How to run for local office in Connecticut

Connecticut municipal elections are held in November of odd-numbered years, most candidates are nominated by a party caucus in July, and the whole statewide voter file costs $300 from the Secretary of the State.

Facts checked against official sources · September 9, 2026

Connecticut has no county government. Its 169 towns and cities run everything local, and each one has two elected registrars of voters (one Democrat, one Republican) who keep the voter rolls in the statewide Centralized Voter Registration System, plus a town clerk who handles nominating petitions, absentee ballots, and municipal campaign finance filings. A first selectman, town council, or board of education candidate never deals with a county office because there is none.

Municipal elections are partisan and follow a fixed statutory clock: the election is the Tuesday after the first Monday in November of odd-numbered years, the primary is 56 days before that, party endorsements are made 56 to 49 days before the primary, and petitioning candidates file 90 days before the election. Absentee voting is now no-excuse, early in-person voting exists, and same-day registration is available on election day and during early voting.

Election authority: Connecticut Secretary of the State, Legislation and Election Administration Division (LEAD)
Voter file: Available for political and election purposes · $300 for the statewide voter registration data file, payable by check, credit card, or cash before release (Secretary of the State CVRS page and request form, checked 2026-09-09)
Campaign finance: eCRIS (used by state candidates and town committees; municipal candidates file paper forms with the town clerk) (State Elections Enforcement Commission (SEEC))
How voters vote: In person, with no-excuse mail voting
Registration deadline: Registrars hold the last regular admission session on the 18th day before election day (CGS 9-17); after that, use same-day registration on election day or during early voting (CGS 9-19j)
Local offices: Partisan. Candidates carry a party designation or run as petitioning candidates; the minority-representation rule in CGS 9-167a limits how many seats one party can hold on multi-member boards, which is why town committees often endorse fewer candidates than there are seats.

Who runs elections in Connecticut

Connecticut Secretary of the State, Legislation and Election Administration Division (LEAD) LEAD runs the Centralized Voter Registration System, sells the statewide voter data file, issues nominating petition forms, and answers ballot-access questions for municipal candidates (860-509-6100, LEAD@ct.gov). It does not accept municipal candidate filings; those go to the town clerk and the registrars of voters.

Each of Connecticut's 169 towns and cities has at least two registrars of voters, elected on a bipartisan basis, who maintain the voter rolls in the Centralized Voter Registration System and run polling places and early voting. The town clerk issues and receives absentee ballots, receives nominating petitions and party endorsement certificates, and is the filing repository for municipal candidate campaign finance reports.

Getting the Connecticut voter file

The voter file is the list of every registered voter, with the fields a campaign needs to target: address, party where the state records it, and vote history. In Connecticut it comes from Connecticut Secretary of the State (statewide voter registration data file); town registrars of voters (town registry list).

Access: Available for political and election purposes
Cost: $300 for the statewide voter registration data file, payable by check, credit card, or cash before release (Secretary of the State CVRS page and request form, checked 2026-09-09)
Format: CSV only (Voter Registration Data File Request form)
Vote history: Not confirmed
Phone numbers: Not confirmed
Updated: Snapshot at the time of purchase. Towns must enter each voter's election participation and voting method (in person or absentee) into the CVRS within 60 days after every election or primary.

Who can get it: Anyone may buy the statewide file by submitting the Voter Registration Data File Request form (and, for card payments, the credit card processing form) to LEAD by mail or email; the file is released after payment. Voter registry information may be used only for election-related, scholarly, journalistic, political, or governmental purposes under CGS 9-50d as amended by Public Act 26-1 s. 96.

Permitted use: Election-related, scholarly, journalistic, political, or governmental purposes only. No personal, private, or commercial use, including harassment, marketing, or republishing the data in print, digital, or broadcast form; violations draw a civil penalty from the State Elections Enforcement Commission (CGS 9-50d; data file request form, checked 2026-09-09).

County option: No county file exists. Your town's registrars of voters can produce the official registry list for the town from the CVRS; ask them for the current list and their fee. For a single-town race that is usually the practical route, with the $300 statewide file as the alternative if you want every town in a multi-town district in one CSV.

Only the voter's year of birth is released; month and day are withheld (Public Act 26-1 s. 96).
Voters in the Voter Registry Privacy Program (sworn safety affidavit) are excluded from released registry data.
Connecticut participates in ERIC for list maintenance, so the file is cross-checked against other states and motor vehicle records.

Whatever file you get, Culper imports it as a CSV and maps the columns for you. See how to read a voter file for what the fields mean.

