Cross-Border Tax Accountant in Florida: What Canadians in Miami and South Florida Actually Need

Florida is the single most common landing spot for Canadians leaving Canada, and the reason people give is almost always the same one: no state income tax. That part is true and it’s real money. What it doesn’t do is touch your US federal return, and it doesn’t touch the Canadian departure tax that fires on the way out. A cross-border tax accountant working the Miami and Fort Lauderdale corridor spends most of the job on the two things the “no income tax” headline leaves out: the Canadian exit, and the pile of Florida-specific rules (homestead, domicile, real estate, estate tax) that only apply once you’ve actually stopped being a visitor.

Does Florida’s no income tax mean less tax?

Going forward, usually yes on the state layer, and that’s a narrower win than most people expect. Florida’s constitution caps any state tax on a natural person’s income at whatever the US allows as a credit against it, and in practice that means zero.

“No tax upon estates or inheritances or upon the income of natural persons who are residents or citizens of the state shall be levied by the state, or under its authority, in excess of the aggregate of amounts which may be allowed to be credited upon or deducted from any similar tax levied by the United States or any state.” (Florida Constitution, Article VII, s.5(a))

What that provision doesn’t reach is the federal return. A resident alien is taxed on worldwide income exactly the way a US citizen is, under Treas. Reg. 1.1-1(b), so moving from Ontario or Alberta to Florida changes your state tax bill and leaves your federal 1040 exactly where it was. And the year you actually leave Canada is usually the expensive one, not the quiet one, because that’s the year the departure tax runs on your worldwide unrealized gains. The treaty explainer covers how the two countries divide up taxing rights once you’re filing in both places at once, which most movers are for at least one year.

What is the snowbird-to-resident pipeline?

Most Canadians in South Florida don’t move in one step. They spend a few winters as visitors, buy a place, spend more time in it, and only later make Florida home in a way both governments recognize, and each stage carries a different filing obligation.

Stage	What you’re doing	What it triggers
Visitor, under the day-count limit	Winters in Florida, no property yet	Nothing beyond the ordinary Canadian return, as long as the day count stays low
Snowbird, meeting the US substantial presence test	Enough US days to trip IRC 7701(b)(3)(A)	Form 8840 closer-connection claim, filed every year the count is met
Property owner, still a Canadian resident	Buys a condo, keeps it available year-round	A second permanent home on Form 8840 line 15, plus US estate tax exposure on the property itself
Dual filer	Spends enough time that the US treats them as resident, while Canadian ties haven’t been cut	Both a 1040 and a Canadian return, with the treaty tie-break deciding which country wins for treaty purposes
Departing Canadian	Cuts residential ties for good	The departure tax: deemed disposition of worldwide property, T1161, T1243
Full Florida resident	Domicile established, final Canadian return filed	Federal-only US taxation going forward, plus whatever Florida-specific rules (homestead, estate planning) now apply

Skipping a stage is the most common mistake in this corridor. A retired couple who quietly went from 60 winter days to 200 without ever filing Form 8840 usually finds out only when a bank or a lawyer asks about their US tax residency status, and by then several years of the wrong filing posture have already happened. The snowbird day-count guide has the actual math for the stage most people get wrong first.

What actually establishes Florida domicile?

Buying property gets you a deed. It doesn’t get you a domicile, and the two are decided by completely different tests. Florida domicile is a fact question the county property appraiser and the courts decide by looking at your conduct rather than your closing statement, and the CRA on the Canadian side runs its own separate test that looks at your worldwide ties rather than at any piece of US paperwork at all.

• A Florida driver’s license, with your old province’s license surrendered
• Voter registration, available only to US citizens under Article VI, s.2 of the Florida Constitution
• A declaration of domicile recorded with the county clerk
• The homestead exemption application (Form DR-501), filed by March 1
• Your federal tax return address, your bank statements, and where your kids go to school

None of those five is a Canadian tax test. ITA 250(3) says a person “ordinarily resident” in Canada is still a Canadian resident regardless of what’s on file in Florida, and the CRA’s residency test runs through your worldwide residential ties: your home, your spouse and dependants, your personal property, your social and economic connections. A Canadian who buys a Naples condo, gets a Florida license, and even registers to vote (if they’ve since become a US citizen) can still be a Canadian tax resident if the spouse and the house stayed in Ontario. The order the two tests actually run in, and when the treaty tie-break even gets triggered, is worked in whether you’re still a Canadian tax resident.

