Municipal Bond
Municipal Bond
Debt securities issued by state and local governments to finance public projects, with interest typically exempt from federal income tax. Two main types: General Obligation (GO) bonds backed by taxing authority, and Revenue bonds backed by specific project revenue. Credit risk varies based on issuer financial strength and bond structure.
A city issues a $50 million GO bond to build a new school, backed by property tax revenue. Separately, the same city issues a $30 million revenue bond to build a toll bridge, backed only by toll collections from bridge users.
Students often confuse GO bonds (backed by taxing power, require voter approval) with revenue bonds (backed by project revenue, no voter approval needed). Another common error is forgetting that tax-equivalent yield makes munis more attractive in higher tax brackets, not all tax brackets.
How This Is Tested
- Distinguishing between General Obligation bonds (taxing power) and Revenue bonds (project revenue)
- Calculating tax-equivalent yield to compare municipal bonds with taxable alternatives
- Determining municipal bond suitability based on client tax bracket and investment objectives
- Understanding credit risk differences between GO bonds and revenue bonds
- Recognizing which municipal bonds are subject to AMT (Alternative Minimum Tax)
Regulatory Limits

Example Exam Questions
Test your understanding with these practice questions. Select an answer to see the explanation.
Jennifer, age 52, is in the 35% federal tax bracket and lives in California. She has $200,000 to invest and wants steady income with tax efficiency. Her adviser presents two options: a California municipal bond yielding 3.9% tax-free, or a corporate bond yielding 5.5% taxable. Which recommendation would be most appropriate for Jennifer?
B is correct. The municipal bond's tax-equivalent yield is 3.9% รท (1 - 0.35) = 3.9% รท 0.65 = 6.0%, which exceeds the corporate bond's 5.5% taxable yield. Since Jennifer is in a high tax bracket, the tax-exempt municipal bond provides superior after-tax returns. As a California resident buying California munis, she may also receive state tax exemption, further enhancing returns.
A is incorrect because it ignores the tax benefit, focusing only on nominal yield rather than after-tax return. C is incorrect because it misstates credit risk; investment-grade municipal bonds typically have lower default rates than similarly-rated corporate bonds. D is incorrect because only municipal bond interest is tax-exempt, not corporate bond interest, and the state tax exemption applies only to in-state municipal bonds.
The Series 65 exam frequently tests tax-equivalent yield calculations and municipal bond suitability based on tax brackets. Understanding when municipal bonds provide superior after-tax returns is essential for making appropriate client recommendations. Questions often compare municipal bonds to taxable alternatives for clients in various tax brackets, testing whether you can identify which investment maximizes after-tax income.
What is the primary source of repayment for a municipal General Obligation (GO) bond?
C is correct. General Obligation (GO) bonds are backed by the full faith, credit, and taxing power of the issuing municipality. This includes property taxes (ad valorem taxes), income taxes, sales taxes, and other general revenues. The issuer's ability to raise taxes to meet debt obligations makes GO bonds generally safer than revenue bonds.
A (project revenue) is incorrect because this describes revenue bonds, not GO bonds. B (U.S. government backing) is incorrect because municipal bonds are state and local government obligations, not backed by federal guarantee. D (specific collateral) is incorrect because GO bonds are unsecured by physical assets; they rely on the issuer's taxing authority rather than pledged property.
The distinction between GO bonds and revenue bonds is one of the most frequently tested concepts on the Series 65 exam. Understanding that GO bonds are backed by taxing power (making them generally lower risk) while revenue bonds depend on project success is critical for credit risk assessment. Exam questions often present scenarios asking which type provides greater security or which requires voter approval.

Access Free BetaAn investor in the 37% federal tax bracket is evaluating a municipal bond yielding 4.5%. What taxable yield would provide an equivalent after-tax return?
B is correct. The tax-equivalent yield formula is: municipal yield รท (1 - tax bracket) = 4.5% รท (1 - 0.37) = 4.5% รท 0.63 = 7.14%. This means a taxable bond would need to yield 7.14% to provide the same after-tax return as the 4.5% tax-exempt municipal bond for an investor in the 37% bracket.
A (6.15%) uses an incorrect denominator calculation. C (2.84%) incorrectly calculates the after-tax yield of a 4.5% taxable bond (4.5% ร 0.63 = 2.84%), which is the reverse of what the question asks. D (4.50%) is simply the municipal yield without any tax adjustment, ignoring the tax benefit entirely.
Tax-equivalent yield calculations appear on virtually every Series 65 exam, particularly in comparative analysis and suitability questions. This formula is essential for determining whether municipal bonds are appropriate for clients based on their tax situation. The exam tests whether you understand that higher tax brackets make municipal bonds increasingly attractive, and that low-bracket investors typically benefit more from taxable bonds with higher nominal yields.
All of the following statements about municipal bonds are accurate EXCEPT
C is correct (the EXCEPT answer). Revenue bonds are NOT backed by the full faith and credit of the issuing government. They are backed only by the revenue generated from the specific project they finance (tolls, user fees, lease payments, etc.). This fundamental distinction makes revenue bonds generally riskier than GO bonds from the same issuer.
A is accurate: municipal bond interest is exempt from federal income tax for most issues (except some private activity bonds subject to AMT). B is accurate: GO bonds typically require voter approval because they pledge the municipality's taxing power and create general obligations. D is accurate: municipal bonds purchased by residents of the issuing state often qualify for state tax exemption ("double tax-free" or "triple tax-free" if also exempt from local taxes).
The Series 65 exam tests your ability to distinguish between GO bonds and revenue bonds across multiple dimensions: backing, approval requirements, credit risk, and typical yields. Understanding that revenue bonds depend on project success rather than taxing power is critical for credit analysis. Questions frequently present scenarios asking which bond type is safer or which requires voter authorization.
A municipality issues a revenue bond to finance construction of a new airport terminal, with debt service paid from airline lease payments and passenger facility charges. Which of the following statements are accurate?
1. This bond requires voter approval before issuance
2. The bond is backed by the municipality's taxing authority
3. Bondholders face risk if airline traffic declines significantly
4. This bond would typically yield more than a GO bond from the same issuer
B is correct. Statements 3 and 4 are accurate.
Statement 1 is FALSE: Revenue bonds do NOT require voter approval because they are backed by project revenue, not the municipality's taxing power or general obligation.
Statement 2 is FALSE: Revenue bonds are NOT backed by taxing authority. They are secured only by the specific revenue stream from the financed project (in this case, airline lease payments and passenger facility charges).
Statement 3 is TRUE: Bondholders face risk if the revenue source declines. If airline traffic drops significantly, lease payments and passenger fees could decrease, potentially jeopardizing debt service payments.
Statement 4 is TRUE: Revenue bonds typically yield more than GO bonds from the same issuer because they carry higher credit risk. The project-specific revenue backing is generally considered less secure than the broad taxing power backing GO bonds.
The Series 65 exam tests detailed understanding of revenue bond characteristics and how they differ from GO bonds. Revenue bonds present higher risk because they depend on project success rather than taxing authority, which results in higher yields to compensate investors. Questions often present specific project scenarios (airports, toll roads, hospitals, stadiums) and test whether you understand the revenue sources, risk factors, and structural differences from GO bonds.
๐ก Memory Aid
Think "GO" = Government Owns the tax power (general obligation bonds backed by taxes). Revenue bonds = Risky (depend on project success, no tax backing). For tax math: Higher bracket = Munis better. Formula: Divide muni yield by (1 minus your tax bracket) to get the taxable equivalent.
