How It Works

Keeping driving sorted into business, medical, and charity categories is what makes a mileage deduction hold up, and this tool tracks each one. The IRS lets taxpayers deduct eligible miles at set rates, and 2026 is a split year: since July 1 the rates are $0.76 per mile for business, $0.235 for medical, and $0.14 for charity (IR-2026-29), while January-June trips use the earlier $0.725 and $0.205 figures. Logged accurately, those miles trim your taxable income while keeping you in line with IRS rules.

The total deduction comes from multiplying the miles in each category by its matching IRS standard rate. Business miles run at $0.76, medical miles at $0.235, and charity miles at $0.14 for the second half of 2026; adding the three category totals together gives your overall IRS mileage deduction for the period in question.

A defensible log records the date, the starting and ending odometer readings, the destination, and the purpose of each trip, which is exactly what substantiates the deduction in an audit. Trips that mix personal and business driving need the business portion clearly separated, or the deduction can be disallowed. A digital log or app cuts down on the errors that creep into hand-kept records and keeps the math accurate.

Example: Small Business Owner's Q1 2026 Deductions

  1. 1 Input the following mileage for Q3 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 * $0.76/mile = $1,140.00; Medical Deduction = 150 miles * $0.235/mile = $35.25; Charity Deduction = 50 miles * $0.14/mile = $7.00.
  3. 3 Your total IRS mileage deduction for Q3 2026 is $1,140.00 + $35.25 + $7.00 = $1,182.25.
  4. 4 This $1,182.25 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?
Since July 1, 2026 the IRS standard mileage rates are 76 cents per mile for business, 23.5 cents for medical and moving (military only), and 14 cents for charity (72.5/20.5 cents for January-June trips). 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.
