How to Start an LLC in Idaho (2026)

Q: How much does it cost to start an LLC in Idaho?

The Certificate of Organization costs $100 filed online through SOSBiz. Idaho adds a $20 manual processing charge for typed paper forms, so filing on paper costs $120. Your EIN is free from the IRS, and the annual report carries no state fee, which makes Idaho one of the cheapest states to maintain an LLC in.

Q: When is the Idaho annual report due?

By the close of business on the final day of your anniversary month, meaning the month your LLC became effective, and annually after that. Idaho Code 30-21-213 sets the rule. There is no filing fee, but the report is still mandatory and repeated failure leads to administrative dissolution.

Q: Is the Idaho annual report really free?

Idaho does not charge a state fee for the LLC annual report, which is unusual and welcome. The catch is behavioural: with no invoice and no payment step, it is easy to let the deadline slide. Put the last day of your anniversary month in your calendar as a recurring reminder the day your LLC is approved.

Idaho is inexpensive, quick, and almost entirely online, with a free annual report that still has to be filed on time. Here is the whole process in plain English, written for people starting something real like a courier route.

The free report has a hard deadline Under Idaho Code 30-21-213, your annual report must be received in the office of the secretary of state no later than the close of business on the final day of the applicable month, which is the month your LLC became effective, and then annually after that.

How to start a Idaho LLC in 6 steps

Name it, appoint an Idaho registered agent, file the Certificate of Organization online ($100), write an operating agreement, get a free EIN, then file the free annual report by the end of your anniversary month.

Name your Idaho LLC

The name must be distinguishable from other Idaho entities and include an LLC designator. Search it in the SOSBiz business search before you file, and grab the matching domain while you are there.

Appoint an Idaho registered agent

You need a registered agent with a physical Idaho street address available during business hours. You can be your own if you live in the state, or use a service to keep your home address off the public record. Northwest includes agent service free the first year with their $39 filing.

File the Certificate of Organization

File through SOSBiz, the Idaho Secretary of State online system. The base fee is $100, and Idaho adds $20 for manual entry if you submit a typed paper form, so filing online saves both time and money. All the business forms are here.

Write an operating agreement

Idaho does not require one, but write it anyway. It sets out ownership, management, and who can sign, it backs your liability protection, and banks usually ask for it at account opening. A simple template covers a single-owner courier business.

Get a free EIN from the IRS

Your EIN is free at irs.gov and takes about ten minutes. You need it for the business bank account, contracts, and hiring. Never pay a third-party site for one.

File the annual report by the end of your anniversary month

Idaho requires an annual report with no state fee, filed through SOSBiz. It must be received by the close of business on the last day of your anniversary month. Set the reminder yourself, because a free filing generates no invoice to prompt you.
