You cannot write off the car payment itself when your LLC finances a vehicle, but you can deduct almost everything the payment represents through other means. The IRS treats a vehicle purchase as buying an asset, so the principal portion of each payment is converting cash into property you own rather than spending money. The cost comes back to you through depreciation. The interest portion is deductible as a business expense in the year you pay it, and operating costs like fuel, insurance, and repairs are deductible too, either directly or through the standard mileage rate. Lease payments follow a different rule and are deductible as rent.
Principal, Interest, and Why the Split Matters
A monthly auto loan payment has two parts. The principal pays down the loan balance and builds equity in the vehicle; the IRS does not treat that as an expense because you still have the money, just in the form of an asset. The interest portion is a true cost of borrowing and is deductible in the year paid, multiplied by your business-use percentage.
So when people ask whether an LLC can write off a car payment, the honest answer is that the label on the bill is wrong. You deduct the vehicle, not the payment. And depending on the vehicle and how you use it, the deduction you end up with can be far larger than the sum of the payments you made that year.
The Two Ways an LLC Deducts a Purchased Vehicle
Each year you own and operate a business vehicle, you choose one of two methods: the standard mileage rate or the actual expense method.
Standard Mileage Rate
The standard mileage rate for 2026 is $0.725 per business mile.1Internal Revenue Service. 2026 Standard Mileage Rates Multiply the rate by your business miles for the year and that is your deduction. It covers depreciation, insurance, fuel, maintenance, and repairs in one number. Parking fees and tolls for business trips come off on top.
The catch is timing. You must elect the standard mileage rate in the first year you place the vehicle in service for business.2Internal Revenue Service. Topic No. 510, Business Use of Car Pick actual expenses in year one and you can never switch to the standard rate for that vehicle. The reverse switch is allowed. The rate also carries a built-in depreciation component of $0.26 per mile for 2026, which reduces the vehicle’s basis and matters when you sell.
Actual Expense Method
Under the actual expense method, you add up every operating cost for the year: fuel, oil, tires, repairs, insurance, registration, loan interest, and depreciation. You multiply the total by your business-use percentage (business miles divided by total miles) and deduct the result. This is where loan interest actually lands on your return.
Expensive vehicles and high operating costs usually favor this method. The downside is paperwork; you need receipts for everything you claim.
How Much Depreciation You Can Take in Year One
When your LLC buys the vehicle, depreciation runs on the Modified Accelerated Cost Recovery System (MACRS), the default for business vehicles placed in service after 1986.2Internal Revenue Service. Topic No. 510, Business Use of Car Two accelerated tools, Section 179 expensing and bonus depreciation, can collapse several years of deductions into the first year. How much you actually get depends on the vehicle’s weight.
The 50-Percent Business-Use Gate
Accelerated depreciation requires more than 50% qualified business use in the year the vehicle is placed in service.3Internal Revenue Service. Publication 946 – How To Depreciate Property Fail that test and you lose both Section 179 and bonus depreciation, leaving you with straight-line depreciation over a longer recovery period. If business use later drops to 50% or less, you have to recapture the excess depreciation already claimed and report it as ordinary income.4eCFR. 26 CFR 1.280F-3T – Limitations on Recovery Deductions and the Investment Tax Credit
Passenger Vehicles Under 6,000 Pounds
Most cars, crossovers, and lighter SUVs sit under 6,000 pounds gross vehicle weight rating. Section 280F classifies them as passenger automobiles and caps annual depreciation regardless of what you paid for the car.5Office of the Law Revision Counsel. 26 U.S. Code 280F – Limitation on Depreciation for Luxury Automobiles The nickname “luxury auto limits” is misleading; a modest sedan hits the same ceiling as a sports car.
For passenger vehicles placed in service in 2026 with bonus depreciation applied, the caps are:6Internal Revenue Service. Revenue Procedure 2026-15
- First year: $20,300
- Second year: $19,800
- Third year: $11,900
- Each year after: $7,160
Opt out of bonus depreciation or fail to qualify, and the first-year cap falls to $12,300; later-year caps are unchanged.6Internal Revenue Service. Revenue Procedure 2026-15 All of these amounts are then multiplied by your business-use percentage. A vehicle used 70% for business claims 70% of the cap.
