Is Your Car Lease Payment a Tax Write-Off?

Can you write off a car lease?

Yes! The IRS includes car leases on their list of eligible vehicle tax deductions. If you're a self-employed person or a business owner who drives for work, your lease is fair game.

Many people incorrectly assume that car write-offs only extend to cars that you own, but the IRS has never made that distinction. 

How much of a car lease can you write off?

This is where things get tricky. If you use your car 100% of the time for business purposes, you can take the whole thing. However, most of us don’t have a car that’s exclusively for work. So we have to take some extra steps. 

Finding the business portion of your leased car

The portion of your lease that’s eligible to be written off is what’s called the “business portion.” To determine the business portion, you need to tally up your driving mileage and figure how much was for work and how much was for personal use, like late-night trips to Taco Bell. (I’m kidding, obviously no one gets their munchy fix at Taco Bell — Jack in the Box or bust.)

Point is, figure out the split between your work and personal mileage. From there, divide your business miles by the total mileage for the year.

For example, say you drove 12,000 miles in a tax year, and 8,000 of those were for work:   

• Business mileage: 8,000
• Personal mileage: 4,000
• Total mileage: 12,000

So the business portion of your lease is 66%, because 8,000 ÷ 12,000 = 0.66.

How do I write off my car lease?

There are two basic options for writing off your lease: the actual expense method and the standard mileage rate. 

Using actual expenses

This method is exactly what it sounds like: your actual auto expenses. Remember the calculation we just discussed? You’d multiply that percentage by what you actually paid on your car expenses. 

Your car lease isn’t the only expense you can claim under this method. Other possible write-offs include fuel, insurance, oil changes, and repairs. If you drive for Uber or Lyft, any costs related to making your ride more “passenger-friendly” would qualify. This includes things like air fresheners, car washes, seat covers, and car organizers.

One thing to note: If you’re leasing the vehicle, you can’t claim a depreciation deduction on it. Depreciation is only allowed on vehicles you own. 

Using the standard mileage deduction

Every year the IRS releases a mileage “rate” that is intended to reflect the overall cost of operating a vehicle — the same costs you would claim under the “actual” method, like gas and repairs.

For 2022, the mileage rate is $0.585 per mile from January 1 to June 30. Then it goes up to $0.625 per mile from July 1 to December 31st. (Having two rates is unusual, but it's the IRS's way of dealing with the rising gas prices!)

Calculating your total mileage deduction

To use the example above, let's say your total business mileage for the year is 8,000, — 4,000 from January to June and another 4,000 from July to the end of the year. Your mileage deduction would be $4,840.

That's because 4,000 times $0.585 is $2,340, and 4,000 times $0.625 is $2,500. Add them together, and you get $4,840.

Which method is better?

As a general rule, if you rack up a lot of miles driving for work, the mileage method will probably result in a higher write-off. However, claiming mileage requires you to keep a mileage log to track your business trips throughout the year. If you drive a moderate amount for work, deducting actual expenses will probably save you more.

Be aware that if you use mileage one year on your leased vehicle, you can’t switch to actual costs the next year. You’re locked into whatever method you choose for the entire lease period — including any renewals.

Knowing this, carefully consider which option would be most advantageous to you before deciding.

Deducting sales tax on a car lease 

The sales tax included in your lease payment also counts as business expense. It’s often included in the monthly cost of the lease, and it should be broken out on all your statements.

There are two ways to write off sales tax. 

Writing off your sales taxes as a business expense.

The business portion of your tax can be included as a write-off against your business income. You’ll include it on your Schedule C — under line 9 for “Car and Truck Expenses” — with your other auto expenses.

The same rules apply here as with the lease itself: only the business portion of the tax can be written off. The rest of it can be claimed in your itemized deductions.

Claiming your sales tax as an itemized personal deduction

If you itemize your personal deductions, you can include sales tax on your Schedule A. The IRS even has a nifty sales tax calculator to determine whether your actual sales taxes are higher than the approximate deduction granted automatically.

Bear in mind: If you decide to claim your sales taxes, you can’t claim state income taxes as well. It’s an either-or situation, so you’ll have to figure out which one is higher.

No matter which tax you claim, the overall deduction is limited to $10,000. What does that mean? If you have $12,000 in sales taxes, you’re only allowed to claim $10,000, and the difference can’t be carried over to future years.

So basically, my Aston Martin will have to wait.
