Understanding the 2023 IRS Mileage Rates
For the 2023 tax year, the Internal Revenue Service (IRS) updated the optional standard mileage rates used to calculate the deductible costs of operating an automobile for business, charitable, medical, or moving purposes. This calculator uses the official rates set effective January 1, 2023.
Using the standard mileage rate is a simplified method for taxpayers to calculate their vehicle expenses without tracking actual costs for gas, insurance, repairs, and depreciation. Instead, you track your mileage and multiply it by the specific rate for your driving purpose.
Official 2023 Rates Breakdown
- Business Use: 65.5 cents per mile (up 3 cents from mid-2022).
- Medical & Moving: 22 cents per mile (for qualified active-duty members of the Armed Forces).
- Charitable Service: 14 cents per mile (set by statute).
How to Calculate Your Mileage Deduction
To determine your deduction, the formula is straightforward:
(Total Miles Driven) × (IRS Rate for Specific Purpose) = Total Deduction Amount
Example Calculation
If you are a freelance consultant and drove 2,500 miles in 2023 to visit clients, attend meetings, or perform job-related tasks, your calculation would be:
2,500 miles × $0.655 = $1,637.50
This amount can be deducted from your taxable income on your 2023 tax return, potentially lowering your tax liability.
Requirements for claiming the Deduction
While the calculation is simple, the IRS requires rigorous record-keeping to substantiate your claim. In the event of an audit, you must be able to provide a log containing:
- The date of the trip.
- The starting point and destination.
- The business purpose of the trip.
- The total miles driven for each trip.
- The total odometer reading at the start and end of the year.
Standard Mileage vs. Actual Expenses
You generally have the option to use either the standard mileage rate or the actual expense method. The actual expense method requires you to track every single vehicle-related cost (gas, oil, tires, insurance, registration, depreciation) and determine the percentage of business use vs. personal use. The standard mileage rate is popular because it reduces the paperwork burden significantly.
