What are the Florida residency rules for high net worth individuals?

The same as for everyone, applied with more scrutiny. Florida itself only asks that you establish domicile: a permanent Florida home and the intent to stay, evidenced by a Declaration of Domicile, homestead, license and registrations. The real test comes from your former state, which looks at where your home, business involvement, time, family and treasured possessions are, and at your day count if you kept a home there. Higher incomes make an audit more likely, so the evidence has to be consistent and contemporaneous.

Can I use tax returns as proof of Florida residency?

Partly. A federal return filed from a Florida address, and a part-year or nonresident return in your old state, are consistent with a move and auditors check them. They are your own statements, though, so they do not prove residency on their own. Florida's driver license office does not list a tax return as proof of address; it accepts items such as a deed, mortgage or lease, Florida voter card, Florida vehicle registration, recent utility bills, and employer documents like a W-2, 1099 or pay stub. For tax residency, pair your returns with a Declaration of Domicile, homestead and a day-by-day record of where you were.

How many days do I need to spend in Florida to be a resident?

Florida sets no minimum because it has no income tax to enforce. The days that matter are in the state you left: stay under its statutory-resident line if you keep a home there, and spend more of the year in Florida than anywhere else, because your old state will compare the two.

What is a Florida Declaration of Domicile?

A sworn statement filed with the clerk of the circuit court in the county where you live, under section 222.17 of the Florida Statutes. It declares that you are a bona fide resident of Florida and lists where you live, where you came from, and any other homes you keep. It is optional and does not make you a Floridian by itself, but it is dated, sworn and public evidence of intent.

Do I need to sell my home in New York or another high-tax state?

Not necessarily, but keeping it changes the math. With a permanent place of abode in New York for substantially all of the year, 184 or more New York days makes you a statutory resident taxed on worldwide income, whatever your domicile. Keeping the old home also weighs against you in the domicile analysis, so the day record and the rest of your evidence must be stronger.

Can my old state audit me after I move to Florida?

Yes. High-income movers from New York, California, New Jersey, Connecticut and Massachusetts are frequent audit targets. Auditors use questionnaires, travel and card records, phone data and property records to rebuild your year. A contemporaneous day-by-day record is far easier to defend than a reconstruction.

Florida Residency Rules for High Net Worth Movers

Quinn Moran · April 26, 2026

The short answer

Florida has no income tax and no day-count test, so for a high net worth mover the Florida rules are about domicile: a real Florida home, a sworn Declaration of Domicile under s. 222.17, homestead exemption, a Florida license, voter and vehicle registration, and your life visibly centred in Florida. The rules that decide your tax bill belong to the state you left, which will test whether your domicile really changed and, if you keep a home there, whether you crossed its statutory-resident day line (184 days in New York, more than 183 in New Jersey, Connecticut and Massachusetts). Wealthier movers are audited on the details: where the home, business, time, family and valuables actually are.

Florida Residency Rules for High Net Worth Movers

High net worth movers ask about "Florida residency rules" as if Florida runs the test. It mostly does not. Florida has no personal income tax, so it has no residency test to enforce and no day count. The rules that decide whether you owe tax are your former state's: its domicile test, and its statutory-resident day count if you keep a home there.

That is why wealthier movers lose these cases. Not because they skipped a Florida form, but because the old state could show their life never really moved. This guide covers what Florida asks for, what the old state tests, and what counts as proof.

The rules in one table

Question	Who decides	What decides it
Are you a Florida domiciliary?	Your conduct, evidenced by Florida filings	A real Florida home plus the intent to stay; Declaration of Domicile, homestead, license, registrations
Did you abandon your old domicile?	Your former state	Where your home, business, time, family and valuables are
Are you a statutory resident of the old state anyway?	Your former state	A permanent place of abode there plus a day count over its line
Which state gets the estate?	The state of domicile at death	The same domicile evidence, read by your heirs' auditors

The Florida residency guide has the full state-level rules and sources. The Florida has no day count post explains the two tallies your old state runs. The Florida residency proof checklist lists the documents each agency accepts.

