General Obligation Bond
A general obligation bond is a municipal bond backed by an issuer's broad credit and taxing power rather than a single project revenue source.
Municipal bond pledge terms covering general obligation bonds, unlimited-tax support, limited-tax constraints, and moral obligation structures.
General obligation and moral obligation bonds are municipal pledge terms that describe how principal and interest are expected to be paid. The label matters because a full faith and credit pledge, an unlimited-tax pledge, a limited-tax pledge, and a nonbinding moral obligation can create very different credit evidence.
Use this branch when the key question is the issuer’s repayment commitment rather than a project revenue stream. A General Obligation Bond usually points to broad issuer credit and taxing power. An Unlimited Tax Bond is a stronger form of tax pledge when authorized by law. A Moral Obligation Bond is different because the support is not a legally binding full-faith-and-credit pledge.
Use Overlapping Debt to estimate the additional tax-supported debt of counties, school districts, transit authorities, and other governments sharing the issuer’s residents, property, or economic base.
| Pledge label | Main idea | Evidence to review |
|---|---|---|
| General obligation | Issuer pledges broad credit and taxing power, subject to law. | Official statement, tax base, budget, debt burden, voter authorization, legal limits, and continuing disclosures. |
| Unlimited tax | Issuer may levy taxes as needed for debt service, subject to the authorized pledge. | Voter approval, levy authority, debt-service schedule, assessed value, collection history, and legal cap analysis. |
| Limited tax | Tax pledge exists but is constrained by rate, amount, or legal limit. | Tax-rate cap, available levy margin, overlapping debt, budget pressure, and legal authority. |
| Moral obligation | Government may consider replenishing a reserve or shortfall, but appropriation is not legally required. | Reserve mechanics, budget recommendation covenant, appropriation history, issuer disclosures, and legislative risk. |
| Direct and overlapping debt | Focal issuer debt plus allocated shares of other jurisdictions’ debt supported by an overlapping base. | Included debt, geographic boundaries, allocation percentage, assessed value, population, and source date. |
Do not treat pledge labels as investment instructions. MSRB and SEC investor materials point readers back to official statements, continuing disclosures, ratings, trade prices, tax status, and independent credit review.
For project-backed debt, use Revenue and Project-Backed Municipal Bonds. For broader municipal bond context, return to Municipal, Public-Purpose, and Savings Bonds.
Choose a subsection first. Deeper term pages live inside each subsection, which keeps large topic hubs readable.

Overlapping debt estimates the share of debt from other public jurisdictions supported by taxpayers or property within a focal government's boundaries.
