Same Investments, Less Tax: How Asset Location Works

Where you hold your ETFs can matter almost as much as which ETFs you hold. As a general rule, tax-efficient stock ETFs suit a taxable brokerage account, income-heavy funds such as bonds suit a traditional IRA or 401(k), and the investments you expect to grow fastest suit a Roth, where the growth is never taxed.

This idea is known as asset location. It does not change what you own or how much risk you take. It simply arranges the same investments across your accounts so less of your return is lost to tax.

This guide explains how each account type is taxed, which ETFs belong where, and, with FRC’s own calculations, how much the right placement can be worth over 30 years.

How FRC’s Courses Teach Tax Placement

Tax placement is one of the topics free content handles worst. It is scattered across forum posts and short videos, often out of date, and rarely explained alongside the investments themselves.

Advanced ETF Investing covers tax placement as part of managing a complete portfolio, after ETF Investing Strategies has taught you how to set an asset allocation. Every chapter ends with a 15-question assessment with an 80% pass mark, and the next chapter only unlocks once you pass.

FRC uses AI teachers to present its video lessons in the FRC dictionary, so every lesson is delivered to the same high standard, every time, and every lesson is reviewed by qualified finance and compliance professionals before it is published. FRC does not give personal tax advice, so for your own situation, speak to a qualified tax professional.

The Three Main Account Types

The key difference is when tax bites. A taxable account taxes you along the way, a traditional account taxes you at the end and a Roth, if you follow the rules, never taxes the growth at all. FRC’s guide to Roth IRA rules explains those rules in full.

How ETFs Are Taxed in a Taxable Account

In a taxable account, you pay tax each year on the income your ETFs pay out. Qualified dividends, which most broad US stock ETFs pay, are taxed at lower capital gains rates, while bond interest and many other distributions are taxed as ordinary income.

When you sell, any profit is taxed as a capital gain. Gains on ETFs held for more than a year, and qualified dividends, are taxed at 0%, 15% or 20% depending on your income, while short-term gains, bond interest and non-qualified dividends are taxed at ordinary income rates of up to 37%.

That gap between the two sets of rates is the whole reason asset location works. Broad stock ETFs rarely distribute capital gains of their own, because their structure lets them avoid most of the selling that would trigger them.

That combination makes broad stock ETFs among the most tax-efficient investments you can hold in a taxable account. Bond funds and high-income funds are the opposite, because most of their return arrives as income that is taxed every year.

The Asset Location Principle

The idea is to place each investment where its taxes do the least damage. The table shows the general starting point most investors use.

These are guidelines, not laws. Your own tax bracket, your state and how much room you have in each account all change the best answer.

What the Right Placement Is Worth

To put a number on asset location, FRC modeled an investor with $100,000 split equally between a stock ETF and a bond ETF, held for 30 years. Half sits in a taxable account and half in a tax-advantaged account.

The assumptions are simple: stocks grow 6% a year plus a 2% qualified dividend taxed at 15%, bonds yield 4% taxed at 24% as ordinary income, traditional account withdrawals are taxed at 24%, and the taxable stock gains are taxed at 15% when sold. The figures are after all taxes, ignore rebalancing and are illustrations, not forecasts.

With a traditional IRA, putting the bonds inside it and the stocks in the taxable account was worth about $32,700 more. With a Roth, the answer flipped: putting the faster-growing stocks inside the Roth was worth about $49,200 more, because their much larger gains were never taxed.

In the Roth example, the same investments, the same risk and the same returns produced results almost $50,000 apart. Nothing changed except which account each fund sat in.

Expressed as a yearly figure, the better placement added about 0.22% a year after tax in the traditional IRA example and about 0.29% a year in the Roth example. That sits squarely within the range of roughly 0.05% to 0.75% a year that most studies of asset location report, with the size of the gain depending on your tax bracket, your mix of investments and how much room you have in each account.

