About MFSSX

MFS Massachusetts Municipal Bond Fund Class A is an actively managed municipal bond mutual fund focused on generating a high level of current income that is exempt from U.S. federal and Massachusetts personal income taxes, while also considering capital appreciation. The strategy invests primarily in Massachusetts municipal securities and applies sector and security selection alongside yield curve analysis to drive performance, seeking “double tax-free” income for in-state residents. Managed since 1985, the fund benchmarks against the Bloomberg Municipal Bond Index and maintains a diversified portfolio of Massachusetts issuers across essential services, transportation, housing finance, and dedicated sales tax revenue streams. It offers monthly income distributions and is structured with a front-end sales charge at the share class level. Within the municipal market, the fund serves investors seeking state-specific tax-exempt income with professional credit research and duration management typical of intermediate municipal bond strategies. According to fund materials, it emphasizes total return with an income priority, supported by fundamental analysis of municipal sectors, credit quality, and interest rate positioning.
