General Instructions

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). If you cannot file by that date, you can get a state tax extension. A Massachusetts personal extension will give you 6 extra months to file, which moves the deadline to October 15.

A tax extension only gives you more time to file, not to pay. 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. If you pay 100% of your tax due by the original deadline, you will automatically receive a Massachusetts tax extension.

The Commonwealth of Massachusetts requires personal extensions to be filed electronically if no payment is being made with the extension request. You are also required to file electronically if you’re making an extension payment of $5,000 or more. To file a personal tax extension online, go to Massachusetts WebFile for Income:

Taxpayers who aren’t required to file their extension electronically can use Form M-4868 (Application for Automatic Six-Month Extension of Time to File Massachusetts Income Tax Return). Submit this form by the original deadline of your return (April 15). Remember that an extension payment for your estimated tax due must accompany Form M-4868 when it’s filed.

NOTE: In certain cases, there is no need to submit a tax extension application at all. The Massachusetts Commissioner of Revenue will grant an automatic 6-month tax extension as long as you meet both of the following requirements:

• You owe zero tax with your Massachusetts return (or are due a tax refund); and

• You’ve paid 100% of your Massachusetts tax liability for that year (through withholding, estimated payments, or credits) by the original deadline of your return
