Relocating to Miami: The Florida Tax and Domicile Guide for 2026

Last verified: July 2, 2026 against Tax Foundation rate tables, Florida Department of Revenue exemption rules, and New York statutory-residency definitions.

Every serious wave of Miami luxury demand since 2020 has had a tax story behind it. Fund managers leaving Manhattan, founders leaving San Francisco, families moving domicile ahead of a liquidity event. The savings can run six or seven figures a year. The move can also fail completely if you treat it as a change of address instead of a change of domicile, because New York and California audit exactly this. This guide covers the real math, the 183-day rule, the filings that establish Florida domicile, what homestead and Save Our Homes are worth over a decade, and the honest carrying costs on the Miami side of the ledger.

The Math: What a High Earner Actually Saves

Florida's constitution prohibits a personal state income tax, so the rate is 0 percent on wages, capital gains, and retirement income. California's top marginal rate is 13.3 percent, the highest in the country, and California taxes capital gains as ordinary income. New York State tops out at 10.9 percent, and New York City residents pay up to another 3.876 percent in city income tax on top, per the Tax Foundation. Your federal bill does not change when you move. The state layer is the entire prize.

Household income	CA top-rate exposure (13.3%)	NY top-rate exposure (10.9% + NYC 3.876%)	FL (0%)	Indicative annual difference
$1,000,000	$133,000	$147,760	$0	$133,000 to $147,760
$5,000,000	$665,000	$738,800	$0	$665,000 to $738,800
$10,000,000	$1,330,000	$1,477,600	$0	$1,330,000 to $1,477,600

Read the table honestly: this applies the top marginal rate for illustration. Effective savings depend on your income composition, deductions, where the income is sourced, and how much actually sits in the top bracket. New York's 10.9 percent bracket, for example, only starts at $25 million of income; a $1 million earner faces lower marginal rates. Confirm your own number with a CPA before you move. The direction of the math does not change: recurring, state-level, and large. I covered the California side of this migration in my California wealth-tax and Miami migration analysis.

The 183-Day Rule and What New York and California Actually Audit

Here is what most people get backwards: the 183-day rule is not a Florida requirement. It is the weapon your old state uses to keep taxing you. New York applies a statutory-residency test: if you maintain a permanent place of abode in New York and spend more than 183 days of the year there, New York taxes you as a full resident on all your income, even if your domicile is legally Florida, per the New York State Department of Taxation and Finance. Keeping the Manhattan apartment as a pied-a-terre is the classic trap; I broke down how that plays out for Miami buyers in my NYC pied-a-terre tax analysis.

The day counting is stricter than people assume. Any part of a day spent in New York generally counts as a full New York day for the 183-day test, with narrow travel exceptions, per the state's own nonresident filing guidance. Residency auditors reconstruct your calendar from cell-phone location records, credit card activity, toll and swipe data, and travel logs. If your records are vague, the auditor's version of your year wins. A contemporaneous day log is not paranoia, it is the whole defense.

California plays a different game. There is no bright-line day count; the Franchise Tax Board weighs where your closest connections sit: your home, your spouse and children, the school your kids attend, your doctors, your business ties, and where you spend your time. California also presumes anyone in the state for more than nine months of the year is a resident. And both states keep taxing income sourced there after you leave: wages for days worked in the state, and rent from a New York or California property, stay taxable to that state no matter where you live.

How to Establish Florida Domicile, Step by Step

Domicile is intent proven by actions. Florida gives you a paper trail designed for exactly this, and the whole package costs less than a dinner at a Brickell steakhouse. In order:

1. File a Declaration of Domicile. A short sworn statement recorded with the clerk of the circuit court in your county under Florida Statute 222.17. In Miami-Dade you file it with the Miami-Dade Clerk of the Court for a small recording fee. It is the formal opening move of your residency file.
2. Get a Florida driver license within 30 days. New residents have 30 days after establishing residency to swap their license, per the Florida Department of Highway Safety and Motor Vehicles. Retitle, register, and insure your vehicles in Florida at the same time.
3. Register to vote in Florida and cancel your old registration. Then actually vote here. Few documents read cleaner in an audit file.
4. File for the homestead exemption by March 1. Own and occupy your Miami home as your permanent residence on January 1, then file with the Miami-Dade Property Appraiser by March 1. This is both a tax break and a loud declaration that this home is your primary residence.
5. Move your center of life. Primary doctors, dentists, accountants, estate attorney, the bank branch that knows you, club memberships, safe deposit box, and where your kids go to school. Auditors weigh where your life actually happens, and they read these items line by line.
6. Keep a day log. 183 or more days in Florida, fewer than 183 in your old state, with flight records and receipts that prove it. The savings table above is only yours if this row of the file holds.

Homestead Exemption and Save Our Homes: What Ten Years Looks Like

Once Florida is home, two property-tax mechanics start working for you. First, the homestead exemption: up to $50,000 comes off your assessed value, with the first $25,000 applying to all levies and the second $25,000 to non-school levies, per the Florida Department of Revenue. On a luxury purchase the exemption itself is modest money. The second mechanic is not.

