You opened your TFSA at the bank when you moved to Canada. Your coworkers all had one. The advisor said it was free money — tax-free growth, tax-free withdrawals, no reporting. And for Canadians, that is entirely true. But you are not just Canadian. You are a US citizen, a green card holder, or a US person — and the IRS does not recognize the Tax-Free Savings Account as tax-free. Not even close. In fact, the TFSA may be the single most punishing Canadian account type for Americans to hold, carrying potential penalties that can reach 35% of the gross value of the account every single year you fail to report it. That is not a typo. Thirty-five percent. Per year.
The Penalty Stack: What You Could Owe the IRS
- Form 3520 penalty: 35% of the gross value of the TFSA — per year of non-filing
- Form 3520-A penalty: 5% of the gross value of the TFSA — per year of non-filing
- FBAR penalty (non-willful): $10,000 per year of non-filing
- FBAR penalty (willful): Greater of $100,000 or 50% of account balance — per year
- Form 8938 penalty: $10,000 per year, escalating to $50,000
- Income tax on all growth: Dividends, interest, and capital gains inside the TFSA are fully taxable on your US return — every year
- PFIC penalties: If you hold Canadian mutual funds or ETFs inside your TFSA, the IRS taxes them at the highest marginal rate plus an interest charge
Let that sink in. A Canadian who opens a TFSA pays zero tax. An American who opens the same TFSA and fails to report it can face penalties that exceed the account balance within two to three years. This is not a theoretical risk. The IRS has assessed these penalties. Cross-border tax professionals see these cases every month. And the problem is getting worse as the TFSA contribution room grows — the lifetime maximum is now $109,000 for anyone who was 18 or older in 2009 and has lived in Canada continuously (with the 2026 annual limit at $7,000).
Why the IRS Does Not Recognize Your TFSA
The core problem is structural. The US-Canada Tax Treaty — the same treaty that protects your RRSP from US taxation through Article XVIII — contains no equivalent provision for the TFSA. The TFSA was created in 2009, decades after the Treaty was last substantially revised. Canada and the United States have never amended the Treaty to include TFSA protection.
Without treaty protection, the IRS applies its default classification rules. Under IRC Sections 671 through 679, your TFSA is classified as a foreign grantor trust. Here is why:
- You (the US person) are the settlor — you contributed the funds
- You are the beneficiary — you receive the income and can withdraw at any time
- The account is held at a Canadian financial institution — a foreign entity
- You retain complete control over the investment decisions and withdrawals
This foreign grantor trust classification triggers a cascade of reporting obligations that do not apply to RRSPs (which are covered by the Treaty) and do not apply to Canadians (who have no US filing obligations). The classification also means that all income earned inside the TFSA — every dollar of interest, every dividend payment, every capital gain — is taxable on your US return in the year it is earned. The "tax-free" in Tax-Free Savings Account is a Canadian concept. The IRS has never agreed to it.
The 4 Forms You Must File for Your TFSA
Holding a TFSA as a US person triggers up to four separate annual reporting obligations, each with its own penalty regime. Missing any one of them is a violation. Missing all of them — which is what happens when nobody tells you — creates compounding penalty exposure that can dwarf the account balance.
1. FinCEN Form 114 (FBAR) — Foreign Bank Account Report
Your TFSA is a foreign financial account for FBAR purposes. If the aggregate maximum value of all your foreign accounts — TFSA, RRSP, bank accounts, investment accounts — exceeds USD $10,000 at any point during the year, you must file the FBAR electronically through the BSA E-Filing System.
- Deadline: April 15, with automatic extension to October 15
- Non-willful penalty: Up to $10,000 per annual report (per Bittner v. United States, 2023)
- Willful penalty: Greater of ~$148,000 (inflation-adjusted for 2026) or 50% of account balance per account per year
- Criminal penalty: Up to 5 years imprisonment for willful non-filing under 31 U.S.C. Section 5322
2. Form 8938 (FATCA) — Statement of Specified Foreign Financial Assets
Under IRC Section 6038D, if your total specified foreign financial assets exceed the applicable threshold, you must report your TFSA on Form 8938 attached to your Form 1040. For US persons living abroad, the thresholds are $200,000 on the last day of the year or $300,000 at any point during the year.
