How do tax‑equivalent yields work for municipal bonds?

Understanding Tax-Equivalent Yields for Municipal Bonds💡 Definition:A fixed-income investment where you loan money to a government or corporation in exchange for regular interest payments.

Investors often seek ways to maximize their returns while minimizing tax liabilities. Municipal bonds (munis) offer a unique advantage in this regard, as the interest they pay is typically exempt from federal income💡 Definition:Income is the money you earn, essential for budgeting and financial planning. taxes and sometimes state and local taxes as well. However, comparing these tax-exempt yields with taxable bonds can be challenging. This is where the concept of tax-equivalent yield💡 Definition:The income return on an investment, expressed as a percentage of the investment's cost or current market value. (TEY) comes into play. In this article, we'll explore how TEY works, why it matters, and how you can use it to make informed investment decisions.

What Is Tax-Equivalent Yield?

Tax-equivalent yield is a financial metric used to compare the yield of a tax-exempt municipal bond💡 Definition:A municipal bond is a debt security issued by local governments, offering tax-free interest to investors. to that of a taxable bond. It answers the question: What yield would a taxable bond need to offer to match the after-tax return💡 Definition:A tax refund is money returned to you by the government when you've overpaid your taxes, providing extra cash flow. of a municipal bond? This comparison allows investors to evaluate whether a municipal bond is a better option than a taxable bond, considering their specific tax situation.

Calculating Tax-Equivalent Yield

The formula for calculating TEY is straightforward:

[ \text{Tax-equivalent yield} = \frac{\text{Municipal bond yield💡 Definition:The return an investor earns on a bond, expressed as a percentage, which can be calculated as current yield (annual interest ÷ current price) or yield to maturity (total return if held until maturity).}}{1 - \text{tax rate}} ]

Here's how it works:

• Municipal Bond Yield: This is the yield offered by the municipal bond, typically expressed as a percentage.
• Tax Rate: This includes your marginal federal, state, and local tax rates combined.

For instance, if you have a municipal bond yielding 3% and your combined tax rate is 30%, the TEY would be:

[ \frac{3%}{1 - 0.30} = 4.28% ]

This means a taxable bond would need to yield at least 4.28% to provide the same after-tax return as the municipal bond.

Why Tax-Equivalent Yield Matters

Understanding TEY is crucial for several reasons:

• Comparison with Taxable Bonds: TEY allows you to make apples-to-apples comparisons between tax-exempt municipal bonds and taxable bonds, like corporate or Treasury bonds.
• Impact of Tax Brackets: Your marginal tax rate💡 Definition:The tax rate applied to your last dollar of income—the rate you pay on additional earnings. significantly impacts the TEY. Higher tax rates increase the TEY, making municipal bonds more attractive.
• State and Local Tax Considerations: If you live in the state issuing the municipal bond, you might also be exempt from state and local taxes, further enhancing the muni's appeal.

Real-World Examples

Scenario 1: Middle Income Investor

Consider an investor in the 22% federal tax bracket💡 Definition:The range of income taxed at a specific rate under the U.S. progressive tax system. looking at a municipal bond with a 4.5% yield. The TEY calculation would be:

[ \frac{4.5%}{1 - 0.22} = 5.77% ]

This investor would need a taxable bond yielding more than 5.77% to outperform the municipal bond on an after-tax basis💡 Definition:The original purchase price of an investment, used to calculate capital gains or losses when you sell..

Scenario 2: High Income Investor

A high-income investor in a 32% federal and 8% state tax bracket (totaling 40%) examines a 3% municipal bond yield. The TEY is:

[ \frac{3%}{1 - 0.40} = 5% ]

For this investor, a taxable bond must yield more than 5% to be competitive.

Common Mistakes and Considerations

• Ignoring State and Local Taxes: Not all municipal bonds are exempt from state and local taxes, especially if the investor resides out-of-state. Always consider your full tax situation in the TEY calculation.
• 💡 Definition:Tax on profits from selling investments like stocks, bonds, or real estate.Capital Gains💡 Definition:Profits realized from selling investments like stocks, bonds, or real estate for more than their cost basis.

• Tax Law💡 Definition:Regulation ensures fair practices in finance, protecting consumers and maintaining market stability. Changes: Changes in tax rates or laws can affect the attractiveness of municipal bonds and alter TEY calculations.
• Assumptions: TEY assumes you hold the bond until maturity and are subject to the stated tax rates. Early sales💡 Definition:Revenue is the total income generated by a business, crucial for growth and sustainability. or changes in your tax status can affect outcomes.

Bottom Line

Tax-equivalent yield is an invaluable tool for investors looking to compare municipal bonds with taxable bonds.
