Business Mileage Tracker

Overview

Tracks business miles driven and calculates the IRS mileage deduction. Cross-references fuel, toll, and parking transactions to validate driving activity. You must choose between the standard mileage rate and actual vehicle expenses for each vehicle -- you cannot use both methods for the same vehicle in the same year.

Wilson Tools Used

• transaction_search — Find gas station, toll, and parking transactions to cross-reference against mileage logs
• export_transactions — Export vehicle-related expenses for recordkeeping

Workflow

1. Ask for the total business miles driven (Wilson cannot track odometer readings directly).
2. Multiply business miles by the current IRS standard mileage rate: $0.70/mile for 2025 (verify the current year rate at irs.gov).
3. Use transaction_search to find transactions matching gas stations, toll charges, and parking fees.
4. Cross-reference driving-related transactions against the mileage log dates to validate consistency.
5. Calculate the deduction: business_miles x rate_per_mile.
6. Report the deduction amount for Schedule C, Line 9 (Car and truck expenses).
