- New York applies two independent residency tests: domicile, and statutory residency. Failing either one can make you a New York resident for tax purposes.
- Statutory residency turns on two facts together — maintaining a permanent place of abode in New York and spending more than 183 days there.
- Domicile is about where your true home is, and moving your address is only one of several factors auditors weigh.
- New York audits departures to Florida actively, and the evidence is documentary — day counts, property, family, and where your life is administered.
- Federal law generally prevents New York from taxing your qualified pension and retirement income once you are genuinely a nonresident.
Florida's side of this is simple: no state income tax on anything, and no state estate or inheritance tax. Establishing yourself there takes a checklist and a few afternoons.
New York's side is the whole difficulty. New York does not passively accept a departure, it applies two separate residency tests, and the fact that they are separate is what catches people. You can genuinely change your domicile and still be taxed as a New York resident, because the second test does not care where your home is.
Test one: domicile
Domicile is your true, fixed and permanent home — the place you intend to return to. You have exactly one, and you keep it until you demonstrably establish another.
Changing it is a question of fact, weighed across several categories: where your home is and its relative size and value, where your business or active involvement sits, where you keep the items near and dear to you, where you spend your time, and where your family is. No single item decides it. A Florida address with a larger New York house, New York grandchildren visited monthly, and the family art still on New York walls is a weak claim regardless of the paperwork filed.
Test two: statutory residency — and this is the one that catches people
Entirely separate from domicile. You can be taxed as a New York resident, on all of your income, if both of these are true in a year:
You maintain a permanent place of abode in New York — a dwelling suitable for year-round use that you maintain, which does not require you to own it or live in it much, and you spend more than 183 days in New York — with any part of a day generally counting as a full day, subject to narrow exceptions.
Both together. Neither alone. Which produces the outcome that surprises people most: you can successfully change your domicile to Florida and still be a New York resident for tax purposes, because you kept the apartment and visited too often. The domicile analysis and the day count are different arguments and you have to win both.
The corollary is the cleanest advice on this page: the surest way to defeat statutory residency is to not maintain a place of abode in New York. Selling removes half the test permanently. Keeping it means the day count becomes a documented, year-after-year discipline.
What an audit actually examines
New York residency audits are documentary. The questions are consistent:
Days, with proof. Assertion is not evidence. Credit card records, phone location data, E-ZPass records, flight and rail bookings, and calendar entries are what corroborate a count. Keep a contemporaneous log from day one rather than reconstructing one under examination.
The property. What did you keep, how is it furnished, is it available to you year-round, who else uses it and on what terms.
Where your life is administered. Physicians, dentist, accountant, attorney, banks, safe deposit box, place of worship, clubs, veterinarian. A Florida address with a New York doctor and a New York accountant is a pattern auditors recognise immediately.
Family. Where a spouse lives and where minor children attend school carry substantial weight.
Business connections. Board seats, an office, ongoing consulting — anything that keeps you engaged in New York.
Establishing Florida properly
The Florida-side checklist is straightforward and it is also your evidence. File a Declaration of Domicile with the clerk of the circuit court under Fla. Stat. §222.17. Get a Florida driver's licence and surrender the New York one. Register vehicles and register to vote in Florida — voter registration is heavily weighted in residency disputes. Apply for the homestead exemption by March 1 of the tax year, which reduces property tax and doubles as strong domicile evidence. Move the professional relationships. Re-execute your will, powers of attorney and health care directives under Florida law.
Our full move guide covers the sequencing across the year before, the year of, and the years after. The one-line version: the paperwork is easy and the pattern is what matters.
What New York can and cannot reach after you leave
Qualified retirement income is generally protected. Federal law at 4 U.S.C. §114 bars states from taxing a nonresident's income from qualified pension and retirement plans — which covers most IRA and 401(k) distributions and most pension payments once you are genuinely a nonresident.
Non-qualified deferred compensation is different. Depending on structure and payment schedule, it can remain reachable. Do not assume the protection extends to everything with "deferred" in the name.
New York-source income stays taxable. Rental income from New York property, gains on New York real estate, and compensation for work performed in New York remain New York income regardless of where you live.
The year of the move is split. You will file a part-year resident return allocating income between the two periods, and that return is the document New York reads most carefully.
What the move is actually worth — and how to time it
The recurring saving is your New York-taxable income multiplied by the rate it faced. The large saving is on one-time events, because those are controllable and they concentrate income into a single year.
A Roth conversion is the clearest example: federally taxable either way, but New York takes a share if you convert while still a resident and nothing if you convert after. The same logic applies to annuitizing a contract, starting deferred income, exercising options, or selling a business. Every one of those should sit on the Florida side of the line, and moving them there is worth more than any other single decision in the relocation.
Two annuity-specific checks belong on the list: confirm your carrier is licensed in Florida, and check Florida's guaranty association limit against your premium, because guaranty coverage follows your state of residence rather than where the contract was bought. New York and Florida do not set the same limit.
The mistakes that cost people the move
Keeping the New York apartment and treating the day count as an estimate. Converting or realising income in the year before establishing domicile rather than the year after. Filing the Declaration of Domicile and changing nothing else. Missing the March 1 homestead deadline. And assuming that because Florida asks nothing of you, New York will not either.

Holding an annuity through the move?
Which year income lands in decides what New York can reach. Send the contract and your target move date before you annuitize, exchange, or start income — the sequencing is worth more than the product decision.
