Understanding IRS Form 1098-C
Donating your car to charity can feel like a win-win situation you're helping a cause you care about while potentially getting a tax deduction. But there's an important piece of paperwork that makes this arrangement official: IRS Form 1098-C. If you've donated a vehicle worth more than $500, this form is your ticket to claiming that deduction on your tax return.
Let's walk through everything you need to know about this form, from why it exists to what each box means for your taxes.
What Is Form 1098-C?
Form 1098-C, officially titled "Contributions of Motor Vehicles, Boats, and Airplanes," is a tax document that charitable organizations must send to donors when they receive a vehicle donation valued at more than $500. Think of it as a receipt, but one that the IRS requires to have very specific information.
The form serves two purposes: it gives you the documentation you need to claim a charitable deduction on your tax return, and it helps the IRS verify that the donation actually happened and that the deduction amount is legitimate.
Why Does This Form Exist?
Before 2005, vehicle donation deductions were something of a Wild West situation. Donors could claim the fair market value of their vehicles based on guides like Kelley Blue Book, regardless of what the charity actually received when they sold the car. A vehicle listed at $3,000 might only sell for $1,200 at auction, but the donor could still deduct the full $3,000.
Congress decided this system was too open to abuse, so they created new rules requiring charities to report exactly what happened to donated vehicles. Form 1098-C was born from these reforms, bringing more transparency to the process.
When You'll Receive This Form
You should receive Form 1098-C within 30 days of your vehicle donation, but the exact timing depends on what the charity does with your vehicle:
- If the charity sells your vehicle, you'll receive the form within 30 days of the sale
- If the charity plans to keep and use the vehicle (or give it to someone in need), you'll receive it within 30 days of the donation itself
The charity will send you a copy of the form, and they'll also file a copy with the IRS, so the agency knows to expect a deduction claim on your return.
How Much Can You Deduct?
This is where things get a bit more nuanced. The amount you can deduct depends on what the charity does with your vehicle:
If the charity sells the vehicle
Your deduction is limited to the actual gross proceeds from the sale. So if your car's Blue Book value is $4,000 but the charity sells it at auction for $2,500, your deduction is $2,500. This is the most common scenario.
If the charity uses the vehicle
If the organization keeps the car for its own use (like a van for transporting clients) or gives it to someone in need, you can generally deduct the fair market value of the vehicle. However, the charity must provide a written statement explaining how they'll use it, and they must actually use it for a significant period.
If the charity makes material improvements
Sometimes a charity will fix up a vehicle before selling it or using it. In these cases, you might be able to deduct fair market value instead of the sale price, but this is relatively rare.

Understanding Each Box on Form 1098-C
Box 1: Date of Contribution
This is the date the charity received your donated vehicle. This date determines which tax year you can claim the deduction. If you donated your car on December 28, 2025, you'd claim the deduction on your 2025 tax return, even if the charity didn't sell the vehicle until January 2026.
Box 2:
Box 2a: Odometer mileage
Box 2b: Year of the vehicle
Box 2c: Make (manufacturer)
Box 2d: Model
This information helps establish the vehicle's condition and value.
Box 3: Vehicle or Other Identification Number
This box contains the vehicle identification number (VIN) for a motor vehicle, the hull identification number for a boat, or the aircraft identification number for an airplane. This unique identifier confirms which specific vehicle you donated.
Box 4a: Certification of Arm's Length Sale
This checkbox is marked if the charity sold your vehicle for more than $500 to an unrelated party in an arm's length transaction (a fair market transaction between independent parties). This is the most common scenario for vehicle donations. When this box is checked, your deduction is limited to the amount shown in Box 4c.
Box 4b: Date of Sale
If Box 4a is checked, this shows when the charity sold your vehicle. This date may be different from the contribution date, but remember you claim the deduction in the year shown in Box 1 (the contribution date), not the sale date.
