IRS Form 8283 is required for claiming a tax deduction when you donate a car valued over $500 to a qualified charity. You must attach it to your tax return. For vehicle donations exceeding $5,000, a formal, written independent appraisal is typically mandatory, and its details must be recorded on Section B of this form.
The form’s primary purpose is to document noncash charitable contributions, ensuring the IRS has a record of significant donations. It is not exclusive to cars; it applies to various property types like furniture, equipment, or securities. Accurate completion is critical for compliance and to avoid triggering an audit.
The process depends on your vehicle’s claimed fair market value and how the charity uses it.
Appraisal requirements are specific. The appraisal must be obtained before filing your return and no more than 60 days before the donation date. The appraiser must sign Part III of Section B. Failing to secure a required appraisal can lead to deduction disallowance.
Post-donation, the charity must provide you with Form 1098-C, “Contributions of Motor Vehicles, Boats, and Airplanes,” within 30 days of the sale or 30 days of the donation if they keep the vehicle for their use. The information on Form 1098-C is essential for accurately completing your Form 8283 and tax return.
Submitting incomplete or inaccurate Form 8283 is a common audit trigger. Ensure every applicable line is filled, signatures are obtained where required, and the form aligns with the information on your Form 1098-C and appraisal documents.
The table below summarizes key thresholds and actions:
| Claimed Deduction Value | Form 8283 Section Required | Appraisal Needed? | Charity Form 1098-C Required? |
|---|---|---|---|
| $500 or less | None | No | Yes, if vehicle sold |
| Over $500 but ≤ $5,000 | Section A | No | Yes |
| Over $5,000 | Section B | Yes, with limited exceptions | Yes |
According to IRS compliance data, mismatches between donor , charity receipts, and appraisal documents are a primary focus for review. Maintaining a consistent paper trail is your best defense.

As a tax preparer, I see clients trip up on this form every year. They donate a car, get excited about the deduction, and then scramble at tax time. The rule is simple: if that car is worth more than $500 to the IRS, you need Form 8283. It’s your receipt to the government.
Over $5,000? That’s when it gets serious. You’ll likely need to pay for a professional appraisal before you file. The charity can’t give you that number. Save yourself a headache—get the appraisal done within the right timeframe and make sure the appraiser fills out their part of the form. Missing that step is the fastest way to lose your deduction.

I donated my old SUV last year and thought the hard part was over once I handed over the keys. I was wrong. The paperwork was a project. The charity sent me a Form 1098-C a few weeks later, which showed how they used my car. My deduction was based on that.
Because my vehicle was valued at over $5,000, I had to hire an appraiser. He gave me a detailed report and helped me fill out Section B of the 8283. My takeaway? The donation itself is simple, but protecting your deduction requires careful attention to these forms. Don’t assume the charity handles it all; this tax form is your responsibility.

Think of Form 8283 as the bridge between your good deed and your tax benefit. The charity acknowledges your gift with Form 1098-C. You, in turn, document the value of that gift for the IRS with Form 8283.
Its main job is to prevent overvaluation. For high-value items, the IRS wants a third-party expert (the appraiser) to confirm the worth. That’s why signatures are required from you, the appraiser, and sometimes even the charity. It’s a system of checks and balances.
If your deduction is modest (over $500 but under $5,000), you only fill out Section A. It’s straightforward. The heavy lifting—Section B and the appraisal—is reserved for the most valuable contributions. Always match the information on your 8283 exactly to what’s on your 1098-C.

Let’s break down the logic behind this form. The IRS allows deductions for charitable contributions to encourage giving. However, noncash donations are easy to overvalue, intentionally or not. Form 8283 exists as a control mechanism, creating a verifiable paper trail for significant gifts.
From a strategic standpoint, you must determine the vehicle's fair market value first. Consult guides, local listings, or get an appraisal. This value dictates your entire path. If it’s $5,001, you are legally obligated to follow the more stringent appraisal process. There is no gray area.
The interaction with Form 1098-C is non-negotiable. If the charity sells your car, your deduction is usually the gross sale price they list on that form. Your Form 8283 must reflect this same amount. A discrepancy will flag your return.
The authority behind these rules is clear in IRS publications. Audits on noncash donations focus on valuation and proper form completion. The burden of proof is on you, the taxpayer. Properly completing Form 8283, with all required signatures and supporting documentation, is the only way to meet that burden and secure your legitimate deduction.
