Bill C-3 Tax Traps: What Americans Claiming Canadian Citizenship Need to Know Before Moving to Canada

On December 15, 2025, Bill C-3 — the Citizenship Act Amendment — came into force and removed the first-generation limit on Canadian citizenship by descent. Overnight, anyone with a Canadian parent or grandparent born in Canada became eligible for Canadian citizenship, regardless of how many generations had passed since the family left Canada. The response has been extraordinary: 56,300+ Americans applied in the first five months, applications are running at 12,000+ per month, and estimates suggest over 3 million Americans may qualify. Every major media outlet has covered who qualifies and how to apply. But there is a massive blind spot in the coverage: not a single article explains what happens to your US tax obligations once you become a dual citizen living in Canada. This guide fills that gap. If you are an American claiming Canadian citizenship under Bill C-3 and considering a move north, these seven tax traps could cost you tens of thousands of dollars — and the Canada Revenue Agency will not warn you about any of them.

Bill C-3: What Changed and Who Qualifies

Before December 15, 2025, Canadian citizenship by descent was limited to the first generation born outside Canada. If your parent was born in Canada but you were born in the US, you could claim citizenship. But if your grandparent was the one born in Canada and your parent was born in the US, you were out of luck — the first-generation limit cut you off.

Bill C-3 eliminated that cutoff entirely. The key eligibility requirements are now:

• You have a Canadian parent or grandparent who was born in Canada (or who was naturalized as a Canadian citizen before your parent's birth)
• There is no generational limit — second generation, third generation, and beyond can now qualify
• You were born after February 14, 1977 (for most cases) or meet specific criteria for those born earlier
• Your Canadian ancestor must have been a Canadian citizen at the time of the next generation's birth

The application process is straightforward — proof of the Canadian ancestor's birth or citizenship, proof of the generational chain, and standard identity documents. Processing times are currently running 6-12 months due to volume. But here is what Immigration, Refugees and Citizenship Canada (IRCC) does not include in its application materials: a single word about the US tax consequences of becoming a dual citizen.

7 Tax Traps at a Glance

Before we dive into the details, here is a quick-reference table of every major tax trap awaiting Americans who claim Canadian citizenship and move to Canada. Save this — you will need it.

Now let us walk through each trap in detail — with specific dollar amounts, form numbers, and the exact steps you need to take to avoid them.

Trap 1: The TFSA Foreign Trust Trap

The Tax-Free Savings Account is Canada's most popular savings vehicle. In 2026, every Canadian resident aged 18+ can contribute $7,000 per year (the limit was $6,500 in prior years), and all investment growth inside the TFSA — interest, dividends, capital gains — is completely tax-free for Canadian purposes. The CRA will encourage you to open one. Your Canadian bank will push one on you. Your Canadian friends will tell you it is a no-brainer. For American citizens, it is a tax nightmare.

The IRS does not recognize the TFSA as a tax-exempt account. Instead, the IRS treats the TFSA as a foreign grantor trust under IRC Sections 671-679. This classification triggers three separate consequences:

• All growth is currently taxable: Every dollar of interest, dividends, and capital gains earned inside your TFSA must be reported as current-year income on your US return — even though you have not withdrawn it and it is tax-free in Canada
• Form 3520-A (Annual Information Return of Foreign Trust): Due March 15 each year for the prior tax year. This form reports the trust's income, distributions, and balance. Penalty for failure to file: the greater of $10,000 or 5% of the gross value of the trust assets for each year of non-compliance
• Form 3520 (Annual Return to Report Transactions with Foreign Trusts): Due with your 1040 (April 15 or June 15 with automatic extension). Reports your contributions and distributions. Penalty for failure to file: the greater of $10,000 or 35% of the gross amount transferred to or received from the trust

Let us put real numbers on this. Suppose you contribute $6,500 per year to a TFSA for 10 years and invest in a diversified portfolio earning 7% annually. After 10 years, your TFSA holds approximately $88,000 — of which about $23,000 is investment growth. Under Canadian tax law, that $23,000 is tax-free. Under US tax law, you have been required to report that growth as income every year and pay US tax on it. But the real danger is not the tax on growth — it is the penalties for not filing Forms 3520 and 3520-A.

