What is the IRS Standard Mileage Rate for 2025? (Calculator & Guide)
Every year, taxpayers who use their personal vehicles for business, medical, moving, or charitable purposes eagerly await the Internal Revenue Service (IRS) announcement of the standard mileage rates. These rates define how much you can deduct per mile driven for these specific activities on your tax return.
Important Note Regarding 2025 Rates: The official IRS standard mileage rates for the 2025 tax year are typically announced in December 2024. The calculator below uses projected rates based on current economic trends and inflation data to help you estimate your potential deductions for the upcoming year. The charitable rate is set by statute and rarely changes.

Understanding the Standard Mileage Rate Categories
To accurately use the calculator and prepare for your 2025 taxes, it is essential to understand the different categories recognized by the IRS:
- Business Mileage: This is the most common deduction. It covers deductible costs of operating an automobile for business purposes. This rate is typically the highest as it accounts for depreciation, insurance, repairs, tires, maintenance, gas, and oil.
- Medical and Moving Mileage: This rate applies to miles driven for primarily medical care purposes. It also applies to moving expenses, but only for qualified active-duty members of the Armed Forces moving due to a permanent change of station. This rate is generally lower than the business rate as it primarily covers variable costs like gas and oil.
- Charitable Mileage: This applies to miles driven in service of a charitable organization. This rate is fixed by federal statute at 14 cents per mile and does not fluctuate with fuel prices or inflation unless Congress passes new legislation.
How Are the 2025 Rates Determined?
The IRS determines the standard mileage rates based on an annual study of the fixed and variable costs of operating an automobile. This study considers factors such as current fuel prices, vehicle depreciation rates, insurance costs, and maintenance expenses. The rates in the calculator above are projections assuming modest increases based on inflationary trends seen leading into 2025. Always verify with the official release late in the year.
