IRS Mileage Rates: The Complete Guide to Maximizing Your Vehicle Tax Deduction

Every mile you drive for business could put money back in your pocket—but only if you know the rules. Yet many self-employed workers and small business owners either don't track their miles at all, or they use the wrong method and leave significant deductions on the table. With the 2026 IRS standard mileage rate now at 72.5 cents per mile, a single road warrior who drives 20,000 business miles annually can deduct $14,500. That's not small change.

This guide covers everything you need to know about IRS mileage rates, how to choose the right deduction method, what your records must contain, and how to make sure you capture every deductible mile.

What Are IRS Standard Mileage Rates?

The IRS sets standard mileage rates each year to simplify how individuals and businesses calculate the tax deduction for using a personal vehicle for certain purposes. Instead of tracking every gas receipt and oil change, you multiply your qualifying miles by the applicable rate.

2026 IRS Standard Mileage Rates

Effective January 1, 2026, the standard mileage rates are:

Purpose	2026 Rate	2025 Rate
Business use	72.5 cents/mile	70 cents/mile
Medical purposes	20.5 cents/mile	21 cents/mile
Charitable organizations	14 cents/mile	14 cents/mile

The business rate increased by 2.5 cents from 2025, reflecting higher vehicle operating costs. The medical rate dropped slightly, and the charitable rate—set by statute rather than annual cost studies—remains unchanged.

How the IRS Calculates These Rates

The business mileage rate is based on an annual study of the fixed and variable costs of operating an automobile: fuel, depreciation, insurance, maintenance, and tires. The medical and moving rates are based only on variable costs. Because the charitable rate is set by Congress rather than cost data, it hasn't changed since 1998.

Which Miles Qualify for a Deduction?

Not all driving is deductible. Understanding which miles count—and which don't—is essential.

Business Miles (72.5 cents/mile in 2026)

Business mileage includes driving to meet clients, travel between job sites, making bank deposits for your business, picking up supplies, and attending business-related conferences. Self-employed workers and business owners who file Schedule C, Schedule E, or Schedule F can claim this deduction.

What doesn't qualify: The most common mistake is treating commuting as a business expense. Miles driven between your home and your regular place of work are personal, not business, miles. Even if you do work in the car—listening to calls, for example—the IRS still considers that commuting. The only exception is if your home is your principal place of business, in which case travel from home to a client site may qualify.

Medical Miles (20.5 cents/mile in 2026)

You can deduct miles driven for medical care—traveling to doctor's appointments, hospitals, or medical treatment facilities—if you itemize deductions on Schedule A. The deduction only applies to the amount that exceeds 7.5% of your adjusted gross income.

Charitable Miles (14 cents/mile in 2026)

Miles driven while performing services for a qualified charitable organization may be deducted if you itemize. This includes delivering meals for a food bank, driving to a volunteer shift, or transporting supplies for a nonprofit. The rate is notably lower than the business rate because Congress set it decades ago and hasn't updated it.

Standard Mileage Rate vs. Actual Expense Method

When it comes to business vehicle deductions, you have two options: the standard mileage rate or the actual expense method. Choosing correctly can make a meaningful difference in your tax bill.

Standard Mileage Rate

Multiply your business miles by the IRS rate (72.5 cents in 2026). Done. This rate already accounts for fuel, depreciation, insurance, and maintenance. You can still deduct parking fees and tolls separately on top of the standard rate.

Best for: Drivers with fuel-efficient vehicles, lower ownership costs, or high annual business mileage. The simplicity also makes it easier to audit-proof your records.

Actual Expense Method

Track every dollar you spend operating the vehicle—gas, oil changes, tires, repairs, insurance, registration fees, loan interest, and depreciation—then multiply the total by the percentage of miles driven for business.

For example: if your total vehicle expenses for the year are $12,000 and 60% of your miles were for business, your deduction is $7,200.

Best for: Drivers with expensive vehicles, high fuel costs, or frequent repairs where true per-mile costs exceed 72.5 cents.

The Critical Switching Rule

Here's a rule many taxpayers learn the hard way: if you use the actual expense method in the first year you place a vehicle in service, you cannot switch to the standard mileage rate for that vehicle in any future year. However, if you start with the standard mileage rate, you can switch to actual expenses later (though depreciation rules get complicated).

