Does a Canadian-listed S&P 500 fund escape US withholding tax?

This comes up constantly, and the intuition behind it is completely reasonable. You have read that an RRSP is exempt from US withholding tax under the Canada–US treaty. You hold a US equity fund. The fund trades in Canadian dollars on the TSX. So you are fine, surely?

Unfortunately not, and the reason is a small piece of plumbing that has a large effect.

The question is who holds the US stock

The treaty exemption applies to the holder of the US security. That is the crux of the whole thing.

When you buy a US-domiciled stock directly inside your RRSP, you are the holder. Your account is an RRSP. The exemption applies, the withholding is waived, and you receive the full dividend.

When you buy a Canadian-listed ETF that holds US stocks, the fund is the holder. The fund is not an RRSP. The US withholds 15% from the dividends flowing into it, before your account is any part of the story. By the time the money reaches you, the tax is already gone — and there is no line item showing you it happened.

The wrapper you hold the fund in cannot reach back and undo something that occurred one level up.

So how many layers are there?

This is where it gets genuinely fiddly, because Canadian ETFs come in a few structures and they behave differently.

A Canadian fund holding US stocks directly. One layer of withholding, taken at the fund. Unrecoverable in a TFSA. Unrecoverable in an RRSP too — the exemption does not apply, because the fund is the holder.

A Canadian fund that holds a US-listed ETF, which holds the stocks. Two layers. The US ETF has withholding taken on its way in, and then the Canadian fund has withholding taken on the distribution it receives from the US ETF. This is the worst case, and it is more common than you would expect.

A US-listed ETF held directly in your RRSP. One layer, and the treaty waives it. This is the only combination that gets you the full exemption.

That last line is the whole practical takeaway. If the exemption matters to you, you need to hold the US-domiciled fund itself, in an RRSP, not a Canadian wrapper around it.

Is it worth restructuring for?

Honestly — sometimes, and less often than the internet suggests.

The cost is 15% of the dividend, not 15% of your money. On a US broad-market fund yielding around 1.3%, that is roughly 0.20 percentage points a year. Real, but small enough that it can be outweighed by:

• Currency conversion costs. Buying a US-listed fund means converting CAD to USD. If your broker charges 1.5% on the spread, you have just paid seven years of withholding tax to save it. Norbert’s gambit avoids most of that, but it is a manual process with settlement delays and it is not free either.
• Simplicity. A single Canadian-listed fund in one currency is easier to hold, rebalance and explain to whoever inherits it.
• Whether you have RRSP room at all. The exemption only exists there. If your RRSP is full or small, the question is moot.

On a high-yield US holding the arithmetic changes sharply. Fifteen percent of a 4% yield is 0.60 points a year, and now it is worth the trouble.

So the honest answer is that it scales with yield. For a low-yield growth fund, do not contort your portfolio over it. For US income holdings, it is one of the few genuinely free improvements available.

What about a TFSA?

Worse, and worth being blunt about. A TFSA gets no exemption at any layer, and because there is no Canadian tax payable inside it, there is no foreign tax credit to claim either. The 15% is simply gone with nothing to offset it against.

A non-registered account is, counterintuitively, better than a TFSA on this specific dimension — you pay Canadian tax on the dividend, but you can generally recover the US withholding as a foreign tax credit.

That produces the ordering most people find surprising: for a directly-held US dividend payer, RRSP first, non-registered second, TFSA last.

The short version

• The treaty follows the holder of the US security, not the account you hold the fund in.
• A Canadian-listed fund is the holder, so the withholding happens above you and cannot be recovered.
• Only a US-domiciled holding, held directly in an RRSP or RRIF, gets the exemption.
• The cost scales with yield: negligible on a growth fund, meaningful on an income one.
• A TFSA is the worst home for US dividends. There is nothing to credit the withholding against.

If you want to see what the drag looks like on a specific holding, the formula breaks a headline yield down into what reaches you, foreign tax included. And TFSA vs RRSP for dividends covers the wider placement question.
