Buying a car generally offers better long-term tax write-offs through depreciation and interest deductions, especially with bonus depreciation. Leasing provides higher, simpler deductions on monthly payments for newer cars, but lacks equity and depreciation benefits. Buying is better for long-term ownership, while leasing is advantageous for frequent upgrades.
Leasing can offer appealing tax advantages for those using their vehicle for business, as lease payments may be deductible. Meanwhile, buying a car allows owners to deduct depreciation and, in some cases, loan interest from their income, making it a more beneficial long-term option for certain taxpayers.
If you lease a vehicle and use it solely for business purposes, you can generally deduct the full amount of your lease payments. This means you can write off every monthly payment you make towards your lease as a business expense, reducing your overall taxable income, which could reduce your taxes.
The "1% lease rule" is a guideline in both real estate (rental income should be 1% of property cost) and auto leasing (monthly payment ideally under 1% of MSRP), used for quickly assessing potential deals, though it's a simplified benchmark that doesn't account for all expenses or market variations. In car leasing, a $40,000 car should ideally lease for around $400/month (before tax), while for real estate, a $200,000 home should aim for $2,000/month in rent.
The IRS permits you to write off the portion of your monthly lease payment that corresponds to business use. For example, if you use the vehicle 75% for work, you can deduct 75% of your lease payments. In 2024, the IRS also limits the amount you can deduct based on the vehicle's value and business use percentage.
The main disadvantage of leasing a vehicle is that you never own it, meaning you build no equity and have no asset at the end of the term, essentially paying for a long-term rental with potential extra costs like mileage overages, wear-and-tear fees, and early termination penalties, leading to continuous payments if you keep leasing.
The 90% rule in leasing is an accounting guideline for classifying leases, stating that if the present value (PV) of a lessee's minimum lease payments equals or exceeds 90% of the leased asset's fair market value (FMV), the lease should be treated as a finance lease (or capital lease) rather than an operating lease, reflecting essentially a purchase for accounting purposes. This rule helps determine if the lease transfers substantially all the risks and rewards of ownership, requiring balance sheet recognition of the asset and liability.
In summary, the benefits of leasing a car through your company:
Yes, you can write off 100% of a vehicle's cost in the first year for business use, but it generally requires the vehicle to be a heavy-duty truck, van, or SUV (over 6,000 lbs Gross Vehicle Weight Rating or GVWR) and used exclusively for business, leveraging Section 179 deduction and bonus depreciation. Lighter passenger vehicles have strict caps, even if used 100% for business, with maximum first-year depreciation limits (around $20,200 for 2025).
Best Option for company cars – self employed? ✅ For sole traders – Buying a car personally and claiming mileage is usually simpler and more tax-efficient unless it's an electric car. ✅ For limited companies – An electric company car can be tax-efficient, but petrol/diesel cars often trigger high BiK taxes.

Banks and building societies differ in their lending criteria. Some draw the line at 75 years remaining on the lease; others may be happy with anything over 70 years. Below 60 years, it may be difficult to get a mortgage at all. However there are ways to overcome the “short lease” problem.
For most situations, if the lease term exceeds 75% of the remaining economic life of an asset and the asset still has at least 25% of its original useful life left, then the lease is considered a finance lease.
Three main disadvantages of leasing a car are mileage restrictions leading to extra fees, no ownership equity built up, and penalties for excess wear and tear or early termination, meaning you don't own the asset and can face significant extra costs if you go over limits or end the contract early.
If you lease a vehicle, you can deduct the sales tax that is applied to your monthly payments. Operating expenses. You can deduct business expenses for operating and maintaining your vehicle, including fuel, oil changes, and repairs. These deductions are available if you use the actual expense method to calculate.
Because lease payments are a lot less than car loan payments, many people use the difference to drive a more upscale luxury model that they might not be able to afford to purchase.
The new car loan interest tax deduction (also sometimes called no tax on car loan interest) lets taxpayers deduct up to $10,000 per taxable year for interest paid on a qualifying vehicle loan. This deduction is below-the-line, meaning it reduces your taxable income, but does not reduce your adjusted gross income (AGI).
Cars qualify for tax write-offs if used for business, with different rules for light vehicles (under 6,000 lbs GVWR) and heavy vehicles (over 6,000 lbs), using deductions like Section 179, which allows significant write-offs for heavier SUVs, trucks, and vans, or the new "One Big Beautiful Bill" (OBBB) deduction for personal, U.S.-assembled vehicles' loan interest, with specifics on weight, assembly, and business use being crucial for eligibility.
There are several advantages to buying a car for business under an LLC, such as liability protection, tax deductions, and extra privacy.
