Buy or lease a business vehicle: the tax differences
There is no single best answer. Taxes are only one part of the decision, but they change the numbers more than most people expect. Here is how each choice is deducted.
Prepared by Prem Tax and Accounting Corp. Last checked against official sources on October 20, 2026.
Side by side
| Buy | Lease | |
|---|---|---|
| What you deduct | Depreciation on the business share of the cost, plus the business share of running costs and loan interest. Or the mileage rate. | The business share of each lease payment, plus running costs. Or the mileage rate, with the lease rule below. |
| Yearly dollar caps | Yes for a car of 6,000 pounds or less: $20,300 in the first year with bonus depreciation (2026). Heavier vehicles are not capped this way. | A small "inclusion amount" reduces the deduction, but only if the vehicle was worth more than $62,000 when the lease began. |
| A fast write-off? | Possible for heavier vehicles: 100% bonus depreciation and Section 179 (with a $32,000 cap on most SUVs). | No. You deduct payments as you make them. |
| Business use over 50%? | Needed for bonus depreciation and Section 179. If it later drops to 50% or less, some of the deduction is taken back. | No such test, but you deduct only the business share. |
| Cash at the start | A down payment or the full price, plus sales or use tax. | Often less up front. |
| When you stop using it | You own it. Selling a vehicle you have depreciated can create taxable gain, and part of it is taxed as ordinary income. | You return it. No gain or loss to report, but there can be end-of-lease charges for extra miles and wear. |
| Mileage and wear | No limit, but heavy use lowers resale value. | The contract sets a mileage allowance and charges for extra miles and damage. |
| Standard mileage rate | Allowed if you choose it in the first year the vehicle is available for business use. | Allowed, but if you choose it you must use it for the whole lease period, including renewals. |
Questions that usually decide it
- How many miles a year? Heavy driving is costly under a lease mileage allowance.
- How long will you keep it? Long ownership tends to favor buying. Replacing every few years often favors leasing.
- What does it weigh? A vehicle rated over 6,000 pounds can be written off much faster when bought. See depreciation and Section 179.
- How much business use? At 50% or less you lose the fast write-offs on a purchase.
- What is it worth? A vehicle worth more than $62,000 on the first day of a 2026 lease triggers the inclusion amount.
- Which mileage method? The first-year choice affects both. See mileage or actual costs.
A worked example (numbers made up)
A consultant uses a $70,000 vehicle 80% for business. The numbers below are made up to show how the rules work. They are not advice for any person, and they leave out running costs, loan interest, sales tax and your own tax rate.
| Buy: car of 6,000 pounds or less | Buy: truck or SUV over 6,000 pounds | Lease: $1,000 a month from March 1, 2026 | |
|---|---|---|---|
| Business share | 80%, so $56,000 of the cost | 80%, so $56,000 of the cost | 80% of each payment |
| Year 1 deduction | $16,240: the cap of $20,300 times 80% | $56,000 with 100% bonus depreciation, if it qualifies | $7,973: ten payments times 80%, less a $27 inclusion amount |
| Year 2 deduction | $15,840: the cap of $19,800 times 80% | Nothing more for the cost. Running costs continue. | $9,531: twelve payments times 80%, less a $69 inclusion amount |
| The catch | The caps spread the cost over about 6 years ($11,900 and then $7,160 a year, times 80%, in later years) | The cost is recovered in year 1. Selling later can create taxable gain. | The inclusion amount is small at this value |
Taxes are one factor. Compare the cash cost of each choice as well, and ask us to run your own numbers.
Do not mix up a lease and a purchase
The IRS says you cannot deduct payments you make to buy a vehicle, even if the contract calls them lease payments. If a "lease" ends with you owning the vehicle, read the contract or ask us before you deduct the payments as rent.
Common questions
Is it better to lease or buy for taxes?
Neither always wins. A heavy vehicle that qualifies for bonus depreciation or Section 179 can give a large first-year deduction when you buy it. A lease spreads the deduction over the payments. Cash flow, mileage, how long you keep the vehicle and its weight usually matter more than the label. For your own numbers, ask us before you sign.
Can I deduct the whole lease payment?
Only the business share. If you use the vehicle 80% for business, you deduct 80% of each payment. If the vehicle was worth more than $62,000 on the first day of a lease that starts in 2026, a small inclusion amount reduces the deduction.
Can I use the standard mileage rate on a leased vehicle?
Yes, but if you choose it you must use it for the whole lease, including renewals, and you cannot deduct the lease payments.
Does putting the vehicle in my business name change the deduction?
Not by itself. What matters is how much of the use is for business and whether you can prove it. For an S corporation or a partnership, who owns the vehicle affects how it is reported, so plan it before you buy.
Can I deduct sales tax and registration?
Sales tax on a purchase becomes part of the cost, which you recover through depreciation. With actual costs, the business share of registration and similar fees is deductible. With the mileage rate, those costs are already in the rate, except business parking and tolls.