Can a snowbird claim the homestead exemption?

No. The homestead exemption is only available to a permanent Florida resident who owns and occupies the home as of January 1, and a snowbird who spends winters there and keeps a primary home in Canada doesn’t clear that bar. For someone who genuinely has made the move, the exemption is worth real money and it comes with a separate, slower-building benefit most people conflate with it.

Piece	What it does	Who qualifies
First $25,000 exemption	Off assessed value, against all levies	Fla. Stat. 196.031(1)(a): permanent residence as of January 1
Second $25,000 exemption	Applies to assessed value between $50,000 and $75,000, against non-school levies only	Same test, Fla. Stat. 196.031(1)(b)
Save Our Homes cap	Limits future assessment growth to the lower of 3% or CPI	Only starts the year AFTER the first homestead year; new homestead property is assessed at just value in year one
Article X, s.4 protection	Shields the homestead from forced sale by most creditors	Applies once the home is your permanent residence, regardless of the ad valorem exemption
Portability	Carries a built-up Save Our Homes discount to a new Florida home	Requires a PRIOR Florida homestead within the last three years; a Canadian home doesn’t count

The application deadline is hard. Section 196.011(1)(a) says failing to apply by March 1 “constitutes a waiver of the exemption privilege for that year,” and there’s no grace period built in for someone who was still mid-move from Canada. The forced-sale protection in Article X, Section 4 of the Florida Constitution is separate from the tax exemption and matters more for estate and creditor planning than for the annual property tax bill, and it’s worth understanding before you decide how to title the property in the first place.

Does departure tax still apply if I move to Florida?

Yes, and it’s usually the single biggest number in the whole move. Ceasing Canadian residence deems you to have sold most of what you own at fair market value, and Florida’s lack of a state income tax has nothing to do with what Canada charges you on the way out.

“Where at any particular time… a taxpayer… ceases… to be resident in Canada, the taxpayer shall be deemed to have disposed… of each property… owned by the taxpayer… immediately before that particular time, for proceeds of disposition equal to the fair market value of the property at that particular time.” (ITA 128.1(4)(b))

Half of the resulting gain is a taxable capital gain under ITA 38(a), and it lands on your final Canadian return. Canadian real property is carved out of the deemed disposition, which is one reason the Ontario house and the Florida condo get treated completely differently in this move. If you’re weighing a security-posting option to defer paying the tax rather than the gain itself, that route runs through Form T1244, and reportable property above $25,000 has to be listed on Form T1161. None of that arithmetic is repeated here; the full mechanics, plus the five carve-outs, are worked in what the departure tax actually catches, the Ontario-specific version of this same move is in moving from Ontario to Florida, and the full sequence of what has to happen, in what order, is the leaving-Canada checklist.

What happens to my RRSP and TFSA after I move?

The RRSP mostly takes care of itself; the TFSA usually needs a decision before you go. Both are excluded from the deemed disposition on departure, but that’s where the similarity ends, because the US treats the two accounts in opposite ways once you’re a US person.

• RRSPs and RRIFs generally get automatic US tax deferral under the treaty, with no annual election required since the IRS eliminated the old Form 8891 filing requirement
• A TFSA has no equivalent US shelter: its income is fully taxable on your US return every year you hold it as a US person, and it can carry foreign trust reporting obligations depending on how it’s set up
• Contribution room lost by collapsing a TFSA before departure doesn’t come back once you’re a non-resident

Most cross-border files that come through the door with an ugly TFSA problem are ones where nobody flagged this before the move, only after. If you’re still working through what your account mix looks like on both sides of the border, what the departure tax actually catches has the full exclusion list, including where pension rights and RRSPs sit on it.

What happens when I sell Florida real estate?

It depends entirely on whether you’re still a foreign person for US tax purposes on the closing date. A full-time Florida resident selling a home that’s genuinely been their main residence can exclude up to $250,000 of gain ($500,000 married filing jointly) under IRC 121; a snowbird or a non-resident seller runs into FIRPTA withholding instead, which is calculated on the sale price, not the gain.

