In the context of federal income taxes, the term 8283 refers to IRS Form 8283, which is titled Noncash Charitable Contributions. The form is the official document used to disclose and substantiate deductions for donated property when the total noncash deduction for the year is more than 500 dollars. It requires you to provide detailed information about each donated asset, including description, date acquired, method of acquisition, cost or basis, and fair market value at the time of the gift. For larger contributions it also captures appraisal details and signatures from both a qualified appraiser and the recipient organization. Among tax professionals, saying that a donation “needs an 8283” has become shorthand for a noncash gift that is significant enough to require this formal reporting and supporting documentation.
