US Expat Taxes in Canada: The Complete Guide for 2026

---

Canada is the most common destination for Americans moving abroad. Shared language, geographic proximity, a robust economy, and universal healthcare make it a natural first step. It is also the country where the two tax systems interact most frequently, and where the planning decisions most commonly get made by default rather than by design.

The short answer: US citizens in Canada still file a US tax return every year, report worldwide income, and use the Foreign Tax Credit to offset Canadian taxes paid. Canada’s combined rates are high enough that most Americans in Canada owe zero US federal tax after credits. But two Canadian accounts, the RRSP and the TFSA, are treated completely differently by the IRS, and getting that wrong is the most common and costly mistake Americans make in Canada.

This guide covers the Canadian tax system for 2026, how the FEIE and Foreign Tax Credit interact with Canadian taxes, the RRSP and TFSA treatment that catches most Americans off guard, FBAR, the US-Canada tax treaty, and the pre-departure steps that determine how much of the move’s financial benefit you actually capture.

Do US citizens living in Canada still have to file US taxes?

Yes. The US taxes its citizens on worldwide income regardless of where they live. Moving to Canada does not end your US filing obligation. If your worldwide income exceeds the filing threshold, you are required to file a US federal tax return each year, whether you have been in Canada for one year or twenty-one.

What changes when you move to Canada is not whether you file, but how you file and which tools are available to reduce what you owe. Canada’s combined federal and provincial tax rates consistently exceed equivalent US rates, which means the Foreign Tax Credit typically eliminates US federal tax liability for most employed Americans in Canada. But the filing obligation remains.

How Canada taxes residents in 2026

Canada taxes its residents on worldwide income. You become a Canadian tax resident when you establish significant residential ties to Canada, primarily a home available for your use, a spouse or dependents in Canada, or social and economic ties that make Canada your primary place of residence.

Canadian income tax has two layers: federal and provincial. Federal income tax rates for 2026 are:

Up to $57,375: 14% (reduced from 15% under Bill C-4, effective for the full 2026 tax year) $57,376 to $114,750: 20.5% $114,751 to $158,519: 26% $158,520 to $220,000: 29% Above $220,000: 33%

Provincial rates add significantly to the federal rate. Combined federal and provincial effective rates typically range from 40% to 53.5% for middle and higher earners. Ontario’s combined top rate is approximately 53.53%. Quebec reaches a similar level. Alberta’s flat 10% provincial rate produces a lower combined rate of approximately 48% at the top.

The Canadian tax return (T1) is due April 30. Self-employed Canadians have until June 15 to file, but any taxes owed are still due April 30.

The FEIE or the Foreign Tax Credit: which works better in Canada?

For most Americans in Canada, the Foreign Tax Credit is the better choice, and the margin is usually not close.

Canada’s combined federal and provincial effective rates consistently exceed equivalent US federal rates. A US citizen in Ontario earning CAD $120,000 (approximately USD $87,000) pays approximately CAD $28,000 to $32,000 in combined Canadian tax, an effective rate of roughly 30 to 35%. The equivalent US federal tax on the same income is approximately $16,000 to $20,000. The FTC offsets the US liability dollar-for-dollar using Canadian taxes paid, typically producing zero US federal tax owed with meaningful excess credits carrying forward for up to ten years.

The Foreign Earned Income Exclusion excludes up to $132,900 of foreign-earned income from US taxable income in 2026. In Canada, it can also produce zero US federal tax for earnings below that threshold, but it has two significant drawbacks.

The FEIE does not apply to passive income. Canadian rental income, dividends, and capital gains remain on your US return regardless of the FEIE election. The FTC can offset Canadian taxes on all income categories including passive.

The FEIE limits IRA contribution eligibility. If all your earned income is excluded, you have no remaining earned income to support a traditional or Roth IRA contribution. For Americans who want to continue building US retirement savings while living in Canada, the FTC preserves that option. One important rule applies in both directions: once you claim the FEIE and revoke it in favor of the FTC, you generally cannot reclaim the FEIE for five years without IRS approval.

The RRSP: is it treaty-protected for US citizens?

The Registered Retirement Savings Plan is Canada’s primary tax-deferred retirement vehicle, equivalent in concept to a US traditional IRA. For most Canadians, RRSP contributions are deductible from taxable income and growth inside the plan is tax-deferred until withdrawal.

For US citizens, the RRSP has an important and often underutilized benefit: treaty protection under Article XVIII(7) of the US-Canada tax treaty. Under this provision, US citizens can elect to defer US taxation of income accruing inside an RRSP until funds are withdrawn. Without this election, the IRS would tax RRSP growth annually as a foreign grantor trust, which is a significantly worse outcome.

