If you have made donations to the guifi.net Foundation in 2023, you can obtain tax advantages on your Spanish Income Tax Return or Spanish Corporate Tax.
The AEAT has the data and you will find it in the draft of the income tax return, but you can ask us, starting February 15, for the certificate by sending us an email to fundacio@guifi.net, so we will send it to you in case you need it. You can need it for the Spanish Corporate Tax or if it will not appear in the draft of the Spanish Income Tax Return.
