Printable Mileage Log Template: Free IRS-Compliant Log + How to Use It

Why your mileage log matters more than you think

A mileage log is the only thing standing between you and a denied deduction. If you claim vehicle expenses using the standard mileage rate, whether as a self-employed contractor or through an employer reimbursement policy, the IRS wants proof that the trips happened and were genuinely for business. No log, no deduction, even if every mile really was work-related.

The good news is that a compliant log is not complicated. It just has to be complete, accurate, and built up trip by trip rather than guessed at come tax season. This guide gives you a printable template and a short routine for keeping it airtight.

What the IRS actually requires in a mileage log

Under IRS Publication 463, an adequate mileage record needs four things for every trip: the date, where you started and ended up, the business purpose, and the mileage driven (or your odometer readings). You also need a beginning-of-year and end-of-year odometer reading for the vehicle, so you can show what share of your total driving was business use.

“You should record the elements of an expense or of a business use at or near the time of the expense or use and support it with sufficient documentary evidence.”

— IRS Publication 463, Travel, Gift, and Car Expenses

That phrase, 'at or near the time', is the whole game. The IRS calls this a contemporaneous record. It means logging the trip the day it happens, or within a few days at the outside, not reconstructing three months of driving from memory in April. A log built after the fact carries far less weight in an audit, even if every figure in it happens to be correct.

The printable mileage log template

Copy the table below into a spreadsheet, print it out, or recreate it in a notebook you keep in the car. The columns match exactly what the IRS asks for, plus a rate and amount column so the log doubles as your reimbursement or deduction record. Rows below show realistic entries using the current 2026 business rate of 76¢ per mile, effective from 1 July 2026 (trips before that date use the earlier 72.5¢ rate instead).

If you would rather have the maths done for you, run each trip through the mileage reimbursement calculator instead of working out the rate by hand. It applies the current IRS rate automatically, so there is no risk of totting up an old year's figure by mistake.

How to use the log: 7 steps

1. Log the trip as you drive it, not at the end of the day. Note the starting location and destination the moment you set off, ideally from your phone or a notepad kept in the car. This is what makes the record contemporaneous.
2. Write down the odometer reading, or your best mileage estimate, at the start and end of the trip. If you use GPS or a maps app, the trip distance it reports is acceptable as long as you record it at the time.
3. State the business purpose specifically. 'Client meeting — Q1 contract renewal' holds up in an audit; 'business' or 'meeting' does not, because it gives an examiner nothing to verify.
4. Total your miles at the end of each week. A weekly total is still considered timely under IRS rules, so this is a reasonable point to catch and fix any gaps before they pile up.
5. Apply the IRS standard mileage rate in effect on the travel date to convert miles into a dollar amount. For 2026, that's 72.5¢ per business mile from 1 January, rising to 76¢ from 1 July after a mid-year adjustment. Multiply each week's miles by the rate that applied when you drove them to get the amount owed or deductible.
6. Roll your weekly totals into a monthly summary for your books, your expense report, or your tax return. This monthly figure is what most bookkeeping software and reimbursement forms actually ask for.
7. Record your odometer reading on 1 January and 31 December each year. This annual reading lets you calculate the percentage of total driving that was business use, which the IRS uses to sanity-check your claim.
8. Store the completed log securely, on paper and as a digital backup, and hold onto it for at least three years after you file the return that relies on it.

Common mistakes that get mileage logs rejected in an audit

• Reconstructing the whole log from memory at tax time, rather than keeping it as trips happen. Auditors are trained to spot logs with suspiciously round numbers or identical handwriting written all at once.
• Vague or generic purposes such as 'client work' or 'errand', which give no detail an examiner can check against a calendar or invoice.
• Including ordinary commuting miles from home to a regular workplace. Commuting is never deductible, and mixing it into a business log undermines the whole record.
• Missing the beginning and end-of-year odometer readings, which the IRS uses to confirm your business-use percentage against total mileage.
• Applying the wrong year's rate, or switching rates partway through without noting when the change took effect.
• Leaving gaps of weeks or months between entries, which suggests the log was not kept at or near the time of travel.

How long to keep your mileage records

Keep every completed mileage log, along with the tax return it supports, for at least three years from the date you file. That covers the standard IRS audit window for most returns. If you understated income by a significant margin, the window can stretch further, so many self-employed workers simply keep logs for six years to be safe. If you are claiming the deduction as an employee or self-employed contractor, the same retention rule applies to your copy of the log even if your employer or client also holds one.

Paper logs work, but they are easy to lose and easy to forget. If you drive often for work, a mileage tracking app that logs trips automatically and exports a report in this same format removes most of the discipline this template demands.
