You can buy municipal bonds through a broker, directly from your state or municipality, or through a bond fund
Municipal bonds are sold in three main ways: through a brokerage account (the most common route for individual investors), directly from the issuer or a municipal bond platform, or as part of a mutual fund or exchange-traded fund. Each route has different costs, minimum investments, and levels of convenience. Most individual buyers use a broker because they offer a wide selection, handle the paperwork, and let you buy and sell on the secondary market — meaning you can exit before maturity if you need the money.
The choice depends on how much you want to invest, whether you plan to hold until maturity, and how much research you want to do yourself. A broker gives you flexibility but may charge transaction fees. Direct purchase from an issuer cuts fees but limits your options to that specific bond. Bond funds require no picking and choosing but charge annual management fees.
Key Takeaways
- Brokerages like Fidelity, Charles Schwab, and Vanguard let you buy individual municipal bonds and bond funds, with access to thousands of issues across states.
- Direct purchase from your state or municipality through platforms like TreasuryDirect or your state's bond office eliminates middleman fees but offers fewer choices.
- Municipal bond funds and ETFs spread your money across many bonds, reducing risk from a single issuer defaulting, but charge annual fees of 0.2% to 1% or more.
- The secondary market (buying bonds already issued) is where most individual transactions happen; brokers handle these sales and may charge per-bond markups.
- Minimum investments range from $1,000 to $5,000 for individual bonds and as little as $1 for some bond funds, depending on the seller.
Buying through a full-service or discount brokerage
A brokerage account is the standard way most individual investors buy municipal bonds. Firms like Fidelity, Charles Schwab, E*TRADE, and Vanguard all offer municipal bond trading. You open an account, fund it, and search their bond inventory — which typically includes thousands of issues from across the country. The broker handles settlement (the paperwork and money transfer), holds the bonds in your account, and sends you interest payments.
Brokerages charge in different ways. Some charge a flat fee per bond transaction (often $0 to $10 for municipal bonds). Others use a markup — they buy the bond wholesale and sell it to you at a higher price, pocketing the difference. The markup is usually built into the price you see, so you do not see a separate line item. Markups on municipal bonds typically range from 0.5% to 2% of the purchase price, though this varies by bond type and market conditions.
The main advantage of a brokerage is access to the secondary market. You can buy bonds that were issued years ago and are now being resold by other investors. This gives you far more choices than waiting for new issues. You can also sell before maturity if you need cash, though you may take a loss if interest rates have risen since you bought.
Buying directly from the issuer or state programs
Some states and municipalities let you buy their bonds directly without a broker. Your state treasurer's office or a city finance department may sell bonds through a direct purchase program or a dedicated platform. The advantage is lower or no transaction fees — you are buying straight from the source. The disadvantage is that you can only buy that specific issuer's bonds, and your choices are limited to whatever they currently have for sale.
A few states run formal bond purchase programs similar to how the federal government runs TreasuryDirect for U.S. Treasury securities. These are rare and vary widely by state. Your best starting point is your state treasurer's website or your city or county finance office. They can tell you whether direct purchase is an option and what the process is.
Direct purchase makes sense if you want to buy a specific bond from your home state or municipality and hold it to maturity. It does not make sense if you want to compare bonds across issuers or states, or if you think you might need to sell before maturity.
Municipal bond funds and ETFs
A municipal bond fund pools money from many investors and buys a portfolio of bonds. You buy shares of the fund rather than individual bonds. The fund manager handles all the buying, selling, and reinvestment. This approach is simpler if you do not want to research individual bonds or if you have a small amount to invest — many bond funds have no minimum or a minimum of $1,000 or less.
Bond funds come in two types: mutual funds and exchange-traded funds (ETFs). Mutual funds are priced once per day after the market closes. ETFs trade throughout the day like stocks. Both charge annual management fees, typically 0.2% to 1% per year, depending on the fund. Some funds are actively managed (a manager picks the bonds), while others are index funds (they track a benchmark like the Bloomberg Municipal Bond Index).
