What is a phantom distribution?
A phantom distribution — also called a reinvested or notional distribution — is a taxable capital-gains distribution that an ETF declares but reinvests instead of paying in cash. You receive no money, but you owe tax on the distribution for the year, and your adjusted cost base rises by the same per-unit amount.
It happens when a fund realizes capital gains internally — for example when it rebalances its holdings — and passes them through to unitholders at year end without an actual cash payout. It typically shows up in box 21 of your T3.
Why ignoring it makes you pay tax twice
This is the trap. You already pay tax on the phantom distribution for the year it is declared. That distribution also increases your cost base — but only if you record it. If you never adjust your ACB, then later when you sell, your cost base is too low, your gain is too high, and you pay capital-gains tax again on the same amount you were already taxed on.
Phantom distribution vs. return of capital
These are opposite adjustments and are easy to confuse:
| Phantom distribution (box 21) | Return of capital (box 42) | |
|---|---|---|
| Taxed now? | Yes — as a capital gain | No — not immediate income |
| Effect on ACB | Raises it | Lowers it |
| If ignored | You overpay later (double tax) | You understate a later gain |
Return of capital that drives your ACB to zero becomes an immediate capital gain from that point on.
Where the numbers come from
Fund providers publish the per-unit breakdown of each distribution — typically via the CDS Innovations tax breakdown posted early in the year, and reflected on your T3. The amounts are per unit, so you scale them to the number of units you held on the relevant record date. For common Canadian ETFs you can look these up on our ETF distributions index.
