Asset location is about deciding where to hold your investments - taxable accounts, tax-deferred accounts, or tax-exempt accounts - to minimize taxes and improve after-tax returns. By aligning investments with the tax advantages of each account type, this may improve your portfolio’s after-tax growth by an estimated 0.25% to 0.75% annually. Here's the quick breakdown:
- Taxable Accounts: Best for tax-efficient investments like municipal bonds, index funds, and low-dividend stocks.
- Tax-Deferred Accounts (401(k)s, Traditional IRAs): Often used for tax-inefficient investments like taxable bonds, REITs, and high-yield funds.
- Tax-Exempt Accounts (Roth IRAs, HSAs): Often used for high-growth investments like small-cap stocks, emerging markets, and alternative assets due to their tax-free growth.
This strategy seeks to reduce tax drag and may improve after-tax growth without increasing investment risk. Regular reviews are key to ensuring your investments remain tax-efficient as your financial situation changes.
Asset Location Strategy: Which Investments Belong in Which Account Types
How to Use Asset Location to Maximize After-Tax Returns

The 3 Main Account Types
Grasping the three main account types is essential for crafting an effective asset location strategy. The tax rules tied to each type dictate how much and when you'll pay taxes, directly influencing the after-tax performance of your investments.
Taxable Accounts
Taxable accounts, such as standard brokerage accounts, are funded with after-tax dollars - money on which you've already paid income taxes. Each year, you'll owe taxes on dividends, interest, or any capital gains realized from selling investments. However, long-term capital gains (from investments held for over a year) and qualified dividends often enjoy lower tax rates of 0%, 15%, or 20%, depending on your income level - much lower than the ordinary income tax rate, which can go up to 37%.
This annual taxation, often referred to as tax drag, can slow the compounded growth of your portfolio. That said, taxable accounts offer unmatched flexibility: there are no limits on contributions, no restrictions on withdrawals, and you can even use tax-loss harvesting to offset gains.
Tax-Deferred Accounts
Tax-deferred accounts include options like Traditional IRAs and 401(k)s. Contributions to these accounts are generally made with pre-tax dollars, which lowers your taxable income for the year. The money inside these accounts grows without being taxed annually - dividends, interest, and capital gains are all tax-sheltered as long as the funds remain in the account.
Taxes come into play later when you withdraw funds, which are taxed as ordinary income at your marginal rate. Additionally, once you reach age 73, you'll face Required Minimum Distributions (RMDs), which mandate withdrawals even if you don't need the money.
Tax-Exempt Accounts
Tax-exempt accounts, such as Roth IRAs and Health Savings Accounts (HSAs), provide some of the best tax advantages. Contributions are made with after-tax dollars, but your investments grow and can be withdrawn completely tax-free. This eliminates tax drag entirely, ensuring you won’t owe taxes on your gains, no matter how much they grow.
HSAs, often called "triple tax-free", are particularly appealing. They allow pre-tax contributions, tax-free growth, and tax-free withdrawals for qualified medical expenses. For instance, a $250,000 investment in a bond fund held in a Roth IRA instead of a taxable account over 20 years could yield nearly $290,000 more in returns after taxes.
Here’s a quick comparison of the key features across account types:
| Account Type | Contributions | Annual Tax on Earnings | Taxation at Withdrawal | Common Examples |
|---|---|---|---|---|
| Taxable | After-tax | Yes – on dividends, interest, & gains | Capital gains tax on appreciation | Brokerage accounts |
| Tax-Deferred | Pre-tax (usually) | No (Tax-sheltered growth) | Ordinary income tax | 401(k), Traditional IRA |
| Tax-Exempt | After-tax | No (Tax-free growth) | None (Tax-free) | Roth IRA, Roth 401(k), HSA |
Knowing these differences helps you align your investments with the most tax-efficient account type, as we’ll discuss further in the next section.
Which Investments Belong in Which Accounts
When it comes to investing, where you hold your assets can be just as important as what you invest in. Placing investments in the right type of account helps protect your returns from unnecessary taxes. By aligning your investments with their optimal accounts, you can reduce your lifetime tax burden while maintaining your desired asset allocation. Matt Bullard, Regional Vice President for Managed Solutions at Fidelity, explains it well:
"If the same set of blocks is arranged in a more efficient way, you can often build the tower higher".
