Frequently asked questions

What is the IRS standard mileage rate for 2026?

The IRS standard mileage rate for 2026 business driving is $0.70 per mile. This rate is set by the IRS and updated periodically to reflect changes in fuel costs and vehicle operating costs.

Can I deduct miles driven to job sites?

Yes. Miles driven between your regular place of business and a job site — or between two job sites — are fully deductible business miles. Commuting from home to your first site of the day is not deductible unless you have a qualifying home office.

Standard mileage rate vs actual expenses — which is better?

The standard mileage rate is simpler and better for most independent contractors. The actual expense method (tracking fuel, insurance, depreciation, repairs) can yield a higher deduction if your car is expensive to run, but requires significantly more record-keeping. You must choose one method for the year.

Do I need a mileage log?

Yes. The IRS requires a contemporaneous mileage log — ideally recorded at the time of each trip. It should include the date, destination, business purpose, and miles driven. A simple notes app or spreadsheet works. Several apps can track this automatically using your phone's GPS.

What types of driving count as business miles for contractors?

Business miles include: driving to client sites and job locations, trips to pick up materials or supplies, driving to meet potential clients, bank runs for business deposits, and driving to business-related appointments (accountant, lawyer, supplier). Personal errands and standard commuting do not qualify.
