Florida residency and the 183-day rule: what snowbirds need to know

Sooner or later, every snowbird hears it over dinner: “Spend 183 days in Florida and you don’t pay state income tax.” It’s one of the most repeated, and most misunderstood, ideas in snowbird life. This guide explains what the rule really is, how Florida residency works, and the questions to take to a tax professional. It’s general information, not advice for your situation.

Why residency matters to snowbirds

Florida’s constitution bars a state tax on the income of natural persons who are residents or citizens of the state. In practical terms, Florida has no state personal income tax. If your northern state taxes income, and most do, the question of which state you legally live in can be worth a great deal of money.

That’s exactly why northern states pay close attention to people who say they’ve moved to Florida. Residency audits of people who say they’ve left are a well-known part of the landscape in states like New York.

Domicile vs. statutory residency: the two ideas you need

Almost all the confusion comes from mixing up two different concepts.

Domicile: your one permanent home

Your domicile is the place you intend to be your permanent home, the place you always mean to return to. You can have several houses but only one domicile at a time.

New York’s tax department puts it this way: your domicile is the place you intend to have as your permanent home, and it doesn’t change until you can show you’ve abandoned your old one and established a new one. The burden of showing the change is on you.

Domicile isn’t decided by a single document or a day count. Tax authorities look at the whole picture, which commonly includes:

• Which home is bigger, more valuable and more lived-in
• Where you spend your time
• Where your most treasured belongings, like family photos and heirlooms, are kept
• Where your doctors, lawyers, banks, clubs and place of worship are
• Where your family and active business ties are

Statutory residency: the day-count test

Statutory residency is a separate rule many northern states use to tax people who are not domiciled there. This is where “183 days” comes from.

New York is the best-known example. Under its definitions, you are a New York resident for income tax purposes if either:

• Your domicile is New York, or
• You maintain a permanent place of abode in New York for substantially all of the year and spend 184 days or more in the state during the tax year (that is, more than 183 days), even if your domicile is somewhere else.

New York City and Yonkers apply the same definitions to their own resident taxes.

Here’s the trap. Plenty of snowbirds think, “As long as I spend fewer than 183 days up north, I’m fine.” That only addresses the statutory-residency test. If New York still considers your domicile to be New York, the day count doesn’t save you: a domiciliary is a resident regardless of how many days they spend there. And if you keep a year-round home there and stay 184 days or more, you can be taxed as a resident even after successfully changing your domicile to Florida.

How days are counted

In New York, any part of a day counts as a full day in the state. Arriving at 11 p.m. counts. A narrow exception exists for passing straight through to catch a flight, but stopping for lunch on the way generally turns it into a New York day.

Other states have their own versions of these rules, with different thresholds and definitions. Don’t assume New York’s rules match yours; check with your state’s tax department or a professional.

What counts as a “permanent place of abode”

New York describes it as a residence suitable for year-round use, whether or not you own it. A place used only for vacations generally doesn’t qualify. Courts have refined the meaning over the years, for example holding that the taxpayer must have a genuine residential interest in the home. These details are fact-specific, which is one more reason to get professional help.

What Florida itself asks of you

Florida doesn’t have a 183-day test for income tax, since it has no personal income tax to apply one to. But if you decide to make Florida your domicile, there are steps that both establish residency and create a paper trail.

The Declaration of Domicile (Fla. Stat. 222.17)

Florida law lets you file a sworn Declaration of Domicile with the clerk of the circuit court in the county where you live. The statement declares that you’re a bona fide Florida resident, gives your Florida address, names where you lived before, and lists any other homes you maintain.

If you keep homes in other states, the statute lets you state that your Florida home is your “predominant and principal home” and that you intend to keep it that way permanently. There is also a lesser-known provision that works in reverse: someone domiciled elsewhere who has a Florida home can file a declaration saying they intend to keep their out-of-state domicile.

