Note: This article covers the tax treaty between the US and Canada as it applies to Canadian residents investing in US assets. It is educational and does not constitute tax or financial advice. Tax rules change - verify current rates with a qualified tax professional.
A Canadian investor bought $20,000 of a US dividend ETF in her TFSA. She expected the 3% annual dividend - $600 per year. What arrived was $510. The missing $90 was US withholding tax deducted before the dividend ever reached her account. Unlike in her RRSP, she could not recover it.
That $90 is not a mistake. It is the predictable, documented result of how the US-Canada tax treaty interacts with different account types. Understanding that interaction - and choosing the right account for each asset type - is worth more than most investment decisions a Canadian investor makes.
This guide covers the treaty rules that matter for Canadian investors: what each income type is withheld at, which accounts eliminate or preserve the withholding, and what to file to make sure you are paying the minimum the law requires.
The Treaty in Plain Terms
Canada and the United States have maintained a comprehensive tax treaty since 1980, updated through five protocols (the most recent in 2007). Its purpose is to prevent the same income from being taxed twice - once in the country where it originates and once in the country where the investor lives.
For Canadian investors holding US assets, the treaty does three things:
First, it reduces US withholding tax on dividends from the domestic 30% default to 15% for most investors (Article X). Second, it caps US withholding on interest income at 15%, with full exemptions for certain categories (Article XI). Third, it eliminates US withholding entirely on capital gains from selling US securities - with narrow but important exceptions involving US real property (Article XIII).
The treaty also contains a provision that most investment articles miss: a full exemption from US dividend withholding for income earned inside an RRSP. That exemption is the single most actionable planning tool available to Canadian investors in US assets.
Withholding Rates: What Each Income Type Costs
The US applies withholding at source before income reaches a foreign investor. Without a treaty, the default rate is 30% on dividends and interest. The US-Canada treaty reduces these rates - but not to zero, and not for every account type.
Dividends from US corporations
Under Article X of the treaty, US withholding on dividends paid to individual Canadian investors is reduced from 30% to 15%. This applies to dividends from US corporations - Apple, Microsoft, Johnson & Johnson, and similar companies.
The 15% rate requires one condition: you must submit Form W-8BEN to your broker certifying your Canadian residency. Without it, the full 30% default applies. The W-8BEN is valid for three years and must be renewed when it expires.
For Canadians investing in US stocks through a Canadian broker (TD Direct, RBC Direct, Questrade), the broker typically files W-8BEN on your behalf as part of account setup. Verify this is in place, especially if your account is more than three years old.
Interest income from US sources
Article XI caps US withholding on interest at 15% for arm’s length debt obligations. Several categories are fully exempt from US withholding: interest paid by the US government or a US state, interest on trade credits between arm’s length parties, and interest that would have been exempt under the 1942 convention.
In practice, most interest income Canadian investors receive from US bonds, GICs or savings accounts is subject to the 15% treaty rate. The full exemptions apply in narrow circumstances that rarely affect retail investors.
Capital gains from selling US securities
Article XIII(4) provides that gains from selling personal property - which includes stocks, ETFs, and bonds - are taxable only in the country where the investor lives. For a Canadian resident selling US stocks, the gain is taxable in Canada and not subject to any US withholding.
This is a meaningful advantage. A Canadian investor who bought $50,000 of SPY and sells at $80,000 pays no US tax on the $30,000 gain. Canadian capital gains inclusion at 50% means $15,000 is added to taxable income and taxed at the investor’s marginal rate.
The exception: gains from selling shares of companies whose value is derived principally from US real property (Article XIII(3)). This covers US REITs under FIRPTA rules - discussed separately below.
REIT distributions
US REIT ordinary income distributions are treated as ordinary income, not qualified dividends. For Canadian investors, the 15% treaty rate applies to US REIT dividend distributions as for other US dividends. However, if you sell REIT shares, FIRPTA applies: 15% of gross sale proceeds is withheld at the point of sale. This withholding is applied against actual US tax owed and refunded via a US non-resident return (Form 1040-NR) if the withholding exceeds the liability - but the complexity and paperwork are real.
The Account-by-Account Breakdown
This is where the treaty becomes genuinely complex - and where most guides stop short. The same US stock can produce three different after-withholding outcomes depending on which account holds it.
