Minnesota S Corporation M8 Due Date

Time Calendar

Due Date

File your return and pay the taxes payable as soon as possible after the end of the tax year, but no later than the due date for filing your federal income tax return.

Generally, the due date is:

  • Calendar year returns: March 15 2012
  • Fiscal year returns: the 15th day of the third month after the end of your tax year.

If the due date falls on a weekend or legal holiday, returns and payments electronically made or postmarked on the next business day are considered timely.

Extension of Time to File

All S corporations are granted an automatic six-month extension to file Form M8, if the tax payable for the year is paid by the regular due date.

However, if the IRS grants an extension of time to file your federal return that is longer than the Minnesota automatic six-month extension, your state filing due date is extended to the federal due date.

This is a filing extension only. To avoid penalties, you must make an extension tax payment by the regular due date. See Extension Payment on this page for details.
