You can buy municipal bonds through a broker, directly from your state or municipality, or through a fund — each route has different minimums and costs
Municipal bonds are sold through three main channels: a brokerage account (online or traditional), directly from the issuer or a municipal bond platform, or as part of a mutual fund or exchange-traded fund. The route you choose depends on how much money you have to invest, whether you want to pick individual bonds or own a diversified pool, and how much trading you plan to do. Most individual investors start with a brokerage account because the minimum investment is usually $5,000 per bond, and you can buy and sell without restriction.
Before you buy, you need to understand that municipal bonds are less liquid than stocks — meaning it can take time to sell one if you need cash before maturity. You also need to read the official statement for each bond, which discloses the issuer's finances and the bond's terms. This is not optional research; it is how you know whether the bond will actually pay you back.
Key Takeaways
- Municipal bonds are typically sold in $5,000 increments through brokerages, though some platforms and direct offerings have lower minimums.
- You will need to read the official statement for each bond before buying, which contains the issuer's financial information and the bond's payment schedule.
- Brokerage accounts let you buy individual bonds; mutual funds and ETFs let you own many bonds at once but charge annual fees.
- Municipal bonds are harder to sell quickly than stocks, so only invest money you do not plan to need before the bond matures.
- Tax-exempt status applies at the federal level for all municipal bonds, but state and local tax treatment varies by where you live and where the bond was issued.
Opening a brokerage account and finding bonds to buy
Start by opening an account at a brokerage that offers municipal bonds. Major firms like Fidelity, Charles Schwab, E-Trade, and Vanguard all carry them. You will need to provide your Social Security number, proof of address, and banking information for deposits and withdrawals. The account setup takes a few days.
Once your account is open, search the brokerage's bond inventory by state, maturity date, credit rating, and yield. Most brokerages let you filter by tax-exempt status and whether you want general obligation bonds (backed by the issuer's tax revenue) or revenue bonds (backed by a specific project's income). Start by looking at bonds rated A or higher by Moody's or Standard & Poor's — these are considered investment-grade and carry lower default risk.
When you find a bond you are interested in, the brokerage will show you the offering price, the coupon rate (the interest rate you will receive), the maturity date, and the yield to maturity (what you will actually earn if you hold it to the end). Read the official statement before you commit money. This document is usually available as a PDF link in the bond listing or on the issuer's website.
Understanding the official statement and bond terms
The official statement is a legal document that describes the bond issuer, the project or purpose the bond finances, the issuer's financial condition, and the bond's repayment terms. It is typically 50 to 100 pages. You do not need to read every word, but you do need to understand the issuer's debt level, revenue sources, and any risks flagged in the document.
Pay attention to the maturity date — this is when you get your principal back. If you buy a 20-year bond, you are committing that money for 20 years. Check whether the bond is callable, meaning the issuer can pay it off early if interest rates drop. A callable bond limits your upside if rates fall, because the issuer will refinance and you will lose the higher yield.
Look at the coupon payment schedule. Most municipal bonds pay interest twice a year, in May and November, or in January and July. Some pay monthly. Confirm that the payment dates work for your cash flow needs. Also check the credit rating and any recent rating changes — a downgrade signals financial trouble at the issuer.
Buying individual bonds versus bond funds
| Individual Bonds | Municipal Bond Funds (Mutual Funds or ETFs) |
|---|---|
| Minimum investment: Usually $5,000 per bond | Minimum investment: Often $1,000 or less; some ETFs trade at share price |
| You know exactly what you own and when you get paid | You own a slice of many bonds; the fund manager handles buying and selling |
| You can hold to maturity and avoid market price swings | Price fluctuates daily; you can sell anytime but may take a loss |
| No annual fee, but you pay a markup when you buy and a markdown when you sell | Annual expense ratio (typically 0.2% to 0.5% per year) charged automatically |
| Harder to sell before maturity; may take days or weeks | Easy to sell; mutual funds settle in one business day, ETFs in seconds |
| You choose which bonds to buy based on your goals | The fund manager chooses; you get diversification automatically |
Individual bonds make sense if you have at least $25,000 to $50,000 to invest, you want to hold bonds until they mature, and you are willing to spend time researching each one. You will know exactly what you own and when you get paid. The trade-off is that selling before maturity can be slow and expensive.
