CBO punts on bill to stop IRS from implementing ObamaCare

Stripping the IRS's powers would chip away at the law's biggest expense — tax credits to help low-income individuals cover the cost of their premiums. 

The IRS could no longer provide advance tax credits, which would save the government money — but it also wouldn't be able to recover incorrect credits claimed through regular tax filings, the agency said.

The IRS also would be barred from enforcing the law's individual mandate, and it would have to stop collecting new revenues that offset the healthcare law's costs. Those revenue streams include taxes on insurance plans and medical devices.

The CBO also did not complete cost estimates for the two most recent anti-ObamaCare bills in the House.

None of the bills, including the IRS measure, are expected to go anywhere in the Democratic-controlled Senate.
