To write off a car lease with an LLC, you figure out what share of the vehicle’s use is for business, then deduct that share of the costs using one of two IRS-approved methods: the actual expense method or the standard mileage rate. Whichever method you pick in the first year the LLC uses the leased vehicle for business, you must stick with for the full lease term, including renewals.1Internal Revenue Service. Rev Proc 2019-46 – Standard Mileage Rates For 2026, the standard rate is 72.5 cents per business mile, and the lease inclusion rule starts biting on vehicles worth more than $62,000 at the start of the lease.2Internal Revenue Service. Notice 2026-10 – 2026 Standard Mileage Rates
Start With Your Business Use Percentage
Every number in this process rests on one calculation: business miles divided by total miles. Drive 20,000 miles in a year with 14,000 of them for business, and your business use percentage is 70%. That ratio is what the LLC applies to lease payments, fuel, insurance, and everything else under the actual expense method, and it’s what the IRS wants to see on Form 4562 regardless of which method you use.
What counts as a business mile is narrower than most owners assume. Commuting from your home to a regular workplace is personal, always, no matter what you do during the drive. Trips from your office to a client, between two business locations, or out to pick up supplies are business miles. If you have a qualifying home office, your home is your 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
Pick a Method Before You File the First Return
The method choice is a one-shot decision for the life of the lease. There’s no switching to the other method next year because it turns out to pay better. For a vehicle you own, the rules give you some flexibility; for a lease, they don’t.1Internal Revenue Service. Rev Proc 2019-46 – Standard Mileage Rates
Neither method is universally better. Actual expenses usually win when the vehicle is relatively expensive, business mileage is low to moderate, or operating costs run high (premium fuel, urban insurance, aging vehicle needing repairs). The standard mileage rate usually wins when the car is modest and business miles are high relative to total driving. Project both methods across the full lease term before deciding, not just year one, because mileage patterns and maintenance costs shift as the lease ages.
The Actual Expense Method
Under this method, the LLC deducts the business-use percentage of every cost tied to running the leased vehicle: lease payments, fuel, oil, repairs, tires, insurance, and registration. If business use is 70%, you deduct 70% of each line.4Office of the Law Revision Counsel. 26 US Code 162 – Trade or Business Expenses
The monthly lease payment is usually the biggest piece, but a separate rule chips at it when the vehicle is pricey. Under Section 280F, if the fair market value of a leased passenger vehicle exceeds $62,000 at the start of a lease beginning in 2026, you must add a small “lease inclusion amount” to gross income each year of the lease.5Internal Revenue Service. Rev Proc 2026-15 – Limitations on Depreciation Deductions for Passenger Automobiles That addition effectively reduces your net deduction. The dollar figure comes from Table 3 of Rev. Proc. 2026-15 and depends on the vehicle’s value and which year of the lease you’re in. If your leased vehicle sits below $62,000, you can ignore the rule entirely.6Office of the Law Revision Counsel. 26 USC 280F – Limitation on Depreciation for Luxury Automobiles
The Standard Mileage Rate
Simpler math. Multiply documented business miles by the IRS rate: 72.5 cents per mile for 2026.7Internal Revenue Service. IRS Sets 2026 Business Standard Mileage Rate at 72.5 Cents Per Mile An LLC with 15,000 business miles deducts $10,875.
The rate is built to cover both variable costs (gas, maintenance) and fixed costs (insurance, the lease payment itself). Because the lease payment is already baked in, you cannot deduct the monthly lease on top. The one carve-out: business-related parking fees and tolls aren’t included in the per-mile figure, so they stay separately deductible.8Internal Revenue Service. Topic No 510 Business Use of Car
A full mileage log is still required under this method. Without it, you have no verified business miles, and the deduction collapses.
