This payment receipt includes the organization’s tax ID number and confirms that the person has made a donation as a charitable contribution and that they’re not receiving any goods or services in return.

Donors through Facebook Fundraisers may also find their donation under “Payment History” on Facebook, where a receipt can be printed.
