A charitable deduction, generally, may only be taken on donation amounts greater than value received, so raffle ticket purchases are not deductible as charitable gifts. See the table on page 2 of IRS Publication 526. Entry fees to participate in games of chance are also not deductible as charitable contributions. The IRS considers the chance to win a prize to be something of value received in exchange for a donation. Source(s):
When it comes to purchasing auction items, donors cannot take a full deduction for the item; according to the IRS, only the fair market value of an item above what the donor paid for it is actually tax-deductible. For example, if a donor paid $40 for an item worth $30, they can deduct $10 for purchasing the item.
