Question from a client: One of the charities I donate to told me that I don't need a receipt unless I donate $250 in one year...is this true...even if I get audited? Answer: Yes.
This comes up every tax season and seems to be something people don't understand. On Schedule A, for itemized deductions, there's no such thing as a "$500 standard deduction for non-cash charitable contributions."
The short answer is, there's really no special documentation you need, because it's technically not a charitable deduction.
