Municipal bonds are bought through a broker, a bank, or directly from your state or local government

You cannot walk into a municipal bond office and hand over money the way you might buy a stock. Instead, you work through a financial intermediary — a brokerage firm, a bank, or occasionally the issuer itself — who holds the bond on your behalf and handles the paperwork. The process takes a few days from decision to settlement, and the cost to you depends on how you buy and who you buy from.

Most individual investors use a brokerage account (online or through a financial advisor) because that gives you access to thousands of bonds and lets you compare prices and yields before committing. Some people buy directly from their state or local government through programs like CollegeInvest or a state bond program, which can lower costs but limits your choices to bonds issued by that state or locality.

Key Takeaways

  • You need a brokerage account, a bank account, or a direct relationship with a government issuer to buy municipal bonds — you cannot purchase them without a financial intermediary.
  • Brokerages charge markups (usually 1 to 3 percent of the bond's price) that are often hidden in the quoted price rather than shown as a separate fee.
  • Municipal bonds typically sell in $5,000 minimum increments, though some brokerages allow smaller purchases through bond funds or ETFs.
  • The secondary market (buying existing bonds from other investors) offers more selection than new issues but may carry higher markups depending on how liquid the bond is.
  • Tax-exempt status means the interest you earn is usually free from federal income tax and often free from state and local tax if you live in the issuing state.

Opening a brokerage account to buy individual bonds

A standard brokerage account — the kind you use to buy stocks — also lets you buy municipal bonds. You can open one at firms like Fidelity, Charles Schwab, E*TRADE, Vanguard, or your local bank's investment division. The account itself is free; you only pay when you buy or sell a bond.

Once your account is open and funded, you search for municipal bonds by issuer, maturity date, yield, or credit rating. The brokerage shows you available bonds and their prices. When you place an order, the bond settles (transfers to your account and the money leaves your account) in three business days. The brokerage collects a markup on the sale — typically 1 to 3 percent of the bond's face value — but this is usually built into the price you see rather than shown as a separate line item.

This route gives you the widest selection because you can access both new bond issues and the secondary market (bonds already issued and held by other investors). It also lets you work with a financial advisor if you want guidance on which bonds fit your goals.

Buying directly from your state or local government

Some states and municipalities run direct-purchase programs that let residents buy their bonds without a broker. Examples include Colorado's CollegeInvest program (for education savings bonds) and various state general obligation bond programs. These programs typically have lower or no markups because you are buying straight from the issuer.

The trade-off is selection: you can only buy bonds issued by that state or locality, and the program may only offer a handful of bond types at any given time. You also have less flexibility on timing — new issues come out on a set schedule, and you cannot easily buy existing bonds from other investors.

To find out whether your state or locality offers direct purchase, contact your state treasurer's office or your city or county finance department. They can tell you whether a program exists, what bonds are currently available, and how to enroll.

Understanding markups and hidden costs

When you buy a municipal bond through a broker, you pay a markup — the difference between what the broker paid for the bond and what you pay. This markup is the broker's profit and covers their operating costs. For individual investors buying one or a few bonds, markups typically range from 1 to 3 percent of the bond's price.

The markup is almost never shown as a separate line on your confirmation. Instead, it is built into the "price" the broker quotes you. If a bond's face value is $5,000 and the broker quotes a price of $5,100, you are paying a $100 markup (2 percent). This is standard practice and legal, but it means you need to compare prices across brokers if you want to shop for the best deal.

Some brokerages offer "no-markup" or "zero-commission" municipal bond trading, but this usually means they are not charging an explicit markup — they may instead earn money by routing your order to a market maker who profits from the spread, or they may charge a flat fee. Read the fine print on your brokerage's website to understand how they make money on bond trades.

Buying new issues versus the secondary market

When a city or state issues new bonds, they are sold through underwriters (usually large investment banks) for a set period. These new issues are called the primary market. You can buy them through your broker during the offering period, and the markup is typically lower because the underwriter is distributing them in bulk.

Once the offering period closes, those bonds trade on the secondary market — between individual investors, institutions, and dealers. Secondary market bonds may have higher markups because they are less liquid (fewer buyers and sellers), and the broker has to work harder to find a match for your order. However, the secondary market gives you access to thousands of bonds with different maturity dates and credit ratings, so you have much more choice.

