A donation to a nonprofit through its Facebook Page or a fundraiser on Facebook may be tax-deductible. Since tax laws vary by country and region, you should consult a tax professional or review the laws for your area to determine whether a donation is tax-deductible. Your email reciept will have the nonprofit's info, including the EIN.

After you make a donation, a confirmation will be sent to the primary email listed on your Facebook account. This confirmation shows that you've made this donation as a charitable contribution and that you're not receiving any goods or services in return.
