Asset Location for Each IRA Account Type
Most investors focus on asset allocation—deciding what percentage of their portfolio should be in stocks versus bonds, domestic versus international, growth versus value. But there's another dimension of portfolio construction that can add significant value: asset location. Asset location is the strategy of deliberately placing specific types of investments in specific account types to maximize after-tax returns. Put the right assets in the right accounts, and you could boost your lifetime wealth by tens of thousands of dollars without taking any additional risk or making any different investment choices.
The key insight behind asset location is that different account types receive different tax treatment, and different investments generate different types of returns. Traditional IRAs are taxed at ordinary income rates on withdrawal, Roth IRAs offer completely tax-free growth, and taxable brokerage accounts have preferential treatment for long-term capital gains and qualified dividends. Meanwhile, some investments generate mostly capital gains (which can be tax-efficient), others throw off lots of taxable income (dividends, interest), and still others have high expected growth rates. By matching tax-inefficient investments with tax-advantaged accounts, you minimize the tax drag on your portfolio.
This comprehensive guide explores asset location strategies for IRAs and other account types. We'll explain the tax characteristics of each account type, the tax profiles of different asset classes, the principles of optimal asset location, specific recommendations for where to hold stocks, bonds, REITs, and other investments, how to implement asset location in your portfolio, and common mistakes to avoid. Whether you're just starting to build wealth across multiple accounts or optimizing a substantial portfolio, understanding asset location will help you keep more of what you earn.
Understanding the Three Account Types
Before we can discuss asset location, we need to understand how each account type is taxed.
Traditional IRAs and 401(k)s: Tax-Deferred
Tax treatment:
- Contributions may be tax-deductible (reducing current taxable income)
- Investments grow tax-deferred—no taxes on dividends, interest, or capital gains while inside the account
- Withdrawals in retirement are taxed as ordinary income at your marginal rate
- Required Minimum Distributions (RMDs) begin at age 73+
Key insight: Everything that comes out is taxed at ordinary income rates (up to 37% federal), regardless of how the money was earned inside the account. Whether you held dividend stocks, bonds, or growth stocks, withdrawals are all taxed the same.
This means traditional IRAs don't preserve the preferential tax treatment of long-term capital gains or qualified dividends. A stock held for 30 years with massive appreciation is taxed at ordinary income rates when you withdraw funds, not the lower capital gains rates you'd get in a taxable account.
Roth IRAs and Roth 401(k)s: Tax-Free
Tax treatment:
- Contributions are made with after-tax dollars (no deduction)
- Investments grow completely tax-free
- Qualified withdrawals in retirement are completely tax-free
- No RMDs during your lifetime (Roth IRAs only; Roth 401(k)s have RMDs unless rolled to Roth IRA)
Key insight: Roth accounts offer complete tax exemption on growth. This makes them ideal for investments with the highest expected returns, since all that growth escapes taxation forever. A stock that appreciates 1,000% over your lifetime generates zero tax in a Roth IRA.
Taxable Brokerage Accounts: Currently Taxable
Tax treatment:
- No deduction for contributions
- Dividends and interest are taxed annually when received
- Capital gains are taxed only when investments are sold (realized)
- Long-term capital gains (assets held over 1 year) are taxed at preferential rates: 0%, 15%, or 20% depending on income
- Qualified dividends receive the same preferential rates as long-term capital gains
- No withdrawal restrictions—access your money anytime
- Step-up in basis at death (heirs inherit assets at current market value, erasing capital gains)
Key insight: Taxable accounts impose annual taxes on income but offer preferential rates on long-term gains and qualified dividends. They also offer unique benefits like tax-loss harvesting and step-up in basis. Some investments are naturally tax-efficient in taxable accounts despite being currently taxable.
Tax Characteristics of Different Asset Classes
Different investments generate returns in different ways, with varying tax implications.
