As House Republicans and the White House wrangle over a debt-ceiling deal, one GOP demand ought to be nonnegotiable. A politicized Internal Revenue Service has no business keeping its untrustworthy fingers on last year’s $80 billion cash infusion.

This week brought two more examples of IRS roguery that build on its already unsavory record of leaks, incompetence and partisan behavior. The first is the alarming story of journalist Matt Taibbi, who may have been targeted by the IRS in retribution for documenting the joint censorship efforts of Big Tech and the federal government.

Mr. Taibbi in March told the House Judiciary Committee a disturbing tale: an IRS agent had made a surprise visit to his New Jersey residence on March 9—the same day Mr. Taibbi testified before another House committee about censorship at Twitter. The journalist was subsequently told there were “identity theft” concerns with his 2021 and 2018 tax returns. The 2018 claim particularly troubled Mr. Taibbi, since his accountants possessed documentation showing the return had been electronically accepted, and neither they nor he had ever received notification of a problem. Judiciary Chairman Jim Jordan demanded the IRS explain.
