Bond ETFs and Money Market Funds

One of our favorite WSJ writers this week provided a critical analysis of money market funds, which many individual investors use to hold their cash. In this post, we discuss the similarities and differences between money market funds and ETFs that invest in treasury bills.

The purpose of money market funds

One purpose of a money market fund in a taxable brokerage account is to provide a place for cash to stay after it is transferred in from an outside source, like a bank checking or savings account. It also serves as a holding place for securities after they are sold. But some investors are also using them as a safe haven to avoid sharp changes in the stock market. Unfortunately, these funds tend to charge relatively high fees compared to ETFs that provide a similar safe haven. According to this WSJ article, the average money market fund charges 0.51% in fees and yields 3.89%.

But you’re probably getting ripped off on your money-market funds—and it’s one of the biggest heists on Wall Street.

Jason Zweig, WSJ columnist, May 2, 2025

Brokerages also use money market funds as a “sweep” account for investors. So, investors can benefit from this feature by being able to write checks against these balances. However, the cost and convenience of assets in these funds, which often invest in short-term U.S. treasury bills, means investor returns underperform when compared to investing in an ETF with a similar level of risk.

Very low risk ETFs

Bond ETFs still have risks, depending on the type of bonds included in them. But some bond ETFs can provide investors with direct access to short-term treasury bills, which some would refer to as a good proxy for a risk-free rate. The list below shows several of these types of ETFs, along with their expense ratio and assets under management.

ETF	Ticker	Expense	Assets Under Management
iShares 0-3 Month Treasury Bond ETF	SGOV	0.09%	$45 B
SPDR Bloomberg 1-3 Month T-Bill ETF	BIL	0.14%	$47 B
iShares Short Treasury Bond ETF	SHV	0.15%	$22 B

Three large ETFs investing in short-term U.S. treasury bills

Although the expense ratios are all quite similar, it is clear that the return of SGOV is likely to be the highest. The figure below shows this is true and that all of these ETFs had a slow and steady investment return over the last three years.

Total returns for the last three years of short-term U.S. treasury bill ETFs were higher than the average money market fund. — Total returns for the last three years of short-term U.S. treasury bill ETFs

So, investors willing to take the time to invest their money market funds into one of these ETFs can often earn very close to the current U.S. treasury bills yield, which in the last year was about 4.8%. Additionally, these ETF returns may be exempt from state taxes, unlike money market funds. Investors not needing the convenience of money market funds may wish to consider these ETFs as an alternative safe haven.

Multiple Profiles added as a New Feature

Our mission is to help educate investors interested in tax-efficient investing and financial planning. Unfortunately, the complexity of producing tax-efficient retirement income makes this optimal decision-making process challenging. So, we provide online access to the algorithms from our award-winning published research. In this post, we are proud to announce a multiple profiles feature. This new feature can help individual retirees standardize and expedite tax-efficient retirement income plans. Additionally, financial planners may benefit from this time-saving feature too.

We now support multiple profiles in our web access to algorithms from our award-winning published research on tax-efficient retirement income. — The main page for interactive personal finance calculators at https://apps.etfmathguy.com

How to Enable Multiple Profiles

Our user community has sent us significant feedback about data input. Specifically, we should provide a streamlined approach in our interactive calculators: The Retirement Income Calculator and; the Pre-Retirement Savings Forecast. So, after a significant development effort, all registered users can now save multiple profiles to the Retirement Income Calculator. Please note: Free registration for these calculators is separate from the email list we use for distributing our monthly newsletter.

So, once registered, here is how you can enable these additional profiles. First, click on the green button labeled “Enable Client Feature” found in your profile at https://apps.etfmathguy.com/profile.

Once you click this button, you will see “Clients” listed as a link in the menu bar at the top of the page.

Next, clicking “Clients” in the menubar will lead users to a page where they may manage unique profiles. The example image below shows how we set up two different user profiles that are similar to hypothetical examples from our award-winning paper.

Why use this new feature?