- Deadline: Filed with your Form 1040 (April 15, or October 15 with extension)
- Penalty: $10,000 for failure to file, escalating by $10,000 for each 30-day period of continued non-compliance after IRS notification, up to $50,000
- Additional penalty: 40% accuracy-related penalty on any understatement of tax attributable to undisclosed foreign financial assets under IRC Section 6662(j)
3. Forms 3520 and 3520-A — Foreign Trust Reporting
This is where the TFSA penalty math becomes devastating. Because the IRS classifies the TFSA as a foreign grantor trust, two trust-specific forms are triggered:
Form 3520 (Annual Return to Report Transactions With Foreign Trusts) must be filed by the US person who is the owner of or beneficiary of the foreign trust. For a TFSA, that is you. The penalty for failure to file Form 3520 with respect to a foreign grantor trust is 35% of the gross reportable amount — which is the gross value of the portion of the trust attributable to you. For a TFSA worth $85,000, that is a $29,750 penalty. Per year.
Form 3520-A (Annual Information Return of Foreign Trust With a US Owner) is technically the trust's return — but since the TFSA "trust" does not have a US tax advisor and will not file this form on its own, the obligation falls to you as the US owner. The penalty for failure to file Form 3520-A is 5% of the gross value of the trust assets treated as owned by the US person. For the same $85,000 TFSA, that is $4,250 per year.
Combined Form 3520/3520-A penalties alone: 40% of the TFSA value per year of non-filing.
Critical Detail:
Unlike income tax penalties that are based on tax owed, the Form 3520 and 3520-A penalties are based on the gross value of the trust — not on any unpaid tax. Even if you owe zero additional US tax on your TFSA income (because of Foreign Tax Credits or low income), the information return penalties apply in full. The IRS does not care that you had no tax liability. The penalty is for not filing the form.
4. Form 8621 — The PFIC Trap Inside the Trap
If your TFSA holds Canadian mutual funds, Canadian-listed ETFs, or other pooled investment vehicles, each one is almost certainly classified as a Passive Foreign Investment Company (PFIC) under IRC Sections 1291 through 1298. This triggers Form 8621 (Information Return by a Shareholder of a Passive Foreign Investment Company or Qualified Electing Fund) for each PFIC holding, each year.
The PFIC tax regime is widely considered the most punitive section of the Internal Revenue Code for individual taxpayers. Under the default "Section 1291 excess distribution" method:
- Gains and "excess distributions" from the PFIC are allocated ratably over your entire holding period
- Each prior year's allocation is taxed at the highest marginal tax rate in effect for that year — currently 37% for ordinary income — regardless of your actual tax bracket
- An interest charge is added on top of the tax, calculated as if you had owed the tax in each prior year and were paying it late
- You cannot use the preferential long-term capital gains rate (20%) or qualified dividend rate (20%) — PFIC income is always taxed as ordinary income at the maximum rate
The result: a Canadian ETF that earned 8% annually inside your TFSA might face an effective US tax rate of 50% or more once the interest charge is layered on top of the maximum-rate tax. And because the TFSA is also a foreign trust, you get no treaty protection, no capital gains rate, and no deferral.
Form 8621 itself carries a penalty of $10,000 per failure to file under IRC Section 6038D cross-reference provisions. But the real cost is the punitive tax calculation, not the filing penalty.
Real Scenario: What This Looks Like in Dollars
Sarah's TFSA: A Case Study
Sarah is a US citizen who moved to Toronto in 2015. She opened a TFSA at her bank and has been maximizing contributions every year. By January 2026, her TFSA holds $85,000 CAD (approximately $62,000 USD), invested in a mix of Canadian equity mutual funds and a Canadian bond ETF.
Sarah has never reported her TFSA on her US tax return. She did not know she had to — her Canadian bank certainly did not mention it, and her Canadian accountant does not handle US returns. She has been filing US returns each year through an online service, but answered "No" to the foreign accounts question on Schedule B because she thought TFSAs were like Roth IRAs.
