Am I a resident for Massachusetts state income tax purposes?
Resident status rules
There are two ways to be considered a full-time resident of Massachusetts. The first is to live in Massachusetts for the entire tax year, while the second is to maintain a home in Massachusetts and spend more than 183 days of the tax year in the state.
Part-year resident status rules
Part-year residents refer to individuals who either moved to the state and became residents or moved out of the state and ended their residencies within the tax year.
Nonresident status rules
If neither of the above applies, then an individual is considered a nonresident of Massachusetts. A state tax return is still required if your Massachusetts annual gross income exceeds $8,000 or the prorated personal exemption, whichever is less.
What is Massachusetts' standard deduction?
Unlike other states, Massachusetts does not have a state standard deduction. Instead, state taxpayers can determine if they qualify for certain tax exemptions to reduce the amount of tax owed.
Anyone who files a Massachusetts state tax return is given a personal exemption amount based on their tax filing status. Taxpayers may also be eligible for additional exemptions, such as those for having qualifying dependents or for having paid certain types of medical or dental costs throughout the tax year.

What’s the deadline for filing Massachusetts state income taxes?
The filing deadline for 2023 Massachusetts state income tax returns was April 17, 2024. To have qualified for a six-month extension, you must have paid at least 80% of the total amount of tax owed by that deadline. If you didn't owe any taxes and didn't file by the deadline, an extension to October is automatically granted.
The state extension deadline follows the federal extension deadline set by the IRS, which for the 2023 tax year is Oct. 15, 2024. Keep in mind that being granted a federal tax extension does not grant you a state tax extension in Massachusetts.
Those who have been affected by a federally declared disaster automatically receive an extension for filing tax returns, paying their tax bill and filing a Massachusetts tax extension.

If you missed the deadline to file and didn't apply for an extension, your return is considered late. The state levies both late filing penalties and late payment penalties. Late returns are charged a fee of 1% per month of the tax due, up to a maximum of 25%, plus interest.
