Forming an LLC?

How to Start an LLC in Idaho

Benefits of Starting an LLC in Idaho

Idaho offers a genuinely business-friendly environment for LLC formation, with several advantages that stand out compared to other states.

Free Annual Reports

Idaho charges $0 for annual report filings, saving your LLC a recurring cost that ranges from $50 to $300+ in most other states.

Low Formation Costs

At just $100 to file online, Idaho’s formation fee is well below the national average, and dissolution is also free if you ever need to close up shop.

No Publication Requirement

Unlike states such as New York and Arizona, Idaho does not require you to publish a newspaper notice after forming your LLC.

Same-Day Expedited Filing

For an additional $40, the Idaho Secretary of State will process your filing within 8 business hours, getting your LLC up and running fast.

1Name Your Idaho LLC

Your LLC name must be distinguishable from every other business entity registered with the Idaho Secretary of State. Before you commit to a name, run a search on the Idaho business name database to confirm availability.

Idaho requires your LLC name to include one of these designators:

  • “Limited Liability Company”
  • “LLC”
  • “L.L.C.”

Your name cannot imply the LLC is a government agency, bank, or insurance company without proper licensing. Avoid names that are misleadingly similar to existing Idaho entities.

If you find a name you like but are not ready to file, you can reserve it for 120 days by submitting a name reservation application with a $20 fee through the Idaho Secretary of State.

Yes. You can file an amendment to your certificate of organization with the Idaho Secretary of State to change your LLC’s legal name.

2Choose a Registered Agent in Idaho

Every Idaho LLC must designate a registered agent. This is the person or company authorized to receive legal documents, government notices, and service of process on behalf of your LLC.

Your registered agent must meet these requirements:

  • Be an individual who resides in Idaho, or a business entity authorized to operate in Idaho
  • Have a physical street address in Idaho (P.O. boxes are not allowed)
  • Be available during normal business hours

You have three main options:

  • Be your own registered agent. Free, but your personal address becomes part of the public record, and you must be available at that address during business hours.
  • Appoint a friend or colleague. Also free, but places an obligation on someone else to always be available.
  • Hire a professional registered agent service. Typically $50 to $300 per year. This keeps your home address off public filings and guarantees someone is always available to accept documents. You can compare Idaho registered agent services to find the right fit.

Yes. Idaho law requires every LLC to maintain a registered agent with a physical street address in the state at all times. If your agent resigns or your address becomes invalid, you risk missing legal notices and potentially having your LLC administratively dissolved.

3File Your Certificate of Organization in Idaho

This is the step that officially creates your LLC. You will file a certificate of organization with the Idaho Secretary of State. Idaho offers both online and mail filing.

Your certificate of organization must include:

  • LLC name (with “LLC” or equivalent designator)
  • Registered agent name and physical address in Idaho
  • Mailing address of the LLC
  • Name and address of at least one member or manager
  • Whether the LLC is member-managed or manager-managed
  • Organizer’s name and signature
Filing Method Fee Processing
Online $100 5-7 business days
Mail $120 7-10 business days
Expedited (online or mail) $140 online / $160 mail 8 business hours

Online filing is the fastest and cheapest option. If you choose to file by mail, download the form and send it with a check or money order to:

4Get an EIN for Your Idaho LLC

An Employer Identification Number (EIN) is a federal tax ID for your business. You need one if your LLC has more than one member, has employees, or will open a business bank account (which is essentially every LLC).

Apply for free directly on the IRS website. The online application takes about 5 minutes, and you receive your EIN immediately upon completion.

5Create an Operating Agreement for Your Idaho LLC

Idaho does not legally require an operating agreement, but operating without one is a risk you should not take. This internal document defines how your LLC is owned, managed, and operated. Without it, Idaho’s default LLC laws will govern your business, and those defaults may not match what you and your co-members actually agreed to.

Your operating agreement should cover:

  • Ownership percentages and capital contributions
  • Profit and loss distribution
  • Member voting rights and decision-making procedures
  • Management structure (member-managed vs. manager-managed)
  • Rules for adding or removing members
  • Procedures for dissolution

Even single-member LLCs benefit from an operating agreement. It reinforces the separation between you and your LLC, which is critical for maintaining liability protection.