Retaining multiple profiles for a retiree (and their spouse or domestic partner) saves significant time each year when planning for tax-efficient retirement income. Additionally, retirement income plans often consider alternative plans, based on different economic, income, and time horizon assumptions. Lastly, financial planners and retirees may simply want to save their planning assumptions for later use. With this new and free feature of multiple profiles, all users of our retirement income calculator now have these benefits available for up to two profiles. To support our professional financial advisor community and their clients, our next upgrade will include support for even more profiles.

Do you have suggestions for other features? If so, please Contact Us with your suggestions or to provide general feedback.

Always defer taxes in retirement?

Tax-deferred accounts avoid annual tax payments during our working years. Workers who defer taxes in accounts like 401(k)s accelerate growth for many years. However, distributions of retirement income from these accounts usually contribute to a retiree’s ordinary income for that year. So, these distributions are taxed much like wages are during our working years. This recent article in the WSJ highlighted that there are reasons to think more strategically about continuing to defer taxes in retirement.

“To be sure, the idea of accelerating income violates the first rule of traditional tax planning, which is to defer taxes whenever possible. But there are reasons to rethink this rule now. “
Laura Saunders, 31 January 2025, “When Paying More Tax, Not Less, Is the Smart Play“

We couldn’t agree more! In fact, we made this and other salient points in our award-winning article entitled “Seeking tax alpha in retirement income“. We supported our observations and conclusions through rigorous mathematical modeling of tax laws most relevant to retirees in the U.S.A.

In this post, we highlight this recent news article. We then provide a suggestion on how an individual or financial advisor may improve their retirement income strategy.

Time horizon

A key flaw in deferring taxes is that many retirees need to look at a longer time horizon. Currently, a 65-year-old male retiree can expect to live another 18 years. Similarly, a 65-year-old female retiree can expect to live to 21 years more. So, unless a retiree has some known terminal illness or other significant health issue reducing their life expectancy, tax-efficiency in retirement can take advantage of this time horizon.

Termed “stealth” taxes, tax-deferred account typically force retirees to begin taking requried minimum distributions (RMDs) at age 73. These distributions only grow, as a percent of a tax-deferreed account value, due to a shorter life expectancy for each year a retiree ages. Along with other factors, like the widows-penalty when a surviving spouse files their tax returns as a single, net-investment income tax, and income-related premiums for Medicare, these RMDs can be tax inefficient.

When you may not want to defer taxes

Unfortunatley, there is no single decision that a retiree can make to maximize their tax efficiency. But, for retirees with significant assets in tax-deferred accounts, the algorithms in our article “Seeking Tax Alpha in Retirement Income” are available online. We encourage you or your financial advisor to try our free online calculator. With it, you can see the amount of tax efficiency potentially available by accelerating tax-deferred distributions and avoiding RMDs.

The biggest ETF may be changing

The largest and oldest ETF is the SPDR S&P 500 ETF Trust (ticker: SPY), with $624 B in assets under management. However, two other S&P 500 ETFs are close behind. The Vanguard S&P 500 ETF (ticker: VOO) and iShares Core S&P 500 ETF (ticker: IVV) have $588 B and $582 B of assets under management. In this post, we discuss the likely change in the largest ETF, what may be contributing to it, and why it matters to investors.

The oldest ETF, SPY

The SPDR S&P 500 ETF Trust, commonly referred to as SPY, has been around the longest of any ETF. With an inception date of January 1993, SPY created an entirely new way to invest in a passive index that offered greater tax efficiency than mutual funds. As we wrote about a few years ago, the taxable gains between ETFs and mutual funds can be significant. This tax inefficiency makes no difference for Individual Retirement Accounts (IRAs). But for taxable account holders, significant tax drag is drawing investors into ETFs. Several mutual funds are converting to ETFs.

