Exchange-traded funds avoid capital gains distributions primarily through a mechanism called in-kind redemption, which lets the fund hand appreciated stocks directly to large institutional traders instead of selling them on the open market. Because no sale happens inside the fund, no taxable gain is triggered, and shareholders who simply hold their shares owe nothing at year-end. The scale of the advantage is striking: in recent years, roughly 97 percent of large-issuer ETFs distributed no capital gains at all, compared with about 64 percent of equity mutual funds that did distribute gains.
The In-Kind Redemption Mechanism
The tax advantage rests on a specific provision of federal tax law. Under 26 U.S.C. § 852(b)(6), when a regulated investment company distributes securities to a shareholder redeeming their shares, the fund does not recognize any gain on those securities, even if they have appreciated substantially since the fund bought them.1Office of the Law Revision Counsel. 26 USC 852 – Taxation of Regulated Investment Companies and Their Shareholders The handoff of stock is treated as a non-taxable event for the fund itself.
ETF shares are created and retired through a small group of large institutional firms called authorized participants, the only parties that transact directly with the fund. When an authorized participant wants to redeem a block of ETF shares (typically 25,000 to 50,000 at a time), it delivers those shares back to the fund and receives a basket of the fund’s underlying stocks in return, not cash.2Investment Company Institute. ETF Basics and Structure FAQs The fund hands over actual shares of the companies it holds rather than selling them and wiring money.
Creation works the same way in reverse. When an authorized participant creates new ETF shares, it delivers a basket of underlying stocks to the fund and receives ETF shares back. No cash moves in either direction, so nothing has to be sold.
The critical tax move happens inside the redemption basket. Fund managers can pick the specific tax lots with the lowest cost basis, meaning the shares purchased long ago at the cheapest prices, now carrying the largest embedded gains. By pushing those highly appreciated shares out of the portfolio through the in-kind transfer, the fund eliminates the embedded tax liability without ever triggering a sale. The authorized participant takes on the appreciated shares and any downstream tax consequences, and the remaining ETF shareholders are left with a cleaner portfolio.
Why Mutual Funds Cannot Do This
Traditional mutual funds lack the in-kind redemption structure, and the difference falls directly on shareholders. When mutual fund investors want their money back, the fund has to sell securities from its portfolio to generate cash. If those securities have risen in value, the sale creates realized capital gains, and the fund distributes those gains at year-end to every remaining shareholder, who each owe tax on the distribution. Investors who never sold a single share can still get a tax bill.3Vanguard. Understanding Capital Gains
ETF investors escape that problem because individual buyers and sellers trade with each other on the stock exchange, not with the fund. The overwhelming majority of ETF trading volume happens in this secondary market.4FINRA. Exchange-Traded Funds and Products When you sell your ETF shares, the fund’s portfolio is untouched. Your tax bill turns only on the difference between what you paid and what you received, and has nothing to do with what other shareholders do.
Heartbeat Trades and Index Rebalancing
Some ETFs push the in-kind mechanism further through a pattern known as a heartbeat trade. An authorized participant creates a large block of new ETF shares by delivering securities to the fund, and within a few days reverses the process by redeeming shares of roughly the same size. That rapid in-and-out gives the fund a fresh opportunity to load a redemption basket with its most appreciated holdings, flushing embedded gains out of the portfolio even when no genuine outflow is happening.
Index ETFs rely on heartbeat trades most often around rebalancing dates, when the fund has to adjust holdings to match changes in its underlying index. A rebalance would normally force the fund to sell appreciated stocks being dropped from the index, generating taxable gains. The heartbeat trade lets the fund shed those stocks through an in-kind redemption instead. The practice has drawn criticism and calls for regulatory reform, but it remains legal and widely used.
Low Turnover and Tax-Lot Selection
The in-kind structure works alongside a second, quieter tax feature: most ETFs are passively managed. They track an index by holding a fixed set of securities rather than trading actively. Fewer trades mean fewer chances for taxable gains to arise in the first place.
When adjustments do become necessary, managers use tax-lot identification to soften the impact. Every purchase of a stock is recorded as its own lot with a specific cost basis and date. When shares have to leave the portfolio, the manager selects the lowest-basis lots for the redemption basket, exporting the largest embedded gains. Over time, the average cost basis of what remains inside the fund drifts closer to current market prices, leaving less unrealized gain for future shareholders to worry about.
When ETFs Still Distribute Capital Gains
ETFs are not immune from capital gains distributions. Several situations can force gains to be realized inside the fund:
- Index rebalancing when the fund cannot fully offload appreciated shares through in-kind redemptions or heartbeat trades, and has to sell on the open market.
- Cash-settled redemptions, used by some ETF categories (particularly fixed-income funds and those holding assets that are difficult to transfer physically), which require the fund to sell securities to raise cash.
- Fund mergers and liquidations, which force a sale of the fund’s holdings and trigger any accumulated gains.
- Dividend and interest income, which is not a capital gain but still generates a distribution the shareholder owes tax on.
When capital gains distributions do occur, they are taxed at ordinary income rates for short-term gains and at the long-term capital gains rates of 0, 15, or 20 percent depending on your taxable income and filing status.5Internal Revenue Service. Topic No. 409, Capital Gains and Losses Higher earners may also owe an additional 3.8 percent net investment income tax if their modified adjusted gross income exceeds $200,000 (single) or $250,000 (married filing jointly). Those thresholds are set by statute and are not adjusted for inflation.6Internal Revenue Service. Topic No. 559, Net Investment Income Tax
ETF Categories Where the In-Kind Advantage Does Not Apply
The § 852 in-kind redemption tax benefit is a feature of regulated investment companies holding securities. Several popular ETF categories sit outside that structure entirely, and their tax treatment looks nothing like a stock ETF’s.
Physical Commodity ETFs
ETFs that hold physical gold, silver, or other precious metals are organized as grantor trusts, not regulated investment companies. The IRS treats gains from these funds as collectibles gains, which carry a maximum long-term federal rate of 28 percent, well above the 20 percent top rate on stock ETFs.7Office of the Law Revision Counsel. 26 USC 1 – Tax Imposed Short-term gains are taxed as ordinary income. Because these trusts hold physical metal rather than securities, § 852’s in-kind redemption benefit does not reach them.
Spot Cryptocurrency ETFs
Spot bitcoin and other cryptocurrency ETFs also use a grantor trust structure, and they settle redemptions in cash rather than in kind. That raised early concerns about capital gains being passed through to non-redeeming shareholders. Under the grantor trust rules, however, each shareholder is treated as owning a proportional share of the trust’s assets directly. When a redemption occurs, the resulting sale is attributed only to the redeeming shareholder, and other investors in the fund should not receive a capital gains distribution from it.
Futures-Based ETFs
ETFs holding regulated futures contracts, including many commodity, volatility, and leveraged products, fall under Section 1256 of the tax code. Gains and losses receive a fixed 60/40 split: 60 percent long-term and 40 percent short-term, regardless of how long the fund held the contract.8Office of the Law Revision Counsel. 26 USC 1256 – Section 1256 Contracts Marked to Market These contracts are marked to market at year-end, so unrealized gains are taxed as if the positions were closed on December 31, even when the fund made no actual trades. The 60/40 rate treatment is generally favorable compared with pure short-term rates, but the mark-to-market rule means gains cannot be deferred simply by holding.
