IRS Form — Noncash Charitable Contributions

Form 8283 — Noncash Charitable Contributions

Form 8283 is required when a taxpayer claims a deduction for noncash charitable contributions exceeding $500. For contributions over $5,000, a qualified appraisal is required and the appraiser must sign Section B of Form 8283. For tax professionals, noncash charitable giving — particularly donations of appreciated stock, real estate, and art — is a high-value advisory area with significant documentation requirements.

Donating Appreciated Stock — The Most Tax-Efficient Charitable Strategy

Donating appreciated stock directly to a charity (rather than selling the stock and donating cash) is one of the most tax-efficient charitable strategies available. The donor deducts the full fair market value of the stock as a charitable contribution, and neither the donor nor the charity pays capital gains tax on the appreciation. For a client in the 37% bracket who owns $100,000 of stock with a $10,000 basis: if they sell the stock and donate the proceeds, they pay $18,000 in capital gains tax (20% + 3.8% NIIT) and donate $82,000. If they donate the stock directly, they deduct $100,000 and the charity receives $100,000 — saving $18,000 in taxes.

Frequently Asked Questions

My client donated a car to charity. How do they determine the deduction amount?
For donated vehicles, the deduction is generally limited to the gross proceeds the charity receives from selling the car — not the fair market value. The charity must provide a contemporaneous written acknowledgment (Form 1098-C) showing the gross proceeds from the sale. If the charity uses the car for its exempt purpose (rather than selling it), the deduction is the fair market value. If the charity sells the car for $500 or less, the deduction is the lesser of the fair market value or $500. The taxpayer must attach Form 1098-C to their return to claim the deduction.
