The federal government signed the Surface Transportation and Veterans Health Care Choice Improvement Act of 2015 (Section 2006 of PL 114-41) into law on July 31, 2015.  This Act sets new due dates for filing federal partnership and C corporation returns for tax years beginning after December 31, 2015.

The change to the federal due dates will not affect the due dates for the Missouri corporation income tax return and Missouri partnership return as these due dates are governed by Missouri statute.  Per Chapter 143.511 and 143.581, RSMo, the due date for the corporate and partnership returns are on or before the 15th day of the fourth month following the close of the taxable year.

Since Chapter 143.551.1, RSMo, allows for a 6 month extension from the due date, the extended due date for Missouri corporate returns will not change for tax year 2016.  Missouri corporate returns with an extension (state or federal) will have until October 15 as the extended due date.  Beginning in tax year 2016, Missouri partnership returns with an extension will have until October 15 as the extended due date.

The Department will update information about the extended due dates in the instructions for the 2016 Missouri partnership and corporate tax returns.  Information about the extended due dates will also be updated on the “Application for Extension of Time to File” form (Form MO-7004).
