The Internal Revenue Service will furlough nearly half its staff this week as the government shutdown drags on with no end in sight.

The IRS is already operating at a reduced workforce, which fell from about 100,000 employees at the end of 2024 to roughly 75,000 when the shutdown started, the Associated Press reported. Its initial Lapsed Appropriations Contingency Plan only provided for the first five business days, after which it turned to funds from the Inflation Reduction Act. With that running out, the agency will furlough 46.4% of employees.
