This Monday marks the beginning of tax filing season, when the IRS will begin accepting 2021 income tax returns from individuals and businesses. Most people have until April 18 to submit them this year.

As it starts to accept this year’s returns, the IRS is still working through millions filed last year. And that’s just one of its problems.

“The service is in the roughest shape it’s been in in 50 years,” says Mark Everson, who served as IRS commissioner in the George W. Bush administration.