Stocks (Individual Stocks and Stock Funds)
Return sources:
- Capital appreciation (price increases)
- Dividends
Tax characteristics:
- Capital gains are deferred until you sell (in taxable accounts)
- Long-term capital gains taxed at 0-20% (preferential rates)
- Qualified dividends taxed at 0-20% (preferential rates)
- Low-dividend growth stocks are highly tax-efficient in taxable accounts
- High-dividend stocks generate more annual taxable income
Bonds (Government, Corporate, Municipal)
Return sources:
- Interest payments
- Small capital appreciation/depreciation from price changes
Tax characteristics:
- Bond interest taxed as ordinary income (up to 37%)
- No preferential rates—full taxation annually
- Exception: Municipal bonds generate tax-exempt interest
- Highly tax-inefficient in taxable accounts (except munis)
Real Estate Investment Trusts (REITs)
Return sources:
- Dividends (REITs must distribute 90% of income)
- Capital appreciation
Tax characteristics:
- REIT dividends are mostly non-qualified, taxed as ordinary income
- Very tax-inefficient—high yield taxed at highest rates
- Excellent candidate for tax-advantaged accounts
International Stocks
Return sources:
- Capital appreciation
- Dividends
Tax characteristics:
- Similar to domestic stocks
- Foreign taxes may be withheld on dividends
- Foreign tax credit available in taxable accounts (can offset U.S. taxes)
- Foreign tax credit NOT available in IRAs
- This creates a tax advantage for holding international stocks in taxable accounts
High-Yield Bonds and Bank Loans
Return sources:
- High interest payments
- Some capital appreciation
Tax characteristics:
- Interest taxed as ordinary income at high rates
- Extremely tax-inefficient in taxable accounts
Small-Cap and Growth Stocks
Return sources:
- Primarily capital appreciation
- Usually low or no dividends
Tax characteristics:
- Highly tax-efficient in taxable accounts (no annual tax drag)
- Taxes only when sold, at preferential long-term capital gains rates
- High expected returns make them valuable in Roth accounts too
The Principles of Optimal Asset Location
Several key principles guide optimal asset location decisions:
Principle 1: Put Tax-Inefficient Assets in Tax-Advantaged Accounts
Investments that generate lots of ordinary income (bonds, REITs, high-dividend stocks) should go in traditional or Roth IRAs where that income isn't currently taxable.
Principle 2: Put Highest Expected Return Assets in Roth Accounts
Since Roth accounts offer complete tax exemption, assets with the highest growth potential should go there. Every dollar of gain is tax-free forever.
Principle 3: Put Tax-Efficient Assets in Taxable Accounts
Investments that generate mostly long-term capital gains (low-dividend growth stocks, index funds with low turnover) work well in taxable accounts because they benefit from preferential rates and deferred taxation.
Principle 4: Consider Your Time Horizon
Assets you won't touch for decades should prioritize accounts with the best long-term tax treatment (Roth). Assets you might need sooner can go in more accessible locations.
Principle 5: Don't Let Asset Location Override Asset Allocation
Your overall asset allocation (e.g., 70% stocks, 30% bonds) matters more than asset location. Don't sacrifice your desired risk profile just for tax optimization. First determine your target allocation, then locate those assets optimally across accounts.
Principle 6: Consider Required Minimum Distributions
Traditional IRAs force RMDs at age 73+. Assets expected to be withdrawn via RMDs might be better placed there (since they'll be withdrawn anyway) rather than in Roth accounts where they could grow tax-free indefinitely.
Asset Location Recommendations by Account Type
Let's get specific about which assets belong in which accounts.
Traditional IRAs and 401(k)s: Best Holdings
Traditional accounts work best for tax-inefficient assets that generate ordinary income:
Priority holdings:
- Bonds (taxable bonds, corporate bonds, Treasury bonds): These generate interest taxed as ordinary income, making them terrible in taxable accounts but fine in traditional IRAs where income is deferred anyway
- REITs: High dividends taxed as ordinary income are perfect for tax-deferred accounts
- High-yield bonds and bank loans: Very high ordinary income makes these ideal for traditional IRAs
- Actively managed funds with high turnover: Frequent trading generates short-term capital gains (taxed as ordinary income), which are fine in traditional IRAs
- Inflation-protected securities (TIPS): Generate phantom income annually that's taxed even though you don't receive the cash, making them terrible in taxable accounts
Why these work: Traditional IRAs tax everything as ordinary income on withdrawal anyway, so you're not losing any preferential tax treatment. Meanwhile, you avoid annual taxation on the income these assets generate.