Box 4c: Gross Proceeds from Sale
This is one of the most important boxes. If Box 4a is checked, this shows the actual sale price the charity received. This amount is typically your deduction limit, regardless of what you thought the vehicle was worth. If the charity sold your car for $2,500, that's generally your maximum deduction, even if the Blue Book value was $4,000.
Box 5a: Certification of Material Improvement or Significant Use
This box is checked if the charity certifies that they won't sell the vehicle before completing significant improvements or using it substantially for their charitable purposes. Examples might include a van the charity will use to transport clients or a vehicle they'll repair extensively before using. If this box is checked, you can generally deduct the vehicle's fair market value instead of a sale price.
Box 5b: Certification of Transfer to Needy Individual
This box is checked if the charity certifies they'll give (or sell at well below market value) your vehicle to a needy individual as part of their charitable mission to help the poor or underprivileged. If this box is checked, you can generally deduct the vehicle's fair market value.
Box 5c: Description of Improvements or Use
If Box 5a or 5b is checked, the charity must provide specific details here. For Box 5a, they'll describe the material improvements they made or the significant way they used the vehicle and for how long. For Box 5b, they'll explain how giving away the vehicle furthers their charitable purpose of helping those in need.
Box 6a: Goods or Services Provided
This is a simple Yes/No question: Did the charity provide you with goods or services in exchange for your vehicle donation? In most vehicle donations, the answer is "No" you simply donate the car and receive nothing in return except the potential tax deduction and perhaps a good feeling.
Box 6b: Value of Goods and Services
If the charity answered "Yes" to Box 6a, this box shows their good-faith estimate of the value of whatever goods or services they provided you. This amount typically reduces your deductible contribution. However, see Box 6c for an important exception.
Box 6c: Description and Religious Benefits Certification
This box serves two purposes. First, if the charity provided goods or services, they should describe them here. Second, there's a checkbox for the charity to certify that any goods or services provided consisted solely of "intangible religious benefits" (like admission to a religious ceremony). If this box is checked, you don't have to reduce your deduction by the value of those religious benefits.
Box 7: $500 Deduction Limitation
If this box is checked, your deduction is limited to the smaller of $500 or the vehicle's fair market value on the date of contribution. This box is checked when none of the scenarios in Boxes 4a, 5a, or 5b apply essentially, when the vehicle was sold for $500 or less, or in certain other unusual circumstances.
How the Boxes Work Together
The key to understanding Form 1098-C is recognizing that only one scenario applies to your donation:
Most common scenario
Box 4a is checked (charity sold the vehicle). Your deduction equals the amount in Box 4c (gross proceeds), or fair market value if lower.
Less common
Box 5a is checked (charity will use or improve the vehicle). Your deduction generally equals fair market value.
Less common
Box 5b is checked (charity will give vehicle to needy person). Your deduction generally equals fair market value.
Rare
Box 7 is checked. Your deduction is limited to $500 or fair market value, whichever is less.
Understanding which boxes are checked helps you determine your allowable deduction amount and what documentation you might need when filing your tax return.
How to Use Form 1098-C When Filing Your Taxes
Once you have Form 1098-C in hand, you'll need to take a few steps to claim your deduction:
1. Attach the form to your tax return
You must include a copy of Form 1098-C (or a similar written acknowledgment) when you file your taxes. Don't just keep it in your records it needs to go to the IRS with your return.
2. Complete Form 8283
If your vehicle donation is worth more than $500, you'll need to fill out Section A of IRS Form 8283, "Noncash Charitable Contributions." This form asks for details about the donation, including information from your 1098-C.
3. Itemize your deductions
Vehicle donations are only deductible if you itemize deductions on Schedule A. If you take the standard deduction, you won't be able to claim your vehicle donation. Given current standard deduction amounts ($14,600 for single filers, $29,200 for married filing jointly in 2024), you'll need substantial deductions to make itemizing worthwhile.
4. Keep your records
Hang onto Form 1098-C along with any other documentation about your vehicle's value, condition, and the donation process. The IRS can request these records if they have questions about your return.
