Instructions for Completing Form MO-7004
Who should file a Form MO-7004?
Missouri grants an automatic extension of time to file corporation
income tax to any corporation that has a federal extension. A
federal extension does not extend the due date for Financial Insti-
tution taxes. Form MO-7004 and payment are due on or before
the due date of the return. A copy of Form MO-7004 must be
enclosed with the Missouri return when filed. An approved Form
MO-7004 extends the due date up to 180 days.
You do not need to file an Application for Extension of Time to
File—Corporation Income Tax Return (Form 7004) unless:
• You expect to owe a tax liability for the period.
• You want a Missouri extension but not a federal extension. See
“Note” below for exception.
• You seek a Missouri extension exceeding the federal
automatic extension period. Form MO-7004 must be filed on or
before the end of the federal automatic extension period.
You must complete a separate Form MO-7004 for each return.
Note: You are not re quired to file a Form MO-7004 if:
• You have an approved federal extension. (Enclose a copy of
your federal extension when you file your Missouri return.)
• You do not expect to owe additional tax.
• You anticipate receiving a refund.
An extension of time to file a corporate tax return does not extend
the time for payment of the tax. Unless an extension of time to
pay has been granted, a penalty of 5% and interest is charged
on the part of the total tax which is not paid by the original due
date of the return. The interest rate will be posted on our web
site at: www.dor.mo.gov. Remittance should be made payable
to “Missouri Department of Revenue” and submitted with this
