Minnesota Filing Due Date: Corporation tax returns are due by March 15 — or by the 15th day of the 3rd month following the end of the taxable year (for fiscal year filers).
Extended Deadline with Minnesota Tax Extension: Minnesota offers a 7-month extension, which moves the filing deadline to October 15 (for calendar year filers).
Minnesota Tax Extension Form: Minnesota business extensions are automatic, which means there is no written request or application to submit.
Minnesota Extension Payment Requirement: An extension of time to file is not an extension of time to pay. If you owe Minnesota tax, it must be paid by the original due date, or interest and penalties will be charged. You can make a Minnesota extension payment with Form PV80, or pay electronically using Minnesota’s e-Services portal: https://www.revenue.state.mn.us/make-payment
Minnesota Tax Extension Tip: If you owe zero Minnesota tax (or you fully pay your Minnesota tax balance by the original deadline), you will automatically receive a Minnesota tax extension.
