Using Your Car for Work: Mileage Rate, Actual Expenses, Records

If you drive your personal vehicle for work, whether you can deduct the cost depends almost entirely on how you’re paid. Self-employed workers, independent contractors, and gig drivers can claim car expenses against their business income using either a flat per-mile rate or their actual operating costs. W-2 employees generally cannot claim car expenses for work on their federal return at all, with a few narrow exceptions. The rest comes down to which method saves you more, what counts as business driving, and whether your records will hold up.

Who Can Actually Deduct Car Expenses

If you file a Schedule C as a sole proprietor, independent contractor, or single-member LLC, ordinary and necessary vehicle costs come off your business revenue.¹ That deduction lowers both your income tax and your self-employment tax, because both are calculated on net profit. Rideshare and delivery drivers report the same way.²

W-2 employees have a much worse deal. The Tax Cuts and Jobs Act suspended the deduction for unreimbursed employee business expenses in 2018, and the One, Big, Beautiful Bill Act made that elimination permanent. A few groups can still claim vehicle costs on Form 2106: Armed Forces reservists traveling more than 100 miles from home for reserve duties, qualified performing artists, fee-basis state or local government officials, and employees with impairment-related work expenses.³ Everyone else on a W-2 is shut out federally, even without any reimbursement from their employer. Some states still allow the deduction on the state return, so it’s worth checking your state code.

What Driving Counts as Business Driving

Not every work-related trip qualifies. The IRS separates commuting from business travel, and the line matters.

Commuting is the trip between your home and your regular workplace. It’s never deductible, no matter how far the drive. Business driving includes travel between two work locations, trips to clients or suppliers, driving to a temporary job site, and other business errands.⁴

A qualifying home office changes the calculation. If your home office is your principal place of business, then driving from home to another business location counts as deductible mileage rather than commuting.⁵ For someone whose first stop each day is a client 30 minutes away, that reclassification can shift thousands of miles a year onto the deductible side of the ledger.

The Standard Mileage Rate

The easier of the two methods is the standard mileage rate. Multiply your business miles by the IRS rate for the year. For 2026, that rate is $0.725 per mile.⁶ The rate covers gas, insurance, maintenance, repairs, and depreciation in a single figure. You cannot deduct those items again on top of it. Parking fees and tolls paid on business trips are the only extras you can add.⁷

An example. Drive 18,000 business miles in 2026 and your deduction is $13,050, plus any business parking and tolls.

There’s a timing rule for cars you own. Pick the standard mileage rate in the first year you use the vehicle for business, and you can switch to actual expenses later. Start with actual expenses instead, and you’re locked out of the standard rate for the life of that vehicle. Leased cars are stricter still: whichever method you pick has to stay in place for the entire lease.⁴

Even under the standard rate, depreciation is quietly baked in. The depreciation portion is $0.35 per mile for 2026, and it reduces your car’s tax basis year by year. When you eventually sell or trade the car, that lower basis can produce a taxable gain. Most people never think about this until it hits them.

The Actual Expense Method

The actual expense method means tracking every dollar you spend running the vehicle: fuel, oil changes, tires, insurance premiums, registration, repairs, and the business portion of any loan interest. It’s more work, but it often produces a bigger deduction on expensive cars or vehicles with high operating costs.

The pivot point is your business-use percentage. Divide business miles by total miles for the year. Drive 20,000 miles overall with 15,000 for business, and you’re at 75%. Multiply that percentage by your total vehicle expenses (depreciation aside) to get your deductible amount.⁴

Depreciation is the other piece. It reflects the vehicle’s decline in value, and accelerated first-year write-offs are available through the Section 179 deduction and bonus depreciation. Both get multiplied by the business-use percentage before landing on your return.

Before you commit, run both methods for the vehicle you actually drive. Choosing actual expenses in year one on a car you own permanently blocks the standard mileage rate for that car.

Depreciation Caps and Bonus Depreciation

The IRS caps annual depreciation on passenger vehicles under Section 280F, even if your business-use percentage is 100%. For passenger vehicles placed in service in 2026 with bonus depreciation, the first-year cap is $20,300. Without bonus depreciation, it’s $12,300.⁸

Those caps apply to vehicles under 6,000 pounds gross vehicle weight rating. Heavier vehicles, including full-size work trucks, cargo vans, and larger SUVs above 6,000 pounds GVWR, escape Section 280F and can qualify for much larger first-year write-offs. SUVs between 6,000 and 14,000 pounds GVWR still face a separate Section 179 cap of $32,000, with the remaining cost depreciated over time. Pickups with a bed at least six feet long aren’t subject to that SUV limit.

The One, Big, Beautiful Bill Act restored 100% bonus depreciation for qualifying business property acquired after January 19, 2025.⁹ For passenger cars, though, the Section 280F dollar caps still apply, so even at 100% bonus your first-year deduction on a standard passenger car maxes out at $20,300.⁸ To use Section 179 or bonus depreciation, the vehicle must be used more than 50% for business.

Records That Hold Up If You’re Audited

Whatever number you calculate is only as good as the records behind it. A missing or reconstructed mileage log is the most common reason the IRS throws out vehicle deductions.

For each business trip, your log needs the date, the destination, the business purpose, and the miles driven. The IRS wants these records kept at or near the time of the trip, not assembled later from memory or calendar entries.⁴ A GPS-based mileage app on your phone is the simplest way to meet that standard.

Record your odometer at the start and end of each tax year too. Those numbers give you total miles, the denominator in your business-use percentage.

Using actual expenses means keeping receipts for everything: fuel, insurance, maintenance, repairs, registration. Card and bank statements help, but on their own they’re weaker evidence than most people assume. Save originals or digital copies, organized by year.

If You’re a W-2 Employee: Accountable Plans

Because unreimbursed vehicle expenses aren’t deductible federally for most employees, reimbursement is your only real path to tax relief. The mechanism to ask for is an accountable plan. Under one, reimbursements are tax-free and never appear as W-2 income, provided three conditions are met: the expenses have a business connection, you substantiate them within a reasonable time, and you return any excess.⁴

Many employers reimburse at or near the IRS standard mileage rate, which usually covers costs without creating taxable income. If the plan doesn’t meet the accountable plan requirements, those reimbursements are treated as wages instead.

When You Sell the Vehicle

Selling a car you claimed deductions on has a tax consequence most drivers don’t see coming. Any gain attributable to depreciation you previously claimed, including Section 179 and bonus depreciation, is taxed as ordinary income rather than at capital gains rates.⁴

This applies even if you only ever used the standard mileage rate. The depreciation component inside that rate ($0.35 per mile for 2026) cut your tax basis each year whether you noticed or not. Drive 15,000 business miles a year for four years and your basis is $21,000 lower going into the sale. That makes owing tax on the sale much more likely, even at a sale price below what you originally paid.

Where This Goes on Your Return

Self-employed filers put vehicle deductions on Schedule C. Using the standard rate, multiply business miles by $0.725, add parking and tolls, and enter the total on Line 9.⁷ Complete Part IV of Schedule C, which asks for total miles, business miles, the date the vehicle was placed in service, and whether you have written evidence.

Under the actual expense method, the non-depreciation operating costs (fuel, insurance, repairs) go on Line 9, and depreciation goes on Line 13. Claiming depreciation means filing Form 4562. If you’re using the standard mileage rate and don’t otherwise need Form 4562, the Part IV vehicle information on Schedule C is enough by itself.¹⁰

Schedule C net profit flows to Form 1040 and is subject to both income tax and self-employment tax.¹¹ The few W-2 employees who still qualify report on Form 2106 and carry the result to Schedule 1.³
