IRS Mileage Rate 2026: The Complete Guide

Every January, the Internal Revenue Service announces the standard mileage rate — a number that quietly affects tens of millions of Americans, from gig workers to HR departments to self-employed freelancers. For 2026, the IRS business mileage rate is $0.70 per mile — the same as 2025.

What Is the IRS Standard Mileage Rate?

The standard mileage rate is an optional method the IRS provides for calculating the deductible cost of using a personal vehicle for work. Instead of tracking every individual expense — gas, oil changes, insurance, depreciation — you simply multiply the total business miles driven by the IRS rate. The result is your allowable deduction or reimbursement amount.

The IRS recalculates the rate each year (and sometimes mid-year) based on a study of fixed and variable vehicle operating costs conducted by an independent contractor. In recent years, fuel price volatility has caused the IRS to issue mid-year updates — something to watch for throughout 2026.

Who Uses the 2026 IRS Mileage Rate?

Employees

If your employer reimburses you for business driving, the IRS rate sets the ceiling for tax-free reimbursement. Any reimbursement at or below $0.70/mile paid under an accountable plan is completely tax-free — no W-2 reporting, no income tax owed. Amounts above $0.70/mile must be reported as taxable wages.

Employers & HR Departments

Using the IRS rate as your reimbursement rate is the safest and simplest policy. It's the de facto standard for mileage reimbursement policies, gives employees a predictable rate, and eliminates payroll tax liability on those payments.

Self-Employed & 1099 Workers

Freelancers, contractors, and sole proprietors deduct business miles on Schedule C. At $0.70/mile, a self-employed worker who drives 15,000 business miles can deduct $10,500 from their gross income — reducing both income tax and self-employment tax (15.3%).

Gig Economy Workers

Rideshare drivers (Uber, Lyft), delivery drivers (DoorDash, Instacart, Amazon Flex), and other platform workers can deduct mileage for every mile driven on the job. Given that the average gig driver logs 20,000–30,000 work miles per year, this deduction is worth $14,000–$21,000 in deductible income at 2026 rates.

2026 vs. Historical IRS Rates

Standard Mileage Rate vs. Actual Expense Method

You have two choices when deducting vehicle costs: the standard mileage rate or the actual expense method. Here's when each makes sense:

• Standard mileage rate ($0.70/mile): Simpler, requires only a mileage log. Best for fuel-efficient or high-mileage vehicles. You cannot use it if you previously claimed MACRS depreciation on the vehicle.
• Actual expense method: Tracks real costs — gas, insurance, repairs, depreciation. Better for expensive vehicles or those with high operating costs. Requires detailed expense records all year.

Most freelancers and employees use the standard rate because of its simplicity. You must choose a method in your first year of business vehicle use, and switching later has restrictions.

How to Calculate Your 2026 Mileage Reimbursement

The math is straightforward: miles driven × $0.70 = reimbursement amount.

Documentation the IRS Requires

To claim the mileage deduction or receive a tax-free reimbursement, you must maintain a contemporaneous mileage log that records:

• The date of each business trip
• The starting location and destination
• The business purpose of the trip
• The number of miles driven

"Contemporaneous" means recorded at or near the time of the trip — not reconstructed at year-end from memory. Apps and spreadsheets both qualify.
