I slept fitfully; got a heartbreaking call from my 18 year old college daughter wanting to know if she should pack her bag and come home now, since my taxes might go too high to keep her in college. :(
Actual new tax hikes from the Kenyan Clown and his Democrat Congress probably won't hit until at least fall of next year, and it is more likely to be even later than that, so those shouldn't be an immediate effect.
The ones that are automatic are the expiration of the temporary Bush tax cuts over the next three years. The tax on dividends will rise in 2009, as will capital gains taxes; income taxes are slated to automatically rise in 2011.
Heritage has a web page at http://www.heritage.org/Research/Taxes/wm486.cfm on the expiration of the Bush tax cuts.
