Before you can benefit from the advantages of an LLC-structured business in Idaho, it is important to note that the Secretary of State has to receive, verify, process, and approve your application.

As a Master's Degree holder in tax law and an expert in mergers and acquisitions, I helped businesses and individuals form limited liability companies in various states.

Together with our experienced LLC specialists in Idaho, we navigated the Idaho SOS website to determine the turnaround time for each filing method.

Quick Summary

  • It takes 7–10 business days to form an LLC in Idaho by mail, and up to 3 working days if filed online.
  • The Idaho Secretary of State offers expedited processing, which costs $40 (1 business day) and $100 (same-day service).
  • According to the US Small Business Administration, 99.2% of Idaho's businesses are small, totaling 188,603, highlighting the state's strong entrepreneurial support and relevance to LLC formation timelines.
  • In my experience, it’s ideal to file online and avail of the expedited service to save time and make your business operational as quickly as possible.

What is The Fastest Way to Start an LLC in Idaho?

The fastest way to start an LLC in Idaho is by paying for expedited service. You can choose between a 24-hour turnaround or same-day processing.

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 [1] [2].

LLC Processing Time in Idaho

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 SOS offers three filing methods with different processing times.

Let's look at each filing method.

1. Expedited Idaho LLC Processing Time (1 business day + $40, 8 working hours + $100)

Two expedited processing options are available in Idaho: 24-hour and same-day delivery.

When clients request expedited service via mail, the process is usually completed within the same day. This enables them to start their businesses as soon as possible.

2. Non-Expedited Idaho LLC Processing Time By Mail (7-10 business days)

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.

When I filed by mail, I submitted an additional $20 (check or money order) filing fee to cover the extra manual processing steps and sent the LLC paperwork to this address:

Office of the Secretary of State
450 N 4th Street, PO Box 83720
Boise ID: 83720-0080

3. Idaho LLC Processing Time Online (up to 3 business days)

Online filing can be approved instantly if there's less filing volume; otherwise, it can take up to 3 business days. That's why we prefer filing online, since it's more efficient and convenient.

Once you select your LLC name, you can incorporate the business online on the SOSBiz website [3].

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.

4. Idaho LLC Processing Time In Person (7-10 business days)

In-person filings have a standard processing time of 7–10 business days.

Office of the Secretary of State
450 N 4th Street, PO Box 83720
Boise ID: 83720-0080

Factors Influencing The Formation Timeline Of Illinois LLCs

Here are the factors that can prolong the processing time of your Illinois LLC:

  • The volume of applications: The processing time may be delayed due to the high volume of filings since the state manually reviews each application.
  • Documentation issues: Formation papers containing incorrect or incomplete details are rejected by the state; as such, you’ll have to amend the mistake and refile the document.
  • Weekends and holidays: Since the state doesn’t conduct business during this period, your application will be reviewed on the following working day. That's why I always file early on the weekdays. 

Despite possible delays, Idaho's supportive business environment facilitated the creation of 11,977 new businesses between March 2021 and March 2022, as documented by the US Small Business Administration.

“Remember, Idaho LLC formation speed relies on the filing method you choose. But even after approval, ensure you have a solid operating agreement in place to protect your business.”
