TaxMiles uses GPS and motion sensors to detect when you start driving at speeds above 10 mph. It records your route in the background with less than 3% battery impact. Trips end automatically after you've been stationary for 5+ minutes.
After each trip, you'll receive a notification. Swipe right for business, left for personal. You can also classify trips from the Trips tab. After 2 weeks, TaxMiles AI will start auto-classifying for you.
TaxMiles applies the rate that was in effect on the day each trip was driven — it never stamps today's rate onto older miles. The IRS changed the rate partway through 2026: 72.5¢/mile for January 1 – June 30 and 76¢/mile from July 1. Your 2026 log therefore contains two rates on purpose, and your reports split it for you.

Standard mileage — business miles × the IRS rate — usually wins for higher-mileage or cheap-to-run cars. Actual expenses (gas, insurance, registration, repairs, lease, depreciation, prorated by business use) often wins for newer or pricier cars driven fewer miles. Open Taxes → Tax Toolkit → Compare Methods and TaxMiles works out both from your own data. Note you must pick standard mileage in the first year you use a car for business to keep that option open later.
Often. You generally have three years from the filing deadline to amend with Form 1040-X. Taxes → Tax Toolkit → Prior Years totals what went unclaimed in each prior year and estimates the refund. Build an Audit Packet first so your preparer has the substantiation.
Yes to all three. The Watch app starts and stops drives from your wrist and adds complications to your watch face. CarPlay (Pro) puts trip control on your car's screen with live miles and deduction. On iOS 18 you can add a Start Trip control to Control Center, and Siri understands "Start a trip in TaxMiles."
Taxes → Tax Toolkit → Audit Packet gathers your mileage log, audit certificate, odometer photos and receipt images into a single dated folder with a README explaining each file, then zips it so you can email or AirDrop it in one piece. Worth building once a year when you file.
Not federally — that deduction has been suspended since 2018. But several states never adopted the suspension, so your miles may still count on your state return. Taxes → Tax Toolkit → State Rules shows where your state stands. Self-employed workers are unaffected.
