Do you pay taxes when you sell a junk car?

For most people, junking or selling an old personal car creates no federal income tax and nothing to deduct. Here’s why, and the few cases where it’s different.

The rule for personal-use cars

The IRS treats almost everything you own for personal use as a capital asset, and a car you drive for personal use is one.¹ Publication 544 puts it this way: gain from selling personal-use property is a capital gain, and a loss from selling it is not deductible.² IRS Topic 409 names cars specifically: losses from the sale of personal-use property, “such as your home or car,” aren’t tax deductible.¹

That gives two outcomes:

You sold the car for…	Tax result
Less than your basis (the usual case for a junk car)	Loss. No tax owed, and the loss can’t be deducted
More than your basis	Gain. Taxable as a capital gain

How to work out gain or loss

Gain or loss = amount realized − adjusted basis

• Amount realized is the total of all the money you receive from the sale, plus the value of any property or services.² For a junk car, that’s usually the cash the buyer pays.
• Basis is usually what you paid for the car.²
• Adjusted basis is that cost increased by certain additions, such as improvements, and reduced by certain deductions, such as depreciation and casualty losses.²

Example with placeholders: you bought the car for C and sell it as junk for S. If S is less than C, you have a nondeductible loss and nothing to pay. Since junk cars usually sell for a fraction of what their owners paid, that’s the normal result.

When a gain can happen

A gain on a junk car is unusual, but possible, for example:

• You bought the car very cheaply, or as a non-running project, and sold it for more.
• It’s a collectible or classic model that has gone up in value.
• You received it in a way that gives it a low basis. Inherited and gifted property have their own basis rules. See selling an inherited car and check IRS Publication 551 or a tax professional.

If you have a gain, it’s long-term if you held the car more than a year and short-term if you held it a year or less.¹ The IRS says gains on personal items are reported on Form 8949 and Schedule D.³

If you get a Form 1099-K

Payment apps and online marketplaces may send a Form 1099-K if your payments are over the reporting threshold. The IRS currently describes that threshold as more than $20,000 in gross payments and more than 200 transactions, after the One Big Beautiful Bill reinstated the earlier threshold.³ One junk car sale won’t usually reach it, but if you do receive a 1099-K that includes a car sold at a loss:

• The IRS says “the loss on the sale of a personal item is not deductible,” and explains how to report the 1099-K amount so it nets to zero. For 2022 and 2023 returns, it describes reporting the proceeds on Schedule 1 with a matching adjustment, or using Form 8949 with code “L” in column (f).³
• If you sold at a gain, the IRS says “the gain on the sale of a personal item is taxable” and goes on Form 8949 and Schedule D.³

Check the current year’s IRS instructions for exact lines before you file.

Keep simple records

Even when no tax is due, keep:

• A bill of sale or receipt showing the date, price, buyer and VIN (see bill of sale for a junk car)
• A photo of the signed title
• What you paid for the car and any major improvements, if you have it

These help if you ever need to show the sale was at a loss, or answer a 1099-K.

Cases that work differently

• Business or mixed use. If you used the car in a business or claimed depreciation, the rules for business property apply, and the result can differ from a personal-use sale. Publication 544 covers sales of business assets.² A tax professional can help.
• Donating instead of selling. A deduction is possible, but generally only if you itemize, and usually limited to what the charity sells the car for.⁴ See junk vs donate.
• Insurance payouts on a totaled car. An insurance settlement isn’t a sale to a buyer, and casualty rules may apply. See selling a totaled car and ask a tax professional.
• State taxes. This guide covers federal rules only. Check your state’s revenue department for how it treats the sale.

Bottom line

Sell the car, keep the paperwork, and in the usual case, where it sold for less than you paid, there’s nothing to deduct and no tax to pay. If it sold at a gain or you received a 1099-K, report it as the IRS describes. When you’re ready, you can get an offer for your car.
