State tax filing

you can't

 

What one might do is to treat the middle state as a "Non-resident" state, taht you really set up a supposed "permanent" Residence/Domicile in.    Then indicate you "Moved" from the first state, to the last state on the date you moved in there.     

 

But the income allocations for the two part-year tax returns get complicated and perhaps a professional outside tax preparer might be advisable this year  (Definitely do that if any of the states moved between were reciprocal tax states, like MD, DC, VA, WV, PA and perhaps a few more surrounding states, depending on which were involved....that gets really complicated)

_________________________________

A simple situation for nonreciprocal tax states.    Lived in MO until April, cleared out stuff and went to NE to live/work from May-Sept, then picked up your stuff, and went to KS to live/work for the remainder of the year and plan to remain there for the foreseeable future.

 

That would be a KS resident at the end of the year, "moved" from MO to KS in Sept, and time in NE was temporary as a nonresident and you didn't really take up permanent residence there.

_______________________________
OF course, this is just one situation, and your details could change what you do to file.  For instance, in the "simple" situation above, perhaps you are only in KS temporarily, and had established a permanent residence/domicile in NE , along with Drivers's Lisc. car registered, Banking, register to vote etc., and plan to return there after the temporary job in KS (usually, less than 6 months)....then the move would be from MO to NE, and just travelling temporarily to KS as non-resident. 

 

Messy...so the details can be important.
