Find Idaho LLC, Corporation & Assumed Business Name Records
The Idaho Secretary of State’s SOSBiz portal is the official place to research Idaho corporations, LLCs, nonprofits, partnerships, foreign registrations and assumed business names.
The public search accepts a business name or file number. Open the full record to review status, filing type, addresses, registered agent, initial filing date, annual-report due information and available filing history.
Fastest search: enter the Idaho business name or file number in SOSBiz. The current interface starts with the keyword you enter, so broaden the search with Advanced Search if the legal name is uncertain.
Best identifier: once you locate the correct business, save its Idaho file number. It is more reliable than repeatedly matching similar business names.
No account needed just to research: the public search is available without filing an application. An SOSBiz account is required when you need to submit annual reports, amendments and other business filings.
How to Search Idaho Business Records
SOSBiz uses one primary field for a business name or file number. Start broad enough to catch spelling and legal-name differences, then narrow only if the result set is too large.
- Open the official SOSBiz Business Search.
- Enter the business name or Idaho file number.
- Run the default search first.
- If the record does not appear, open Advanced Search Options and use a broader match.
- Open the matching business rather than relying only on the result row.
- Save the file number before requesting a certificate or making a filing.
Use Advanced Search When a Basic Name Search Is Not Enough
| Search method | When it helps | Practical use |
|---|---|---|
| Name / file number | Normal entity lookup. | Use the file number whenever you already have it. |
| Starts With | You know how the legal name begins. | This is useful for exact opening words but can miss a keyword located later in the name. |
| Contains | You know only part of the business name. | Use this when the default search fails or the entity uses additional words. |
| Registered agent | You know the agent but not the exact business name. | One commercial agent may represent many unrelated entities. |
| Active-only filter | You need only current active records. | Remove this restriction when researching dissolved, forfeited or historical entities. |
| Filing-date range | You know roughly when the entity registered. | Useful when a common name returns many records. |

Idaho Annual Reports Are Required — but the Online Filing Fee Is $0
Idaho domestic filing entities, domestic LLPs and registered foreign entities generally file an annual report each year. The deadline is tied to the entity’s own registration anniversary rather than one statewide date.
| Annual-report item | Idaho rule |
|---|---|
| Frequency | Every year. |
| First report | Beginning one year after formation or Idaho registration. |
| Due date | By the end of the entity’s anniversary month. |
| Electronic filing fee | $0 state annual-report filing fee. |
| Paper filing | Paper annual-report forms are available by request; paper submissions generally carry the $20 manual-processing fee. |
Example: if an Idaho LLC’s Certificate of Organization became effective in March, its annual report is due by the end of March each year beginning the following year.
- Log in at SOSBiz.
- Access the correct business record.
- Select the Annual Report filing option.
- Review and verify the entity information.
- Sign and submit the filing.
- Save the filing confirmation for your records.
Certificate of Existence & Certified Business Copies
Idaho calls its good-standing-style document a Certificate of Existence. It confirms that the business is properly registered with the State of Idaho.
Certificate of Existence
Current fee: $10.
Idaho says the certificate is not required simply to operate a business, but a bank or another organization may request one.
Certified copy
Current fee: $10 plus $0.25 per page.
Use this when the recipient needs a certified copy of documents on file rather than status proof alone.
- Search for the business in SOSBiz.
- Open the correct business record.
- Select Request Certificate at the top of the record window.
- Complete the certificate request.
- Pay the $10 state fee.
- Use Idaho’s certificate-verification tool later if you need to confirm authenticity.
Open Idaho Business Resources and Certificate guidance.
Idaho Business Name Search & Reservation
The SOSBiz business search is the first screening tool for a proposed Idaho business name. Search close variations before paying for a domain, logo, signage or formation service.
Search before filing
- Search the full proposed name.
- Search the strongest distinctive word.
- Try Starts With and Contains.
- Remove LLC, Inc., Corporation and punctuation when needed.
- Review assumed business names as well as formal entities.
Name reservation
An Idaho legal entity name can be reserved for four months.
Electronic base fee: $20.
Paper total: $40, which includes the additional $20 manual-processing fee.
Open Idaho business forms and name-reservation fees.
Idaho DBA / Assumed Business Name Search
Idaho uses the term Assumed Business Name (ABN) for what many people call a DBA. ABNs appear in the Secretary of State business system, but an ABN does not create a separate legal entity.
| ABN task | Current base fee | Paper total |
|---|---|---|
| Register an assumed business name | $25 | $45 |
| Amend an assumed business name | $10 | $30 |
| Cancel an ABN online | No filing fee | Check current paper instructions |
Idaho’s current guidance says ABNs remain active until canceled by the owner; they are no longer subject to a periodic renewal requirement.
Idaho Registered Agent Requirements
Most Idaho business entities must maintain a registered agent to receive official notices and legal documents.
Individual registered agent
- Must live in Idaho.
- Must have an Idaho physical street address.
- Must be available during normal business hours.
- A P.O. box cannot be the registered office address.
Business registered agent
- Must be authorized to do business in Idaho.
- Must have a physical Idaho address.
- An Assumed Business Name cannot serve as the registered agent.
- The Secretary of State does not endorse specific agent services.
Common Idaho Business Filing Fees
Online filing is usually the lower-cost option. Idaho currently adds a $20 manual-processing fee to most paper filings that could otherwise be filed electronically.
| Service | Electronic / base fee | Paper total | Practical note |
|---|---|---|---|
| Public business search | Free public lookup | Not applicable | Search first before paying for other services. |
| LLC Certificate of Organization | $100 | $120 | Domestic Idaho LLC formation. |
| For-profit corporation Articles of Incorporation | $100 | $120 | Domestic Idaho business corporation. |
| Nonprofit Articles of Incorporation | $30 | $50 | Domestic nonprofit formation. |
| Annual report | $0 | Paper form by request; manual-processing fee may apply | Still mandatory despite the $0 electronic filing fee. |
| Name reservation | $20 | $40 | Reserves a legal entity name for four months. |
| Assumed Business Name | $25 | $45 | Creates a DBA/ABN record, not a new legal entity. |
| Foreign Registration Statement | $100 | $120 | Foreign corporations and foreign LPs also need a recent home-state Certificate of Existence/Good Standing. |
| Certificate of Existence | $10 | Check current request method | Formal Idaho registration-status proof. |
| Certified copy | $10 + $0.25/page | $10 + $0.25/page | Use only if certification is required. |

