A log the IRS accepts, kept as you drive.
A calculator tells you what the miles are worth. The deduction only survives if each trip was written down at the time. ClaryBook keeps that log for you.
- ClaryBook prices every trip at the IRS rate in force on the trip date, so a June trip gets 72.5 cents and a July trip gets 76 cents without you looking anything up.
- Type an expense in plain words, like "parking 12", and it is booked with the date, vendor and amount.
- Your Schedule C worksheet lists the standard mileage total on line 9 in form order, ready to hand to your preparer.
The two 2026 rates

Questions
What does the IRS need in a mileage log?
For each trip: the date, where you went, the business purpose and the miles driven. It has to be recorded at or near the time of the trip, which the IRS calls a contemporaneous log. A total you rebuild from memory or a calendar at year end is an estimate, and in an audit the deduction is disallowed. Odometer readings at the start and end of the year help back up the total.
Why are there two rates for 2026?
The IRS set the 2026 business rate at 72.5 cents a mile in January, then raised it to 76 cents for trips on or after July 1, 2026 because of fuel prices. Each trip takes the rate in force on its date, which is why this calculator asks for the two halves of the year separately.
What counts as business miles?
Driving between work sites, to clients, to the bank or supply store, and for landlords, to and from a rental property to show it, collect rent or do repairs. Driving from home to your regular workplace is commuting and does not count. If you use one car for both, keep the log and enter the business share above.
Standard mileage or actual expenses?
The standard rate covers gas, maintenance, insurance and depreciation in one number. Parking and tolls for business trips are deducted on top of it. If you want the standard rate for a car, you generally have to use it in the first year that car is used for your business. This calculator is standard mileage only.
Where does the deduction go on my return?
For a sole proprietor or single-member LLC it goes on Schedule C, line 9, car and truck expenses. For a rental property it goes on Schedule E, line 6, auto and travel. Our guide to mileage on Schedule C walks through the lines.