Sarah's potential penalty exposure for the 2025 tax year alone:
- Form 3520 penalty: 35% x $62,000 = $21,700
- Form 3520-A penalty: 5% x $62,000 = $3,100
- FBAR non-willful penalty: $10,000
- Form 8938 penalty (if above threshold): $10,000
- PFIC tax on mutual fund gains (estimated on $5,000 annual growth): $2,500+ (at 37% + interest charge)
- Regular income tax on TFSA earnings: $1,200+
Total potential exposure for ONE year: $48,500+
Sarah has not filed for 10 years (2015-2025). Even using only the non-willful penalty amounts and accounting for lower balances in earlier years, her cumulative penalty exposure exceeds $200,000 — more than double the current value of her TFSA.
The account that was supposed to be "tax-free" now carries penalties worth 3x the account balance.
Sarah's case is not unusual. We see variations of this story monthly at Zenith. The details change — the balance might be $40,000 or $150,000, the investments might be GICs or mutual funds — but the pattern is the same: a well-meaning American who opened a TFSA because everyone in Canada has one, never reported it because nobody told them to, and now faces a penalty stack that seems absurd relative to the account size.
The TFSA vs. RRSP: Why the Treaty Matters
Americans in Canada frequently ask why the RRSP gets treaty protection and the TFSA does not. The answer is timing and structure:
- The RRSP existed when the Treaty was negotiated. Article XVIII of the US-Canada Tax Treaty specifically addresses "pensions" and "retirement" arrangements, and Revenue Procedure 2014-55 formalized the RRSP deferral election. The RRSP has been part of the Treaty framework for decades.
- The TFSA was created in 2009. The Treaty has not been amended to include it. Despite years of advocacy by cross-border tax professionals and dual citizens, neither government has prioritized a TFSA protocol to the Treaty.
- The TFSA has no US equivalent. While some practitioners compare it to a Roth IRA, the TFSA has no earned-income requirement, no age restriction, and unlimited withdrawal flexibility — it does not fit neatly into any IRC category that would allow the IRS to grant it favorable treatment by analogy.
The practical effect: your RRSP can sit quietly in Canada, growing tax-deferred on both sides of the border (with the treaty election), while your TFSA — even a small one — generates annual US reporting obligations across four different forms and exposes you to five-figure penalties for each year of non-compliance.
Is a TFSA a Foreign Trust? The IRS Says Yes — Here Is Why
This is the foundational question that drives every TFSA reporting obligation for Americans in Canada. The IRS has never issued formal published guidance — no Revenue Ruling, no Revenue Procedure, no Notice — specifically classifying the TFSA as a foreign trust. Yet the legal analysis under existing IRC provisions leads overwhelmingly to that conclusion, and the vast majority of cross-border tax practitioners file on that basis.
Under Treasury Regulation Section 301.7701-4(a), a trust exists for federal tax purposes when a person (the trustee) holds legal title to property for the benefit of another person (the beneficiary). The IRS applies this standard broadly. When you open a TFSA at a Canadian financial institution, the institution holds the assets in trust — in fact, most TFSA agreements use the words "arrangement in trust" or "declaration of trust" in the account documentation. The Canada Income Tax Act itself defines a TFSA as a trust in subsection 146.2(1).
Under IRC Sections 671 through 679, a foreign trust with a US owner is classified as a foreign grantor trust if:
- The trust was created outside the United States (a Canadian financial institution is the trustee)
- A US person is the grantor — you contributed the funds (IRC Section 679(a)(1))
- The trust has a US beneficiary — you can withdraw at any time (IRC Section 679(c))
- The US person retains effective control over the trust assets — you choose the investments and can collapse the account at will
All four criteria are met by a TFSA held by a US citizen or green card holder. The classification triggers:
- Form 3520 — annual return reporting transactions with a foreign trust (IRC Section 6048)
- Form 3520-A — annual information return of the foreign trust itself (IRC Section 6048(b))
- All trust income taxed currently to the US grantor under the grantor trust rules (IRC Section 671)
The Counterargument — and Why Most Practitioners Still File
Some tax professionals argue that a TFSA is a custodial account, not a trust, because the account holder retains direct control over investment decisions and can transfer assets between institutions — characteristics more consistent with a brokerage account than a trust. They point to Revenue Ruling 2004-86 and the "business purpose" test under Treas. Reg. Section 301.7701-4(a), arguing that a TFSA lacks a separate business purpose beyond personal savings.