Seller’s status at closing	What applies	The number that matters
Full US resident, home was your main residence 2 of the last 5 years	IRC 121 exclusion	Up to $250,000 single / $500,000 married, on the gain
Still a nonresident alien (snowbird, dual filer pre-departure)	FIRPTA withholding under IRC 1445	15% of the sale price by default, dropping to 10% or nothing depending on the buyer’s own use and the price
Anyone renting the property out before the sale	Depreciation recapture	Ordinary recapture is usually zero on straight-line residential property; the depreciation is still taxed, up to 25%, as unrecaptured section 1250 gain

A Canadian who kept a US rental going through the whole pipeline, from occasional Airbnb to long-term tenant, also has a reporting job on the Canadian side for as long as they’re still a Canadian resident: the property counts toward the $100,000 T1135 cost-amount threshold unless it’s purely personal-use. The full withholding mechanics, the residence-based exceptions to FIRPTA, and the recapture math are worked in the Canadian buying US property guide, and the depreciation and cost-segregation questions specific to a vacation rental are in the FIRPTA vacation rental guide.

What US estate tax exposure comes with Florida?

Real, and often bigger than people expect, because Florida’s own lack of an estate tax has nothing to do with the federal number. A Canadian who’s still a nonresident alien for US purposes gets only a $13,000 credit against US estate tax, which covers a taxable estate of exactly $60,000; a Canadian who’s become a full US domiciliary is taxed like a US citizen, on worldwide assets, but gets the much larger citizen exemption.

“A credit of $13,000 shall be allowed against the tax imposed by section 2101.” (IRC 2102(b)(1))

The treaty changes the nonresident number substantially, if the estate claims it: Article XXIX B(2) of the Canada-US treaty gives a Canadian resident’s estate the greater of the ordinary $13,000 credit and a pro-rated share of the much larger credit a US citizen’s estate gets, but the IRS position is that it has to be claimed on a filed Form 706-NA rather than assumed. That’s a different question from Florida’s own estate tax, which was repealed years ago and adds nothing to this analysis either way. Once you become a full US domiciliary, the federal exemption shifts in your favor, but the Canadian side of the story usually isn’t finished: any Canadian-situs property you still hold gets a deemed disposition on your terminal Canadian return at death, so the estate can face both systems on different assets. The full credit mechanics, the pro-rata fraction, and the filing deadline sit in the $60,000 exemption guide.

Should I use a Florida LLC to hold my Florida property?

Usually not for the reason people think, and it’s worth understanding before you title the deed. A US LLC with a single owner defaults to disregarded status for US tax purposes, which matches owning the property personally, but Canada doesn’t necessarily follow that US default at all.

“Reg 301.7701-3 classifies an entity ‘for federal tax purposes’ and settles nothing about how Canada treats the same LLC.”

The CRA’s long-standing administrative position treats a US LLC as a corporation for Canadian tax purposes regardless of its US disregarded or partnership classification, which creates a hybrid mismatch: the US sees a transparent entity, and Canada sees a foreign corporation. That mismatch can strand foreign tax credits, since the US tax paid isn’t always creditable cleanly against the Canadian tax on the same income when the two countries disagree on who actually earned it, and the mechanics run through the foreign tax credit folio. If a Canadian corporation, rather than an individual, owns the LLC, rental income earned through it can also raise passive foreign-affiliate income questions on the Canadian corporate return, on top of the US classification question. The entity-election mechanics themselves, including the 75-day window and which entities actually qualify to elect, are covered in the check-the-box guide, which is written for a Canadian corporation but explains the same regulation an LLC owner needs to understand before assuming an LLC solves anything.

Do I still report Canadian accounts in Florida?

Yes, for as long as you’re a US person and the accounts exist, and this is the filing people forget fastest once the move feels finished. FinCEN Form 114, the FBAR, is required whenever the aggregate value of your foreign financial accounts, RRSPs and TFSAs included, tops $10,000 at any point in the year, and Form 8938 carries its own separate thresholds depending on your filing status.

• FBAR: aggregate foreign account value over $10,000 at any time in the year, filed with FinCEN, separate from your tax return
• Form 8938: for a US resident filing single, over $50,000 on the last day of the year or over $75,000 at any point; higher thresholds apply filing jointly
• Both forms can be required for the same accounts in the same year; one doesn’t excuse the other

South Florida’s concentration of Canadian and Latin American wealth has made it a genuine focus area for federal offshore-account enforcement for years, which is one more reason not to treat this as paperwork that can wait. The FBAR vs. Form 8938 guide has the full threshold table and the penalty exposure for missing either one.