This strategy may improve your after-tax returns by an estimated 0.25% to 0.75% annually [2, 9]. The secret lies in understanding which investments generate taxable income and choosing the right account to minimize those taxes. Let’s dive into which investments work best for taxable, tax-deferred, and tax-exempt accounts.
Best Investments for Taxable Accounts
Taxable accounts are ideal for investments that either produce little taxable income or qualify for favorable tax treatment. Here are some common options:
- Municipal Bonds: Their interest is exempt from federal income tax, and often from state tax if issued in your state [11, 10].
- Index Funds and ETFs: These are tax-efficient due to low portfolio turnover, which minimizes taxable capital gains distributions [8, 11].
- Growth Stocks with Low Dividend Yields: Returns primarily come from capital appreciation, which remains untaxed until you sell.
- International Equities: These allow you to claim a Foreign Tax Credit for taxes paid to foreign governments.
- Treasury Bonds: If you live in a high-tax state, these may be appropriate since their interest is exempt from state and local taxes.
However, some investments are less suited for taxable accounts. For example, REITs often pay high dividends taxed as ordinary income, and target-date funds may trigger taxable events through internal rebalancing [11, 12].
Best Investments for Tax-Deferred Accounts
Tax-deferred accounts, like traditional IRAs or 401(k)s, are designed to shelter investments that generate significant taxable income. Here’s what works best:
- Taxable Bonds: Their interest, taxed at rates up to 37%, can grow without the drag of annual taxes.
- REITs: These high-dividend-paying investments are better suited for accounts that defer taxes.
- High-Yield (Junk) Bonds: Their substantial interest income is best kept in tax-deferred accounts to avoid tax drag.
- Actively Managed Funds with High Turnover: Frequent capital gains distributions make these funds a good fit for tax-deferred accounts.
If you anticipate required minimum distributions (RMDs) exceeding your spending needs, placing lower-growth investments, like bonds, in these accounts may help slow account growth and manage future tax liabilities.
Best Investments for Tax-Exempt Accounts
Tax-exempt accounts, such as Roth IRAs and HSAs, offer tax-free growth. To take advantage of this, investors often prioritize investments with higher growth potential. As Morningstar puts it:
"You want your largest gains to occur in the account that will not be taxed in the future".
Ideal candidates include:
- Domestic Small-Cap, Mid-Cap, and Emerging Market Stocks: These have strong growth potential and benefit from tax-free capital gains.
- Alternative Investments: Commodities or high-yield debt that might trigger frequent taxable events elsewhere work well here.
While bonds typically offer lower growth, if your tax-deferred accounts are already full, holding bonds in a Roth is still better than placing them in a taxable account. This ensures even modest returns grow tax-free.
Asset Location by Investment Type
The tax characteristics of each asset class play a big role in determining where they should be placed to maximize returns. Let’s dive into how this works for specific types of investments.
Bonds and Fixed Income
Bonds produce regular interest income, which is taxed at ordinary income rates - up to 37% for high earners. This creates a yearly tax burden that can eat into your returns. The best way to avoid this is by keeping taxable bonds in tax-deferred accounts like Traditional IRAs or 401(k)s. These accounts allow the interest to grow without being taxed annually, letting your full pretax return compound over time. High-yield bonds, which generate even more taxable income, are especially suited for these accounts.
Municipal bonds are a different story. Since their interest is exempt from federal taxes - and often state taxes if issued in your state - they’re a great fit for taxable brokerage accounts. In fact, research indicates that nearly 90% of the tax-saving benefits from asset location for high-income retirees come from two strategies: holding municipal bonds in taxable accounts and using passive stock funds in taxable accounts.
For example, a Fidelity case study found that a 40-year-old in the 35.8% tax bracket could see nearly $290,000 more in after-tax returns over 20 years by placing a taxable bond fund in a Roth IRA.
Stocks and Equities
Stocks offer more flexibility when it comes to taxes, thanks to the way dividends and capital gains are taxed. Broad-market index funds and ETFs, which typically have low turnover, are commonly used in taxable accounts. These investments generate minimal capital gains distributions, allowing you to benefit from the lower long-term capital gains tax rates of 0%, 15%, or 23.8%.
For stocks with high growth potential - like small-cap, mid-cap, or emerging market equities - a Roth IRA is ideal. These accounts allow tax-free compounding and withdrawals, meaning you won’t pay taxes on gains in these accounts.
