Where can I find how much tax revenue from personal the US made in 2004?

Question

I found that personal income in 2004 was 9,702 billion, I am just curious how much of that was taxed.

Answer 1

go to the irs site. They have stats for that sort of thing. Although, I'm not sure if they have data compiled for 2004 yet.

The 2003 figures I have from the IRS says that:
Total Personal Taxable income was: 4,200,198,884
Total Personal Tax Revenue at all rate levels was: 780,309,227
That equates to: 18.6%