Common Situations and Special Circumstances
What if the sale price seems too low?
Unfortunately, if the charity sells your vehicle in a legitimate sale, that's your deduction limit, even if you think it's worth more. Charities often sell donated vehicles at auction, where prices tend to be lower than private-party sales. There's not much you can do about this, but knowing it upfront can help set expectations.
What if you didn't receive Form 1098-C?
Contact the charity immediately. They're required to provide this form, and you can't claim the deduction without it. If the charity is unresponsive, you may need to forgo the deduction or consult a tax professional about your options.
What about vehicles worth $500 or less?
You don't need Form 1098-C for donations under $500, though you'll still need a receipt from the charity. Your deduction is limited to the vehicle's fair market value, and you'll need to determine this yourself using pricing guides while honestly accounting for the vehicle's condition.
Can you donate to any charity?
Only donations to qualified 501(c)(3) organizations are deductible. You can verify an organization's status using the IRS's Tax Exempt Organization Search tool on their website. Donations to individuals, political organizations, or foreign charities generally aren't deductible.

Frequently Asked Questions
Do I need Form 1098-C if my car is worth less than $500?
No, Form 1098-C is only required for vehicle donations valued over $500. For smaller donations, you just need a receipt from the charity showing the organization's name, the donation date, and a description of the vehicle.
Can I claim the Kelley Blue Book value instead of the sale price?
Only if the charity uses or improves the vehicle rather than selling it. If they sell it you must use the gross proceeds, regardless of pricing guide values.
What if my Form 1098-C has errors?
Contact the charity immediately to request a corrected form. Filing your tax return with incorrect information can lead to problems if the IRS compares your return to the charity's filing.
When should I expect to receive Form 1098-C?
Within 30 days of the sale (if the charity sells the vehicle) or within 30 days of the donation (if the charity keeps it). If you haven't received it within this timeframe, reach out to the charity.
What if I donated my car in December but the charity didn't sell it until January?
You claim the deduction in the year you made the donation (the date in Box 4a), not the year the charity sold it. So a December donation goes on that year's tax return, even if the charity sells it in January and you don't receive the form until then. Just make sure to receive the form before filing your return.
Can I deduct expenses related to donating the vehicle, like towing fees?
Generally no. You can't add expenses to your deduction amount. However, if you pay for something like a title transfer that the charity normally would have paid, you might be able to add that to your contribution amount. Consult a tax professional for specific situations.
What if the charity gives me something in return, like tickets to an event?
If you receive goods or services worth more than token value, you must reduce your deduction by the fair market value of what you received. The charity should indicate this in Box 7 of Form 1098-C.
Do I need an appraisal for my donated vehicle?
Not usually. Unlike other property donations over $5,000, vehicle donations don't require formal appraisals because the deduction is typically based on the actual sale price reported on Form 1098-C, not an estimated value.
What if I donated a boat or airplane instead of a car?
The same rules apply. Form 1098-C covers motor vehicles, boats, and airplanes.
Can I claim a deduction if I donated my car to someone in need directly?
No. To claim a charitable deduction, you must donate to a qualified charitable organization, not directly to an individual. Even if the charity gives your vehicle to someone in need, the donation must go through the charity for you to claim a deduction.
Final Thoughts
Form 1098-C might seem like just another piece of tax paperwork, but it plays an important role in ensuring that vehicle donation deductions are legitimate and properly reported. While it can feel a bit disappointing to see that your car sold for less than you hoped, the system is designed to reflect the real value that charities receive from vehicle donations.
The key to navigating Form 1098-C successfully is understanding what information it contains and how that information determines your deduction amount. Keep the form with your tax records, double-check that all the information is accurate, and don't hesitate to contact the charity if something seems wrong.
Whether you're donating an old sedan that's seen better days or a boat you no longer use, understanding Form 1098-C helps you make informed decisions about charitable giving and ensures you're claiming the correct deduction come tax time. And while the tax benefit is nice, remember that the real reward of vehicle donation is supporting causes that matter to you.
