Idaho
Cheap candidate access, brutal initiative distribution
Idaho draws a sharp line between candidates and citizen measures. Candidate access is among the cheapest in the country — a legislative candidate pays $30 or collects 50 signatures — while an initiative needs 6% of registered voters in each of at least 18 of the state's 35 legislative districts. The Legislature tried to push that to all 35 districts in 2021; the Idaho Supreme Court struck the law down as an unconstitutional infringement on the reserved initiative power.
Signature and Fee Requirements
| Office / Measure | Requirement |
|---|---|
| U.S. Senate | $500 filing fee or 1,000 signatures |
| U.S. House | $300 filing fee or 500 signatures |
| Governor / Lieutenant Governor | $300 or 1,000 signatures / $200 or 1,000 signatures |
| Supreme Court justice / District judge | $300 or 1,000 signatures / $150 or 200 signatures |
| State Senate and State House | $30 filing fee or 50 signatures |
| Independent candidates | Declaration of intent plus petition: 1,000 statewide, 500 congressional, 50 legislative, 5 county or highway district |
| Statewide initiative | 6% of registered voters as of the last general election — 70,725 for 2026 — plus 6% in each of at least 18 of 35 legislative districts |
| Statewide referendum | Same 6% statewide and 18-district structure |
Filing Window and the Fee Alternative
Idaho's primary is in May and the candidate declaration window closes roughly ten weeks earlier, in March. Every partisan office offers a straight choice between the statutory fee and the listed signature count; the fee is almost always cheaper, so signature-in-lieu petitions are rare outside protest or indigency cases. Independents cannot appear on the primary ballot at all — they file a declaration of no party affiliation with their petition and go straight to the general election ballot.
Who May Circulate and One County Per Sheet
Idaho is a residency state: initiative and referendum circulators must be Idaho residents and at least 18, with residency judged on substance — principal home, employment, taxes, family, property — not a mailing address. Paid circulators must wear identification badges. This rules out importing an out-of-state crew, the biggest budget difference between Idaho and Nevada or Arizona. Every signature sheet may also carry signatures from one county only, and each county clerk verifies its own residents before certifying counts.
Timeline and Verification
Sponsors file a proposed initiative signed by 20 qualified electors; the Attorney General issues a Certificate of Review within 20 working days, sponsors refile within 15, and a ballot title is assigned within 10. Circulation then runs the shorter of 18 months or through April 30 of the election year, with signatures due May 1. County clerks verify within 60 calendar days and no later than June 30. There is no cure period and no post-deadline supplementation.
Recent Litigation
In Reclaim Idaho v. Denney (2021) the Idaho Supreme Court struck down S.B. 1110, which would have required 6% in all 35 legislative districts and shortened the circulation window, holding the initiative and referendum powers are reserved to the people and the law would have made them unusable. The 18-district rule was restored. Legislative interest in tightening the process has not disappeared, so verify the current statute each cycle.
Ballot Measures in Idaho
Idaho has direct initiative and referendum for statutes only — there is no citizen-initiated constitutional amendment, so constitutional change must originate in the Legislature. A statewide initiative requires 6% of registered voters as of the last general election, 70,725 for 2026, and that same 6% inside at least 18 of Idaho's 35 legislative districts. Sponsors file the measure with 20 qualified electors, obtain an Attorney General Certificate of Review and a ballot title, then circulate for the shorter of 18 months or through April 30 of the election year, with signatures due May 1. County clerks verify within 60 days and no later than June 30, followed by certification by the Secretary of State. Reclaim Idaho v. Denney (2021) is the governing backdrop: the Legislature may regulate the initiative power but not effectively nullify it.

Idaho Ballot Access FAQ
Should candidates pay the fee or gather signatures?
Almost always pay the fee. At $30 for a legislative seat and $300 to $500 for federal and statewide offices, Idaho's fees cost far less than collecting and verifying the alternative signature counts.
Can out-of-state circulators work an Idaho initiative?
No. Circulators must be Idaho residents and at least 18, with residency judged on substance rather than a mailing address. Paid circulators must also wear identification badges.
What is the 18-district requirement?
An initiative must collect signatures equal to 6% of registered voters in each of at least 18 of Idaho's 35 legislative districts, on top of the 6% statewide total. Falling short in an eighteenth district is fatal regardless of the statewide count.
Is the district requirement still 18 after S.B. 1110?
Yes. Reclaim Idaho v. Denney (2021) struck down S.B. 1110, which would have required all 35 districts, restoring the 18-district standard. Confirm current law each cycle given continued legislative interest in restricting the process.
