Quick Fact: Come 2026, the IRS will let employees deduct unreimbursed work-related travel expenses—but only if they itemize and jump through the usual hoops. For 2025 tax filings, the standard mileage rate for business travel jumps to 67 cents per mile, up from 65.5 cents in 2024. IRS
What are the IRS rules on employee travel expenses?
The IRS splits travel costs into two piles: reimbursed and unreimbursed, and the rules aren’t the same for W-2 employees versus 1099 contractors.
Employees who pay their own way for job-related travel can deduct it only if the company never reimburses them and the trip fits the IRS definition of a “business trip.” Contractors, on the other hand, can write off travel costs regardless of reimbursement, but they report the reimbursements as income.

Which trips actually count as business travel?
A deductible business trip has to take you away from your “tax home” for longer than a normal workday and require rest or sleep.
Overnight stays qualify. So do trips that last more than a year when you keep a regular place of business elsewhere. Your daily commute to the office? Not a chance. IRS Publication 463
What travel costs can I write off?
- Transportation: Airfare, train, bus, or 67 cents per mile in 2025 if you drive your own car.
- Lodging: Hotels or any place you crash overnight while you’re on the road.
- Meals: Half of what you spend on meals while traveling, but save receipts when a single meal tops $75.
- Incidentals: Tips, laundry, baggage fees, and those business calls you make from the hotel lobby.
How do accountable and non-accountable reimbursement plans differ?
Accountable plans let employers reimburse you tax-free; non-accountable plans hand you taxable wages instead.
Employers basically pick one of two IRS-approved routes:
| Plan Type | Tax Treatment | Recordkeeping Requirement |
|---|---|---|
| Accountable Plan | Reimbursements never show up on your W-2; no income or payroll tax gets withheld | You’ve got 60 days to turn in receipts and the business purpose of the trip |
| Non-Accountable Plan | Every dollar the company sends you gets taxed as regular wages | No receipts or business purpose needed |
What mistakes do employees make when claiming travel deductions?
Two big ones: trying to deduct daily commutes and meals eaten while working late at the office.
Neither flies with the IRS. Also, unreimbursed expenses only help if you itemize and your total deductions clear the standard-deduction bar—$14,600 for single filers and $29,200 for married couples filing jointly in 2025. IRS Standard Deduction
Which workers still get full write-offs?
Some professions dodge the IRS limitations:
- Union members: Dues and unreimbursed job-related costs still count.
- Long-haul drivers: Mileage and lodging for over-the-road gigs qualify.
- Sales pros: Travel between client sites—not home to office—can be deductible.
Do state laws change what employers must reimburse?
Yep—state labor codes can force reimbursement even when federal tax rules stay silent.
A few examples:
- California: Employers must cover “all necessary expenditures or losses incurred by the employee” for job-related travel. California Labor Commissioner
- Illinois: Reimbursement is required for all “reasonable and necessary” expenses, including mileage at the IRS rate. Illinois Department of Labor
- Pennsylvania: No state mandate, but companies using accountable plans still grab the tax perks. Pennsylvania DLI
