Frequently asked questions
What is the IRS standard mileage rate?
For 2025 business use it is 70 cents per mile. Charitable, medical and moving rates are lower and are not used here.
Can I deduct actual expenses instead?
Yes, but you generally cannot switch methods freely after using standard mileage in the first year you own the car. Ask a tax professional.
Does commuting count?
Commuting between home and a regular workplace is not business mileage.
