Are Company Cars Tax Deductible? Methods, Limits, and Records

Yes, company cars are tax deductible, but only for the portion tied to business use and only for the person or entity that actually owns or leases the vehicle. Business owners — sole proprietors, partnerships, S-corporations, and C-corporations — can deduct the ordinary and necessary costs of a car used in the business.¹ You can either claim a flat 72.5 cents for every business mile you drive in 2026, or you can add up your actual expenses (fuel, insurance, repairs, depreciation, lease payments) and deduct the business-use share.²

Who Gets to Deduct the Car

The deduction belongs to whoever holds the title or pays the lease. A corporation that owns the vehicle claims it as a corporate expense. A sole proprietor claims it on Schedule C of Form 1040.³ If you drive a personally owned car for business tasks — visiting clients, running to a job site — you can still deduct the business share of those costs even though it isn’t a “company car” in the traditional sense.

Most W-2 employees cannot deduct anything. Federal law eliminated the write-off for unreimbursed employee business expenses, so a salaried worker who uses a personal car for work errands gets no federal deduction for those miles.⁴ Only three narrow groups can still file Form 2106 for vehicle expenses: Armed Forces reservists, qualified performing artists, and fee-basis state or local government officials. If your employer expects you to drive for work, the practical fix is a reimbursement arrangement with the employer, not a personal deduction.

What Driving Actually Counts

Only the business portion of your driving is deductible, and the IRS is strict about what qualifies. Driving from home to your regular office is commuting. Commuting is personal, no matter the distance, and it’s never deductible.⁵

Trips that do qualify include:

Travel between worksites during the workday
Visits to clients, customers, vendors, or job sites
Travel to business meetings and conferences away from your regular workplace
Trips from home to a temporary work location, if the assignment is realistically expected to last one year or less⁶

If your home qualifies as your principal place of business — you have a dedicated home office — then trips from home to any other work location in the same trade count as business miles.⁴ When one car serves both personal and business needs, you need to track miles carefully so only the business percentage gets deducted.

Standard Mileage or Actual Expenses

You choose one of two methods each year, but the choice you make in the first year the vehicle is available for business use limits your options later.

The Standard Mileage Rate

The IRS sets a flat per-mile rate that already accounts for gas, depreciation, insurance, and wear. For 2026 the rate is 72.5 cents per business mile.² Multiply your business miles by the rate and add any tolls and parking on top. Tolls and business parking are deductible separately regardless of which method you use.⁵

To use this method, you have to elect it the first year the vehicle is available for business use. For an owned car, choosing the standard rate counts as electing out of accelerated depreciation, so if you switch to actual expenses in a later year you’re stuck with straight-line depreciation for the rest of the vehicle’s useful life.⁷ For a leased car, if you start with the standard rate you have to stay with it for the entire lease, renewals included.

The Actual Expense Method

Under this method you add up every deductible operating cost for the year and multiply by your business-use percentage. Qualifying costs include:⁵

Gas and oil
Repairs, maintenance, and tires
Insurance premiums
Registration and license fees
Lease payments
Depreciation on a vehicle you own
Garage rent

If your yearly costs total $15,000 and the car is used 75% for business, your deduction is $11,250. This method usually beats the standard rate for expensive vehicles or cars with heavy maintenance costs.

Depreciation Limits on an Owned Car

When you own a business vehicle and use the actual expense method, depreciation is normally the largest single deduction. The IRS caps how much passenger-vehicle depreciation you can claim each year under Section 280F.⁸ For vehicles placed in service in 2025 (the most recent limits the IRS has published), the caps are:⁹

First year without bonus depreciation: $12,200
First year with bonus depreciation: $20,200
Second year: $19,600
Third year: $11,800
Each year after that: $7,060

The 2026 figures had not yet been published at the time of writing. The amounts usually shift only modestly from year to year, so expect numbers close to those above.

Bonus Depreciation and Section 179

Bonus depreciation lets you claim an extra first-year deduction on new and used qualifying vehicles. Recent legislation restored 100% bonus depreciation for property placed in service in 2026. For passenger vehicles the Section 280F caps still apply, so the practical benefit shows up as the higher first-year limit above.

Section 179 lets you deduct the full cost of qualifying business equipment in the year of purchase instead of spreading it out. The overall 2026 Section 179 limit is roughly $2,560,000. For SUVs, crossovers, and similar vehicles rated between 6,000 and 14,000 pounds gross vehicle weight, the Section 179 deduction is capped at about $32,000.¹⁰ Heavy trucks and vans above 14,000 pounds, along with pickup trucks that have a bed at least six feet long, aren’t subject to that sub-limit and can qualify for the full Section 179 amount. Vehicles under 6,000 pounds remain subject to the 280F caps even when you elect Section 179.

The 50% Business Use Rule

To claim Section 179 or bonus depreciation on any vehicle, you have to use it more than 50% for business in the year you place it in service.¹¹ At 50% or below you can’t use Section 179 at all, and you’re limited to straight-line depreciation over a longer recovery period.

If business use later drops to 50% or less during the recovery period, the IRS requires depreciation recapture: you add back to income the difference between what you actually deducted and what straight-line depreciation would have produced.⁵ Recapture gets reported on Form 4797, and from that point you switch to straight-line for the rest of the recovery period. That risk is worth thinking about before claiming aggressive first-year deductions on a car whose use might drift personal over time.

When an Employee Drives the Company Car

If a business provides a vehicle and an employee uses it for personal driving, the value of that personal use is a taxable fringe benefit. The employer has to include it as compensation on the employee’s W-2 and withhold payroll taxes. The IRS allows three valuation methods: an annual lease value based on IRS tables, a cents-per-mile method available in 2026 only for vehicles worth $61,700 or less when first made available,¹² or a commuting valuation of $1.50 per one-way trip when the employer restricts the vehicle to commuting only.¹³ The commuting method isn’t available for control employees — generally officers earning $145,000 or more, directors, or employees earning $290,000 or more.

Records the IRS Expects

You need a contemporaneous log, meaning one made at or near the time of each trip. Substantiation rules require you to record the mileage, date, destination, and business purpose of each business trip.¹⁴ Keep receipts for any expense of $75 or more and for all lodging costs. If you use actual expenses, hold receipts for fuel, insurance, repairs, and everything else you plan to deduct. The standard mileage rate simplifies the arithmetic, not the recordkeeping — you still need the mileage log.

Bad records don’t just shrink the deduction. If the IRS audits and you can’t substantiate the expenses, the whole deduction can be disallowed, and negligence or a substantial understatement can add a 20% accuracy-related penalty on top of the unpaid tax.¹⁵ A smartphone app that logs trips automatically is one of the cleanest ways to produce the kind of record the IRS accepts.

Where the Deduction Goes on Your Return

The right form depends on how the business is organized:

Sole proprietors report vehicle expenses on Schedule C (Form 1040).¹⁶
Depreciation, Section 179, and bonus depreciation go on Form 4562, which is also where you report business-use percentage for listed property.¹⁰
The narrow group of employees still eligible files Form 2106.¹⁷
Recaptured depreciation gets reported on Form 4797.

Partnerships and S-corporations report vehicle expenses on Form 1065 or Form 1120-S, and the deductions flow through to owners on Schedule K-1. C-corporations deduct vehicle costs on Form 1120. The underlying substantiation — mileage log, receipts, business-use percentage — is the same no matter which entity files the return.
