DocumentIcon.jpg See statutes: Title 34 of the Idaho Code

Political party candidates

A partisan candidate for a local office must file a declaration of candidacy and either pay a filing fee or submit a petition containing the required number of signatures with the relevant city, district, or county.[1] A candidate for a statewide, state legislative, or federal office must file a declaration of candidacy and either pay a filing fee or submit a petition containing the required number of signatures with Idaho Secretary of State.[1]

For a candidate collecting signatures to be filed with a declaration of candidacy, each signature sheet must contain the signatures of qualified electors from a single county and must be verified by the appropriate county clerk prior to being filed with the Idaho Secretary of State. This applies to candidates for all statewide offices, state legislative offices, and congressional offices. Filing fees and signature requirements vary according to the office sought and are set out in the table below.[1]

Filing fees and petition signature requirements for partisan candidates
Office sought Filing fee Petition signature requirements
United States Senator $500 500
United States Representative $300 500
Governor $300 1,000
Lieutenant governor, secretary of state, state treasurer, state controller, attorney general, and superintendent of public instructure $200 1,000
State legislator $30 50

Independent candidates

An independent candidate must file a declaration of candidacy and submit a petition containing the required number of signatures with the Idaho Secretary of State.[1][2]

Each petition signature sheet must contain the signatures of qualified electors from a single county and must be verified by the appropriate county clerk prior to being filed with the Idaho Secretary of State. This applies to all statewide, state legislative, and congressional offices.[1] Candidates must collect 1,000 signatures for any statewide office, including U.S. Senate, 500 for U.S. House, 50 for state legislative districts, and five for county offices.[2]

Write-in candidates

A write-in candidate must file a declaration of intent form with the Idaho Secretary of State. A write-in candidate seeking the nomination of a political party in the primary election also must pay the filing fee required of that office within 10 days following the primary election date. A write-in candidate must also receive a minimum number of votes in the primary election in order to advance to the general election. These vote thresholds are as follows: [3]

  • 1,000 for any statewide office
  • 500 for a congressional district office
  • 50 for a state legislative office

A write-in candidate must file a declaration of intent form no less than 28 days before the primary or general election.[4]

Redistricting following the 2020 census

On November 12, 2021, the Idaho Independent Redistricting Commission formally submitted its final legislative map to the secretary of state. On November 10, 2021, the commission voted 6-0 in favor of the final legislative map.[7] The commission had earlier voted in favor of the map on November 5, 2021, but chose to recast their votes on November 10, 2021, due to concerns regarding Idaho's open meetings laws.[7][8][9] Idaho has 35 legislative districts, each of which elects one senator and two representatives.
