More than 1,000, according to Paul Bedard of U.S. News:
The Internal Revenue Service says it will need an battalion of 1,054 new auditors and staffers and new facilities at a cost to taxpayers of more than $359 million in fiscal 2012 just to watch over the initial implementation of President Obama's healthcare reforms. Among the new corps will be 81 workers assigned to make sure tanning salons pay a new 10 percent excise tax. Their cost: $11.5 million.
At least the IRS can put a number on how many new staffers it will take to enforce the law. When staffers at the Congressional Research Service were asked to estimate the number of new bureaucratic entities the health care overhaul will create, they reported that the task was "impossible" because the true number was "unknowable."
