How to Create Tax-efficient Portfolios: Top Picks for 2026
Last reviewed: June 2026
How to Build a Tax-Efficient Portfolio That Keeps More Money in Your Pocket
You look at your brokerage statement and see $5,000 of taxes taken out of gains you earned last year.
Those taxes cut into your net return and can add up to thousands of dollars over a decade.
This post shows you step-by-step how to pick accounts, choose assets, and use strategies that lower the tax bite on your investments.

- Harvest losses each year to offset gains.
- Consider municipal bonds for high-income investors.
- Review your portfolio annually and rebalance with tax-aware trades.
Choose the Right Account Types

Start by matching each investment to the account that offers the best tax treatment.
A traditional IRA lets you deduct contributions now and defer taxes until withdrawal. That works well for assets that generate ordinary income, such as bond interest or high-yield dividend stocks.
A Roth IRA uses after-tax dollars, but qualified withdrawals are tax-free. Put assets that you expect to grow a lot, like growth stocks or equity index funds, inside a Roth.
A 401(k) or 403(b) is usually pre-tax, similar to a traditional IRA, but it often has higher contribution limits. Use it for the same high-income assets you would place in a traditional IRA.
A Health Savings Account (HSA) is triple-tax advantaged: contributions are deductible, growth is tax-free, and qualified medical withdrawals are tax-free. If you have a high-deductible health plan, load the HSA with a low-cost index fund and treat it as an extra retirement bucket.
A taxable brokerage account is where you keep everything else. Here you must manage capital gains, dividend taxes, and the net investment income tax if your income is high.
Prioritize account funding
Fund the account with the most tax benefit first. If you have both a 401(k) and a Roth IRA, max the 401(k) to get the employer match, then fund the Roth up to the annual limit.
Keep a record of basis
When you move assets between accounts, the cost basis carries over. Keep a spreadsheet or use your broker’s cost-basis tracker to avoid surprise gains when you later sell.
Pick Low-Turnover Funds
Every time a fund sells a security, it creates a capital-gain distribution that the fund passes to you. High-turnover funds can generate large taxable events even if you never sell a share.
Index funds and ETFs that track broad markets typically turn over less than 5 percent per year. That means most of the gains stay inside the fund and are only taxed when you sell your shares.
Actively managed funds often turn over 50 percent or more. If you like active management, choose funds that use a tax-managed strategy, which tries to offset gains with losses inside the fund.
Example cost comparison
A 0.04 percent expense ratio index fund that turns over 3 percent will usually produce a capital-gain distribution of less than $10 on a $10,000 balance.
A 0.80 percent active fund that turns over 70 percent could generate $150 of capital gains on the same balance. The tax hit can wipe out the performance edge the manager claims.
Use Dividend Strategies Wisely
Qualified dividends are taxed at the long-term capital-gain rate, which is lower than ordinary income for most filers. However, they are still taxable in a taxable account.
Place high-dividend stocks or dividend-focused ETFs inside a Roth or traditional IRA. Inside those accounts the dividend tax is either deferred or eliminated.
If you prefer to hold dividend stocks in a taxable account, choose those that pay qualified dividends rather than ordinary dividends. Look for the “qualified dividend” label on the broker’s dividend detail page.
Dividend timing
If you receive a dividend in December, you have 30 days to sell the stock and avoid the dividend for tax purposes. This is called a “dividend capture” strategy, but it often triggers a wash-sale rule that disallows the loss. Use it only if you understand the rule.
Harvest Losses Regularly
Tax-loss harvesting means selling securities that are below your purchase price to realize a loss. That loss can offset capital gains dollar for dollar and up to $3,000 of ordinary income each year.
If your losses exceed $3,000, you can carry the excess forward to future years.
How to avoid the wash-sale rule
The wash-sale rule disallows a loss if you buy a “substantially identical” security within 30 days before or after the sale. To stay clear, replace the sold security with an ETF that tracks a broader index.
For example, sell a losing XYZ Corp stock and buy an S&P 500 ETF. The market exposure stays similar, but the security is not “substantially identical.”
Frequency
Many investors run a loss-harvest check at the end of each quarter. That balances the effort with the tax benefit.
Add Municipal Bonds for High-Income Earners
Interest from municipal bonds is generally exempt from federal income tax and, if the bond is issued in your home state, may be exempt from state tax as well.
