We have found out whether and what options there are to deduct the donation amount from your taxes.
According to our research, an application can be submitted 3 years after founding a "non-profit association ", but it is not easy to get this approval (unless your name is WWF, Helvetas or something similar).
We are now in the process of founding such a non-profit association and have therefore also introduced double bookkeeping. So we hope to have a chance in 3 years...
Until then, donors who wish to do so will be happy to receive a thank you letter from us.
