In-Kind Redemptions and Tax Efficiency

When a mutual fund needs to raise cash for redemptions, it typically has to sell some of its holdings on the open market. If those holdings have appreciated since the fund bought them, that sale realizes a capital gain — and by law, the fund has to pass realized gains through to its remaining shareholders each year as a taxable distribution, even to shareholders who never sold a single share themselves. This is one of the more counterintuitive features of fund investing: you can owe tax on a fund simply for holding it, because other investors redeemed and the fund had to sell to pay them.

How ETFs sidestep this

ETFs are built differently: large redemptions happen not by an ordinary investor selling shares back to the fund for cash, but through authorized participants who hand in a big block of ETF shares and receive, in exchange, a basket of the actual underlying securities the fund holds — an in-kind redemption. Because handing over securities directly isn't treated as a sale by the fund, no capital gain is realized in the process, even if those securities have appreciated enormously since the fund first bought them. The fund can also choose which specific shares (often its lowest-cost-basis, most appreciated ones) to hand out in the basket, effectively using redemptions to flush out embedded gains from the portfolio entirely, rather than realizing them.

A concrete example: an ETF bought a stock years ago at $20 that's now worth $100. A mutual fund holding the same stock would realize an $80-per-share gain if it had to sell that stock to raise redemption cash, triggering a taxable distribution to remaining shareholders. An ETF facing a similar redemption instead hands that exact stock, at its current $100 value, directly to the authorized participant — no sale occurs, no gain is realized, and the appreciated position simply leaves the fund's books along with the redeeming investor.

What this means in practice

This mechanism is a major reason ETFs have historically distributed far smaller (often zero) taxable capital gains compared to actively managed mutual funds running similar strategies, even setting aside any difference in turnover. It isn't that ETF gains disappear — an investor who sells their own ETF shares still owes capital gains tax on their personal profit — it's that the gains embedded inside the fund's portfolio from other investors' activity don't get forced out as an annual taxable event for everyone else.
