ETFs vs. Mutual Funds: A Tax Efficiency Advantage

This discussion, hosted by Ivana Hampton with guest Brian Armor from Morningstar Research Services, explores how Exchange Traded Funds (ETFs) offer significant tax advantages over traditional mutual funds, primarily due to their structural differences in trading and transaction treatment.

The Mechanics of Tax Efficiency

The core of the tax efficiency difference lies in how ETFs and mutual funds handle the sale of underlying assets and the subsequent distribution of capital gains.

Mutual Funds:
- Trade only once a day at Net Asset Value (NAV).
- When investors redeem shares, mutual funds may need to sell underlying holdings to generate cash, potentially realizing capital gains.
- These realized capital gains are then distributed to all shareholders, creating a tax liability even if the individual investor didn't sell their shares.
ETFs:
- Trade throughout the day on stock exchanges like individual stocks.
- A two-tiered trading system exists:
  - Secondary Market: Investors trade ETF shares with each other.
  - Primary Market: Authorized Participants (APs) trade directly with the ETF by creating or redeeming large blocks of shares (creation units).
- In-Kind Creation/Redemption: APs typically exchange a basket of underlying securities for ETF shares (creation) or ETF shares for underlying securities (redemption). This process allows the ETF to transfer appreciated securities to APs without selling them, thus avoiding the realization of capital gains.
- This "in-kind" mechanism significantly reduces the need for the ETF to sell holdings to manage cash flows, thereby minimizing capital gains distributions.

Quantifying the Difference: Data and Statistics

The transcript highlights a substantial difference in capital gains distributions:

US Equity ETFs (2024 data): Only 7% had a capital gains distribution over 0%.
US Equity Mutual Funds: A staggering 78% had capital gains distributions over 0%.

This data underscores the "pretty substantial" difference in tax efficiency.

The Importance of Controlling Tax Timing

While ETF investors will eventually pay taxes upon selling their shares, the ability to control when that tax bill arrives is crucial for long-term wealth accumulation.

Tax Drag: When a fund distributes capital gains, investors must pay taxes on those gains in the year they are received. This reduces the amount of money available for reinvestment and compounding.
Compounding Advantage: By deferring capital gains taxes until sale, ETFs allow investors' money to compound for longer periods. Brian Armor states, "you want that money compounding as long as you can before you actually pay the tax bill." Even a small return difference can become "meaningful" over long time horizons.

Beyond Tax Drag: Cash Drag

ETFs also mitigate "cash drag," the drag on performance caused by a fund holding excess cash.

Mutual Funds: Must hold cash to meet potential redemptions without disrupting their investment strategy.
ETFs: Due to the in-kind creation/redemption process and secondary market trading, ETFs can operate with minimal cash holdings, allowing them to be "nearly 100% all in on their portfolio."

Strategy Matters: Sharpening or Dulling the ETF Edge

The tax efficiency advantage of ETFs can be influenced by their underlying investment strategy.

Active ETFs vs. Active Mutual Funds: Active ETFs have shown a significant advantage. While passive ETFs (like cap-weighted index funds) inherently have low turnover and thus limited capital gains distributions, active ETFs, which trade more frequently, benefit more from the ETF structure compared to their active mutual fund counterparts.
Momentum Strategies Example: A comparison of two similar momentum strategies from Fidelity, one in ETF format and one in mutual fund format, revealed that the ETF distributed no capital gains in two out of three years examined, while the mutual fund distributed 2-3% annually.

International Stocks and Tax Complexities

Certain international markets present unique tax challenges for ETFs:

Countries with No In-Kind Tax Advantage: Countries like China, India, Brazil, and South Korea treat in-kind redemptions as taxable events, negating some of the ETF's tax efficiency benefits.
Derivatives and Currency Hedging: Instruments like currency hedges, especially in currency-hedged ETFs, cannot be processed through in-kind redemptions. Gains from these derivatives are cash-based and realized, leading to capital gains distributions. For example, during a period of significant dollar appreciation against the yen, dollar-hedged ETFs gained substantially from currency hedging alone, resulting in taxable gains.

Taxable Bond ETFs: A Caveat

While ETFs generally excel in tax efficiency, this advantage is less pronounced for certain types of bonds:

Income vs. Appreciation: For bonds where income is the primary driver (e.g., high-yield or short-term bonds), the tax treatment of income is not altered by the ETF structure. Therefore, there's little tax efficiency advantage over mutual funds.
Longer Duration Bonds: ETFs still offer a benefit for longer-duration bonds where capital appreciation occurs, as the ETF structure helps defer taxes on those gains.

Other Investments Lacking Tax Efficiency

Beyond taxable bond ETFs, other investment types that don't lend themselves to in-kind transfers with APs also miss out on the tax efficiency edge:

Various Derivatives: Certain options contracts, futures, and swaps.
Currency Hedging: As previously mentioned.
High Turnover Strategies: Any strategy involving frequent buying and selling of assets that cannot be handled via in-kind transfers will generate taxable gains.

The Impact of Outflows on Mutual Funds

Investor outflows from mutual funds can exacerbate tax liabilities for remaining shareholders.

Forced Selling: When investors redeem shares, mutual fund managers may be forced to sell holdings to generate cash, leading to realized capital gains.
Estimates: Ben Johnson of Morningstar highlighted a mutual fund estimating capital gains distributions of approximately 75% for the year, largely attributed to outflows.

Active ETFs: A Growing Trend

The popularity of active ETFs is soaring, partly due to their superior tax efficiency compared to their passive peers and mutual funds.

US Equity: Aggregated data shows 78% of mutual funds distributing capital gains versus only 7% of ETFs.
International Equity: The gap is also significant, with 46% of mutual funds distributing gains compared to 6% of ETFs.
Key Consideration: Tax efficiency is a primary reason to choose an active ETF over an active mutual fund.

Portfolio Allocation: Taxable vs. Tax-Advantaged Accounts

Strategic asset location is key to maximizing tax efficiency.

Taxable Accounts: ETFs are generally the most efficient choice for taxable accounts due to their tax-efficient nature.
Tax-Advantaged Accounts (401k, IRA): For tax-advantaged accounts, the difference between holding an ETF or a mutual fund is often less significant from a tax perspective. However, bonds, with their taxable income component, can be particularly well-suited for tax-advantaged accounts, offering similar performance and tax efficiency regardless of whether they are held in a tax-advantaged or taxable account.

Advice for Investors

For those looking to improve their asset location:

Consider Embedded Gains: Be aware of the capital gains already embedded in existing investments. This can be a barrier to switching from mutual funds to ETFs if significant taxes would be incurred.
Asset Class Allocation: Consider investing in ETFs for taxable accounts and mutual funds or Collective Investment Trusts (CITs) for retirement accounts.
Prioritize Strategy: Above all, focus on selecting investment strategies that align with your income needs and objectives.

Conclusion: Embrace ETFs for Taxable Accounts

The overarching takeaway is to utilize ETFs, especially for new money being added to taxable accounts. Brian Armor emphasizes that if asset managers were launching new strategies today, many would opt for the ETF structure over mutual funds. ETFs are a powerful tool for cutting tax bills and enhancing long-term investment growth.