For investors in the 35 percent or higher tax bracket, the after-tax yield of a 3 percent municipal bond can exceed the after-tax yield of a 4 percent taxable bond.
Where to buy
You can purchase municipal bond ETFs, which offer diversification and liquidity, or buy individual bonds through a broker. ETFs have lower minimums and easier rebalancing.
Risks
Municipal bonds are not free of risk. Credit quality varies, and interest rates still affect price. Stick to bonds rated A or higher unless you have a specific reason to venture into lower-rated issues.
Rebalance with Tax-Aware Trades
Portfolios drift from their target allocation as some assets grow faster than others. Rebalancing restores the intended risk profile, but each trade can trigger a taxable event in a taxable account.
Use new contributions
Instead of selling an overweight position, direct new cash into the underweight asset. This adds money where it is needed without creating a gain.
Harvest gains strategically
If you must sell a winner to rebalance, consider doing it in a year when you have enough losses to offset the gain. That keeps the net tax bill low.
Automatic rebalancing
Some robo-advisors offer tax-aware automatic rebalancing. They use loss-harvesting and careful trade sequencing to keep taxes low. Evaluate the fee versus the tax savings before signing up.
Consider State Tax Implications
State income tax rates differ widely. Some states tax capital gains at the same rate as ordinary income, while others have lower rates or no tax at all.
If you live in a state with no capital-gain tax, you may tolerate more taxable turnover in a taxable account. Conversely, in high-tax states, you should be stricter about turnover and dividend exposure.
Verify with your state department
Check your state’s department of revenue website for the latest capital-gain tax rules. Rules can change year to year, and some states offer exemptions for long-term gains on certain assets.
Use a Tax-Efficient Withdrawal Sequence
When you retire, the order in which you draw down accounts affects your tax bill.
First, tap taxable accounts to let the tax-advantaged accounts keep growing.
Second, withdraw from traditional IRAs or 401(k)s up to the point where you stay in a lower tax bracket.
Finally, tap Roth accounts, which are tax-free, once you have exhausted the other sources.
Example timeline
A 65-year-old couple with $500,000 in a taxable brokerage, $300,000 in a traditional 401(k), and $200,000 in a Roth IRA could withdraw $30,000 from the taxable account in year one, $20,000 from the 401(k) in year two, and so on, keeping their combined taxable income under $100,000 each year.
Automate the Process
Technology can help you stay tax-efficient without daily manual work.
- Set up automatic contributions to your Roth IRA and HSA each payday.
- Use your broker’s “tax-loss harvest” feature if available.
- Enable dividend reinvestment in tax-advantaged accounts only.
- Schedule an annual reminder to review your asset location and rebalance.
Tools to consider
Many major brokerages now offer a “tax-center” dashboard that shows expected tax liability for the year. Some fintech platforms integrate with your bank to move cash into the right accounts automatically.
Frequently Asked Questions
Can I hold a taxable bond fund inside a Roth IRA?
Yes. A Roth IRA shields all future interest, whether from corporate bonds, municipal bonds, or bond funds. The interest grows tax-free and qualified withdrawals are tax-free.
How often should I harvest losses?
Most investors run a loss-harvest check at the end of each quarter. If you have a large, volatile portfolio, a monthly review may capture more opportunities.
Are ETFs always more tax-efficient than mutual funds?
Generally, ETFs use an “in-kind” creation process that avoids capital-gain distributions. Mutual funds can be tax-efficient if they employ a tax-managed strategy, but most index mutual funds still generate more gains than comparable ETFs.
What if I’m in a state that taxes capital gains at a higher rate than ordinary income?
Few states do that, but if yours does, treat capital gains like ordinary income for state tax planning. Prioritize holding high-gain assets in tax-advantaged accounts to reduce the state tax bite.
Should I use a 529 plan for investment growth?
A 529 plan is designed for education expenses and offers tax-free growth when used for qualified costs. If you have no education funding need, a Roth IRA or taxable index fund usually provides more flexibility.
Is tax-loss harvesting worth the effort for a small account?
If your account is under $10,000, the potential loss may be modest and the transaction costs could outweigh the benefit. Focus on asset location and low-turnover funds first, then add loss harvesting as the account grows.
