To write off a car lease with an LLC, figure out what share of the vehicle’s miles are for business, then deduct that share of your costs using one of two IRS-approved methods: the actual expense method or the standard mileage rate. The method you pick in the first year the LLC uses the leased vehicle for business is locked in for the entire lease, including renewals, so the decision matters more than it does for a vehicle you own.1Internal Revenue Service. Rev Proc 2019-46 – Standard Mileage Rates For 2026, the standard mileage rate is 72.5 cents per business mile.2Internal Revenue Service. Notice 2026-10 – 2026 Standard Mileage Rates
Start With Your Business Use Percentage
Every vehicle deduction rests on one number: business miles divided by total miles for the year. Drive 20,000 miles with 14,000 for business and your business use percentage is 70%. That ratio drives everything that follows.
The line between business and personal driving is sharper than most people expect. Commuting from home to a regular workplace is personal, always, no matter how long the drive. Trips from your office to a client, between two business locations, or out for supplies count as business. If you have a qualifying home office, your home becomes the principal place of business and trips from there to other work locations in the same trade become deductible.3Internal Revenue Service. Publication 463 – Travel, Gift, and Car Expenses
Choose a Method: Actual Expenses or Standard Mileage
Actual Expense Method
Under actual expenses, the LLC deducts the business-use percentage of every cost tied to operating the leased vehicle: monthly lease payments, fuel, oil changes, repairs, tires, insurance, and registration.4Office of the Law Revision Counsel. 26 US Code 162 – Trade or Business Expenses With a 70% business use figure, you deduct 70% of each.
The lease payment is usually the largest line, but a special rule shrinks the deduction when the leased vehicle is expensive. It’s called the lease inclusion amount, and it exists because buyers of luxury vehicles face annual depreciation caps under Section 280F. Without it, leasing an expensive car would beat buying one on taxes, and the IRS doesn’t allow that gap.5Office of the Law Revision Counsel. 26 USC 280F – Limitation on Depreciation for Luxury Automobiles
For leases beginning in 2026, the inclusion amount applies to passenger vehicles with a fair market value above $62,000 at the start of the lease. Below that, ignore the rule. Above it, look up a dollar amount in Table 3 of Rev. Proc. 2026-15 based on fair market value and the year of the lease. That figure gets added to gross income, which effectively reduces the net deduction. Amounts are modest near the threshold and grow with the vehicle’s price.6Internal Revenue Service. Rev Proc 2026-15 – Limitations on Depreciation Deductions for Passenger Automobiles
Standard Mileage Rate
The mileage method is simpler. Multiply documented business miles by the IRS rate — 72.5 cents for 2026.7Internal Revenue Service. IRS Sets 2026 Business Standard Mileage Rate at 72.5 Cents Per Mile Log 15,000 business miles and the deduction is $10,875.
That rate already covers fuel, maintenance, insurance, and the lease payment itself. You cannot deduct actual lease payments on top of it. Business parking and tolls are the exception; those stay separately deductible.8Internal Revenue Service. Topic No 510 Business Use of Car You still need a complete mileage log; without one, there are no verified business miles and the deduction collapses.
The Lock-In and How to Decide
Whichever method the LLC picks in the first year the vehicle is used for business, it applies for the whole lease and any renewals. Switching is not allowed for a leased vehicle, which is a stricter rule than the one for vehicles you own.1Internal Revenue Service. Rev Proc 2019-46 – Standard Mileage Rates
Actual expenses tend to produce larger deductions when the vehicle is relatively expensive, total miles are lower, or operating costs run high. The mileage rate tends to win when the vehicle is modest and business mileage is high. Project both methods across the full lease term, not just year one, before you file the first return.
Keep Records the IRS Will Accept
Vehicle expenses have to be substantiated with records kept at or near the time of each trip. A log built from memory at tax time carries far less weight than one kept weekly. The IRS treats a weekly log covering each trip in that week as timely.3Internal Revenue Service. Publication 463 – Travel, Gift, and Car Expenses
Each entry needs four things:
- The date of the trip.
- The destination.
- The business purpose (client meeting, supply pickup, delivery).
- The miles driven.
