Investors typically think of municipal bond products as being tax-free. However, in many cases, that is not the reality.
Although the interest income from municipal bonds is typically tax-free at the federal level, any price gains realized on buying and selling the bonds within the product can create a tax liability. Within Morningstar’s Municipal National Intermediate universe of mutual products, the average municipal bond fund surrendered 5 basis points (0.05%) per year of performance to taxes for the 10 years ending December 2013. In a year in which tax rates increased, the average tax cost for the same universe in 2013 was almost double the 10-year average, at 9 basis points (0.09%). This may not sound like much, but in the current low interest rate environment, every basis point counts.
Tax efficient municipal bond portfolio management techniques
Only 23% of the funds in the Morningstar Municipal National Intermediate universe have not had a tax distribution in the 10 years ending 2013. How do they do it? Here are some examples of techniques they may have used.
Tax-loss harvesting
Among other things, many savvy managers may apply tax loss harvesting techniques to help manage taxable distributions. For example, last year the broad municipal bond market experienced negative returns. While accounting for transactions costs, a portfolio manager could comb through the portfolio looking for securities to sell at a loss and replace with securities of equal diversification benefits. The losses could either be used to offset any securities that were sold at a gain that year, or tucked away as a tax loss carryforward. A hypothetical example is given below where characteristics for the two bonds are nearly identical, except for the issuer. The difference in issuer helps prevent a “wash sale,” which occurs when you sell or trade stock or securities at a loss and within 30 days before or after the sale you buy substantially identical stock or securities. You cannot deduct losses from a wash sale.
The benefit of a tax loss carryforward is especially relevant when interest rates are falling (and bond prices are increasing) as we’ve seen in early 2014. This allows a manager to continue to apply an active strategy of selling expensive bonds and purchasing cheap bonds, even if a capital gain is incurred. In the absence of a tax loss carryforward, the hurdle to sell a bond with a potential capital gain is much higher, and could prevent a tax-sensitive manager from actively trading the portfolio.
