IRS gift tax move could hit new anonymous groups

The Internal Revenue Service appears to have begun to enforce a tax on gifts to the nonprofit organizations that were a key vehicle for anonymous politics in the last five years and had promised to play a large role in the presidential cycle, a move which could reshape the place of money in politics in 2012.

"It appears that the IRS Estate and Gift Tax team has also started paying attention to 501(c)(4) organizations," a Los Angeles tax lawyer who has followed the issue closely, Ofer Lion, wrote in a memo to clients.
