How the reservist travel deduction works

Members of a reserve component of the Armed Forces (Army/Air/Navy/Marine/Coast Guard Reserve, the National Guard, and the Reserve Corps of the Public Health Service) can deduct unreimbursed travel expenses for reserve duties performed more than 100 miles from home. Unlike most employee business expenses — which the 2017 tax law suspended — this one survived and remains an above-the-line adjustment, meaning you claim it whether or not you itemize.

Do I qualify?

You generally qualify if you are a member of a reserve component, you traveled more than 100 miles away from your home to perform your reserve duties, you were away from home overnight, and your employer/unit did not reimburse those expenses. If you were reimbursed, you can't also deduct that portion.

What can I deduct — and what are the limits?

Your deduction is capped at the federal per diem rate for your duty location (lodging + meals & incidental expenses, from GSA.gov) for lodging and meals, plus the standard mileage rate for driving your own vehicle, plus any parking fees, tolls, and ferry fees. Meals are subject to the 50% limit. The 2026 standard mileage rate is 76¢/mile (it was 72.5¢ before July 1, 2026); 2025 was 70¢/mile.

Which forms do I file?

Calculate the expenses on Form 2106 (Employee Business Expenses), then carry the reserve-related amount to Schedule 1 (Form 1040), line 12. It reduces your adjusted gross income directly.

How do I prove it?

Keep your drill/orders showing dates and location, a mileage log (dates, destinations, miles), and lodging receipts. Good records are what protect the deduction if the IRS ever asks.
