Thanks for the help! If I understand correctly - when you say it could cost me extra - it's costing me extra given that the NYS tax rate is the HIGHER of the two (NYS higher than MA), so yes, I am forced to pay the higher rate of the two, despite living in MA - but if I've already been paying NYS tax as someone who used to reside their permanently, and now I am switching to a MA residence, what I'm not doing (given the credit I will receive back on the NYS Income Taxes I pay) is paying taxes on anything twice. I'm still paying the higher NYS tax rate, but in the end given the tax credit I would get back, it's not costing me anything more the higher NYS rate. Is that correct?
