ETFs vs Mutual Funds: Taxes, Fees and Trading

Both structures can hold stocks, bonds or other investments. Either can track an index or use active management. Holdings and strategy determine risk; the label alone does not establish whether a fund is diversified or inexpensive.

A mutual fund (opens in new tab) takes money from a lot of people and uses it to buy stocks, bonds, or both. You own a share of the fund itself, not the stocks inside it directly. Someone, a fund manager, or sometimes just a computer following an index, decides what the fund buys. How much money you make depends on how those holdings do overall, minus the fund's fees.

Mutual fund shares get one price a day, set after U.S. markets close. That price is called the NAV, short for net asset value: add up everything the fund owns and divide by the number of shares. Place an order at 2:00 p.m. and you won't know your exact price until hours later, once the NAV is set. You can't buy or sell mutual fund shares throughout the day the way you can with a stock.

Read the fund's prospectus and fee table. Compare the expense ratio, any sales load and account-level charges. Index funds and actively managed funds exist in both structures. The SEC explains these distinctions in its guide to mutual funds and ETFs (opens in new tab).

Low-cost index funds, which copy the market instead of trying to beat it, have become a common choice for long-term investors. Many 401(k) plans offer at least one. Check your plan's fund list.

An exchange-traded fund (opens in new tab), or ETF, works the same basic way as a mutual fund: it pools money and buys a basket of stocks or bonds. The difference is how you buy and sell it. An ETF trades on the stock market all day long, just like a share of a company. Buy it at 10:00 a.m., sell it at 2:00 p.m., or hold it for 30 years. Its price moves throughout the day based on what it owns and on how many people want to buy or sell it right then.

Some ETFs track an index; others are actively managed. A broad stock index ETF can hold many companies, while a sector, single-stock, leveraged or inverse product can have a very different risk profile. Check the specific product's holdings, strategy, expense ratio and trading costs.

Many ETFs use in-kind redemptions, which can reduce sales of appreciated holdings when investors exit. That can mean fewer capital-gain distributions than a comparable mutual fund in a taxable account. ETFs can still distribute taxable capital gains, dividends or interest. Selling your shares can create a gain or loss.

Cost. Compare expense ratios on similar strategies, then include trading commissions, ETF bid-ask spreads, premiums or discounts to net asset value, and any mutual fund sales or redemption fees. Lower expenses do not guarantee a better investment result.

Taxes. In-kind redemptions can make some ETFs more tax-efficient in a taxable account, but either fund can make taxable distributions. In a tax-advantaged retirement account, the fund-level tax distinction generally matters less. Fees, holdings, trading mechanics and plan availability still matter.

Trading. ETFs trade all day like stocks. Mutual funds get one price a day. If you're investing for the long run, being able to trade all day rarely matters. It does make it easier to buy or sell an ETF at an exact price, which helps if you need your money fast.

Minimums. Mutual-fund minimums vary by fund, provider, and share class; some have no minimum. An ETF purchase generally requires the price of a whole share unless your broker supports fractional purchases for that ETF. Compare the specific options your account offers before choosing.

For broad-market exposure, compare low-cost index ETFs and mutual funds alongside account type, costs, and trading needs. Registered investment-company ETFs and mutual funds operate under the Investment Company Act of 1940 and disclose their objectives, risks, and fees in a prospectus. Other exchange-traded structures, such as certain commodity products or notes, follow different rules. Registration and disclosure do not make an investment safe or prevent losses.

The case for paying more for an actively managed fund comes down to one question: can the manager beat the market consistently, after fees? Historically, most can't.

Start with the expense ratio, the annual operating cost deducted from fund assets. Compare similar holdings and strategies. The prospectus shows the specific rate; an ETF is not automatically cheaper than a mutual fund.

A no-load mutual fund has no sales load, but it can still have operating expenses or other charges. Likewise, an ETF can have trading costs even when the broker charges no commission. Read the fee table and your brokerage's charges.

How to read one cost line. A front-end sales load comes out of your money before it is invested. The SEC gives this example: you write a $10,000 check for a fund with a 5% front-end load, $500 pays the load, and $9,500 buys shares. That rate is an example, not a typical charge, and many funds have no load. The fund's fee table also leaves out the brokerage commissions you may pay to trade. See the SEC's mutual fund and ETF fees bulletin (opens in new tab). A lower cost does not mean lower risk. Any fund can lose money.

An ETF's bid-ask spread is the difference between quoted buying and selling prices. It can widen when trading is thin or markets are stressed. ETF shares can also trade above or below net asset value. These costs are separate from the annual expense ratio.

A lower fee doesn't guarantee a better result. Both ETFs and mutual funds involve risk, including the possible loss of principal. A cheap fund can still lose money, and an expensive one isn't automatically bad. The fee is one thing to weigh, not the whole decision.