This argument has found success at IRS Appeals in individual cases. However, it remains a minority position. The statutory penalties for failing to file Forms 3520 and 3520-A — 35% and 5% of gross trust value, respectively — are so severe that the conservative approach of filing dominates professional practice. Until the IRS issues definitive guidance, the risk-reward calculation strongly favors treating the TFSA as a foreign trust and filing accordingly.
TFSA Form 3520 and 3520-A: What to File and When
Forms 3520 and 3520-A are the most consequential — and most confusing — part of TFSA reporting. Here is exactly what each form requires, when it is due, and what happens if you miss it.
Form 3520: Annual Return to Report Transactions With Foreign Trusts
Who files: You, the US person who is the owner or beneficiary of the TFSA.
What it reports: Contributions to the TFSA during the year, distributions received, and the gross value of the trust attributable to you. For a TFSA, you report both your annual contribution (up to $7,000 CAD for 2026) and any withdrawals.
Deadline: April 15 (same as your Form 1040). If you file Form 4868 for a tax return extension, Form 3520 automatically extends with it. US citizens and residents living abroad get the automatic 2-month extension to June 15, and can further extend to October 15.
Penalty for failure to file: Under IRC Section 6677(a), the penalty is the greater of $10,000 or 35% of the gross reportable amount. For a TFSA, the gross reportable amount is the gross value of the trust attributable to you. There is no de minimis exception — even a $5,000 TFSA triggers the $10,000 minimum penalty.
Form 3520-A: Annual Information Return of Foreign Trust With a US Owner
Who files: Technically, the foreign trust (your TFSA) is required to file this form. In practice, your Canadian bank will never file it — they have no US tax obligation and no awareness of this requirement. The responsibility falls to you as the US owner under IRC Section 6048(b).
What it reports: The trust's income statement (interest, dividends, capital gains earned inside the TFSA), balance sheet (assets held at year-end), and a Foreign Grantor Trust Owner Statement (which you attach to your Form 1040).
Deadline: March 15 — this is 3.5 months after the calendar year-end of the trust. A 6-month extension is available by filing Form 7004 by March 15, extending the deadline to September 15.
Penalty for failure to file: Under IRC Section 6677(b), the penalty is the greater of $10,000 or 5% of the gross value of the trust assets treated as owned by the US person.
Revenue Procedure 2020-17: A Potential Exemption
In 2020, the IRS issued Rev. Proc. 2020-17, which exempts certain Canadian tax-favored accounts from Forms 3520 and 3520-A filing. The exemption applies to accounts that meet four criteria: (1) the account receives tax-favored treatment under Canadian law, (2) the account is reported annually to the CRA, (3) contributions do not exceed limits prescribed by Canadian law, and (4) withdrawals are conditioned on the account's purpose.
RESPs and RDSPs clearly qualify. However, the TFSA's status under Rev. Proc. 2020-17 is debated. The TFSA meets criteria 1, 2, and 3 — but criterion 4 is problematic because TFSA withdrawals have no restrictions and no required purpose. You can withdraw for any reason at any time. Some practitioners argue this disqualifies the TFSA from the exemption. Others argue the withdrawal flexibility does not matter because the TFSA otherwise meets the spirit of the provision.
Until the IRS clarifies, most conservative practitioners continue to file Forms 3520 and 3520-A for TFSAs. If your tax advisor takes the position that Rev. Proc. 2020-17 exempts your TFSA, ensure they document the reasoning in your file in case of IRS inquiry.
How to Report Your TFSA on a US Tax Return: Step-by-Step
If you hold a TFSA and are a US person, here is the complete step-by-step process for reporting it correctly on your US tax return. This covers the 2025 tax year (filed in 2026).
