What the One Big Beautiful Bill Changed About Mileage Deductions

The 2025 One Big Beautiful Bill made one quiet but important change to mileage deductions: the W-2 mileage deduction is now permanently gone. If you are a self-employed driver, nothing changed for you. If you are a W-2 employee who used to deduct mileage on Schedule A, the door has now closed for good.

The Backstory

Before 2018, W-2 employees could deduct unreimbursed business expenses, including mileage, on Schedule A as a miscellaneous itemized deduction. The deduction was already narrow: it was only available to people who itemized, and only the portion above 2 percent of adjusted gross income could be claimed.

The Tax Cuts and Jobs Act of 2017 suspended this deduction for tax years 2018 through 2025. The suspension was scheduled to expire at the end of 2025, with the deduction returning in 2026.

The One Big Beautiful Bill, signed in 2025, made that suspension permanent. There is no longer a sunset date. W-2 employees cannot deduct unreimbursed mileage on the federal return for 2026 or any future year.

Who Is Affected

Anyone who receives a W-2 and drives their personal vehicle for work without full reimbursement from their employer. This includes:

• Nurses and home health aides who drive between patient homes
• Teachers who drive between schools or to required off-site events
• Social workers who travel to client homes
• Field service technicians who drive between job sites
• Construction trades classified as W-2 employees rather than 1099 contractors
• Sales representatives on a W-2 with mileage that exceeds employer reimbursement
• Hospitality staff required to travel between locations on shift

Who Is NOT Affected

Three groups are unchanged:

• Self-employed workers and 1099 contractors. The mileage deduction on Schedule C, line 9 was never affected by TCJA or OBBBA. Self-employed filers continue to deduct at 72.5 cents per mile in 2026.
• Members of the Armed Forces reserves traveling more than 100 miles from home. An above-the-line carve-out preserved by both TCJA and OBBBA.
• Qualified performing artists and fee-basis state or local government officials. Narrow above-the-line carve-outs that survived both bills.

For everyone else with a W-2, the federal mileage deduction is gone.

What Your Remaining Options Are

If you are a W-2 employee who drives for work, you have three options:

1. Get reimbursed by your employer

In nine states, your employer is legally required to reimburse you. California (Labor Code §2802), Illinois (820 ILCS 115/9.5), Massachusetts, New York (in limited cases), Washington (Seattle and beyond), New Hampshire (RSA 275:57), North Dakota, Montana, and Iowa all have mileage reimbursement laws on the books. See the breakdown by state.

In the other 41 states, employer reimbursement is voluntary, but most large employers offer it as a matter of policy. If yours does not, ask. The IRS rate of 72.5 cents per mile is what most employers use as a benchmark.

2. Switch to a 1099 arrangement (if it makes sense)

For some workers, especially in trades and field services, switching from a W-2 to a 1099 contractor relationship makes the mileage deduction available again, plus a long list of other business deductions. This is a major change with implications for benefits, taxes, and worker protections, and it is not always possible. Talk to a tax professional before pursuing this.

3. Track your miles anyway

Even without a federal deduction, a clean mileage log is the document that lets you collect reimbursement from your employer if you are owed it. In states with mandate laws, employees who tracked miles win wage claims. Employees who did not, settle for less or get nothing. The log is the leverage.

What State Tax Returns Look Like

A few states allow unreimbursed employee expenses on the state return even though federal law disallows them. The list is small and worth checking specifically for your state, because most states conform to the federal rules: California, Hawaii, Pennsylvania, Minnesota, and a few others have partial exceptions. Most states do not.

For self-employed filers, the federal mileage deduction flows through to the state return automatically in states that use federal AGI as the starting point for state tax. See your state's details.

The Bottom Line

OBBBA did not invent the W-2 mileage problem. TCJA created it in 2018. OBBBA just made permanent what was supposed to be temporary. If you have been working as a W-2 employee since 2018, the only thing that changed for you is that the deduction you have not been able to claim for the last seven years is no longer scheduled to come back. Plan accordingly.

If you are self-employed, this changes nothing about your filing. Your Schedule C, line 9 deduction is unaffected.
