You drive to a client site, a supply run, an offsite meeting — and somewhere in the back of your mind you wonder: is this miles I should be tracking? The answer is tangled in a mix of state laws, IRS rules, and a fundamental question about where your “office” actually lives. When your home is your primary work location, travel from your door to another business stop can shift from a nondeductible commute to a reimbursable business trip — but only if the rules line up in your favor.
Employee Rights Mileage Reimbursement Legal Landscape
Heads up — this post may include links to things I use or like, and I might earn a little something if you shop through them. Doesn’t cost you anything extra, and I only mention stuff I’d actually recommend.
When a Drive Stops Being a Commute
The IRS has long held that travel between your home and your regular place of work is a nondeductible commute. But when your regular place of work is your home — because your employer closed the office or you’re fully remote — that definition cracks. According to a guide on mileage reimbursement for home-based employees, when the office is closed and the employee works from home, the home can be considered the office location, meaning distance from home to another business location is no longer a commute (CompanyMileage analysis). That shift matters because it opens the door to reimbursement for trips that would otherwise fall under personal commuting.
But here’s where it gets practical: your employer has to agree that your home qualifies as your principal place of business. That’s not automatic. Some employers still treat any departure from home as personal travel, especially if you have a hybrid arrangement. The distinction often hinges on whether you regularly perform a significant portion of your work at home and whether your employer requires you to be there rather than at a company office.
I hear from remote workers who drive to a client visit or a team lunch and get told “that’s your commute.” They know it doesn’t feel right — they’re doing business — but without a clear policy, they’re stuck eating the cost. You shouldn’t have to guess whether a trip counts. A written mileage policy that explicitly names home as a work location takes the guesswork out.
The Federal Floor: What the FLSA Actually Says
There is no federal law that says your employer must reimburse you for mileage when you work from home. The Fair Labor Standards Act only steps in if your unreimbursed expenses push your effective hourly wage below the federal minimum — currently $7.25 an hour (U.S. government minimum wage page). That’s a low bar. For most salaried or higher-paid hourly workers, the FLSA provides no real protection on mileage reimbursement.
The Department of Labor’s “free and clear” rule under 29 CFR §531.35 says wages must be paid unconditionally, and any expense that cuts into minimum wage or overtime is a violation. In practice, that means if you earn $30 an hour and drive 50 business miles in a week, the cost of those miles — roughly $36 at the 2025 IRS rate — doesn’t bring your pay below minimum wage, so the FLSA doesn’t force reimbursement. The federal framework is essentially a safety net for low-wage workers only.
A lot of remote workers assume their employer is legally required to reimburse every business mile. That’s true in a handful of states, but at the federal level it’s only a requirement when the expense cuts into minimum wage. If you’re earning above that threshold and live in a state without its own reimbursement law, your employer may reimburse voluntarily — but they don’t have to. Always check your state law before assuming you’re owed something.
State Laws That Change Everything
For remote workers in certain states, the picture looks very different. Currently, ten jurisdictions impose an affirmative duty on employers to reimburse necessary business expenses, including mileage: California, Illinois, Massachusetts, Montana, New Hampshire, North Dakota, South Dakota, Iowa, the District of Columbia, and the city of Seattle (ClockSpot research on state requirements).
California’s Labor Code §2802 is the broadest. It requires employers to indemnify employees for “all necessary expenditures or losses incurred in direct consequence of the discharge of his or her duties.” That includes mileage for business travel from home. California courts have made clear that this obligation applies even when the expense was incurred because of a government stay-home order (Thai v. International Business Machines Corp., 2023). Illinois and Montana have nearly identical language. Massachusetts goes a step further — enforcement through the Wage Act can bring treble damages for unpaid reimbursements.
If you live in one of these states, you have a legal right to be reimbursed for business miles driven from your home. If you don’t, your leverage depends on your employer’s policy or your ability to negotiate. That’s a wide gap, and it’s worth knowing which side you’re on.
Building a Paper Trail That Holds Up
Whether reimbursement is mandatory or discretionary, the documentation you provide determines whether you actually get paid. The IRS requires a mileage log that records, for each trip: the number of business miles, the date and destination, and the business purpose (26 CFR §1.274-5). A contemporaneous log — made at or near the time of the trip — carries the most weight. Reconstructed logs are allowed but invite pushback if your employer or the IRS ever questions them.
For remote workers, the key is to distinguish clearly between personal errands and business travel. A trip to the post office to mail a client contract is business. A trip to pick up groceries on the way home from a meeting is personal — you can only claim the portion that’s directly business-related. If your employer reimburses at the IRS standard mileage rate, they’ll expect you to substantiate every mile.
- Choose a method you’ll actually use. A spreadsheet, a mileage app, or even a notebook in the car. The best system is the one you stick with.
- Log trips immediately after they happen. Waiting until the end of the month invites forgotten stops and fuzzy purposes.
- Include the business purpose in enough detail. “Client meeting” is fine; “drove to ABC Corp to discuss Q3 deliverables” is better.
- Submit claims on a regular schedule. Many employers require expense reports within 60 days. If you wait too long, you risk losing reimbursement under an accountable plan.
If you’re unsure whether your employer will reimburse a particular trip, ask before you drive. A simple email — “I need to drive to the client site for a meeting tomorrow — can you confirm whether mileage is reimbursable under our policy?” — sets a clear expectation and creates a written record. That kind of upfront clarity saves headaches later.
The Tax Angle: Why Accountable Plans Matter
The way your employer structures reimbursement affects your taxes. Under an accountable plan, reimbursements are not considered wages — no income tax, Social Security, or Medicare deductions. To qualify, the plan must meet three conditions: the expense must be business-related, you must substantiate it within a reasonable time (generally 60 days), and you must return any excess reimbursement within 120 days (IRS Publication 463). Most employers who reimburse mileage use the IRS standard mileage rate as a safe harbor under an accountable plan.
If your employer uses a nonaccountable plan — for example, a flat monthly stipend with no substantiation requirement — the IRS treats those payments as taxable wages. That means you pay income tax on the reimbursement, and your employer pays payroll tax. Worse, since the Tax Cuts and Jobs Act suspended miscellaneous itemized deductions (and the One Big Beautiful Bill Act made that suspension permanent in 2025), W-2 employees cannot deduct unreimbursed business expenses on their federal return. So if you’re not reimbursed, every dollar you spend on business miles is out-of-pocket with no tax offset.
The practical takeaway: if your employer offers mileage reimbursement, ask whether it’s under an accountable plan. If it is, your reimbursements are tax-free. If it’s a flat allowance, expect to pay taxes on it — and consider whether that’s still worth driving your own car.
⚙️
The laws around mileage reimbursement for remote workers are a patchwork. Federal law offers a thin safety net for low-wage workers. A handful of states give you a clear right to reimbursement. Everywhere else, it comes down to company policy and your willingness to ask. What I’ve come to think is that the confusion isn’t necessarily bad faith — it’s that the rules were written for a world where most people commuted to a single office. Remote work broke that model, and the legal system is still catching up.
That doesn’t mean you should accept ambiguity. Know your state’s law. Keep a log. Ask for clarity in writing. And if you’re driving for work from your home, treat those miles as business miles until someone tells you otherwise — because the worst outcome isn’t getting denied; it’s not asking at all.
You now know that whether you’re owed mileage reimbursement depends on three things: your state’s law, your employer’s policy, and whether your home qualifies as a principal work location. You also know that accountable plans keep reimbursements tax-free, and that a clean mileage log is your best defense. The next time you drive for work from home, you’ll have a clearer sense of whether to track it — and how to ask for what you’re owed.
