1. Registered Agent
Appoint an Idaho resident as your company's agent to receive official paperwork and government correspondence. This can be you or a hired commercial registered agent.

2. Certificate of Organization
To register your business in the form of an LLC, file the Certificate of Organization on the Idaho Secretary of State website. The fee is $100 if submitted online, with an additional $20 fee for a non-electronic form for manual entry.

The key information that the Certificate of Organization in Idaho includes are the name of your business (the name must include the words "Limited Liability Company," "Limited Company," or the abbreviations L.L.C., LLC, or LC), the data of your registered agent, principal office address, name and address of at least one governor of the limited liability company, and the mailing address.

Corporation

Establishing a corporation requires fulfilling various legal and administrative responsibilities. These encompass activities like state registration, creation of corporate bylaws, and the appointment of a board of directors. Given the complexities involved, many businesses that provide services opt for simpler business structures, such as sole proprietorships, partnerships, or limited liability companies (LLCs).

Step 5 of 8

Consider creating an operating agreement

An operating agreement can provide valuable benefits to certain business entities in Idaho, such as Limited Liability Companies, Limited Liability Partnerships, Professional Limited Liability Partnerships, and Professional Limited Liability Companies.

While Idaho does not mandate an operating agreement for LLCs and PLLCs, it is strongly recommended as it helps establish internal structure, ownership rights, and operational procedures. When it comes to LLPs and PLLPs, having an operating agreement is crucial in determining partner rights, profit allocation, and various operational aspects. Additionally, an operating agreement may be necessary in outlining partner roles, profit distribution, decision-making processes, and dissolution procedures.

Step 6 of 8

Apply for Employer Identification Number (EIN)

Employer Identification Number (EIN) is absolutely essential for a variety of important purposes. This individual nine-digit identifier plays a vital role in ensuring accurate tax filing and adherence to tax regulations. Furthermore, it is crucial for efficient management of payroll tax reporting and proper withholding of taxes when employing individuals. Acquiring an EIN is also frequently a prerequisite for establishing a business bank account. 

To apply for an EIN, you must determine your eligibility by having a valid Taxpayer Identification Number (TIN) and being the owner or co-owner of the business. If you meet these requirements, you can complete the application online by visiting the Internal Revenue Service website and following the instructions. There is no fee for obtaining an EIN, and you will receive it immediately upon completion if applying online.

Note that for sole proprietorships without employees the owner may use their Social Security Number (SSN) instead of an EIN.

Step 7 of 8

Obtain licenses & permits

In Idaho, most service businesses need a local business license from their city or county, and some also need state permits or professional licenses. It is recommended to contact the Idaho Secretary of State, local government offices, and relevant agencies to determine the exact licensing and permitting requirements for your specific service business.

Idaho has no general state business license: registering your business with the Idaho Secretary of State is a registration, not a license. Certain service businesses, such as attorneys, architects, construction contractors, event planners, accountants, and therapists, may require professional licenses issued by the respective state licensing boards. If your service business sells goods or certain types of taxable services, you may need to obtain a sales tax permit from the Idaho State Tax Commission.

Many cities in Idaho require service businesses to obtain a local business license, in addition to the state license. The requirements and fees for these licenses vary by city. Moreover, depending on the location and nature of your service business, you may need to obtain zoning permits or approval from the local planning department to ensure compliance with local land-use regulations.