If you did not know about these filing requirements and skipped the forms for those 10 years, the penalty exposure is staggering. At a minimum, that is 10 years x $10,000 = $100,000 in Form 3520-A penalties alone, plus additional penalties for each missed Form 3520. In practice, the IRS has assessed penalties of $15,000-$20,000 or more on TFSAs that grew to $88,000 — and that is after reasonable cause abatement. Before abatement, the statutory penalties can exceed the value of the account itself.

The CRA will not tell you any of this. IRCC will not mention it in your citizenship application materials. Your Canadian bank will not flag it when you open the account. This is the single most common trap for Americans who become Canadian dual citizens, and it is entirely avoidable: do not open a TFSA if you are a US citizen.

Trap 2: The PFIC Trap — Canadian Mutual Funds and ETFs

This is the trap that catches the most Americans off guard, because it applies to investments that seem perfectly normal in Canada. Under IRC Section 1297, a Passive Foreign Investment Company (PFIC) is any foreign corporation where either (a) 75% or more of gross income is passive income, or (b) 50% or more of assets produce or are held to produce passive income. Virtually every Canadian mutual fund and most Canadian-domiciled ETFs meet this definition.

Why does this matter? Because PFICs are subject to one of the most punitive tax regimes in the entire Internal Revenue Code. Under the default "excess distribution" regime of IRC Section 1291, here is what happens when you sell a Canadian mutual fund or receive a distribution that exceeds 125% of the average distributions over the prior three years:

1. The gain or excess distribution is allocated ratably over your entire holding period for the PFIC
2. The portion allocated to prior years is taxed at the highest marginal rate in effect for each of those prior years — currently 37% for ordinary income — regardless of your actual income in those years
3. An interest charge is added for the deemed underpayment of tax in each prior year, as if you had owed the tax all along
4. Only the portion allocated to the current year is taxed at your normal rate

The combined effect of the highest-rate taxation plus the interest charge can produce effective tax rates of 50% or higher on gains from Canadian mutual funds. Compare that to the 0%/15%/20% long-term capital gains rates that would apply to equivalent US-domiciled funds. A $100,000 gain on a Canadian mutual fund held for 10 years could generate $50,000+ in US tax, whereas the same gain on a comparable US ETF would generate approximately $15,000-$20,000.

You must file Form 8621 for each PFIC you own — and that means each Canadian mutual fund or ETF gets its own form. If your Canadian financial advisor put you into a balanced portfolio with six Canadian funds, you file six Forms 8621. At $500-$1,000 per form in preparation costs with a cross-border accountant, the compliance cost alone is $3,000-$6,000 per year just for PFIC reporting — on top of your regular tax preparation.

The PFIC trap applies even inside an RRSP. While the US-Canada Tax Treaty defers the tax on RRSP growth, if the RRSP holds Canadian mutual funds, each fund is still a PFIC and still requires Form 8621 reporting. The treaty deferral protects you from current taxation of the growth, but the PFIC classification follows the investment regardless of the account wrapper. When you eventually withdraw from the RRSP, the PFIC rules determine how the gain portion is taxed — and the excess distribution regime can apply.

Trap 3: FBAR Reporting — The $10,000 Trap

If you move to Canada, virtually every financial account you open — chequing, savings, TFSA, RRSP, RESP, non-registered investment, business account — is a "foreign financial account" in the eyes of FinCEN (the Financial Crimes Enforcement Network). Under the Bank Secrecy Act (31 USC 5314), any US person who has a financial interest in or signature authority over foreign accounts with an aggregate maximum value exceeding $10,000 at any point during the calendar year must file FinCEN Form 114, the Report of Foreign Bank and Financial Accounts (FBAR).

For an American living in Canada, the $10,000 threshold is almost immediately exceeded. A single chequing account at RBC or TD with a normal balance triggers the obligation — and once triggered, every foreign account must be reported, even those with tiny balances. You report the maximum balance each account reached during the year, not the year-end balance. Joint accounts with a Canadian spouse are reported at full value, not half.

