FAQ

Questions

How does the mileage deduction work?+

You multiply your business miles by the per-mile standard rate set by the IRS for that year. Only genuine business driving qualifies.

What rate should I use?+

Use the current IRS standard business mileage rate for the tax year, which changes annually. Enter it in the rate field. Your accountant can confirm it.

What records do I need?+

A mileage log kept as you drive, showing date, business purpose and miles. This is far stronger than an estimate made at tax time.
