IRS Requirement: To claim the standard mileage deduction, you must keep a contemporaneous log with the date, destination, business purpose, and miles for each trip. This tool helps you maintain an IRS-compliant record. Keep this log with your tax records.

How to Use This Mileage Log

Click "+ Add Trip" to log each business trip. Enter the date, destination, business purpose, and your odometer readings (start and end). The tool automatically calculates miles driven and your tax deduction at the current IRS rate.

IRS compliance tip:Log trips as they happen or shortly after. The IRS requires a "contemporaneous" record — meaning you kept it at or near the time of each trip. A reconstructed log at year-end will not hold up in an audit.

Frequently Asked Questions

What is the IRS standard mileage rate for 2026?
The IRS standard mileage rate for 2026 is $0.70 per mile for business use. This rate covers gas, insurance, depreciation, maintenance, and other vehicle costs. The rate is updated annually by the IRS, typically announced in December for the following year.
What records does the IRS require for mileage deductions?
The IRS requires a contemporaneous log with: (1) the date of each trip, (2) the destination, (3) the business purpose, (4) the odometer reading at start and end (or total miles). The log must be kept at or near the time of each trip — reconstructed logs at year-end are not accepted. This tool helps you maintain an IRS-compliant record.
Standard mileage rate vs. actual expenses — which is better?
The standard mileage rate ($0.70/mile in 2026) is simpler — multiply miles by rate. Actual expenses require tracking gas, insurance, repairs, depreciation, registration, and calculating business-use percentage. The actual method often yields a larger deduction for expensive vehicles or high maintenance costs, while standard mileage is better for fuel-efficient or newer vehicles.
Is this mileage log really free?
Yes, 100% free with no signup. All data stays in your browser's localStorage — nothing is sent to any server. Export as CSV or print as PDF anytime.
What counts as business mileage?
Business mileage includes trips to client meetings, job sites, the bank, post office, supply stores, airports for business travel, and between work locations. Commuting from home to your regular office is NOT deductible. However, if you have a qualifying home office, trips from home to client sites or other work locations do count.
Can I deduct mileage if I use my personal car?
Yes. If you use your personal vehicle for business purposes, you can deduct the business miles using either the standard mileage rate or actual expenses. You must track and separate business miles from personal miles. The IRS does not allow deduction for personal driving.
Do I need to track odometer readings?
The IRS technically requires odometer readings (start and end) for each trip. However, many tax professionals accept total trip miles calculated by GPS or mapping apps. Using odometer readings is the safest approach for an audit. This tool supports both methods.
How do I handle mixed-use trips?
If a trip has both business and personal purposes, only the business portion is deductible. For example, if you drive to a client meeting and then to a personal errand, log only the miles to and from the client meeting. Keep separate records for mixed-use trips.
