Hello Jack,

I've double checked my data entry and everything appears to be correct.

In both the Part-Year and Non-Resident the California taxable income is what is shown on the CA W-2 and not the additional income from other sources.

What's confusing me is why Massachusetts goes tax liability goes up as a Full Year Resident vs Part-Year Resident, with everything else staying the same. Feels like I'm double counting income somewhere or perhaps not getting the full credit for income tax paid to CA?
