Per BNA, Senate Finance Committee chair Max Baucus (D-MT) indicated today that the Committee may move to a mark-up of a one-year AMT patch as early as next week. Baucus estimates the cost of the patch at $55 billion but added "It's difficult to come up with offsets that will pass." Committee ranking member Charles Grassley (R-IA) has long said that he prefers forgoing offsets even for an AMT patch, but Baucus says that "my preference is not to waive" PAYGO. Such a waiver would require 60 votes in the Senate. As for which offsets Baucus is considering, he specifically mentioned that closing the carried interest tax preference for fund managers and requiring publicly traded partnerships (PTPs) engaged in investment management services to pay the 35 percent corporate tax rate are "both on the table." While neither of these potential offsets has been scored by the JCT -- indeed, neither has the AMT patch -- informal estimates put 10-year revenue figures for the carried interest proposal somewhere in the $50 billion ballpark while PTP reform is thought to add a small fraction of that figure.
