Things to Know Before You Form an S-Corp in Idaho

An S-corp isn’t a business structure but a tax status. First, you’ll form a corporation or an LLC, then elect an S-corp status with the IRS to access its tax benefits.Here are some key things you should know before starting an S-corp in Idaho.

  • You’ll need to file a Certificate of Organization to form an LLC or an Article of Incorporation to form a corporation in Idaho. The fee is $100 for online filings and $120 for paper filings, with an option for same-day filing at $100 more.
  • An S-corp in Idaho doesn’t pay a franchise tax. Instead, each shareholder pays a $10 business tax each year. You also have to file Idaho Form 41S to report corporate income tax, including federal K-1s for each shareholder.
  • S-corps in Idaho are required to file an annual report with the Idaho Secretary of State to remain in good standing, which costs $0. This requirement applies to all entities registered to do business in the state, including nonprofits.
  • Idaho requires S-corps to keep a registered agent with a physical Idaho street address. You can be your own registered agent or use a business authorized in Idaho. This agent accepts legal papers on behalf of your S-corp in Idaho.

Starting an S-corp in Idaho is straightforward. It’s online and there are easy steps to follow. There are also expedited filing so you can start your business quickly.

1. Decide on Your Business Entity First and Foremost

You can’t just form an S-corp in Idaho. First, you need a legal business structure, either a corporation or a limited liability company. Both can opt for S-corporation election status, but they have different rules for operations.

If you choose a corporation, you’ll have more formal requirements, like shareholder meetings and a board of directors. If you choose an LLC, you’ll usually have fewer formalities, but you must still meet IRS requirements to qualify for S Corp taxation.

Choose a Relevant and Unique Business Name

2. Choose a Relevant and Unique Business Name

The first step is to pick a trade name that suits your business. Your name should be unique but easy to remember. Think of a name that tells people what you do while still being professional. A good business name can help you stand out from others.

Once you have a name in mind for your S-corp in Idaho, check Idaho’s Secretary of State website to see if it’s available. If the name is already taken, you’ll need to try a new one. Take your time because this step sets the tone for your business.

3. Reserve Your Business Name with the State

After you decide on a name, you can reserve it if you’re not registering the name right away. Idaho lets you hold your chosen name for up to four months. This gives you time to finish your paperwork without worrying that someone else will use it.

The process to reserve a business name is simple. You’ll need to file an application to reserve the name with the Secretary of State, which costs $20 for online filing. With this, you can take your time to prepare the necessary business documents.

Choose an Official Registered Agent in Idaho

4. Choose an Official Registered Agent in Idaho

Every business is required to have a registered agent, someone with a physical address in the state who can receive legal documents. Your business could lose its good standing and miss important notices and deadlines if you don’t have an agent.

Many entrepreneurs use professional services for this, but you can also appoint yourself if you live in Idaho. Just be prepared for your address to be public record. Having a registered agent helps ensure your S-corp in Idaho stays compliant.

5. Draft an Operating Agreement or Corporate Bylaws

Next, create an operating agreement if you form an LLC or bylaws if you form a corporation. These documents explain how your Idaho business will be managed. Even though Idaho does not require them by law, having them helps add structure.

If your S-corp in Idaho has multiple shareholders, this step is important. With this document, you can outline details about what happens if an owner leaves and how new members are added. Documenting these rules prevents future conflicts.

File Your Certificate of Organization or Article of Incorporation

6. File Your Certificate of Organization or Article of Incorporation

To officially register your business in Idaho, you’ll need to file either a Certificate of Organization for an LLC or Articles of Incorporation for a corporation. This makes your business legal in the eyes of the state. The forms can be filed online or by mail.

Online filing for an LLC and a Corp with the Secretary of State both costs $100, while paper filing costs $120. To get your business formed quickly, you can choose the expedited service or same-day processing at $40 and $100 more, respectively.

7. Apply for a Tax ID or Employer Identification No.

One of the final steps in setting up your S-corp in Idaho is getting a Tax Identification Number (TIN), also known as an Employer Identification Number (EIN). This number is usually issued by the IRS and is used to identify your business for tax purposes.

While you can apply for an EIN through the IRS website, many businesses prefer using a formation service like Inc Authority that includes tax assistance. They take care of the application and ensure your business is set up correctly for tax filings.

File the IRS Form 2553 to Elect the S-Corp Status

8. File the IRS Form 2553 to Elect the S-Corp Status

After you have obtained your EIN, the next step is to file IRS Form 2553 to elect S-corp tax status. This form tells the IRS that you want your business to be given tax treatment as an S-corporation instead of a domestic corporation or LLC.

To do this, you’ll need to provide details like your company’s EIN, the names of shareholders, and their ownership percentages. It’s important to file within 75 days of forming your business, or you may need to wait until the next tax year to do so.

9. Register Your New S-Corp for Idaho State Taxes

Once you elect S-corp tax status with the IRS for federal tax purposes, you must also review your state-level tax responsibilities in Idaho. While an S-corp in Idaho does not file a state corporate income tax, it may still have other tax obligations.

For instance, if your business sells physical products, you are required to register for a sales tax permit with the Idaho State Tax Commission. This permit allows you to collect and remit the state’s 6% sales tax on taxable goods and services.

Register a DBA if You Need a Fictitious Name

10. Register a DBA if You Need a Fictitious Name

In Idaho, a DBA (Doing Business As) is formally referred to as an “Assumed Business Name”. Registering a DBA allows your S-corp in Idaho to operate under a trade name different from its registered legal name to depict your services.

Idaho law requires that assumed business names be distinguishable from the names of other registered businesses. Check availability on the Secretary of State’s business search tool. Once approved, the DBA name expires after 10 years.

11. Obtain Required Business Licenses and Permits

Unlike some states like Delaware, Nevada, Alabama, and a few others, Idaho does not require a general statewide business license. However, your S-corp in Idaho may need industry-specific permits or licenses depending on where you operate.

If your business involves professional services like consulting, real estate, and others, you may need a professional license from an Idaho regulatory board. If your S-corp in Idaho operates in a regulated field, it’s good to see which permits apply.

Open a Business Bank Account for Your S-Corp

12. Open a Business Bank Account for Your S-Corp

One of the first financial steps for an S-corp in Idaho is establishing a dedicated business bank account. This account keeps your corporate finances separate from your personal funds, which is essential for maintaining liability protection.

To open an account, banks in Idaho typically require your filed Articles of Incorporation or Certificate of Organization, your EIN, and a copy of your operating agreement. Some banks may also ask for a Certificate of Good Standing.

13. Create a Standard Accounting and Bookkeeping System

One of the core responsibilities of managing an S-corp in Idaho is maintaining organized records, and this includes finances, too. Proper bookkeeping helps you track income, expenses, and shareholder distributions, and prepare for tax filings.

Many Idaho businesses use bookkeeping software to maintain organized records. Others hire bookkeepers or accountants to ensure accuracy in financial reporting. Setting up a system will give you a clear picture of your company’s financial health.

Maintain Compliance with State Rules and File Annual Reports

14. Maintain Compliance with State Rules and File Annual Reports

Every corporation, LLC, and nonprofit registered in Idaho must submit an annual report each year to the Idaho Secretary of State. This filing is due by the end of your corporation’s anniversary month each year, and can be submitted online at no cost.

Compliance doesn’t stop with annual reports. Your S-corp must also meet ongoing IRS filing obligations and maintain shareholder records. Regular shareholder meetings should be documented as part of the compliance requirements.