On the other hand, high-turnover active funds often distribute short-term capital gains that are taxed at higher ordinary income rates. These are better placed in tax-deferred accounts. Non-dividend-paying stocks, such as Berkshire Hathaway, are another good option for taxable accounts since taxes are only triggered when you sell.
REITs and Tax-Inefficient Assets
Real Estate Investment Trusts (REITs) are required to distribute at least 90% of their taxable income each year, which limits their ability to defer taxes. Most of these dividends are taxed as ordinary income, meaning they could be hit with rates as high as 37%.
To minimize this tax burden, REITs are best held in tax-deferred or tax-exempt accounts. Holding them in taxable accounts can lead to a significant tax drag, as the annual taxes on their high yields reduce the amount available for compounding. Jim Dahle, founder of The White Coat Investor, notes:
"Most of the return from REITs also gets taxed at ordinary income tax rates, although it may qualify for the 199A deduction".
Under current tax laws, 20% of REIT income may qualify as business income under Section 199A, leaving only 80% subject to taxes. However, even with this deduction, REITs are less tax-efficient compared to other equity investments. Placing them strategically in the right accounts could improve after-tax returns by an estimated 0.25% to 0.75% annually.
| Asset Type | Primary Income Source | Tax Treatment | Ideal Account Location |
|---|---|---|---|
| Taxable Bonds | Interest | Ordinary Income (up to 37%) | Tax-Deferred (IRA/401k) |
| Municipal Bonds | Interest | Federal Tax-Exempt | Taxable Brokerage |
| Index Funds/ETFs | Long-term Capital Gains | Preferential Rates (0%–23.8%) | Taxable |
| REITs | Dividends (90%+ of income) | Ordinary Income (up to 37%) | Tax-Deferred / Tax-Exempt |
| Active Funds | Short-term Capital Gains | Ordinary Income (up to 37%) | Tax-Deferred / Tax-Exempt |
How Mezzi Helps Optimize Asset Location
Managing asset location across multiple accounts can feel like solving a complex puzzle. Mezzi's AI platform simplifies the process, offering tools to fine-tune your strategy and improve efficiency. Here's how Mezzi can help with your approach to asset location.
AI-Powered Tax Optimization
Taxes can quietly erode your investment returns, but Mezzi's AI is designed to catch these inefficiencies. It reviews your portfolio to identify assets creating tax drag and identify tax-loss harvesting opportunities and recommends adjustments. For example, high-growth investments, like stocks, are flagged for tax-exempt Roth accounts where they can grow without tax interference. Meanwhile, tax-inefficient assets - such as REITs, high-yield bonds, or actively managed funds - are better suited for tax-deferred accounts where their ordinary income won't hurt as much.
The platform also detects wash sales across all accounts, an often-overlooked tax rule that can lead to disallowed losses. Research suggests that optimizing asset location could boost annual returns by as much as 0.75%. On a $1 million portfolio, this strategy could add an estimated $112,000 to your retirement savings over time. Those numbers make a compelling case for tackling tax inefficiencies head-on.
Complete Account Aggregation
To optimize asset location, you need to see the full picture of your finances. Mezzi pulls together data from all your accounts - 401(k)s, IRAs, taxable brokerage accounts - into one cohesive view. This unified perspective is essential because understanding the interplay between accounts is key to making smart placement decisions.
With this aggregated data, Mezzi's AI evaluates your portfolio as a whole and suggests targeted adjustments. For instance, it might recommend moving REITs from a taxable account to a Traditional IRA or placing municipal bonds in a taxable brokerage account to leverage their tax-free benefits. By looking at the bigger picture, Mezzi ensures every piece of your financial puzzle fits perfectly.
X-Ray Feature for Hidden Exposures
Sometimes, the biggest inefficiencies are the ones you don’t see. Mezzi's X-Ray feature dives deep into your portfolio, uncovering duplicate stock exposures or hidden tax drags from actively managed mutual funds.
For example, the tool highlights high-turnover funds that distribute short-term capital gains taxed at rates as high as 37%. It also flags international equities sitting in a Roth IRA, which miss out on the foreign tax credit available in taxable accounts. By identifying these overlooked issues, Mezzi helps you make smarter moves, possibly adding 0.25% to 0.75% to your annual returns.
