What Is a Municipal Investment Trust?

Municipal Investment Trusts are a type of Unit Investment Trust (UIT) that invests solely in municipal securities. UITs are investment companies that offer a fixed portfolio, generally consisting of stocks and bonds, as redeemable units to investors for a specific period. Municipal Investment Trusts allow individuals to invest in a diversified pool of municipal bonds, also known as munis, which offer tax-free income. These trusts are mostly designed for higher-income investors who are seeking tax-free income. They offer a monthly payout of income, as opposed to the quarterly or semiannual payment of interest, which is common with most individual municipal issues.


Municipal Investment Trusts, also known as MITs, constitute a specialized class of Unit Investment Trusts exclusively committed to investing funds in municipal securities. These MITs are meticulously crafted to cater to the financial needs of affluent investors in search of income streams entirely free from tax liabilities.

How Does a Municipal Investment Trust Work?

Municipal Investment Trusts (MITs) operate as a distinctive breed of investment entities. These entities, akin to mutual funds and closed-end funds, fall under the umbrella of investment companies. Their modus operandi revolves around offering investors fixed portfolios, typically comprising stocks and bonds, in the form of redeemable units. This arrangement spans a specified timeframe.

MITs, in particular, facilitate access to a diversified cache of municipal bonds, commonly called munis, with the added allure of tax-free income. Moreover, MITs demand only a nominal initial investment, rendering them accessible to a broader investor base. Notably, MIT units are vented by investment advisors, and unit owners have the privilege of redeeming these units directly to the trust at their net asset value (NAV), bypassing the need for secondary market transactions. This redemption process can be initiated either independently or with the assistance of an investment advisor.

Comparing Mutual Funds and Unit Investment Trusts

Unit Investment Trusts and mutual funds share common ground in that both comprise pooled investments, with multiple investors pooling their resources under the guidance of a portfolio manager. UITs are typically purchased and sold directly through the issuing company, though secondary market transactions are possible, resembling the accessibility of open-ended mutual funds. UITs are also introduced via initial public offerings (IPOs), akin to closed-end mutual funds.

However, a fundamental distinction arises: UITs are not subject to active trading. The securities within a UIT remain static unless an alteration occurs in the underlying investment, such as a corporate merger or bankruptcy. Assets within a municipal investment trust are held until maturity, with some even having specific maturity dates.

One notable cost differential lies in the management fees; municipal investment trusts generally levy lower fees than mutual funds, primarily due to reduced active management. Mutual investment trusts are typically acquired through brokers and often involve sales charges and minimum investment requirements. Conversely, municipal investment trusts do not impose commissions for executing sell orders.

Pros and Cons of Municipal Investment Trusts

Municipal Investment Trusts (MITs) have their merits, offering diversified muni-bond portfolios at an attractive cost. Notably, MITs provide a monthly income distribution, differing from the common quarterly or semiannual interest payments associated with individual municipal bonds. Furthermore, investors appreciate the stability of MIT holdings, which remain unchanged over time.

However, MITs' limited pre-maturity trading flexibility constrains some investment strategies. While mutual bond funds may entail higher costs, they often employ tactical approaches to capitalize on short-term market dynamics. For instance, certain municipal bond funds may sell bonds just prior to maturity if there is a favorable profit opportunity.

Additionally, mutual bond fund managers can swiftly seize new prospects. Suppose municipal hospital bonds face a temporary setback due to proposed legislation, but the manager believes the market's reaction is excessive. In this scenario, mutual fund managers can exploit the situation, a benefit not always available to municipal investment trust managers.


Municipal Investment Trusts are specialized Unit Investment Trusts focused exclusively on municipal securities. These trusts cater to higher-income investors seeking tax-free income, offering the advantage of monthly income payouts compared to the standard quarterly or semiannual interest payments associated with individual municipal bonds.

Despite their appeal, MITs have limitations, notably a lack of pre-maturity trading flexibility. In contrast, mutual bond funds, though potentially costlier, can capitalize on short-term market conditions and swiftly adapt to new opportunities. Ultimately, the choice between MITs and mutual funds hinges on an investor's financial goals and strategies.