The penalties for FBAR non-compliance are among the most severe in US tax law:

• Non-willful violation: Up to $10,000 per violation. After the Supreme Court's 2023 Bittner v. United States decision, non-willful penalties are assessed per annual report (not per account), capping exposure at $10,000/year for non-willful filers
• Willful violation: The greater of $100,000 or 50% of the account balance at the time of the violation — per account, per year. If the IRS can show you knew about the requirement and deliberately did not file, this is the penalty regime. Checking "No" on Schedule B's foreign account question while holding Canadian accounts is strong evidence of willfulness
• Criminal penalties: In extreme cases, willful failure to file an FBAR can result in criminal prosecution under 31 USC 5322, with penalties up to $250,000 and five years in prison

The FBAR is filed separately from your tax return — it goes to FinCEN, not the IRS, and is filed electronically at BSA E-Filing (bsaefiling.fincen.treas.gov). The deadline is April 15 with an automatic extension to October 15 (no form needed for the extension). This is not the same as your tax return — it is a separate filing requirement with its own deadlines and penalties.

Trap 4: FATCA / Form 8938 — The Other Foreign Account Report

Yes, there are two separate foreign account reporting requirements, and they go to different agencies with different thresholds and different penalties. Many Americans assume that filing the FBAR covers everything. It does not.

Under the Foreign Account Tax Compliance Act (FATCA), codified at IRC Section 6038D, US taxpayers must file Form 8938 (Statement of Specified Foreign Financial Assets) with their annual tax return if their foreign financial assets exceed specified thresholds. For US citizens living abroad (which you become once you move to Canada), the thresholds are higher than for domestic filers:

• Unmarried / Married filing separately: Total value exceeds $200,000 on the last day of the tax year or $300,000 at any point during the year
• Married filing jointly: Total value exceeds $400,000 on the last day of the tax year or $600,000 at any point during the year

Form 8938 covers a broader range of assets than the FBAR — it includes not just bank and investment accounts but also foreign pension plans, interests in foreign entities, and foreign-issued life insurance and annuity contracts. The penalties for failure to file Form 8938 are severe:

• $10,000 penalty for failure to file
• Additional $10,000 for each 30-day period of continued non-filing after IRS notice, up to a maximum of $60,000
• 40% accuracy penalty on any underpayment of tax attributable to unreported foreign assets (IRC Section 6662(j))
• Extended statute of limitations: The normal 3-year statute of limitations does not begin to run until you file the Form 8938 — meaning the IRS can go back indefinitely if you never filed

For an American who moves to Canada and accumulates a house, an RRSP, a non-registered investment account, and a few bank accounts, the Form 8938 thresholds are easily exceeded. And remember: Form 8938 goes on your tax return (attached to Form 1040), while the FBAR goes to FinCEN separately. Missing one does not excuse missing the other. You may need to file both — reporting overlapping (but not identical) sets of accounts on two different forms to two different agencies with two different penalty regimes.

Trap 5: RESP Complications

Canada's Registered Education Savings Plan (RESP) is a staple of Canadian family financial planning. Contributions grow tax-deferred, and the federal government tops up your contributions with the Canada Education Savings Grant (CESG) — a 20% match on the first $2,500 contributed each year, up to $500/year and $7,200 lifetime per beneficiary. For Canadian families, it is one of the most attractive savings vehicles available.

For Americans, the RESP creates multiple problems:

• No treaty protection: Unlike the RRSP, the RESP has no protection under the US-Canada Tax Treaty. Article XVIII(7) of the treaty specifically covers RRSPs and RRIFs — but RESPs are not mentioned. This means the IRS does not defer the tax on investment growth inside the RESP.
• Growth may be currently taxable: Since the US does not recognize the RESP's tax-deferred status, the investment growth inside the RESP is likely taxable to the subscriber (the parent) as it accrues — similar to the TFSA treatment
• CESG may be taxable income: The Canada Education Savings Grant — free government money in Canada — may be treated as income for US tax purposes when received. The IRS could characterize it as a foreign government grant or as income from a foreign trust
• Foreign trust reporting: Depending on how the IRS characterizes the RESP, it may require Form 3520 and/or Form 3520-A reporting — the same forms (and penalties) as the TFSA
• PFIC exposure: If the RESP holds Canadian mutual funds (most do), each fund is a PFIC requiring Form 8621 reporting — compounding the compliance cost

The practical advice for Americans in Canada with children: the RESP is still worth having for the CESG match (it is literally free money from the Canadian government), but you must account for the US reporting obligations and potential current taxation. Work with a cross-border advisor to structure the RESP holdings to minimize PFIC exposure — for example, by holding only GICs (Guaranteed Investment Certificates) or individual Canadian stocks rather than mutual funds inside the RESP. And budget for the additional compliance cost.

