Vehicle Expense Deduction 2026: Mileage or Actual

If you drive for your business, the IRS gives you two ways to deduct the cost: a flat per-mile rate, or your actual car expenses split by how much you drive for work. For 2026 the standard mileage rate is 72.5 cents a mile, up from 70 cents in 2025. The actual expense method instead adds up real costs like gas, repairs, insurance, and depreciation, then deducts the business-use share. This guide walks through both methods, when each one wins, how to handle buying a vehicle, and the records the deduction rests on.

How do I deduct vehicle expenses for business?

You deduct business vehicle costs one of two ways: the standard mileage rate or the actual expense method. The standard mileage rate multiplies your business miles by a set per-mile figure (72.5 cents for 2026). The actual expense method adds up everything it costs to own and run the car for the year, then deducts the percentage that matches your business use. You pick one method per vehicle, and only the business portion of driving counts either way.

Both methods rely on the same starting point: knowing how many miles you drove for business versus personal use. That split drives the whole deduction, so a mileage record is not optional under either approach. The rules below come from IRS Publication 463, which covers car and truck expenses for the self-employed.

What is the standard mileage rate for 2026?

The 2026 IRS standard mileage rate for business driving is 72.5 cents per mile, set by IRS Notice 2026-10. That is up 2.5 cents from the 70 cents per mile that applied in 2025 under Notice 2025-5. You multiply your business miles for the year by the rate, so 8,000 business miles in 2026 produces a deduction of $5,800.

The rate already bakes in gas, oil, maintenance and repairs, tires, insurance, registration, and depreciation, so you cannot deduct those costs again on top of it. You can still separately deduct business-related parking fees and tolls, and if you are self-employed, the business-use portion of your car loan interest and any personal property tax on the vehicle. Note that part of the rate counts as depreciation that reduces your vehicle's tax basis: 33 cents per mile for 2025 and 35 cents per mile for 2026, which matters later if you sell the car.

What is the actual expense method?

The actual expense method deducts the business-use percentage of what the vehicle really costs you. You total the year's gas, oil, repairs, tires, insurance, registration and license fees, garage rent, and either lease payments or depreciation, then multiply by the share of miles that were for business. Drive 60% of your miles for work and your deduction is 60% of those total costs.

This method takes more bookkeeping because you have to keep every fuel and repair receipt and the insurance and registration bills, though a gas receipt tracker turns the pile of fuel slips into one dated spreadsheet. It tends to pay off when your car is expensive to run or you can claim large depreciation in the early years. Depreciation is where the math gets involved, which leads to the next point about buying a vehicle.

Standard mileage vs actual expenses: which should I use?

Run both and take the bigger deduction in your first year, because that choice can lock you in. The standard mileage rate usually wins for high-mileage, low-cost cars and for anyone who would rather not save every receipt. The actual expense method usually wins for expensive vehicles, heavy repair years, short business-mileage with high fixed costs, or the first year you can claim big depreciation or Section 179.

A simple way to decide: estimate your business miles times 72.5 cents, then estimate your actual costs times your business-use percentage, and compare. If the gap is small, the standard mileage rate saves you hours of record-keeping for roughly the same deduction. If you might buy a costly vehicle and want a large first-year write-off, the actual method with depreciation is the only path to it.

Can I switch between the standard mileage rate and actual expenses?

Sometimes, and the rules differ for owned and leased cars. If you own the car, you must use the standard mileage rate in the first year you put it in service for business if you ever want the option to use it later. After that first year you can switch between the two methods from year to year, with some limits on depreciation. If you start with the actual expense method in year one and claimed certain depreciation, you are generally stuck with actual expenses for that vehicle.

Leased cars work differently. If you choose the standard mileage rate for a leased vehicle, you have to use it for the entire lease, including renewals. That is why the first-year decision matters so much: it sets the rules for the rest of the time you have the car.

Can I write off my car payment?

Not the payment itself, but you can recover the cost of the vehicle other ways. A loan payment is part principal and part interest, and neither is deductible as a lump sum. Instead, the cost of the vehicle is deducted over time through depreciation (or wrapped into the standard mileage rate), and the business-use share of the interest is deductible separately if you are self-employed.

For a leased vehicle under the actual expense method, your lease payments are deductible based on business-use percentage, though high-value leases require an income inclusion adjustment from the IRS lease tables. So you do get to deduct the cost of using the car for business, just through depreciation, lease payments, or the per-mile rate rather than by writing off the monthly note.

Can I deduct car loan interest?

If you are self-employed, yes, you can deduct the business-use portion of your car loan interest on Schedule C, even when you use the standard mileage rate. Drive the car 70% for business and 70% of the interest is deductible. Employees cannot deduct car loan interest at all. This business interest deduction is completely separate from the new temporary deduction for personal car loan interest created by the 2025 budget law (the One Big Beautiful Bill Act), which is an above-the-line deduction of up to $10,000 a year for 2025 through 2028 on a new, US-assembled personal-use vehicle, and which does not apply to business vehicles.

