Local governments and public agencies issue municipal bonds to raise money for projects

Municipal bonds are issued by cities, counties, states, and special districts — not by the federal government or private companies. When a city needs to build a new school or repair a bridge, it often borrows money by selling bonds to investors rather than raising taxes all at once. The investor buys the bond, the government uses the money for the project, and the investor receives interest payments over time.

The issuer is always a public entity with the legal power to borrow on behalf of its residents. This includes city councils, county commissions, state legislatures, school districts, water authorities, and transit agencies. Each of these bodies can issue bonds within the limits set by state law and their own charters.

Key Takeaways

  • Municipal bonds are issued only by government bodies and public agencies, never by private companies or the federal government.
  • Common issuers include cities, counties, states, school districts, and special-purpose authorities like water or transit agencies.
  • The issuer borrows money by selling bonds to investors and repays the loan through tax revenue, user fees, or other dedicated income sources.
  • State law determines what types of projects a local government can finance through bonds and how much debt it can take on.

Cities and counties issue bonds for infrastructure and services

A city or county government issues bonds when it needs capital for projects that serve the public — roads, libraries, fire stations, water systems, or courthouses. The city council or county commission votes to authorize the bond issue, and the finance department handles the sale to investors.

The money raised goes into a dedicated fund for that specific project. Once the project is complete, the government repays bondholders from its general revenue (taxes), from fees charged to users (like water bills), or from a dedicated tax stream (like a sales tax increase voters approved). The repayment schedule is set when the bond is issued and typically runs 10 to 30 years.

States issue bonds for highways, universities, and statewide programs

State governments issue bonds for projects that benefit the entire state — highway systems, university buildings, environmental cleanup, or affordable housing programs. The state legislature authorizes the bond, and the state treasurer's office manages the sale and repayment.

State bonds often carry lower interest rates than city or county bonds because states have larger, more diverse tax bases and are seen as lower risk by investors. However, states are also subject to debt limits set by their own constitutions or laws, which can restrict how much they can borrow.

School districts and special authorities issue bonds for specific purposes

School districts issue bonds to build or renovate schools, purchase buses, or upgrade technology systems. A school board votes to authorize the bond, and the district's finance office manages the sale. Repayment comes from the district's operating budget, which is funded by property taxes and state aid.

Special-purpose authorities — water districts, sewer authorities, transit agencies, port authorities, and hospital districts — also issue bonds for their specific missions. A water district might issue bonds to build a new treatment plant; a transit agency might issue bonds to purchase buses or expand rail lines. These agencies are created by state law and have their own governing boards that vote on bond issues.

Voter approval is often required before an issuer can sell bonds

In many states, local governments must hold a public vote before issuing bonds, especially for large amounts or for projects not already authorized by law. The ballot measure tells voters the project, the amount to be borrowed, and the expected tax impact. If voters approve, the government can proceed; if they reject it, the bond cannot be issued.

State governments sometimes require voter approval for bonds, but not always — it depends on the state constitution and the type of project. School districts almost always need voter approval for construction bonds. Special authorities may or may not, depending on state law and the authority's charter.

Rating agencies assess the issuer's creditworthiness before bonds are sold

Before an issuer can sell bonds to the public, rating agencies like Moody's, Standard & Poor's, and Fitch evaluate the issuer's financial health. They look at tax revenue trends, debt levels, pension obligations, and the issuer's history of paying debts on time. The rating — typically ranging from AAA (highest) to C or D (lowest) — tells investors how risky the bond is.

A city with stable tax revenue and low debt gets a higher rating and can sell bonds at lower interest rates. A city with declining revenue or high debt gets a lower rating and must offer higher interest rates to attract investors. The rating directly affects the cost of borrowing: a difference of one rating level can mean hundreds of thousands of dollars in extra interest over the life of a bond.

Underwriters and financial advisors help issuers structure and sell bonds

Most municipal bond issuers work with an underwriter — a financial firm that buys the bonds from the issuer and resells them to investors. The underwriter handles the legal paperwork, sets the interest rate, and manages the marketing. The issuer pays the underwriter a fee, usually a percentage of the total bond amount.

Issuers also hire financial advisors to help structure the bond issue — deciding how much to borrow, what repayment schedule to use, and whether to issue taxable or tax-exempt bonds. These advisors are paid a separate fee and work on behalf of the issuer, not the underwriter or investors.

Frequently Asked Questions

Can a private company issue a municipal bond?

No. Municipal bonds are issued only by government bodies and public agencies. A private company can issue corporate bonds, but those are not municipal bonds and do not carry the same tax benefits. Some private companies do work with governments on public-private partnerships, but the government is still the issuer of any bonds involved.

What happens if an issuer cannot repay its bonds?

The issuer is legally obligated to repay bondholders, and failure to do so is called default. Defaults are rare but do happen — usually when a city or district faces a severe financial crisis. When default occurs, bondholders may recover some or all of their money through court action or a restructuring plan, but recovery is often incomplete.

Can a city issue bonds without voter approval?

It depends on state law and the type of project. Many states allow cities to issue bonds for certain purposes — like refinancing existing debt or making emergency repairs — without a vote. Large new projects typically require voter approval. Check your state's constitution or your city's charter to learn the rules in your area.

Who decides how much a government can borrow through bonds?

State law sets the overall limit on how much debt a local government can carry, usually as a percentage of the property tax base or assessed value. Within that limit, the local government's elected officials (city council, county commission, school board) decide whether to issue bonds for specific projects. Voters may also have a say if state law requires a public vote.

Why do some issuers use underwriters instead of selling bonds directly?

Underwriters have relationships with investors and expertise in pricing and marketing bonds. Using an underwriter reduces the issuer's work and risk, though it costs a fee. Some large, experienced issuers do sell bonds directly to investors, but most rely on underwriters to reach a wider market and get a better price.