When mutual fund investors cash out, the fund manager sometimes has to sell some of what the fund owns to raise the cash. Selling triggers a taxable gain. That gain gets split among everyone still holding the fund at year-end, even people who never sold anything all year. You can end up owing taxes on a sale you had nothing to do with.

In an in-kind redemption, an authorized participant receives a basket of holdings rather than cash. This can reduce gains realized by the ETF. Some redemptions use cash, and an ETF may still sell investments or distribute gains. The SEC's fund comparison guide (opens in new tab) explains why the tax advantage is typical rather than universal.

ETFs and mutual funds may distribute dividends, interest, or capital gains, depending on their holdings and structure. Tax treatment depends on the distribution and your account type. Many ETFs make fewer capital-gains distributions than comparable mutual funds, but that is not guaranteed. Income distributions can still be taxable, and selling fund shares can create a taxable gain or loss.

Inside a retirement account, this tax difference generally matters less. In a traditional IRA or 401(k), you don't owe tax until you withdraw money. In a Roth IRA, qualified withdrawals are never taxed. Since nothing inside those accounts creates an immediate tax bill, the ETF's tax advantage usually doesn't help much there.

Tax rules change, and your own tax bill depends on your income, what you own, and how long you've owned it. Talk to a qualified tax professional about your specific situation.

Income, Growth, and Speculative hold individual stocks and cash equivalents. Trend uses exchange-traded products, including possible leveraged, inverse, commodity-linked, and crypto-linked products. Trend can suffer sudden and significant losses, including from trend reversals, and some products it may hold can lose their entire value. Leveraged and inverse products can amplify losses, and all of its products carry their own expenses.

An index ETF buys every company in its index, good or bad, expensive or cheap. In Income, Growth, and Speculative, we don't do that. The Income portfolio holds dividend-paying companies chosen for their cash flow. The Growth portfolio holds companies with durable competitive advantages, real edges over competitors that should hold up over time. The Speculative portfolio holds smaller, riskier companies. Every stock we hold, we picked for a reason. That's the whole point of doing it this way.

But that focus cuts both ways. Owning fewer, hand-picked stocks means more risk sits in each one. If one holding runs into serious trouble, it hurts the whole portfolio more than it would if that stock were just one of 500 in a broad index. These portfolios can trail the overall market for a long stretch, and they can lose more in a sharp downturn if the companies we hold get hit hard. That's not a bug we're trying to fix. It's how concentrated stock-picking works: bigger swings, up and down.

A taxable account with one model portfolio pays 0.60% annually for Income, 1.00% for Trend, 1.20% for Growth, or 1.60% for Speculative. Taxable accounts with two or more model portfolios pay 1.00% on the whole account, including cash. All retirement accounts, including inherited IRAs, pay a uniform 1.00% a year regardless of model portfolio mix. Fees are billed quarterly in arrears. Individual stock holdings carry no fund expense ratios. Interactive Brokers may charge separate brokerage commissions and fees, including any applicable custody, margin, or other brokerage costs.

If what you actually want is broad exposure to hundreds of companies at the lowest possible cost, an ETF through a robo-advisor or your own brokerage account is probably the better fit. See our robo-advisor vs. fee-only adviser article for that comparison. Narstar is for people who want a person managing a model portfolio for them, with a clear fee. Three of our models hold individual companies. Trend holds exchange-traded products.

Are ETFs better than mutual funds for taxes?

Many ETFs make fewer capital-gain distributions than comparable mutual funds because they can redeem holdings in kind. That is not universal: ETFs can distribute gains, and either fund can pay taxable dividends or interest. In a tax-advantaged retirement account, this distinction generally matters less. Consult a tax professional about your situation.

Which is cheaper, ETFs or mutual funds?

Neither structure is always cheaper. Compare the specific funds' expense ratios, sales loads or other fund fees, plus brokerage charges and ETF bid-ask spreads. Compare similar strategies rather than assuming every ETF costs less than every mutual fund.

Are ETFs safer than mutual funds?

No. What's inside decides the risk, not the wrapper. A stock ETF and a stock mutual fund tracking the same index carry the same risk, and both can lose value in a downturn. Some ETFs create fewer taxable distributions in a taxable account, but that is a tax difference, not a safety difference.

Which is better inside a 401(k) or IRA?

Your employer plan determines the investments available in a 401(k). In an IRA offering both structures, compare holdings, risk, fees and trading arrangements. Fund-level tax efficiency generally matters less inside a tax-advantaged account, but cost is not the only difference.

Do ETFs pay dividends?

An ETF may distribute dividends or interest from its holdings. Whether it pays, how much and how often depend on the fund and its investments. Check its distribution policy. Payments are not guaranteed, and reinvesting a distribution does not remove investment risk.

What's a sales load, and how do I avoid one?

A sales load is a sales charge on some mutual fund share classes. It can apply when buying or selling. Read the prospectus and compare no-load alternatives with similar investments. A fee-only adviser does not earn product-sales commissions, but underlying funds and brokerages can still charge fees.
