The Idaho agent, in order

  1. Stage 1

    Begin with the rule

    Every LLC must name a registered agent with an in-state street address.

    Check it yourself: legislature.idaho.gov, seen in October 2026

  2. Stage 2

    Find out who can serve

    An Idaho resident, or a business entity authorized to do business in Idaho. An assumed business name (DBA) cannot serve. Legal basis: Idaho Code § 30-21-404.

  3. Stage 3

    The address rule

    The address has to be a physical street address in Idaho. P.O. boxes and commercial mailboxes are not accepted.

    Each of our picks supplies a Idaho office address.

  4. Stage 4

    Decide who takes the role

    Owners who meet the tests can name themselves, and for the rest the recommended agents start at $99 to $149 each year.

  5. Stage 5

    Put the agent on the state's record

    the Idaho Secretary of State is where the agent gets recorded, and where any later change goes too.

    Check it yourself: legislature.idaho.gov, seen in October 2026

  6. Stage 6

    Update when something changes

    Budget for the annual report at no cost every year, due last day of the entity's anniversary month. Notices about it arrive through the registered agent.

Why Mainstay Filing is first

Work taken off your desk settled first place in Idaho. It is 32% of the score, and the rest comes from three-year bill, year-two price, fit for where you operate and honest pricing.

A single agent for every state topped the one-state plan.

What founders ask

Is a registered agent required in Idaho?

Yes. Every LLC must name a registered agent with an in-state street address.

Can I be my own registered agent?

You can, once you clear the who-qualifies and address rules in stages 2 and 3.

Can I change my registered agent later?

Yes; the Idaho Secretary of State takes change filings, and stage 5 says what to send.

What does a registered agent cost in Idaho?

The agents we recommend charge $99 to $149 a year.

What does the LLC pay the state each year?

No fee for the annual report.

Which registered agent would you choose?

Phone Mainstay Filing, because one annual fee of $149 follows the company when it expands, and renewal stays $149. After that come ID Registered Agent.org and Idaho Registered Agent.co.
