Tax Deadline Extended To May 17, 2021

Governor Mike Parson announced on March 19, 2021, that the Missouri Department of Revenue is extending the state individual tax filing and payment deadline for the 2020 tax year from April 15, 2021, to May 17, 2021.

“As our state continues recovering from COVID-19, we understand that many Missourians are still feeling the effects of the past year,” Governor Parson said. “Extending the filing and payment deadline by one month will provide additional relief to Missouri families and tax professionals as they work to meet their obligations during what has already been a challenging tax season.”

This decision mirrors Wednesday’s announcement by the U.S. Treasury Department and the Internal Revenue Service (IRS) that individual taxpayers would receive automatic extensions to file and pay federal income tax for the 2020 tax year. The IRS has said it will issue formal guidance in the coming days.