The RRSP: The One Account That Actually Works for Dual Citizens

Good news exists in this landscape. The Registered Retirement Savings Plan (RRSP) is the one major Canadian account that is properly recognized by the US tax system, thanks to the US-Canada Tax Treaty.

Article XVIII(7) of the US-Canada Tax Treaty allows US citizens and residents to elect to defer US taxation on income accruing within an RRSP or RRIF until distributions are made. This mirrors the Canadian treatment — contributions reduce taxable income, growth is tax-deferred, and you pay tax only on withdrawal.

Historically, claiming this treaty benefit required filing Form 8891 (US Information Return for Beneficiaries of Certain Canadian Registered Retirement Plans) every year with your tax return. Missing a single year of Form 8891 could void the deferral election for all years. In 2014, the IRS issued Revenue Procedure 2014-55, which made the treaty deferral election automatic for all taxpayers. You no longer need to file Form 8891 or make an annual election — the deferral applies by default as long as you are eligible.

However, the RRSP is not without traps for US citizens:

• RRSP contributions may not be deductible on your US return: You can deduct RRSP contributions on your Canadian T1, but the US deduction is limited. Under the treaty, the deduction is generally limited to earned income from Canadian sources and cannot exceed the US contribution limits for equivalent accounts. In practice, most dual citizens get the Canadian deduction but not a US deduction for RRSP contributions
• PFIC holdings within the RRSP still require Form 8621: The treaty defers the tax, but does not eliminate the reporting requirement. Each Canadian mutual fund inside your RRSP is still a PFIC that needs its own Form 8621
• FBAR and Form 8938 reporting: Your RRSP must be reported on both the FBAR and (if thresholds are met) Form 8938, even though the income is treaty-deferred

RRSP vs 401(k): What Happens When You Move

If you are an American with an existing 401(k), traditional IRA, or Roth IRA who is considering a move to Canada, here is how each account is treated after you become a Canadian resident:

The critical pre-move strategy: Max out your Roth IRA contributions while you still have US earned income. Once you move to Canada and no longer earn US-source income, you lose the ability to contribute to a Roth IRA. The Roth is the most tax-efficient account for Americans because qualified withdrawals are tax-free — and that tax-free status persists even after you move to Canada (for US purposes). Front-load as much as possible into the Roth before the move.

Trap 6: The Dual Filing Obligation — Two Countries, Two Returns, Every Year

Here is the reality that Bill C-3 applicants do not think about: once you are a US citizen living in Canada, you file two complete income tax returns every year. A US Form 1040 reporting your worldwide income to the IRS, and a Canadian T1 General reporting your worldwide income to the CRA. Every year. For the rest of your life. Unless you renounce one citizenship.

The US return is not a formality. Even though Canada's tax rates are generally higher than US rates (meaning the Foreign Tax Credit usually offsets the US tax), you must still:

• File Form 1040 reporting all worldwide income
• File Form 1116 (Foreign Tax Credit) to claim credit for Canadian taxes paid
• Consider Form 2555 (Foreign Earned Income Exclusion) if you want to exclude up to $132,900 of earned income for 2026
• File FinCEN Form 114 (FBAR) reporting all Canadian financial accounts
• File Form 8938 if foreign assets exceed the thresholds
• File Form 8621 for each PFIC (Canadian mutual fund or ETF)
• File Form 3520/3520-A if you hold a TFSA (which you should not)
• File Form 8833 (Treaty-Based Return Position Disclosure) if you claim treaty benefits

Estimated annual compliance cost: $2,000-$5,000 for cross-border tax preparation by a qualified professional. This is not generic H&R Block territory — cross-border returns require a preparer who understands both the IRC and the ITA, the US-Canada Tax Treaty, PFIC rules, foreign trust reporting, and the interaction between the FTC and Canadian credits. Getting it wrong does not just mean overpaying taxes — it means penalty exposure on the information returns.

The key deadlines for US citizens in Canada:

• Canadian T1: Due April 30 each year
• US Form 1040: Due April 15, with automatic 2-month extension to June 15 for taxpayers abroad. Can be further extended to October 15 with Form 4868
• FBAR: Due April 15, automatic extension to October 15
• Form 3520-A: Due March 15 (this is earlier than your tax return)

Trap 7: The Exit Tax — What Happens if You Later Renounce US Citizenship

Some Americans who move to Canada under Bill C-3 will eventually decide that the dual filing burden is not worth it and consider renouncing US citizenship. Before you do, understand IRC Section 877A — the exit tax.

