How to buy municipal bonds

You buy municipal bonds through a broker — either a traditional brokerage firm, an online broker, or directly from some issuers. You open an account, deposit money, search for bonds that match what you want to hold, and place an order. The bond issuer (a city, county, or state agency) receives the money, and you receive periodic interest payments plus your principal back when the bond matures. Most individual investors buy bonds through a brokerage because brokers have access to a wider selection and handle the paperwork.

The process is simpler than stock trading because you are not trying to time a price move — you are buying something you plan to hold to maturity. That said, you do need to understand what you are buying: the issuer's creditworthiness, the interest rate you will receive, when your money comes back, and whether the bond is callable (meaning the issuer can pay it off early).

Key Takeaways

  • You need a brokerage account to buy municipal bonds; online brokers like Fidelity, Charles Schwab, and E*TRADE all offer them, and many charge no commission on bond trades.
  • Municipal bonds typically pay interest every six months, and you get your full principal back on the maturity date if you hold the bond to the end.
  • The bond's rating (from agencies like Moody's or S&P) tells you the risk that the issuer will fail to pay; higher-rated bonds are safer but pay less interest.
  • You can buy individual bonds or bond funds; individual bonds give you certainty about when you get your money back, while funds offer easier diversification but fluctuate in price.
  • Tax-exempt status means you owe no federal income tax on the interest, and sometimes no state income tax either, which makes the actual return higher than the stated rate.

Opening a brokerage account

Start by choosing a broker. Most major online brokers — Fidelity, Charles Schwab, E*TRADE, TD Ameritrade, and Vanguard — offer municipal bond trading with no commission. Some brokers specialize in bonds and may have better selection or research tools. You can also use a traditional full-service broker, though they typically charge a markup on each bond you buy.

The account opening process is the same as for stocks: you provide your name, address, Social Security number, and employment information. The broker will ask what type of account you want — a regular taxable account, an IRA, or a 401(k) if you are self-employed. For municipal bonds, a regular taxable account makes the most sense because the tax-exempt status is the main benefit, and IRAs already shelter you from taxes anyway.

Once your account is open and you have deposited money, you are ready to search for bonds. Most brokers have a bond screener where you can filter by issuer type (city, county, state), maturity date, credit rating, and yield. Start by looking at bonds rated A or higher — these are considered investment-grade and carry low default risk.

Understanding bond ratings and credit quality

Credit ratings are letter grades that tell you how likely an issuer is to pay you back on time. The three major rating agencies are Moody's, Standard & Poor's (S&P), and Fitch. Moody's uses Aaa, Aa, A, Baa, and lower grades; S&P uses AAA, AA, A, BBB, and lower. The higher the rating, the safer the bond — but also the lower the interest rate it pays.

Bonds rated BBB or higher (Moody's: Baa or higher) are considered investment-grade. Anything below that is speculative and carries real default risk. For most individual investors, sticking to A-rated bonds or better is the right choice. You can find the rating on your broker's bond page, or look it up free on Moody's or S&P's websites.

A bond's rating can change if the issuer's finances worsen. If you own a bond and it gets downgraded, the bond's market price will fall — though if you hold it to maturity, you still get your full principal back. This is why holding to maturity matters: you are not betting on the price, you are betting the issuer stays solvent long enough to pay you.

Choosing between individual bonds and bond funds

An individual bond is a single debt security issued by one city or state. When you buy one, you know exactly how much interest you will receive, when you will receive it (usually twice a year), and when you get your principal back (the maturity date). If you hold it to maturity and the issuer does not default, you have no surprises.

A municipal bond fund is a pool of many bonds managed by a fund company. You buy shares in the fund, not individual bonds. The fund pays you dividends (usually monthly) from the interest it collects, but the share price fluctuates daily based on interest rates and the credit quality of the bonds inside. If you need your money before the fund's bonds mature, you sell your shares at whatever price they are trading for that day — which could be more or less than you paid.

Individual bonds are better if you want certainty and plan to hold for years. Bond funds are better if you want monthly income, want to own many bonds without picking each one, or might need to sell before maturity. Most beginners should start with individual bonds because they are easier to understand and you control the outcome.

Placing your first bond order

Once you have found a bond you want to buy, your broker will show you the price and yield. The price is what you pay per $1,000 of face value — it might be $980 or $1,020, depending on interest rates and credit conditions. The yield is the annual interest rate you will receive, stated as a percentage.

