Taxes are one of the biggest drags on investment income, and most retirement plan participants have no idea how much they're losing. Research from Morningstar found that the average equity mutual fund loses approximately 1.5% of returns to taxes annually, a gap that compounds over decades into tens of thousands of dollars in reduced retirement savings. As a plan sponsor, the investment decisions you make on behalf of your participants (and the education you provide about tax efficient investing strategies) directly affect how much of their hard-earned money actually works for them.
PointOak Retirement Advisors helps plan sponsors build tax efficient investments into their retirement plan lineup and educate employees on the tax considerations that matter most for long-term wealth.
Highlights:
- Build tax efficient plan investment menus
- Reduce participant tax burden over time
- Educate employees on smart tax strategies
Why Tax Efficiency Matters for Your Retirement Plan
You already know that investment returns matter. But after tax returns are what your employees actually take home, and the difference can be significant. Capital gains taxes, income taxes on dividends, and capital gains distributions from mutual funds all chip away at participant balances year after year.
Consider the tax implications of different investment types within your plan. Actively managed stock funds with high turnover generate more taxable events than index funds or exchange traded funds. Bond funds producing ordinary income get taxed at your ordinary income tax rate, which is typically higher than the long term capital gains rate. Even within tax advantaged accounts like a 401 k, the choices you make about plan design, investment menu construction, and participant education shape how effectively your employees can manage their tax liability across all their retirement accounts.
That's where our investment analysis process helps. We evaluate over $120 billion in retirement plan assets quarterly, and tax efficiency is a key factor in how we assess each fund in your lineup.
Understanding Tax Efficient Investing: What Plan Sponsors Need to Know
Tax efficient investing is the practice of structuring investment decisions to minimize the tax bill on investment income while maximizing after tax returns. For plan sponsors, this means building an investment menu that gives participants the tools they need to manage their tax burden across taxable accounts, tax deferred accounts, and tax advantaged accounts.
How Different Accounts Are Taxed
Your employees likely hold investments across multiple account types, and each carries different tax treatment:
Tax deferred accounts (traditional 401 k, traditional IRA contributions) allow participants to reduce their taxable income today. Contributions go in on a pre-tax or tax deferred basis, and capital gains, dividends, and interest grow without triggering an annual tax bill. Participants pay federal income tax and state income taxes when they take withdrawals, typically at their ordinary income tax rate in retirement.
Tax free accounts (Roth 401 k, Roth IRA) are funded with after tax dollars. There's no upfront tax deduction, but qualified withdrawals are tax free, including all investment growth. For participants who expect to be in a higher bracket later, this can provide significant tax benefits over time.
Taxable accounts (brokerage accounts) don't carry the same tax advantages. Participants pay capital gains taxes when they sell investments at a profit, and investment income like dividends is taxed annually. Short-term gains (on assets held less than a year) are taxed at the ordinary income tax rate, while long term capital gains enjoy a lower capital gains tax rate. The long term capital gains tax rate ranges from 0% to 20% depending on taxable income, making holding period a critical factor. When participants sell investments, the difference between the sale price and the fair market value at the time of acquisition determines the taxable gain.
Health savings accounts offer a triple tax advantage: contributions reduce taxable income, growth is tax free, and withdrawals for qualified medical expenses aren't taxed. These are often overlooked as part of a broader financial strategy. Similarly, 529 plans provide tax free growth when used for qualified education expenses, giving employees another tool for managing their overall tax burden.
Asset Location
One of the most impactful tax efficient investing strategies is asset location, which involves placing investments in the account type where they'll receive the most favorable tax treatment. For example, placing tax inefficient investments (like bond funds and real estate investment trusts that generate ordinary income) inside tax deferred accounts, while keeping tax efficient investments (like index funds and exchange traded funds with low turnover) in taxable accounts. Research from Vanguard estimates that strategic asset location can add between 0.05% and 0.30% in additional after tax returns annually, a meaningful boost when compounded over a full career.
