As we approach the end of another year of LDP abusse, I remembered
that there's some kind of special deduction you can take for
contributions to political parties (last year this was line 25 of form
A). The instructions merely reference another zeimusho document
(seitou nado kifukin tokubetu koujou wo ukerareukata he), which I
don't have, so I thought I would see if anyone here has any experience
or knowledge about it.

It looks like this is a straight tax credit (rather than a deduction
from taxable income), so if, for example, I'm liable for 1,000,000 yen
in national tax, then it seems like this credit would essentially
allow me to give 1,000,000 to the political party of my choice (i.e.
not the LDP) and owe no tax.

Does anyone know more about this? I figure there must be a whole stack
of special rules and exceptions, and there may not be time to do it
this year, but... I kind of like the idea of being able to say where
my tax money goes, even if it's only a part of it.

Thanks!

Tim