RRSP: The Best Account for US Dividends
Article XXI(7) of the treaty - added by the Fifth Protocol in 2007 - provides that pension funds and retirement arrangements recognized by the other country are generally exempt from withholding tax on dividends and interest. The Canada Revenue Agency and IRS have confirmed that RRSPs, RRIFs, and RPPs qualify as recognized pension arrangements under this provision.
The result: US dividends earned inside an RRSP are exempt from US withholding entirely. Where a non-registered account pays 15% withholding on every US dividend, the RRSP receives the gross amount.
Concrete example: a Canadian investor holds $100,000 of VTI (Vanguard Total Stock Market ETF, US-domiciled) with a 1.4% distribution yield.
- In a non-registered account: $1,400 in annual distributions, $210 withheld (15%), $1,190 received
- In an RRSP: $1,400 in annual distributions, $0 withheld, $1,400 received
Over 20 years at constant yield and 7% annual growth, the RRSP advantage on this $100,000 position compounds to a material difference in terminal value - entirely from the elimination of withholding drag.
The practical implication for asset location: US dividend-paying stocks and US equity ETFs belong inside the RRSP. Canadian dividend stocks and fixed income, which carry no US withholding risk, are better placed in other accounts.
TFSA: The Withholding Trap
The TFSA is not recognized as a pension arrangement or exempt organization under the US-Canada treaty. The 15% US dividend withholding applies in full to US-source income earned in a TFSA - and, critically, cannot be recovered.
In a non-registered account, the 15% US withholding is creditable against Canadian tax owed. A Canadian investor in a 33% marginal bracket who pays 15% US withholding on a $1,000 US dividend pays 15% to the US and 18% to Canada (total 33%). No double taxation - the foreign tax credit eliminates the overlap.
In a TFSA, there is no Canadian tax on the income, so there is no Canadian tax against which to credit the US withholding. The 15% is simply lost. Permanently.
This makes holding US dividend-paying assets in a TFSA a structural tax inefficiency. The TFSA is excellent for Canadian stocks, Canadian ETFs, and growth assets that produce little or no income. It is the wrong account for US dividend payers.
The same applies to RESP, FHSA, and RDSP accounts - none qualify for the RRSP treaty exemption, and withholding cannot be recovered in these accounts.
Non-Registered Account: Withholding Plus Foreign Tax Credit
In a taxable (non-registered) account, the 15% US withholding is applied at source and reported on your annual tax slip (T3 or T5, depending on the source). When you file your Canadian return, you claim a foreign tax credit under Article XXIV of the treaty for the US taxes paid.
The foreign tax credit eliminates double taxation on the dividends, but does not produce a refund if the US withholding exceeds your Canadian marginal rate on the income. For most Canadians - particularly those in higher provincial brackets with combined rates of 43-54% - the 15% US withholding is creditable in full, with the remaining Canadian rate applied on top.
Capital gains from US stocks in a non-registered account are taxed only in Canada (Article XIII), at 50% inclusion with your marginal rate. No US withholding applies. No foreign tax credit is needed.
Canadian Capital Gains Tax in 2026: What Actually Applies
This section addresses a question that confused many Canadian investors for nearly two years.
The 2024 federal budget proposed increasing the capital gains inclusion rate from 50% to 66.67% for individuals on annual gains above $250,000, and for all corporate and trust gains. The effective date was pushed from June 2024 to January 2026 - then cancelled entirely in March 2025 by Prime Minister Carney’s government.
The capital gains inclusion rate in Canada in 2026 is 50%. The proposed increase was never enacted into law.
What this means in practice: when a Canadian investor sells US stocks at a gain in a non-registered account, 50% of the gain is included in taxable income and taxed at the investor’s combined federal-provincial marginal rate. The other 50% is not taxed.
Federal marginal rates for 2026 (verified from KPMG’s 2026 federal and provincial tax rates table and CRA):
| Federal Taxable Income | Federal Rate |
|---|---|
| Up to $58,523 | 14% |
| $58,524 - $117,045 | 20.5% |
| $117,046 - $181,440 | 26% |
| $181,441 - $258,482 | 29% |
| Over $258,482 | 33% |
Provincial rates are added on top. Combined federal-provincial marginal rates in 2026 range from approximately 44% (Alberta) to 54% (Quebec and Nova Scotia) at the highest income levels.
For a Canadian investor with combined marginal rate of 50% realizing a $100,000 capital gain on US stocks: $50,000 is included in income ($100,000 x 50%), taxed at 50% = $25,000 in tax. Effective rate on the total gain: 25%. No US withholding applies. No foreign tax credit needed.
