Updated September 4, 2026. Quick answer: a dissolved Idaho corporation reinstates by filing Application for Reinstatement, filed with the Idaho Secretary of State (via the SOSBiz online portal; paper filing by request only) under Idaho Code §30-21-603 (Reinstatement), Idaho Uniform Business Organizations Code, Title 30, Chapter 21; dissolution procedure at §30-21-602, but only within 10 years of dissolution.
If you’d rather have the reinstatement filed for you
Bizee can prepare and file the Idaho reinstatement paperwork described above on your behalf. State filing fees and any back taxes owed are separate, and you pay those directly either way.
Bizee’s BBB rating, verified directly against BBB’s own listing on September 2, 2026: a C, not accredited. BBB’s own finding: the business “has failed to resolve underlying cause(s) of a pattern of complaints,” with 83 complaints filed. Most complaints we found described difficulty canceling recurring services and strict refund policies, worth knowing before you hand over a card for the year-two renewal. Check BBB’s current listing yourself before you buy; a rating we didn’t just verify is worse than none.

The filing, and what Idaho calls it
Idaho calls this process ‘reinstatement.’ It is triggered by administrative dissolution under §30-21-602 (e.g., failure to file required reports/pay fees or maintain a registered agent). A domestic entity may apply to the Secretary of State for reinstatement within 10 years of dissolution, must pay all fees/taxes/interest/penalties owed at dissolution plus those that would have accrued during the dissolved period, and – if its original name is no longer available – must adopt a substitute name meeting current requirements; reinstatement relates back to the dissolution date.
How long you have to reinstate
Idaho does not let a dissolved corporation reinstate forever. You have just 10 years from the dissolution or revocation date; miss it and the only path back is forming a new entity from scratch, losing the original formation date and history. A domestic filing entity administratively dissolved under §30-21-602 may apply to the Secretary of State for reinstatement not later than 10 years after the effective date of dissolution. (Idaho Code §30-21-603(1))
What you must pay before it goes through
Idaho will not reinstate the corporation until every year it sat delinquent is paid for. To be reinstated, the entity must pay all fees, taxes, interest, and penalties that were due to the Secretary of State at the time of dissolution, plus all fees, taxes, interest, and penalties that would have become due during the period the entity was dissolved. (Idaho Code §30-21-603)
Whether your name is still yours
Your original name is not guaranteed to still be yours. The reinstatement application must state the entity’s name at dissolution ‘and, if needed, a different name’ satisfying §30-21-301 – meaning the statute itself anticipates the original name may no longer be available and requires a substitute in that case. Nothing in the sections fetched this session (§30-21-602, §30-21-603) describes a fixed grace period during which the name is held for the dissolved entity. Check Idaho’s business-name database before assuming the reinstatement filing will go through under the old name. (Idaho Code §30-21-603(1)(a), referencing §30-21-301)
What the filing costs
Not confirmed at a primary source this session. The Idaho SOS business-forms and business-FAQ pages fetched directly did not list a reinstatement fee amount – they route filers to the SOSBiz online portal or direct them to call Business Services at (208) 334-2301. A commonly cited $30 base fee appears only on formation-service aggregator sites, not on any sos.idaho.gov page reachable this session, so it is omitted rather than repeated as fact.
What this page does not answer
Reinstating the entity at the state level and squaring things up with the IRS are two separate processes. Late federal returns, penalty abatement requests, and reinstating a lapsed EIN’s associated accounts are governed by federal law, not by Idaho’s corporation statute, and this page does not source them. We have the state-filing answer at primary and the federal-cleanup answer not at all.
This page covers a for-profit business corporation. If you are reinstating an LLC in Idaho instead, the filing, fee and statute are different: see reinstating an LLC in Idaho.
