The campaign finance law, Chapter 55 of the Massachusetts General Laws, is a comprehensive statute governing the financing of political campaigns in the Commonwealth of Massachusetts. The state requires, for example, that candidates and political committees disclose all contributions received and expenditures made. 

These reports must be filed whether or not money has been raised or expended during the reporting period and whether or not the candidate is nominated or elected. 

Pre-election Reporting: Due on or before the 8th day preceding the city or town general election

Post-election Report: Due on or before the 30th day following the general election
