A sign reading "municipal bonds" sits on top of a hundred- dollar bill.

While stocks get most of the attention in the investment world, municipal bonds can play an important role in a diversified portfolio and may come with attractive tax advantages. Municipal bonds, or munis, are issued by state and local governments to fund various government projects. Unlike most bonds, they are typically exempt from federal income tax, making them an attractive choice for investors in high tax brackets.

Here’s what else you need to know about municipal bonds and a few top funds to consider for your taxable portfolio.

What are municipal bonds and how do they work?

Municipal bonds are issued by state and local governments to raise money for public projects such as schools and roads. General obligation bonds are used for projects that aren’t likely to generate revenue, while revenue bonds are paid back with revenue from specific projects, such as a toll road or an entertainment center.

While municipal bonds may not sound like the most exciting investment, they typically come with the benefit of no federal taxes. Plus, in many cases you may not owe state or local taxes either. Because of this tax advantage, a lower yield on a municipal bond may actually be more attractive than a higher-yielding taxable bond once you adjust for the tax savings.

Here’s how it works: Imagine you’re a high earner with a federal income tax rate of 37 percent and a state tax rate of 7 percent. You’re considering a municipal bond with a yield of 3 percent and a taxable bond with a yield of 4 percent.

Tax-equivalent yield = Interest rate / (1 – tax rate)

You’ll see that the municipal bond has a tax-equivalent yield of almost 4.8 percent based on just the federal tax savings, and the tax-equivalent yield rises to 5.4 percent when you account for the additional state tax savings, both of which outpace the 4 percent yield on the taxable bond.

Investors in high tax brackets benefit most from the tax advantages of municipal bonds, but even if you’re in a lower tax bracket, munis may be a good fit for your portfolio. In general, municipal bonds come with a low risk of default and have less volatility than riskier corporate bonds or stocks.

While you can invest in individual municipal bonds, it’s easier to invest in a municipal bond fund. Investing in a fund means you don’t have to research all the individual investments and you’ll get the benefits (such as reduced risk) of holding a diversified portfolio of municipal bonds. Here are some top funds to consider.

Bottom line

While municipal bonds aren’t likely to generate returns as high as other investments such as stocks, they can provide tax benefits to your portfolio, particularly if you’re in a high income-tax bracket. Because of these tax advantages, it makes sense to hold municipal bond funds in taxable accounts only, not retirement accounts such as 401(k)s and IRAs, which already have tax advantages.
