Incidentally, my major headache this week has been dealing with these credits that are not deductible as charitable contributions, but can be deducted as tax payments, if you haven't already met the $10K limit.  If not, you have to scroll down to the bottom of the form --  at least on my screen, you don't see it until you scroll down -- and enter a zero where it asks how much is being deducted on Schedule A.  I'm not sure I have done all of them right this year, but I don't worry too much about the anarchists who don't want to fund police and fire.