What a Small Yearly Gain Adds Up To

A fraction of a percent a year sounds too small to bother with. FRC calculated what extra after-tax return is worth on $100,000 growing at 7% a year for 30 years.

At the top of the range, smart placement was worth more than $177,000, without taking on any extra risk. Even a modest 0.25% a year added over $55,000, which is many times the cost of learning how to do it properly.

A Worked Example Across Three Accounts

Imagine an investor with $100,000 spread across three accounts: $40,000 in a 401(k), $20,000 in a Roth IRA and $40,000 in a taxable brokerage account. Their target mix is 60% US stocks, 20% international stocks and 20% bonds.

The overall mix is exactly the investor’s target. Only the placement has been optimized, and each fund sits where its taxes do the least harm.

The Hidden Cost of Bonds in a Taxable Account

Bond interest is one of the most heavily taxed forms of investment income. FRC compared $100,000 in a bond fund yielding 4% a year for 30 years, held in two different ways.

Annual tax on the interest cost about $78,800 of growth over 30 years. That is why bonds are usually the first investment moved into a tax-advantaged account when space allows.

Where to Hold International ETFs

Many foreign countries withhold tax on dividends paid by their companies, and international ETFs pass that cost on to you. In a taxable account, US investors can usually claim a foreign tax credit to offset it.

Inside an IRA or 401(k), that credit is generally lost, because the account pays no US tax to offset. For that reason, many investors hold international stock ETFs in their taxable account where they can. FRC’s dictionary entry on withholding tax explains how it works.

Traditional or Roth: The Choice Behind the Placement

Whether a traditional or Roth account suits you better depends largely on your tax rate now compared with your expected rate in retirement. If you expect a lower rate later, a traditional account’s upfront deduction is usually worth more, and if you expect a higher rate, a Roth usually wins.

That choice also shapes your asset location. Because Roth growth is never taxed, the more Roth space you have, the more of your fastest-growing investments it makes sense to hold there.

The Health Savings Account

If you have a high-deductible health plan, a health savings account (HSA) can act as a fourth investment account. Contributions are tax-deductible, growth is untaxed, and withdrawals for qualified medical expenses are tax-free.

Many HSA providers let you invest the balance in ETFs or index funds. For investors who can afford to leave the money invested for years, it is often treated like a Roth for asset location purposes, holding long-term growth investments.

Rules That Catch Investors Out

The wash sale rule applies across your accounts. Selling an ETF at a loss in your taxable account and buying the same fund in your IRA within 30 days can cancel the tax benefit of the loss, and in that case the loss may be lost for good.

Traditional IRAs and 401(k)s also carry required minimum distributions, which force withdrawals from age 73 for most people today. A large traditional account full of fast-growing stocks can create large taxable withdrawals later, which is another reason many investors favor a Roth for their highest-growth holdings. Roth IRAs have no required minimum distributions during the owner’s lifetime, and since 2024 Roth 401(k)s have had none either.

Tax-loss harvesting, selling investments at a loss to offset gains, only works in a taxable account. It is one more reason to keep at least some of your stock ETFs there.

Asset Location and Rebalancing

When your funds are spread across several accounts, rebalancing becomes a little more involved. The aim is to keep your total mix on target across all accounts combined, not inside each one separately.

Rebalancing inside a 401(k) or IRA creates no tax, so many investors make all their adjustments there and leave the taxable account alone. FRC’s guide to how to rebalance an ETF portfolio explains how to do it without triggering unnecessary tax.

When Asset Location Matters Less

Asset location only matters when you have money in more than one type of account. If everything sits in a single 401(k) or a single Roth IRA, there is nothing to arrange.

It also matters less for investors who only hold broad stock ETFs, because those are already tax-efficient wherever they sit. The bigger the bond, REIT or high-income share of your portfolio, the more asset location is worth.

Common Asset Location Mistakes

The most common mistake is holding high-income funds, such as bond or covered call ETFs, in a taxable account while broad stock ETFs sit in an IRA. That is often the exact opposite of the efficient arrangement.