Records the IRS Will Accept
The IRS requires substantiation kept at or near the time of each trip. A log reconstructed from calendar entries at tax time carries far less weight than one maintained weekly. A log that accounts for each trip during the week is considered timely.3Internal Revenue Service. Publication 463 – Travel, Gift, and Car Expenses
Each entry should capture the date, destination, business purpose, and mileage. GPS-based mileage apps satisfy the contemporaneous standard as long as you confirm the business purpose for each trip.
Beyond mileage, keep receipts for fuel, maintenance, insurance, and monthly lease payments. Pay all vehicle costs from the LLC’s bank account rather than a personal one. That single habit does more to protect the deduction in an audit than any software subscription.
If Your Records Fall Short
This is where most vehicle deductions die. If the IRS audits and you can’t produce a contemporaneous log with dates, destinations, purposes, and mileage, the deduction is disallowed or cut to whatever the auditor considers reasonable. There is no partial credit for having tried.
A disallowed deduction creates an underpayment. On top of the extra tax, the IRS can add an accuracy-related penalty of 20% of the underpayment when it stems from negligence or disregard of the rules.9Office of the Law Revision Counsel. 26 US Code 6662 – Imposition of Accuracy-Related Penalty on Underpayments Interest accrues from the original due date. On a $10,000 deduction that gets thrown out, the combined cost of back tax, penalty, and interest can exceed what the deduction saved.
Where the Deduction Goes on the Return
How the LLC reports vehicle expenses depends on its tax classification, not its legal form. The LLC itself is a legal wrapper; the IRS treats it as a disregarded entity, a partnership, or a corporation depending on membership and elections.
Single-Member LLC
A single-member LLC without a corporate election is a disregarded entity, and everything flows to Schedule C on your personal 1040. Standard mileage rate deductions (business miles times the rate, plus parking and tolls) go on Line 9. Under the actual expense method, operating costs like gas, oil, repairs, and insurance go on Line 9, while lease payments go on Line 20a, reduced by any lease inclusion amount.10Internal Revenue Service. Instructions for Schedule C Form 1040
Multi-Member LLC
A multi-member LLC defaults to partnership treatment and files Form 1065, passing profits and losses to members on Schedule K-1.11Internal Revenue Service. Partnerships Vehicle lease payments go on Line 13 (Rent). If the lease runs 30 days or more, the deduction is reduced by the lease inclusion amount.12Internal Revenue Service. 2025 Instructions for Form 1065
LLC Taxed as an S-Corporation
An LLC that has elected S-corp treatment with Form 2553 files Form 1120-S and deducts 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, and any personal use is reported as a taxable fringe benefit on the employee’s W-2. The alternative is for the shareholder to lease personally and have the S-corp reimburse business mileage through an accountable plan, which avoids fringe benefit payroll work but caps the deduction at the standard mileage rate.
Form 4562 in Every Case
Regardless of classification, attach Form 4562 when claiming vehicle expenses. Part V covers listed property, including passenger vehicles, and asks for total miles, business miles, the business-use percentage, and whether you have written evidence to back the numbers.13Internal Revenue Service. About Form 4562 Depreciation and Amortization The requirement applies even though a leased vehicle isn’t depreciated.
Personal Use by an Owner or Employee
If the LLC leases a vehicle and an employee (an owner treated as an employee counts) uses it personally, the value of that personal use is taxable compensation. The LLC calculates the fringe benefit value, adds it to the employee’s W-2, and withholds. The IRS allows three valuation methods, and whichever one the LLC picks for a vehicle must be used consistently in later years:14Internal Revenue Service. Publication 15-B Employers Tax Guide to Fringe Benefits
- The cents-per-mile rule, which multiplies the standard mileage rate by personal miles and requires the vehicle’s value to fall below an annual cap.
- The annual lease value rule, which uses an IRS table based on fair market value, multiplied by the personal-use percentage.
- The commuting rule, which values each one-way commute at $1.50 and only applies when the LLC has a written policy barring other personal use and actually enforces it.
Skipping this step doesn’t just create a payroll problem. If an auditor spots personal miles that were never accounted for, the underlying lease deduction itself can come under question.
