The TFSA/FHSA Trap for Canadian-American Dual Citizens: Why Canada's "Tax-Free" Accounts Aren't Tax-Free for You

A cross-border tax expert explains how Canada's most popular savings accounts can quietly create a U.S. tax and penalty nightmare for dual citizens — and what to do about it.

Why does this matter if you hold a U.S. passport and a Canadian account

If you're a Canadian-American dual citizen, a Canadian bank or financial advisor almost certainly suggested you open a TFSA (Tax-Free Savings Account) or, more recently, an FHSA (First Home Savings Account). On the Canadian side, the advice is sound — these are excellent, genuinely tax-free vehicles for Canadian tax purposes.

Here's what your Canadian advisor probably didn't tell you: the United States does not recognize either account as tax-free. And because the U.S. taxes its citizens on worldwide income no matter where they live, the "tax-free" account that helps you in Canada can quietly create annual U.S. tax, brutal information-reporting requirements, and penalties that can dwarf any benefit the account ever provided.

I'm Tetiana Voita, EA, CAA — a federally licensed Enrolled Agent and IRS Certifying Acceptance Agent who works with cross-border and dual-citizen clients. This is the single most common, and most expensive, mistake I see Canadian-American dual citizens make. Let's walk through the TFSA/FHSA trap so you can avoid it — or clean it up.

Quick answer: are TFSA and FHSA taxable in the U.S.?

Yes. For a U.S. person (citizen or green-card holder), income earned inside a TFSA or FHSA — interest, dividends, and capital gains — is fully taxable on your U.S. return every year, even though Canada treats it as tax-free. Unlike an RRSP, neither account is protected by the U.S.-Canada tax treaty. On top of the tax, these accounts can trigger foreign-trust reporting (Forms 3520 and 3520-A), PFIC reporting (Form 8621), FBAR, and Form 8938 — each with its own penalties. For many dual citizens, the compliance cost alone exceeds the Canadian tax savings.

Why are TFSA and FHSA tax-free in Canada but not in the United States

The U.S. tax system is one of only a couple in the world that taxes based on citizenship, not residence. If you hold U.S. citizenship — even if you've lived in Canada your whole life and have never filed a U.S. return — you are a "U.S. person" required to report your worldwide income to the IRS.

Canada created the TFSA and FHSA as domestic incentives. The U.S. simply never agreed to honor them. The U.S.-Canada Income Tax Treaty protects some Canadian accounts — most notably the RRSP — but the TFSA and FHSA are not on that list. So while Canada waves the income through tax-free, the IRS sees ordinary taxable income.

This is the heart of the TFSA/FHSA trap for Canadian-American dual citizens: an account that is a smart move for a Canadian-only taxpayer becomes a liability the moment U.S. citizenship enters the picture.

Trap #1: Annual U.S. tax with no treaty shield

Inside your TFSA or FHSA, you might earn interest, dividends, or capital gains. In Canada, none of it is taxed. In the U.S.:

• Interest and dividends are taxed as ordinary income each year.

• Realized capital gains are taxed in the year realized.

• There is no deferral and no exemption — because the treaty's tax-deferral provisions (Article XVIII) cover retirement accounts like RRSPs, not general-purpose or home-savings accounts.

You may be able to claim foreign tax credits for Canadian tax you paid — but here's the cruel irony: because Canada charges zero tax on these accounts, there is often no Canadian tax to credit against the U.S. tax. You end up paying U.S. tax on income that was supposed to be tax-free, with nothing to offset it.

Trap #2: The foreign trust problem — Forms 3520 and 3520-A

This is where the real damage usually happens.

The IRS frequently treats a TFSA — and very likely an FHSA — as a foreign grantor trust under IRC §§671–679, because the account is established under foreign law with a U.S. person as both grantor and beneficiary. If that classification applies, you may be required to file:

• Form 3520 — Annual Return to Report Transactions With Foreign Trusts, and

• Form 3520-A — Annual Information Return of a Foreign Trust With a U.S. Owner.

The penalties for missing these are among the harshest in the tax code: generally, the greater of $10,000 or 35% of the contributions/distributions for Form 3520, plus separate penalties for a late or missing 3520-A. These are per form, per year.

There is some relief — but read carefully. Revenue Procedure 2020-17 exempts certain "tax-favored foreign trusts" from Forms 3520 and 3520-A. RESPs and RDSPs generally qualify because they exist for education or disability purposes. TFSAs generally do not qualify, because they're general-purpose savings accounts with no specific qualifying purpose. The FHSA, despite its specific home-purchase purpose, also does not fit the narrow categories the IRS exempted (which are limited to medical, disability, educational, and retirement purposes) — so it likely gets no relief either.

And note the most important limitation: Rev. Proc. 2020-17 only removes the reporting requirement. It does nothing to change the taxation. The income is still taxable even when the form is excused.

Trap #3: PFIC and Form 8621 — the worst regime in the tax code

Most people don't hold cash in their TFSA or FHSA — they hold investments. And if those investments are Canadian mutual funds or ETFs, you've stepped on the most punishing landmine in the entire U.S. tax code: the PFIC (Passive Foreign Investment Company) rules.

