If you’re looking for a safe investment that is likely to deliver slow yet steady returns over the long haul, and where you don’t have to pay federal or local taxes, a tax-free municipal bond might be a good option. In order to avoid local taxes, simply invest in a local (city or state) municipal bond. If you invest outside of your own area you might have to pay taxes, which wouldn’t make a tax free municipal bond as appealing as some other safe investment options, such as corporate bonds or certificates of deposit (CDs). (For more, see: The Basics of Municipal Bonds).

There are four big benefits to investing in a tax free municipal bond exchange-traded fund (ETF): liquidity, diversification, safety, tax free. As far as liquidity, unlike open-end municipal bonds or individual municipal securities, tax free municipal bond ETFs allow you to move in and out of your position if necessary. There are also no front-end or back-end sales charges. And expense ratios are lower. This last point plays a big role in choosing the right tax free municipal bond ETF. What follows below should help guide you in the right direction (numbers are as of Jan. 30, 2015).

80,000+ Municipal Bonds

With more than 80,000 issuers of municipal bonds in the United States, you have many more options than the tax free municipal bond ETFs listed above. Just keep in mind that these ETFs offer a lot more diversification. (For more, see: Top 2014 Muni Bond ETFs).

If you choose not to go the ETF route, you should know that there are two types of bonds: revenue bonds and general obligation bonds.

Revenue bonds are issued by transportation systems, hospitals, power systems, sewer systems, water systems and the like. These bond issuers generate revenue by selling tickets and collecting on bills. Part of this revenue is then returned to you, the investor.

General obligation bonds are issued by states, cities, towns, school districts and so forth. The bond issuer relies on taxes to in order to repay the bonds. Taxes can mean income taxes, corporate taxes, property taxes, sales taxes, excise taxes and more. So instead of complaining about taxes perhaps it’s time to invest in municipal bonds, which will be tax free (in most cases), and allow you to collect on other people’s taxes.

The Bottom Line

It would be difficult to go wrong investing in tax-free municipal bonds or municipal bonds in general for that matter. However, the former provides you with a lot of diversification. (For more, see: Why You Should Invest in Municipal Bond ETFs).
