Section 3D. A city or town which accepts the provisions of this section is hereby authorized, subject to the approval of the commissioner, to design and designate a place on its municipal tax bills, or the motor vehicle excise tax bills, or to mail with such tax bills a separate form, whereby the taxpayers of said city or town may voluntarily check off, donate and pledge an amount not less than $1 or such other designated amount which shall increase the amount otherwise due, and to establish a city or town aid to the elderly and disabled taxation fund for the purpose of defraying the real estate taxes of elderly and disabled persons of low income.
Any amounts donated to said fund shall be deposited into a special account in the general treasury and shall be in the custody of the treasurer. The treasurer shall invest said funds at the direction of the officer, board, commission, committee or other agency of the city or town who or which is otherwise authorized and required to invest trust funds of the city or town and subject to the same limitations applicable to trust fund investments, except as otherwise specified herein.
