State of Massachusetts
Personal Income Tax Extensions
Modified 2019 Tax Return Due Date: July 15, 2020
Massachusetts Filing Due Date: State personal income tax returns are due by April 15 — or by the 15th day of the 4th month following the end of the taxable year (for fiscal year filers).
Extended Deadline with Massachusetts Tax Extension: Massachusetts offers a 6-month extension, which moves the filing deadline from April 15 to October 15 (for calendar year filers).
Massachusetts Tax Extension Form: If you aren’t making a payment with your state extension, you are required to electronically file your request. Additionally, taxpayers who need to make a payment of $5,000 or more must file their Massachusetts extension electronically. Your extension request should be submitted online using Massachusetts WebFile for Income: wfb.dor.state.ma.us/WebFile/Extension
If you aren’t subject to the electronic filing requirement, you can request a Massachusetts extension by submitting Form M-4868 on or before the original due date of your return. Remember to include payment for your Massachusetts tax with Form M-4868, if applicable.
Massachusetts Extension Payment Requirement: An extension of time to file does not give you more time to pay your Massachusetts income tax. All state tax payments are due by the original deadline of the return. Any tax not paid by the proper due date will be subject to interest and penalties. As long as you pay 80% of your Massachusetts tax liability by April 15, your Massachusetts extension will be valid.
Massachusetts Tax Extension Tips: You will automatically be granted a Massachusetts extension if 100% of your Massachusetts tax liability is paid by the original due date (April 15).
If you owe zero Massachusetts income tax for the taxable year, or you’re due a state tax refund, you can get a Massachusetts extension without having to file anything with the state.
