Canadian Snowbirds in Florida: The Six-Month Rule Does Not Make You a Resident

Two Rules, Two Systems, One Very Common Confusion

Florida has no state income tax and no state estate or inheritance tax, which is a powerful draw for Canadians who own property here. Establishing Florida domicile is largely a matter of intent supported by action. But for Canadians specifically, two other legal systems run alongside Florida law, and they operate on completely different clocks. Understanding all three is the only way to know where you actually stand.

Meet Doug and Marie

Doug is 66 and Marie is 64. They live in Windsor, Ontario, and they own a condo in Palm Coast that they have used every winter for the past seven years. They love the Flagler County weather, they know their neighbors, and they have heard from at least four different people that there is a "six-month rule" they need to follow. What they cannot get a straight answer on is which six-month rule, which system it belongs to, and what it actually controls. Their situation is a composite used for illustration purposes and does not describe any actual client, but it reflects questions that come up constantly among Canadian buyers along the Volusia and Flagler coast.

System One: U.S. Immigration and the B-2 Visit Limit

When Doug and Marie drive across the border at Windsor-Detroit or fly into Daytona Beach International, they enter the United States as B-2 visitors. Canadian citizens generally do not need a visa for tourism, but they are still admitted under visitor status, and a U.S. Customs and Border Protection officer determines at the port of entry how long they may stay. The standard grant is up to six months, but that number is the officer's call, not a guarantee written into the ticket.

The practical ceiling is six months less a day in any twelve-month period. Staying longer without authorization is an immigration violation, and it can affect future admissibility. This is the "six-month rule" most snowbirds have heard about, and it is a real limit with real consequences.

A separate development is worth noting. Beginning April 11, 2025, Canadians who spend thirty days or more in the United States are subject to a mandatory registration requirement, satisfied through either an I-94 record or Form G-325R. Failure to register can result in fines and potential detention. The registration form does not extend an authorized stay. It simply documents presence. Doug and Marie should be aware of it, but complying with it does not give them any additional immigration status.

A bipartisan bill called the Canadian Snowbird Visa Act was introduced in the U.S. House of Representatives in late April 2025. It would allow eligible Canadians aged 50 and older who own or lease a U.S. residence to stay up to 240 days per year. As of this writing it has not become law, and Doug and Marie should not plan around it until it does.

System Two: U.S. Tax Residency and the Substantial Presence Test

Being present in the United States does not automatically make a foreign national a U.S. tax resident, but it can. The IRS uses the Substantial Presence Test to determine whether a nonresident alien has spent enough time in the country to be treated as a U.S. resident for federal income tax purposes. The formula looks at days in the current year and a weighted fraction of days from the two prior years. If the total reaches a specific threshold, the person is treated as a U.S. tax resident regardless of immigration status and regardless of what any state calls them.

This is why late-season stays carry heightened scrutiny. Someone who extends a Palm Coast visit deep into April or May may push their day count into territory that triggers the Substantial Presence Test for that calendar year. The IRS and DHS engage in data matching, and year-end and early-spring arrivals and departures are exactly where the numbers get tight.

There is a relief valve. A Canadian who meets the Substantial Presence Test but maintains a closer connection to Canada than to the United States may file IRS Form 8840, the Closer Connection Exception Statement for Aliens, to avoid being treated as a U.S. tax resident. The form asks about the location of a permanent home, business ties, family ties, social and community memberships, and the jurisdiction where the person holds a driver's license and votes. It is filed annually and must be filed on time. Missing the deadline eliminates the exception for that year.

For Doug and Marie, the analysis matters a great deal. If they spend five months in Palm Coast each winter and maintain their Windsor home, Canadian bank accounts, Ontario health coverage, Canadian professional memberships, and other ties, they likely have a strong closer-connection case. But they need a cross-border tax advisor to run the numbers and prepare Form 8840 each year, not a guess based on what the neighbor in the next condo did.

System Three: Florida Domicile and What "Florida Resident" Actually Means Here

Florida residency for state-law purposes is about domicile, which means the place a person intends to make their permanent home. Florida has no minimum-days rule for establishing domicile. The 183-day test belongs to other states, particularly Canadian provinces and some U.S. states, that use it to determine whether they can keep taxing a person who claims to have left. Florida does not use it to determine whether someone has arrived.

The actions that demonstrate Florida domicile include recording a Declaration of Domicile with the clerk of court under Florida Statute 222.17, obtaining a Florida driver's license within 30 days of establishing residency, registering vehicles in Florida within 10 days of establishing residency, registering to vote with the county supervisor of elections, and applying for the homestead exemption with the county property appraiser before the March 1 deadline for the applicable tax year.

That last point is critical for Doug and Marie. The homestead exemption under Florida law is available only to persons who hold legal or equitable title to real property in Florida and use it as their permanent residence. A Canadian who is a B-2 visitor, who files Form 8840 to confirm a closer connection to Canada, and who keeps their Windsor home as their permanent residence is almost certainly not eligible for homestead exemption on their Palm Coast condo. Applying for it anyway would be a false declaration on a sworn government form. The property appraiser's office for Flagler County reviews applications carefully, and the consequences of a fraudulent homestead claim include back taxes, penalties, and interest going back years.

A Florida address is not Florida domicile. Owning a condo in Palm Coast, paying Flagler County property taxes, and having a Florida phone number do not make someone a Florida domiciliary. Domicile requires that the person intend Florida to be their one permanent home, abandoning any prior domicile. A person cannot be domiciled in two places at once.

The Canadian Side of the Equation

Canada has its own concern: departure tax. A Canadian who actually becomes a resident of another country for tax purposes is treated by the Canada Revenue Agency as having disposed of most worldwide assets at fair market value on the date of departure. For someone who has held appreciated investments or Canadian real property for decades, this deemed disposition can generate a very large tax bill in the year of departure. It is one of the most significant financial consequences of truly leaving Canada, and it is one reason many snowbirds are careful not to sever their Canadian residency ties even when they spend substantial time in Florida.

This creates an inherent tension. Keeping strong Canadian ties to preserve Canadian tax residency and support a Form 8840 closer-connection argument pulls in exactly the opposite direction from taking the steps needed to establish Florida domicile. The two goals are not always compatible, and trying to claim both simultaneously in different contexts carries serious legal risk.

What This Meant for Doug and Marie

After working through the three systems, Doug and Marie's realistic status is this: they are B-2 visitors who may spend up to approximately six months per year in their Palm Coast condo, subject to the discretion of the CBP officer at each entry. They should be filing Form 8840 annually if their day count approaches the Substantial Presence threshold, and they need a cross-border tax professional to confirm that their Canadian ties are documented well enough to support the closer-connection exception. They are not Florida domiciliaries, and they are not eligible for homestead exemption on the Palm Coast property. Their Palm Coast condo is a second home under Canadian and U.S. tax law, and it is treated accordingly by every agency involved.

They can enjoy Palm Coast, Flagler Beach, and day trips up the coast to Ormond Beach or down through New Smyrna Beach for as long as their authorized stay allows. What they cannot do is treat their winter condo as a permanent home for legal purposes without genuinely abandoning their Canadian domicile, accepting the departure tax consequences, and following through on every Florida domicile step in a way that is consistent across immigration, U.S. tax, Canadian tax, and Florida state law simultaneously.

That is not a reason to avoid owning property in Florida. It is a reason to understand what you own and how you hold it before the questions become urgent.
