Hello,
I am a PA resident. I work remotely for an engineering outfit in MA. 100% of the work is performed in PA. My company withholds tax for MA. I don't set foot in MA, except for the annual Christmas Party. How can I get credit for taxes withheld to MA when filing in PA? Do I have to file as a non-resident in MA, even though I don't live there and none of the work is performed there?
