According to the IRS, the standard mileage rate for 2026 is 65.5 cents per mile for business use. This rate applies to all vehicles, including cars, trucks, and vans.

How to Keep a Mileage Log for Business Use

Keeping a mileage log is essential for calculating your mileage deduction. You can use a notebook, spreadsheet, or mobile app to record your business miles. It's crucial to include the date, starting and ending points, and the purpose of each trip. You should also keep receipts for fuel, maintenance, and other vehicle expenses. By maintaining accurate records, you can support your mileage deduction in case of an audit.

State-Specific Mileage Deduction Tips

While the IRS mileage rate is the same across all states, there may be additional state-specific requirements or benefits. For example, some states offer additional deductions for certain types of vehicles or business use. It's essential to consult with a tax professional or review your state's tax laws to ensure you're taking advantage of all available deductions. In California, for instance, you can deduct the business use percentage of your vehicle registration fees. In Texas, you can deduct the business use percentage of your vehicle insurance premiums.
