Once in a while I intend to post either the answer to a question that comes up in conversation, or — if I can't find it anywhere — a plea for someone to tell me where to find an authoritative source. So when I say 'FAQ' I don't mean about this site. The first of this very occasional series has to do with tax rates. Total tax rates — federal plus state. Now, obviously this is very much an average since local taxes vary a lot. But it's still much more informative, I think, than just looking at the (seemingly more progressive) federal income tax alone. Throw in all taxes, and the picture looks quite different, practically flat.

And note that this data pre-dates the latest round of Bush tax cuts for rich folk.
