ETF Tax Efficiency vs. Mutual Funds

Much has been written about ETF tax efficiency. In this blog post, we summarize what these tax advantages look like to a individual investor who may be considering mutual funds as an alternative.

Let’s start with the basics of capital gains taxes. Short term capital gains are taxed as ordinary income, which for individuals in higher tax brackets, is far from ideal. Below are the tax brackets for married filing jointly in 2018.

So, let’s suppose you and your spouse made $175,000 in 2018. Then, for every additional $1 of short-term capital gains, you owe 24 cents of income tax. If you are fortunate enough to be earning more, tax rates are even higher. For this reason, higher earners often use municipal bond ETFs in their taxable portfolios.

What produces short-term capital gains?

There are several ways that individual investors produce short-term capital gains with ETFs and mutual funds.

  • Buying an ETF or mutual fund and reselling it for a gain in less than a year.
  • Non-qualified dividends, often produced by fixed income mutual funds and ETFs.
  • Mutual funds that buy and sell assets in their fund to meet their stated objectives or to satisfy investor redemption*.

*This last point is where ETFs carry a significant advantage. The higher the turnover of a mutual fund’s assets, the more often short-term capital gains are passed on to the individual investor.

But, ETFs have a creation/redemption process that shields these gains from the ETF investor. While some would say it’s a tax dodge, this process has represented a significant ETF tax efficiency for over 20 years. Below is a chart that shows how often these events occurred in comparable index ETFs and index mutual funds.

Conclusions

Tax efficiency is an important aspect that individual investors should consider. ETFs generally offer better tax efficiency than comparable mutual funds. While this efficiency is important for all investors, higher wage earners can reap the greatest tax benefits of using ETFs versus mutual funds.

Commission-free Municipal Bond ETFs and a diversified portfolio

Commission-free ETFs cover a number of important asset classes, including municipal bonds. “Muni” ETFs can add an important asset class to a diversified portfolio, as returns often differ from other bond ETFs. “Muni” bond ETFs also carry the important benefit of tax-exempt interest.

Not surprisingly, discount brokers like Fidelity don’t permit their use in tax-advantaged retirement accounts, like IRAs. Since there are currently 46 municipal bond ETFs, most retirement accounts really don’t have access to the full list of commission-free ETFs advertised by discount brokers. The chart below summarizes the number of commission-free ETFs available. It includes the five discount brokers analyzed regularly by ETFMathGuy to develop optimal portfolios.

This chart shows that no single broker offers all 46 “muni” ETFs commission-free. But, Schwab and Fidelity offer the most at 12, followed by ETrade (11), Ameritrade (10) and Vanguard (1).

So, what does this mean for a diversified portfolio with commission-free ETFs? ETFMathGuy will be expanding portfolio construction to include both IRA accounts (that don’t include municipal bond ETFs) and taxable accounts that do.

Please be sure to check back at the beginning of April to see how municipal bond ETFs affect the diversified portfolios created by ETFMathGuy.