Key Tax Efficient Investing Strategies for Retirement Plan Participants
Tax Loss Harvesting
Tax loss harvesting allows investors to sell investments that have declined in value to offset capital gains from winning positions. This reduces the overall tax bill on investment income in taxable accounts. If losses exceed gains, participants can use up to $3,000 as a tax deduction against ordinary income, with remaining losses carried forward to future years. While this strategy applies primarily to taxable accounts rather than retirement accounts, educating employees on the concept helps them think holistically about their investment strategy.
Choosing Tax Managed Funds and Index Funds
The investment menu you build matters. Tax managed mutual funds and tax managed funds are designed specifically to minimize capital gains distributions and taxable events. Similarly, index funds and exchange traded funds tend to generate fewer capital gains distributions than actively managed stock funds because of lower portfolio turnover. Schwab research found that in 2022, 76% of U.S. equity mutual funds paid capital gains distributions compared to only 4% of U.S. equity ETFs, a dramatic difference in tax efficiency.
Municipal Bonds and Municipal Bond Funds
For participants with significant assets in taxable accounts, municipal bonds and municipal bond funds offer investment income that is generally exempt from federal income tax. Some may also be exempt from state and local taxes, depending on the bond issuer and the participant's state of residence. However, participants should be aware that certain municipal bonds may trigger the federal alternative minimum tax. Consulting a qualified tax professional before making these investment decisions is always a wise move.
Maximizing Tax Advantaged Account Contributions
The simplest tax efficient investing strategy is often the most powerful: encouraging employees to maximize contributions to their 401 k and other tax advantaged accounts. For 2026, the 401 k contribution limit is $24,500, with additional catch-up contributions available for employees age 50 and older. Every dollar contributed to a traditional 401 k reduces taxable income dollar-for-dollar. Our education and communications programs help participants understand how after tax contributions, Roth 401 k options, and contribution strategies work together to lower their lifetime tax burden.

Frequently Asked Questions
Tax deferred accounts (like a traditional 401 k) let participants reduce their taxable income now and pay federal income tax and state income taxes on withdrawals in retirement. Tax free accounts (like a Roth 401 k) are funded with after tax dollars, but qualified withdrawals, including all growth, come out tax free. The right choice depends on whether a participant expects their ordinary income tax rate to be higher now or in retirement.
Exchange traded funds generally produce fewer capital gains distributions than actively managed mutual funds due to their structure and lower turnover. This means participants in taxable accounts face a smaller annual tax bill. Within a 401 k, the distinction matters less since the account is tax deferred, but ETF-style index funds still benefit from lower expense ratios.
Yes. Providing both options gives employees flexibility to manage their tax burden based on their current federal tax bracket and expectations for retirement. Younger employees in lower brackets may benefit from Roth 401 k contributions (paying taxes on after tax dollars now at a lower rate), while higher earners may prefer the immediate tax deduction of traditional contributions.
Tax loss harvesting involves selling investments at a loss to offset capital gains and reduce your tax bill. This strategy applies primarily to taxable accounts, not to tax deferred or tax free retirement accounts where gains aren't taxed annually. However, participants with both retirement accounts and brokerage accounts should understand how to coordinate strategies across account types.
Municipal bonds produce investment income that is generally exempt from federal income tax, and sometimes from state and local taxes as well. Municipal bond funds offer diversified exposure to these fixed income securities. They're most beneficial for participants in higher tax brackets who hold investments in taxable accounts. Participants should consult an independent tax advisor or qualified tax professional about potential federal alternative minimum tax implications.
Absolutely. Future tax law changes can alter capital gains tax rates, income tax brackets, contribution limits, and the tax treatment of various account types. That's why ongoing monitoring matters. PointOak provides regular updates on tax laws and their implications for retirement plan investment decisions, so you're never caught off guard.
