5×1000 is a portion of tax which the State gives up for donation to non-profit organisations, in order to support their activities. If you decide not to allocate your 5×1000 to anybody in particular, it will go to the State.
5×1000 is not an additional tax and doesn’t cost you anything.
5×1000 does not replace the 8×1000 system relating to religious bodies. They are different things and both can be used.
