You buy municipal bonds through a broker, bank, or directly from the issuer, and the process depends on which route you choose

Municipal bonds are debt issued by states, cities, and other local governments to fund projects like schools, roads, and water systems. To own one, you need an account with a financial institution that sells them, money to invest, and a way to place an order. The three main routes are a full-service broker (who gives information but charges commissions), a discount broker (who executes trades with lower fees), or directly from the issuer through a program called Treasury Direct for certain bonds, or through a municipal bond fund if you want to own many bonds at once instead of individual ones.

The actual purchase works like buying a stock: you place an order, the broker finds a seller, the trade settles (usually within two business days), and the bond appears in your account. The price you pay depends on whether the bond is newly issued or trading on the secondary market, and whether interest rates have moved since it was first sold. You will also pay any applicable fees or markups, which vary widely by broker and bond type.

Key Takeaways

  • You need a brokerage account with a bank or broker that handles municipal bonds; not all brokers offer them, so check first.
  • New municipal bonds are usually sold through underwriters during the initial offering period, while existing bonds trade on the secondary market at prices that change with interest rates.
  • The cost to buy includes the bond price itself plus any broker markup or commission, which can range from nothing to several hundred dollars depending on the firm and bond.
  • Municipal bonds held to maturity return your principal plus interest, but selling before maturity means you receive whatever the current market price is, which may be less than you paid.
  • You can buy individual bonds or invest in a municipal bond fund or exchange-traded fund (ETF) if you want diversification without picking specific bonds.

Opening a brokerage account that sells municipal bonds

Not every brokerage offers municipal bonds, so your first step is confirming that the firm you want to use actually sells them. Large banks like Fidelity, Charles Schwab, and Vanguard all offer municipal bonds to their customers. Smaller or discount brokers may not, or may limit which bonds they can access. Call the firm or check their website under "fixed income" or "bonds" to see whether municipal bonds appear in their product list.

Once you have confirmed they sell municipal bonds, open an account the way you would for any brokerage account: provide your name, Social Security number, address, and employment information. The firm will ask what type of account you want — a regular taxable account, an IRA, a trust account, or another structure. This matters because the tax treatment of municipal bond interest depends partly on the account type and your state of residence. You will also need to fund the account by linking a bank account or transferring money from another brokerage.

The entire process usually takes a few days to a week. Some firms offer same-day or next-day account opening for certain account types, but municipal bond trading itself cannot happen until your account is fully set up and funded.

Finding and comparing municipal bonds before you buy

Once your account is open, you can search for municipal bonds using your broker's bond search tool. You will filter by maturity date (when you want your money back), credit rating (how safe the issuer is), yield (the interest rate), and sometimes by state (if you want bonds from your home state for state tax benefits). The search results show you bonds currently available for sale, their prices, and the yield you would receive if you held them to maturity.

The price of a municipal bond on the secondary market (bonds already issued and trading between investors) moves opposite to interest rates. If rates have risen since the bond was issued, the bond's price falls below its face value, and you buy it at a discount. If rates have fallen, the price rises above face value, and you pay a premium. The yield shown in the search results already accounts for this price movement, so you can compare bonds fairly even if they have different prices.

Before you buy, check the bond's official statement, which is a document filed with the Municipal Securities Rulemaking Board (MSRB) that describes the issuer's finances, the project the bond funds, and any risks. Your broker can usually link you to this document, or you can search for it on the MSRB's Electronic Municipal Market Access (EMMA) system, which is free and public. Reading the official statement takes time but tells you whether the issuer has a history of paying on time and whether the project itself is sound.

Placing an order and understanding the costs

When you find a bond you want to buy, you place an order through your broker's platform the same way you would order a stock. You specify how many bonds you want (they are usually sold in units of $5,000 face value), and the broker searches for sellers. The order may fill when ready if the bond is actively traded, or it may take hours or days if it is less common.

The price you see on the screen is the "ask" price — what sellers want. Your broker may add a markup on top of that, which is how they make money on the trade. Markups on municipal bonds are not always transparent and can range from nothing to several hundred dollars per bond depending on the broker and how common the bond is. Discount brokers often charge lower markups than full-service brokers, but you do not get investment information. Ask your broker what the markup is before you confirm the order.

The trade settles two business days after you place the order, meaning the bond arrives in your account and the money leaves your bank account. From that point forward, you own the bond and will receive interest payments, usually twice a year, directly into your account.

