Step-by-step guide

How to Form an LLC in Idaho

Six clear steps — free annual report, no publication requirement, 5.8% flat income tax. Brendat handles everything while you focus on your business.

Choose a Name for Your Idaho LLC

Your Idaho LLC name must be unique among all businesses registered with the Idaho Secretary of State and must include a required designator.

Idaho Naming Rules:

Must include: "Limited Liability Company," "LLC," or "L.L.C."
Cannot use: Words implying a government agency (e.g., "FBI," "State Department")
Restricted words: "Bank," "Insurance," "University" require additional approval
Must be distinguishable: From all existing Idaho business names in the SOS database

Name Reservation Available

You can reserve your Idaho LLC name for 4 months with the Idaho SOS for $20. Brendat checks name availability before filing your Articles of Organization.

Appoint an Idaho Registered Agent

Every Idaho LLC must designate a registered agent — an individual or company with a physical Idaho street address — to receive legal documents and official state notices during regular business hours.

Who can be your registered agent?

Yourself: Must have a physical Idaho address and be available during business hours
A trusted individual: Any Idaho resident with a physical address
A professional service: Like Brendat — keeps your personal address off public records

Our Idaho address is listed on your Articles of Organization. Included in Standard and Premium packages.

File Articles of Organization with the Idaho Secretary of State

The Articles of Organization officially creates your Idaho LLC. You file it with the Idaho Secretary of State — online via the Idaho Secretary of State Business Portal or by mail.

Method	Fee	Processing Time
Online via ID SOS portal	$100	5–7 business days
By Mail	$100	4–6 weeks
Expedited (same day)	$100 + $40	Same business day

No publication requirement in Idaho

Idaho does not require LLCs to publish a formation notice in any newspaper. Once your Articles of Organization are approved, your LLC is fully formed.

Create an Operating Agreement

Idaho does not legally require an operating agreement, but it is strongly recommended for all Idaho LLCs. It establishes ownership, profit sharing, and management rules and protects your liability shield.

Your operating agreement should cover:

Ownership structure: Each member's percentage and capital contribution
Profit distribution: How and when profits are divided
Management: Who makes decisions and how voting works
Member changes: Process for adding or removing members
Dissolution: Steps to close the LLC if needed

Included in Brendat Standard and Premium

Brendat provides a professionally drafted Idaho operating agreement with your formation documents.

Get Your EIN (Employer Identification Number)

An EIN is your LLC's federal tax ID — required to open a business bank account, hire employees, and file taxes. You apply through the IRS for free.

US residents: Apply free online at IRS.gov — instant approval
Non-US residents: Apply by fax using IRS Form SS-4 — 4–6 weeks
Brendat handles this: Included in Standard and Premium packages

Open a business bank account right after

With your EIN and approved Articles of Organization, open a dedicated Idaho business bank account to keep personal and business finances separate.

File Your Idaho Annual Report — It's Free

Idaho LLCs must file an annual report every year with the Idaho Secretary of State to stay in good standing. The best part — Idaho's annual report is completely free. You still need to file it, but there's no fee.

Annual report fee: $0 — completely free
Due date: Last day of the month in which your LLC was formed each year
Filing: Online via Idaho SOS portal
Late penalty: Potential administrative dissolution after continued non-filing

Idaho's annual report is 100% free — but still required

While Idaho charges $0 for the annual report, you must still file it every year to keep your LLC in good standing. The deadline is the last day of your LLC's formation month each year. Brendat sends reminders before your specific deadline.

(303) 246-8693

How much does it cost to form an LLC in Idaho?

The Idaho state filing fee is $100. Brendat's service starts at $0 (Basic) or $149 (Standard). Total first-year cost with Standard is $249. Idaho's annual report is completely free — due the last day of your LLC's formation month each year. You must still file it, but there is no fee.

Is Idaho's annual report really free?

Yes. Idaho charges $0 for the annual LLC report — making it one of the handful of US states with no annual report fee. However, the annual report is still required to keep your LLC in good standing. It must be filed by the last day of the calendar month in which your LLC was originally formed each year. Failure to file can result in administrative dissolution. Brendat sends reminders before your specific monthly deadline.

What is Idaho's income tax rate for LLCs?

Idaho recently simplified its personal income tax to a flat 5.8% rate. For single-member LLCs and multi-member LLCs taxed as pass-throughs, income flows to members' personal returns at this flat 5.8% rate. Idaho's move to a flat rate makes tax planning simpler and more predictable for LLC owners.

How long does it take to form an LLC in Idaho?

Standard online processing with the Idaho Secretary of State takes approximately 5–7 business days. Same-day expedited processing is available for an additional $40. Mail filings take 4–6 weeks. Brendat submits your Articles of Organization within 1 business day of your order.

Does Idaho require newspaper publication for LLCs?

No. Idaho does not require LLCs to publish a formation notice in any newspaper. Once your Articles of Organization are approved by the Idaho Secretary of State, your LLC is fully formed with no additional steps needed.

Can a non-US resident form an Idaho LLC?

Yes. There is no US citizenship or residency requirement to form an Idaho LLC. Non-residents need a registered agent with a physical Idaho address (Brendat provides this). For your EIN, non-residents must apply by fax using IRS Form SS-4. Brendat assists with the complete process.
