Non-cash donations are the most common triggers of IRS audits, so it is important to keep thorough documentation of a car donation. Specifically, if your car is valued over $250, then you need to obtain and retain a written acknowledgment from the charity. Additionally, if your car is worth more than $500, you must complete section A of the IRS Form 8283 and attach it to your yearly taxes. Furthermore, if your car is worth over $5,000, then you must have an independent appraisal and fill out Section B of IRS Form 8283.