Nearly every Canadian mutual fund and pooled fund is a PFIC for U.S. purposes. Each one generally requires its own Form 8621 every year. Under the default PFIC tax regime:

• Gains and certain distributions are taxed at the highest ordinary income rate, not capital-gains rates.

• An interest charge is added for the deferral period.

• The reporting is so complex that preparation fees for even a handful of funds can run into the thousands.

There's one more sting: failing to file a required Form 8621 can keep your entire U.S. tax return open to IRS audit indefinitely — the statute of limitations doesn't start running until the form is filed.

Trap #4: FBAR and Form 8938 stack on top

As if the above weren't enough, your TFSA and FHSA are also foreign financial accounts, which means two more disclosures may apply:

• FBAR (FinCEN Form 114): required if the combined value of all your foreign accounts exceeds $10,000 at any point in the year. Willful failure penalties can reach the greater of $100,000 or 50% of the account balance.

• Form 8938 (FATCA): required when your specified foreign assets exceed the thresholds — generally $50,000/$75,000 for U.S. residents and $200,000/$300,000 for single filers living abroad (doubled for joint filers). For the 2025 tax year, Form 8938 is due with your Form 1040 by April 15, 2026.

These are information forms — but the penalties for ignoring them are real, and they apply on top of everything else.

The FHSA specifically: newer, and arguably riskier

The First Home Savings Account launched in Canada in 2023, so it's still new — and that's exactly why it's dangerous. There is even less IRS guidance on the FHSA than on the TFSA, and almost no published planning consensus.

What we do know:

• The FHSA is tax-deductible going in and tax-free coming out for Canadian purposes only.

• For U.S. purposes, the deduction is not recognized, the growth is taxable, and the account is not treaty-protected.

• It carries the same foreign-trust and PFIC exposure as the TFSA.

The cross-border tax community's near-unanimous guidance for U.S.-Canada dual citizens is blunt: if you're a U.S. person, don't open an FHSA. And if you already have one, get cross-border advice before you contribute another dollar.

What is not a trap: RRSP and RESP

It's important to be fair — this isn't "every Canadian account is bad." Two common accounts are genuinely manageable for dual citizens:

• RRSP (Registered Retirement Savings Plan): Protected under Article XVIII(7) of the U.S.-Canada treaty. You can defer U.S. tax on the growth, mirroring the Canadian treatment. The RRSP is the cross-border-friendly account.

• RESP (Registered Education Savings Plan) and RDSP: Generally exempt from Forms 3520/3520-A under Rev. Proc. 2020-17, because they serve qualifying education/disability purposes (though PFIC issues can still apply to investments inside them).

The distinction matters: the trap is specific to TFSA and FHSA, not to Canadian registered accounts as a whole.

What the TFSA/FHSA trap actually costs

Consider a dual citizen with a $60,000 TFSA invested in two Canadian equity mutual funds, earning roughly $3,000 a year in dividends and gains.

• Canada: $0 tax. Perfect.

• United States: the $3,000 is taxable income; the two funds are PFICs requiring two Forms 8621; the account may require Forms 3520 and 3520-A; and it must be listed on the FBAR and possibly Form 8938.

The actual U.S. tax on $3,000 might be a few hundred dollars, but the professional preparation cost of doing the PFIC and foreign-trust forms correctly can easily run $1,500–$4,000 per year. In other words, the account "saves" you nothing and costs you thousands. That's the trap in one sentence: you pay more to comply than the account ever saves you.

What to do if you already hold a TFSA or FHSA

Don't panic, and don't close anything in a hurry — a poorly timed move can create a taxable event or a missed-filing penalty. Instead:

1. Get a cross-border review of exactly what's inside the account (cash vs. PFIC funds changes everything).

2. Quantify the cost vs. benefit — sometimes the cleanest answer is to wind the account down deliberately.

3. Check whether you've under-reported in prior years. If so, the IRS offers paths back into compliance — most notably the Streamlined Filing Compliance Procedures for non-willful taxpayers, which can waive penalties when used correctly.

4. Coordinate the U.S. and Canadian sides so you don't fix one country's problem by creating another's.

The worst thing you can do is keep contributing on autopilot because a Canadian advisor — who doesn't prepare U.S. returns — told you it was "tax-free."

The cross-border angle for dual citizens in the NJ/NY area

Many of my clients are dual citizens living in the New Jersey/New York metro who still hold accounts opened during years in Canada, or who keep them open, thinking they'll move back. If that's you, remember: your U.S. state of residence taxes your worldwide income too, so New Jersey or New York will generally tax that same TFSA/FHSA income on top of the federal return. Cross-border planning isn't just a federal exercise — it follows you to your state return.

Don't let a "tax-free" account cost you. Let's review it together.

The TFSA/FHSA trap is one of the most misunderstood issues in cross-border taxation — and one of the most fixable, when you catch it early. Whether you already hold one of these accounts, you're being pressured to open one, or you've never filed the foreign forms, and you're worried, the smartest first step is a conversation with someone who works both sides of the border.