Filing to run for local office in Connecticut

Connecticut municipal offices are partisan and there are two doors onto the ballot. Party route: the town committee's caucus or convention endorses candidates between the 56th and 49th day before the municipal primary and certifies them to the town clerk by 4 p.m. on the 48th day before the primary (CGS 9-391); anyone who wants to challenge the endorsed slate files a primary petition with the registrars by 4 p.m. on the 34th day before the primary (CGS 9-405), and the primary is held on the 56th day before the election (CGS 9-423). Petitioning route: file nominating petition pages with the town clerk by 4 p.m. on the 90th day before the election (CGS 9-453i) with signatures from the lesser of 1% of the votes cast for that office at the last election or 7,500 electors (CGS 9-453d).

File with: Town clerk (party endorsement certificates and nominating petitions); registrars of voters (primary petitions)
Filing fee: Confirm with the filing officer
Petition: Petitioning candidates: signatures of qualified electors equal to the lesser of 1% of the votes cast for the same office at the last election or 7,500 (CGS 9-453d); forms come from the Secretary of the State. Party-endorsed candidates need no petition; primary challengers need the petition described in CGS 9-405 and 9-406.
Partisan?: Partisan. Candidates carry a party designation or run as petitioning candidates; the minority-representation rule in CGS 9-167a limits how many seats one party can hold on multi-member boards, which is why town committees often endorse fewer candidates than there are seats.

Filing window: Everything keys off the municipal election date, the Tuesday after the first Monday in November of odd-numbered years (CGS 9-164). Primary: 56th day before the election. Party endorsements: 56th to 49th day before the primary, certified to the town clerk by the 48th day before the primary. Primary petitions: 34th day before the primary. Nominating petitions for petitioning candidates: 90th day before the election, 4 p.m., to the town clerk. Towns that moved their election to the first Monday in May of odd years by a three-fourths vote of the legislative body run the same offsets from that date.

Campaign finance rules in Connecticut

State-level campaign finance in Connecticut is overseen by State Elections Enforcement Commission (SEEC) through eCRIS (used by state candidates and town committees; municipal candidates file paper forms with the town clerk).

Where local candidates file: All municipal candidates, their candidate committees, exploratory committees, and political slate committees register and file their financial disclosures with the town clerk, not with SEEC (SEEC 2025 Municipal Election Campaign Overview). You register on SEEC Form 1; if you will raise no more than $1,000 and spend no more than $1,000, fund the race entirely from personal funds, or are funded solely by a town committee or slate committee, you attach SEEC Form 1B and are exempt from forming a candidate committee. Committees disclose on SEEC Form 20 (or the Form 21 short form when under $1,000 in a period). Town committees file with SEEC through eCRIS.

Contribution limits: Per SEEC's revised chart (January 2026): an individual may give $1,000 per election (primary and general count separately) to a candidate for chief executive officer of a town (mayor or first selectman) and $250 per election to a candidate for any other municipal office. A town committee may give $3,000 per election to a chief executive candidate and $1,500 to other municipal candidates; a political committee $1,500 and $375 respectively. Business entities may not contribute to candidates. The Citizens' Election Program is public financing for statewide and General Assembly races only; there is no public grant for municipal candidates.

Reporting: Quarterly reports due January 10, April 10, July 10, and October 10, plus a report on the 7th day before any primary or election in which the candidate appears; the January 10 report doubles as the post-election filing for November municipal elections, and committees of candidates in a primary file within 30 days after the primary (SEEC Guide for Municipal Candidates, January 2025).

You become a candidate the moment you solicit or receive a contribution, spend money (even your own) on the race, or receive a party endorsement, so register before you raise a dollar.
Municipal filing calendars for each cycle are posted on SEEC's Municipal Candidates and Treasurers page.

Limits and thresholds change. Treat the figures here as a starting point and confirm the current schedule with State Elections Enforcement Commission (SEEC) before you accept a check. Our campaign finance basics guide covers the bookkeeping every local candidate needs on day one.

How voting works in Connecticut

In person, with no-excuse mail voting. Connecticut voters vote in person on election day, in person during the early voting period, or by absentee ballot. Voters no longer need a reason to request an absentee ballot for any referendum, primary, or election (Secretary of the State absentee voting page, citing Public Act 26-42). Applications go to the town clerk on form ED-3 or through the online absentee request portal, which opens 45 days before the election.

