Cross-Border Dividend Tax: Canada-US Treaty Rates and Credits

Dividends that cross the Canada-US border are taxed in both countries, with the treaty limiting the source country’s withholding and the residence country giving a credit for the tax withheld. The treaty rate on dividends is 15% for portfolio investors and 5% for corporate shareholders who own at least 10% of the voting stock. Without the treaty, the statutory withholding rate is 30% in the US (under IRC 1441) and 25% in Canada (under ITA 212(2)). The treaty rate is not automatic: the shareholder must provide the right form (W-8BEN for US dividends paid to a Canadian, NR301 for Canadian dividends paid to a US person) to claim the reduced rate.

How are US dividends taxed for Canadian residents?

A Canadian resident who owns shares in a US company (directly or through a US brokerage account) receives dividends subject to US withholding tax. With a properly filed Form W-8BEN, the withholding rate is 15% (the treaty rate). Without the form, the rate is 30%.

On the Canadian return:

• The dividend is reported as foreign income on line 12100 of the T1 (other income) or Schedule 4 (investment income). It is not eligible for the Canadian dividend gross-up and tax credit, because those apply only to dividends from taxable Canadian corporations.
• The 15% US withholding tax is claimed as a foreign tax credit on Form T2209 (Federal Foreign Tax Credits). The credit offsets Canadian tax on the same income.
• The dividend amount is converted from USD to CAD using the Bank of Canada exchange rate on the date of receipt (or the annual average).

The effective tax rate on US dividends for a Canadian resident depends on their marginal rate. At a 45% combined rate, the 15% US withholding plus the remaining Canadian tax (45% minus the 15% credit = 30%) produces a total tax of 45%, the same as if the dividend were Canadian-source foreign income.

RRSP and TFSA. US dividends received inside an RRSP are exempt from US withholding under Article XXI(2) of the treaty (zero rate for pensions and retirement arrangements). US dividends inside a TFSA are not exempt: the US does not recognize the TFSA as a retirement arrangement, so the 15% withholding applies. This is one reason holding US stocks inside a TFSA is tax-inefficient.

How are Canadian dividends taxed for US residents?

A US resident who owns shares in a Canadian company receives dividends subject to Canadian Part XIII withholding tax. With a properly filed Form NR301 (Declaration of Benefits Under a Tax Treaty for a Non-Resident Taxpayer), the withholding rate is 15%. Without the form, the rate is 25%.

On the US return:

• The dividend is reported on Schedule B (Interest and Ordinary Dividends). Canadian dividends are “ordinary dividends” for US purposes, but they may qualify as “qualified dividends” (taxed at the preferential 0%/15%/20% rate) if the Canadian company’s stock is traded on a US exchange or the dividend is otherwise eligible under IRC 1(h)(11).
• Most Canadian dividends from publicly traded Canadian corporations qualify as qualified dividends for US purposes, because the Canada-US treaty is a “qualified” treaty under the IRC definition.
• The 15% Canadian withholding tax is claimed as an FTC on Form 1116 (Foreign Tax Credit). The credit offsets US tax on the dividend income.
• The dividend is converted from CAD to USD at the IRS yearly average rate or the daily rate on the date of receipt.

If the US shareholder’s effective tax rate on qualified dividends (15% or 20% plus the 3.8% NIIT) exceeds the 15% Canadian withholding, there is a US tax residual after the credit. If the Canadian withholding equals or exceeds the US tax rate, the FTC eliminates the US tax, and excess credits carry forward under the Form 1116 limitation.

What about the Canadian dividend gross-up and credit?

The Canadian dividend gross-up and dividend tax credit mechanism under ITA 82 and ITA 121 is designed to integrate corporate and personal tax on Canadian-source dividends. Eligible dividends (from income taxed at the general corporate rate) are grossed up by 38% and attract a 15.02% federal dividend tax credit. Non-eligible dividends (from income taxed at the SBD rate) are grossed up by 15% and attract a 9.03% credit.

This system does not apply to foreign dividends. A US dividend received by a Canadian resident is not subject to the gross-up and does not receive the dividend tax credit. It is taxed at the full marginal rate as “other income.” This means US dividends bear a higher effective Canadian tax rate than Canadian eligible dividends, because the integration mechanism was designed for Canadian corporate tax already paid at source.

How are Canadian dividends taxed for US citizens?

A US citizen living in Canada who owns shares in a Canadian corporation faces both countries’ rules:

• Canadian return. The dividend is a Canadian-source eligible or non-eligible dividend. The gross-up and dividend tax credit apply. The effective rate on eligible dividends is approximately 31% to 39% depending on the province.
• US return. The same dividend is foreign-source income. If the Canadian corporation’s stock is publicly traded and qualifies as a qualified dividend, the US rate is 15% or 20% (plus 3.8% NIIT). The Canadian tax paid (after the dividend tax credit) is claimed as an FTC on Form 1116.

Because the Canadian effective rate on eligible dividends (31% to 39%) exceeds the US qualified dividend rate (18.8% to 23.8%), the FTC usually eliminates the US tax entirely, with excess credits. The coordination works in the taxpayer’s favor for Canadian dividends.

For dividends from a Canadian corporation that the US citizen controls (a CFC), the GILTI and Subpart F rules may have already included the corporate income on the US return before the dividend is paid. In that case, the dividend is a distribution of previously taxed earnings and profits (PTEP) and is excluded from US income to prevent double taxation. The Canadian withholding (if any, for a Canadian resident) or the gross-up treatment still applies on the Canadian return.

What about dividends inside registered accounts?

Account	US withholding on US dividends	Canadian withholding on Canadian dividends
RRSP/RRIF	0% (treaty exempt)	N/A (Canadian account, Canadian dividends)
TFSA	15% (no treaty exemption)	N/A
IRA/401(k)	N/A (US account, US dividends)	15% (treaty rate for non-resident)
Taxable account	15% (treaty rate)	15% (treaty rate for non-resident)

The RRSP exemption is the most valuable: US dividends inside an RRSP grow without US withholding. The TFSA’s lack of exemption is why financial advisors recommend holding Canadian stocks (or international stocks that are not US-sourced) inside the TFSA and US stocks inside the RRSP.

What should I do next?

If you hold investments that pay dividends across the border, check that the treaty form is on file with your broker or the paying corporation. Verify that your Canadian return separates foreign dividends (no gross-up) from Canadian dividends (gross-up and credit). Verify that your US return claims the FTC for Canadian withholding on Form 1116.

• Form 1116 and the foreign tax credit, the US credit for Canadian taxes
• US stocks in a TFSA, the withholding problem
• RRSP contributions as a US citizen, the treaty exemption for registered accounts
• RDTOH and cross-border dividend planning, the Canadian corporate refundable tax mechanism
• Currency conversion and exchange rates, converting dividends and withholding for reporting
• NIIT (3.8% net investment income tax), the US surtax that applies to dividend income
• Cross-border interest income and withholding, the 0% treaty rate on interest (different from dividends)
