The Couch Potato strategy calls for a significant allocation to US and international stocks. When you live in a country with a small, poorly diversified stock market, global diversification is extremely important. But it does carry a price in the form of foreign withholding taxes.

Many countries levy a tax on dividends paid to foreign investors: the rate varies, but for US stocks it is 15%. (Foreign withholding taxes do not apply to capital gains.) With broad-based US index funds now yielding about 2%, the withholding tax amounts to an additional cost of 30 basis points. As you can see, the impact of withholding taxes can be far greater than that of management fees, which get a lot more attention.

To learn how much tax is withheld by your fund, click the “Distributions” tab on its web page and look under the heading “Foreign Tax Paid.” Here’s what the table looks like for the iShares S&P 500 (XSP). Notice the amount of tax paid for 2011 ($0.04388 per share) is approximately 15% of the foreign income received ($0.26866):

Investors and advisors are often unaware of how foreign withholding taxes affect returns, and the reason is simple: they’re damned complicated. The amount of tax you pay varies with the type of account (taxable, RRSP, TFSA) and the structure of the fund.

What type of account?

Let’s start with account types. If you hold foreign stocks in a non-registered (taxable) account, withholding taxes always apply: if a company pays a 20-cent dividend each quarter, only 17 cents ends up in your account. The good news is the amount you paid will appear on your T3 and T5 slips and you can recover some or all of it by claiming a foreign tax credit on your return.

The other key point is that Canada has tax treaties with the US and many other countries that have agreed to waive withholding taxes on stocks held in registered retirement accounts, including RRSPs, RRIFs and Locked-In Retirement Accounts (LIRAs).

Note this exemption does not apply to Tax-Free Savings Accounts (TFSAs).

What type of fund?

The structure of the fund you’re using for your foreign investments is also extremely important—and even more confusing.

First consider Canadian funds that hold foreign securities directly, which includes mutual funds such as the TD e-Series and some (but surprisingly few) US and international equity ETFs on the Toronto Stock Exchange. Because these funds hold the individual stocks directly, the managers can track the withholding taxes and report them (through a T3 slip) to investors who hold the funds in a taxable account. That allows the investor apply for the foreign tax credit.

However, if you hold these funds in an RRSP, you forfeit the exemption you would otherwise receive on foreign withholding taxes. That’s because the fund itself pays the withholding taxes: you don’t pay it directly. And because you’re investing in an RRSP, the fund won’t issue a T3 slip that would allow you to recover it.

With US-listed ETFs the US withholding tax is recoverable in a non-registered account: you’ll receive a T5 slip that specifies the amount paid. Better yet, if you hold these ETFs in an RRSP, you’re exempt from US withholding taxes. The downside is that when a US-listed ETF holds international stocks there’s an extra layer of withholding tax applied by the stocks’ native countries. There is no way to recover that tax.

The final category is Canadian-listed ETFs that hold US-listed ETFs. These include a number of Canadian iShares and Vanguard funds. Rather than holding their underlying stocks directly, they simply hold units of their New York–listed counterparts.

When you hold these in a taxable account, you can recover taxes withheld by the US-listed ETF, but those withheld by non-US countries are not recoverable. In an RRSP, you may incur two levels of withholding tax and neither is recoverable, which makes this structure particularly tax-inefficient for international equities.

Confused yet? You’re not alone. To provide you with a handy reference I’ve broken down all of the categories, provided examples of common funds in that category, and summarized the tax implications in each type of account.
