No pressure. Just a friendly conversation.
Standard Mileage = Business Miles × IRS Rate; Actual Expense = Total Vehicle Expenses × Business Use %
The Standard Mileage method multiplies business miles by the IRS rate (67 cents for 2025). The Actual Expense method takes your total vehicle costs and applies your business use percentage.
The IRS allows two methods for deducting business vehicle expenses, and the difference can be substantial. The standard mileage rate simplifies record-keeping but may undervalue expensive vehicles or high-expense situations.
The actual expense method captures your real costs including gas, insurance, maintenance, repairs, registration, and depreciation. For luxury vehicles or in high-cost areas, this often provides a larger deduction.
Important: If you use actual expenses in the first year you use the vehicle for business, you cannot switch to the standard mileage rate later. However, if you start with standard mileage, you can switch to actual expenses in future years.

For 2025, the IRS standard mileage rate for business use is 67 cents per mile. This rate is adjusted annually based on fixed and variable vehicle operation costs. The rate covers gas, maintenance, insurance, depreciation, and other vehicle expenses.
Actual vehicle expenses include gasoline, oil, repairs, tires, insurance, registration, licenses, and depreciation (or lease payments). You multiply total expenses by your business use percentage. You must keep detailed records of all expenses.
Yes, if you use multiple vehicles for business, you can choose different methods for each. However, the first-year restriction applies per vehicle - once you use actual expenses for a vehicle, you cannot switch that vehicle to standard mileage.
