Why ETF tax efficiency matters
Most investors compare ETFs by MER alone. But in a taxable account, the tax drag from distributions, withholding tax, and capital gains turnover often costs more than the fee difference. A 0.24% MER ETF that distributes heavily can cost you more after tax than a 0.20% ETF that retains income internally.
Tax efficiency matters most in non-registered accounts. Inside a TFSA, all distributions are sheltered. Inside an RRSP, gains are deferred. But in a taxable account, every distribution triggers a tax event — and the structure of the ETF determines how much leaks out each year.
XEQT vs VEQT: the biggest comparison
Both are 100% equity, globally diversified, all-in-one ETFs. Here is how they compare on tax-relevant dimensions:
| XEQT (iShares) | VEQT (Vanguard) | |
|---|---|---|
| MER | 0.20% | 0.24% |
| Underlying structure | Fund-of-funds (holds iShares ETFs) | Fund-of-funds (holds Vanguard ETFs) |
| Canada allocation | ~25% | ~30% |
| US allocation | ~45% | ~43% |
| Withholding tax layer | Two layers on US/intl dividends | Two layers on US/intl dividends |
| Distribution yield | ~1.7% | ~1.8% |
Tax efficiency verdict: Nearly identical. XEQT has a 0.04% MER advantage. VEQT tilts slightly more toward Canada (which avoids withholding on domestic dividends). The difference in after-tax returns is negligible — pick either and stay consistent.
Canadian-listed vs US-listed ETFs
Holding US-listed ETFs (VOO, VTI, SCHD) instead of their Canadian wrappers (VFV, VUN, XUU) can save you money — but only in the right account:
| Account | Canadian-listed (VFV) | US-listed (VOO) | Winner |
|---|---|---|---|
| RRSP | 15% US withholding lost in wrapper | 0% withholding (treaty) | VOO — saves ~0.35% on a 2.3% yield |
| TFSA | 15% lost in wrapper, not recoverable | 15% withheld, not recoverable | Tie — both lose 15% |
| Non-registered | 15% lost in wrapper (no FTC) | 15% withheld (claim FTC) | VOO — FTC recovers the withholding |
The catch: Buying US-listed ETFs requires converting CAD to USD. Broker FX spreads (1.5–2.5% at most brokers) can wipe out years of withholding tax savings. Use Norbit's Gambit (cost ~0.1%) to make this worthwhile.
Understanding withholding tax layers
Foreign dividends passing through fund structures face multiple layers of withholding:
- Level 1: The foreign country withholds tax at source (e.g., US withholds 15% on dividends paid to a foreign fund)
- Level 2: If the Canadian ETF holds a US-listed ETF (wrapper structure), a second layer of withholding applies when dividends flow from the US ETF to the Canadian fund
Canadian ETFs that hold US stocks directly (like XUS, which holds 500 US stocks) avoid Level 2. Canadian ETFs that hold a US-listed ETF as a wrapper (like VFV, which holds VOO) pay both levels.
In an RRSP: The Canada-US treaty waives Level 1 for US-listed ETFs. But it does NOT waive Level 2 when a Canadian wrapper holds the US ETF. This is why VOO in an RRSP beats VFV in an RRSP.
Swap-based ETFs: maximum tax efficiency
Some Canadian ETFs use total return swap structures to eliminate distributions entirely. Instead of receiving dividends from the underlying stocks, the fund enters a swap agreement with a counterparty who delivers the total return (price + dividends) synthetically.
Result: Zero distributions in a non-registered account. All return comes as capital gains when you sell — deferred until sale and taxed at only 50% inclusion.
Examples of swap-based ETFs:
- HXT (Horizons S&P/TSX 60 Total Return) — swap-based version of XIU
- HXS (Horizons S&P 500 Total Return) — swap-based version of VFV/ZSP
- HSAV (Horizons Cash Maximizer) — swap-based high-interest savings
Caveat (2024+ rule change): In the 2023 federal budget, the government announced that funds using derivative-based strategies to convert income to capital gains would be subject to new rules. Some swap-based ETFs have restructured to comply, and the tax efficiency advantage may be reduced. Check the fund's most recent distribution history before relying on zero distributions.
Distribution types and their tax cost
Not all ETF distributions are taxed equally. In a non-registered account:
| Distribution type | Tax treatment | Effective rate (Ontario, $100K income) |
|---|---|---|
| Canadian eligible dividends | Gross-up + DTC | ~25% |
| Capital gains | 50% inclusion | ~22% |
| Return of capital | Reduces ACB (deferred) | 0% now, gain later |
| Foreign income / interest | Fully taxable | ~43% |
ETFs with heavy foreign income or interest distributions are the least tax-efficient in a taxable account. Prefer these in registered accounts (RRSP, TFSA) and keep capital-gain-oriented ETFs in non-registered.
Practical framework for choosing
- TFSA: Tax efficiency is irrelevant — everything is sheltered. Pick the lowest MER or the best risk-adjusted return.
- RRSP: Consider US-listed ETFs for US equity exposure (saves withholding tax). For everything else, Canadian-listed is fine.
- Non-registered: Tax efficiency matters most here. Prefer ETFs with low turnover, capital-gain-oriented distributions, and consider swap-based structures for bond/fixed-income exposure.
- Simplicity over optimization: For portfolios under $200,000, the tax savings from optimizing ETF structure is often $200–$500/year. An all-in-one ETF like XEQT or VEQT in every account is a perfectly valid strategy.