Early voting: In-person early voting is held at a location the registrars designate; early voting sites are open 10 a.m. to 6 p.m., and 8 a.m. to 8 p.m. on the last Tuesday and Thursday before the election or primary (CGS 9-174). The number of early voting days for each type of election is set in CGS 9-163aa; the Secretary of the State posts each cycle's dates and locations.
Mail ballots: No-excuse absentee ballots for any active voter. Apply to the town clerk (form ED-3, by mail or hand delivery) or online; the online portal opens 45 days before the election and closes the day before it. For 2026 the general election request deadline was November 2 for a November 3 election.
Registration deadline: Registrars hold the last regular admission session on the 18th day before election day (CGS 9-17); after that, use same-day registration on election day or during early voting (CGS 9-19j)
Same-day registration: Yes

Knowing who has already voted: Three sources, all local. The town clerk's list of absentee ballot applicants is confidential until the third business day before the election, then available (CGS 9-140), so pull it that Thursday and again on election morning. During early voting the registrars check voters off the registry list at the early voting location, and you can ask them for the running list of who has voted early. After the election, every voter's participation and method (in person or absentee) is entered in the Centralized Voter Registration System within 60 days and shows up in the next data file you buy.

Local government in Connecticut: what you can run for

Connecticut has 169 towns and cities and no county government; counties survive only as geographic names, and regional councils of governments handle what counties do elsewhere. Most towns are governed by a board of selectmen led by a first selectman with a town meeting or representative town meeting as the legislative body; larger towns and cities use a mayor and council or a council-manager charter. Every town has an elected board of education (regional school districts serve some small towns), plus elected registrars of voters, and many have elected planning and zoning commissions, boards of finance, and constables. Boroughs and fire districts exist inside some towns.

When local elections happen: Municipal elections are held biennially on the Tuesday after the first Monday in November of odd-numbered years, unless a town's legislative body voted by three-fourths to hold them on the first Monday in May of odd-numbered years (CGS 9-164). They are never on the same ballot as the state election, which is in even years. The municipal primary falls 56 days before the election, in September (CGS 9-423).

Connecticut questions we get asked

How do I get the voter list for a Connecticut town election?

Two ways. Ask your town's registrars of voters for the official registry list, which they generate from the Centralized Voter Registration System. Or buy the statewide Connecticut voter registration data file from the Secretary of the State for $300 by submitting the data file request form to LEAD; it comes as a CSV, includes year of birth only, and may be used only for election-related, scholarly, journalistic, political, or governmental purposes under CGS 9-50d.

When are Connecticut municipal elections and how do I get on the ballot?

The Tuesday after the first Monday in November of odd-numbered years (November 2, 2027), or the first Monday in May in towns that chose May (CGS 9-164). Party candidates are endorsed by the town committee's caucus or convention between the 56th and 49th day before the September primary and certified to the town clerk by the 48th day; petitioning candidates file nominating petitions with the town clerk by 4 p.m. on the 90th day before the election with signatures from 1% of the last vote for that office (CGS 9-453d and 9-453i).

Where does a Connecticut board of education or town council candidate file campaign finance reports?

With the town clerk. SEEC's rules apply, but the town clerk is the filing repository for every municipal candidate committee, exploratory committee, and slate committee in Connecticut. Register on SEEC Form 1; if you will neither raise nor spend more than $1,000, file Form 1B and skip forming a committee. Only town committees file with SEEC in eCRIS.

What can someone give a Connecticut first selectman or council candidate?

Under SEEC's January 2026 chart, an individual may give $1,000 per election to a candidate for a town's chief executive office (mayor or first selectman) and $250 per election to a candidate for any other municipal office in Connecticut, with the primary and general election counted separately. Town committees may give $3,000 and $1,500 respectively. Business entities are prohibited from contributing.

Does Connecticut have early voting and same-day registration for local elections?

Yes to both. Early in-person voting takes place at a site the registrars designate, open 10 a.m. to 6 p.m. with extended 8 a.m. to 8 p.m. hours on the last Tuesday and Thursday before the election (CGS 9-174). Same-day registration is available on election day and during early voting (CGS 9-19j). The regular registration cutoff is the registrars' session on the 18th day before election day (CGS 9-17).

How do I know who has already voted absentee in my Connecticut town?

The town clerk keeps the list of absentee ballot applicants, and CGS 9-140 makes it confidential only until the third business day before the election or primary. From that point on, ask the clerk for the list, and ask the registrars for the list of voters checked off during early voting. Connecticut does not publish a statewide daily ballot-return file for municipal elections.