It is not required by Idaho law, but it is strongly recommended. An operating agreement protects you in disputes, clarifies member expectations, and strengthens the legal separation between you and your LLC. Banks may also ask to see one when you open a business account.

6Open a Business Bank Account

A dedicated business bank account keeps your personal and LLC finances separate. This separation is essential for maintaining your limited liability protection. If you mix personal and business funds, a court could “pierce the veil” and hold you personally liable for business debts.

Bring the following to the bank:

  • Your filed certificate of organization
  • Your EIN confirmation letter
  • Your operating agreement
  • A government-issued photo ID

How Does Idaho Compare

Idaho Filing Fee

$100

National Average

Idaho’s formation fee is $27 below the national average, and when you factor in the $0 annual report, ongoing costs are among the lowest in the country.

Idaho LLC Taxes

State Income Tax

Idaho has a state income tax. Your LLC itself does not pay income tax at the entity level by default. Instead, profits pass through to the members, who report them on their personal Idaho state income tax returns.

Single-member LLCs are treated as disregarded entities (taxed like sole proprietorships). Multi-member LLCs are taxed as partnerships. Both follow the federal default classification unless you elect otherwise with the IRS (for example, electing S-corp or C-corp taxation).

Franchise Tax

Idaho does not impose a franchise tax or privilege tax on LLCs.

Sales Tax

Idaho’s state sales tax rate is 6%. If your LLC sells taxable goods or certain services, you will need to register for a sales tax permit with the Idaho State Tax Commission and collect sales tax from customers.

Self-Employment Tax

LLC members who actively participate in the business are subject to federal self-employment tax (15.3%) on their share of profits. This applies regardless of whether you actually distribute the profits to yourself.

By default, Idaho LLCs are pass-through entities. Single-member LLCs are taxed as sole proprietorships, and multi-member LLCs are taxed as partnerships. Profits pass through to members who report them on their Idaho personal income tax returns. There is no franchise tax. You can elect S-corp or C-corp taxation with the IRS if a different structure is more advantageous.

After Forming Your Idaho LLC

Annual Reports

Idaho requires every LLC to file an annual report. The filing fee is $0. Your report is due by the last day of the anniversary month of your LLC’s formation. For example, if you formed your LLC on March 15, your annual report is due by March 31 each year.

File your annual report online through the Idaho Secretary of State business portal. There is no late fee, but if you fail to file within 60 days of the due date, the state may administratively dissolve your LLC.

BOI Reporting

As of March 2025, FinCEN issued an interim final rule exempting all domestic reporting companies from the Beneficial Ownership Information (BOI) reporting requirement. You do not need to file a BOI report for your Idaho LLC.

Business Licenses and Permits

Idaho does not require a general state business license. However, your city or county may require local business licenses or permits. Certain industries (such as construction, food service, and healthcare) have their own state-level licensing requirements. Check with your local jurisdiction and the Idaho business resources page to determine what applies to your specific business.

Yes, but the filing fee is $0. Your annual report is due by the last day of the month your LLC was originally formed. If you miss the deadline by more than 60 days, Idaho may administratively dissolve your LLC, so set a calendar reminder even though the filing is free.

Dissolving an Idaho LLC

If you need to close your LLC, you must file articles of dissolution with the Idaho Secretary of State. The filing fee is $0.

Before filing, make sure you:

  • Settle any outstanding debts and obligations
  • Distribute remaining assets to members
  • File final state and federal tax returns
  • Cancel any business licenses or permits

If your LLC has been administratively dissolved (for failing to file annual reports, for example), you can apply for reinstatement. The reinstatement fee is $30, plus you will need to file any overdue annual reports.

An Idaho LLC does not expire on its own. It exists indefinitely unless you voluntarily dissolve it or the state administratively dissolves it for failure to file annual reports. To close your LLC, you must file articles of dissolution with the Secretary of State at no cost.