The election is made on your US return and must be made in the first year you hold the RRSP. Once made, it continues automatically. If you have an RRSP and have not made this election, you may be paying unnecessary US tax on deferred income that the treaty is designed to protect.

RRSP withdrawals are taxable in both Canada and the US. Canada withholds tax at source (25% for non-residents, 15% for periodic payments under the treaty). The Canadian withholding tax paid is creditable on the US return as a Foreign Tax Credit.

The 2026 RRSP contribution limit is 18% of prior year earned income, to a maximum of CAD $31,560. Contributions must be made by March 1, 2027 to count for the 2026 tax year.

The TFSA: why it is a tax trap for US citizens

The Tax-Free Savings Account is Canada’s tax-free investment vehicle. For Canadian residents generally, contributions grow tax-free and withdrawals are tax-free. The 2026 annual contribution limit is CAD $7,000.

For US citizens in Canada, the TFSA is a significant problem.

Unlike the RRSP, the TFSA has no treaty protection under the US-Canada tax treaty. All income generated inside a TFSA is fully taxable in the US as it accrues. Dividends, interest, and capital gains inside the account must be reported on your US return each year, regardless of the Canadian tax-free status.

The Form 3520 risk adds a further complication. The IRS may classify a TFSA as a foreign grantor trust, which would require filing Form 3520 (Annual Return to Report Transactions with Foreign Trusts) and Form 3520-A annually. The penalty for failure to file Form 3520 is 35% of the value of the property transferred to or from the trust, with a minimum penalty of $10,000. The IRS has not issued definitive guidance classifying TFSAs as foreign trusts, but the risk is real and well-documented in the expat tax community.

The practical guidance for most US citizens in Canada is straightforward: avoid the TFSA. The tax-free benefit it provides to Canadian residents does not extend to US citizens, and the potential Form 3520 exposure is a compliance risk not worth taking for a modest annual contribution limit.

If you currently hold a TFSA, reporting the income annually on your US return and confirming whether Form 3520 obligations apply to your specific account structure is worth discussing with a specialist.

FBAR and foreign account reporting in Canada

As a US citizen with Canadian bank accounts, FBAR obligations apply from your first year in Canada.

You are required to file an FBAR if the aggregate value of all your foreign financial accounts exceeds $10,000 at any point during the calendar year. The threshold is aggregate across all accounts, not per account. Canadian chequing accounts, savings accounts, RRSP accounts, TFSA accounts, and investment accounts all count toward the threshold. The FBAR is filed on FinCEN Form 114, separately from your tax return, with a deadline of April 15 and an automatic extension to October 15.

Form T1135 is the Canadian equivalent disclosure form. Canadian tax residents must file Form T1135 if the total value of specified foreign property exceeds CAD $100,000 at any point during the year. This is a Canadian filing obligation that applies to US citizens who are Canadian residents and have US investments, US bank accounts, or other US-based assets above that threshold.

Form 8938 is also required with your US return if your foreign financial assets exceed $200,000 at year-end or $300,000 at any point during the year for single filers abroad. Filing FBAR does not satisfy the Form 8938 obligation.

Canadian pensions, CPP and OAS

Canada Pension Plan contributions and Employment Insurance premiums are withheld from employment income by Canadian employers. US citizens working for Canadian employers pay into CPP in the same way Canadian citizens do.

CPP benefits received in retirement are taxable in both Canada and the US, with the treaty providing that only 85% of the benefit is included in US gross income, mirroring the treatment of US Social Security benefits. Canadian withholding tax on CPP payments is creditable on the US return.

Old Age Security payments received by US citizens resident in Canada are similarly taxed, with treaty provisions reducing the inclusion and the Canadian withholding tax creditable on the US return.

Workplace pension plans (defined benefit or defined contribution) sponsored by Canadian employers receive treaty protection similar to RRSP treatment in most cases. Growth inside an employer pension is generally not subject to US tax as it accrues. Withdrawals are taxable in both countries with treaty-based credits available.

The US-Canada tax treaty

The US and Canada have had a comprehensive tax treaty in force since 1980, most recently updated under the Fifth Protocol in 2007. The treaty addresses double taxation, establishes residency tie-breaker rules for dual-status situations, provides for reduced withholding rates on cross-border payments, and includes the RRSP deferral election discussed above.

The data-sharing provision under the treaty is worth noting: Canada and the US share tax information systematically. Income earned in Canada that is not reported to the IRS is much more likely to be detected than in jurisdictions without equivalent information-sharing agreements.

Treaty-based positions must be disclosed on Form 8833 when claimed on the US return.

