In Italy it is possible to assign a small part of your taxes to a non-profit organization or association. This quota is called 5×1000 and in fact represents 0.5% of the IRPEF taxes paid.
If the citizen decides not to assign this share to anyone then it remains with the State.
If you pay taxes in Italy or have relatives or friends in Italy who may decide to assign this amount to Colomitalia: here you will find the page in Italian with all the explanations.
