Changing Your Domicile to Florida: What States Check
Domicile versus residency, the five factors, the paper trail, and the statutory residency trap
Reviewed by the Fairlight Accounting cross-border tax team — U.S. & Canadian Tax Desks
Changing your domicile to Florida means abandoning your old permanent home and establishing a new one in Florida with the intent to stay. It's what ends your former state's power to tax your worldwide income — but high-tax states audit these moves, weighing where your home, business, time, valued possessions, and family actually are. Paperwork helps; behaviour decides.

Domicile versus residency
| Concept | Meaning |
|---|---|
| Domicile | Your one permanent home — the place you intend to return to; you keep it until you establish a new one |
| Statutory residency | A separate test in many states: a permanent place of abode there plus more than 183 days — taxed as a resident even if domiciled in Florida |
The five factors (New York's audit model — widely followed)
| Factor | What auditors compare |
|---|---|
| Home | Size, value, and use of the Florida home versus the northern one |
| Active business | Where you run or actively manage your business |
| Time | Days in each state — the most scrutinized factor |
| Items near and dear | Where family heirlooms, art, pets, and collections are |
| Family | Where your spouse and minor children live and go to school |
The paper trail
Florida driver's licence and vehicle registration, voter registration (and voting in Florida), a sworn declaration of domicile filed with the clerk of the circuit court under section 222.17, Florida Statutes, homestead exemption, Florida doctors, banks, and professional advisers, will updated to Florida, club memberships moved, and a day log (phone location records and credit card statements are what auditors use).
The trap
Keeping your northern home and spending more than 183 days there makes you a statutory resident regardless of domicile — and in New York any part of a day counts as a day (other states' day-count rules vary).
Frequently asked questions
How do I prove I've moved to Florida?
Move your life: home, time, business, family, and valued possessions — and document it with Florida licences, registrations, and a day log.
Can I keep my house up north?
Yes, but stay well under 184 days there, or you may be a statutory resident.
What is the most audited factor?
Time — where you actually spend your days.
Do I file a return in my old state for the move year?
Yes — a part-year resident return (the part-year guide).
