Massachusetts Part-Year Resident - Income Taxed by Another State
I have moved to Massachusetts in March of last year and I worked remotely for a NY employer. Previously I lived in NJ, so I am filing 3 state tax returns. However, Massachusetts seems to be the most complicated of them all. My W2 only shows NY taxes, even after I moved. I am confused as to what does "Income Taxed by Another State" section means and it includes language about "Enter the total 5% Income Taxed by Other States while you were a part-year resident of Massachusetts" and "Enter the Income Tax Paid on This Income to Other States while you were a part-year resident of Massachusetts". Can someone help and explain what should be entered?
Thank you!
