How to Register an LLC in Idaho (2026 Filing Guide)
To register an LLC in Idaho, you file a Certificate of Organization with the Idaho Secretary of State through the SOSBiz online portal. The filing fee is $100 online, or $120 by mail since paper filings carry an added $20 fee. Online filings are typically processed in about a week, with 1-business-day expedited processing available for an added $20. Once approved, you will still need an EIN from the IRS and a registered agent with a physical Idaho address. Idaho is one of the few states with no fee at all for its annual report.
AnyWhereFormations handles this filing end to end for founders who would rather not manage state portals and deadlines themselves. Below is the full process if you want to understand each step, or to file it yourself.
What You Need Before You File
- A business name that is distinguishable from every other entity on record with the Idaho Secretary of State and includes “limited liability company,” “LLC,” or an approved abbreviation
- A registered agent with a physical Idaho street address, not a P.O. box
- The name and address of at least one “governor” of the LLC (Idaho’s term for a member or manager, depending on your management structure)
- The name and address of an organizer to sign the filing
- A payment method for the $100 online filing fee
Steps to Register an Idaho LLC
1. Check name availability
Search the Idaho Secretary of State’s SOSBiz database to confirm your desired name is distinguishable from existing businesses on record under Idaho Code Section 30-21-301. The name must include “limited liability company” or an accepted abbreviation, and cannot falsely imply a government connection. You can reserve a name for 120 days (four months) for $20 online or $40 by mail if you are not ready to file yet.
2. Appoint a registered agent
Idaho requires every LLC to maintain a registered agent with a physical street address in the state, available during normal business hours to accept legal documents. This can be yourself, another Idaho resident, or a commercial registered agent service, which keeps your personal address off the public record and matters most for founders who do not have an Idaho address, including international founders.
3. File the Certificate of Organization
Submit your Certificate of Organization online through the SOSBiz portal, or by mail to the Secretary of State’s Boise office. You will list the LLC name, principal office and mailing address, registered agent information, and at least one “governor,” which is Idaho’s term for a member or manager depending on your management structure, plus an organizer signature. The fee is $100 online or $120 by mail. If your LLC offers a licensed professional service such as law, medicine, or accounting, you file a separate Professional LLC certificate instead of the standard form.
4. Draft an operating agreement
Idaho does not legally require an operating agreement, so without one your LLC is governed by the state’s default rules, which may not reflect what members actually agreed to. A written agreement sets your own terms for ownership, profit allocation, and decision-making, and banks frequently ask for one before opening an account.
5. Get a federal EIN
Apply for an Employer Identification Number directly from the IRS at no cost. Multi-member LLCs and any LLC with employees need one; single-member LLCs benefit from having one anyway to keep business and personal finances separate. Founders without a US Social Security Number can still get an EIN by submitting Form SS-4 by fax rather than through the online IRS system.
6. Complete Idaho Business Registration if applicable
If your LLC will sell taxable goods or services, hire employees, or operate in lodging, complete the Idaho Business Registration (IBR) process, which registers your business with the Idaho State Tax Commission, the Idaho Department of Labor, and the Idaho Industrial Commission in one filing. Idaho’s state sales tax rate is 6 percent. There is no fee to register.
7. Open a business bank account
Keep business funds separate from personal funds to preserve your LLC’s liability protection. Banks typically ask for your filed Certificate of Organization and EIN confirmation.
8. File your annual report
Idaho requires an annual report every year, due by the last day of your LLC’s anniversary formation month, filed online through SOSBiz. Unlike almost every other state, Idaho charges no fee at all for this filing. There is no late fee either, but the state will dissolve or revoke an LLC that goes 60 days past the due date without filing.
How Long Does Idaho LLC Approval Take?
Online filings through SOSBiz are generally processed in about a week, with 1-business-day expedited processing available for an added $20. Mail filings take longer once transit time is added on top of the same underlying review queue. Filing online is the faster and cheaper option in Idaho, unlike some states where online carries a premium.
Foreign Founders and International Applicants
Idaho does not require an LLC owner, governor, or organizer to be a US citizen or Idaho resident. International founders commonly use a commercial registered agent for the required in-state address and apply for an EIN by fax using Form SS-4 rather than the SSN-gated online IRS application. AnyWhereFormations manages both of these steps directly for non-resident founders.
How much does it cost to register an LLC in Idaho?
The state filing fee for the Certificate of Organization is $100 online or $120 by mail. Idaho charges no fee at all for the annual report, which is unusual among states.
Do I need a registered agent in Idaho?
Yes. Every Idaho LLC must maintain a registered agent with a physical Idaho street address, available during normal business hours to accept legal documents on the LLC’s behalf.
Can a non-US resident form an Idaho LLC?
Yes. Idaho does not require LLC owners, governors, or organizers to be US citizens or Idaho residents. Non-residents need a registered agent with a physical Idaho address and typically apply for an EIN by fax if they do not hold a Social Security Number.
Is an operating agreement required in Idaho?
No, but without one your LLC is governed by Idaho’s default statutory rules rather than terms you and your members actually agreed to. Most owners draft one regardless, and banks often request it.
Does Idaho charge a fee for the LLC annual report?
No. Idaho is one of the few states that charges nothing to file the annual report online. It is still due every year by the last day of your LLC’s formation anniversary month, and going 60 days past due can lead to dissolution.
How long does it take to form an LLC in Idaho?
Online filings are generally processed in about a week, with 1-business-day expedited processing available for an added $20.
