 20 CFR 404.1572.

For employees, gross earnings serve as the baseline starting point under 20 CFR 404.1574(a). When an applicant's gross wages hover near or slightly above the monthly cap, allowable deductions become critical. Under 20 CFR 404.1576, the reasonable costs of certain items and services are subtracted from gross earnings.

Consider an example for 2026. A non-blind claimant works part-time in 2026 and receives gross wages of $1,900 per month. On paper, those wages exceed the 2026 non-blind SGA limit of $1,690 per month. But the worker pays $350 each month out of pocket in 2026 for specialized medications and paratransit fares needed to commute with a severe spinal condition.

In 2026, SSA subtracts the $350 IRWE from the $1,900 gross pay. The worker's countable earnings become $1,550 per month for 2026. Because $1,550 is below the 2026 limit of $1,690, the applicant successfully clears Step 1, allowing the claim to proceed to medical review.

The Five Mandatory Criteria for an IRWE

Not every medical bill or work-related cost qualifies for this deduction. Under 20 CFR 404.1576(a) and Social Security Ruling (SSR) 84-26, an expense must satisfy five distinct legal requirements to count as an IRWE:

1. The Item or Service Must Enable You to Work

The expense must have a direct connection to your ability to obtain, perform, or retain your employment. If you could perform your job duties without the item or service, the cost cannot be deducted as an IRWE under 20 CFR 404.1576(a)(1).

2. You Must Need It Because of a Severe Impairment

The item or service must be medically necessary due to a severe physical or mental impairment verified by medical evidence. Routine expenses that healthy workers incur, such as standard business suits or basic commuting costs, do not qualify under SSR 84-26.

3. You Must Pay the Cost Out of Pocket

Under 20 CFR 404.1576(a)(3), you must pay for the expense yourself. If the cost is covered or reimbursed by private health insurance, Medicare, Medicaid, a vocational rehabilitation agency, or an employer, it cannot be claimed as an IRWE. Only unpaid deductibles, copayments, or entirely uncovered medical costs qualify.

4. Payment Must Occur in a Month You Work

Under 20 CFR 404.1576(a)(4), you must make the payment in a month during which you performed work activity. Certain exceptions exist under POMS DI 10520.025 for durable medical equipment purchased in the month immediately preceding your return to work.

5. The Expense Must Be Reasonable

Under 20 CFR 404.1576(a)(5), the amount paid must represent the prevailing cost for that item or service in your geographic community. Adjudicators can reduce the deduction if an expense substantially exceeds local market rates.

Qualifying Categories of Impairment-Related Work Expenses

The Social Security Administration categorizes allowable IRWE items in its Program Operations Manual System (POMS) under DI 10520.010. The most common categories include the following items.

Prescription Medications and Medical Treatments

Many individuals with chronic conditions require regular therapies to control symptoms well enough to work. Out-of-pocket costs for prescription drugs, chemotherapy copays, dialysis sessions, physical therapy, and mental health counseling qualify as IRWE deductions under 20 CFR 404.1576(c)(5).

For instance, a worker with epilepsy who pays $200 each month out of pocket in 2026 for anticonvulsant medications can deduct that amount, provided the medication controls seizures sufficiently to permit work.

Durable Medical Equipment and Assistive Devices

Under 20 CFR 404.1576(c)(1), payments for medical devices and equipment that you require to function at work qualify as deductions. Common examples include manual or motorized wheelchairs, mobility scooters, orthotic braces, artificial limbs, crutches, oxygen concentrators, specialized computer monitors, and screen-magnification software.

Attendant Care Services

Under 20 CFR 404.1576(c)(2), fees paid to an attendant who assists you with personal needs qualify as an IRWE if the assistance enables you to travel to work, perform job duties, or return home.

Qualifying attendant care includes assistance with dressing, bathing, preparing medical equipment, transferring to a wheelchair, or administering medications prior to the workday. It also includes personal assistance provided at the work site, such as taking notes or navigating workplace facilities.

