In order to get on the ballot in Iowa, a candidate for state or federal office must meet a variety of state-specific filing requirements and deadlines. These regulations, known as ballot access laws, determine whether a candidate or party will appear on an election ballot. These laws are set at the state level. A candidate must prepare to meet ballot access requirements well in advance of primaries, caucuses, and the general election.

There are three basic methods by which an individual may become a candidate for office in a state.

1. An individual can seek the nomination of a state-recognized political party.
2. An individual can run as an independent. Independent candidates often must petition in order to have their names printed on the general election ballot.
3. An individual can run as a write-in candidate.

This article outlines the steps that prospective candidates for state-level and congressional office must take in order to run for office in Iowa.

Information about filing requirements for local-level offices is not available in this article (contact state election agencies for information about local candidate filing processes).

Process to become a candidate

See statutes: Title II of the Iowa Code

There are four ways in which a candidate can gain access to the general election ballot: by primary election, by political party convention, by Non-party Political Organization (NPPO) convention, or by petition. These are detailed below.

Iowa allows any registered voter to challenge a candidate's nominating petition, as long as the challenge is made in writing and within 74 days of the corresponding election.

By primary election

A candidate seeking the nomination of a state-recognized political party in a primary election must be a member of that party. Non-party Political Organizations (NPPOs) are not permitted to participate in primary elections. A primary election candidate must file an affidavit of candidacy and nomination petition with the Iowa Secretary of State during the primary election filing period, which begins 99 days before the primary and ends at 5 p.m. on the 81st day before the primary. The affidavit of candidacy and the nomination petition must be filed simultaneously.

For the number of signatures required for nomination petitions, see the table below.

Formulas for determining signature requirements for political party candidates in primary elections
Office sought	Number of signatures needed
Governor or U.S. Senator	3,500 signatures, including at least 100 from 19 different counties.
State executive office (other than governor and lieutenant governor)	2,500 signatures, including at least 77 from 18 different counties.
United States Representative	1,726 signatures, including at least 47 from half of the counties in the district.
State Senator	100 signatures from the district.
State Representative	50 signatures from the district.

By political party convention

If a political party fails to nominate a candidate at the primary election, the party may hold a convention after the primary to nominate a candidate. That candidate must then file a political party convention certificate and an affidavit of candidacy. The deadline to file the convention certificate and affidavit of candidacy is the same as the general election filing deadline. However, a political party convention candidate may file his or her documents before the filing period begins for general election candidates.

By Non-party Political Organization (NPPO) convention

Non-party Political Organizations (NPPOs) are permitted to hold conventions to nominate their candidates. However, in order to qualify their nominations, NPPOs must meet the following requirements:

• To nominate a candidate to a state executive office or the United States Senate, 500 eligible electors, meaning people who meet all the requirements to register to vote, must attend the convention, and 25 counties must be represented by at least one eligible elector each.
• To nominate a candidate to the United States House of Representatives, 200 eligible electors who are residents of the congressional district the candidate seeks to represent must attend, including one eligible elector from at least half of the counties in the district.
• To nominate a candidate to the Iowa State Senate, 50 eligible electors who are residents of the senatorial district must attend, including one eligible elector from one-half of the precincts in the senatorial district.
• To nominate a candidate to the Iowa House of Representatives, 25 eligible electors who are residents of the representative district must attend, including one eligible elector from one-half of the precincts in the representative district.
• A convention may be held at any time as long as it is before the general election filing deadline.
• After the convention, the NPPO must provide a list of those who attended the convention, including their addresses, to the Iowa Secretary of State, along with a convention certificate and an affidavit of candidacy for the candidate nominated. These documents must be filed together during the general election filing period, which begins 99 days before the general election and ends at 5 p.m. 81 days before the general election.

By petition

A candidate who is not affiliated with any political party or NPPO can be nominated by petition. A NPPO candidate can gain ballot access in this manner if the NPPO cannot meet the convention attendance requirements described above. A petition candidates must file an affidavit of candidacy and nomination petition with the Iowa Secretary of State. These forms must be filed together by 5 p.m. 81 days before the general election.

The table below details the signature requirements necessary for obtaining ballot access by petition.

Formulas for determining signature requirements for NPPO candidates
Office sought	Number of signatures needed
United States Senator or governor	3,500 eligible electors, including at least 100 from at least 19 counties
Otherwise statewide executive offices	2,500 eligible electors, including at least 77 from at least 18 counties
United States Representative	1,726 eligible electors who are residents of the congressional district, including at least 47 eligible electors each from at least one-half of the counties in the congressional district

Petition requirements

See also: Methods for signing candidate nominating petitions

In some cases, political parties and/or candidates may need to obtain signatures via the petition process to gain ballot access. This section outlines the laws and regulations pertaining to petitions and circulators in Iowa.

In Iowa, most candidates are required to file nomination petitions with the Iowa Secretary of State. Any eligible elector may sign a candidate's nomination petition. Eligible electors do not have to be registered to vote, but they do need to be U.S. citizens, Iowa residents, and 18 years of age or older. Eligible electors cannot be judged incompetent to vote in a court of law, claim the right to vote anywhere else, or be convicted felons, unless a president or governor has reinstated their voting rights.

There is no limit to the number of nomination petitions an eligible elector may sign for different candidates. When signing a nominating petition, an eligible elector must include his or her address.

There is no designated start date for collecting signatures for nomination petitions. Signatures may be collected at any time. A candidate may sign his or her own nomination petition as long as the candidate is considered an eligible elector in the district he or she is seeking to represent.

The state code does not establish circulator requirements. Specifically, there are no residency requirements for circulators.

  • For other statewide offices, from 1,500 electors from at least 10 counties to 2,500 electors, including at least 77 from at least 18 counties.
  • For U.S. House candidates, from 375 electors to 1,726 electors, including at least 77 from at least 18 counties.
