How to buy municipal bonds

You buy municipal bonds through a broker — either a traditional brokerage firm, an online broker, or directly from a bond dealer. The process is straightforward: you open an account, fund it, search for bonds that match what you want to hold, and place an order. Unlike stocks, municipal bonds don't trade on a central exchange. Instead, they trade over-the-counter, meaning your broker finds a seller and executes the trade for you. The entire transaction typically takes a few days to settle.

Most individual investors buy municipal bonds through one of three routes: a full-service brokerage (where a broker helps you choose), an online brokerage platform (where you search and buy yourself), or directly from a municipal bond dealer. Each route has different costs and levels of guidance. You'll need to decide which fits your situation before you open an account.

Key Takeaways

  • Municipal bonds are sold over-the-counter through brokers, not on a central stock exchange, so your broker finds the seller and executes the trade.
  • You can buy through a full-service brokerage, an online platform, or directly from a bond dealer, each with different fees and levels of support.
  • Before buying, decide what you want: the maturity date (when you get your money back), the yield, and whether you want general obligation or revenue bonds.
  • Municipal bonds typically have a minimum purchase of $5,000 per bond, though some brokers allow smaller amounts through bond funds or laddered purchases.
  • Your broker will charge a markup or commission, which is built into the price you see — ask what you're paying before you confirm the trade.

Decide what type of municipal bond you want

Before you open an account or contact a broker, know what you're looking for. Municipal bonds come in two main types: general obligation bonds (backed by the issuer's tax revenue) and revenue bonds (backed by income from a specific project, like a toll road or water system). General obligation bonds are typically safer because they're backed by the full taxing power of the city or state. Revenue bonds carry more risk because they depend on the project generating enough money to pay bondholders.

You also need to decide on a maturity date — when you want your principal back. Bonds maturing in 5 years will pay less interest than bonds maturing in 20 years, but you'll get your money sooner. Many investors buy a mix of bonds with different maturity dates, a strategy called laddering, so they have cash coming back at regular intervals.

Finally, consider whether you want bonds from your home state (which may offer state tax exemption in addition to federal tax exemption) or bonds from any state. Bonds from your state are often called in-state bonds. If you live in a high-tax state like California or New York, in-state bonds can be significantly more valuable because you avoid both federal and state income tax on the interest.

Open an account with a broker

Choose a broker based on the type of service you want. Full-service brokerages like Merrill Lynch, Morgan Stanley, or UBS have advisors who can discuss your goals and recommend specific bonds, but they charge higher fees. Online brokerages like Fidelity, Charles Schwab, or E*TRADE let you search and buy bonds yourself with lower costs. Some brokers specialize in municipal bonds and may have better inventory or pricing.

When you open an account, you'll provide your name, address, Social Security number, and employment information. The broker will ask about your investment experience and financial situation. This is standard Know Your Customer (KYC) compliance — the broker is required to collect this information. You'll also choose the type of account: individual, joint, IRA, or trust.

After your account is approved, you'll fund it by transferring money from your bank. Most brokers allow electronic transfers, checks, or wire transfers. The money typically arrives within a few business days. Once it's in your account, you're ready to search for bonds.

Search for bonds that fit your criteria

Log into your broker's platform and use their bond search tool. You'll filter by state, maturity date, credit rating, and yield. If you're using an online broker, you'll see the bonds available and their prices. If you're working with a full-service broker, you'll call or email your advisor with your criteria, and they'll send you a list of options.

Pay attention to the credit rating — this is a letter grade (AAA, AA, A, BBB, and lower) that tells you how likely the issuer is to pay you back. Bonds rated AAA or AA are considered very safe. Bonds rated BBB or lower carry more risk but pay higher interest. Most individual investors stick with bonds rated A or higher unless they're experienced.

Look at the yield to maturity (YTM), which tells you the total return you'll get if you hold the bond until it matures. This is more useful than the coupon rate (the interest rate printed on the bond) because it accounts for the price you're paying. If a bond is selling at a discount, the YTM will be higher than the coupon rate. If it's selling at a premium, the YTM will be lower.

