The IRS said funding from the Inflation Reduction Act has helped it go after wealthy taxpayers who failed to pay their tax bills.

The IRS said Friday that it has recovered $1.3 billion in unpaid taxes from high-income Americans who had either failed to file their returns or who hadn’t fully paid what they owed.

The announcement, made jointly with the U.S. Treasury Department, is aimed at highlighting the agency’s ramped-up enforcement efforts against tax cheats, which have been funded under the 2022 Inflation Reduction Act.

That IRS funding has proved controversial, with some Republican lawmakers falsely claiming the money would be used to hire 87,000 new IRS agents to “to audit Walmart shoppers.”
