You put in the miles — client meetings, supply runs, coworking space visits — but the question of whether your employer has to pay you back for that driving can feel like a puzzle with missing pieces. Because here’s the thing that surprises most people: the IRS standard mileage rate for 2026 is 72.5 cents per business mile, but that number is a safe-harbor tax treatment under an accountable plan, not a federally mandated reimbursement floor. No federal law says your boss has to hand you a dime for those miles.

The Federal Hole Nobody Warned You About
It’s worth being honest about the gap here. The Fair Labor Standards Act only steps in if your unreimbursed expenses drop your net pay below the federal minimum wage of $7.25 per hour. That’s a very low floor. For salaried employees, the threshold is $684 per week. So unless you’re driving a truly staggering number of miles for work, the FLSA won’t help you.
The Department of Labor’s Field Operations Handbook clarifies that personal-vehicle expenses paid by employees can trigger minimum wage violations if net wages fall below that $7.25 line. But in practice, that’s a narrow exception — not a broad right to reimbursement.
Most people I talk to assume their employer is legally required to cover mileage. The gray area between what feels fair and what’s actually enforceable creates a lot of quiet resentment. Especially when you’re the one absorbing gas, wear and tear, and depreciation for tasks that directly benefit the company.
What about the Americans with Disabilities Act? It can require reimbursement for remote work expenses as a reasonable accommodation. But that’s a specific circumstance, not a blanket rule for every remote employee who drives for work.
If you’re in a state without its own reimbursement law, your leverage depends entirely on what your employment agreement says and whether your employer has a voluntary policy. Which brings us to the places that do have teeth.
State by State: Where the Rules Actually Exist
Ten jurisdictions impose an affirmative reimbursement duty: California, Illinois, Massachusetts, Montana, New Hampshire, North Dakota, South Dakota, Iowa, the District of Columbia, and the City of Seattle. If you live or work in one of these, you have real legal backing.
California’s Labor Code Section 2802 is the gold standard. It requires employers to reimburse all necessary expenditures incurred in direct consequence of discharging job duties. And the courts have been clear: remote work expenses like internet and phone bills are included. A 2023 case, Thai v. International Business Machines Corp., rejected the defense that stay-at-home orders caused the remote work — expenses incurred during performance of duties are reimbursable.
Illinois follows a similar path under the Illinois Wage Payment and Collection Act. Employees must submit requests within 30 days, but the law requires reimbursement for all necessary expenses that primarily benefit the employer.
Massachusetts takes a different approach. Its Wage Act allows treble damages for violations, and the Attorney General’s Office recommends reimbursing unavoidable and necessary expenses. That’s softer language than California’s statute, but the enforcement mechanism is tougher.
People assume their state’s general expense reimbursement law automatically covers mileage. But some states — like New York — only require reimbursement if there’s a written agreement or contract specifying it. Others, like Pennsylvania, let employees deduct unreimbursed expenses on their taxes rather than requiring employer payment. Know which category your state falls into before you assume you’re covered.
New York’s law is narrower than many realize. It applies only when an employer has agreed to provide reimbursement, and the law specifically excludes professionals earning over $1,300 per week. Pennsylvania’s approach is even more limited: employees can claim unreimbursed work expenses as deductions on their tax returns, but the employer doesn’t have to pay them directly.
Montana, North Dakota, and South Dakota share textually identical indemnification language to California’s code, carried from the same Field Code lineage. But enforcement varies. South Dakota’s law requires employers to cover all necessary expenses employees pay while doing their job or following employer orders. North Dakota excludes tools or equipment used outside the scope of employment.
Seattle stands alone among cities with its own reimbursement requirement. The Seattle Office of Labor Standards treats remote work-related business expenses as owed compensation.
