We've created this stepbystep guide on everything you need to know about creating a donation receipt letter for tax purposes. Donors must have a bank record or written acknowledgment from the nonprofit before claiming a tax deduction for a charitable contribution.Keep a record of any items you donate to a charity. The Donation Value Guide below helps you determine the approximate tax-deductible value of some of the more commonly donated items. Please ensure that you select the correct receipt for the nonprofit at the location at which you donated. In that case, all you need to provide in the donation receipt is the name and EIN of the organization, date of donation, and a description of the donated item. You will receive a pay stub and a letter of receipt detailing the net cash value of the time donated.
