Here is the bill text, all 2074 pages of it.
Here is the Joint Tax Committee estimate of the revenue effects.
I will update this post with a link to the CBO score when it’s available. Here is a document that I am told was handed out to Senate Democrats at their caucus meeting this evening. It appears as if it were drafted by Leader Reid’s staff. I believe this document is the basis for this evening’s news reports that “CBO says the bill costs $849 billion.” It is inaccurate for a news organization to report that CBO says this until they have seen an official CBO document.
Update: Here is my analysis of the tax increases in the bill.
Update 2: Here is CBO’s estimate.
