To file a personal tax extension online, go to Massachusetts WebFile for Income: .us/WebFile/WebForms/AutoExtension You are also required to file electronically if you’re making an extension payment of $5,000 or more. The Commonwealth of Massachusetts requires personal extensions to be filed electronically if no payment is being made with the extension request. If you pay 100% of your tax due by the original deadline, you will automatically receive a Massachusetts tax extension. At least 80% of your total Massachusetts tax liability must be paid by the original deadline (April 15) for your tax extension to be valid. A Massachusetts personal extension will give you 6 extra months to file, which moves the deadline to October 15.Ī tax extension only gives you more time to file, not to pay.

If you cannot file by that date, you can get a state tax extension.

Massachusetts personal income tax returns are due by the 15th day of the 4th month following the close of the tax year (April 15 for calendar year taxpayers).
