How it works
What is a mileage deduction?
The IRS standard mileage method uses a cents-per-mile rate to estimate deductible vehicle costs for qualifying business use. Not all driving qualifies, and an estimated deduction is not the same as tax savings or a guaranteed deductible amount.
How the calculator works
Select a supported tax year and enter eligible business miles. For a single-rate year, the calculator multiplies total miles by that year's configured rate. For 2026, it calculates January–June and July–December mileage separately, adds the unrounded amounts, and rounds the final estimate to US cents.
Configured IRS business mileage rates
| Period | Business rate |
|---|---|
| 2024 full year | 67¢ per mile |
| 2025 full year | 70¢ per mile |
| January–June 2026 | 72.5¢ per mile |
| July–December 2026 | 76¢ per mile |
Business mileage and recordkeeping
Business mileage generally needs a qualifying business purpose and supporting records. Track mileage when it occurs, including the date, destination, distance, and purpose, and distinguish business trips from personal travel and ordinary commuting.
Standard mileage method versus actual expenses
The standard mileage method applies a published rate instead of adding the vehicle operating costs covered by that method. The actual-expense method uses eligible actual vehicle costs. Eligibility, method changes, and treatment of additional costs are subject to IRS rules, so avoid counting the same covered expense twice.
Example calculation
Illustrative 2026 example, separate from your calculation:
- January–June 2026 miles
- 6,000
- January–June 2026 estimate
- $4,350.00
- July–December 2026 miles
- 4,000
- July–December 2026 estimate
- $3,040.00
- Estimated mileage deduction
- $7,390.00
The calculation is 6,000 × $0.725 plus 4,000 × $0.76. It does not calculate tax savings or determine whether the miles qualify.
Frequently asked questions
What mileage can I enter as business mileage?
Enter vehicle travel that qualifies as business mileage under the rules that apply to you. Ordinary commuting generally differs from business travel, and not every work-related trip automatically qualifies. Keep records that explain the business purpose, date, and distance.
Is the estimated deduction the amount of tax I will save?
No. A deduction may reduce taxable income; it is not a dollar-for-dollar tax credit, refund, or guaranteed reduction in taxes owed. This calculator does not estimate tax liability.
Why does 2026 have two business mileage rates?
The configured IRS business rates are 72.5¢ per mile for January 1–June 30 and 76¢ per mile for July 1–December 31. The second rate took effect July 1, so mileage must be entered for the period in which it occurred.
Can I deduct fuel and maintenance in addition to the standard mileage rate?
The standard mileage method is an alternative to calculating the vehicle costs it is designed to cover. Do not use this estimate to separately claim the same covered operating expenses. Eligibility and treatment of other costs depend on IRS rules and individual circumstances.
Should I use the standard mileage method or actual expenses?
The methods use different calculations and eligibility rules. Compare the records and requirements that apply to your vehicle and situation; this page estimates only the standard mileage method and does not recommend a method.
Does this calculator provide tax advice?
No. It provides a US-focused estimate from configured IRS business mileage rates. It does not determine whether mileage is deductible or prepare a tax return. Consult current IRS guidance or a qualified professional when needed.
