Standard Mileage vs Actual Expenses for 1099 Taxpayers
In short: Self-employed taxpayers can deduct business vehicle costs using either the standard mileage rate or the actual expense method, reporting the final deduction on Line 9 of Schedule C.
How the Standard Mileage Method Works
The standard mileage method simplifies your recordkeeping by multiplying your total business miles driven by a set cents-per-mile rate determined by the IRS. For the tax year 2026, the rate is 72.5 cents per mile from January 1 through June 30, and increases to 76 cents per mile starting July 1. To use this approach safely, you must maintain a reliable contemporaneous mileage log that records the date, miles driven, and business purpose of every trip. Furthermore, if you own your vehicle, you must elect the standard mileage method in the very first year the car is available for business use to remain eligible in later years.
How the Actual Expenses Method Works
Instead of relying on a flat mileage rate, the actual expense method allows you to deduct the exact business-use percentage of all operating costs tied to your vehicle. This includes gas, oil, repairs, tires, insurance, registration fees, lease payments, and vehicle depreciation. To calculate your deduction, you divide your total business miles by your total miles driven for the entire year to determine your business-use percentage, then apply that percentage to your aggregate vehicle expenses. This method typically requires keeping every receipt, bill, and maintenance record throughout the tax year to substantiate your calculations in the event of an IRS review.
Reporting Vehicle Deductions on Schedule C
No matter which calculation method you choose, your final vehicle deduction is reported on Line 9 of your Schedule C when you file your federal income tax return. It is important to note that certain driving costs are treated separately from your primary deduction choice. Specifically, business-related parking fees and road tolls are fully deductible under either the standard mileage method or the actual expense method, provided they are not already reimbursed. Keeping your daily business receipts organized makes it much easier to transfer these accurate totals to your tax forms or share them with software like Proofly before filing deadlines.

Frequently asked questions
Can I switch between standard mileage and actual expenses every year?
If you own your vehicle, you must choose the standard mileage method in the first year the car is in service if you want to use it in future years. If you use actual expenses in year one, you generally cannot switch to standard mileage later.
Are parking fees and tolls included in the standard mileage rate?
No, parking fees and tolls paid for business travel are deductible in addition to your standard mileage rate or actual expenses.
What records do I need to keep for the standard mileage method?
You must keep a manual mileage log recording each business trip's date, total mileage, and business purpose, along with odometer readings at the start and end of the year.
Where do I list vehicle expenses on my tax return?
Vehicle deductions are entered on Line 9 of your Schedule C, which is filed with your Form 1040 for self-employed business income.
