How to buy US stocks from Canada: US dividend withholding tax in RRSP and TFSA explained

Canadians can buy US-listed stocks directly through most Canadian brokerages, and the tax treatment of US dividends depends on which account type you use. This guide walks through the practical steps and the withholding tax rules that matter for Canadian value investors.

1. Open a brokerage account that offers access to US markets. Most Canadian online brokers allow you to trade US stocks in USD or CAD, either through a US-dollar sub-account or via automatic currency conversion.
2. Convert your Canadian dollars to US dollars. You can either use your broker's currency conversion service or use the "Norbert's gambit" with an interlisted ETF to save on spreads, though the latter takes more steps.
3. Buy the US stock using its ticker symbol on the NYSE, Nasdaq, or another US exchange. Place a regular order just as you would for a Canadian stock.
4. Understand the dividend withholding tax. If the company pays a dividend, the US Internal Revenue Service (IRS) generally withholds a portion of that dividend before it reaches you. The rate depends on your account type and the Canada-US tax treaty.
5. File the correct forms. For most accounts, your broker will ask you to complete a W-8BEN form to certify you are a Canadian resident and claim the treaty rate.

How to buy US stocks from Canada in practice

The easiest way is to use your existing Canadian brokerage account. Most large banks and independent online brokers offer US trading. You do not need a US brokerage account, a US address, or a US social security number to trade US stocks.

When you buy a US-listed stock, the transaction is settled in US dollars. If your account holds only Canadian dollars, the broker will convert currency at their exchange rate, which may include a markup. Some brokers let you open a separate USD account so you can hold US dollars and avoid repeated conversions.

You can also buy US stocks through a Canadian-listed ETF that holds the same companies, which avoids direct currency conversion and the US withholding tax complication in some cases. But if you want to own individual US stocks directly, direct purchase through a US exchange is the standard route.

US dividend withholding tax for Canadians: the basics

When a US company pays a dividend, the IRS normally requires a 30% withholding tax on that payment to foreign investors. The Canada-US tax treaty reduces this rate to 15% for Canadian residents who complete IRS Form W-8BEN. That 15% is withheld before the dividend is paid into your account, so you never see the full dividend amount.

This 15% withholding applies in most taxable (non-registered) brokerage accounts. The withheld amount is treated as foreign tax paid, and you may be eligible for a foreign tax credit on your Canadian tax return. That credit can reduce the double taxation, but it does not eliminate the cost if your Canadian tax rate is lower than the US rate.

RRSP US stock withholding tax: the treaty exemption

The Canada-US tax treaty contains a special rule for registered retirement savings plans. The US recognizes an RRSP as a qualifying pension plan, so dividends received inside an RRSP are exempt from US withholding tax entirely. This means you receive the full dividend amount, with no 15% deduction.

If you hold US stocks inside an RRSP, you do not need to worry about US dividend withholding. That makes an RRSP the most tax-efficient account for US dividend stocks, because the dividend is not reduced by the IRS and is also sheltered from Canadian tax until withdrawal.

Note that this exemption applies only to a true RRSP, not to a Registered Retirement Income Fund (RRIF) at the same level. RRIFs also qualify under the treaty as pension plans, but you should confirm with your broker that your account type is recognized. In practice, most major Canadian brokers automatically apply the treaty exemption to RRSPs.

TFSA US dividends tax: no treaty exemption

The Tax-Free Savings Account (TFSA) is not considered a pension plan under the Canada-US tax treaty. As a result, US dividends paid into a TFSA are still subject to the 15% US withholding tax. The TFSA shelter does not apply to this US-source tax, because the IRS does not recognize the TFSA as a tax-sheltered pension.

The 15% withheld is also not recoverable as a foreign tax credit, because the TFSA itself is not taxable in Canada and you cannot claim a credit for taxes paid on income that is not taxable in Canada. This makes US dividend stocks less tax-efficient inside a TFSA than inside an RRSP or a taxable account.

If you want US dividend income in a TFSA, an alternative is to hold a Canadian-listed ETF that invests in US stocks. The ETF itself may be subject to US withholding on the dividends it receives, but the tax drag is embedded in the ETF and not directly visible to you. In some cases, Canadian wrap ETFs that use derivatives can reduce this drag, but the rules are complex.

Canada US stock tax treaty: how the 15% withholding works

The relevant part of the treaty is Article X (Dividends). It allows the US to tax dividends paid to Canadian residents, but caps the rate at 15% for most individuals. To get this reduced rate, you must provide the US broker with a valid W-8BEN form. The form states that you are a resident of Canada for tax purposes and do not have a US permanent establishment.

Your broker will ask you to complete this form online when you open an account or when you first trade US securities. The W-8BEN is valid for three years and must be renewed. If you do not provide it, the US may withhold the full 30% default rate.

For RRSPs, the treaty goes further. Under the pension article, the US does not tax dividends paid to an RRSP. The broker recognizes the RRSP as a qualifying entity, so US withholding is set to 0%. You may need to indicate on the form that the account is an RRSP.

Does the type of US stock matter?

All US-listed stocks pay dividends in US dollars. The withholding tax rules apply to ordinary dividends and, in most cases, to qualified dividends as well. Canadian residents do not receive the lower US qualified dividend rate; the treaty rate of 15% is the standard for all Canadian-resident individuals.

REITs (real estate investment trusts) and certain other US entities have a different withholding rule. Distributions from a US REIT may be treated as ordinary income and can be subject to a higher withholding rate under the treaty, often 15% but in some cases up to 30% if the distribution is not a dividend. If you are buying REITs, confirm the specific treatment with a tax professional or your broker.

Currency conversion and trading costs

When you trade US stocks, you are exposed to the US-Canadian exchange rate. Your Canadian-dollar returns will rise or fall with the currency. That currency exposure is separate from the stock's return in USD.

Some brokers charge a flat fee per trade, while others charge a percentage commission. Compare the fees for US trades, the currency conversion markup, and any annual account fees. For frequent traders, even small markup differences add up.

The bottom line

To buy US stocks from Canada, you can use your existing brokerage account, convert to USD, and place a trade on a US exchange. The tax treatment of dividends depends on the account: an RRSP is fully exempt from US withholding tax, a TFSA is not exempt and offers no credit for the 15% withheld, and a taxable account is subject to 15% withholding but may qualify for a foreign tax credit. Choose the account type based on your investment goals and tax situation.
