Process to become a candidate
See statutes: Chapter 10, Section 5, Article 7 of the Illinois Statutes
In Illinois, a candidate may run with an established political party, with a new party, as an independent candidate, or as a write-in candidate. Candidate qualification processes are detailed below.[1]
Political party candidates and independent candidates
Established political party candidates, new party candidates, and independent candidates must file nomination papers with the Illinois State Board of Elections in order to qualify for placement on the ballot. These nomination papers must be filed during the designated filing period. The filing period for established party candidates begins 127 days before the primary election and ends 120 days before the primary election. New party and independent candidates have a separate filing period. Their filing period begins 141 days before the general election and ends 134 days before the general election.[2][1]
Nomination papers include the following:[1]
- The statement of candidacy must indicate the candidate's address, the office being sought, and the candidate's political party designation (if applicable). This form also includes a statement affirming that the candidate is qualified for the office being sought. This form must be signed by the candidate and notarized.[3]
- The original statement of economic interests must be filed with the Illinois Secretary of State, which will then issue the receipt of the statement of economic interests for the candidate to file with the Illinois State Board of Elections. This form is not required from candidates seeking federal office. It is suggested that this form be filed at the same time as all other nomination papers, but it may be filed after the other papers as long as it is filed within the candidate filing period.[1]
- The loyalty oath form is optional. If a candidate chooses to sign it, he or she must affirm that he or she is not affiliated directly or indirectly with any organization that seeks to overthrow the government of the United States or the state of Illinois.[1]
- A petition containing the signatures of qualified electors. A candidate can begin circulating petitions 90 days before the last day of the filing period. Signature requirements for petitions vary according to the candidate's political party affiliation and the office being sought. Signature requirements are detailed in the table below.[1][4][1]
| Petition signature requirements | |||
|---|---|---|---|
| Office | Established party candidates | New party candidates | Independent candidates[5] |
| Statewide office (e.g., governor and lieutenant governor, attorney general, secretary of state, comptroller, treasurer) | 5,000 (no more than 10,000) primary voters belonging to the candidate's party | 1% of the number of voters who voted in the most recent general election or 25,000, whichever is less | 1% of the number of voters who voted in the most recent general election or 25,000, whichever is less |
| United States Representative | 0.5% of primary voters in the district belonging to the candidate's party | 5% of the total number of district voters who voted in the last general election | 5% of the total number of district voters who voted in the last general election |
| State senator | 1,000 (no more than 3,000) district voters belonging to the candidate's party | 5% of the total number of district voters who voted in the last general election | 5% of the total number of district voters who voted in the last general election |
| State representative | 500 (no more than 1,500) district voters belonging to the candidate's party | 5% of the total number of district voters who voted in the last general election | 5% of the total number of district voters who voted in the last general election |
Any objections to nomination papers must be filed no later than five business days after the filing deadline.[1]
Write-in candidates
Write-in votes will not be counted unless the candidate files a declaration of intent no later than 61 days before the election in which he or she is running. This form must indicate the office being sought by the candidate.[1][6]
Qualifications
Article IV of the Illinois Constitution states: To be eligible to serve as a member of the General Assembly, a person must be a United States citizen, at least 21 years old, and for the two years preceding his election or appointment a resident of the district which he is to represent.

Redistricting following the 2020 census
The Illinois State Legislature approved new state legislative maps in a special session on August 31, 2021. Gov. J.B. Pritzker (D) signed the new maps into law on September 24, 2021.[9] These maps were revised versions of maps enacted on June 4, 2021, that the legislature based on non-census population estimates. Following the release of census data in August, the legislature reconvened to develop and approve a revised map. These maps were later subject to a federal lawsuit that was decided on December 30, 2021, with the court upholding the maps enacted on September 24, 2021.[10] Learn more here.