Most individual investors end up buying from the secondary market because they are buying one or a few bonds at a time, and the selection is vastly larger. New issues are useful if you want to buy a large quantity or if a specific new bond matches your goals exactly.

Minimum investment amounts and bond funds as an alternative

Individual municipal bonds typically have a minimum purchase of $5,000 (one bond at face value). If you have less than $5,000 to invest, or if you want to spread your money across many bonds to reduce risk, a municipal bond fund or exchange-traded fund (ETF) may be a better fit.

Bond funds pool money from many investors and buy a portfolio of bonds. You can buy into a fund with as little as $1,000 or even $100, depending on the fund. The fund manager handles buying and selling individual bonds, and you own a share of the entire portfolio. The trade-off is that you pay an annual management fee (typically 0.2 to 1 percent per year) and you do not own specific bonds — you own a piece of a constantly changing collection.

ETFs work similarly but trade like stocks on an exchange, so you can buy and sell them during market hours. They often have lower fees than actively managed funds because many are index funds that simply track a benchmark like the Bloomberg Municipal Bond Index.

Tax implications and why municipal bonds appeal to high-income earners

The interest you earn on a municipal bond is exempt from federal income tax. If you buy a bond issued by your state or locality, the interest is also usually exempt from state and local income tax. This tax advantage is the main reason people buy municipal bonds, especially if they are in a high federal tax bracket.

For example, if you are in the 24 percent federal tax bracket and earn 4 percent interest on a municipal bond, that is equivalent to earning about 5.3 percent on a taxable bond (because you do not owe federal tax on the 4 percent). The higher your tax bracket, the more valuable the tax exemption becomes.

However, municipal bonds are subject to the Alternative Minimum Tax (AMT) in some cases, and certain bonds (like private activity bonds) may trigger AMT liability. If you are subject to AMT, consult a tax professional before buying municipal bonds. Also, if you sell a bond for more than you paid for it, you owe capital gains tax on the profit — the tax exemption only applies to interest, not to gains.

Steps to buy your first municipal bond

Start by deciding whether you want to work with a broker or buy directly from your state or locality. If you choose a broker, open an account at a firm that offers municipal bonds (most major brokerages do) and fund it with the amount you want to invest.

Next, search for bonds that match your goals: maturity date (when you want your money back), credit rating (how safe the bond is), and yield (the interest rate). Compare prices across brokers if possible — call a few firms and ask for quotes on the same bond to see which one offers the best price.

Once you have found a bond you want, place an order through your brokerage account. The order will settle in three business days, at which point the bond will appear in your account and the money will leave your bank account. You will receive a confirmation statement showing the bond's details, the price you paid, and the markup (if it is disclosed separately).

Frequently Asked Questions

Can I buy municipal bonds if I do not have much money to invest?

Individual bonds require a $5,000 minimum, but municipal bond funds and ETFs let you invest with smaller amounts — sometimes as little as $100. These funds own dozens or hundreds of bonds, so your money is spread across many issuers and you own a small piece of each one.

What happens if I need to sell my bond before it matures?

You can sell a municipal bond on the secondary market through your broker at any time. The price you get depends on interest rates and the bond's credit quality — if rates have risen since you bought it, you will likely sell for less than you paid. The broker will charge a markup on the sale just as they did on the purchase.

How do I know if a municipal bond is safe?

Check the bond's credit rating from agencies like Moody's, Standard & Poor's, or Fitch. Ratings range from AAA (safest) to C (highest risk). Your broker's website will show the rating for any bond you are considering. General obligation bonds (backed by the issuer's tax revenue) are typically safer than revenue bonds (backed by a specific project's income).

Do I owe taxes on the interest from municipal bonds?

No, the interest is exempt from federal income tax. If you buy a bond issued in your home state, the interest is also usually exempt from state and local income tax. However, if you sell the bond for a profit, you owe capital gains tax on that gain.

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

New issues are sold directly by the issuer through underwriters during an offering period, usually with lower markups. Secondary market bonds are existing bonds trading between investors, with more selection but potentially higher markups. Most individual investors buy from the secondary market because the choice is much larger.
