What about taxes? Can you pay taxes by credit?

I have not heard of a Gov't that takes credit card directly but since credit cards will let the holder obtain a "cash advance" and many cards now supply you with cheques you can write which clear through to your card balance then the answer is "yes" you could pay taxes by credit card.

California accepts credit cards for personal income tax.

What about taxes? Can you pay taxes by credit?

I have heard that old people in California can have the city put a lien on their house for the value of property taxes instead of paying property taxes. With property taxes of 1% of the house value and "house value" increases of only 2% per year (due to proposition 13), a house just increasing at the rate of inflation shouldn't have too much difficulty maintaining additional yearly liens until the owner dies.