The trade-off is convenience and diversification against higher ongoing costs. If you hold an individual bond to maturity, you pay the transaction cost once. If you hold a bond fund for 10 years, you pay the annual fee every year. However, a fund spreads your risk across many issuers, so one bond default does not wipe out your investment. Funds also let you reinvest interest automatically and rebalance easily.
Comparing costs across purchase routes
| Purchase Route | Typical Cost | Minimum Investment | Best For |
|---|---|---|---|
| Brokerage (new issue) | 0.5% to 2% markup (built in) | $5,000 | Buying new bonds; access to many issuers |
| Brokerage (secondary market) | $0 to $10 per bond or 0.5% to 2% markup | $5,000 | Buying existing bonds; flexibility to sell early |
| Direct from issuer | $0 to minimal fee | Varies (often $1,000 to $5,000) | Buying one issuer's bonds; holding to maturity |
| Mutual fund | 0.2% to 1% annually | $0 to $1,000 | Small amounts; diversification; hands-off approach |
| ETF | 0.2% to 0.5% annually (typical) | Price of one share (often $50 to $100) | Low-cost diversification; intraday trading |
What to look for when choosing a broker
If you decide to use a brokerage, look for one that offers a large municipal bond inventory, clear pricing, and low or transparent fees. Fidelity, Charles Schwab, and Vanguard are the largest and most widely used by individual investors. They all offer research tools, educational resources, and customer support. Smaller brokers may have lower fees but less inventory and fewer tools.
Before you open an account, check whether the broker charges per-bond fees or uses markups, and ask what their typical markup is on municipal bonds. Some brokers publish this information; others do not. You can also call and ask for a quote on a specific bond you are interested in. Compare quotes from two or three brokers — the difference can be meaningful, especially on larger purchases.
Make sure the broker offers the type of bonds you want. If you are interested in bonds from a specific state or sector (like education or transportation), confirm they have access to those bonds. Also check whether they offer bond funds if you want that option as a backup.
Understanding the secondary market and when to use it
The secondary market is where most municipal bonds change hands after they are first issued. When you buy a bond through a broker, you are usually buying from another investor or a dealer, not from the municipality itself. This is true even if the bond is relatively new.
The secondary market gives you flexibility: you can buy bonds that fit your needs exactly (specific maturity date, credit rating, tax status) rather than waiting for a new issue. You can also sell before maturity if you need cash. However, if interest rates have risen since the bond was issued, you will have to sell at a discount — meaning you get less than you paid. If rates have fallen, you can sell at a premium.
For most individual investors, the secondary market is where you will end up buying. New municipal bond issues are often sold in large blocks to institutional investors first, and individual investors get what is left over. Brokers have access to the secondary market and can show you what is available.
Frequently Asked Questions
Do I need a brokerage account to buy municipal bonds?
No, but it is the easiest way for most people. You can buy directly from your state or municipality if they offer it, or you can buy a municipal bond fund or ETF through a fund company. However, a brokerage account gives you the most choices and the most control over which bonds you own.
What is the difference between buying a new issue and buying on the secondary market?
A new issue is a bond the municipality is selling for the first time. You usually buy it through a broker at the offering price, which includes a markup. On the secondary market, you are buying a bond someone else owns. Prices fluctuate based on interest rates and the bond's credit quality. Both routes go through a broker for individual investors.
Can I buy municipal bonds directly from the U.S. Treasury?
No. The U.S. Treasury sells Treasury bonds, notes, and bills through TreasuryDirect, but municipal bonds are issued by states and cities, not the federal government. You must buy municipal bonds through a broker, directly from the issuer (if they offer it), or through a fund.
Are there hidden fees I should watch out for?
The main hidden cost is the markup — the difference between what the broker paid for the bond and what they sell it to you for. This is usually 0.5% to 2% and is built into the price. Ask your broker to disclose the markup or compare quotes from multiple brokers. Bond funds charge annual fees that are disclosed in the prospectus but easy to overlook.
What is the minimum amount I need to invest?
Individual bonds typically have a $5,000 minimum (one bond is usually $5,000 face value). Some brokers let you buy fractional amounts or smaller denominations. Bond funds and ETFs often have no minimum or a minimum of $1,000 or less. ETFs can be bought one share at a time, which might be $50 to $100 depending on the fund.
