The figure comes from an analyses of the Impact of the Inflation Reduction Act, which provided more funding for the IRS. It was immediately disputed by a leading Congressional Republican.
In 2022, the Congressional Budget Office estimated that new IRS funding would increase revenues by $180.4 billion from 2022 to 2031. The IRS says it can revenue could rise as much as $851 million by 2023 if funding restored, renewed and diversified.
The report is used by the administration to promote President Joe Biden’s efforts to fund the IRS in the face of Republican opposition.
“Congressional Republicans’ efforts to cut IRS funding show that they prioritize letting the wealthiest Americans and big corporations evade their taxes over cutting the deficit,” National Economic Adviser Lael Brainard said in a statement, quoted by an Associated Press announcement.
The same AP news item said Rep. Jason Smith, the Republican chairman of the House Ways and Means Committee, said the report “calls for even more IRS funding, uses pie-in-the-sky numbers, all without being straightforward about where the burdens of massive new enforcement efforts will fall.”