The two other S&P 500 index ETFs

ETFs from Vanguard and iShares also offer ETFs that track the S&P 500 index. This index is very popular with many investors as it diversifies across many equity sectors. But, because of its weighting by market capitalization, some companies hold more significant influence. Nevertheless, it remains a popular index for investors. And, with an expense ratio of 0.03%, these ETFs offer this exposure with very little cost. These expense ratios are in stark contrast to SPY, with its expense ratio of 0.09%. While still small, the expense ratio of SPY is 3X larger, helping VOO and IVV to grow faster than SPY.

Another driver of ETF growth

So, investors seem to be preferring lower expense ratio ETFs. VOO’s unique structure may also be contributing to its popularity. But, this benefit, which Vanguard patented, has expired in 2023. So, IVV and VOO may continue to grow at a similar rate. For individual investors, the small difference between the two ETF structures likely makes little difference in meeting their investment objectives.

Catch-up contributions to retirement plans

The IRS recently changed retirement savings plans, like 401(k) plans offered by many employers, for workers nearing retirement. Previously, workers 50 and over could make catch-up contributions. Starting in 2025, employees between 60 and 63 can increase these catch-up contributions by an additional 14%, according to this WSJ article. In this post, we discuss why many workers may want to take advantage of this new rule.

401(k) plan contributions

Employee contributions to 401(k) plans were originally established to encourage growing a nest egg for retirement. By contributing pre-tax income, workers could also reduce their current-year taxable income. For older workers who were unable to save earlier in their careers, these catch-up contributions can help retirees meet their savings goals. Also, as many workers enter their 50s, their income often peaks. So, the deferred taxes on 401(k) contributions may provide an added benefit if income is lower in retirement.

Retirement plan catch-up contributions change for 2025. — Retirement plan catch-up contributions change for 2025

Pre-tax or after-tax contributions to a 401(k)

Workers may also have an option in their retirement plan to contribute to a Roth 401(k) plan using after-tax contributions. While these contributions don’t provide the immediate tax deferral of the traditional 401(k) contribution, they do provide tax-free retirement income. Roth 401(k) contributions also help workers save after-tax dollars and avoid the income limit for direct contributions to a Roth IRA. To make a full Roth IRA contribution in 2024, single filers modified adjusted gross income (MAGI) must be under $146,000, and joint filers under $230,000. Alternatively, some workers and retirees may consider a Roth conversion. For large emergency expenses that may occur during retirement, such as medical-related expenses, retirees can use after-tax retirement savings in Roth accounts to avoid higher tax brackets.

Not sure what to do next with your catch-up contributions?

We offer a free simulator to see if you can reach your retirement savings goal.

When a Roth Conversion May Be Right for You

A Roth conversion typically moves pre-tax funds from an Individual Retirement Account (IRA) to a Roth IRA. Doing so adds income to the year when account holders convert, so may trigger additional income taxes. But, future withdrawals from the Roth IRA should be tax-free. We’ve discussed some research on this topic before in our article published in the Financial Planning Review. Ed McQuarrie, Emeritus Professor from Santa Clara University just published another article on the topic. It now appears on page 76 in the September 2024 edition of the Journal of Financial Planning. This post will highlight the key findings in this important research related to retirement income and estate planning. We also highlight how our retirement income calculator aligns with these insights for a retiree’s particular scenario.

Roth conversion article by Ed McQuarrie entitled "Net Present Value Analysis of Roth Conversions"

New research contribution

Prof. McQuarrie’s research focuses on the Roth conversion’s Net Present Value (NPV). NPV is an important metric used to value projects, which states that discounted future cash flows must sum to a positive number to add value to the project’s owner. His journal article highlights when NPV turns positive based on the time since the conversion occurred,

Figure 2 from Net Present Value Analysis of Roth Conversions by E. McQuarrie, Journal of Financial Planning, Sep 2024.

As Figure 2 demonstrates, a positive NPV occurs when the retiree reaches age 86. More or less favorable assumptions about future tax rates can decrease or increase the time for NPV to turn positive, and this article highlights a few insightful examples.

