My employer withheld Massachusetts state tax when i lived, and worked in New Hampshire. Do i need to file for MA and how would I get the state tax back?

If you never lived in or worked in MA during the tax year, and you had no other MA-source income (such as rental income from a property located in MA), then you would file a non-resident MA tax return, showing zero MA income, in order to have the incorrectly withheld taxes refunded to you.
