2026 IRS Mileage Tax Deduction Calculator

What the 2026 IRS mileage rate actually covers

The IRS standard mileage rate is a single per-mile figure that bundles every cost of operating a vehicle for business: fuel, oil, maintenance, repairs, tires, depreciation, registration, and insurance. You take the deduction by multiplying your business miles by the rate — no receipts for individual gas fill-ups, no separate depreciation schedule, no proration of insurance.

For the 2026 tax year, the rate is 70 cents per business mile. That covers any vehicle you own or lease as long as you use the standard rate in the first year you place the vehicle in service for business. Two other rates apply for narrower categories:

The 70¢ rate is meaningful. A 12,000-mile year is an $8,400 deduction. At a 22% federal bracket plus 15.3% self-employment tax, that's roughly $3,100 less owed at tax time — for the same driving you'd be doing anyway.

Who can claim it

Eligibility is narrower than people think since the 2017 Tax Cuts and Jobs Act. As of the 2026 tax year, only these filers can deduct unreimbursed business mileage:

• Self-employed (Schedule C) — freelancers, contractors, sole proprietors, single-member LLCs.
• Landlords (Schedule E) — for travel between rental properties, to and from the bank for rental business, hardware store runs for rental supplies, meeting contractors on-site.
• Statutory employees — a narrow group whose W-2 box 13 is checked (full-time life insurance agents, certain delivery drivers, traveling salespeople).
• Armed Forces reservists, qualified performing artists, fee-basis state/local officials — the three remaining categories that can deduct unreimbursed employee expenses on Form 2106.

Most W-2 employees cannot deduct mileage for tax years 2018 through 2025 under TCJA. If your employer reimburses mileage at less than the IRS rate, the gap is not deductible — push for full reimbursement instead.

Standard mileage vs actual expenses

The IRS gives you a choice: the standard rate above, or "actual expenses" — sum up your fuel, oil, maintenance, repairs, insurance, registration, lease payments, and depreciation, then multiply by your business-use percentage. Three rules decide which one wins:

• Simpler: standard rate, by a wide margin. No receipts, no proration math, no depreciation schedule.
• Usually larger: standard rate for most ordinary vehicles. Actual expenses tend to win only when the vehicle is expensive to own (luxury cars, heavy-duty trucks, lease payments above ~$700/mo).
• Lock-in: if you start with actual expenses on a vehicle, you must keep using actual expenses for that vehicle for as long as you own it. Starting with the standard rate keeps both options open in future years.

Default recommendation: start with the standard rate. Switch to actual expenses only if a tax pro runs the numbers and tells you the gap is real for your specific vehicle.

What counts as a "business mile" (and what doesn't)

Counts as business mileage:

• Driving from your home office to a client site (if you have a qualifying home office; otherwise commuting rules apply).
• Driving between two work locations on the same day.
• Trips to the bank, post office, office supply store, or hardware store for business reasons.
• Meetings with clients, vendors, accountants, lawyers.
• For landlords: travel between rental properties, trips to show units, contractor meetings at properties, hardware/supply store runs for rental work.
• For rideshare/delivery: every mile from going online to going offline on the platform, plus reasonable miles between gigs.

Does NOT count:

• Commuting between home and your regular workplace, ever.
• Personal errands tacked onto a business trip (track only the business portion).
• Travel to a job site that's treated as a regular workplace.
• For landlords: trips to a property used personally for more than 14 days a year (it becomes a personal residence, not a rental).

What an IRS-defensible mileage log looks like

Audits of mileage deductions are common because the IRS knows most people don't keep contemporaneous records. To survive an audit, your log needs four columns for every business trip:

• Date of the trip.
• Destination (address or business name).
• Business purpose ("met with client X to scope project", "supply run for property Y", "delivery shift on DoorDash").
• Miles driven (or starting and ending odometer).

A spreadsheet works. A paper notebook works. What does not work is reconstructing the log six months later from memory and credit-card statements — auditors routinely disallow logs that don't show contemporaneous entry.

An automatic mileage tracking app (the kind that runs in the background on your phone, logs every trip via GPS, and lets you swipe-classify each one as business or personal) produces a defensible log without manual entry. PayStream Pro's iOS app ships this for self-employed users and landlords — every trip is timestamped, mapped, and exportable as an IRS-formatted PDF at year-end.

Worked examples

Where the deduction goes on your return

• Schedule C (self-employed, 1099, rideshare): Part II, line 9 "Car and truck expenses." Also complete Part IV (vehicle information).
• Schedule E (rental income): Line 6 "Auto and travel."
• Partnership / S-corp: the entity claims the deduction on its 1065 or 1120-S, not on your personal return. If you use a personal vehicle on entity business, the entity should reimburse you under an accountable plan at the standard rate — the reimbursement is tax-free to you and a deduction for the entity.
• C-corp: employees (including owner-employees) cannot deduct unreimbursed mileage. The C-corp should reimburse under an accountable plan at the standard rate.

Common mistakes that get flagged

• Round-number logs (every trip is exactly 15 miles). Real trips have odd numbers. GPS-based logs avoid this automatically.
• Claiming both standard mileage and actual expenses for the same vehicle in the same year. Pick one.
• Claiming standard mileage on more than 5 vehicles at once in a fleet business. The IRS treats fleets above 5 vehicles as requiring actual expenses.
• Deducting commuting miles from home to a regular workplace. Always disallowed.
• Claiming mileage on a vehicle you took bonus depreciation or Section 179 on. You're locked into actual expenses for that vehicle.