The IRS Rate Is Not a Paycheck Guarantee
Here’s where the confusion runs deepest. The IRS mileage rate is a tool for tax purposes, not a wage law. When an employer uses an accountable plan — meaning expenses are business-related, substantiated within 60 days, and excess reimbursements returned within 120 days — the reimbursement is not taxable income. Under a nonaccountable plan, every dollar becomes taxable wages.
Reimbursing above the IRS rate without substantiation of actual costs makes the excess taxable wages under 26 CFR §1.62-2 and IRC §67(g). So if your employer pays you 75 cents per mile but doesn’t require receipts, that extra 2.5 cents is taxable income. The IRS standard mileage rate is a safe harbor, not a ceiling, but anything above it requires proof.
The One Big Beautiful Bill Act made the suspension of miscellaneous itemized deductions permanent under IRC §67(g). That means you can’t deduct unreimbursed employee business expenses on your federal taxes anymore. The tax deduction safety valve is gone. If your employer doesn’t reimburse you, you eat the full cost.
Some employers use FAVR plans — fixed and variable rate plans — as an alternative for large vehicle fleets. These combine a fixed monthly stipend with a variable per-mile rate. The IRS approved this structure under Rev. Proc. 2019-46, but it’s typically used by companies with many field employees, not individual remote workers asking for a few hundred miles of reimbursement.
Documentation: The Part That Makes or Breaks Your Claim
Even in states with strong reimbursement laws, you need proof. IRS regulations require contemporaneous logs for mileage claims — amount, time, place, and business purpose. Reconstructed logs receive less weight if a dispute arises.
26 CFR §1.274-5 is clear: you need a record made at or near the time of the expense. A spreadsheet you fill out quarterly won’t carry the same credibility as a mileage app that logs each trip automatically.
- Date and starting odometer reading
- Destination and business purpose of the trip
- Miles driven — app or manual log, just be consistent
- Ending odometer reading, if using a paper log
For employees in states without reimbursement laws, documentation serves a different purpose. It’s your evidence if you decide to negotiate a higher stipend or if you’re tracking expenses for a potential move to a state with stronger protections. It also matters if you’re claiming a state tax deduction in places like Washington, where unreimbursed expenses may still be deductible at the state level.
A few practical notes on the process. If your employer uses an accountable plan, you must submit documentation within 60 days and return any excess advance within 120 days. Miss those windows and the reimbursement becomes taxable income. That changes the math significantly — a $200 reimbursement at your marginal tax rate is worth less than $200.
When to Push Back and How to Do It
Lawsuits over remote work expenses are real. Amazon settled a California lawsuit in 2024 for nearly $1 million over unpaid home internet costs during COVID stay-at-home orders. Williams v. Amazon.com Services LLC resulted in a $950,000 settlement. Employees have also sued Wells Fargo, Liberty Mutual Insurance, Visa, Oracle, and Bank of America over unpaid remote work costs.
These cases typically settle because the law in California and Illinois is clear. But if you’re in a state without a reimbursement requirement, your leverage is different. You’re negotiating from a position of what the company wants to do to retain talent, not what it has to do.
Before you approach your employer, check your location’s legal status — the rules depend on where you’re physically working, not where the company is headquartered. If you live in a state with a reimbursement requirement but work for a company in a state without one, your state’s law typically applies.
Also worth understanding: the distinction between employee and independent contractor status matters here. Independent contractors can claim the home office deduction and business expense deductions that employees can’t. If you’re classified as an employee, those deductions are permanently off the table under IRC §67(g).
If your employer does have a voluntary reimbursement policy, make sure it’s written. A verbal promise about mileage reimbursement is hard to enforce. Written policies, even if voluntary, create a contractual expectation that some courts have upheld.
✦
Whether you’re owed mileage reimbursement depends on your state, not on the IRS rate or what feels fair. Look up your specific state law, start tracking your trips now, and check your employment agreement for any reimbursement language. If you’re in a state with a requirement, you have real leverage. If you’re not, you’re negotiating from goodwill — which means documentation and a clear ask matter even more.
