Start here: pick the question you have

MilitaryTaxBreak.com explains one federal deduction: the unreimbursed travel costs of National Guard and Reserve members who go more than 100 miles from home, overnight, for duty. Most visitors arrive with one of these six questions.

  • Which of my trips count? Drill weekends, annual training and schools are not all treated alike, and trips your orders already pay for are different again. Read which reserve trips count, then commute or deductible drill travel and the 100-mile rule.
  • What mileage rate do I use? The IRS business rate was 72.5 cents per mile from January 1, 2026 and 76 cents from July 1, 2026. The mileage rates by year page lists 2018 through 2026 with the IRS notice behind each one.
  • How much can I deduct for lodging and meals? The federal per diem rate for where you served is the ceiling, and meals are cut to 50 percent. See federal per diem rates and lodging and meals under the cap.
  • What records do I need? Estimates are not deductible, so you need a written log and receipts. Start with records to keep and the mileage log guide.
  • How does Form 2106 work now? Most employees can no longer use Form 2106, but Armed Forces reservists still can. The line-by-line Form 2106 guide shows how the amount reaches Schedule 1, line 12.
  • What about my state return? This is a federal deduction, and your state decides its own treatment of drill pay. Read state taxes and drill pay.

Featured guides

Each guide names its IRS or agency sources and works through an invented example with the arithmetic shown. The full list is on the all guides page.

Who qualifies for the reservist travel deduction

Checks the reserve-component, distance, travel and reimbursement tests one at a time, then applies them to four invented reservists so you can see where each one passes or fails.

Form 2106, line by line

Follows a reservist's receipts, miles and per diem limits through Form 2106 to Schedule 1, line 12, and explains why this deduction survived when most employee expenses did not.

A full drilling year, worked through

Uses made-up 2026 trips to show mileage at both 2026 rates, lodging held to the per diem cap, meals at 50 percent and a reimbursement subtracted, ending at the total that reaches Schedule 1.

How to keep a reservist mileage log

Lists what a usable log contains and shows how the July 2026 rate change splits the year, with a worked example. A log is what separates a deduction from an estimate.

Ten common mistakes

Covers frequent errors, such as mixing up rates or deducting costs that were reimbursed, states what the IRS wording requires instead, and puts dollar amounts on three of them.

Amending past returns

Explains how to file Form 1040-X if you missed the deduction in an earlier year, which years are still open for a refund claim, and how to rebuild drill records after the fact.

Reimbursed drill travel

Shows how accountable plans, allowances and W-2 code L change the deduction, and why it survived the suspension of employee expenses, with a worked year in four setups.

Combat zone tax exclusion

Explains how the exclusion differs for officers and enlisted members, which areas count, and how the earned income credit election works, with an invented example.

Also useful: short answers to common questions, the glossary, the drill pay calculator and military finance news.

Where the reservist figures come from

The travel rules on this page trace to the Internal Revenue Code, Publication 3 and Publication 463 and the Form 2106 instructions. Mileage rates come from IRS notices, lodging and meal limits from GSA per diem files, and drill pay from DFAS pay tables. We read the source document rather than a summary and link it where the rule appears. See the sources page for the full list and the editorial policy for how pages are reviewed.

How the reservist travel deduction works in brief

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, plus 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.

This is a federal deduction, so it is available to eligible Guard and Reserve members wherever they live or drill; how your own state treats drill pay and travel on a state return is a separate question, covered in our guide to state taxes and drill pay.
