“Municipal Bonds Belong in Taxable Accounts,” Say Charles Schwab Investment Experts

The yield on a bond is only half the story. What lands in your bank account after taxes is the half that matters, and for high earners, that distinction can flip the math on what looks like the better investment.

On a recent episode of Charles Schwab’s On Investing podcast titled “Rising Yields Highlight Muni Opportunities,” the hosts walked through why municipal bonds, despite their lower headline yields, often beat corporates and Treasuries for investors in the top brackets. With the 10-year Treasury yielding 4.56% as of May 22, 2026 and the 20-year and 30-year both at 5.03%, the comparison is more than academic.

Quick Read

• Municipal bonds with 4% yields can deliver higher after-tax returns than 5% taxable bonds for investors in the 37% federal bracket when held in taxable accounts, with the break-even occurring around the 32% to 37% federal tax bracket.

• The Federal Reserve’s interest rate cuts from 4.5% in May 2025 to 3.75% today have narrowed the yield gap between 5% Treasuries and 4% municipal bonds, making the tax advantage of munis more valuable in the current environment.

The Counterintuitive Math

Munis are issued by cities, states, and local governments to fund roads, schools, and hospitals. The hosts noted that “they pay interest income that’s generally exempt from federal income taxes,” and buying bonds from your home state can also exempt the income from state taxes. The trade-off: munis “offer yields that are often lower than that of a comparable corporate or a Treasury bond.”

The podcast laid out a clean example. Imagine a 4% municipal bond next to a 5% taxable bond, each on $1,000 of principal.

• Investor in a 10% bracket: The taxable bond keeps $45 after tax; the muni keeps $40. Taxable wins.

• Investor in a 40% bracket: The taxable bond keeps just $30 after tax; the muni keeps the full $40. Muni wins.

The lower stated yield delivers the higher take-home return once the tax bite gets steep enough. For context, the top federal marginal rate for tax year 2026 remains 37% for single filers with incomes above $640,600 and married couples filing jointly above $768,700. Layer on state income tax in places like California or New York and the effective marginal rate easily clears 40%.

Two Questions Before You Buy

The hosts boiled the decision down to a simple framework.

1. What is your marginal tax bracket? The higher it climbs, the more valuable tax-exempt income becomes. Investors in the 32% to 37% federal brackets are where munis start outshining corporates and Treasuries on an after-tax basis. To calculate your personal break-even, divide the muni yield by one minus your marginal tax rate. That gives the taxable-equivalent yield. A 4% muni for a 37% federal filer equates to roughly 6.35% pre-tax.

2. What kind of account are you using? The hosts were emphatic: “the type of investment account that you’re investing in really matters.” Munis belong in taxable brokerage accounts. Holding them inside an IRA or 401(k) throws away the entire tax advantage you paid for in the form of a lower yield. You’re essentially buying a worse bond.

Why the Setup Looks Good Right Now

The current rate environment makes the comparison particularly live. The Fed has cut its target rate from 4.5% in May 2025 to 3.75% today, with three consecutive cuts since September 2025. That has compressed yields on short-duration taxable instruments while longer Treasuries still offer attractive nominal returns. A 5% taxable yield is achievable in 20-year and 30-year Treasuries; tax-free munis in the 4% range compete directly with intermediate maturities at 4.19% to 4.50%.

Inflation context matters too. CPI is running near the Fed’s 2% target, which means real after-tax returns on a 4% tax-free muni are positive and meaningful for someone in a top bracket. The same cannot be said for a 5% taxable Treasury once a 37% federal rate and any state tax are applied.

The Practical Takeaway

Munis are a tool. They reward investors who do two pieces of arithmetic before clicking buy: their marginal rate and their account location. For the right investor in the right account, a 4% tax-free coupon quietly outperforms a 5% taxable one. For everyone else, the math points the other way.
