Form 8283 Noncash Charitable Contributions: A Donor's Guide to the $5,000 Qualified Appraisal Threshold and IRS Substantiation Rules
Form 8283 is required when total noncash charitable contributions exceed $500. Above $5,000, donors need a USPAP-compliant qualified appraisal and three signatures on Section B; over $500,000 the full appraisal attaches to the return. Section 170(o) can claw the deduction back if the charity disposes of tangible property within three years, and the 40% gross valuation misstatement penalty has no reasonable-cause defense.
