Ok that makes sense. I was getting tripped up with the verbiage of "MA sourced income". Which essentially would mean if you are physically at a company in the state of MA it would be sourced there. If you are considered a remote employee, your income source is the state you currently live in.
For deductions, would I also split the FICA withholdings between the two states? The MA state return asks me to allocate the 'non-MA portion' of FICA.