What NOT to hold:
- Growth stocks with minimal dividends (wasted in traditional IRA; better in Roth or taxable)
- Municipal bonds (already tax-exempt, so tax-deferral provides no benefit)
- International stocks (you lose the foreign tax credit)
Roth IRAs and Roth 401(k)s: Best Holdings
Roth accounts should hold assets with the highest expected returns since all growth is tax-free:
Priority holdings:
- Small-cap stocks and small-cap index funds: Historically higher returns than large-cap, all that growth becomes tax-free
- Emerging market stocks: Higher risk and higher potential returns; tax-free growth maximizes their value
- Growth stocks and growth funds: Companies reinvesting earnings for high growth; all appreciation is tax-free
- Individual stocks with highest conviction: If you believe certain stocks will dramatically outperform, put them in your Roth to exempt all gains from tax
- Alternative investments with high return potential: Private equity, venture capital, cryptocurrency (if permitted), etc.
- REITs: Yes, REITs can go here too—they're tax-inefficient AND have decent return potential, making them suitable for Roth
Why these work: Roth accounts exempt all growth from taxation. Maximize this benefit by holding assets with the highest expected appreciation.
What NOT to hold:
- Cash or money market funds (zero growth potential wastes the Roth's tax-free growth advantage)
- Low-return, stable assets (you're not maximizing the Roth benefit)
Taxable Brokerage Accounts: Best Holdings
Taxable accounts work best for tax-efficient investments that benefit from preferential rates or the step-up in basis:
Priority holdings:
- Total stock market index funds or S&P 500 index funds: Low turnover, mostly capital appreciation, qualified dividends, very tax-efficient
- International stock index funds: You can claim foreign tax credits on foreign dividends in taxable accounts (not available in IRAs)
- Individual growth stocks held long-term: Capital gains taxed at preferential rates, step-up in basis if you die holding them
- Municipal bonds: Tax-exempt interest makes them only suitable for taxable accounts (wasted in IRAs)
- Tax-managed funds: Funds specifically designed to minimize taxable distributions
- ETFs: Generally more tax-efficient than mutual funds due to their structure
- Qualified Small Business Stock: Special tax benefits only available in taxable accounts
Why these work: These assets benefit from preferential long-term capital gains rates (0-20% vs. 37% ordinary income), tax deferral on unrealized gains, ability to harvest losses, and step-up in basis for heirs.
What NOT to hold:
- Taxable bonds (interest fully taxed annually at ordinary rates)
- REITs (dividends fully taxed annually at ordinary rates)
- High-turnover actively managed funds (generate lots of taxable short-term gains)
Sample Asset Location Strategies
Let's look at specific examples showing how to implement asset location.
