Taxes or Tolls: Who Pays the Bondholders?
🏛️ A city borrows for a new school and a new toll bridge. One bond is paid from property taxes, the other only if drivers keep paying tolls. The SIE wants you to know which is which.
💡 Key idea
GO = paid by taxpayers, needs voters. Revenue = paid by users, needs a feasibility study.
🧠 Why it matters
A GENERAL OBLIGATION (GO) bond is backed by the issuer's full faith and credit: its power to tax. Local GOs lean on property (ad valorem) taxes; states use income and sales taxes. Because taxpayers are on the hook, GOs usually need VOTER APPROVAL and count against debt limits. They fund things that earn no money, like schools and parks. A REVENUE bond is paid only from a project's income: tolls, water bills, airport fees. Before issuing, a FEASIBILITY STUDY checks the project can earn enough. No taxing power stands behind it. Hybrids: DOUBLE-BARRELED (project revenue first, plus GO taxing power), MORAL OBLIGATION (a state may, but is not legally bound to, cover a shortfall), SPECIAL TAX (backed by one tax, such as a hotel or fuel tax).
📈 In the real world
🌉 Councilwoman Ortiz asks why the bridge bonds skipped the ballot. The finance director explains: they are revenue bonds, repaid only from tolls, so no tax dollars are pledged. The engineers' feasibility study, not the voters, had to show traffic would cover the debt. The new library, with no income of its own, went on the ballot as a GO bond.
📌 Takeaways
- GO bonds rest on taxing power; local GOs on property taxes
- Revenue bonds rest on project income and a feasibility study
- Double-barreled = revenue plus GO backing; moral obligation = no legal promise
📖 Terms in this lesson
General obligation bond (GO): A municipal bond backed by the issuer's full faith, credit and taxing power, often requiring voter approval.
Revenue bond: A municipal bond repaid only from the income of a specific project, such as tolls or water fees.
Feasibility study: A study done before a revenue bond issue to estimate whether the project will earn enough to repay the debt.
Double-barreled bond: A municipal bond repaid from a project's revenue and also backed by the issuer's taxing power.
Moral obligation bond: A municipal revenue bond that a state legislature may, but is not legally required to, support if revenues fall short.
GO = TAXES, REVENUE = USERS: General obligation bonds are repaid from taxes; revenue bonds are repaid by users of the project, such as tolls or fees.
✅ Test yourself
Which document is most closely associated with a revenue bond issue rather than a GO issue?
- A voter referendum on the debt
- A pledge of ad valorem property taxes
- A statutory debt-limit calculation
- A feasibility study of the project
Answer: D · A feasibility study of the project
Revenue bonds are repaid from project income, so a feasibility study tests whether that income will be enough. Voter approval, property-tax pledges and debt-limit checks belong to GO bonds, which are backed by taxing power.
A water-system bond is repaid from user fees, and the city also pledges its taxing power if fees fall short. What is this bond called?
- A special tax bond
- An industrial revenue bond
- A moral obligation bond
- A double-barreled bond
Answer: D · A double-barreled bond
Two sources of payment, project revenue plus GO taxing power, make a double-barreled bond. A moral obligation bond has no legally binding backup, a special tax bond rests on one named tax, and an industrial revenue bond depends on a corporate user.
What makes a moral obligation bond different from a GO bond?
- It is backed only by the issuer's property taxes
- It must pass a feasibility study and a public referendum first
- The legislature is not legally bound to cover a shortfall
- Its interest is always subject to federal income tax
Answer: C · The legislature is not legally bound to cover a shortfall
With a moral obligation bond, the legislature may appropriate money to cover a deficiency but is not legally bound to. A GO bond carries a legal pledge of taxing power. Tax status does not depend on the moral obligation feature.
