The 2026 Standard Mileage Rate
The IRS standard mileage rate for business driving rises to 67 cents per mile for 2026, up from prior years. The rate is the benchmark for employer reimbursements and for your deduction paperwork. Reimbursement below the rate is taxable wage up to the rate; reimbursement above the rate is taxable on the excess. The mileage log is your defense: dates, destinations, miles, and business purpose, stored 3 years minimum.
Home Office and Commuting Rules
Commuting from your home office to a client site is deductible when you are self-employed; as a W-2 employee, unreimbursed mileage is deductible only in a handful of states (California, New York, and a few others) on state returns. Remote workers who visit the office on a fixed schedule often have commuting mileage that stays non-deductible, while travel from home to client meetings qualifies. Keep the split in writing — see the home office tax guide for the boundary.
- Ask your employer for a per-mile reimbursement above the IRS rate; that portion is taxable.
- Log client-site trips from home in one file — they are the strongest deductions.
- Check state rules: only a few states allow W-2 mileage claims in 2026.
Reimbursement Plans That Keep More of Your Pay
An accountable reimbursement plan — mileage paid with substantiation — is tax-free to you and deductible to the employer. Un-accountable flat allowances are fully taxable wage. Before signing a remote policy, use the remote work request generator to ask for mileage handling in writing. Related guides: remote records for SSDI and the home office audit checklist.
Rule windows that move a mileage claim
Mileage is a reimbursement question before it is a tax question, and reimbursement rules are state rules. Several states mandate expense reimbursement for remote staff, including the costs required to do the work. The mandate creates the wage claim when reimbursement is refused, and the math follows the state rule, not the headquarters policy. Confirm the reimbursement rule in your working state with the state agency, and keep the final-pay window in view: the reimbursement line is owed on the same pay cycle as wages, and the window in the state where you worked is the date the claim is built from.
The split is the fact that matters. Travel from home to a client site is business travel; commuting to a fixed office schedule is not. Write the split in the log, and keep the remote approval email as the location proof — see remote termination jurisdiction.
What to document before you act
Keep one file, dated, for every reimbursable trip:
- The log line: date, origin, destination, miles, and the business purpose. Keep it for three years minimum.
- The remote approval email, with the work location named, so the client-site trips are home-to-business travel, not commuting.
- The reimbursement policy sentence: the per-mile rate, the substantiation required, and the submission deadline.
- The refusal, in writing, with the pay date. A refused reimbursement is a wage line, and a claim is built from the refusal, not from a meeting.
Numbers you should get in writing
Ask for four numbers before you drive: the per-mile rate the employer pays, the substantiation standard, the submission deadline, and the pay date for each reimbursement. Reimbursement up to the federal benchmark is the taxable line, and reimbursement above the benchmark is taxable on the excess; an accountable plan pays substantiated actual costs with no wage line for you and a deduction for the employer. That is why the accountable structure is the ask, and the flat allowance is the trap.
Then the self-employed side: home-office use is prorated by business-use percentage, and the receipts trail is the audit file. The paid-time line pairs with the mileage line: run the accrued balance through the PTO payout calculator before your last day, and put the reimbursement ask in the remote policy request with the remote work request generator.
Scripts and wording
Ask for the accountable plan, not the allowance:
“I am asking for mileage on an accountable reimbursement basis: I log each client-site trip with date, destination, miles, and business purpose, and the company reimburses at [rate] per mile on the next pay cycle. Can you confirm the rate, the substantiation standard, and the deadline in writing?”
Then keep the record. Save the request you sent and the answer you received with the timestamp. A reimbursement file built after access is cut is much weaker, and the demand letter for unpaid business expenses is written with the final pay check demand generator, quoting the state rule you confirmed with the state agency.

Frequently Asked Questions
- Is a flat mileage allowance taxable?
- A flat, un-accountable allowance is fully taxable wage. An accountable reimbursement paid against substantiated costs is not wage to you and is deductible to the employer.
- Is commuting from a home office deductible?
- For a W-2 employee, commuting mileage is not deductible except in a few states on state returns. Travel from home to a client site qualifies on the self-employed side.
- What proof does an audit ask for?
- The dated log with origin, destination, miles, and business purpose, plus the remote approval email naming the work location. Keep it three years minimum.
- Which state's rule applies to my reimbursement?
- The state where the work happened. Keep the location proof, and confirm the reimbursement mandate with the state agency before you file.