Form W-8BEN: What It Does and What It Does Not Do
Filing Form W-8BEN with your broker certifies your status as a non-US person and applies the treaty rate to your income. For Canadian individual investors, it reduces US dividend withholding from 30% to 15%.
What W-8BEN does not do:
- It does not reduce RRSP withholding to zero. The RRSP exemption is automatic and separate from W-8BEN - it is based on the account type, not the investor’s certification.
- It does not protect TFSA, RESP, or FHSA income from withholding. Those accounts are not exempt under the treaty regardless of the form filed.
- It does not affect capital gains treatment. Capital gains from US securities are exempt from US withholding by treaty (Article XIII) for any Canadian resident, W-8BEN or not.
The W-8BEN must be renewed every three years. If it expires, your broker reverts to the 30% default rate. Most major Canadian brokers (Questrade, RBC Direct, TD Direct Investing, IBKR Canada) prompt renewal automatically - but it is worth verifying the status of the form in your account if you have been holding US securities for more than three years.
The RRSP Contribution Room Constraint
The RRSP withholding exemption creates a clear planning signal: maximize US equity holdings inside RRSP contribution room before putting them in a TFSA or non-registered account.
The constraint is that RRSP room is finite. In 2026, the contribution limit is 18% of previous year’s earned income, to a maximum of $32,490. Investors with significant US equity positions may not have enough RRSP room to hold all of them inside the exemption.
The prioritization framework:
- US dividend-paying stocks and US equity ETFs - maximize inside RRSP
- High-growth US stocks with minimal current income - TFSA is acceptable (capital gains are treaty-exempt from US withholding; the TFSA inefficiency only bites on dividend income)
- Canadian dividend stocks and Canadian equity ETFs - TFSA is efficient (no US withholding, no Canadian tax in TFSA)
- Fixed income and interest-bearing assets - RRSP or TFSA (shielded from Canadian tax; interest withholding not recoverable in TFSA)
- US REITs - RRSP strongly preferred, given FIRPTA complexity on exit and 15% withholding on distributions in taxable/TFSA accounts
Numerical Example: Three Accounts, Same US Dividend ETF
An investor holds $50,000 of VYM (Vanguard High Dividend Yield ETF, US-domiciled), yielding approximately 2.8% annually ($1,400 in distributions). Combined federal-provincial marginal tax rate: 46%.
| Account | US Withholding | Canadian Tax | Net Received | Annual After-Tax Income |
|---|---|---|---|---|
| RRSP | $0 (treaty exempt) | $0 (deferred until withdrawal) | $1,400 | $1,400 (deferred) |
| TFSA | $210 (15%, non-recoverable) | $0 | $1,190 | $1,190 |
| Non-registered | $210 (15%, creditable) | $434 (46% x $1,400 = $644, less $210 credit) | $756 | $756 |
RRSP income is taxed at withdrawal at the investor’s then-current marginal rate. Non-registered calculation: gross $1,400, Canadian tax at 46% = $644, less foreign tax credit of $210 = net Canadian tax of $434. Total tax = $644 ($210 US + $434 Canada). After-tax income = $756. Amounts depend on province and personal situation - consult a tax professional.
The RRSP outcome is the most favorable: the full $1,400 accumulates inside the account, taxes deferred until withdrawal. The TFSA loses $210 permanently with no recovery mechanism. The non-registered account loses the most in the current year but the foreign tax credit prevents full double taxation.
Common Mistakes Canadian Investors Make
Holding US dividend ETFs in a TFSA. The most widespread and costly error. 15% withholding on US dividends in a TFSA is permanent tax leakage. A $100,000 US dividend position at 2.5% yield loses $375 per year to non-recoverable US withholding. Over 20 years at 7% growth, this compounds into a significant drag.
Not renewing W-8BEN. When the form expires (every three years), brokers default to 30% withholding. Many investors do not notice the higher rate because it is deducted before the dividend arrives. The difference between 15% and 30% on $5,000 of annual US dividends is $750 per year in unnecessary tax.
Treating RRSP and RRIF differently. The treaty exemption covers both RRSP and RRIF accounts. Many investors assume the exemption ends when they convert to a RRIF at age 71. It does not.
