IRS mileage rates and the standard vs actual method

The rates RevvFi uses

The IRS raised the rate in the middle of 2026, so each trip is priced at the rate in effect on its own date, not by tax year. When a new year's rate is published RevvFi updates it; earlier years are never changed, so old returns recompute the same way.

How a trip's deduction is computed

Business trip: miles × the rate for that date, rounded to the cent. Personal trip: $0. There is no partial business percentage on a trip; it is business or it is not.

Standard mileage rate vs actual vehicle expenses

On the Mileage screen's Settings tab, IRS mileage method offers Standard mileage rate or Actual vehicle expenses. The IRS lets you use only one per vehicle.

• Standard: your deduction is the miles × rate figure above. Vehicle cost categories (gas, insurance, repairs, the car payment) are not counted as deductions, since the rate already includes them. Those transactions show Not counted. You use the standard mileage rate.
• Actual: your mileage deduction is $0 (the miles are still recorded), and your actual vehicle costs count instead, by the business-use percentage you entered for the vehicle.

If you have not chosen, RevvFi uses standard whenever you have business miles for the year. The choice is for your whole account, not per business or per trip.

Which method deducts more?

With a vehicle set up (year, make, model, purchase price, ownership, payments, insurance, fuel, maintenance, registration, annual miles and business-use percentage) the Mileage screen compares both methods and marks one Recommended. The actual side includes loan interest (not principal) and straight-line depreciation. It is a comparison to help you decide, not tax advice.
