Filing: Declarations, Petitions and Fees

More local candidacies die at the filing counter than at the ballot box. The window is two weeks long, it opens almost three months before the election, and it closes at 5 p.m. sharp. The forms are short but sworn. The petitions need only five signatures, but the wrong five do not count. This lesson walks through every step for county, city, school and special district seats, with the statute for each rule and the 2026 and 2027 dates from the Secretary of State's election calendars.

The filing windows

Idaho counts filing deadlines backward from election day in weeks. The formulas sit in statute, and the Secretary of State turns them into dates each year in the election calendar.

• County offices, precinct committeemen and countywide highway districts (partisan, May primary): 8 a.m. on the twelfth Monday before the primary to 5 p.m. on the tenth Friday, filed with the county clerk (34-704(3)).
• Federal, state and legislative offices, for comparison: 8 a.m. on the thirteenth Monday to 5 p.m. on the twelfth Friday before the primary, filed with the Secretary of State (34-704(2)). House Bill 278 (2025) shortened that state-level window to one week while keeping two weeks for other offices, as part of a bill to standardize clerk deadlines.
• School, highway, fire, library, cemetery, recreation, hospital, water and sewer and other districts under the uniform district election law: 8 a.m. on the twelfth Monday to 5 p.m. on the tenth Friday before the election (34-1404(4)).
• City offices: the same 34-1404 window, applied by 50-410(1), filed with the city clerk.
• Irrigation districts are outside chapter 14: nominations go to the district secretary not less than 40 or more than 60 days before the election (43-201(4)).

Where you file

County offices are simple. Idaho Code 34-705 says candidates for county offices, single countywide highway district offices, and party precinct offices file with the county clerk, whether they are party or independent candidates.

City offices are filed with the city clerk under 50-410. Before a petition of candidacy is filed, the county clerk verifies the signatures as provided in 34-1807, with the city clerk standing in for the Secretary of State. The city clerk then checks the declaration and fee or petition against chapter 4 of Title 50 before accepting it.

School and special districts changed this year. Until July 1, 2026, 34-1404 said district nominating petitions were filed with the clerk of the political subdivision, who notified the county clerk. Senate Bill 1376, Session Law Chapter 235, rewrote it: petitions "shall be filed with the county clerk," the county clerk notifies the district and verifies qualifications within five days after filing closes, and the district clerk reviews and certifies the nominees to the county clerk within 48 hours. Each district must also give the county clerk a current map of its subdistricts by January 1 of any election year. The bill's statement of purpose says many districts in smaller counties "do not have regular hours of operation during the tight filing window."

The 2026 bill amended only 34-1404. Several district statutes still name another office:

• 33-502 still says a trustee declaration is filed "with the clerk of the board of trustees of the school district as provided in section 34-1404."
• 40-1305C says highway district petitions are filed with "the election official of the highway district."
• 22-2721 says soil and water conservation petitions are filed with "the secretary of the district."
• The Secretary of State's 2027 calendar lists the May 2027 window as filing "with the county clerk" and the November 2027 window as filing "with the clerk of the political subdivision" (citing 34-1404 and 50-410).

Until the legislature or the Secretary of State reconciles these, the safe course is to ask the county clerk, in writing, where your petition for your specific seat must be filed, and to keep the answer. If the answer names two offices, file a copy in both and get each one date-stamped.

Fees and petitions

Seat	Filing fee	Petition	Statute
County office (party candidate)	$40, to the county treasury	Or, in lieu of the fee, 5 qualified electors; commissioner signers must live in the commissioner district	34-617 to 34-623; 34-626
County office (independent)	See your clerk	Required: 5 qualified electors, plus a declaration of no party affiliation	34-708
Precinct committeeman	None	None	34-624
Countywide highway district (Ada)	$10, to the county current expense fund	Independents: 5-signature petition under 34-708 (added for these districts in 2026). 34-626, the petition-in-lieu section, lists only offices in 34-604 to 34-623	34-625
Mayor or city council	$40 nonrefundable, to the city treasury	Or a petition of candidacy signed by at least 5 registered qualified electors of the city	50-406
School trustee	None in statute	Required: at least 5 school district electors living in the candidate's trustee zone	33-502
Fire, library, cemetery, recreation, hospital, water and sewer, highway (ordinary)	None in 34-1404	Required: at least 5 electors of the candidate's zone or district	34-1404(1); 40-1305C
Soil and water conservation	None in statute	Required: at least 5 qualified electors owning land or living in the district	22-2721
Irrigation district	None in statute	Required: 6 electors (under 100 resident electors) or 12 (over 100), plus a nominee's oath	43-201

Under 34-701(4), fees may be paid in cash, cashier's check, money order, personal check, or credit or debit card, and the office may add its card processing cost to the fee. Under 34-717, fees are not refunded if you withdraw.

