The Dream of the Kingdom of Aquarius

Where in friendship with water we live,
There the otter’s visage unblemished remains,
Its sanguinary desire for life the precious stays.
May our waters soon become
The kingdom of Aquarius again!

 The Personal Income Tax Act (Zakon o dohodnini) allows all taxpayers to dedicate up to 0,5 % of their personal income tax to non-governmental organizations, including the Institute Lutra. Donation of personal income tax to non-governmental organizations is free, since this amount would otherwise be left in the state budget but to us this financial contribution means a lot. You can send a request for a part of personal income tax electronically with a digital certificate (via eDavki system) or by post to the Finančni urad Ljubljana, Davčna ulica 1, 1000 Ljubljana.