Common Asset Location Mistakes to Avoid
Even experienced investors can misstep when it comes to asset location. One of the biggest mistakes? Focusing too much on asset allocation while overlooking the importance of account placement. Mitch Pomerance, Vice President and Financial Consultant at Fidelity Investments, explains:
"We can't control taxes, but we can be smart about where we put our stocks and bonds in order to grow those assets with as little resistance as possible".
These common errors highlight the importance of having a thoughtful and regularly updated asset location strategy.
Ignoring Tax Implications
Placing tax-inefficient investments in taxable accounts without considering tax consequences can seriously eat into your returns over time. For instance, interest income from bonds held in taxable accounts is taxed at ordinary income rates, which can go as high as 37%. On the other hand, long-term capital gains are taxed at much lower rates of 15% to 20%.
A Vanguard study conducted in August 2024 shed light on this issue. It examined a $1 million portfolio with a 50/50 stock-to-bond ratio over 30 years. The study found that investors who prioritized placing bonds in tax-deferred accounts saved $74,000 in taxes compared to those who evenly distributed assets across all account types.
Placing Tax-Inefficient Investments in Taxable Accounts
Misplacing investments across account types is a common blunder that creates unnecessary tax drag, reducing overall returns. For example, keeping high-yield bonds, REITs, or actively managed funds with high turnover in taxable accounts leads to recurring tax bills. By applying tax optimization strategies - like proper asset location - you may improve your annual returns by 1% to 2%.
Not Reviewing Your Strategy Regularly
Asset location isn’t a "set it and forget it" approach. Regular reviews are essential to minimize tax drag and adapt to changes in your financial situation. Your income, tax bracket, and account balances evolve over time. A yearly review is usually enough to ensure your strategy stays on track with your financial goals. However, significant life events - like a job change leading to a 401(k) rollover, a major income increase, or approaching retirement - should trigger an immediate reassessment. These regular check-ins help catch inefficiencies before they turn into costly mistakes.
Conclusion: Building a Tax-Efficient Portfolio
Asset location is all about placing your investments in accounts that help you keep more of your returns after taxes. It's often called the closest thing to a "free lunch" in wealth management. Why? Because a well-planned asset location strategy may increase your after-tax returns by an estimated 0.75% to 2% annually. If you’re managing a $1 million portfolio, that could result in an estimated $10,000 to $20,000 in net returns each year.
Here’s the approach: start with your ideal asset mix, and then assign each type of investment to the account where it can be most tax-efficient. For example, tax-inefficient assets like bonds and REITs are better suited for tax-advantaged accounts. On the other hand, tax-efficient index funds tend to perform well in taxable accounts. And if you have high-growth investments, placing them in Roth IRAs lets you take full advantage of tax-free compounding.
Keep in mind, this isn’t a “set it and forget it” strategy. Changes in your income, tax laws, or even the market can impact your portfolio’s tax efficiency. That’s why regular reviews are so important to ensure your strategy stays aligned with your financial goals.
To make this process easier, tools like Mezzi's AI can help. Mezzi consolidates all your accounts - 401(k)s, IRAs, and brokerage accounts - into one place, giving you a clear, unified view. Its features, like the X-Ray tool, can identify tax-saving opportunities and highlight hidden risks. It also offers planning insights that are similar to those provided by institutional advisors, but without the typical 1% fee. With regular reviews and AI-driven insights, you can keep your portfolio evolving alongside your financial needs.
FAQs
Does asset location matter if I only use index funds?
Yes, asset location still plays a role when it comes to index funds. By holding tax-efficient index funds in taxable accounts and placing less tax-efficient investments in tax-advantaged accounts, you can reduce the tax burden on your portfolio. This approach helps maximize your after-tax returns while keeping your investments aligned with tax efficiency objectives.
How do I rebalance without creating a big tax bill?
To adjust your portfolio without facing a hefty tax bill, focus on tax-advantaged accounts like IRAs or 401(k)s. These accounts allow you to make changes without immediate tax consequences. Another option is to tweak your allocation by reinvesting dividends or steering new contributions toward underweighted assets. You might also explore tax-loss harvesting, which involves selling investments at a loss to offset gains and lower your taxable income. These approaches can help you stay on track with your investment goals while keeping taxes in check.
Which account should hold REITs and bond funds in my case?
REITs and bond funds are often better suited for tax-advantaged accounts like IRAs or 401(k)s. Why? These investments tend to generate taxable income that can add to your tax bill. By holding them in accounts with tax benefits, you can lower your tax liability and potentially improve your overall returns.