You are a "covered expatriate" if, on the date of expatriation, you meet any one of these three tests:

1. Net worth test: Your net worth is $2 million or more
2. Average tax liability test: Your average annual net income tax liability for the five tax years preceding expatriation exceeds approximately $211,000 (2026 inflation-adjusted threshold)
3. Certification test: You cannot certify on Form 8854 that you have been in compliance with all US tax obligations for the five years preceding expatriation

If you are a covered expatriate, IRC 877A imposes a mark-to-market deemed sale on all worldwide assets as of the day before your expatriation date. Every asset — stocks, real estate, business interests, crypto, collectibles — is treated as sold at fair market value. The net gain above the $910,000 exclusion amount (2026 inflation-adjusted) is taxed at capital gains rates. This is a tax on unrealized gains — you owe the money without having sold anything.

Retirement accounts get even worse treatment. Traditional and Roth IRAs are treated as fully distributed on the day before expatriation — the entire balance is taxed in a single year. 401(k) and employer pensions face a permanent 30% withholding on every future distribution, with no treaty relief available.

One piece of good news: the renunciation fee dropped from $2,350 to $450, effective April 13, 2026. But the administrative fee is the smallest part of the equation. The exit tax is where the real cost lives.

The 1% Remittance Tax: Another Trap for Non-Citizen Spouses

The One Big Beautiful Bill Act (OBBBA), signed into law on July 4, 2025, introduced a 1% federal excise tax on outbound remittances from the United States, effective January 1, 2026. This tax applies to international money transfers sent through banks, wire services, money order providers, and other licensed money transmitters.

For Bill C-3 families, this hits a specific scenario: the non-citizen spouse. If you are an American who claims Canadian citizenship under Bill C-3 and moves to Canada with a Canadian spouse who is not a US citizen, any transfers your spouse makes from US-based accounts to Canada are subject to the 1% excise tax. It also affects families who maintain US bank accounts after moving — transferring your own after-tax dollars from a US account to your Canadian account triggers the 1% levy.

At first glance, 1% seems trivial. But for a family transferring $100,000 from the sale of a US home to fund a Canadian down payment, that is a $1,000 tax on moving your own money. For retirees drawing $5,000/month from US accounts, it is $600/year in perpetuity. The remittance tax was designed to target undocumented workers, but the statute does not distinguish by citizenship or immigration status — all outbound transfers are hit.

Before You Move Checklist: 12 Steps to Take While You Are Still in the US

If you are claiming Canadian citizenship under Bill C-3 and planning a move, complete these steps before you leave the United States. The order matters — several of these become impossible or much harder once you are a Canadian resident.

1. Max out your Roth IRA. Contribute the maximum ($7,000 for 2026, or $8,000 if you are 50+) while you still have US earned income. Once you move and no longer earn US-source income, you cannot contribute. The Roth's tax-free growth and tax-free qualified withdrawals make it the most valuable account for future dual citizens.
2. Max out your 401(k). Contribute the maximum ($23,500 for 2026, or $31,000 if 50+) in your final year of US employment. Consider whether to roll into a traditional IRA after leaving your employer — an IRA gives you more investment control and easier cross-border management.
3. Do NOT buy Canadian ETFs or mutual funds yet. Wait until you have a cross-border advisor in place who can help you invest in US-listed, US-domiciled ETFs and individual stocks that avoid the PFIC trap entirely. Vanguard, Schwab, and iShares US-listed ETFs are not PFICs.
4. Consolidate and document all US financial accounts. Know exactly where every account is, what the balances are, and what is in each one. You will need this for FBAR and Form 8938 reporting from day one in Canada.
5. Hire a cross-border tax advisor BEFORE you move. Not after. Not "when tax season comes." Before you leave the US. The advisor will review your entire financial picture and identify issues while there is still time to restructure. Book a consultation with our cross-border team.
6. Understand the FEIE vs FTC decision. The Foreign Earned Income Exclusion (Form 2555, up to $132,900 for 2026) and the Foreign Tax Credit (Form 1116) are both available, but you generally cannot use both on the same income. For most Americans in Canada, the FTC is better because Canadian tax rates are higher — but your advisor should model both scenarios.
7. Review your investment portfolio for PFIC exposure. If you already hold any Canadian-domiciled funds, ETFs, or investment trusts, identify them now. Your cross-border advisor can help you determine the exit strategy — whether to sell before moving (crystallizing gains at favorable US rates) or hold and elect mark-to-market.
8. Set up a record-keeping system for dual filing. You will need to track income, deductions, and credits across two tax systems with different currencies, different tax years (both are calendar-year, but treatment of items differs), and different forms. Start organized or you will pay for it later — both in accounting fees and missed deductions.
9. Do NOT open a TFSA. When you arrive in Canada, your bank will push this hard. Politely decline. The US tax cost of a TFSA (foreign trust reporting, current taxation of growth, PFIC exposure) far exceeds the Canadian tax benefit for any US citizen.
10. Plan the timing of your move carefully. Moving mid-year creates a split year where you are a Canadian resident for only part of the year, which affects your eligibility for the Foreign Tax Credit and Foreign Earned Income Exclusion. A January 1 move is cleanest; your advisor can help you determine the optimal date.
11. Understand your Canadian entry obligations. You will need a Social Insurance Number (SIN), and you should apply for provincial health insurance as soon as you arrive. Know the waiting period for health coverage in your province (Ontario is now zero days; other provinces may differ).
12. Budget $2,000-$5,000/year for ongoing tax compliance. This is not optional. Cross-border tax preparation by a qualified professional is a required annual expense for the rest of your time as a dual citizen. Factor it into your cost-of-living calculations before deciding to move. See our cross-border filing packages.

