My husband and I moved from Massachusetts to Tennessee at different times. He moved 2/15/19 and took the entire household with him.  I continued to work and live in Mass in temporary housing until 8/31/19. For the MASS return what should we put as our part year: 1/1/19-2/15/19 or 1/1/19-8/31/19?  Does it matter?  We know how much income we made while living in each state.
