How to Run for Office in Massachusetts
Getting on the Ballot
Massachusetts candidates qualify by nomination papers - but with a two-step process that trips up newcomers: before papers can be filed, the signatures must be certified by the local registrars of each city or town where the signers live. Each sheet may contain signatures from only one city or town, papers go to those local registrars by a deadline two weeks before the state filing deadline, and only then are the certified papers filed - with the Secretary of the Commonwealth for state offices or the city or town clerk for local offices.
Collect far more signatures than required: registrars are only obligated to certify the required number plus one-fifth, names not certified the first time can't be certified later, and remaining signatures can still be challenged before the State Ballot Law Commission within days of filing.
For statewide offices, an additional hurdle applies: a candidate must receive 15% of the delegate vote at their party's convention to reach the primary ballot (a party rule with the force of long practice), and party candidates must prove enrollment in the party for the 90 days before filing.
Where Local Candidates File
City and town candidates file certified nomination papers with their city or town clerk, who is also the source for local signature requirements and election calendars. Campaign finance is handled by a separate agency: the Office of Campaign and Political Finance (OCPF) for state, county, and most city candidates, with candidates in smaller towns generally filing reports with the town clerk under OCPF's rules.
Worth Knowing
- The signature math is the whole game: one town per sheet, local certification first, a 20%-over certification cap, and a challenge window. Budget double the required signatures and start early.
- Nomination papers must not be altered in any way - stray markings can disqualify every signature on the sheet, and papers must be printed two-sided.
- Candidates for state office also file a Statement of Financial Interests with the State Ethics Commission (online), with the receipt included in the nomination filing.
