Frequently Asked Questions
What is the IRS standard mileage rate?
The IRS standard mileage rate for 2025 is $0.70 per mile, up from $0.67 in 2024. This rate covers gas, insurance, depreciation, maintenance, and other vehicle costs. You multiply your business miles by this rate for your deduction.
What counts as business mileage?
Business mileage includes driving to meet clients, traveling between work locations, going to the office supply store, driving to the bank for deposits, and business-related errands. Commuting from home to a regular office does NOT count, but driving from your home office to client sites does.
Standard mileage vs actual expenses — which is better?
Standard mileage is simpler and often better for fuel-efficient or older vehicles. Actual expenses can save more if you have a newer, expensive vehicle with high insurance, depreciation, and maintenance costs. You must choose one method for the first year you use a car for business.
How do I track business mileage?
Keep a mileage log recording the date, destination, business purpose, and miles driven. Apps like MileIQ or Stride make this easy. The IRS requires contemporaneous records — you can't estimate at year-end.
