Following Feds, Gov. Parson announces Missouri tax filing deadline bumped to May 17

Last week, Missouri Gov. Mike Parson announced 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,” Gov. 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.
The Department of Revenue will automatically provide this filing and payment relief, so filers do not need to take any action to qualify.
Guidance on extension to file and pay individual income tax:
- Filing deadline extended: The deadline to file individual income tax returns has been extended from April 15, 2021, to May 17, 2021.
- Payment relief for individuals: The deadline to pay taxes owed on individual income tax returns with a due date of April 15, 2021, has been extended until May 17, 2021.
- This relief applies to individual taxpayers, including those who pay self-employment tax. However, it does not apply to estimated tax payments that are due on April 15, 2021; that deadline has not changed.
- Penalties and interest will begin to accrue on any remaining unpaid balances as of May 17, 2021. Individuals who file their return and pay their balance by May 17, 2021, will automatically avoid interest and penalties on the tax paid by May 17.
- Customers may still ask for an extension of time to file their individual income taxes. With that extension, the return will not be due until Oct. 15, 2021. However, any payments must still be made by May 17, 2021.
Earlier this year, the IRS announced that the nation’s 2021 electronic tax filing season would begin on Feb. 12. On that date, the IRS began accepting and processing e-filed 2020 tax year returns. Since e-filed state returns are first sent to the IRS, the department also began accepting and processing e-filed returns for the 2020 tax year on Feb. 12.
“With a delayed start and recent tax code changes, this tax season is a particularly complicated one,” said Director of Revenue Ken Zellers. “For Missourians who have yet to file, we strongly encourage you to file electronically and use direct deposit, as it will result in the most accurate return and the fastest refund. We appreciate your patience as we navigate this tax season together, and we stand ready to assist you in any way we can.”
