Municipal bonds (also known as munis) are issued by a state or local government. Interest income is typically paid out twice a year and is not subject to federal taxes. When an investor purchases a bond issued from his own state, the income is generally not subject to state income taxes.
However, there are a few good reasons to consider buying out-of-state municipal bonds. The first reason is to consider bond quality. Each muni bond is given a quality rating based on the municipality’s ability to make the regular interest payments to investors and return their principal when the term matures. To make this determination, agencies like Moody’s and S&P evaluate the issuer’s debt structure, financial stability and long-term economic prospects.
Credit Quality
The highest Moody’s rating is Aaa (the lowest is C); a rating of Baa3 or higher is considered investment grade. The highest S&P rating is AAA (the lowest is D), and a rating of BBB or higher is considered investment grade. While it’s a good idea to invest in highly rated bonds, note that their yields are inversely related to their quality. In other words, the lower the rating, the higher the interest income. Just be sure to consider that with that higher yield comes a higher risk of the bond issuer defaulting. In today’s economic landscape, an average credit rating of AA/Aa is considered a good balance of risk and bond yield.
Diversification
Second, if the investor holds a portfolio of municipal bonds, owning some from other states can help diversify his bond portfolio. If the investor’s home state has lower-rated bonds, investing in higher-rated bonds from other states can lower his bond portfolio’s quality risk. On the other hand, if the investor’s home state has highly rated bonds, purchasing bonds from states with lower-rated bonds can increase the amount of income his portfolio pays out. Remember, too, that it’s important to consider both the bond yield (also known as its coupon rate) and its issuing state’s taxes in order to come out ahead.
More Choices
Note that both California and New York are high-tax states, so it’s particularly important to consider the tax situation before buying there. With that said, there are also good reasons to buy bonds in these two states because they offer a range of quality municipal bonds. On the flip side, some states have fewer bond options to choose from and a lower risk profile, leaving resident investors with few options regardless of the state tax benefit. Be aware that the majority of muni bonds are rated lower than AA in Illinois, Pennsylvania, and New Jersey.
Tax Considerations
There are seven states that do not impose state income taxes: Alaska, Florida, Nevada, South Dakota, Tennessee, Texas, Washington, and Wyoming. New Hampshire recently phased out its tax on investment and interest income. If a muni bond investor lives in a state with no taxes on income, there is no benefit to limiting his purchases to in-state bonds. In this scenario, it’s a good idea to compare muni bonds from states with high-rated and high-yield bonds to build a diversified bond portfolio while also considering the annual tax bill in each of those states.
If a muni bond investor lives in a high-tax state, such as California with a 12.3 percent tax rate for residents with income in the top bracket (effectively 13.3 percent if you include the additional 1 percent surcharge on individuals earning over $1 million), then it makes sense to buy out-of-state munis to help reduce their tax burden.
Despite these general guidelines, investors should check on the muni bond tax status in their home state before making a purchase. Some states, such as Illinois, require residents to pay taxes on in-state muni bond yields. In this situation, the resident may find better deals with out-of-state munis by comparing coupon rates against the income taxes in those states.
