You'd better believe we pay careful attention to capital gains here. Friday, the Congressional Budget Office released an analysis of the rise and fall of federal individual income tax revenues from 1994 through 2004. It showed that capital gains accounted for half of the non-legislative changes to individual income tax revenues over the period. Ironically, capital gains revenues increased 0.7% of GDP from 1994 through 2000 under President Clinton, and they fell 0.6% of GDP from 2000 to 2004 under President Bush.
