How It Works

Our Mileage Log Calculator helps you efficiently track and categorize your business, medical, and charity-related driving. This is crucial for maximizing your tax deductions, as the IRS allows taxpayers to deduct eligible mileage at specific rates, which for 2026 are projected to be $0.70 per mile for business, $0.22 per mile for medical, and $0.16 per mile for charity. By accurately logging your trips, you can significantly reduce your taxable income and ensure compliance with IRS regulations.

This calculator determines your total mileage deduction by multiplying the miles driven for each category by its corresponding IRS standard mileage rate. For instance, business miles are multiplied by $0.70, medical miles by $0.22, and charity miles by $0.16. The sum of these individual category deductions then provides your total IRS mileage deduction for the specified period.

Remember to maintain a detailed log with dates, starting and ending odometer readings, destinations, and the purpose of each trip to substantiate your deductions if audited. Avoid combining personal and business trips without clearly delineating the business portion, as this can lead to disallowed deductions. Using a digital log or app can simplify tracking and ensure accuracy, preventing common errors from manual record-keeping.

Example: Small Business Owner's Q1 2026 Deductions

  1. 1 Input the following mileage for Q1 2026: Business Miles: 1,500 miles, Medical Miles: 150 miles, Charity Miles: 50 miles.
  2. 2 The calculator will perform the following calculations: Business Deduction = 1,500 miles * $0.70/mile = $1,050.00; Medical Deduction = 150 miles * $0.22/mile = $33.00; Charity Deduction = 50 miles * $0.16/mile = $8.00.
  3. 3 Your total IRS mileage deduction for Q1 2026 is $1,050.00 + $33.00 + $8.00 = $1,091.00.
  4. 4 This $1,091.00 can be claimed on your 2026 tax return, reducing your taxable income and potentially lowering your overall tax liability. Consistent logging throughout the year ensures you capture all eligible deductions.

Frequently Asked Questions

What is the IRS mileage rate for 2026?
The 2026 IRS standard mileage rates are 70 cents per mile for business, 21 cents per mile for medical and moving (military only), and 14 cents per mile for charity. The business rate reflects fuel, insurance, depreciation, and maintenance costs.
How do I keep a valid mileage log for the IRS?
Record the date, destination, business purpose, and miles driven for each trip. You can use a paper log, spreadsheet, or mileage tracking app. The IRS requires contemporaneous records, meaning you should log trips at or near the time they occur, not reconstruct them at year-end.
Can I deduct my commute to work?
No. Commuting from home to your regular workplace is never deductible. However, driving from your workplace to a client site, a second work location, or a temporary work location is deductible. If you have a qualifying home office, driving from home to any work location is deductible.
