How to Deduct Vehicle Lease Expenses for Business

To deduct vehicle lease expenses for business, you take the business-use portion of what you spend on the car and claim it on your business return using one of two methods: the standard mileage rate, which for 2026 is 72.5 cents per business mile, or the actual expense method, which totals your lease payments and operating costs and multiplies by your business-use percentage.¹ Whichever method you pick in the first year of the lease stays in place for the entire lease term, including renewals.² For higher-value cars, the IRS adds a twist called the lease inclusion amount that shaves the deduction each year.

Sole proprietors claim the deduction on Schedule C (Form 1040); farmers use Schedule F; corporations and partnerships deduct it on their business returns.³ W-2 employees who drive a leased car for work generally cannot deduct it on their personal returns; the unreimbursed employee business expense deduction was eliminated. Your route is reimbursement from your employer under an accountable plan.⁴

Standard Mileage Rate vs. Actual Expenses

The standard mileage rate is the simpler path. Multiply your business miles by 72.5 cents for 2026 and you have your deduction. That rate already includes fuel, insurance, maintenance, registration, and the equivalent of depreciation, so you cannot layer those costs on top. Parking fees and tolls incurred on business trips are deductible separately.¹

The actual expense method tracks every dollar you spend on the car: fuel, oil, tires, repairs, insurance, registration, and the lease payments themselves. Add up the total, then multiply by your business-use percentage.³ The business portion of the lease payments goes on Schedule C, Line 20a.⁵

Which method wins depends on the vehicle and how you drive it. Standard mileage tends to come out ahead for modest cars driven a lot of business miles. Actual expenses tend to win for pricier cars with high lease payments and lower annual mileage. Because you are locked in for the lease term, model both methods across all the years before you sign anything. A three-year mistake is expensive.

Two situations disqualify you from the standard mileage rate entirely: operating five or more vehicles at the same time for business, and having previously claimed accelerated depreciation on the same vehicle.⁶

What Counts as Business Use

Your business-use percentage is business miles divided by total miles driven for the year. It governs the size of your deduction under either method, so getting the numerator right matters.

Business miles include trips between two work locations during the day, drives to meet clients, visits to job sites, and delivery runs. Your regular commute between home and your main workplace does not count, even if you take business calls along the way. If your home qualifies as your principal place of business, though, trips from home to other locations in the same trade are deductible business miles rather than commuting.⁶ That exception can meaningfully lift your business-use percentage.

Keeping Records the IRS Will Accept

The IRS expects contemporaneous records. A mileage log filled in at tax time is the kind of evidence that gets deductions disallowed on audit.

For each business trip, record the date, destination, business purpose, and miles driven. Take odometer readings at the start and end of the tax year to establish total mileage. Electronic tracking apps are fine as long as they capture the required detail and you back the records up. Keep them at least three years after filing.

Hold on to receipts for gas, insurance, repairs, and other operating costs even if you plan to use the standard mileage rate. If actual expenses turn out to produce a larger deduction, or if the IRS questions your return, you will want the paper trail.

The Lease Inclusion Amount

Here is what makes leasing different. If the vehicle’s fair market value on the first day of the lease is high enough, you must reduce your annual deduction by a lease inclusion amount. It applies under both the standard mileage and actual expense methods.²

The rule exists to keep leasing from becoming a workaround for the depreciation caps on purchased cars. A 2026 passenger car purchase is capped at $20,300 of first-year depreciation with bonus, or $12,300 without.⁷ Without the inclusion adjustment, a lessee of a $120,000 sedan could deduct far more than a buyer of the same car.

For leases beginning in 2026, the inclusion amount becomes meaningful once fair market value exceeds roughly $62,000. Below that, the figures are negligible. The specific dollar amounts sit in Table 3 of Rev. Proc. 2026-15.⁷

The calculation runs in three steps each year of the lease:⁶

Look up the dollar amount in the IRS table using the vehicle’s fair market value on the first day of the lease and the applicable year of the lease term. For the final year of the lease, use the prior year’s column.
Prorate that dollar amount by the number of days the vehicle was leased during the tax year. No proration is needed if you leased it all year.
Multiply the prorated amount by your business-use percentage. That result reduces your deduction for the year.

A quick example. You lease a car with a first-day fair market value of $85,000 in 2026. The first-year table amount is $166. You had the car the full year and business use was 80%, so the inclusion amount is $133 ($166 × 0.80). Your lease deduction drops by $133. The table figures rise in later years of the lease, reaching $737 by year five and beyond for that same vehicle.⁷ Sole proprietors show the reduction on Schedule C, and you recalculate it every year the lease is active.⁶

Heavy Vehicles Over 6,000 Pounds

Trucks, vans, and large SUVs with an unloaded gross vehicle weight above 6,000 pounds fall outside the IRS definition of a passenger automobile for depreciation purposes. The luxury car depreciation caps do not apply, and the lease inclusion tables generally do not either.⁶ Lease a qualifying heavy SUV, use actual expenses, and you deduct the business share of the lease payments without the inclusion haircut.

Upfront Fees, Sales Tax, and Deposits

One-time charges at lease signing are not deducted in a single year. Acquisition fees, documentation fees, and any lump-sum cap-cost reduction are treated as prepaid rent and spread evenly across the full lease term.⁸ A $3,600 acquisition fee on a 36-month lease produces a $100 monthly deduction, or $1,200 a year, times your business-use percentage. Report the amortized amount on Form 4562.

Sales tax follows the same logic. Rolled into the monthly payment, it rides along with the regular lease deduction. Paid as a lump sum at signing, it gets amortized over the lease term. States handle this differently: most tax the monthly payment, a few tax the full vehicle price upfront. Either way, only the business share is deductible.

Security deposits are not deductible when paid because they are refundable. If the leasing company keeps some or all of it at lease end for excess wear or other charges, the forfeited amount becomes deductible in the year of forfeiture, prorated for business use.

Early Termination and End-of-Lease Charges

An early termination fee is generally deductible as a business expense in the year you pay it, prorated for business use.⁹ Excess mileage charges and disposition fees at the normal end of the lease work the same way.

If you have been amortizing upfront costs and end the lease before those costs are fully written off, you can generally deduct the remaining unamortized balance in the year of termination. Keep the amortization schedule with the termination paperwork so the numbers are easy to reconstruct.

Two habits protect the deduction more than any planning trick. Keep business use as clean as you can; vehicles that hover near 50% business use produce thin deductions and draw scrutiny. And start the mileage log on day one. Reconstructed records are the weakest evidence you can bring to an audit.
