The One Big Beautiful Bill Act ended the federal mileage deduction for most W-2 employees. Employer reimbursement is the recovery path that's left — and it runs on the log you hand in. FuelMath builds that log for you, from a short description of the drive. No GPS.
If you get a W-2 and you drive your own vehicle for work, the rule you may remember from a few years ago no longer applies. Here's what changed and what it means for you.
OBBBA stands for the One Big Beautiful Bill Act, the 2025 tax law. For decades before it, employees could subtract unreimbursed work expenses — mileage included — on Schedule A, the part of the return where you itemize individual deductions instead of taking the standard flat amount. The 2017 Tax Cuts and Jobs Act paused that deduction through 2025. OBBBA made the change permanent for most employees. It's no longer a temporary pause with a return date on the calendar.
In plain terms: you can no longer subtract unpaid work miles from your federal return. What's left is the path that was always there and is now the only one that matters — employer mileage reimbursement. That path is very much open, and a clean mileage record is what unlocks it. W-2 mileage reimbursement now runs on documentation you hand in, not on anything you file in April.
Mileage reimbursement is money your employer pays you back for driving your own vehicle on company business. It's paid on top of your wages, not as part of them — which is why it usually arrives untaxed.
This trips people up, so it's worth being precise. Federal law does not force a private employer to reimburse mileage, and it does not set the rate when they do. What the IRS rate actually does is mark a ceiling: reimbursement paid at or below the standard business rate, under an accountable plan, is generally tax-free to you. Anything paid above that rate is generally treated as taxable wages.
That's why most employers land exactly on the IRS number — it's the most they can pay you without creating a tax problem for either side. The current standard business rate is 76 cents per mile, effective July 1, 2026. The IRS Mileage Rate 2026 guide carries the current figure and how it gets set.
The IRS publishes a separate standard rate for each kind of driving, and they aren't close to each other. Employer reimbursement runs on the business rate, so that's the number on this page. The other two matter if you also drive for medical reasons or for a charity, because those miles can still be deductible on a personal return even though your work miles no longer are.
Your employer may be glad to pay you back. They will almost always want documentation first — and they're generally allowed to require it. Four fields, every trip.
Plenty of employees used to drive casually and figure they'd sort it out at tax time. That safety net is gone. The log you hand your employer is the record now — if it's incomplete, so is your reimbursement.
Miles and dollars total up as you go — so you always know the number before you submit, instead of reconstructing it the night the report is due.
That running total is the point. Each trip you describe becomes a dated line item underneath it — origin, destination, purpose, miles, and the dollar value at the current IRS rate — and the whole cycle exports as a single PDF, CSV, or email your employer can approve without asking you a single follow-up question.
Most mileage tools ask you to grant location access, tap start, drive, tap stop, and classify the trip afterward. FuelMath skips all of it — you say what you did, in ordinary words, and the log entry is built for you.
The OBBBA change lands hardest on people whose work happens at other people's addresses — and who don't already have a reimbursement process in place. If your role is on this list, employee mileage reimbursement is worth asking about.
Even with no federal write-off, several states require employers to cover reasonable business expenses — mileage included. Where you work may matter more than you think.
You have fewer options than you did before 2025, but not zero. Check your state's law first. Negotiate a policy — a documented record of what you actually drive gives you a concrete place to start that conversation. Ask about a car allowance or fleet vehicle, keeping in mind a flat allowance is often taxable income. Factor it into your pay — if reimbursement isn't coming, the yearly dollar value of your unpaid miles is real compensation data for a salary review. And keep the log either way: if the policy changes, or you move to a job that does reimburse, you'll already have the habit and the record.
