Dividends Across the Border: Treaty Withholding Rates, the Canadian Gross-Up, and Why the Credit Rarely Matches

Short version: Qualified Dividends From Canadian Companies Explained

Dividends are the cross-border income most people hold and least understand. The source country withholds at a treaty rate, the residence country taxes the gross dividend and gives a credit for the withholding, and the two countries' domestic dividend regimes (Canada's gross-up and credit, the US's qualified dividend rate) interact with the credit in ways that leave a residual in one direction and excess credit in the other. For a Canadian holding US stocks or an American holding Canadian ones, the answer depends on which country, which account, and which rate.

Key takeaways

• Treaty rates: 15% withholding on portfolio dividends; 5% where the recipient is a company owning at least 10% of the payer's voting stock. Without the treaty, both countries withhold 25% (Canada) or 30% (US).
• Canadian resident, US dividends: 15% US withholding (with Form W-8BEN on file); the gross dividend is taxable in Canada at ordinary rates with no gross-up or dividend tax credit (foreign dividends do not qualify), and the 15% is claimed as a foreign tax credit on Form T2209. Inside an RRSP, US dividends are exempt from US withholding under the treaty; inside a TFSA they are not.
• US resident, Canadian dividends: 15% Canadian Part XIII withholding (with Form NR301 on file); the gross dividend is taxable in the US, generally as a qualified dividend at 0%, 15%, or 20% because Canada is a treaty country, and the 15% is claimed as a foreign tax credit on Form 1116 in the passive basket.
• Corporate recipients: a Canadian corporation owning 10% or more of a US payer gets the 5% rate, and vice versa; Canadian corporations receiving US dividends face FAPI or exempt surplus rules depending on the activity.
• The credit rarely matches: a Canadian at a 53.5% marginal rate pays 15% to the US and 38.5% to Canada net of credit; an American at the 15% qualified rate pays 15% to Canada and nothing further in the US, but may have excess passive-basket credit.

Canadian residents holding US stocks

The US withholds 15% under the treaty if the broker has a Form W-8BEN on file; without it, 30%. The dividend is reported in Canadian dollars on the T1 as foreign investment income, taxed at ordinary rates with no gross-up and no dividend tax credit. The 15% withholding is a foreign tax credit on Form T2209, limited to the Canadian tax on the US dividend, which is almost always higher; the credit is fully usable.

By account: in an RRSP or RRIF, the treaty exempts US dividends from withholding (Article XXI(2)), so US stocks are efficient there. In a TFSA, the US withholds 15% and Canada gives no credit because the TFSA is not taxable; the 15% is a permanent cost. In a non-registered account, the 15% is credited.

US residents holding Canadian stocks

Canada withholds 25% under Part XIII, reduced to 15% under the treaty on a Form NR301 filed with the payer or broker. The dividend is reported on the 1040; dividends from a Canadian corporation whose shares trade on a US exchange, or from a corporation resident in a treaty country, are qualified dividends taxed at 0%, 15%, or 20% plus the 3.8% NIIT. The 15% Canadian withholding is a foreign tax credit on Form 1116 in the passive basket, limited to the US tax on foreign passive income; for a taxpayer in the 15% qualified bracket, the credit exactly offsets, and for one in the 0% bracket, it is excess credit that carries forward.

Inside a US IRA or 401(k), Canada exempts dividends from withholding under the treaty's pension provisions if the plan is recognized; brokers do not always apply it, and a 15% withholding in an IRA is a permanent cost because the IRA is not taxable.

The Canadian gross-up and credit

Canadian eligible dividends received by a Canadian resident are grossed up by 38% and taxed with a dividend tax credit, producing an effective top rate of about 39% in Ontario versus 53.5% on ordinary income. That mechanism applies only to dividends from Canadian corporations to Canadian residents. A US resident receiving Canadian dividends gets none of it (the 15% withholding is the whole Canadian tax); a Canadian resident receiving US dividends gets none of it (foreign dividends are ordinary income).

Corporate holders

A Canadian corporation receiving dividends from a US corporation in which it owns 10% or more gets the 5% treaty rate; the dividend is exempt surplus if paid from active business earnings (no further Canadian tax) or taxable surplus with a credit otherwise. A US corporation receiving dividends from a Canadian corporation in which it owns 10% or more gets the 5% rate and, under US law, a 100% dividends-received deduction for foreign-source dividends from 10%-owned foreign corporations.

Worked example

A Toronto resident at the top marginal rate holds $200,000 of US dividend stocks yielding 3% in a non-registered account and the same in an RRSP.

• Non-registered. $6,000 of dividends; US withholds $900; Canada taxes $6,000 at 53.5% ($3,210) less a $900 credit: $2,310. Total tax $3,210, or 53.5%.
• RRSP. $6,000 of dividends; no US withholding under the treaty; no Canadian tax until withdrawal.

An American in Florida at the 15% qualified rate holds $200,000 of Canadian bank shares yielding 4%.

• Non-registered. $8,000 of dividends; Canada withholds $1,200 (NR301 on file); US tax $1,200 plus NIIT $304 less a $1,200 credit: $304. Total tax $1,504, or 18.8%.

Official sources

"The tax so charged shall not exceed: (a) 5 per cent of the gross amount of the dividends if the beneficial owner is a company which owns at least 10 per cent of the voting stock of the company paying the dividends; (b) 15 per cent of the gross amount of the dividends in all other cases." — Canada-United States Tax Convention, Article X(2), https://www.canada.ca/en/department-finance/programs/tax-policy/tax-treaties/country/united-states-america-convention-consolidated-1980-1983-1984-1995-1997.html

"The most common types of Canadian income subject to Part XIII tax are: dividends, rental and royalty payments, pension payments [...] The usual Part XIII tax rate is 25% unless a tax treaty between Canada and your home country reduces this rate." — Canada Revenue Agency, Non-residents of Canada, https://www.canada.ca/en/revenue-agency/services/tax/international-non-residents/individuals-leaving-entering-canada-non-residents/non-residents-canada.html

Practitioner note

The account matters more than the rate. US dividend stocks belong in a Canadian resident's RRSP, not the TFSA, because the treaty exemption applies to one and not the other. And the Form W-8BEN or NR301 has to be on file with the broker before the first dividend; without it, the withholding is 30% or 25% and the excess is recoverable only by filing a return in the source country.