Step 1: Gather Your TFSA Documentation
Collect the following from your Canadian financial institution before you begin:
- Year-end TFSA account statement showing the maximum account value during the year (needed for FBAR)
- Year-end balance in Canadian dollars (needed for Form 8938 and Forms 3520/3520-A)
- Interest earned during the year
- Dividends received (distinguish between eligible dividends and other dividends for Canadian purposes — but all are ordinary income for US purposes)
- Capital gains or losses realized from sales of investments inside the TFSA
- Contributions made during the year and total contributions to date
- Any withdrawals made during the year
- If you hold Canadian mutual funds or ETFs: the fund's annual distribution details and NAV at year-end
Step 2: Convert All Amounts to US Dollars
The IRS requires all amounts in USD. Use the annual average exchange rate published by the IRS for income items, and the year-end spot rate for balance reporting (FBAR, Form 8938). For 2025, the IRS publishes these rates on its Yearly Average Currency Exchange Rates page. As a practical matter, many practitioners use the Bank of Canada annual average rate.
Step 3: Report TFSA Income on Form 1040
All income earned inside the TFSA is taxable on your US return in the year earned — the Canadian tax-free treatment does not apply for US purposes.
- Interest income: Report on Schedule B, Part I. Enter as foreign-source interest (no 1099-INT will be issued by a Canadian bank)
- Dividends: Report on Schedule B, Part II. Canadian dividends are generally ordinary dividends for US purposes (not qualified dividends, because the TFSA is a foreign trust and the trust — not you — is the technical recipient)
- Capital gains: Report on Schedule D and Form 8949. Use the USD-converted proceeds and cost basis
- Answer "Yes" to Schedule B, Part III, Question 7a — you have a financial interest in a foreign financial account
Foreign Tax Credits: Because the TFSA is tax-free in Canada, you paid zero Canadian tax on this income. That means you have no foreign tax to claim as a credit on Form 1116. You pay the full US tax with no offset. This is the TFSA catch-22.
Step 4: File FinCEN Form 114 (FBAR)
If the aggregate maximum value of all your foreign financial accounts — TFSA, RRSP, bank accounts, investment accounts — exceeded USD $10,000 at any point during the year, file the FBAR electronically through the BSA E-Filing System at bsaefiling.fincen.treas.gov. Report each foreign account separately, including the TFSA. The FBAR is not filed with your tax return — it is a separate FinCEN filing. Deadline: April 15 with automatic extension to October 15 (no form needed for the extension).
Step 5: File Form 8938 (FATCA) If Thresholds Are Met
If your total specified foreign financial assets exceed the reporting threshold, attach Form 8938 to your Form 1040. For US persons living abroad (filing single), the threshold is $200,000 on the last day of the year or $300,000 at any point during the year. For married filing jointly abroad, it is $400,000 on the last day or $600,000 at any point. Report your TFSA as a "Financial Account" in Part I of Form 8938.
Step 6: File Form 3520 (Foreign Trust Report)
Attach Form 3520 to your Form 1040 filing. Report your TFSA contributions in Part II (Transactions with Foreign Grantor Trusts) and any distributions in Part III. Include the gross value of the trust assets attributable to you. The form is due with your 1040 and extends with it.
Step 7: File Form 3520-A (Foreign Trust Information Return)
This is filed separately — not attached to your 1040. It is due March 15 (with a 6-month extension available via Form 7004). You must prepare this yourself because your Canadian bank will not do it. Attach the Foreign Grantor Trust Owner Statement (page 4 of Form 3520-A) to your Form 1040. This statement shows the trust income that flows through to you as the grantor.
Step 8: File Form 8621 for Each PFIC (If Applicable)
If your TFSA holds Canadian mutual funds or Canadian-listed ETFs, file a separate Form 8621 for each fund. You must determine whether to use the default Section 1291 method (punitive), the Qualified Electing Fund (QEF) election, or the Mark-to-Market election. Most Canadian funds do not provide the PFIC Annual Information Statement needed for a QEF election, so the default method or mark-to-market often applies. Attach each Form 8621 to your Form 1040.
