GOP preparing bill to deny funds for IRS ObamaCare agents

Republican Sen.

The scandal has prompted fears that the IRS is incapable of neutrally enforcing major provisions of the healthcare reform law, including its individual mandate to buy insurance. 

"It is necessary that both Congress and the Department of Health and Human Services [HHS] look closely at the money given to the IRS through the healthcare law," Heller wrote to HHS Secretary Kathleen SebeliusKathleen SebeliusOPINION | 5 big ideas to halt America's opioid epidemic Aligning clinical and community resources improves health Sebelius on GOP healthcare plan: 'I'm not sure what the goal is here' MORE on Tuesday.

Policy experts say the Affordable Care Act created strict guidelines that federal tax officials will need to follow, but Republicans question whether the IRS can be trusted to remain nonpartisan as it implements President Obama's signature law. 

"I believe we need to address [the issue] now, which may mean calling for a temporary suspension until it is clearer where this funding will go," Heller wrote.

The IRS is responsible for the Affordable Care Act's individual mandate, and the tax subsidies that millions of people will receive to help them buy health insurance. The agency will also manage the law's new streams of tax revenue from healthcare stakeholders.

Heller's bill would suspend funding for new employees to carry out those functions, his office said. The measure is expected later in the week.
