General Instructions
Choose your state from the list below to access detailed instructions for both business and personal tax extensions.
Corporation tax returns are due by April 15 — or by the 15th day of the 4th month following the end of the taxable year (for fiscal year filers).
Missouri provides a 180-day extension for corporations that don’t have a valid Federal tax extension (IRS Form 7004). However, if you have a 6-month Federal extension, you will automatically receive a Missouri tax extension for the same length of time — which moves the Missouri filing deadline to October 15 (for calendar year filers).
To request a Missouri extension, file Form MO-7004 by the original deadline of your return.
An extension of time to file is not an extension of time to pay. If you owe Missouri tax, it must be paid by the original due date, or interest and penalties will apply. You can include your Missouri extension payment with Form MO-7004.
The State of Missouri recognizes the Federal business extension (IRS Form 7004). Therefore, if you have a valid Federal extension, you will automatically be granted a corresponding Missouri extension.
Do not file Form MO-7004 if you have a Federal extension and you owe zero Missouri tax for the taxable year.
