Mass. Gen. Laws ch. 55, § 19
(b)
(3) A candidate or a treasurer of a candidate's committee for nomination or election to the state senate or house of representatives shall file with the director the information required pursuant to paragraph (2) according to the following schedule:
(i) on or before:
(iii) Except as otherwise provided, the end of the reporting period of each report required to be filed under the provisions of this paragraph shall be as of the tenth day preceding the last day for filing. The beginning of the reporting period for each report subsequent to the initial report shall be the day following the end of the reporting period of the last report filed.
The reports required to be filed by this paragraph shall be cumulative during the calendar year to which they relate.
(c) Except as otherwise provided in this section, all payments for campaign purposes made by or for the benefit of a candidate or by the treasurer of a political committee which are in excess of $100 shall be made only from funds on deposit in the depository through checks drawn on the depository and indicating that the checks are drawn on the campaign account of the candidate or the political committee involved. All checks drawn on the campaign account shall be payable either to the order of a named payee, not the candidate or treasurer, or, if the check is for not more than $100, may be payable to the candidate or treasurer. The memo line of the check shall be used by the political committee issuing the check to indicate the specific purpose of the expenditure. A political action committee or political party committee making an expenditure to support or oppose a candidate shall identify the candidate on the check.
A candidate or treasurer of a political committee required to designate a depository may make expenditures by wire transfer or other electronic means for broadcast, cablecast or other media services and for payroll services made in connection with employee deductions and withholdings. Expenditures may also be made by credit or debit card; provided, however, that a candidate or treasurer making an expenditure shall ensure that the date, amount and specific purpose of the expenditure is disclosed in accordance with regulations to be issued by the director; provided further, that a candidate or a treasurer of a candidate's committee for nomination or election to the state senate or house of representatives, shall provide such disclosures on the same schedule as set forth in paragraph (3) of subsection (b).
(d) The cashier or treasurer of the bank selected by any candidate or political committee as provided in this section shall file with the director by the fifth day of each month the following information:
(g) A political action committee or state committee of a political party organized pursuant to chapter 52 shall, within 7 days of its depository bank disclosing an expenditure made by the committee to support or oppose a candidate, review the bank's report and if the report does not identify the candidate supported or opposed, append to the bank's report a disclosure containing the name of the candidate and whether the expenditure supported or opposed the candidate.
A candidate or a political committee that fails to file any report required by this section shall be assessed and shall pay to the state treasurer a penalty not greater than $25 for each day the candidate or political committee has not filed the report.
A violation of this section shall be punished by imprisonment for not more than 6 months or by a fine of not more than $500.
