Here's everything you need to know.

How Long Does It Take To Form an LLC in Idaho?

It takes 7-10 business days to form an LLC in Idaho via mail or up to 3 days if you file online.
This is the total time the SOS takes to approve your articles of incorporation after receipt and includes the mailing time.
However, if you want your LLC approved sooner, you can file online, submit in person or pay for expedited processing.
LLC Processing Time
Idaho LLC processing time is the total time the SOS takes to approve your LLC so you can transact business in the state of Idaho.
The processing times differ based on the filing method you choose to submit your certificate of formation.
In Idaho, the SOS offers three filing methods with different processing times.
Let's look at each filing method.
1. Online Filings

Once you select your LLC name, you can incorporate the business online on the SOSBiz website [1].
Online filing can be approved instantly if there's less filing volume; otherwise, it can take up to 3 business days.
Before filing, you must create a user account using your email and phone number. Once you set up the account, log in with your username and password.
On the dashboard, navigate to the 'Business Forms' section and select the 'Certificate of Organization' tab under 'Limited Liability Company.' Foreign LLCs will select the Foreign Registration Statement.
Complete the details about your LLC and pay the $100 filing fee. You can pay this processing fee using Visa, MasterCard, Discover, or American Express.
For all online LLC filings, the SOS mandates you to have the following details before submitting the certificate of organization document.
- Name and address of your Idaho registered agent service
- Name or titles of your board of directors/managers
- Address of the managers/directors
The Idaho SOS website also has a resource page where you can get information on navigating your portal, filing different business forms, and how to amend your existing LLC forms.
2. Mail Filings

LLC owners can submit physical registration papers to the Secretary of State’s office via mail which takes 7-10 business days to get approved.
All paper filings in Idaho must be submitted with an additional $20 filing fee to cover the extra manual processing steps. The Secretary of State's office will automatically reject any paperwork submitted without this fee.
Note that the SOS only accepts checks or money orders as a payment method for paper form submissions.
When filling out the certificate of organization document, ensure that at least one of the principal managers signs it on the signature line section.
You'll also need to include a mailing address for future correspondence with the SOS. This will enable the SOS to send you LLC annual report notices through the term of your Idaho LLC.
Also, if there are other documents that you need to send to the SOS, like Assumed Business Name Reservation Certificate, in that case, you must attach them to the Certificate of Organization and mail them as a folder.
All domestic and foreign LLC paperwork is mailed to this address:
Office of the Secretary of State 450 N 4th Street PO Box 83720 Boise ID 83720-0080
3. In-person Filings
In-person filings are another option if you want to deliver your registration papers to the SOS office by yourself.
After downloading the Certificate of Organization form, please fill it out with all the details of your Idaho LLC and deliver the paper form with the $120 filing fee.
While in-person filings have a standard processing time of 7-10 business days, you can pay an additional $100 and have your papers processed within 8 hours.
All in-person filings are delivered to this official address:
Office of the Secretary of State 450 N 4th Street PO Box 83720 Boise ID 83720-0080
4. Expedited Filings

The Idaho Secretary of State offers expedited processing that allows owners of limited liability companies to receive their approved registration paperwork sooner.
Two expedited processing options are available in Idaho: 24-hour and same-day delivery.
You can pay an additional $40 and have your LLC papers processed in 1 business day.
Alternatively, if you want your LLC paperwork approved within the same day of application (in 8 working hours), you'll have to pay an additional $100 to the SOS [2].
