Fidelity Massachusetts Municipal Income Fund (FDMMX) is an open-end mutual fund that seeks a high level of current income exempt from federal and Massachusetts personal income taxes by investing primarily in investment-grade municipal securities issued by or on behalf of the Commonwealth of Massachusetts and its political subdivisions; it normally invests at least 80% of assets in such securities, with allocations across various market sectors and maturities, and may invest more than 25% of assets in municipal securities financing similar types of projects. The fund is non-diversified and emphasizes investment-grade debt obligations, including Massachusetts state general obligations, turnpike authority revenue bonds, and miscellaneous municipal bonds, alongside limited cash equivalents; top holdings as of mid-2025 typically include Massachusetts State General Obligations (approximately 3% of portfolio) and cash positions (around 4-8%). Managed within Fidelity's municipal bond lineup under Fidelity Salem Street Trust, it targets tax-sensitive investors such as Massachusetts residents seeking income from high-quality, tax-exempt fixed income instruments.
Established in 1983 and domiciled in Boston, Massachusetts—the headquarters of Fidelity Investments—the fund operates principally within the U.S. municipal bond market, with a focus on Massachusetts-issued debt to maximize state tax exemptions.
Recent portfolio updates as of April 30, 2025, reflect ongoing active management with miscellaneous bonds comprising about 49% of assets, cash at 8%, and continued emphasis on Massachusetts state general obligations at 3%; the fund maintained its investment strategy amid market conditions, with no reported mergers, acquisitions, major partnerships, or structural changes in 2024-2025, though annual shareholder reports through January 31, 2025, confirm stable operations and compliance with tax-exempt objectives.