Beyond the log, keep receipts for every vehicle-related cost: fuel, maintenance, insurance, and lease payments. These support the actual expense method and prove that the LLC, not you personally, paid the costs. Run everything through the LLC’s bank account. GPS mileage apps satisfy the contemporaneous-record standard as long as you confirm each trip’s business purpose.
Where the Deduction Goes on the Return
How the LLC is taxed decides which form the deduction lands on. The LLC is a legal structure, not a tax classification, and the IRS treats it differently depending on member count and any elections filed.
Single-Member LLC
A single-member LLC that hasn’t elected corporate treatment is a disregarded entity. Income and expenses flow to Schedule C on Form 1040. Standard mileage totals (business miles times the rate, plus business parking and tolls) go on Line 9. Under actual expenses, operating costs like gas, oil, repairs, and insurance go on Line 9, and lease payments go on Line 20a, reduced by any lease inclusion amount.9Internal Revenue Service. Instructions for Schedule C Form 1040
Multi-Member LLC
A multi-member LLC is typically taxed as a partnership and files Form 1065. The partnership itself doesn’t pay income tax; profits and losses pass through to members on Schedule K-1.10Internal Revenue Service. Partnerships Lease payments go on Line 13 (Rent) of Form 1065. If the lease runs 30 days or more, reduce the deduction by the lease inclusion amount.11Internal Revenue Service. 2025 Instructions for Form 1065
LLC Taxed as an S-Corporation
An LLC that has elected S-corp treatment by filing Form 2553 files Form 1120-S and can deduct vehicle lease expenses at the entity level. If the LLC leases the vehicle in the company’s name and an employee-shareholder drives it, the company deducts the business-use portion of lease payments and operating costs. Personal use by the employee-shareholder has to be reported as taxable fringe benefit income on the W-2. An alternative: the employee-shareholder leases personally, and the S-corp reimburses business mileage through an accountable plan. That avoids the fringe benefit issue but limits the deduction to the standard mileage rate.
Form 4562 Every Time
Regardless of tax classification, Form 4562 attaches to the return when claiming vehicle expenses. Part V covers listed property, including passenger vehicles. You report total miles, business miles, the business-use percentage, and whether you have written evidence supporting the numbers.12Internal Revenue Service. About Form 4562 Depreciation and Amortization The requirement applies even though a leased vehicle isn’t being depreciated; the IRS uses Form 4562 to verify the business-use claim behind any vehicle deduction.
Personal Use by an Owner or Employee
When the LLC leases a vehicle and an employee (including an owner treated as an employee) uses it for personal driving, that personal use is taxable compensation. The LLC calculates the fringe benefit value, reports it on the W-2, and withholds taxes. The IRS offers three valuation options — the cents-per-mile rule, the annual lease value rule, and the commuting rule at $1.50 per one-way trip — each with its own eligibility conditions.13Internal Revenue Service. Publication 15-B Employers Tax Guide to Fringe Benefits Whichever the LLC picks for a given vehicle, it has to use that method consistently in later years. Skipping this step doesn’t just create a payroll problem; personal miles the LLC never accounted for can undermine the underlying lease deduction if the IRS looks.
What Happens if the Records Fall Short
Sloppy documentation is where most vehicle deductions die. Without a contemporaneous log showing dates, destinations, purposes, and miles for each trip, the deduction gets disallowed or cut to whatever the auditor considers reasonable. There’s no partial credit for good intentions.
A disallowed deduction means underpaid tax. On top of the back tax, the IRS can add a 20% accuracy-related penalty if the underpayment came from negligence or careless disregard of the rules.14Office of the Law Revision Counsel. 26 US Code 6662 – Imposition of Accuracy-Related Penalty on Underpayments Interest runs from the original due date. For a $10,000 vehicle deduction that gets thrown out, the combined bill can easily exceed the deduction itself.
One Boundary Worth Knowing
The Commercial Clean Vehicle Credit under Section 45W, which offered up to $7,500 for qualifying electric or plug-in hybrid vehicles under 14,000 pounds, expired for vehicles acquired after September 30, 2025. New leases signed in 2026 cannot claim it.15Internal Revenue Service. Commercial Clean Vehicle Credit The lease deduction itself is unaffected.
