Deductible Impairment-Related Work Expenses (IRWE)

An impairment-related work expense, called an IRWE, is a cost you pay out of pocket for an item or service that your impairment requires and that you need in order to work. When SSA decides whether your earnings show substantial gainful activity, it subtracts these expenses from your gross earnings first, under 20 CFR 404.1576(a).

The deduction can decide outcomes. In 2026, the substantial gainful activity level is $1,690 per month for nonblind beneficiaries and $2,830 for statutorily blind beneficiaries, per SSA's published figures. Take a 2026 example: gross pay of $1,800 with $250 of deductible expenses comes to $1,550 countable, which sits below the nonblind line of $1,690.

The Five Conditions Every IRWE Must Meet

Under 20 CFR 404.1576(b), SSA allows the deduction only when all of the following are true.

The severity of your impairment requires you to buy, rent, or pay for the item or service in order to work. You personally pay the cost. Another source has not paid it, and you have not been, could not be, or will not be reimbursed by insurance, Medicare, Medicaid, or any other plan, so a copay qualifies but a covered charge does not. You pay in a month you are working, and payment is in cash, a check, or another form of money rather than in kind.

Where the Deduction Is Used

SSA subtracts IRWEs whenever it decides whether work is substantial gainful activity: when you report work after entitlement, at work-triggered reviews, and month by month during the extended period of eligibility, since 20 CFR 404.1592a(a)(1) applies the full SGA rules of 20 CFR 404.1571 through 404.1576. The computation is the same in the SSDI and SSI programs under 404.1576(f)(4).

One exception deserves emphasis: the deduction does not apply when SSA decides whether a month was a trial work "services" month, per 404.1576(f)(2).

The deduction also survives inside the extended period of eligibility. Once SSA makes its first cessation finding during that period, the rules for unsuccessful work attempts and earnings averaging drop out under 20 CFR 404.1592a(a)(2)(i), but impairment-related work expenses do not, because the monthly substantial gainful activity test still runs through 20 CFR 404.1571 through 404.1576. Keeping receipts during those months matters as much as ever.

Attendant Care

Under 404.1576(c)(1), payments for attendant care are deductible. That includes help traveling to and from work, help at work with personal functions like eating or toileting, help with work functions like reading or communicating, and help at home getting ready for work and recovering from it, such as dressing or medication assistance.

Payments to a family member count only if that person suffered an economic loss by quitting or cutting back their own work to help. If an attendant splits time between helping you and doing general housework, only the part attributable to the qualifying services is deducted.

Medical Devices, Prosthetics, and Equipment

Durable medical equipment you need to work is deductible under 404.1576(c)(2), with the regulation listing wheelchairs, canes, crutches, inhalators, pacemakers, and hemodialysis equipment. Prosthetic devices, artificial arms, legs, and other replacement parts, are deductible under (c)(3).

Special work-related equipment counts under (c)(4)(i). The regulation's examples include one-hand typewriters, vision aids, sensory aids for the blind, telecommunication devices for the deaf, and tools specifically designed to accommodate an impairment. Installation, maintenance, and repair of any deductible item are also deductible under (c)(7).

Home and Vehicle Modifications

Residential modifications follow strict lines under 404.1576(c)(4)(ii). If you work away from home, only exterior changes that get you to your transportation count, such as an outside ramp, railings, or pathways. If you work at home, modifications to the interior workspace count, but a self-employed person cannot deduct the same cost as both a business expense and an IRWE.

For vehicles, under (c)(6)(iii)(A), the cost of structural or operational modifications required by your impairment is deductible, but not the vehicle itself, and a mileage allowance based on federal operating cost data is allowed for the trip to and from work.

Prescription Copays and Medical Services

Payments for drugs and medical services you need to control your impairment are deductible under 404.1576(c)(5). The regulation's own examples include anticonvulsant drugs and blood level monitoring for epilepsy, antidepressant medication, medication for treatment side effects, chemotherapy and radiation, corrective surgery for spinal disorders, and diagnostic tests such as electroencephalograms tied to a disabling condition.

Your copays and coinsurance fit naturally here, because they are the part you actually pay. Routine annual physicals, dental exams, and optician visits unrelated to a disabling visual impairment are not deductible.

Paratransit, Taxis, and Other Transportation

Transportation costs are deductible in defined situations under 404.1576(c)(6)(iii). If your impairment requires driver assistance, taxicabs, paratransit service, or other hired vehicles for you to work, the amounts you pay are deductible under (B). If your impairment prevents you from using available public transportation and you must drive your own unmodified car, a mileage allowance is deductible under (C), with the need verified by your physician or other sources. Combined with vehicle modifications under (A), these rules make commuting one of the most common IRWE categories.

Supplies, Service Animals, and Similar Items

Under 404.1576(c)(6), the category for similar items covers the purchase and maintenance of a dog guide you need to work, expendable medical supplies like catheters, bandages, incontinence pads, elastic stockings, and face masks, and physical therapy required because of your impairment. Nonmedical appliances such as air conditioners or air cleaners are generally not deductible, but (c)(4)(iii) allows them in unusual circumstances where a medically verified need makes the item essential to controlling your disabling condition at work.

Timing, Allocation, and Proof

The month you pay, not the month you incur the debt, controls the deduction under 404.1576(d). Recurring payments are deducted in each month paid under (e)(1). A one-time purchase can be deducted in full in the month paid or spread over 12 months, your choice, under (e)(2), and certain payments made during the 11 months before you started work can be allocated forward under (e)(4).

SSA deducts actual amounts unless they are unreasonable under (f)(1), using Medicare prevailing charges as a benchmark for medical items. Under (g), SSA will verify your need for the item, the charge, and your proof of payment, so keep receipts and prescriptions. A simple monthly log that matches each payment to a working month, as (d) requires, prevents most disputes before they start.

A Note for Blind Beneficiaries

The substantial gainful activity level is higher for people who are statutorily blind, at $2,830 per month in 2026 against $1,690 for others. SSA's Red Book describes additional differences in the way work and earnings are treated for blind beneficiaries, so if you are blind, read that section before tallying deductions. The core requirements of the IRWE rule itself, impairment-related, needed for work, paid by you, unreimbursed, are the same.

Frequently Asked Questions

Are costs I also have at home, like my medications, still deductible? Yes. Under 20 CFR 404.1576(a), an expense is deductible even though you also need or use the item for daily living, as long as your impairment requires it and you need it in order to work.

Can I deduct a big one-time purchase, like a wheelchair, all at once? Yes. Under 20 CFR 404.1576(e)(2), for a one-time payment you can deduct the entire amount in the month you pay it, or have SSA allocate it over 12 months starting that month, whichever you choose.

Does an IRWE stop a month from counting as a trial work month? No. Under 20 CFR 404.1576(f)(2), impairment-related work expenses are not deducted when SSA decides whether your work was services for trial work period purposes. The deduction matters for substantial gainful activity decisions.