Understand the costs and pricing

Municipal bonds don't have a transparent, published price like stocks do. Instead, your broker quotes you a price that includes their markup or commission. The markup is built into the price you see — you won't see a separate fee line item. This is normal, but it means you should ask your broker what the markup is before you confirm the trade.

Markups on municipal bonds typically range from 0.5% to 2% of the bond's value, depending on the bond's size, liquidity, and your broker's business model. A $5,000 bond with a 1% markup costs you $50 in hidden fees. Online brokers often have lower markups than full-service brokers, but you're doing the research yourself. Ask your broker directly: "What is your markup on this bond?" A good broker will tell you.

You may also encounter accrued interest, which is interest that has accumulated since the last coupon payment date. When you buy a bond between coupon dates, you pay the seller the accrued interest they've earned. You'll get that money back when you receive your first coupon payment. This is standard and not a hidden cost — it's just how bond trading works.

Place your order and confirm the trade

Once you've found a bond you want, tell your broker to buy it. If you're on an online platform, you'll enter the quantity (usually one bond at a time, though some platforms let you buy fractional amounts through bond funds) and confirm the order. If you're working with an advisor, they'll execute the trade for you.

Before you confirm, make sure you understand:

  • The bond's CUSIP number (a unique identifier)
  • The coupon rate and maturity date
  • The price you're paying and the markup
  • The settlement date (usually 2 to 3 business days after the trade)
  • When you'll receive your first coupon payment

Once you confirm, the trade is binding. Your broker will send you a confirmation statement showing all the details. Keep this for your records. The bond will settle in 2 to 3 business days, meaning the money leaves your account and the bond is registered in your name.

Receive coupon payments and hold until maturity

After your bond settles, you own it. The issuer will send you coupon payments (interest) on the dates specified — usually twice a year, though some bonds pay annually or quarterly. Most brokers let you set up automatic reinvestment, where coupon payments are automatically used to buy more bonds or deposited into your account.

You can hold the bond until maturity, at which point the issuer will return your principal. Or you can sell it before maturity if you need the money. If you sell early, the price you get depends on interest rates and the bond's credit quality — if rates have risen since you bought it, the bond will be worth less. If rates have fallen, it will be worth more.

Keep track of your bonds for tax purposes. The interest you receive is subject to federal income tax (and state income tax in most states), but municipal bonds are exempt from federal tax and often from state tax if they're issued in your home state. Your broker will send you a 1099-INT form at tax time showing the interest you received.

Frequently Asked Questions

What's the minimum amount I need to invest in municipal bonds?

Most municipal bonds have a minimum purchase of $5,000 per bond. Some brokers allow smaller purchases through municipal bond funds or by buying fractional shares. If you want to start with less than $5,000, ask your broker about bond funds or ETFs that hold municipal bonds — these let you invest any amount and spread your money across many bonds.

Can I buy municipal bonds directly from the city or state?

Some states and cities sell bonds directly to the public through programs like Treasury Direct (for U.S. Treasury bonds) or direct offerings, but this is rare for municipal bonds. Most municipal bonds are sold through brokers. Your best option is to contact your state's bond issuer or finance office to ask if they offer direct sales, but you'll likely be directed to a broker.

What happens if the city or state that issued my bond goes bankrupt?

Municipal bond defaults are rare, but they do happen. If an issuer defaults, you may not receive your full principal or interest payments. This is why credit ratings matter — they reflect the risk of default. Bonds rated A or higher have very low default rates. If you're concerned about a specific issuer, check its credit rating and financial reports before you buy.

Should I buy individual bonds or a municipal bond fund?

Individual bonds are better if you want predictable income and plan to hold until maturity — you know exactly when you'll get your money back and how much interest you'll receive. Bond funds are better if you want diversification, lower minimums, or professional management. Funds charge annual fees (typically 0.2% to 1% per year), but they spread your money across many bonds and handle reinvestment automatically.

How do I know if a municipal bond is a good deal?

Compare the yield to maturity (YTM) to other bonds with similar maturity dates and credit ratings. If a bond's YTM is significantly higher than comparable bonds, ask why — it may be riskier or less liquid. Also ask your broker what the markup is. A good deal is a bond with a reasonable yield, a solid credit rating, and a markup under 1%.
