Qualifying Widow(er) with Dependent Child
If your spouse dies during the tax year, and you and your spouse had a Massachusetts taxable year that began on the same day, you may file married filing jointly for the tax year in which your spouse dies. Since Massachusetts doesn't have a filing status equivalent to the federal qualifying widow(er) with dependent child, you can file as head of household for 2 years after the year your spouse died. If you don't meet the head of household requirements in the 2 subsequent years, you would file as single.
