“Under the health care overhaul, the federal government will start taxing itself and the states beginning in 2014. And that’s giving state Medicaid directors heartburn. A report released Tuesday by the actuarial firm Milliman Inc. said the tax will cost the Medicaid program between $36.5 billion and $41.9 billion over 10 years. At least $13 billion will be borne by states, and at least $23.5 billion by the federal government, based on the state-federal Medicaid matching formula.”