Frequently Asked Questions

Does claiming Canadian citizenship under Bill C-3 trigger US tax consequences?

Claiming Canadian citizenship itself does not trigger any US tax event. You do not owe US tax simply for becoming a dual citizen. The tax consequences arise when you move to Canada and begin earning income, opening accounts, and investing in Canadian financial products. At that point, you become subject to both Canadian taxation on your worldwide income (as a Canadian resident) and continued US taxation on your worldwide income (as a US citizen), plus the full suite of US information reporting requirements — FBAR, FATCA, PFIC, and foreign trust forms.

Can I use a TFSA if I am an American citizen living in Canada?

You can, but you should not. There is no law preventing a US citizen from opening a TFSA. However, the IRS treats the TFSA as a foreign grantor trust, which means all investment growth is taxable annually on your US return, and you must file Forms 3520 and 3520-A each year. The penalties for missing these forms start at $10,000 per year per form. The small Canadian tax benefit of the TFSA is vastly outweighed by the US compliance cost and penalty risk. Every cross-border tax professional will tell you the same thing: skip the TFSA.

Are Canadian mutual funds really taxed at 50%+ by the IRS?

Under the PFIC excess distribution regime of IRC Section 1291, yes — the effective tax rate can exceed 50%. This happens because the gain is allocated across your entire holding period, taxed at the highest marginal rate for each prior year (currently 37%), and then an interest charge is added for the deemed underpayment. A $50,000 gain on a Canadian mutual fund held for 10 years can generate $25,000-$30,000 in US tax, compared to $7,500-$10,000 if the same gain occurred in a US-domiciled fund taxed at long-term capital gains rates. The solution is simple: invest in US-listed, US-domiciled ETFs (Vanguard, iShares, Schwab) to avoid PFIC classification entirely.

Is the RRSP safe for Americans?

The RRSP is the safest Canadian registered account for Americans, thanks to Article XVIII(7) of the US-Canada Tax Treaty, which provides for tax deferral on RRSP growth. Since Revenue Procedure 2014-55 (issued in 2014), the deferral election is automatic — you no longer need to file Form 8891. However, two caveats: (1) if your RRSP holds Canadian mutual funds, each fund is a PFIC requiring Form 8621, and (2) RRSP contributions may not be deductible on your US return even though they are deductible in Canada. Use US-listed ETFs inside the RRSP to avoid PFIC exposure.

What is the FBAR and do I need to file it?

The FBAR (FinCEN Form 114) is a report filed with the Financial Crimes Enforcement Network listing all foreign financial accounts where the aggregate maximum value exceeded $10,000 at any point during the year. If you live in Canada and have a single chequing account with more than approximately CAD $14,000, you almost certainly exceed the threshold — and once the threshold is triggered, every foreign account must be reported, regardless of individual balances. That includes your chequing, savings, RRSP, RESP, any TFSA (if you mistakenly opened one), investment accounts, and even accounts where you have signature authority but no ownership. Non-willful penalties are up to $10,000 per year; willful penalties are the greater of $100,000 or 50% of the account balance.

