Understanding Tax Equivalent Yield
Tax equivalent yield calculates what taxable bond yield would be needed to match the after-tax return of a tax-exempt bond. This comparison helps investors determine whether municipal bonds or taxable bonds offer better value based on their tax situation.
Tax Equivalent Yield Formula
Basic Formula
- Tax Equivalent Yield = Tax-Exempt Yield / (1 - Tax Rate)
- Shows required taxable yield for equivalent after-tax return
- Higher tax rates increase the equivalent yield
- Used for apples-to-apples bond comparisons
Example Calculation
- Muni bond yield: 3.5%
- Marginal tax rate: 32%
- Tax equivalent yield: 3.5% / (1 - 0.32) = 5.15%
- Taxable bond needs 5.15% to match after-tax return
Tax-Exempt vs Taxable Bonds
Key Differences and Considerations
Understanding the trade-offs between bond types
Tax-Exempt Bonds (Municipals)
- Interest income exempt from federal taxes
- May be exempt from state/local taxes
- Lower nominal yields
- Credit risk varies by issuer
- AMT considerations
Taxable Bonds (Corporates/Treasuries)
- Interest income subject to federal taxes
- Higher nominal yields
- Different credit quality spectrum
- Liquid and transparent markets
- No AMT issues
Factors Affecting Tax Equivalent Yield
| Factor | Impact on Equivalent Yield | Reason |
|---|---|---|
| Tax Rate | Higher tax rate ? Higher equivalent yield | Greater tax savings from tax-exempt bonds |
| Muni Yield | Higher muni yield ? Higher equivalent yield | Direct relationship in the formula |
| State Taxes | State tax exemption ? Even higher equivalent yield | Additional tax benefits |
| AMT Status | AMT taxable ? Lower equivalent yield | Reduced tax benefits |
Tax Brackets and Equivalent Yields
Federal Tax Brackets (2023)
- 10% bracket: 3.5% muni = 3.89% equivalent
- 22% bracket: 3.5% muni = 4.49% equivalent
- 24% bracket: 3.5% muni = 4.61% equivalent
- 32% bracket: 3.5% muni = 5.15% equivalent
- 35% bracket: 3.5% muni = 5.38% equivalent
- 37% bracket: 3.5% muni = 5.56% equivalent
Break-Even Analysis
- Find tax rate where yields are equal
- Break-even rate = 1 - (Muni yield / Taxable yield)
- Above break-even: Munis more attractive
- Below break-even: Taxables more attractive
- Consider state taxes and AMT
