Only the funding recipients are able to emit a donation receipt. You can therefore request it directly to the project owner.
Donation receipt - Cerfa administrative form
Only general interest organizations or foundations or associations recognized as being of general utility can deliver them. When it is the case, this is clearly displayed on the project description, and with a dedicated section saying "Your donation is eligile for a tax reduction of 66% if you are a French resident" under the "Back this project" button.
Donation receipt - Invoice
Only the funding receipient - the project owner - is able to send you a donation receipt. Please get in touch with them if you need one.
⚠️ The donation receipt can only be delivered once the campaign is over and successful. These two conditions are necessary to officialize the donation.
