If your car is part of how you earn a living — client visits, deliveries, rideshare trips, property showings — your vehicle is quietly one of your largest deductible expenses. The question is which of the two IRS-approved methods puts more money back in your pocket: the standard mileage rate, or actual expenses.
Method 1: The standard mileage rate
Every business mile you drive is worth a flat, IRS-published rate per mile for the current tax year. Multiply your total qualifying business miles by that rate, and the result is your deduction — full stop. No fuel receipts, no repair invoices, no depreciation schedules.
Method 2: Actual expenses
Instead of a flat rate, you total every real cost of operating the vehicle for the year — gas, insurance, maintenance, lease payments or depreciation, registration — then multiply that total by your business-use percentage (business miles ÷ total miles driven).
| Scenario | Standard mileage often wins when | Actual expenses often wins when |
|---|---|---|
| Vehicle age | Newer, fuel-efficient vehicle | Older vehicle with high repair costs |
| Business-use % | Moderate business use | Very high business use (70%+) |
| Recordkeeping appetite | Prefer simplicity | Willing to save every receipt |
The rule you cannot break
You must choose the standard mileage rate in the very first year you use a vehicle for business if you ever want the option to switch methods later. Start with actual expenses in year one, and you are locked out of standard mileage for that vehicle going forward. Choose carefully.
Gig drivers: this is your single biggest deduction
For rideshare and delivery drivers, mileage is frequently the largest line item on the entire return. Our dedicated breakdown, Uber and Lyft Driver Tax Deductions: The Complete Checklist, walks through exactly which miles count — including the often-missed miles driven between trips while the app is on and waiting for a ride request.
What you can never deduct twice
Commuting from your home to a single fixed location where you always start work is personal mileage, not business mileage, even for the self-employed. The moment you have multiple job sites, client visits, or a qualifying home office as your principal place of business (see our home office deduction guide), the calculus changes in your favor — trips from a qualifying home office to client sites generally do count as deductible business miles.
Frequently asked questions
What is the standard mileage rate deduction for this year?
The IRS adjusts the rate annually, sometimes mid-year during periods of high fuel volatility. Enter your total business miles into our calculator to see the current-year dollar deduction instantly.
Can I switch between methods every year?
Only if you used standard mileage in the first year the vehicle was placed in service. If you started with actual expenses, you must continue using actual expenses for that vehicle.
Does parking and tolls count separately?
Yes. Business-related parking fees and tolls are deductible in addition to whichever mileage method you choose — they are not baked into the per-mile rate.