Example 1: Simple Portfolio
Investor: Maria, age 35
Accounts:
- Traditional 401(k): $50,000
- Roth IRA: $30,000
- Taxable brokerage: $20,000
- Total: $100,000
Desired allocation: 70% stocks, 30% bonds
Asset location strategy:
Traditional 401(k) ($50,000):
- $30,000 in bond index fund (entire bond allocation goes here first)
- $20,000 in stock index fund
Roth IRA ($30,000):
- $15,000 in small-cap stock index fund (highest expected return)
- $15,000 in emerging market stock fund (high growth potential)
Taxable brokerage ($20,000):
- $10,000 in total stock market index fund (tax-efficient)
- $10,000 in international stock index fund (to capture foreign tax credit)
Result:
- Total stocks: $70,000 (70%)
- Total bonds: $30,000 (30%)
- Target allocation achieved with tax-optimized location
Example 2: More Complex Portfolio
Investor: Robert, age 55
Accounts:
- Traditional 401(k): $400,000
- Roth IRA: $100,000
- Taxable brokerage: $200,000
- Total: $700,000
Desired allocation: 60% stocks (including 10% REITs), 40% bonds
Asset location strategy:
Traditional 401(k) ($400,000):
- $280,000 in bond funds (entire bond allocation)
- $70,000 in REIT fund (tax-inefficient)
- $50,000 in stock index funds
Roth IRA ($100,000):
- $40,000 in small-cap value stocks (high expected return)
- $40,000 in emerging markets (high growth potential)
- $20,000 in individual growth stocks (highest conviction picks)
Taxable brokerage ($200,000):
- $100,000 in total U.S. stock market index fund
- $100,000 in international stock index fund (foreign tax credit)
Result:
- Total stocks: $350,000 (50%)
- Total REITs: $70,000 (10%)
- Total bonds: $280,000 (40%)
- Tax-optimized while maintaining target allocation
Example 3: High-Income Investor
Investor: Jennifer, age 42, high earner in 35% tax bracket
Accounts:
- Traditional 401(k): $300,000
- Roth IRA: $75,000
- Taxable brokerage: $500,000
- Total: $875,000
Desired allocation: 80% stocks, 20% bonds
Asset location strategy:
Traditional 401(k) ($300,000):
- $175,000 in bond funds (entire bond allocation)
- $75,000 in REIT funds
- $50,000 in emerging market stocks
Roth IRA ($75,000):
- $50,000 in small-cap stock index
- $25,000 in technology growth stocks
Taxable brokerage ($500,000):
- $250,000 in total U.S. stock market index fund
- $150,000 in international stock index fund
- $100,000 in municipal bond fund (tax-exempt, valuable at her high bracket)
Result:
- Total stocks: $700,000 (80%)
- Total bonds: $175,000 (20%, not counting muni bonds)
- Additional municipal bonds provide tax-free income without changing stock/bond ratio for retirement planning purposes
Special Considerations
Municipal Bonds: The Exception
Municipal bonds generate tax-exempt interest, making them valuable in taxable accounts for high-income investors. However, they only make sense if:
- Your marginal tax rate is high enough (generally 24%+ bracket)
- The after-tax yield of munis exceeds taxable bonds after accounting for your tax rate
Never hold municipal bonds in IRAs—you're wasting the tax exemption since IRA withdrawals are taxed anyway (traditional) or already tax-free (Roth).
The Foreign Tax Credit
International stocks held in taxable accounts allow you to claim a foreign tax credit for taxes paid to foreign governments on dividends. This credit offsets your U.S. tax liability.
In IRAs, you can't claim this credit—the foreign taxes are just lost. This creates a small tax advantage for holding international stocks in taxable accounts rather than IRAs.
However, this advantage is relatively modest (often 1-2% of the dividend yield), so don't let it override other asset location priorities.
I-Bonds and Series EE Bonds
Savings bonds can only be held in taxable accounts (not in IRAs). Their interest is exempt from state taxes and can be exempt from federal taxes if used for qualified education expenses.
Asset Location for Bonds: The Debate
There's some debate among financial planners about bond placement:
Traditional view: Bonds are tax-inefficient, so put them in traditional IRAs.
Alternative view: Bonds have lower expected returns than stocks. Since Roth accounts are precious and limited, maybe bonds should go in traditional IRAs and Roths should be reserved exclusively for high-return assets.
Both views have merit. The traditional view optimizes current tax efficiency. The alternative view optimizes long-term growth potential. Most experts favor the traditional view, but it's worth considering your personal situation.
