ST. LOUIS (AP) — A federal lawsuit seeks a return of the 1% St. Louis earnings tax paid by people who normally work in the city but instead worked from their suburban homes during the coronavirus pandemic.

The lawsuit filed Monday on behalf of three suburban St. Louis residents seeks class action status, the St. Louis Post-Dispatch reported. If successful, the lawsuit could cost the city millions of dollars.

The plaintiffs' attorney, Bevis Schock, said last year that he planned to file a class-action lawsuit after St. Louis Collector of Revenue Gregory F.X. Daily issued a policy barring city earnings tax refunds for employees working outside city limits.

Thousands of people who work in St. Louis but live outside the city have worked from home since March 2020 to slow the spread of the coronavirus, particularly white-collar office workers.

“The way we view it, you and your company have agreed (to have you) work at home. You’re still utilizing all the computer software that your company provides” from its base in the city," Daly told the Post-Dispatch in June.

More than one-third of the city’s general revenue comes from the tax, or about $180 million last year.

A city spokesman declined to comment.

The Missouri Department of Health and Senior Services on Wednesday reported 406 newly confirmed cases of COVID-19 and no new deaths. The state has reported 489,374 confirmed cases and 8,498 deaths since the pandemic began.
