It depends. For noncash donations under $250 in value, you'll need a receipt unless the items were dropped off at an unmanned location such as a clothing bin.
Noncash donations from $250 to $500 in value require a receipt that includes the charity's name, address, date, donation location and description of items donated.
Noncash donations over $500 in value also require a record of how and when the items were acquired and their adjusted basis. If the donation exceeds $5,000 in value, it'll need a written appraisal from a qualified appraiser.
