For individual investors seeking tax-advantaged investment strategies in the fixed-income space, municipal bonds offer an attractive solution. Municipal bonds are debt securities issued by government entities that provide modest returns by way of interest payments over the duration of the bonds. The interest received on a municipal bond is generally exempt from federal tax, and in some cases, state and city tax as well. Individual investors have the ability to purchase municipal bonds individually through the entity issuing the security, or investors may use a pooled investment strategy such as a mutual fund to gain more exposure to multiple municipal bond issues.
While municipal bonds are attractive to investors in higher tax brackets, the securities carry a degree of risk. General obligation bonds, or those backed by the taxing power of the issuing entity, are considered to be safer investments than revenue bonds, or those used to fund specific projects. Because general obligation bonds expose investors to less risk, interest rates paid on these municipal bonds are lower than other debt securities. Revenue bonds have a greater risk of default over time, but they can provide a higher rate of return to investors who are willing to take on that risk. Investing in municipal bond funds allows investors to diversify among general obligation and revenue bonds with the potential for tax-exempt earnings.
Here’s a look at some of the top municipal bond funds for 2018: the American High-Income Municipal Bond Fund (AMHIX), the Nuveen High Yield Municipal Bond Fund I (NHMRX), the Vanguard Intermediate-Term Tax-Exempt Fund Investor Shares (VWITX), the T.
