What to Do When Donating a Car: 1098-C, Appraisals, and Penalties

The tax deduction for donating a car to charity is usually capped at whatever the charity sells the vehicle for, not the Kelley Blue Book figure you had in mind, and you only get any benefit at all if your total itemized deductions clear the standard deduction for your filing status. For 2026, that means beating $16,100 as a single filer or $32,200 as a married couple filing jointly before the donation moves your tax bill by a single dollar.¹

How the Deduction Amount Is Calculated

Most donated vehicles end up at auction, and the IRS rule is blunt: your deduction is generally limited to the gross proceeds the charity receives when it sells the car.² Donate a car you valued at $4,000, watch it sell for $1,800, and $1,800 is your deduction. Auction prices almost always come in under the private-party values printed in valuation guides, so expect the write-off to be smaller than the number you carried around in your head.

Three exceptions let you claim the vehicle’s fair market value instead of the sale price:

The charity puts the car to significant use in its programs, such as meal deliveries or patient transport.²
The charity sells or transfers the car to a needy individual well below market price as part of its mission to help low-income people.²
The charity makes material improvements that significantly increase the vehicle’s value before selling or using it.

There’s also a floor for low-value cars. If the charity sells your vehicle for $500 or less, you can deduct either $500 or the car’s fair market value, whichever is less. A tired sedan worth $300 that hammers down at auction for $150 still gets you $300. A car worth $700 that sells for $400 gets you $500.

Confirm the Charity Actually Qualifies

Your deduction is zero unless the recipient holds tax-exempt status under section 501(c)(3) of the Internal Revenue Code. That covers most religious organizations, schools, hospitals, and nonprofits doing charitable, scientific, or educational work, and only 501(c)(3) organizations can receive contributions that are deductible under section 170.³

Before handing anyone the keys, look the charity up in the IRS Tax Exempt Organization Search on irs.gov. A group that lost its status last year won’t appear, and the IRS won’t care that the name sounded legitimate. Ask how the organization plans to use the vehicle too. If it drives donated cars in its own programs, you may qualify for the fair-market-value exception. If it auctions everything, plan on the sale-price rule.

Paperwork That Makes or Breaks the Write-Off

Sloppy documentation is the single most common reason car-donation deductions get rejected. Pull this together before you contact anyone.

Title and Odometer

You need a clear title in your name. If a loan or lien is still recorded, most charities won’t accept the car; you have to pay the loan off and get a lien-free title first. Sign the title’s transfer section as the seller, enter the charity’s full legal name as the buyer, and record the date. Never leave the buyer line blank for the charity to fill in later.

Federal law also requires you to disclose the vehicle’s mileage on the title at transfer. Record the odometer reading, certify whether it reflects actual mileage, and sign. The charity signs it too and gives you a copy.⁴ If the odometer has rolled over or is broken, check the box that says the reading isn’t reliable. False mileage statements can bring fines and prison time.

Written Acknowledgment at Pickup

For any contribution of $250 or more, the IRS requires a contemporaneous written acknowledgment from the charity. It has to include the organization’s name, a description of the vehicle, the date of the contribution, and a statement about whether the charity gave you any goods or services in return.⁵ Get this receipt when the car leaves your hands.

Form 1098-C

The charity has to send you Form 1098-C (or an equivalent written statement) reporting what happened with the vehicle. Deadlines depend on what the charity does:⁶

If the charity sold the car, you should receive Form 1098-C within 30 days of the sale, showing the gross proceeds.⁷
If the charity is keeping the car or transferring it to a needy individual, the form should arrive within 30 days of the contribution, certifying the intended use.⁷

You cannot claim a deduction of more than $500 without attaching Form 1098-C or an equivalent statement to your return.⁸ If 30 days pass with no form, call the charity.

Appraisal for Cars Over $5,000

When your claimed deduction exceeds $5,000, the IRS requires a written appraisal from a qualified appraiser.⁸ A printout from a valuation site won’t do. The appraiser has to hold a recognized designation or meet the IRS’s minimum education and experience standards, regularly appraise for pay, and show specific knowledge of valuing vehicles.⁹

Timing is strict. The appraisal must be signed and dated no earlier than 60 days before the donation, and you must have it in hand by the due date (including extensions) of the return on which you first claim the deduction. The appraiser signs Part IV of Form 8283, Section B; the charity then completes and signs the donee acknowledgment in Part V and returns it to you before you file.¹⁰ A missing signature is a common and entirely avoidable way to lose the deduction.

Itemizing, the Standard Deduction, and the New 0.5% Floor

The car-donation write-off only exists if you itemize on Schedule A. Your total itemized deductions, including the car, have to exceed the standard deduction for your filing status. For tax year 2026:¹

Single or married filing separately: $16,100
Married filing jointly or surviving spouse: $32,200
Head of household: $24,150

Say you donate a car that sells at auction for $2,500 and your other itemized deductions (state taxes, mortgage interest, medical) total $12,000. Combined, that’s $14,500, still below the $16,100 single-filer standard deduction. The car donation produces no tax benefit because you’re better off taking the standard deduction. This is the arithmetic that catches donors off guard.

Starting in the 2026 tax year, a new rule under the One Big Beautiful Bill Act says itemizers can’t deduct the first 0.5% of their adjusted gross income in charitable contributions. If your AGI is $100,000, the first $500 of your total charitable giving (car donation included) produces no deduction. At an AGI of $200,000, the nondeductible floor is $1,000. The floor doesn’t erase the deduction for most donors, but it trims it.

Even after clearing the standard deduction and the 0.5% floor, your charitable deduction generally can’t exceed 50% of your AGI for donations to public charities. Lower ceilings of 30% or 20% apply in some cases, such as gifts to certain private foundations.¹¹ Excess amounts carry forward for up to five years.

For any noncash contribution over $500, you file Form 8283 with your return. Section A covers donations valued between $500 and $5,000. Section B applies above $5,000 and requires the appraiser signature and charity acknowledgment described above. Attach Form 1098-C or a comparable statement for any vehicle deduction over $500.⁸

You Cannot Donate a Partial Interest

One rule surprises people: you can’t donate a car to a charity while continuing to use it on weekends or keeping partial ownership. The IRS treats a gift of the right to use property as a contribution of less than your entire interest, and it generally denies the deduction.¹² When you donate the car, you donate all of it.

Penalties for Overvaluing the Car

Inflated valuations carry specific accuracy-related penalties. Claim a value that’s 150% or more of the correct value, with an underpayment of tax over $5,000, and you owe a 20% penalty on the underpayment. Push the claim to 200% or more of correct value with the same $5,000 underpayment, and the penalty doubles to 40%.¹³ These penalties stack on top of the back taxes and interest already owed.

A $3,000 deduction on a car actually worth $1,500 doesn’t sound like a stretch, but that ratio (200%) is exactly where the 40% penalty kicks in. Use the condition categories in Kelley Blue Book or NADA Guides the way they’re intended, and if the vehicle is valuable enough to warrant an appraisal, pay for one.