Buying new municipal bonds during the initial offering

New municipal bonds are sold during an initial offering period, usually lasting a few days to a week. During this time, the underwriter (the bank or firm managing the sale) offers the bonds at a fixed price set by the issuer. Once the offering period closes, the bonds move to the secondary market and their price begins to fluctuate with interest rates.

Buying during the initial offering can sometimes be cheaper because there is no secondary market markup — you pay the offering price set by the underwriter. However, you may not have as much choice in maturity dates or yields, because the issuer only offers the bonds they have decided to sell. Your broker will notify you when new offerings are available, or you can search your broker's platform for "new issues" or "primary offerings."

The process is the same as buying a secondary market bond: you place an order, the trade settles in two business days, and you own the bond. The main difference is that you are buying directly from the underwriter rather than from another investor.

Municipal bond funds and ETFs as an alternative to individual bonds

If you do not want to pick individual bonds, you can buy a municipal bond fund or municipal bond ETF, which holds many bonds in one investment. A fund is managed by a professional who selects the bonds; an ETF tracks an index of municipal bonds. Both let you own a diversified portfolio with a single purchase, and both charge annual fees (called expense ratios) that range from under 0.1% to over 0.5% per year depending on the fund.

The trade-off is that you give up control over which specific bonds you own, and you cannot hold the fund to maturity the way you can with an individual bond. The fund's price moves daily with interest rates and the credit quality of the bonds inside it. However, funds are simpler if you have a small amount to invest, because individual bonds usually require at least $5,000, and buying several different bonds to diversify can be expensive.

You buy a municipal bond fund or ETF the same way you buy a stock: through your brokerage account, with one order, and the trade settles in one or two business days. The fund or ETF then holds the bonds for you and distributes the interest income to you, usually monthly or quarterly.

What happens after you buy: holding, selling, and maturity

Once you own a municipal bond, you receive interest payments on a schedule set when the bond was issued — usually twice a year on specific dates. The interest is deposited into your brokerage account as cash, which you can reinvest, spend, or leave sitting. If the bond is held in a taxable account, you will owe federal income tax on the interest (though many municipal bonds are exempt from federal tax, and some are exempt from state tax too, depending on where you live and where the bond was issued).

If you need to sell the bond before it matures, you place a sell order through your broker. The bond sells at whatever the current market price is, which may be higher or lower than what you paid. If interest rates have fallen since you bought it, you can sell for a profit. If rates have risen, you will sell at a loss. The sale settles in two business days, and the proceeds appear in your account as cash.

If you hold the bond until maturity, the issuer returns your original investment (the face value) plus the final interest payment. You do not need to do anything — the payment happens automatically on the maturity date. At that point, the bond is gone from your account and you have cash to reinvest or use elsewhere.

Frequently Asked Questions

Do I need a minimum amount of money to buy municipal bonds?

Individual municipal bonds are usually sold in units of $5,000 face value, so $5,000 is the typical minimum. Some brokers may allow smaller purchases or have different minimums. Municipal bond funds and ETFs often have lower minimums — sometimes as little as the price of one share, which can be under $100. Check your broker's requirements.

Can I buy municipal bonds directly from the city or state without a broker?

Some issuers sell bonds directly to the public during the initial offering, but you still need a way to hold and trade them, which usually means a brokerage account. A few states run direct purchase programs, but these are rare. For most municipal bonds, using a broker is the standard route.

What is the difference between buying a new bond and a bond on the secondary market?

New bonds are sold during the initial offering at a price set by the underwriter, usually with no secondary market markup. Secondary market bonds are sold by other investors and their price changes with interest rates. New bonds may be cheaper upfront, but secondary market bonds offer more choices in maturity and yield.

What happens if the city or state that issued my bond runs out of money?

Municipal bonds are backed by the issuer's ability to collect taxes or revenue from the project the bond funds. If an issuer defaults, you may not receive your full principal or interest payments. This is why checking the official statement and the issuer's credit rating before you buy is important — it tells you the risk of default.

Can I lose money on a municipal bond?

If you hold a bond to maturity and the issuer does not default, you get your full principal back. If you sell before maturity, you can lose money if interest rates have risen and the bond's market price has fallen. You can also lose money if the issuer defaults on the bond.