Florida's side: establishing domicile

Florida asks for one thing: that Florida is your permanent home. You show it with steps that leave dated public records:

Declaration of Domicile. Under s. 222.17, Florida Statutes, anyone who has established domicile in Florida may file a sworn statement with the clerk of the circuit court in their county, showing that they reside in and maintain a place of abode there and declaring that they are "a bona fide resident of the state". It also lists your former home and any other homes you keep. It is optional, cheap and sworn, and it belongs in your file. See how to file by county.
Homestead exemption. Up to $50,000 off the assessed value of your permanent residence, plus the Save Our Homes cap on assessment growth. You must own the home and make it your permanent residence as of January 1, and apply to the county property appraiser by March 1 (Form DR-501). See the Florida Department of Revenue and our post on the homestead January 1 deadline.
Florida driver license, vehicle registration and voter registration, surrendering or cancelling the old state's. Florida sets short deadlines for new residents, so do these first.
Addresses everywhere: your federal return (IRS Form 8822 for the change of address), brokerage and bank accounts, insurance, and your employer's records.
Estate documents redrafted under Florida law. Florida has no estate or inheritance tax, which is why domicile at death matters as much as domicile at filing time; see the estate tax domicile trap.

Our step-by-step Florida residency checklist covers the order to do these in.

The old state's side: what high net worth movers are tested on

Domicile: the life audit

You keep your old domicile until you both abandon it and establish a new one, and the burden of proof is on you. New York's Nonresident Audit Guidelines weigh five primary factors, which other states echo:

Home: the size, value and use of the Florida home compared with the one you left.
Active business involvement: whether you still run or actively manage a business from the old state.
Time: where you spent the year, which is a day count by another name.
Items "near and dear": where the art, heirlooms, family photos and safe-deposit contents went.
Family: where your spouse and minor children live and go to school.

For high net worth movers, factors 2 and 4 are where cases turn. Keeping an office and a board seat in Manhattan while the art stays on the walls in Greenwich says more than any Florida filing. Our leaving New York guide goes through each factor.

Statutory residency: the day line

If you keep a home in the old state, a day count can make you a resident there even if Florida is your domicile:

Former state	Statutory-resident test	Source
New York	Permanent place of abode for substantially all of the year and 184 or more days; any part of a day counts	NY DTF; NY guide
New Jersey	Permanent home and more than 183 days	NJ guide
Connecticut	Permanent place of abode all year and more than 183 days; any part of a day counts	CT guide
Massachusetts	Permanent place of abode and more than 183 days; any part of a day counts	MA guide
California	No day line; more than 9 months creates a presumption of residency, and the FTB weighs closest connections	CA guide
Illinois	No day line; domicile and temporary-or-transitory purpose	IL guide

A statutory resident is taxed on worldwide income, which for a high net worth mover means investment income, gains and carried interest, not just wages. The line is a cliff, not a slope: the day that crosses it costs the whole year.

What counts as a day

New York's own guidance: "Any part of a day is a day for this purpose, and you do not need to be present at the permanent place of abode for the day to count as a day in New York" (NY DTF). A late landing at JFK, a lunch meeting in Midtown, or a drive through to the old house all count. That is why a margin below the line matters, and why the count needs to be kept as you go rather than rebuilt from receipts.

What counts as proof of Florida residency

For a DMV, proof is two documents with your Florida address (deed, mortgage or lease, voter card, vehicle registration, recent utility or insurance bills, or a W-2, 1099 or pay stub, per FLHSMV). For a residency audit, proof is a file:

Florida filings: Declaration of Domicile, homestead, license, voter and vehicle registration
Consistent returns: a federal return from your Florida address, and a part-year or nonresident return in the old state for the move year
The five factors moved: home, business, time, near-and-dear items, family
A contemporaneous day record showing where you were each day, ideally with Florida comfortably ahead and the old state well under its line

Tax returns help only as part of that file. They are your statements; the day record and the public filings are what corroborate them. Our guide to what counts as proof of residency compares the documents different agencies accept.

The snowbird pattern auditors look for

The highest-risk profile is the snowbird who keeps the northern home: winters in Palm Beach, summers in the Hamptons or Westchester, and a day count that drifts toward the line in a busy year. Auditors know the pattern. They pull card statements, toll and travel records and phone data to rebuild the year, and a gap in your own record is filled with their version of it.

The defence is boring and effective: keep the old-state count well under its line, check it monthly rather than in December, and keep the record as you go. See the snowbird's guide to dual-state residency for the calendar side.

Where iReside fits

iReside keeps the day record for you. It counts your days automatically in the background on your iPhone, by state and by country, with nothing to log by hand.
