MA S507

Adds a statutory definition of "in-kind contribution" to Massachusetts campaign finance law, covering non-monetary items such as free goods/services, below-market-rate charges, and payments made on behalf of a committee or candidate.

Requires state ballot question committees to report all in-kind contributions over $50, including donor names and addresses, dates received, contribution types, and values.

Mandates that state ballot question committees disclose new liabilities incurred, including creditor information and the purpose of each liability.

Increases reporting frequency for state ballot question committees to monthly filings until 60 days before the election, then twice-monthly filings until election day, with additional post-election reports through January 20 of each year until all liabilities are discharged.

Removes state ballot question committees from an exemption that had allowed less frequent reporting, aligning their disclosure requirements more closely with candidate committees.
