You spend a lot of time in your car on business. Fortunately, if your company doesn’t reimburse you for that mileage, a tax deduction is available on your federal tax return.
Deducting Mileage for Work
You can decide whether to use the IRS’ standard mileage rate for your own car or use the actual expenses method, which includes claiming petrol on your tax return, along with oil, insurance, tires, repairs, registration, licenses and other costs as a percentage of all business-related miles. If your car is used only for business purposes, you can deduct 100 percent of your expenses.
Standard Rate Versus Actual Expenses
The IRS requires that taxpayers use the standard mileage rate when an owned vehicle is used for the first time as a business vehicle. After that initial year, you can either use the standard mileage rate or go the actual expenses route. If you lease the vehicle, you must use the standard mileage rate for the entire length of the lease, including renewals. If using the actual expenses method on your tax return, gas receipts are needed for proof of your costs in case of an audit. However, if you use any depreciation method for your vehicle under the Modified Accelerated Cost Recovery System, you cannot claim a standard mileage rate. The same holds true if you use a Section 179 deduction for the vehicle. You can still use the actual expenses method and include depreciation of the vehicle in your calculations.
If you use the actual expenses method, you must keep careful records, including the price of fuel. Using the standard deduction method does not require as much recordkeeping, and it is easier to determine your costs. If you aren’t sure which method works best for your situation, calculate costs based on both methods and see where you get the larger deduction.
