Form 1098-C Instructions: What Charities Need to Know About Reporting Vehicle Donations

Updated: June 11, 2026

Form 1098-C reporting depends on what the charity does with the donated vehicle after receiving it. This article breaks down the Form 1098-C instructions for filing triggers, box-by-box reporting, 30-day deadlines, and common mistakes charities should avoid.

What Form 1098-C Is and Why It Matters

Form 1098-C is the IRS form a qualified donee organization uses to acknowledge and report certain donations of motor vehicles, boats, and airplanes. It generally applies when the donor claims the donated property is worth more than $500.

A donee organization must file one Form 1098-C with the IRS for each reportable vehicle donation when the donor claims its value is more than $500. For the charity, the form is both an IRS filing record and the donor’s deduction acknowledgment.

When the deadline is missed or the vehicle record is incomplete, the charity may have to make corrections, and the donor may have trouble supporting the deduction.

Who Must File Form 1098-C and When It Applies

A charity or other qualified donee organization must issue Form 1098-C when it receives a reportable qualified vehicle donation. A separate form is generally prepared for each reportable vehicle. A qualified vehicle means a motor vehicle mainly built for use on public roads, streets, and highways, or a boat or airplane. Property the donor held mainly for sale to customers, such as dealer inventory, is not a qualified vehicle.

The form comes into play usually when:

  • An organization receives a donated car, boat, or airplane
  • The donor claims the vehicle is worth more than $500
  • The organization sells the vehicle, keeps it for significant intervening use, materially improves it, or gives it to a needy individual or sells it significantly below fair market value

This is why the question is not only when Form 1098-C is required. The charity also needs to know what it plans to do with the vehicle. That decision controls the reporting box and the furnishing deadline.

Form 1098-C Deadlines and Reporting Rules Charities Should Track

Form 1098-C does not work like a fixed year-end statement. It is an event-based acknowledgment form. The furnishing deadline depends on what the charity does with the vehicle after receiving it.

The timing rules are:

  • Furnish Form 1098-C within 30 days of the sale date if the vehicle was sold to an unrelated party in an arm’s-length sale.
  • If Box 5a applies because the vehicle will be significantly used or materially improved, furnish Form 1098-C within 30 days after the contribution date.
  • If Box 5b applies because the vehicle will be given or sold significantly below FMV to a needy individual, furnish Form 1098-C within 30 days after the contribution date.

This means the charity should track the contribution date, the sale date if a sale occurs, and the final disposition decision as early as possible. That helps ensure the correct box is used, and the acknowledgment is furnished on time.

How a Charity Determines the Correct Reporting Path for a Donated Vehicle

A charity should decide early how the donated vehicle will be handled, because that choice controls the box treatment and the timing.

A donor gets goods or services for the donation. When the donor gets any goods or services, the charity should mark Box 6a “Yes,” enter the value in Box 6b, and describe the goods or services in Box 6c.
