It works like this:
For 2022, you'll be filing a part-year resident tax return in both MA and NY.
MA can tax all the income you earned while you were an MA resident; NY can tax all the income you earned after you became a resident of NY.
For tax purposes, you become a resident of NY on the day you begin living in NY with the intent of making it your new primary, permanent residence. (Your driver's license is irrelevant in this regard.) Note that NYC imposes its own income tax on NYC residents.
Once you become a NY resident, your new employer should withhold New York taxes only. Once you become a NY resident, your income is no longer taxable by MA unless you physically work within the state of MA.
TurboTax can handle this common situation.
By the way, NY gives you 30 days after you become a resident to obtain a NY driver's license.
