What is the deadline for filing taxes in Missouri?

The deadline for filing taxes in Missouri is generally April 15th. However, if April 15th falls on a weekend or holiday, the deadline is extended to the next business day. It is important to note that taxpayers can request an extension to file their state income tax return, but not for paying any taxes owed. The extension allows an additional six months, making the new deadline October 15th. To avoid penalties and interest, the full payment of taxes owed must be submitted by the original due date of April 15th. Taxpayers who are unable to pay their entire tax liability can apply for a payment plan to settle their outstanding balance over time.
