How to Register a Small Business in Idaho: A Beginner's Guide

Updated: Sep 11, 2022

Are you ready to start your local business in Idaho? You'll first need to register your business with the state of Idaho, which offers several types of business registrations with important legal and tax differences.

This beginner's guide only covers business registration at the state level, not at a local level such as a city or county. However, most cities and counties require a business to register at the state level first before any local business registration can be done, such as with a business license or permit.


Step 1: Choose a Business Structure

To start a small business, you first need to choose a legal business structure which is a government classification for legal and tax purposes. In Idaho, you can structure your business as a:

  • Sole Proprietorship

  • General Partnership

  • Limited Partnership

  • Limited Liability Partnership

  • Limited Liability Company

  • Professional Limited Liability Company*

  • Corporation

  • Professional Service Corporation*

Each business structure has important legal and tax differences that may or may not be optimal for your small business.


*In Idaho, only certain professions can form a Professional Limited Liability Company or a Professional Service Corporation. See the registration form of these business structures for a list of qualified professions, which you can find in Step 3.

Step 2: Check Business Name Availability

Once you have chosen a business structure, the next step is to check if your proposed business name is available in the state of Idaho. You can avoid filing delays or rejection by ensuring your proposed business name is not the same or similar to another registered business name.


Do a quick business name search on the Idaho Secretary of State's website:


Federal Trademark Business Name Search

You should also check the United States Patent and Trademark Office's (USPTO) website for business names registered as federal trademarks. A business name that is registered as a federal trademark gives that business nationwide legal protection from other similar businesses from using that name, even if that business does not do business in Idaho.


Avoid using a business name that is the same or too similar to a business name that is registered as a federal trademark.


Business Name Reservation (Optional)

If your proposed business name is available in Idaho, but you are not sure yet which business structure to choose, the state of Idaho lets you reserve a business name for four months; however, this only applies to certain business structures/entities.


To reserve a business name, you must file an Application for Reservation of Legal Entity Name form and pay a small state filing fee. The form is simple and easy to complete, and you can file this form online.


 

Step 3: File State Paperwork

Once you have selected a business structure and found an available business name, you're ready to make your business official. You can register your business yourself or do what many small business owners do and use a professional online filing service.


Using an online filing service is an excellent option if you find it too complicated to do it yourself or you find it too expensive to hire a local professional to do it for you.


If your file a document yourself, read carefully the instructions on how to properly complete the form. Look out for details such as:

  • Providing a proper address (on some lines, a PO BOX or Personal Mailbox will not be accepted)

  • Providing an eligible registered agent (depending on the business structure)

  • Including certain words or abbreviations in your business name


Sole Proprietorship

The state of Idaho does not require a sole proprietorship to register. However, you may need to obtain a Certificate of Assumed Business Name (ABN) if your business name does not include your legal first and last name.