The Totalization Agreement

The US-Canada Totalization Agreement prevents Americans in Canada from paying social security taxes to both countries simultaneously. The agreement has been in force since 1984.

For Americans working for a US employer on a Canadian assignment typically lasting less than five years, the agreement generally allows continuation of US Social Security contributions and exemption from CPP. A certificate of coverage from the US Social Security Administration confirms the exemption for CRA purposes.

For Americans working for a Canadian employer, contributions go to CPP rather than US Social Security. This means US Social Security credits are not accumulated on that income during the Canadian employment period.

For self-employed Americans in Canada, the Totalization Agreement is particularly valuable. US self-employment tax is 15.3% on top of income tax. Obtaining a certificate of coverage from the Canadian authorities confirming CPP contributions exempts you from the US self-employment tax on the same income. This is one of the most significant practical benefits of the agreement for self-employed expats.

US LLC taxation in Canada

Canada does not recognize a US single-member LLC as a pass-through entity. The CRA treats a US LLC operating in Canada as a corporation subject to Canadian corporate tax rates, which range from 25% to 31% depending on the province where the permanent establishment is located.

Americans running a Canadian business through a US LLC may also face a 25% branch tax on after-tax earnings above CAD $500,000. Certain treaty provisions may provide partial relief, but the analysis is situation-specific and the mismatch between US and Canadian treatment of LLC structures is one of the most common sources of unexpected tax costs for Americans doing business in Canada.

What to do before moving to Canada

Pre-departure planning is one of the most neglected areas in the Canada move, and some of the most consequential decisions happen in the weeks before departure rather than after arrival.

Consolidate US investment accounts. Reduce the number of US bank accounts, brokerage accounts, IRAs, and 401(k)s before moving. Canadian residents must report specified foreign property above CAD $100,000 on Form T1135. Fewer accounts with larger balances is generally easier to manage than many small accounts.

Consider the principal residence situation. If you own a US home, the timing of any sale relative to the move affects whether you can claim the US principal residence exclusion ($250,000 for single filers, $500,000 for married filing jointly) and what Canadian tax applies on future appreciation.

Review state tax ties. If you lived in a high-tax US state before moving to Canada, confirm whether your state considers you a continuing resident. California and New York are particularly aggressive about claiming ongoing state tax residency after a move abroad. Proper severance of state ties before departure is worth addressing.

Avoid contributing to a TFSA immediately upon arrival. The TFSA is one of the first accounts Canadian employers or banks suggest to new arrivals. For US citizens, it creates US tax complications without any corresponding US benefit.

Frequently asked questions

Is the FEIE or Foreign Tax Credit better for Americans in Canada?

For most Americans in Canada, the Foreign Tax Credit produces a better outcome. Canada’s combined federal and provincial tax rates consistently exceed equivalent US rates, generating FTC credits that fully offset US liability with excess credits carrying forward for up to ten years. The FEIE may be appropriate for lower earners or specific income compositions, but the FTC is the right default starting point for most employed Americans in Canada.

Is the TFSA tax-free for US citizens?

No. The TFSA is tax-free under Canadian rules but fully taxable for US citizens. All income inside a TFSA must be reported to the IRS annually. Unlike the RRSP, the TFSA has no treaty protection. There is also a potential Form 3520 filing obligation if the IRS classifies the TFSA as a foreign grantor trust, which carries significant penalties if missed.

Does the US-Canada treaty protect my RRSP from US taxes?

Yes, if you make the election under Article XVIII(7) of the treaty on your US return. This allows US citizens to defer US taxation of RRSP income until withdrawal, matching Canadian treatment. The election must be made the first year you hold the RRSP. Without it, RRSP growth is taxable in the US annually.

Do I have to file FBAR for my Canadian bank accounts?

Yes, if the aggregate value of all your foreign financial accounts exceeds $10,000 at any point during the year. This includes Canadian chequing accounts, savings accounts, RRSP accounts, and investment accounts. Canada and the US share financial account information under the treaty, making non-compliance more easily detected than in many other jurisdictions.

Can I run a US LLC in Canada?

Not without complications. Canada treats a US LLC as a corporation rather than a pass-through entity, subjecting Canadian income to corporate tax rates of 25% to 31% plus a potential branch tax. This is one of the most common sources of unexpected tax costs for Americans doing business in Canada.

How does the Totalization Agreement affect self-employment tax?

Self-employed Americans in Canada who contribute to CPP and obtain a certificate of coverage from Canadian authorities are exempt from the 15.3% US self-employment tax on the same income. This is one of the most significant practical benefits of the agreement for self-employed expats.