SSA does not allow deductions for services an attendant provides to other family members, such as childcare or general household cleaning. Furthermore, payments made to a relative generally do not qualify unless the relative suffered a verifiable loss of other income to provide the attendant services under POMS DI 10520.010.

Specialized Transportation Costs

Standard travel between home and work is a normal personal expense that cannot be deducted. However, under 20 CFR 404.1576(c)(6), transportation costs become deductible when your impairment creates special travel requirements:

• Structural modifications to a private motor vehicle, such as hand controls, wheelchair lifts, or lowered floors.
• The cost of hiring a driver or paying for paratransit services when your impairment prevents you from operating a standard vehicle or using available public transit.
• Mileage allowances calculated by SSA for operating a modified vehicle, but only for travel directly related to commuting to work.

If you purchase an adapted vehicle, only the cost of the structural modifications qualifies as an IRWE, not the base purchase price of the standard vehicle itself under POMS DI 10520.010.

Service Animals

Claimants who rely on trained service animals to work can deduct out-of-pocket expenses under 20 CFR 404.1576(c)(3). Qualifying costs include the purchase price of the animal, training classes, food, veterinary visits, licenses, and necessary gear. The animal must be trained to perform specific tasks that assist with the worker's disabling condition.

Calculating Recurring Versus Lump-Sum Expenses

The administrative accounting method for IRWE depends on whether the cost is an ongoing monthly bill or a single large purchase. POMS DI 10520.025 outlines the rules for allocating costs:

For recurring monthly expenses, such as monthly prescription copayments or attendant care salaries, SSA deducts the actual amount paid in each respective month.

For large one-time purchases, such as spending $3,600 on a motorized wheelchair in 2026, deducting the entire amount in a single month would wipe out earnings for that month but provide no relief in subsequent months. Therefore, under POMS DI 10520.025, SSA allows the applicant to allocate the lump-sum cost evenly over a period of up to 12 consecutive months in 2026.

Verifying Expenses With Social Security

The burden of proving impairment-related work expenses rests entirely on the applicant. Adjudicators will not apply deductions based on rough estimates or unsupported verbal statements.

To claim an IRWE, claimants must report their work activity on Form SSA-821-BK (Work Activity Report - Employee). This form provides dedicated sections to list every expense, its medical necessity, and the monthly dollar amount paid.

Adjudicators require concrete verification, including cancelled checks, bank statements, pharmacy receipts, and a written statement from an acceptable medical source explaining why the device, medication, or service is necessary. Under POMS DI 10520.030, adjudicators also verify whether any third party reimbursed the cost.

Eligibility Scope and Administrative Boundaries

Understanding IRWE rules is essential for protecting your eligibility at Step 1 of the disability process. However, clearing Step 1 is only the first hurdle. Once your countable earnings fall below the 2026 SGA threshold, you must still establish that your medical condition meets a Blue Book listing or prevents you from performing past work and other jobs under Step 4 and Step 5.

Furthermore, post-entitlement work rules, such as the trial work period under 20 CFR 404.1592, follow different operational mechanisms and apply only after benefits are formally awarded. The procedural steps for filing an initial claim or submitting an administrative appeal are covered on sibling sites. Claimants seeking initial eligibility should concentrate on collecting receipts and medical statements that verify their out-of-pocket work costs.

Frequently Asked Questions

What is an impairment-related work expense for SSDI? Under 20 CFR 404.1576, an impairment-related work expense is an out-of-pocket cost for an item or service that you need because of a severe physical or mental condition in order to work, which SSA subtracts from gross pay before testing for substantial gainful activity.

Does health insurance reimbursement disqualify an expense as an IRWE? Yes. Under SSA regulations, you can only deduct costs that you pay directly from your own pocket without reimbursement from private health insurance, Medicare, Medicaid, or any other third party.

Can a one-time medical expense be deducted across multiple months? Yes. Under POMS DI 10520.025, SSA permits claimants who make a large lump-sum purchase for an essential work-related item to prorate that expense over a period of up to 12 consecutive months.
