How to register your Maine LLC in Idaho

1

Check name availability in Idaho

Before filing, verify that your LLC name (or a distinguishable variation) is available in Idaho. If your exact name is already taken, you may need to register under a fictitious or assumed name.

Check the Idaho Secretary of State website for name availability search.

2

Get a Certificate of Existence from Maine

Idaho requires a Certificate of Existence from Maine to prove your LLC is in good standing. The fee is $30. No expiration printed; foreign-state applications typically require dating within 30-90 days.

3

File the Certificate of Authority in Idaho

Submit your application along with the Certificate of Existence and the $100 filing fee. Processing time is 5-7 business days. Expedited processing available for $20.

Idaho consolidated its business entity laws into the Idaho Uniform Business Organizations Code (Title 30, Chapter 21), which uses unified provisions for foreign entities rather than entity-specific statutes. Section 30-21-505 lists activities that do not constitute 'doing business' for foreign LLCs and other registered foreign entities. Idaho uses 'doing business' rather than 'transacting business.'