The second is holding municipal bonds inside an IRA, where their tax-free interest gives no benefit. The third is triggering the wash sale rule by buying in one account what you just sold at a loss in another.

The last is letting tax drive every decision. Your asset allocation, the overall mix of stocks and bonds, comes first, and asset location is a way to make that same mix more efficient, never a reason to change it. FRC’s guide to how to choose tax-efficient ETFs covers the taxable side in more detail.

Questions People Ask

What is asset location? It is the practice of deciding which investments go in which type of account, taxable, traditional or Roth, to reduce the tax you pay. It is different from asset allocation, which decides the overall mix of investments.

Should I hold ETFs in a Roth IRA or a taxable account? Both can work. Many investors put the funds they expect to grow fastest in a Roth, so their largest gains are never taxed, and keep broad, tax-efficient stock ETFs in a taxable account.

Should bonds go in an IRA? Often, yes. Bond interest is taxed as ordinary income every year in a taxable account, so bonds are usually the first investment moved into a traditional IRA or 401(k).

What are the best ETFs for a Roth IRA? FRC does not recommend specific funds. Many investors use their Roth for higher-growth investments, because a Roth’s biggest advantage is that its growth is never taxed.

Do I pay tax on ETF dividends in an IRA? No, not while the money stays inside the account. With a traditional IRA, you pay income tax when you withdraw, while qualified Roth withdrawals are tax-free.

Is it bad to hold ETFs in a taxable account? Not at all. Broad stock ETFs are among the most tax-efficient investments there are, and a taxable account gives you flexibility to access your money and to harvest losses.

Should I hold dividend ETFs in a Roth IRA? It can make sense, especially for funds that pay large or non-qualified distributions, such as covered call ETFs. Funds paying mostly qualified dividends are taxed lightly in a taxable account, so the benefit of sheltering them is smaller.

Can I hold the same ETF in more than one account? Yes. Many investors hold the same broad fund in several accounts, but be careful with the wash sale rule if you sell it at a loss in one account and buy it in another.

Should I put an S&P 500 ETF in my Roth or my taxable account? Either can work, because an S&P 500 ETF is tax-efficient. If your Roth space is limited, many investors use it for whatever they expect to grow fastest, and if bonds need a home, they usually take priority in tax-advantaged accounts.

Where should I hold international ETFs? Often in a taxable account, because the foreign tax credit that offsets withheld foreign taxes is usually only available there.

Does asset location matter? It matters most when you hold bonds, REITs or other high-income funds and have money in more than one type of account. If all your money sits in one account, or you only hold broad stock ETFs, the benefit is small.

Is it better to hold a mutual fund or an ETF in a taxable account? In most cases an ETF. Mutual funds often have to sell holdings to pay departing investors, which can trigger capital gains distributions for everyone in the fund, while ETFs can usually avoid this through in-kind creations and redemptions.

Is it safe to keep more than $500,000 in a brokerage account? SIPC protection covers up to $500,000 per customer, including up to $250,000 in cash, if a member brokerage firm fails, and accounts held in different capacities, such as an individual account and an IRA, are covered separately. SIPC does not protect against market losses, and brokerage firms must keep customer securities separate from their own assets.

How do I decide which account to fund first? That depends on employer matches, contribution limits and your tax bracket. FRC’s guide to the order to invest your money explains the usual sequence.

The Bottom Line

Asset location arranges the investments you already own so less of your return goes to tax. Tax-efficient stock ETFs usually suit a taxable account, income-heavy funds usually suit a traditional IRA or 401(k), and the fastest-growing investments usually suit a Roth.

In FRC’s Roth example, the same portfolio ended almost $50,000 apart depending only on placement. Learn to make these decisions with confidence through ETF Investing for Beginners, ETF Investing Strategies and Advanced ETF Investing, and speak to a tax professional about your own situation.
