Senate Finance Chairman Orrin HatchOrrin Grant HatchCongress, stop holding 'Dreamers' hostage Drug prices are declining amid inflation fears The national action imperative to achieve 30 by 30 MORE (R-Utah) wants the IRS's watchdog to investigate why hundreds of thousands of people who received tax breaks under ObamaCare didn't file their taxes this year.
John Koskinen, the IRS commissioner, told Hatch on Friday that 710,000 taxpayers who received tax credits to help purchase insurance under the Affordable Care Act had yet to either file or seek an extension.
Hatch estimated that those taxpayers received more than $2.4 billion worth of tax breaks, given that the average credit in the healthcare law was worth $3,400.
The Utah Republican, in asking the Treasury inspector general for tax administration to examine the matter, said that Koskinen's letter "raised serious questions" about the Obama administration's management of the tax credit.
"While it is likely that not all of these are fraudulent, because of the marketplace’s lax integrity controls there is reason to believe that a significant portion are fraudulent," Hatch said about the 710,000 tax credit recipients.
Hatch added that a Government Accountability Office investigation had found that the federal ObamaCare exchange approved 11 of 12 fake applications for the healthcare incentive.
Senior Treasury officials have made it clear that there will be consequences for taxpayers who didn't file after taking advantage of ObamaCare credits.
Koskinen and other IRS officials have widely praised the agency's implementation of the Affordable Care Act this year, even as they argue that the IRS needs an increased budget.
The IRS chief told Hatch in his letter that "with the exception of the continued erosion of taxpayer services, the 2015 tax filing season has gone smoothly, generally, and as it relates specifically" to ObamaCare.