Risks in future tax code and individual circumstances

The article continues by discussing several risks faced by a Roth conversion. For example, since the U.S. Congress sets tax laws, taxpayers will never know for certain what income tax rates may be in the future. The Tax Cut and Jobs Act (TCJA) that expires in 2025 may or may not be extended or modified in ways that are favorable to a Roth conversion today. Also, consideration of an heir’s tax rate is important for retirees who have excess funds they wish to pass on after their death. Heirs at lower tax brackets, and certainly heirs who are charitable organizations who may not owe tax on IRA bequests, may benefit more financially in receiving assets from an IRA rather than a Roth IRA. Conversely, a surviving spouse utilizing the standard deduction could significantly benefit from a conversion before the passing of their spouse.

How to assess a Roth conversion for your situation

Given all these complexities, a thoughtful analysis is important before making a Roth conversion. One approach is to use software, like our Retirement Income Calculator. And, given this latest research, there are many nuances to consider before conducting a Roth conversion. This research article nicely highlights four scenarios when a conversion is the least risky and four scenarios when they are most risky and is worthy of review for anyone considering a Roth conversion in the coming years.

Bond funds continue to challenge investors

Bond funds continue to challenge investors seeking less risk from the stock market, but also retaining buying power. My favorite writer Jason Zweig also wrote about this recently, along with many of his readers’ opinions. In this post, we illustrate what’s been happening over the last year since we last wrote about bond ETFs.

Bond funds and their time to maturity

Bond fund performance over the last year appears to still be heavily dependent on their time to maturity. As the image below shows, the total return of the shortest-term U.S. treasury bill ETF (ticker: BIL) was gradual and positive. The intermediate-term bond fund (ticker: AGG) nearly broke even for the last 12 months. The long-term bond fund (ticker: TLT) was most sensitive to rising interest rates and had the largest loss and most volatility over the past 12 months.

Bond ETFs with shorter terms to maturity

Staying with shorter-term ETFs has become much easier with several options for investors to consider. Here is a short list to consider:

SPDR Bloomberg 1-3 Month T-Bill ETF (ticker: BIL)
iShares Short Treasury Bond ETF (ticker: SHV)
Goldman Sachs Access Treasury 0-1 Year ETF (ticker: GBIL)
iShares 0-3 Month Treasury Bond ETF (ticker: SGOV)

Referring to the image above, we see that the SPDR Bloomberg 1-3 Month T-bill ETF returned 5.3%. And, as we have written about previously, this return is exempt from state taxes. This exemption is significant for states like California and Hawaii, but irrelevant for states like Texas and Florida that have no state income tax. In any case, with current inflation around 3%, these short-term investments are helping ETF investors to maintain and slightly grow their buying power.

Optimal decisions under price dynamics for Roth conversions

As the April 15th tax deadline approaches, many retirees may be considering the trade-offs associated with Roth conversions. Seeking optimal decisions can be challenging! In this post, we highlight a peer-reviewed journal article recently published in the Financial Planning Review and add to our previous discussion on this topic.

Timing your tax payments

Ordinary income taxes may occur during retirement from tax-deferred account distributions, like withdrawals from a 401(k) plan. However, by conducting a Roth conversion, a retiree can move these tax-deferred assets to a Roth account where future withdrawals are generally tax-free. But, to do so, they may owe taxes on the distribution. There are other rules too. For example, retirees may not convert required minimum distributions. Nevertheless, many financial planners consider Roth conversions when a client’s taxable income is unusually low, thereby taking advantage of lower tax rates in our progressive tax system.

Key Insights

This article provided many important insights when seeking optimal decisions on Roth conversions.

If funding the Roth conversion from retirement assets, the conversion will be solely dependent on future tax rates. Thus, the conversion will have a positive (negative) payoff if future tax rates are higher (lower) than the rate paid to convert.
If funding the Roth conversion from non-retirement taxable assets, the cost basis of these assets plays an important role. So, the lower the cost basis of these assets used to fund the tax liability caused by the conversion, the less likely that a positive payoff will occur.
Using non-retirement assets to fund the Roth conversion’s tax liability also creates a payoff dependent on market returns. Stronger market returns lead to a greater payoff. Also, the calculus of this optimal decision changes significantly whether the non-retirement assets will ever need to be used by the retiree, or if they will receive a step-up in cost basis when left to an heir.