Many forms list an additional $40 expedited-service fee.
Same-day service
Same-day requests generally must be received by 1:00 p.m. Mountain Time.

If an Idaho Business Is Dissolved or Forfeited
If an Idaho entity has been administratively dissolved or forfeited, the Secretary of State says it may be eligible for reinstatement. Reinstatement is available only to Idaho entities.
- Log in to SOSBiz.
- Access the business record.
- Open the reinstatement filing.
- Resolve outstanding filing requirements.
- Review and submit the reinstatement.
Open Idaho Business FAQs for reinstatement guidance.
An Idaho SOS Record Is Not the Same as a Professional License
An SOSBiz record tells you what is filed with the Secretary of State. It does not automatically prove that the business or professional holds every occupational license, contractor registration, tax account or permit needed for its activity.
Open Idaho Division of Occupational and Professional Licenses.
- Identify the profession or regulated activity.
- Open the appropriate Idaho DOPL board or program.
- Use its public license or registration search.
- Compare the licensee name and status with the SOSBiz entity you found.
Common Idaho Business Search Problems
| Problem | Best next step |
|---|---|
| No result appears | Use Contains and search fewer distinctive words. |
| Too many results appear | Add another distinctive word, use the file number or narrow with Advanced Search. |
| Looking for an old entity | Turn off the active-only filter so dissolved, forfeited or withdrawn records can appear. |
| You know only the agent | Use the registered-agent option under Advanced Search. |
| Business does not appear in your account | The record may exist but not be associated with your SOSBiz login. Use the SOSBiz access-existing-business help process. |
| Annual-report due date is unclear | Open the entity record and check the filing date / annual-report due information. |
| You received an annual-report invoice | Remember that Idaho’s electronic annual-report state fee is $0; verify whether the invoice is from an optional third-party service. |
| You need official proof | Request the $10 Idaho Certificate of Existence after confirming the correct business record. |

Idaho Business Entity Search FAQ
1. Is the Idaho business entity search free?
Yes. The Idaho Secretary of State provides a public SOSBiz business search. Fees apply when you submit filings, request certificates or order certified records, not for the basic public lookup.
2. Where do I search for an Idaho LLC or corporation?
Use the official SOSBiz Business Search at sosbiz.idaho.gov/search/business. The main field accepts a business name or Idaho file number.
3. Why does my Idaho business search return no results?
The default search starts with the keyword you enter. If the word appears later in the legal name, use Advanced Search and a broader Contains-style search, or remove LLC, Inc. and punctuation.
4. Can I search Idaho businesses by registered agent?
Yes. SOSBiz includes Advanced Search options that can help research registered-agent information. Remember that one commercial registered agent may represent many unrelated businesses.
5. How much does an Idaho annual report cost?
The Idaho annual report has no state filing fee when filed electronically through SOSBiz. Paper submissions generally carry the separate manual-processing fee.
6. When is an Idaho annual report due?
The report is due annually by the end of the entity’s anniversary month, beginning one year after the entity was formed or registered in Idaho.
7. How much is an Idaho Certificate of Existence?
The current Secretary of State fee is $10. Search the business in SOSBiz, open the record and use the Request Certificate option.
8. What is an Idaho Assumed Business Name?
An Assumed Business Name, or ABN, is Idaho’s term for a DBA. It lets a person or entity operate under another name but does not create a separate legal entity or business license.
9. Does an Idaho registered agent need an Idaho address?
Yes. The registered agent must have a physical Idaho street address and be available during normal business hours. A P.O. box cannot serve as the registered office address.
10. Does an Idaho SOSBiz record prove a business is professionally licensed?
No. SOSBiz shows Secretary of State business-registration records. Professional or occupational licensing should be verified separately through Idaho DOPL or the responsible licensing agency.
Best Way to Use Idaho SOSBiz
Start with the public SOSBiz search, locate the exact entity and save its Idaho file number. Then review status, registered agent, addresses, annual-report due information and filing history before ordering certificates or making changes.
For ongoing compliance, remember the unusual Idaho advantage: the annual report itself has a $0 electronic filing fee, but it still must be filed every year by the end of the entity’s anniversary month.
