Don't fake it. Start full-time in the middle of the year by establishing your residency in one of the no tax states. You then file a pt-time resident tax form for the prior year with NY and your federal using the new address provided to you. Whatever state you establish your residency in, open bank accounts. Transfer your vehicle registration from NY to that state, buy vehicle insurance, set up bank accounts, register to vote etc. Do all the things you would do if you had bought a real house there. NY would not have any grounds to come after you. New address on everything , social security, medicare, all mail, etc. We use SD and have for 11 years.
