His resignation also followed continued digging by a Missouri House committee into the errors made last year.

The Columbia Daily Tribune also reported, shortly before Walters’ resignation, that the Department of Revenue planned to warn Missourians about the risk of surprise tax bills last year, but ultimately elected not to send out a news release imploring taxpayers to withhold more from their paychecks.

“The decision to take more money out of paychecks without following the law shows a clear pattern of mismanagement,” Galloway told reporters Tuesday, “and the resignation of one unelected bureaucrat does not equate to accountability.”

She said the 2019 changes required public input.

Because of the state’s mistakes last year, Galloway’s office said, Missourians owe an additional $134 million when filing their returns this year, and the state will pay out $232 million less in tax refunds.

In response to Galloway’s audit, Walters sent a brief letter to Galloway on March 18 saying the state would “take steps to inform taxpayers of the potential impact of changes made to the state’s withholding tables.”