Before you buy, check three things: the maturity date (when you get your money back), the coupon rate (the interest rate), and whether the bond is callable. A callable bond means the issuer can pay it off early if interest rates fall — which is bad for you because you lose the high interest rate and have to reinvest at lower rates. Your broker's bond page will tell you if a bond is callable and when.

To place an order, you enter the quantity (usually in $1,000 increments), review the total cost, and submit. Most bond trades settle in one or two business days, meaning the money leaves your account and the bond appears in your portfolio. You will then receive interest payments on the schedule the bond specifies — usually twice a year on fixed dates.

Tax benefits and how they affect your return

The main reason to buy municipal bonds is the tax exemption. Interest from municipal bonds is not subject to federal income tax. If you buy a bond issued in your home state, the interest is usually exempt from state income tax too. This means your actual after-tax return is higher than the stated yield.

For example, if a municipal bond pays 3% and you are in the 24% federal tax bracket, the equivalent taxable yield is about 3.95% — meaning you would need a taxable bond paying 3.95% to come out even after taxes. The higher your tax bracket, the more valuable the tax exemption becomes. This is why municipal bonds make the most sense for people in higher tax brackets.

You do not have to do anything special to get the tax benefit — it is automatic. When you file your taxes, you do not report the municipal bond interest as income. Your broker will send you a 1099-INT form showing the interest you received, but you leave that line blank on your tax return.

What happens when your bond matures

On the maturity date, the issuer sends you your principal — the full face value of the bond, usually $1,000 per bond. This happens automatically; your broker receives the money and deposits it into your account. You will see it show up as a credit a day or two after the maturity date.

At that point, you have a choice: reinvest the money in another bond, move it to a savings account, or use it for something else. Many investors reinvest because they want to keep the steady income stream. If interest rates have risen since you bought your first bond, you may be able to find a new bond paying a higher rate. If rates have fallen, new bonds will pay less, but that is the market — you cannot control it.

If you own a callable bond and the issuer calls it early, the same thing happens: you get your principal back before the stated maturity date. This is usually bad news because it means interest rates have fallen and you will have to reinvest at lower rates.

Common mistakes to avoid

The biggest mistake is buying too many bonds at once without understanding each one. Start with one or two bonds from issuers you recognize — your state, a major city, or a well-known agency. Read the bond's official statement (your broker can provide this) to understand what the money is for and whether the issuer has a solid track record of paying its debts.

Another mistake is chasing yield. A bond that pays 5% when similar bonds pay 3% is usually paying more because it is riskier — either the issuer has weaker finances or the bond is callable. The extra interest is not information programs; it is compensation for taking on extra risk. Stick to investment-grade bonds unless you have a specific reason to take on more risk.

A third mistake is selling before maturity because you think interest rates will fall and the bond price will rise. You might be right, but you might be wrong — and if you are wrong, you lock in a loss. Unless you have a genuine need for the money, hold the bond to maturity and collect your interest payments.

Frequently Asked Questions

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

Most municipal bonds have a face value of $5,000 or $10,000, though some brokers allow you to buy in $1,000 increments. You can start with one bond, so $1,000 to $5,000 is enough to begin. Some bond funds have lower minimums — sometimes $1,000 or even $100 — if you want to start smaller.

What if the city or state that issued my bond runs out of money?

If an issuer defaults, you may not get all your money back. This is rare for investment-grade bonds but does happen. That is why credit ratings matter: a bond rated A or higher has a very low historical default rate. If you are worried about a specific issuer, check its rating before you buy.

Can I sell my bond before it matures?

Yes, you can sell any bond on the secondary market through your broker. The price you get depends on current interest rates and the bond's credit quality. If rates have risen since you bought the bond, you will get less than you paid. If rates have fallen, you will get more. This is why holding to maturity removes the guessing game.

Are municipal bonds better than savings accounts or CDs?

Municipal bonds typically pay more interest than savings accounts or CDs, and the interest is tax-free. However, bonds carry credit risk (the issuer might default) and interest-rate risk (the price fluctuates if you sell before maturity). Savings accounts and CDs are insured by the FDIC and have no price risk. Choose based on your time horizon and risk tolerance.

How do I know if a municipal bond is right for my tax situation?

Municipal bonds make the most sense if you are in a higher tax bracket — generally 24% or higher. If you are in a lower bracket, the tax benefit is smaller and a taxable bond might pay more after taxes. You can calculate the equivalent taxable yield using your broker's tools, or ask a tax professional whether municipal bonds make sense for you.