The practical takeaway: in the first year you use a vehicle for business, calculate your deduction both ways. Whichever method you choose, make sure it's the right long-term decision for that vehicle.

IRS Mileage Log Requirements

The IRS requires "adequate records" to support a vehicle deduction. Vague entries, reconstructed logs, or a simple total at year-end won't survive an audit.

What Your Log Must Include

For every business trip, you need to record:

• Date of the trip
• Destination (city or address is sufficient)
• Business purpose (e.g., "client meeting with Acme Corp," not just "meeting")
• Miles driven for that trip

You also need odometer readings at the beginning and end of each year to verify total mileage. If you use a vehicle for both business and personal purposes, you must track all miles—not just business miles—to establish the business-use percentage.

Timing Matters

The IRS specifies that records should be made "at or near the time" of the trip. A weekly log is explicitly considered timely under IRS Publication 463. Reconstructing months of driving from memory at tax time is a major audit red flag—and often results in disallowed deductions.

Acceptable Formats

The IRS does not require a specific format. A handwritten logbook, a spreadsheet, or a digital app all work, as long as the required information is captured. Digital records are fully acceptable provided they contain all required fields and are backed up securely.

The Best Way to Track Mileage

Manual mileage logs work, but they're easy to forget. GPS-based mileage tracking apps are the most reliable solution for most self-employed workers and small business owners.

Popular Mileage Tracking Apps

• MileIQ – Automatically detects trips and lets you swipe to classify them as business or personal. Generates IRS-compliant reports.
• Everlance – Combines mileage tracking with expense tracking, useful for self-employed workers managing multiple categories of expenses.
• TripLog – Offers fleet tracking features in addition to individual mileage logging, useful for small businesses with multiple drivers.
• Driversnote – Automatically tracks trips and produces formatted mileage logs ready for tax filing or reimbursement.

These apps eliminate the risk of forgetting trips and capture precise GPS data, which strengthens your records if you're ever audited.

Manual Mileage Log Tips

If you prefer a manual approach:

• Keep a small notebook in your car or use a notes app on your phone
• Log each trip immediately after it ends
• Record odometer readings on January 1 and December 31
• Keep the log for at least three years after filing—or six years if the IRS has reason to suspect you underreported income

Common Mileage Deduction Mistakes to Avoid

1. Claiming Commuting Miles

This is the most frequent error. The drive from your home to your first work location (and back) is personal, not business. If you make additional stops for business purposes during a commute, only the detour portion may qualify.

2. Forgetting Tolls and Parking

Tolls and parking fees are deductible in addition to the standard mileage rate—they're not included in the 72.5 cent figure. Keep receipts or electronic records for these.

3. Not Comparing Both Methods

Too many business owners default to the standard mileage rate without checking whether actual expenses would yield a larger deduction. Run the numbers, especially if you're buying or leasing a new vehicle.

4. Using a Leased Vehicle Without Understanding the Rules

If you lease a vehicle and use the actual expense method, you must include an "inclusion amount" that reduces your deduction based on the vehicle's value. The standard mileage rate avoids this complication.

5. Waiting Until Tax Season to Log Miles

Reconstructed mileage logs rarely hold up under IRS scrutiny. A consistent, contemporaneous log protects your deduction.

Employee Business Mileage: The Post-TCJA Reality

One important note for employees: the 2017 Tax Cuts and Jobs Act eliminated the miscellaneous itemized deduction for unreimbursed employee expenses through 2025 (and currently through 2025 under law). Regular W-2 employees cannot deduct business mileage on their personal returns—only self-employed workers and business owners can.

If you're an employee who uses your car for work, your best path is to ask your employer to reimburse you at the IRS rate, which is tax-free to you if your employer uses an accountable plan.

How to Claim the Mileage Deduction

The form you use depends on your situation:

• Self-employed (Schedule C): Report vehicle expenses on Part II, Line 9, and complete Part IV (Information on Your Vehicle)
• Rental income (Schedule E): Deduct vehicle expenses as a rental expense
• Farmers (Schedule F): Deduct vehicle expenses related to farming
• Employees seeking reimbursement: Provide mileage logs to your employer; the employer deducts reimbursements as a business expense

If you use a vehicle for multiple purposes (business and medical, for example), you need to track each category's miles separately and report them on the appropriate forms.
