The CBO estimate does include the tax provisions in the introduced version of the Bill (see footnote 1).

The details, and the source of the $583 billion overall total revenue number, can be found here.

The tax increases are itemized as follows:

A. Impose a Surcharge for Certain AGI at the Following Rates: 1% for $350,000-$500,000 for Joint Returns for 2011 Through 2012, 2% in 2013 and Thereafter; 1.5% For $500,000-$1,000,000 for Joint Returns for 2011 Through 2012, 3% In 2013 and Thereafter; 5.4% for $1,000,000 and Above for Joint Returns for 2011 and Thereafter; Income
Thresholds are Indexed for Inflation

These tax increases on "the rich" amount to 93 percent of the tax provisions in the bill. All the other tax provisions are pretty much lost in the noise.
