General Information

Who Must File

This property return (State Tax Form 3ABC) must be filed each year by all charitable, benevolent, educational, literary, temperance or scientific organizations and trusts owning real or personal property on January 1 in order to receive a local tax exemption on that property under G.L. c. 59, § 5 Clause 3 for the fiscal year that begins next July 1. Veteran organizations seeking exemption of real or personal property under G.L. c. 59, § 5 Clauses 5, 5A, 5B or 5C must also file this return.

When and Where Returns Must be Filed

A separate return must be filed on or before March 1 with the board of assessors of each city or town in which the organization owns the real or personal property. A return is filed when received by the assessors.

Filing Extension

The board of assessors may extend the filing deadline if the organization makes a written request and can show a sufficient reason for not filing on time. The latest filing deadline can be extended is the last day for applying for abatement of the tax for the fiscal year to which the filing relates.
