Frequently asked questions
What rate per mile should I use?
For 2026, the IRS standard business mileage rate is 72.5 cents per mile. If your employer sets its own rate, use that one. The IRS rate changes every year, so check the current figure before you pay.
Does this include parking or tolls?
No. Add parking, tolls and other receipts separately, since they are usually reimbursed on their own.
