About

WriteOffRoad is a web-based travel tax deduction calculator designed for remote workers, freelancers, and 1099 contractors who travel for work but don’t manually track every trip.

The platform converts Google Maps Timeline location data into organized, IRS-compliant per diem and mileage deduction reports in minutes. Instead of reconstructing travel manually, users can upload their Google Timeline JSON export, set a home location, and instantly identify qualifying work travel.

WriteOffRoad automatically detects trips more than 50 miles from home, applies the correct IRS and GSA per diem rates based on location and date, and calculates meals, incidentals, lodging, and mileage deductions. It handles multi-day travel, seasonal rate changes, fiscal year boundaries, and IRS partial-day rules.

Users can categorize trips as business or personal and export detailed reports to Excel, CSV, or PDF for use with tax preparers or recordkeeping. The platform supports U.S. and international travel and includes historical rate data for amending prior year returns.

WriteOffRoad is built for modern work patterns — including remote professionals, contractors, consultants, sales reps, photographers, and mobile workers — where travel is frequent but documentation is difficult.

During tax season, the tool helps users uncover thousands of dollars in missed deductions while reducing the time required to prepare travel documentation.

All calculations follow IRS Publication 1542 guidance and use official rate tables from the GSA, Department of Defense, and U.S. State Department.
