Are Tolls and Parking Deductible? Yes — On Top of Your Mileage

The standard mileage rate is a stand-in for what it costs to operate a car: fuel, oil, tires, maintenance, repairs, insurance, registration and depreciation. Tolls and parking are not operating costs of the vehicle — they are costs of a particular trip. So they sit outside the rate and get deducted on top.

This holds under both methods. Standard rate or actual expenses, business tolls and parking are separately deductible either way.

What counts

• Tolls paid on a business trip — bridges, turnpikes, express lanes, congestion charges.
• Parking meters, garages and lots at a client, job site, supplier or business meeting.
• Airport parking for a business trip.
• Parking at a temporary work location.

What does not

• Parking at your own regular workplace. That is part of commuting, and commuting costs are personal. The monthly garage spot next to the office you drive to every day is not deductible.
• Tolls on a commute, for the same reason.
• Parking tickets and traffic fines. Fines paid to a government for breaking the law are never deductible, no matter how business the trip was. A ticket collected while making a delivery is an expensive delivery, not a write-off.
• The personal share. If a toll road carried you to both a client and your own weekend plans, only the business portion is deductible.

Keep the receipt — here the receipt is the proof

Under the standard rate you do not need fuel or repair receipts, which leads people to stop keeping receipts at all. Tolls and parking are the exception: they are separate expenses, so they need their own records — amount, date, place and business purpose.

Electronic toll accounts make this easy. A monthly transponder statement lists every crossing with a date and amount; matched against your mileage log, it tells you which crossings were business without any guesswork. Parking is usually the harder one, because it is small, frequent, and paid in cash or through a dozen different apps — photograph the receipt when you pay, or log the amount then and there.

Where they go on the return

For a sole proprietor, business tolls and parking belong in car and truck expenses or other expenses on Schedule C — added to, not folded into, the mileage figure. If you file through a partnership or S corporation, they follow the same treatment as the rest of the vehicle expense under that entity's reimbursement or accountable-plan arrangement.

The rule of thumb is simple enough to apply in the moment you hand over the money: if the trip is deductible, the toll and the parking for it are too — and the receipt is what makes that claim survive a second look.