Heavy Vehicles Over 6,000 Pounds
Vehicles above 6,000 pounds GVWR escape the Section 280F caps. That is why so many LLC owners end up in full-size SUVs, pickups, and cargo vans. The rules split into two groups:
- Heavy SUVs over 6,000 pounds but under 14,000 pounds GVWR face a Section 179 deduction cap of $32,000 for 2026, but bonus depreciation has no cap, so any cost above $32,000 can still be written off through bonus depreciation in the same year.
- Heavy trucks and vans, including vehicles with a cargo bed at least six feet long, are not subject to the $32,000 SUV cap and can take the full Section 179 deduction.
A qualifying heavy vehicle used 100% for business can often be deducted in full in year one. A $75,000 heavy-duty pickup can produce a $75,000 first-year deduction. That is simply unavailable for a lighter car capped at $20,300.
100 Percent Bonus Depreciation in 2026
The One, Big, Beautiful Bill permanently restored 100% bonus depreciation for qualified property acquired after January 19, 2025, reversing the phasedown that had cut the rate to 60% in 2024 and 40% in 2025.7Internal Revenue Service. Treasury, IRS Issue Guidance on the Additional First Year Depreciation Deduction Amended as Part of the One, Big, Beautiful Bill For vehicles placed in service in 2026, the full 100% rate applies, though the Section 280F caps still limit lighter passenger vehicles.
If You Lease Instead
Leasing avoids depreciation entirely. Your LLC deducts the business-use percentage of each lease payment as rent. A $600 monthly payment with 80% business use yields $480 a month in deductions. Any upfront payment or capitalized cost reduction must be spread evenly across the lease term, not deducted all at once. Refundable security deposits are not deductible.
The IRS prevents leasing from becoming a workaround for the passenger auto caps through the lease inclusion rule. If the fair market value of a leased passenger vehicle exceeds $62,000 at the start of the lease, you add a small amount to taxable income each year of the lease.6Internal Revenue Service. Revenue Procedure 2026-15 The inclusion amounts are modest but they bring the tax treatment of expensive leases closer to that of purchases.
Which Miles Actually Count
Deductions ride on business miles, and the IRS defines those narrowly. Trips between your home and a regular place of work are commuting, and commuting is never deductible, however long the drive.8Internal Revenue Service. Publication 463 – Travel, Gift, and Car Expenses Taking business calls on the way does not change that.
Deductible miles include driving from your office to a client, between two work sites, on business errands, and to the bank or post office for the business. If a home office is your principal place of business, trips from there to clients or temporary work locations count as business miles instead of commuting. That one distinction often doubles or triples deductible mileage for owners who work from home.
Depreciation Recapture When You Sell
The tax story continues when you dispose of the vehicle. Any gain attributable to depreciation you previously claimed is taxed as ordinary income, not at the lower capital gains rate.9Internal Revenue Service. Publication 544 – Sales and Other Dispositions of Assets Recapture applies to regular MACRS, Section 179, and bonus depreciation alike.
An example: buy a vehicle for $50,000, claim $30,000 in depreciation, then sell it for $25,000. Your adjusted basis is $20,000. The $5,000 gain is taxed as ordinary income because it falls within the $30,000 of depreciation you already took. Recapture equals the lesser of the gain or the total depreciation claimed. The sale is reported on Form 4797.10Internal Revenue Service. About Form 4797, Sales of Business Property
Aggressive first-year write-offs on heavy vehicles need special attention here. A $75,000 deduction in year one feels generous until you sell three years later for $40,000 and pay ordinary income tax on most of the sale price. The deduction is a timing benefit, not a free one.
Records That Keep the Deduction
No vehicle deduction holds up without records. The IRS wants contemporaneous documentation, meaning you log trips and save receipts as they happen rather than reconstructing them months later.8Internal Revenue Service. Publication 463 – Travel, Gift, and Car Expenses
Each business trip entry needs the date, starting point and destination, business purpose, miles driven, and odometer readings at the start and end of the tax year. Per-trip odometer readings are not required, but year-end readings are, as are readings at the beginning and end of any period of business use. GPS-based mileage apps meet these requirements and are more reliable than a notebook.
If you use the actual expense method, keep receipts for every cost you claim, including the interest portion of loan statements. The burden of proof is yours. Inadequate records can result in complete disallowance of vehicle deductions plus accuracy-related penalties.11Internal Revenue Service.