Save Our Homes caps the annual increase in your homesteaded property's assessed value at 3 percent or the change in CPI, whichever is lower. Miami luxury values have appreciated faster than 3 percent in most recent years, and every dollar of market value above your capped assessed value is untaxed. Run a simple illustration: a home assessed at $2 million grows to roughly $2.69 million of assessed value after ten years of maximum 3 percent increases. If the market took its value meaningfully higher, the entire gap compounds in your favor, year after year. Florida sweetens it further with portability: move within the state and you can transfer up to $500,000 of that accumulated benefit to the next homestead. Voters also approved indexing the second $25,000 exemption to inflation starting in 2025, which I covered in my homestead exemption update for Miami buyers.

What Miami Costs Going the Other Way

I will not sell you a fantasy: part of the income-tax win gets handed back in carrying costs, and buyers who skip this math end up surprised. Property tax comes first. Millage rates across Miami-Dade municipalities stack city, county, and school levies to roughly 2 percent of assessed value, and a new purchase resets the assessment at market value; Save Our Homes only starts protecting you after you own and homestead the property. On a $4 million condo that is real annual money from day one.

Then insurance and HOA. Florida coastal insurance is among the most expensive in the country, and luxury condo association fees now carry post-Surfside structural-reserve funding, so budgets at older towers have climbed. I keep the current numbers in my true cost of owning a Miami luxury condo guide and my Miami condo insurance guide; read both before you set a budget. The honest framing: for a household with $1 million or more of annual income, the recurring state-tax savings usually dwarf the added carrying costs. Below that, the math tightens, and the right answer depends on the specific building's fees, insurance, and assessment history.

Where Relocating Buyers Actually Land

Relocation buyers cluster where the commute to a Miami office is short and the product is new. Brickell takes the largest share: the St. Regis Residences Miami and Cipriani Residences draw finance relocators who want to walk to the office district, and Mercedes-Benz Places is pulling the design-driven crowd. Downtown's bayfront answer is the Waldorf Astoria Residences. Families gravitate to Coconut Grove for the school cluster and canopy streets. Edgewater is the value play on the water, with the Edition Residences leading the branded wave there.

My Advice on Tax-Driven Moves

When a New York or California client asks me whether the savings are real, my answer is yes, and then I make them run the carrying costs before they celebrate. HOA, insurance, property tax on a full-market assessment, and any pending special assessment decide whether a specific building keeps the tax win or quietly eats a chunk of it. That is the number I push hardest on, because it is the one relocation buyers skip most.

My second piece of advice: win the audit with boring paperwork before you shop for views. The Declaration of Domicile, the license swap, the homestead filing, and a clean day log cost almost nothing and take a few weeks. I have watched buyers spend months debating a floor plan and zero minutes on the residency file that protects six figures a year. Do it in the other order. And when you do pick the building, this is a two-speed market: trophy waterfront is holding price while generic mid-tier has softened, so I look at the specific developer, floor, and line before I ever talk about the savings being "invested" in the unit.

"The tax math sells itself. My job on a relocation is the other half: making sure the domicile file is airtight and the building's carrying costs don't quietly hand the savings back."Gerardo Gonzalez, Licensed Real Estate Agent at Compass

Frequently Asked Questions

How long do I have to live in Florida to be a resident?

Florida itself sets no minimum day count for domicile; it looks at intent plus actions like a Declaration of Domicile, a Florida driver license, and a homestead filing. The 183-day figure matters because high-tax states use it against you: New York taxes anyone who keeps a permanent place of abode there and spends more than 183 days in the state as a full resident. Most advisors have you spend at least 183 days a year in Florida and keep records proving it.

Does Florida have state income tax?

No. Florida levies 0% personal state income tax, and its constitution prohibits one. Wages, capital gains, and retirement income face no state-level income tax here, versus a 13.3% top rate in California and 10.9% in New York State plus 3.876% for New York City residents.

What is the Save Our Homes cap?

Save Our Homes caps the annual increase in the assessed value of a homesteaded Florida property at 3% or the change in CPI, whichever is lower. In a market appreciating faster than 3%, the gap between market value and capped assessed value compounds every year, and that entire gap goes untaxed. Moving within Florida lets you transfer up to $500,000 of that benefit through portability.

Can New York still tax me after I move?

Yes, in two ways. If you keep a permanent place of abode in New York and spend more than 183 days there, New York taxes you as a statutory resident on all your income, even with a Florida domicile. And income sourced to New York, like wages for days worked there or New York rental income, stays taxable to New York regardless of where you live.

What documents establish Florida domicile?

Start with a Declaration of Domicile recorded with your county clerk under Florida Statute 222.17. Then a Florida driver license, which new residents must obtain within 30 days, Florida voter registration, and a homestead exemption filing by March 1. Auditors also weigh where your doctors, accountants, banks, vehicles, and club memberships sit, so move those too.