Assuming Canadian-listed US equity ETFs avoid US withholding. Canadian-listed ETFs that hold US stocks (XUS, VFV, ZSP) still receive US dividends, which are subject to US withholding at the ETF level before the ETF passes them through. The RRSP treaty exemption applies directly when you hold a US-domiciled ETF in your RRSP - but the withholding at the ETF level for Canadian-domiciled ETFs is a layer that the treaty exemption does not fully eliminate, even in an RRSP. For maximum efficiency in an RRSP, holding the US-domiciled ETF directly (SPY, VTI, VYM) captures the full treaty exemption. Canadian-domiciled ETFs holding US stocks in an RRSP partially benefit from the exemption through the Canada-US treaty at the fund level, but efficiency depends on how the fund is structured.
Ignoring the foreign tax credit in non-registered accounts. Many investors assume they are double-taxed on US dividends. They are not, thanks to Article XXIV. The 15% US withholding is creditable against Canadian tax owed on the same income. The credit must be claimed on Schedule T2209 of your Canadian return.
Frequently Asked Questions
Does W-8BEN reduce US withholding to 15% for Canadians on all income types? For dividends from US corporations, yes - W-8BEN applies the Article X treaty rate of 15%. For US interest income, the treaty cap is also 15% under Article XI. For capital gains from US securities, no withholding applies under Article XIII regardless of W-8BEN. The RRSP exemption is separate and does not require W-8BEN.
Is capital gains tax owed in the US when a Canadian sells US stocks? No. Article XIII(4) of the US-Canada treaty gives Canada exclusive taxing rights on capital gains from the sale of US securities by Canadian residents. No US withholding applies at the point of sale. The gain is reported on your Canadian return and taxed at 50% inclusion.
What is the withholding rate on US REIT distributions for Canadians? The 15% treaty rate applies to US REIT ordinary dividend distributions for individual Canadian investors. When selling REIT shares, FIRPTA requires 15% withholding on gross sale proceeds at the point of sale. This withholding can be recovered by filing a US non-resident return if it exceeds actual US tax owed, but the process requires professional assistance.
Is the RRSP treaty exemption automatic or does it require filing? The exemption under Article XXI(7) is based on the account type. Canadian brokers applying the RRSP exemption do so automatically when US securities are held inside a registered RRSP account. No separate filing by the investor is required, though your broker may maintain documentation for compliance purposes.
Can the TFSA withholding be recovered? No. US dividends withheld in a TFSA cannot be credited against Canadian tax because there is no Canadian tax on TFSA income to offset. The withholding is a permanent cost. This is why US dividend-paying assets are inefficient in a TFSA.
Did Canada’s capital gains inclusion rate change in 2026? No. The proposed increase from 50% to 66.67% was cancelled by Prime Minister Carney’s government in March 2025 and was never enacted into law. The inclusion rate for individuals in 2026 remains 50%.
What if I hold US stocks through a Canadian-listed ETF - does withholding still apply? Yes. Canadian-domiciled ETFs that hold US stocks (such as XUS, VFV, ZSP) receive US dividends subject to US withholding at the fund level. The treaty partially reduces this withholding at the fund level when the ETF is held in an RRSP, but the mechanics differ from holding the US ETF directly. For full RRSP withholding efficiency, holding US-domiciled ETFs (SPY, VTI, VYM) directly inside your RRSP captures the complete Article XXI(7) exemption.
The One Decision That Matters Most
Canadian investors with access to both an RRSP and a TFSA face a straightforward asset location decision for US equity holdings.
US dividend-paying stocks and US equity ETFs belong in the RRSP. The treaty exemption eliminates 15% withholding drag that compounds against returns over decades. That same 15% withholding in a TFSA is gone permanently, with no recovery mechanism.
Canadian equities, growth stocks with minimal income, and tax-efficient assets can go in the TFSA without the withholding penalty.
Non-registered accounts are the last resort for US dividend payers - the foreign tax credit prevents double taxation, but current-year tax on distributions is significant.
File W-8BEN with your broker. Renew it before it expires. Hold US dividend assets inside RRSP room. These three steps, applied consistently, add up to a material advantage over an investing lifetime.
For a side-by-side comparison of rates across major US treaties, see our tax map or compare the US-Australia and Canada treaties directly. While both Commonwealth countries enjoy US capital gains tax exemption (residence-only taxation) and similar 15% dividend rates, Canada’s RRSP exemption (0% withholding) and 15% interest rate differ from Australia’s super treatment (15% floor) and 10% interest rate.