Does my CPP count toward Social Security?

Yes, through the totalization agreement, and it matters most for someone who moved to Florida mid-career rather than at retirement. The agreement lets your CPP contribution years and your US Social Security quarters be combined to meet the minimum eligibility requirement in either system, even though each country still pays its own benefit based only on the credits earned there.

“The agreement… helps people who have worked in both countries, but who have not worked long enough in one or both countries to qualify for regular social security benefits, to qualify for benefits based on combined, or ‘totalized,’ credits.” (Social Security Administration, Totalization Agreement with Canada)

This is exactly the pattern in the snowbird-to-resident pipeline: someone who worked twenty years in Canada, moved to Florida in their fifties, and worked another decade in the US before retiring often doesn’t have enough US quarters alone for full Social Security eligibility, and doesn’t need to worry about it because the totalization agreement fills the gap. It combines credits for eligibility only; each country still calculates the actual dollar benefit under its own formula. The totalization agreement guide has the mechanics of how the combined-credit calculation actually works.

Does Florida residency stop the Canadian OAS clawback?

No, and this is one of the more common surprises for a retiree who assumes a Florida address changes everything about how Canada taxes their retirement income. The treaty routes ordinary taxation of Canadian social security benefits, OAS included, to your country of residence, so once you’re genuinely a Florida resident it’s the US that taxes the payment itself, rather than Canada. The OAS recovery tax works on a completely separate track.

• The recovery tax (the “clawback”) isn’t an income tax within the meaning of the treaty; it’s a repayment mechanism under the Old Age Security Act
• It’s calculated on your net world income, reported to Canada whether or not you’re a Canadian tax resident
• Moving to Florida changes who taxes the OAS payment; it does nothing to the clawback calculation itself

A retiree with substantial US-source retirement income can be surprised to find the clawback still eating into their OAS cheque exactly as it would if they’d stayed in Toronto, because the mechanism was never about where you live, only about how much you make. The OAS clawback guide works through the treaty provision and the recovery tax calculation side by side, since they run on genuinely different rules and get confused constantly.

What if I sell my Canadian home after moving?

It depends on whether you sell before or after your Canadian residence actually ends, and the two paths lead to very different filings on both sides of the border. Canadian real property is excluded from the departure tax’s deemed disposition, so the house itself doesn’t get valued and taxed on the day you leave; what changes is whether the eventual sale happens as a resident or as a non-resident.

• Sell while still a Canadian resident: reported under the ordinary resident rules, no clearance certificate needed
• Sell after Canadian residence ends: the principal residence exemption stops growing from the departure date forward, a non-resident clearance certificate process kicks in on the Canadian side, and the US side of the same sale runs on entirely separate rules
• Keep it and rent it out instead: a different withholding regime applies to non-resident landlords

Both sides of that same sale, the shrinking Canadian exemption and the US tax consequences of selling a home you no longer live in, are worked together rather than separately in selling the Canadian home after moving to the US, because trying to compute one side without the other is where most of the costly mistakes in this corridor actually happen.

What does a cross-border accountant cost?

Less than the cost of getting the sequencing wrong, and the real work in this corridor is almost always about order rather than any single form. A departure date chosen for the wrong reason can shift the deemed-disposition gain into a worse tax year; an LLC set up before anyone checked the Canadian side can cost more in stranded credit than it saves in liability protection; a homestead application filed a week late waives the whole year.

1. Pin down where you actually sit in the snowbird-to-resident pipeline right now, using the day count and your residential ties rather than the calendar you had in mind.
2. If a departure date is coming, work out what it does to your deemed disposition and your Ontario (or other province) filing before you book anything.
3. Settle the TFSA question before you leave; it’s the one account nobody fixes after the fact without cost.
4. If real estate is involved, decide the ownership vehicle and the FIRPTA-versus-121 question before closing, not after.
5. Once you’re a genuine Florida resident, get the homestead application in by March 1 and start the domicile paper trail deliberately rather than by accident.

The $250 Cross-Border Assessment is built for exactly this moment: a fixed-price, written, CPA-reviewed read on where you sit in the pipeline, what your departure date does to the numbers, and which Florida-specific rule you’re about to trip over, before any of it is filed or closed on.

This guide is general information, not tax advice for your specific situation. Which points apply, and how, depends on your facts.