Bond funds make sense if you have less money, want instant diversification, or think you might need to access your cash before the bonds mature. The fund manager buys and sells bonds on your behalf, so you do not have to research individual offerings. The cost is an annual expense ratio that comes out of your returns. For municipal bond funds, this is typically between 0.2% and 0.5% per year.
Placing your order and understanding costs
When you are ready to buy, enter the bond's CUSIP number (a unique identifier) into your brokerage's order form, specify the quantity and price, and submit. Most municipal bond orders settle in two business days, meaning the money leaves your account and the bond appears in your portfolio two days after you buy.
You will pay a markup on the purchase price — this is how the broker makes money. The markup is usually between 0.5% and 2% of the bond's value, though it is often hidden in the price rather than shown as a separate line item. Ask your broker what the markup is before you buy. When you sell before maturity, you will pay a markdown (the reverse of a markup), which can be larger than the markup you paid to buy.
If you hold the bond to maturity, you do not pay a selling cost — you simply receive your principal back on the maturity date. This is one reason holding to maturity is cheaper than trading bonds frequently.
Tax implications and state-specific considerations
Municipal bond interest is exempt from federal income tax. This is the main reason people buy them — a 4% municipal bond yield is worth more than a 4% taxable bond yield because you do not owe federal tax on the 4%.
State and local tax treatment varies. If you buy a bond issued in your home state, the interest is usually exempt from state income tax as well. If you buy a bond issued in another state, you typically owe state income tax on the interest. Some states exempt all municipal bond interest from state tax regardless of where it was issued; others tax it all. Check your state's rules before you buy out-of-state bonds.
When you sell a bond before maturity for more than you paid, you owe federal capital gains tax on the profit. This is true even though the interest itself is tax-exempt. If you sell for less than you paid, you can deduct the loss against other capital gains.
Researching credit quality and avoiding defaults
Municipal bond defaults are rare, but they happen. Before you buy, check the issuer's credit rating from Moody's Investors Service or Standard & Poor's. Ratings range from Aaa/AAA (safest) down to C or D (highest risk). Bonds rated Baa3/BBB or higher are considered investment-grade; anything below that is speculative and carries real default risk.
Read recent news about the issuer. If a city or state is facing budget cuts, pension crises, or declining population, these are warning signs. Check the issuer's most recent financial reports, which are usually posted on the Municipal Securities Rulemaking Board's EMMA database (emma.msrb.org). This free database contains official statements, financial reports, and rating changes for most municipal bonds.
Diversify across issuers and bond types. Do not put all your money into bonds from one city or state, even if they offer high yields. A diversified portfolio of investment-grade bonds from different regions and sectors reduces your risk.
Frequently Asked Questions
What is the minimum amount I need to invest in municipal bonds?
Individual bonds typically have a $5,000 minimum per bond. If you want to buy multiple bonds, you need $5,000 for each one. Municipal bond mutual funds and ETFs often have lower minimums — sometimes $1,000 or less for mutual funds, and just the share price for ETFs, which can be $50 to $100.
Can I buy municipal bonds directly from the city or state?
Some issuers sell bonds directly to the public through platforms like TreasuryDirect or their own websites, but this is uncommon. Most individual investors buy through a brokerage. Direct purchases, when available, may have lower minimums or no markup, but you will have fewer bonds to choose from.
What happens if the city or state that issued my bond goes bankrupt?
Municipal bankruptcies are rare. When they occur, bondholders are typically paid before other creditors, though sometimes at a reduced amount. The issuer's credit rating and financial reports help you assess this risk before you buy. Sticking to investment-grade bonds (A rating or higher) significantly reduces this risk.
Should I buy bonds maturing in 5 years or 30 years?
Shorter maturity bonds (5 to 10 years) pay lower interest rates but are less sensitive to interest rate changes. Longer maturity bonds (20 to 30 years) pay higher rates but can lose value if interest rates rise. Choose based on how long you can lock up your money and how much interest rate risk you are comfortable with.
Can I sell my municipal bond before it matures?
Yes, but it is slower and more expensive than selling a stock. You can sell through your brokerage, but the bond will be priced based on current interest rates and the issuer's credit quality. If rates have risen since you bought, your bond will be worth less. Expect the sale to take several days and to pay a markdown.
