New Partnership and C Corp Filing Deadlines

The Surface Transportation and Veterans Health Care Choice Improvement Act of 2015 restructures the due dates and filing deadlines for partnership and C corporation tax returns beginning with the 2016 tax year.

Once the new rules take effect, partnerships will be required to file their returns by the 15th day of the third month following the close of a tax year. For calendar year partnerships, the due date will be March 15, instead of April 15.  C corporations will have until the 15th day of the fourth month following the close of the tax year to file their returns. For calendar year C corps, this means the due date will be April 15, instead of March 15.

A special rule exempts C corps with fiscal years ending on June 30 from this change until tax years beginning after Dec. 31, 2025. Thus, the filing deadlines for such corporations will remain September 15 until 2026.

The bill also modifies the automatic extension periods for C corporations. Calendar year C corps are provided a five month automatic extension for returns for tax years beginning after December 31, 2015 and ending before January 1, 2026. For fiscal year C corps with tax years ending on dates other than June 30, the length of automatic extensions remains unchanged at six months. For fiscal year C corps with tax years ending on June 30, a special seven month automatic extension applies for tax years beginning after December 31, 2015 and ending before January 1, 2026.
