Gas and car repairs when you log mileage

Short answer: if you log your business miles, you don't add gas or repair receipts. The IRS mileage rate already includes them.

Why

There are two ways to deduct a car you use for work:

• Standard mileage rate: every business mile is worth a set amount (72.5¢ a mile for January to June 2026, 76¢ from July 1). That amount covers gas, oil changes, repairs, tires, insurance and wear. Most one-person businesses use this, and it's what Tallibook does when you log trips.
• Actual expenses: you add up what the car really cost (gas, repairs, insurance and so on) and deduct the business share. You and your tax preparer choose this per vehicle, and you can't use both methods for the same car.

What to add as an expense when you log miles

Add these, in Parking & tolls:

• Parking for a business trip
• Tolls on a business trip

Don't add these, because the mileage rate already covers them:

• Gas, oil changes, repairs, tires and car washes
• Car insurance and registration

What if I already added gas receipts?

Nothing breaks. Gas and repairs you file under Vehicle costs (actual) are kept on record, but whenever you've logged business miles, Tallibook leaves them out of your deduction so they're never counted twice. Your Schedule C summary puts the mileage deduction plus parking and tolls on line 9.

Tallibook only uses Vehicle costs (actual) on line 9 if you haven't logged any business miles. If you and your tax preparer decide on actual expenses, stop logging trips for that car and add every car cost under Vehicle costs (actual).

Bank imports

When you import a bank statement, gas station charges are suggested as Vehicle costs (actual). If you use the mileage rate, you can mark them Personal in To review instead, so they don't clutter your business expenses. See Business or personal.
