The 15% almost nobody notices
When a US company pays you a dividend, the American government takes a cut before it reaches your account. The statutory rate is 30%. Thanks to the Canada–US tax treaty, Canadians get it reduced to 15% — automatically, provided your broker has the standard paperwork on file, which any Canadian brokerage does by default.
So a US dividend of $100 typically lands as $85. That's the part most people know, if they know any of it.
Here's the part that matters far more: whether you ever get that $15 back depends entirely on which account the stock sits in — and the ranking surprises almost everyone. The tax-free account is the one where the tax is permanent. The taxable account is the one where you get it back. And the ETF wrapper you bought specifically to keep things simple may be quietly costing you the money in every account you own.
One disclaimer before the details: this is general information, not tax advice, and cross-border tax has more edge cases than any single article can cover. Anything with real money attached is worth running past an accountant.
RRSP: zero, and it's the only zero
The treaty contains a specific carve-out for retirement accounts. US dividends paid into an RRSP or RRIF are exempt from withholding entirely — not reduced, exempt. Your $100 dividend arrives as $100.
This is one of the genuinely free wins in Canadian investing, and it comes with one strict condition: the exemption applies to US-listed securities held directly in the plan. Buy shares of a US company on a US exchange inside your RRSP, or a US-listed ETF holding US stocks, and you get the full amount. Hold something that reaches US stocks through a Canadian wrapper and you don't — more on that below, because it's where most people lose the benefit without realizing they had it.
Worth noting the exemption covers US dividends specifically. A US-listed ETF holding international stocks still loses foreign tax at the fund level before the money ever reaches your RRSP, and no treaty fixes that layer.
TFSA: 15%, gone for good
Now the counterintuitive one. The treaty's retirement-account exemption doesn't extend to TFSAs — the account didn't exist when the relevant provisions were written, and it isn't recognized as a pension plan. So US dividends into a TFSA get the standard 15% haircut.
That alone would be merely unfortunate. What makes it permanent is the mechanism for recovering foreign withholding: the foreign tax credit, which offsets Canadian tax payable on that income. A TFSA generates no Canadian tax payable. There is nothing for the credit to offset, so there's no credit — the 15% is simply gone.
The result is the arrangement most Canadians would never guess: on US dividends, the tax-free account is the one that loses to withholding permanently, while the taxable account gets the money back. Same logic applies to the RESP, RDSP and FHSA — none of them are treaty-recognized retirement plans, so all of them absorb the 15% with no recovery.
To size it: a 3% US dividend yield inside a TFSA gives up about 0.45% a year, forever. That's roughly double the entire management fee of a cheap Canadian index ETF — a real cost, quietly compounding, from a decision nobody consciously made.
Taxable: 15% withheld, then credited back
In a non-registered account the 15% is withheld the same way, but the story doesn't end there. You report the gross dividend as income on your Canadian return and claim a foreign tax credit for the US tax already paid — so provided you have enough Canadian tax payable, the withholding is effectively neutralized.
The catch is that US dividends in a taxable account are fully taxable as foreign income at your marginal rate. No dividend tax credit — that's reserved for dividends from Canadian corporations, which is a meaningful reason Canadian income investors tilt domestic in non-registered accounts. So the withholding gets refunded, but the underlying income is taxed less favourably than a Canadian dividend would be.
The practical hierarchy that falls out of all this, for US dividend payers specifically: RRSP first (no withholding at all), taxable second (withheld but recoverable), TFSA last (withheld and gone). Which is roughly the opposite of how most people fill their accounts.
The wrapper trap: where Canadians actually lose this
Here's the part with the most money in it, and it applies directly to income ETFs.
The RRSP exemption requires the plan to be the one receiving the US dividend. When you own a Canadian-listed ETF that holds US stocks, the fund receives the dividend, not your RRSP — so the US withholds 15% at the fund level before your ETF ever distributes anything to you. The treaty exemption doesn't reach through the wrapper. You lose the 15% inside your RRSP, exactly as you would in a TFSA, and you never see it on a statement because it happened one level down.
It gets worse with layered products. A Canadian-listed ETF that holds a US-listed ETF that holds US stocks creates two withholding layers — one where the US ETF collects the dividends, another where the Canadian fund collects from the US ETF. Two haircuts, stacked, invisible.
In a non-registered account, foreign tax paid at the fund level is generally reported to you and can support a foreign tax credit, so the layered structure is less punishing. In registered accounts, it's pure leakage. The rule of thumb worth remembering: if you want US dividend exposure inside an RRSP, own it US-listed and direct. Convenience wrappers are convenient everywhere else.
What this means for covered-call and income funds
Two wrinkles specific to the funds this site spends most of its time on.
Option premium isn't a dividend. The premium a covered-call fund collects from writing options isn't US dividend income, so US dividend withholding doesn't apply to that slice. For a fund with US underlying holdings, only the dividend portion of what it collects takes the 15% hit — which softens the wrapper problem relative to a plain US dividend ETF, though it doesn't eliminate it. It also means the withholding drag varies with how much of the distribution is premium versus dividends, which changes year to year.
"Tax-free 10%" oversells it. A high-yield fund with US underlying, held in a TFSA, is quietly surrendering part of its dividend component to a foreign government before the distribution is even calculated. The distribution is tax-free to you in the sense that Canada won't tax it. It isn't untouched. And since a big distribution isn't the same thing as a big return, the account-type advantage matters less than which fund you picked in the first place — an unrecovered 15% on the dividend slice is real, but it's small compared to what a manufactured payout can cost you in surrendered growth.
Canadian-domiciled funds holding Canadian companies sidestep the entire issue: no US involvement, no withholding, and in a taxable account the dividend tax credit applies. That's not an argument for home bias as a strategy — it's just worth knowing that the tax friction you've been reading about is specific to reaching across the border, and much of what we cover doesn't cross it.
The short version
US dividends into an RRSP: nothing withheld, provided you hold the security US-listed and direct. Into a taxable account: 15% withheld, recoverable through the foreign tax credit, though the income itself is taxed at full rates. Into a TFSA, RESP, RDSP or FHSA: 15% withheld, unrecoverable, permanently.
And in every account, a Canadian-listed wrapper holding US stocks loses the 15% at the fund level before the money reaches you — which quietly cancels the RRSP advantage that most of the internet's account-placement advice assumes you're getting.
None of this should drive a portfolio. Asset allocation and fund quality matter more than tax placement, and placing a bad fund optimally is still owning a bad fund. But once you've decided what to hold, where you hold it is free money or a permanent leak, and the difference is one decision made once.
