Exchange-traded funds are becoming a more common option in 401(k)s and similar workplace retirement plans, according to The Wall Street Journal. That may appeal to many investors, but it does highlight a key issue: how to choose between taxable and tax-favored accounts.
Many investors are wise to purchase ETFs in taxable accounts, rather than 401(k)s, since ETFs don’t tend to produce large annual tax bills. That way, a tax-sheltered 401(k) can be reserved for investments that would trigger big annual taxes if purchased in taxable accounts, such as mutual funds that pay lots of interest or make big annual capital gains distributions.
ETFs are like mutual funds traded as stocks. They appeal to many active traders because they can be bought and sold as prices change throughout the trading day, while mutual funds are traded only at the end-of-day price. But this feature is wasted on investors who hold ETFs in 401(k)s and similar plans, because most plans do not permit day trading.
That leaves two other ETF benefits: low costs and tax efficiency.
It’s in the area of tax efficiency that the issue becomes trickier. Because they are structured differently from mutual funds, ETFs generally produce smaller capital gains distributions, which are annual payments to shareholders of net profits on securities sold by fund managers during the year.
In a taxable account, distributions are taxed in the year they are received, even if they are reinvested. In a 401(k), distributions are not taxed until money is withdrawn. But since ETF distributions are small, this isn’t a serious concern. So there’s not much benefit in using a 401(k) for an ETF.
