According to Polish law, Benchen Karma Kamtsang Buddhist Association is not an organisation for public benefit, therefore it is not possible to transfer 1% of your income tax to the Association. Yet, you may give your 1% to the Benchen Monastery Free Dental Clinic, the free clinic in Benchen Monastery in Nepal.
Monetary donations offered to the Association for religious purposes may be deduced from the income tax taxation base. For details please visit: PIT.pl.
