You buy municipal bonds through a broker, your bank, or directly from the issuer

Municipal bonds are not sold in one place the way stocks are. Instead, you purchase them through a financial intermediary — most commonly a brokerage firm, a bank, or occasionally straight from the municipality or a bond underwriter. The route you choose affects the price you pay, the fees involved, and how much help you get in understanding what you're buying.

The bond itself is issued by a city, county, state, or other public entity to raise money for infrastructure like schools, roads, or water systems. Once issued, these bonds trade in what's called the secondary market, where prices fluctuate based on interest rates and the issuer's credit quality. Most individual buyers never touch the primary market (the initial sale); they buy existing bonds through a broker or bank instead.

Key Takeaways

  • Full-service brokerages and discount brokers both sell municipal bonds, but full-service firms typically charge higher markups while offering more guidance on selection.
  • Banks can sell you municipal bonds, though their inventory is often limited and markups may be higher than at a dedicated brokerage.
  • Direct purchase from the issuer or through a bond underwriter is possible but rare for individual investors and usually requires larger minimum investments.
  • Online brokerages have made municipal bond trading cheaper and more transparent, though you need to do your own research on which bonds fit your situation.
  • The price you pay includes a markup or commission that varies widely depending on the seller and the specific bond, so comparing quotes is worth the effort.

Full-Service Brokerages and What They Charge

A full-service brokerage like Merrill Lynch, Morgan Stanley, or UBS has a municipal bond desk with brokers who can discuss your goals, suggest bonds that match your tax situation, and handle the transaction. These firms typically hold inventory — they own bonds and sell them to you — which means they make money on the markup, the difference between what they paid and what they charge you.

The markup on municipal bonds is not always transparent. You may see a price quoted, but the markup is often embedded in that price rather than shown as a separate line item. Full-service firms justify higher markups by pointing to research, advice, and the convenience of dealing with a person. If you have a substantial portfolio or complex tax considerations, that guidance can be worth the cost. If you're buying a straightforward bond, you're paying for service you may not need.

Minimums at full-service firms vary, but many expect you to buy at least $5,000 to $25,000 worth of bonds in a single transaction. Some will go lower if you're an existing customer with other assets at the firm.

Discount Brokerages and Online Platforms

Discount brokerages like Fidelity, Charles Schwab, E*TRADE, and TD Ameritrade offer municipal bonds with lower markups and more price transparency than full-service firms. Many show you the markup explicitly, or at least let you see the bid-ask spread — the difference between what buyers are willing to pay and what sellers are asking. This transparency makes it easier to shop around and understand what you're actually paying.

These platforms typically have larger inventories than banks and more bonds available for purchase on any given day. You do your own research using the tools and data they provide, which means you need to be comfortable reading bond ratings, yield information, and maturity dates. The tradeoff is lower costs in exchange for less hand-holding.

Minimums are often lower at discount brokerages — sometimes as little as $1,000 per bond — though some bonds in their inventory may have higher minimums set by the issuer or underwriter. Account minimums to open a brokerage account are typically zero or very low.

Banks and Credit Unions

Your bank or credit union can sell you municipal bonds, and this route works well if you want to keep everything in one place and prefer talking to someone you know. However, banks typically have a smaller selection than brokerages, and their markups tend to be higher because they're not primarily in the bond business.

A bank's municipal bond desk (if they have one) may focus on bonds issued locally or by the state where the bank operates. This can be an advantage if you want bonds from your own community, but it limits your options if you're looking for specific credit quality or yield characteristics. Banks also may not offer the same research tools or price transparency as a brokerage.

Credit unions sometimes offer municipal bonds to members, though availability varies widely. Ask your institution what they have in stock and what their markup structure is before committing.

Direct Purchase and Bond Underwriters

When a municipality first issues bonds, an underwriter — usually an investment bank — handles the sale. In theory, you can buy directly from the underwriter during the initial offering period, sometimes called the primary market. In practice, this is rare for individual investors. Underwriters typically work with institutional buyers and financial advisors, and minimums are often $25,000 or higher.

Some municipalities maintain their own bond sales programs or work with financial advisors to sell bonds directly to residents. These programs are uncommon and usually limited to bonds issued by that specific entity. If you live in a state or municipality that runs such a program, your local government website or finance office can tell you whether it exists and how to participate.

The advantage of buying during the primary offering is that you know the exact terms and there's no secondary market markup — you're buying at the official offering price. The disadvantage is limited selection and high minimums, which makes this route impractical for most individual investors building a diversified portfolio.

How to Compare Prices Across Sellers

Municipal bond prices are not standardized across sellers the way stock prices are. The same bond can be quoted at different prices by different brokers because each one has its own inventory and markup structure. Getting multiple quotes before you buy is the only way to know whether you're getting a fair price.

Call or log into your brokerage account and ask for a quote on a specific bond — you'll need the issuer name, coupon rate, and maturity date. Write down the price and the yield-to-maturity (YTM), which tells you the actual return you'll earn if you hold the bond to maturity. Then call or check another broker and ask for the same bond. A difference of even 0.5% in price can mean hundreds of dollars over the life of the bond.

Some online brokerages show you multiple bonds at once with their markups visible, which makes comparison easier. Others require you to call for a quote. The effort to compare is worth it, especially on larger purchases.

What Happens After You Buy

Once you own a municipal bond, you hold it in your brokerage or bank account. You receive interest payments (called coupons) on a set schedule — usually twice a year — and those payments are deposited into your account. If you sell before maturity, you go back to your broker and they find a buyer in the secondary market. If you hold to maturity, the issuer pays you back the full face value.

Your broker or bank sends you statements showing your holdings, their current market value, and the income you've earned. You're responsible for reporting the interest income on your tax return, though the tax-free status of most municipal bond interest means you typically don't owe federal tax on it (and often state tax too, depending on where the bond was issued and where you live).

Frequently Asked Questions

Can I buy municipal bonds directly from the city or county that issued them?

Rarely. Most municipalities do not maintain a direct sales program for individual investors. Your best option is to ask your city or county finance office whether they offer one, but expect the answer to be no. Going through a broker or bank is the standard route.

What's the difference between the bid and ask price I see quoted?

The bid is what a buyer will pay for the bond right now; the ask is what a seller is asking. The difference between them is the spread, and it's part of how brokers make money. A tighter spread (smaller difference) is better for you. On municipal bonds, spreads vary widely depending on how actively the bond trades.

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

Minimums vary by broker and by bond. Many discount brokerages let you start with $1,000 per bond, while full-service firms may require $5,000 to $25,000. Some individual bonds have their own minimums set by the issuer. Check with your broker about their requirements before you open an account.

Is it cheaper to buy municipal bonds online or through a person?

Online and discount brokerages typically charge lower markups than full-service brokers or banks. However, the specific bond you want and the size of your purchase matter. Get quotes from multiple sources — online and traditional — for the same bond before deciding.

What if I want to sell a municipal bond before it matures?

Call your broker and ask for a quote on selling. They'll find a buyer in the secondary market and execute the sale. The price you get depends on current interest rates and the bond's credit quality. You may get more or less than you paid, depending on market conditions.