The bottom line on optimal decisions for Roth conversions

Making an optimal decision on converting tax-deferred retirement funds to a Roth IRA is not simple. As the results of this research show, there may be situations where it is worthy of consideration. But, there are also many scenarios when Roth conversions should not be pursued. Not sure how it may affect your situation?

Required Minimum Distributions in 2024

Happy New Year! In this post, we discuss some of the salient features of required minimum distributions (RMDs) for those in or nearing their retirement. We also provide a proactive tax-efficient strategy to help reduce the impact of RMDs.

What is an RMD and how does it apply to me?

As their name implies, required minimum distributions (RMDs) are amounts that need to be withdrawn, or “distributed”, from a retirement account. The retirement accounts that impose RMDs typically include those with pre-tax contributions and gains, such as 401(k), IRAs, and 403(b) plans.

Required Minimum Distributions (RMDs) are minimum amounts that IRA and retirement plan account owners generally must withdraw annually starting with the year they reach age 72 (73 if you reach age 72 after Dec. 31, 2022).
U.S. Internal Revenue Service FAQs

The amount of the RMD depends on the account holder’s age, assuming they did not inherit the retirement account. As the retiree ages, the proportion of RMD distributions, relative to their total account value, increases. For example, a retiree expected to live another 20 years based on the IRS life expectancy tables must withdraw 1/20th (or 5%) of their account value to satisfy RMDs.

Note:  This post has been prepared for informational purposes only, and is not intended to provide, and should not be relied on for, tax, legal or accounting advice. You should consult your own tax, legal and accounting advisors before engaging in any transaction.

Implications and Strategies for Tax Efficiency of Required Minimum Distributions

As this recent WSJ article articulated, there are several implications to RMDs on a retiree’s tax liabilities. First, after a strong year of market returns, RMDs will be even higher due to larger retirement account balances. These higher account values and subsequent RMDs could also push the retiree into a higher tax bracket. Lastly, RMDs could also trigger Net Investment Income Tax (NIIT) as well as higher Income-Related Monthly Adjustment Amounts (IIRMA).

A simple strategy to increase tax efficiency in retirement income is to plan for the future, and not always defer distributions from tax-deferred accounts, like IRA and 401(k) plans. We demonstrated in our award-winning peer-reviewed published manuscript how such a tax-efficient approach can produce 0.3% to 0.6% of additional return for a variety of retirees. Is similar planning beneficial to your situation? To find out, we encourage you to try out our retirement income planning tool recently updated for 2024 tax brackets.

Tax Loss Harvesting

As 2023 heads to a close, many investors are considering whether to sell investments at a loss, often referred to as tax loss harvesting. In this post, we explain this tax opportunity and the financial benefit possible from it. We also describe a pitfall that investors should avoid to achieve the benefit of tax loss harvesting.

notebook and calculator on green surface — Photo by Nataliya Vaitkevich on Pexels.com

Short-term or long-term?

Why is tax loss harvesting important? To begin, ETF investors must understand the difference between short-term and long-term gains or losses. An investor realizes a short-term loss when they sell an ETF held for less than one year. In general, taxes on losses on short-term investments in securities like ETFs occur at a higher rate than those gains realized from short-term investments. For taxpayers at the highest rates, the short-term rate is 37%, and the long-term rate is 20%.

So, if an investment is below its purchase price within one year of holding it, an investor can sell it and realize a short-term loss. This short-term loss can be deducted from any short-term gains, like those from bond or money market investments. Consequently, an investor’s income tax may be reduced.

Pitfalls

The most obvious pitfall is the wash sale rule. Investors may not obtain a tax benefit if they sell an ETF for a loss within 30 days, and then rebuy it. Consequently, such a violation eliminates the opportunity for tax-loss harvesting. Investors wishing to stay invested in the markets can opt to buy a different ETF that is not “substantially identical” and not wait 30 days.
