The two methods
Standard mileage rate: business miles × $0.70 (2025). Simple, and usually larger for an ordinary car. Actual expenses: the business-use percentage of gas, insurance, repairs, depreciation, and lease payments. Better for expensive or heavily driven vehicles. You choose a method in the first year the car is used for business; if you want the flexibility to switch later, start with the standard rate.
Which miles count
- Deductible: driving to clients and job sites, supply and bank runs, and between work locations. For gig drivers, miles with a passenger or delivery and driving to the next pickup.
- Not deductible: your commute from home to a regular workplace, and personal trips.
- On top of the rate: tolls and parking are deductible separately.
A qualifying home office can turn drives that would be non-deductible commuting into deductible business miles, because your trips start from your principal place of business.
Keep an IRS-proof log
The IRS wants a contemporaneous record: the date, miles, and business purpose of each trip, plus your total annual mileage. Reconstructing it in April rarely holds up. Log trips as they happen with a mileage app or a tool like NeoReceipt, which records your business miles at the IRS rate alongside your receipts, so your deduction is documented and audit-ready.
