So, You Want to Run for Office? Meeting the Basic Eligibility Requirements is the First Step

Before you print a single petition or launch a campaign website, the first and most important question is this: Am I eligible to run for this office?

In Illinois, failing to meet the basic eligibility requirements can disqualify a candidate before the race even begins. Understanding the rules upfront saves time, money, and potential legal headaches later.

FIRST STEP

Every candidate in Illinois must meet two fundamental criteria. You must be a United States citizen and a registered voter in Illinois. If you can say “yes” to those first two questions, you are on your way. Next, you must be registered to vote at an address within the district or jurisdiction you want to represent. If you are not registered yet, this is an easy first step that can be completed quickly online. Go here: https://ova.elections.il.gov/ 

SECOND STEP

The next requirements to consider are age and residency requirements. These vary significantly depending on the office you are seeking. Never assume the rules are the same across the board. Always verify the exact requirements for your specific race.

Here are some common examples:

• Local offices (township, village trustee, school board, etc.): Often require you to be at least 18 years old and a resident of the district for as little as 30 days before the election.
• State legislative seats (Illinois House or Senate): These positions generally require you to be at least 21 years old, with two years of residency in the district and two (2) years in the state.
• Statewide offices (such as Governor): Typically require you to be at least 25 years old and a resident of Illinois for three (3) years prior to the election.
• Federal offices: These follow U.S. Constitutional rules. For example, U.S. House candidates must be 25 and a U.S. citizen for at least seven (7) years; U.S. Senate candidates must be 30 and a citizen for nine (9) years.

The best resource for precise details is the Illinois State Board of Elections Candidates Guide. To reach the Illinois State Board of Elections site, which has many of the resources you as a candidate will require to run for office, including the 2026 Candidates Guide, go here: https://www.elections.il.gov/RunningForOffice.aspx?MID=rOlNCTNZd9A%3D. Reviewing the guide early is one of the smartest moves a prospective candidate can make.

THIRD STEP

You should next carefully review Illinois’ incompatible offices rules if you currently hold another public office. These rules may require you to resign from your current position and specify exactly when that resignation must take effect. Illinois law generally prohibits holding two offices whose duties conflict with each other. For instance, you typically cannot serve simultaneously as a state legislator and a county board member.

FOURTH STEP

Next on your list of “to-dos” includes completing and filing a Statement of Economic Interests. Most candidates (except those running for federal office or certain party positions) must file a Statement of Economic Interests form. This disclosure form details your financial holdings, sources of income, and potential conflicts of interest. Depending on which seat you are seeking, you will file the completed Statement of Economic Interests form with the Illinois Secretary of State or your local county clerk. Once filed, you receive a file-stamped “receipt”; that receipt is important because you must provide it when submitting your nominating petitions. Even incumbents who filed a recent Statement of Economic Interests for their current position will almost always need to file a new one for the candidacy.

QUICK ELIGIBILITY SELF-CHECK

Before moving forward in the process, ask yourself:

• Am I a U.S. citizen and a registered voter in the correct jurisdiction?
• Do I meet the age and residency requirements for this specific office?
• Am I free from any incompatible office conflicts?
• Have I planned to file (or already filed) my Statement of Economic Interests?

If you meet all these conditions for the office you are pursuing, you have cleared the first major hurdle and are ready to focus on the petition circulation and filing process. Confirming eligibility early on in pursuit of office builds confidence and momentum for the rest of your campaign. It’s the essential foundation that allows everything else to move forward smoothly.