The declaration of candidacy

The Secretary of State prescribes one statewide form for declarations and petitions (34-701(1)). What the law requires it to contain:

• A sworn verification that you meet the legal qualifications for the office (34-701(3)). You are swearing to it, so the eligibility homework in lesson 2 comes first.
• Homestead disclosure. Whether you have claimed the homeowner's exemption under 63-602G, and the address of any such homestead, for you and a spouse (34-701(3)).
• Campaign contact information, including phone numbers (34-701(2)). District petitions must also include email addresses (34-1404(6)).
• Party affiliation, for partisan candidates. Under 34-704(1), a party candidate must be affiliated with the party at the time of filing, shown by a party affiliation form submitted with the declaration, and the clerk must reject a partisan primary declaration from someone who is not affiliated.
• No party, for city candidates. 50-406 says the city declaration shall make "no mention relating to party."

The city form printed in 50-407 ends with "Subscribed and sworn to before me" and a notary block, and each petition sheet carries a circulator's sworn statement that every signer signed in the circulator's presence. Plan for a notary. Many clerk's offices have one on staff; ask when you pick up the form.

Everything on these forms is public. Under 34-704(6) and 34-1404(7), the information in declarations and nominating petitions is available on request, with a narrow exception for judicial officers' home addresses and phone numbers. Your phone number and email will be in the hands of reporters, opponents and every group with a candidate questionnaire within days. Use a campaign phone and a campaign email.

Petitions: getting them right

The signature rules borrow from the initiative chapter. Idaho Code 34-1807 requires each sheet to carry a circulator's affidavit and has the county clerk examine the petition, strike names where the name, address or signature do not match a qualified elector of the proper area, and certify the count. City petitions go to the county clerk for verification before they can be filed with the city clerk (50-410). Leave time for that step: the clerk's office is checking petitions for every seat on the ballot during the same two weeks.

Several separate petition sheets may circulate at once, and they are treated as one petition when filed (50-407). Each signer writes a printed name, residence address and date, and signs. The circulator signs the affidavit, often before a notary, after the signatures are collected.

After you file

The filing officer verifies your qualifications and certifies the nominees for the ballot. For district races, 34-1404 now gives the county clerk five days after the close of filing. Then the challenge clock runs: any registered voter may ask the clerk to investigate your qualifications under 34-219 until the deadline the clerk sets (no earlier than 14 days after filing closes). The county clerk also publishes a notice of the filing deadline for all taxing districts 7 to 14 days before it closes (34-1405) and, each December, the county's election calendar for the next year.

Withdrawing

You may withdraw by filing a notarized statement of withdrawal with the office where you filed, stating who you are, the office and the reason. For county and precinct committeeman candidates the deadline is 5 p.m. on the ninth Friday before any election (34-717(3)), and for district candidates the same day (34-1405A). The fee stays with the county or city. And under 34-717(4), a partisan candidate who withdraws may not later be appointed to fill a vacancy unless the vacancy arose from a previous candidate's death. After the deadline, your name stays on the ballot whether you campaign or not.

Write-in candidates

Idaho counts write-in votes only for people who filed a declaration of intent saying they want the office and are legally qualified for it (34-702A(1)). Votes for anyone else are not counted, which is why a write-in campaign for a neighbor who never filed does nothing.

• County office or precinct committeeman (primary): declaration of intent with the county clerk by 5 p.m. on the ninth Friday before the primary (34-702A(3)). To become the party's nominee from a primary write-in, the candidate must also get at least five write-in votes (34-702(1)).
• Nonpartisan district offices: declaration of intent by 5 p.m. on the ninth Friday before the election, filed with the clerk of the political subdivision under 34-1407. The 2027 calendar says to file it with the county clerk. Ask which.
• City offices: 50-410 sends write-ins to 34-1407.
• How voters vote: in counties using optical scan ballots, a voter may not use a sticker or stamp, only handwriting (34-702A(5)).

A write-in declaration also matters where the law cancels uncontested elections, because a single write-in filing can turn a no-contest seat into a contested one. Under 34-1407(2), where a district statute says no election is held with one candidate, write-ins may still file until the ninth Friday, and if no candidate has filed by then, no election is held.

When only one person files

Idaho saves money on uncontested nonpartisan races by not holding them.

• Cities under 100,000: under 50-405(2), revised in 2024 by Senate Bill 1260, no election is held for mayor if one person has filed (counting write-ins), for a numbered seat if one person filed for it, or for at-large council seats if the number of filers is equal to or fewer than the seats. The city clerk declares the winners, who are installed at the first council meeting in January.
• School trustees: under 33-502B, if only one qualified candidate is nominated for a zone, or only one write-in has filed and turned in five zone electors' signatures, the board declares that person elected.
• Special districts: fire (31-1410(5)), cemetery (27-111(3)), library (33-2717), recreation (31-4306(2)), hospital (39-1330), water and sewer (42-3211), soil and water conservation (22-2721(4)) and irrigation (43-201A) all have their own version.
• County offices are different. Chapter 7 of Title 34 has no cancellation rule for partisan county races, so an unopposed county candidate still appears on the primary and general ballots.

Your name on the ballot

The ballot name comes from your declaration. Idaho has one statute on gaming it. Under 34-903A, if a candidate has legally changed their name to words that convey a political message, and a note would reduce voter confusion, the clerk must print "(A person, formerly known as ...)" after the name. Use the name people know you by, as it appears on your registration, and ask the clerk how they handle nicknames before you file.
