Additional Revenue when the "Bush Tax Cuts" expire

[1-Old-Man]

I think I have the worst search ability of any person who uses the Internet. For the life of me I can not find the answer to this simple question. How much additional annual revenue will the Federal Government take in as a result of the expiration of the Bush Tax Cuts, beginning at the end of the year? Have any of you all seen any rational estimates?

1. I heard the figure $23 billion yesterday

It was mentioned on UP with Chris Hayes, but I don't remember what time frame they were talking about.

2. "Without any extensions, the expiration would raise taxes next year by $221 billion."
