It is now more important than ever to have proper documentation of your charitable contributions, the IRS may ask for you to produce your documentation. The IRS may do this by sending you a letter asking you to forward a copy of documentation. While all contributions must be substantiated, contributions of $250 or more require a written receipt from the charity. If you donate property valued at more than $500, additional requirements apply.
For a contribution of cash, check, or other monetary gift, regardless of amount, you must maintain a bank record or a written communication from the donee organization showing its name, plus the date and amount of the contribution. It’s not sufficient to maintain other written records, such as a log of contributions.
