The actual expense method requires logging every cost associated with operating your vehicle and deducting the business-use share. It's more paperwork than the standard rate but can produce a larger deduction for expensive vehicles, high-insurance areas, or drivers with low annual mileage.
Deductible costs:
- Gas and oil
- Maintenance and repairs
- Tires
- Insurance premiums
- Registration and fees
- Lease payments (if leased)
- Depreciation (if owned), using MACRS schedules
- Garage rent
You then multiply the total by your business-use percentage (business miles / total miles for the year). Example: $9,000 total annual vehicle costs × 75% business use = $6,750 actual expense deduction.
Important lock-in: if you choose actual expense in the first year you use a vehicle for business, you're locked into that method for the vehicle's entire useful life. You cannot switch to standard mileage later. The reverse is allowed — start with standard, switch to actual.
For most rideshare and delivery drivers (high annual mileage, average car), the standard rate beats actual expense. The break-even is usually around 15,000–20,000 business miles per year on a moderately-priced vehicle.
