The Idaho Legislature: who, when and where

The Idaho Legislature is a part-time body that writes most of its laws in about twelve weeks. In 2026 it convened on Monday, January 12 and adjourned on Thursday, April 2. Everything that happens in Boise during those weeks runs on a calendar, and the calendar is the first thing a citizen or advocate needs to learn. Miss a deadline by a day and an idea waits a full year.

The calendar

Article III, Section 8 of the Idaho Constitution says regular sessions start on the second Monday of January "unless a different day shall have been appointed by law." The law does appoint one. Idaho Code 67-404 convenes the session at noon on the Monday on or nearest January 9. Usually that is the second Monday anyway, as in 2026. Not always: in 2025, January 9 fell on a Thursday, so the session opened Monday, January 6. There is no fixed end date. The session ends when both chambers vote to adjourn sine die, which in practice means the budget is done and leaders have run out of patience. Late March or early April is typical. Some years run longer, usually because of budget or tax fights.

Before 1969 Idaho met only every other year. Voters approved annual sessions in November 1968. There is also a short organizational session on the first Thursday of December after each general election, when new members are sworn in and leaders and committee chairs are chosen.

Period	What happens	What you can do
Summer and fall (interim)	Interim committees study topics. Agencies draft rules and hold negotiated rulemaking meetings. Lawmakers and lobbyists draft bills.	Talk to your legislators at home, when they have time. Comment on agency rules.
December, after an election year	Organizational session: leaders elected, committees assigned.	Note who chairs the committees you care about.
Monday on or nearest January 9	Session opens. Governor's State of the State and budget address.	Read the governor's budget request.
First weeks	Personal bills allowed (12 legislative days in the Senate, 20 in the House). Committees review agency rules.	Watch germane committees for rule review hearings.
Around day 36	Only a few privileged committees may still introduce bills.	Late surprises come from these committees. Watch them.
March into April	Floor votes pile up. Budget bills pass. Sine die.	Track the governor's decisions on passed bills.

Special sessions

The governor can call an extraordinary session by proclamation. Since voters approved SJR 102 in November 2022, the legislature can also call itself back. Article III, Section 8(2) requires the Senate president pro tempore and the House speaker to convene a special session within 15 days after receiving a joint written petition signed by at least 60 percent of the members of each house. Either way, the session can only take up the subjects listed in the proclamation or petition, plus paying for the session itself.

The two chambers

Idaho has 35 legislative districts. Each district elects one senator and two representatives, so there are 35 senators and 70 representatives. All 105 serve two-year terms and are elected in November of even-numbered years. Members take office on December 1 after the election. An independent redistricting commission, created by a 1994 constitutional amendment, redraws the districts after each census.

The lieutenant governor presides over the Senate. The Senate also elects a president pro tempore, who runs the chamber day to day. The House elects a speaker. In Idaho the speaker and the pro tem hold most of the procedural power: they assign bills to committees, and committee assignments flow from leadership.

A bill can start in either chamber, with one exception. Article III, Section 14 says bills "for raising revenue" must start in the House. The other chamber can amend or reject anything.

Committees are where bills live or die

Each chamber has standing committees organized by subject: education, health and welfare, resources, transportation, local government and so on. When a bill is introduced it is referred to one of them. The chair decides whether and when it gets a hearing. No hearing, no vote. The Legislature's own guide says plainly that many bills "die in committee," and that is the usual way an idea fails in Idaho. Floor defeats are rarer and get more attention.

One committee belongs to both chambers. The Joint Finance-Appropriations Committee, made up of senators and representatives, writes the state budget one agency at a time. Its budget bills then go to the floor of each chamber like any other bill. The governor can veto individual items in an appropriation bill (Article IV, Section 11), a power he does not have over ordinary bills.

Introduction deadlines

Idaho uses deadlines counted in legislative days to force ideas out early. The Legislature's guide summarizes them this way: after the 20th day in the House and the 12th day in the Senate, only committees may introduce bills. After the 36th day, only a short list of committees may. In the Senate that list is State Affairs, Finance, and Judiciary and Rules (Senate Rule 11). In the House it includes State Affairs, Appropriations, Education, Revenue and Taxation, Health and Welfare, and Ways and Means. Constitutional amendments have their own deadline: Joint Rule 20 requires a joint resolution proposing one to be introduced by the 36th day.

The website you will live on

Almost everything you need is on legislature.idaho.gov, and it is better organized than most state sites. The pages worth bookmarking:

• Who's My Legislator? Type an address, get your three legislators and their contact details.
• Legislation for the current session: every bill, joint resolution, memorial and concurrent resolution, numbered and linked to its text, statement of purpose and history.
• Standing committees: membership, agendas, minutes, and the testimony registration link.
• Reading calendars for each chamber, which show what is up for a floor vote today.
• Live audio and video of floor sessions and committee meetings, streamed with closed captions through a partnership with Idaho Public Television.
• Vetoes: a list of vetoed bills with the governor's veto letters. Check it against the governor's own releases. Gov. Little announced five vetoes after the 2026 session, while the Legislature's 2026 page listed four as of October 2026.