How much does it cost to file taxes as a US-Canada dual citizen?

Professional cross-border tax preparation typically costs $2,000-$5,000 per year, depending on the complexity of your situation. A straightforward W-2 employee with one RRSP and a couple of bank accounts will be on the lower end. A self-employed person with PFICs, a TFSA, an RESP, rental properties, and stock options will be on the higher end. This cost is for both the US return (1040, 1116, FBAR, 8938, and any 8621s) and coordination with the Canadian return. Attempting to do this yourself using consumer tax software like TurboTax is not recommended — cross-border returns require specialized knowledge that general-purpose software does not handle. View our cross-border tax preparation packages.

What happens if I have never filed US taxes and I have been living in Canada?

If you are a US citizen who has never filed US tax returns, the IRS Streamlined Foreign Offshore Procedures offer a structured path to compliance. You file three years of delinquent tax returns and six years of FBARs, certify that your non-compliance was non-willful, and pay any taxes and interest owed. For qualifying filers who lived outside the US during the compliance period, there is no penalty. Many dual citizens who catch up through this program discover they owe little or nothing after applying the Foreign Tax Credit. Do not start filing current-year returns without addressing prior years — enter through the Streamlined program with professional guidance.

Can I still contribute to a Roth IRA after moving to Canada?

Generally, no. Roth IRA contributions require US-source earned income (wages, salaries, self-employment income). Once you move to Canada and your income is from Canadian sources, you typically no longer have qualifying earned income for Roth IRA contributions — even though you are still a US citizen. There is a narrow exception if you earn US-source self-employment income or wages from a US employer while living in Canada, but most people lose the ability to contribute. This is why we emphasize maxing out the Roth before you move.

Does the 1% remittance tax apply to US citizens sending money to themselves in Canada?

Yes. The OBBBA remittance excise tax (effective January 1, 2026) applies to outbound international transfers regardless of the citizenship or immigration status of the sender or recipient. If you transfer $50,000 from your US bank account to your Canadian bank account, the 1% levy is $500. The tax was designed to target undocumented worker remittances but is written broadly enough to capture all outbound transfers. This particularly affects dual citizens who maintain US accounts and periodically move funds to Canada for living expenses, home purchases, or investments.

What is the cost of renouncing US citizenship if I decide to later?

The State Department administrative fee is $450 (reduced from $2,350 effective April 13, 2026). But the true cost depends on whether you are a "covered expatriate" under IRC 877A. If your net worth exceeds $2 million, or your average annual tax liability for the prior five years exceeds approximately $211,000, or you cannot certify five years of US tax compliance, you face the exit tax: a mark-to-market deemed sale of all worldwide assets, with gains above the $910,000 exclusion taxed at capital gains rates. IRAs are deemed fully distributed and taxed in one year. 401(k) distributions face permanent 30% withholding. And under IRC Section 2801, gifts and bequests to US persons are taxed at 40%. For a covered expatriate with $3 million in assets, the total exit tax can exceed $100,000+.

Do I need to report my Canadian bank accounts even if I owe no US tax?

Yes, absolutely. The FBAR and FATCA reporting requirements are information reporting obligations — they exist independently of whether you owe any US tax. You can owe $0 to the IRS (because the Foreign Tax Credit offsets everything) and still face $10,000+ in penalties for failing to file the FBAR or Form 8938. The penalty is for not reporting, not for not paying. This is the most common misconception among dual citizens: "I don't owe anything, so I don't need to file." Wrong. You must file the returns and the information reports every year, even when the tax due is zero.

Should I avoid the RESP for my children if I am American?

No — the RESP is still worth having because the Canada Education Savings Grant (CESG) provides a 20% match on the first $2,500 contributed per year. That is $500/year of free government money, up to $7,200 lifetime per child. The trade-off is the US reporting burden: the RESP is not treaty-protected, growth may be currently taxable on your US return, and CESG may be treated as income. The key is to structure the RESP investments to avoid PFICs — hold GICs, individual stocks, or US-listed ETFs inside the RESP rather than Canadian mutual funds. Budget for the additional US reporting cost, and the RESP remains a net positive because of the CESG match.