In Miami-Dade, the Clerk of the Court’s County Recorder accepts the notarized form in person or by mail. The clerk’s site lists a $10 recording fee plus $3 for a certified copy, and says the recorded document comes back in about four weeks. Check the clerk’s page for current fees and payment rules before you file.

A declaration is evidence of intent. It is not, on its own, proof that you’ve changed your domicile. If the rest of your life still points north, a declaration won’t carry the day in an audit.

Other steps that typically go with it

The state’s motor vehicle agency lists actions that can make you a Florida resident, including registering to vote in Florida, filing for the homestead exemption, enrolling children in public school, taking a job here, and living here for more than six consecutive months. Once you’ve established residency, you’re expected to:

• Get a Florida driver’s license within 30 days
• Get Florida auto insurance (required to title and register your vehicle here)
• Register your vehicles in Florida

People changing domicile commonly also register to vote in Florida, update their estate documents with a Florida attorney, move bank and brokerage addresses, file their federal return from their Florida address, and find local doctors. Each step adds weight. Doing some but not others sends mixed signals.

The homestead exemption, in brief

If you own a Florida home and make it your permanent residence, you may qualify for Florida’s homestead exemption on property taxes.

• Amount: Up to $50,000 off the assessed value. The first $25,000 applies to all property taxes, including school taxes. The second applies to non-school taxes on assessed value above $50,000, and is adjusted yearly for inflation. Miami-Dade’s property appraiser lists the total for 2025 at $50,722.
• Eligibility: You must hold title and the home must be your permanent residence, and you must be a permanent Florida resident, as of January 1 of the tax year.
• Deadline: Apply to the county property appraiser by March 1.
• Save Our Homes: Once a home is homesteaded, increases in its assessed value are capped each year at 3% or the change in the Consumer Price Index, whichever is less.
• Renting it out or ceasing to live there permanently can cost you the exemption.

A change on the ballot

Florida voters decide Amendment 3 in the November 3, 2026 general election. According to county property appraisers’ summaries, it would sharply increase the non-school homestead exemption starting in 2027, with new homesteaders phasing in over several years, while keeping the Save Our Homes cap. It needs 60% of the vote to pass. If you’re thinking about buying and homesteading, check your county property appraiser’s site for the outcome and current figures.

Homestead and your northern state

A homestead application asks whether you claim residency elsewhere, and the appraiser may ask for proof that your out-of-state residency has ended. If you file for Florida homestead while keeping a primary-residence tax break up north, expect questions from one side or both.

Common snowbird scenarios

These are simplified illustrations, not answers for your situation.

• You rent in Miami for three months and keep your house in New Jersey as home. You’re a seasonal visitor. Nothing about your tax residency changes, and you don’t need Florida residency paperwork.
• You want to make Florida home but keep your old house up north. This is the situation that draws audits. Your domicile needs to move convincingly, and if you keep a year-round home in a state with a day-count test, you’ll need careful records of where you spend every day.
• You sell up north and move to Florida full time. Domicile is much easier to show, though your old state may still review your final-year return. Mid-year moves often mean filing part-year returns.
• You’re Canadian. Different rules apply on both sides of the border, including U.S. presence tests and your provincial health coverage limits. Get advice from someone who handles cross-border snowbirds.

Keep good records

If you’re changing domicile or relying on staying under a day count, records are everything. Many snowbirds keep:

• A calendar or log of where they are each day
• Credit card and bank statements showing location
• Phone location history, toll records and travel receipts
• Copies of your declaration of domicile, driver’s license, voter registration and homestead approval

Questions to bring to a tax professional

Look for a CPA or tax attorney who handles residency audits in your current state and understands Florida. Ask:

1. Based on my homes and ties, where is my domicile today?
2. Does my state have a statutory-residency or day-count test, and how does it count days?
3. Would keeping my northern home make me a statutory resident if I stay too long?
4. What should I change, and in what order, to move my domicile convincingly?
5. What records should I keep, and for how long?
6. How will a mid-year move affect my returns for that year?