Practical Implementation Strategies
Start With Asset Allocation, Then Optimize Location
- Determine your target asset allocation across all accounts combined
- Calculate dollar amounts needed in each asset class
- Place tax-inefficient assets in tax-advantaged accounts first
- Place highest-expected-return assets in Roth accounts
- Place tax-efficient assets in taxable accounts
- Fill remaining space to complete your allocation
Rebalancing Across Account Types
When your portfolio drifts from target allocation, rebalance strategically:
- Rebalance within tax-advantaged accounts first (no tax consequences)
- Use new contributions to rebalance rather than selling (avoids taxes)
- If you must sell in taxable accounts, harvest losses simultaneously to offset gains
- Consider whether rebalancing is worth the tax cost, or if you can live with slight drift
Don't Let Asset Location Create Analysis Paralysis
Asset location optimization is valuable, but don't let perfect be the enemy of good:
- If you can only access certain funds in your 401(k), work with what you have
- If rebalancing to optimal location triggers large capital gains, it might not be worth it
- The benefit of asset location is real but modest—usually 0.1-0.5% annual return improvement
- Don't sacrifice your overall asset allocation just to optimize location
Common Mistakes to Avoid
Mistake 1: Holding Bonds in Roth Accounts
Roth accounts are precious—you have limited space and all growth is tax-free forever. Don't waste this on low-return bonds. Put bonds in traditional IRAs and save your Roth space for high-growth assets.
Mistake 2: Holding Municipal Bonds in IRAs
Municipal bond interest is already tax-exempt. Holding them in a traditional IRA means you'll eventually pay ordinary income taxes on that tax-exempt income (when you withdraw from the IRA). In a Roth IRA, you're wasting the account's tax-free benefit on an asset that already doesn't generate taxable income.
Mistake 3: Ignoring Foreign Tax Credit
If you hold international stocks in an IRA, you lose the ability to claim foreign tax credits. While this is a small disadvantage, it's worth considering—international stocks get a slight tax advantage in taxable accounts.
Mistake 4: Over-Optimizing at the Expense of Simplicity
Asset location optimization can become complex. If tracking assets across multiple accounts becomes overwhelming, it's okay to simplify. A simple three-fund portfolio (total U.S. stock, total international stock, total bond) held proportionally across all accounts is perfectly fine and far better than not investing at all.
Mistake 5: Triggering Large Capital Gains to Reoptimize
If you have a taxable account with large unrealized gains in tax-inefficient assets (like REITs or bonds), selling them to move to IRAs could trigger a huge tax bill. Sometimes it's better to leave your location suboptimal rather than pay the tax cost of fixing it.
Mistake 6: Forgetting About Required Minimum Distributions
If you'll face large RMDs from your traditional IRA, the asset location benefit diminishes because you'll be forced to withdraw assets regardless of tax efficiency. In this case, don't overthink location in traditional IRAs—focus on Roth and taxable optimization.
The Value of Asset Location
How much does asset location actually matter? Studies suggest proper asset location can improve after-tax returns by 0.1% to 0.5% annually, depending on your situation.
That might not sound like much, but over a 30-40 year investing career, it compounds significantly:
- 0.2% annual improvement on a $500,000 portfolio over 30 years: ~$50,000 additional wealth
- 0.4% annual improvement on a $1,000,000 portfolio over 30 years: ~$200,000+ additional wealth
This is essentially free money—you don't take any additional risk or make different investment choices. You simply place the same assets in different accounts to minimize taxes.
Conclusion
Asset location is a powerful yet often overlooked strategy for maximizing after-tax investment returns. By deliberately placing tax-inefficient investments like bonds and REITs in traditional IRAs, high-growth investments in Roth IRAs, and tax-efficient investments like stock index funds in taxable accounts, you minimize the tax drag on your overall portfolio without changing your risk profile or investment strategy.
The key principles are straightforward:
- Traditional IRAs: Tax-inefficient income generators (bonds, REITs, high-yield investments)
- Roth IRAs: Highest expected return assets (small-cap, emerging markets, growth stocks)
- Taxable accounts: Tax-efficient assets (stock index funds, especially international for foreign tax credit, municipal bonds for high earners)
Start by determining your overall asset allocation, then strategically locate those assets across account types to minimize taxes. Rebalance within tax-advantaged accounts when possible, and don't sacrifice your allocation for perfect location—your allocation matters more.
While asset location isn't as critical as factors like saving consistently, choosing low-cost index funds, or maintaining an appropriate asset allocation, it's a relatively easy way to boost returns by 0.2-0.5% annually. Over a lifetime of investing, that free lunch compounds into substantial additional wealth that stays in your pocket rather than going to taxes.