Can I write off a vehicle purchase for my business?

Yes, but how much you can deduct up front depends on the vehicle's weight and how you use it. For a normal passenger car (gross vehicle weight rating of 6,000 pounds or less), the first-year depreciation is capped by the Section 280F luxury auto limits. For vehicles placed in service in 2026, the first-year cap is about $20,300 when bonus depreciation applies and about $12,300 without it. Those caps limit your deduction no matter how much the car costs or whether you use Section 179.

Heavier vehicles change the picture. A truck or SUV with a gross vehicle weight rating over 6,000 pounds is exempt from the passenger-auto caps. SUVs between 6,001 and 14,000 pounds have their own Section 179 limit (about $31,300 for vehicles placed in service in 2025, adjusted up for inflation), and the rest of the cost can often be written off with bonus depreciation. The One Big Beautiful Bill Act permanently restored 100% bonus depreciation for qualifying property acquired and placed in service after January 19, 2025, so a qualifying heavy business vehicle can frequently be expensed in full in year one. The vehicle still has to be used more than 50% for business, and the deduction is limited to the business-use percentage.

Is my commute to work deductible?

No. Driving between your home and a regular place of work is commuting, which the IRS treats as a personal cost that is never deductible, even if you do business calls on the way. This is one of the most common mistakes, so it is worth being clear: commuting miles are personal miles. Business miles are trips between work locations, to clients or job sites, to the bank or supplier, and similar errands once you have left your tax home base. If you have a qualifying home office that is your principal place of business, trips from there to other business stops can count as business miles.

Do I need a mileage log?

Yes. A car is listed property under the tax code, so it falls under strict substantiation rules: you need a record showing the date, the business miles, and the business purpose of each trip, along with your total miles for the year. A log kept at or near the time of each trip is far stronger than a guess reconstructed in April. The under-$75 rule that lets you skip receipts for small expenses does not remove the mileage requirement, so even if you use the standard mileage rate, the log is what proves the deduction. A mileage app, a calendar, or a notebook in the glovebox all work as long as the entries are contemporaneous and consistent.

Where do I report vehicle expenses on Schedule C?

Sole proprietors and single-member LLCs report the deduction on Schedule C, Line 9, Car and truck expenses. You also complete Part IV of Schedule C, Information on Your Vehicle (lines 43 through 47b), which asks for the date you placed the car in service, your business, commuting, and other miles, and whether you have written evidence. If you claim depreciation or a Section 179 deduction on the vehicle, you complete Form 4562, Part V, for listed property and carry the result over. Keep the supporting records with your return rather than mailing them in.

Vehicle expense deduction FAQ

Can I deduct vehicle expenses if I am self-employed?

Yes. Self-employed people, independent contractors, and gig workers can deduct the business-use portion of their vehicle costs on Schedule C using either the standard mileage rate or actual expenses. This is one of the largest deductions available to drivers who do rideshare, delivery, sales, trades, or any work that puts real business miles on a personal car. If you drive for the apps, see our guide to tax deductions for rideshare drivers for the full write-off list and which miles count.

Can I deduct a car I use for both business and personal driving?

Yes, but only the business share. If 40% of your miles are for business, you deduct 40% of your vehicle costs under the actual expense method, or 40% of your miles times the standard rate. You cannot deduct personal or commuting miles, which is exactly why a mileage log that separates the two is so important. Under the actual expense method you also need the gas, repair, and insurance receipts behind those costs, and the best receipt scanner app for small business keeps them captured as you go instead of reconstructed in April.

Does the standard mileage rate include depreciation?

Yes. The standard mileage rate already includes an amount for depreciation (35 cents of the 72.5-cent 2026 rate), so you cannot claim separate depreciation on top of it. That built-in depreciation reduces your vehicle's tax basis over time, which can create a small taxable gain if you later sell the car for more than its adjusted basis.

Keep your vehicle records audit-ready

Whichever method you choose, the vehicle deduction is only as solid as the records behind it. The standard mileage rate needs a clean mileage log; the actual expense method needs that log plus every fuel, repair, insurance, and registration receipt for the year. The easiest way to stay ready is to capture each receipt as it lands and total the categories at tax time. ReceiptOCR reads the vendor, date, and amount off each slip so your fuel and repair log is built from data, not a glovebox full of faded paper. See how it works for self-employed receipt tracking, for scanning receipts for taxes, or as a year-round receipt tracker for your small business, and use the receipt to Excel converter to total a year of vehicle costs in a spreadsheet.

For the bigger deduction picture, read how to categorize business expenses for taxes, how the business travel expenses deduction handles mileage and per diem, what receipts a small business can deduct, and whether you can deduct expenses without a receipt. Because the actual expense method pulls in a year of fuel, repair, and insurance payments, a bank statement converter lets you pull those charges straight off your card or bank statement, and a bank statement to QuickBooks converter pushes the categorized vehicle costs into your books.
