You can buy municipal bonds through a broker, directly from your state or municipality, or through a fund — each route has different costs and minimum investments

Municipal bonds are sold through four main channels: a full-service brokerage firm, a discount broker, directly from the issuer, or as part of a mutual fund or exchange-traded fund (ETF). Which one makes sense depends on how much you want to invest, whether you want individual bonds or a diversified portfolio, and how much you want to pay in fees. There is no single "best" place — the right choice depends on your situation.

Before you buy anywhere, understand that municipal bonds are not traded on a central exchange the way stocks are. The municipal bond market is decentralized, which means prices and availability vary by seller. This also means you should compare offerings across at least two sources before committing money.

Key Takeaways

  • Full-service brokers offer guidance but charge markups on individual bonds, typically making them most useful if you are buying a large portfolio or need advice on tax strategy.
  • Discount brokers like Fidelity, Charles Schwab, and E*TRADE have lower markups and are the standard choice for individual investors buying a handful of bonds.
  • Buying directly from your state or municipality through a bond offering is possible but requires you to act during the offering period and usually involves a minimum investment.
  • Municipal bond funds and ETFs let you own a diversified portfolio with a small initial investment, but you pay an annual fee and give up the option to hold bonds to maturity.
  • The secondary market — where existing bonds are resold — is where most individual investors actually buy, and prices there vary significantly by broker.

Discount Brokers: The Most Common Route for Individual Investors

Most individual investors buy municipal bonds through a discount broker. The major platforms — Fidelity, Charles Schwab, E*TRADE, and Merrill Edge — all offer municipal bond trading. You open an account, fund it, and search their municipal bond inventory. The process is straightforward and the markups are lower than full-service firms, typically in the range of $5 to $10 per $1,000 bond, though this varies by bond type and market conditions.

Discount brokers maintain an inventory of bonds they own or can access. When you buy, you are usually buying from their inventory or from another dealer's inventory through their network. The markup is built into the price you see — you do not pay a separate commission. This means the price shown is the actual price you pay.

The trade-off is that you get no advice. You are responsible for researching the bond, understanding the issuer's credit quality, and deciding whether the yield makes sense for your goals. If you are comfortable doing that research yourself or using third-party resources like Morningstar or the Municipal Securities Rulemaking Board (MSRB) database, a discount broker is usually the cheapest option.

Full-Service Brokers: When You Want Guidance

A full-service brokerage firm like Merrill Lynch, Morgan Stanley, or UBS will sell you municipal bonds and provide advice on which ones fit your portfolio and tax situation. This is useful if you are building a large portfolio, have complex tax considerations, or want someone to explain the risks and trade-offs in person.

The cost is higher. Full-service brokers typically charge markups of $10 to $25 per $1,000 bond, sometimes more. On a $10,000 bond, that could mean paying $100 to $250 more than you would at a discount broker. Over a portfolio of several bonds, this adds up quickly. You are paying for the advice and the relationship, not just for access to the bonds.

Full-service brokers also have minimum account sizes, often $100,000 or more, and may require you to maintain a relationship with a specific advisor. This route makes sense if you have significant assets to invest and want ongoing portfolio management, but it is expensive for smaller purchases.

Buying Directly From the Issuer During a New Offering

When a state, city, or other municipality first issues bonds, they hold an offering period during which you can buy directly. During this window, you avoid the secondary market markup entirely. You buy at the offering price, which is set by the underwriter.

The catch is timing and minimum investment. You have to know about the offering, which requires monitoring your state or municipality's finance department website or signing up for alerts. Most offerings have a minimum purchase of $5,000 to $25,000. Once the offering period closes, those bonds move to the secondary market, and you can no longer buy them at the original price.

To find upcoming offerings in your state, visit your state treasurer's website or your municipality's finance office. Some states publish a calendar of bond offerings. You can also ask a broker to notify you when bonds from your area are being issued.

Municipal Bond Funds and ETFs: Diversification Without Picking Individual Bonds

If you do not want to research individual bonds or do not have enough money to build a diversified portfolio of individual bonds, a municipal bond fund or ETF is an alternative. These are investment funds that hold dozens or hundreds of municipal bonds. You buy shares in the fund, not the bonds themselves.

The advantage is instant diversification and low entry cost — you can start with as little as $1,000 or even less with some ETFs. The fund manager handles the research and rebalancing. You can buy and sell fund shares through any broker just like stocks.

The disadvantage is that you pay an annual expense ratio — typically 0.2% to 0.5% per year for a passively managed fund, higher for actively managed funds. You also lose the option to hold a bond to maturity and collect all the interest. If interest rates rise, the fund's share price falls, and you could sell at a loss. With an individual bond held to maturity, you get all your principal back regardless of rate changes.

Municipal bond funds are useful for investors who want exposure to municipal bonds but prefer not to manage individual securities. They are also useful if you want to invest a small amount regularly over time.

The Secondary Market: Where Most Bonds Actually Trade

Most municipal bonds you buy are not new issues — they are existing bonds being resold by other investors. This is called the secondary market. Prices in the secondary market fluctuate based on interest rates, the issuer's credit quality, and supply and demand.

The secondary market is where discount brokers source most of their inventory. When you search for bonds on Fidelity or Schwab, you are usually looking at bonds available in the secondary market. Prices vary by dealer, which is why comparing across brokers before you buy matters.

The MSRB publishes a database of municipal bond trades at emma.msrb.org. You can search for specific bonds and see recent trade prices. This helps you understand whether the price a broker is quoting you is reasonable. If a bond traded at 98 yesterday and a broker is quoting it at 102 today, you can ask why or shop elsewhere.

What to Compare Before You Buy

Regardless of where you buy, compare these factors across at least two sources:

  • Price: The dollar amount you pay per bond. Use the MSRB database to see recent trades and understand whether the quote is competitive.
  • Yield to maturity: The annual return you will receive if you hold the bond to maturity. Higher is better, but it should reflect the bond's credit quality and time to maturity.
  • Credit rating: The issuer's financial strength, rated by agencies like Moody's or S&P. Higher ratings mean lower risk but typically lower yield.
  • Call features: Whether the issuer can redeem the bond early. This affects your actual return and should be disclosed in the offering documents.
  • Markup or fee: The cost you are paying to buy. At a discount broker this is built into the price; at a full-service broker it may be stated separately.

Frequently Asked Questions

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

Only during a new offering, and only if you meet the minimum investment. Once the offering closes, the bonds move to the secondary market and you need a broker to buy them. Some municipalities offer direct purchase programs for their own bonds, but these are rare and usually require you to live in that state or municipality.

Why do prices for the same bond differ between brokers?

The municipal bond market is decentralized, so different brokers have different inventory and different markups. One broker may own a bond and quote you a lower price; another may have to source it from a dealer and quote higher. Always compare at least two brokers before buying.

What is the minimum investment to buy municipal bonds?

Individual bonds typically sell in $5,000 increments, though some brokers allow smaller purchases. Municipal bond funds and ETFs have lower minimums, often $1,000 or less. Direct offerings usually have minimums of $5,000 to $25,000.

Do I need a financial advisor to buy municipal bonds?

No. If you are comfortable researching bonds and understanding credit ratings and yield, you can buy through a discount broker on your own. If you want guidance on tax strategy or portfolio construction, a full-service broker or financial advisor can help, but you will pay more for that service.

Should I buy individual bonds or a municipal bond fund?

Individual bonds make sense if you have at least $25,000 to $50,000 to invest and want to hold bonds to maturity. Funds make sense if you have less to invest, prefer not to research individual bonds, or want to add to your position regularly over time. Both are legitimate approaches.
