Starting an S corporation in Idaho could be a savvy move for business owners looking to tap into tax savings. Recognized by the IRS under Subchapter S of the Internal Revenue Code, an S corp status allows businesses to pass income directly to shareholders, avoiding the double taxation often seen with C corporations. This setup can be particularly beneficial for Idaho-based limited liability company (LLC) owners, as it opens the door to potential self-employment tax savings. By electing S corp status, LLCs can differentiate between salary and distribution earnings, with only the salary portion subject to self-employment taxes.

This article will guide you through the essentials of converting to an S corp in Idaho, highlighting the steps, benefits, and considerations to maximize your business’s tax efficiency.

What to know before creating an S Corporation in Idaho 

 To convert your LLC or corporation to an S Corp, it needs to meet certain requirements. Specifically, the entity:

  • May not have more than 100 owners
  • Must be owned by U.S. residents, trusts, or estates
  • Must have only one class of stock
  • May not be an ineligible entity such as a financial institution or insurance company

You may be wondering what’s so special about an S Corp and why you’d want to convert an LLC or a regular corporation to an Idaho S Corp.

What is the difference between an Idaho S Corp and a C Corp?

The primary difference between an S Corporation in Idaho and a C corp is how the corporation is taxed. In a typical C Corp, the corporation itself pays corporate income taxes on income earned by the business. When dividends are issued to shareholders to distribute these profits, the shareholders themselves will pay taxes as well. This can create lead to double taxation.

File Form 2553 to apply for S Corp status

Complete and submit the form to apply for S corporation tax election. Once your LLC or corporation formation is approved by Idaho, you need to file Form 2553, Election by a Small Business Corporation, with the IRS to get S corp status. 

The Internal Revenue Service requires you to complete and file your Form 2553: 

  • Within 75 days of forming your LLC or C corporation, or no more than 75 days after the beginning of the tax year in which the election is to take effect


  • At any time during the tax year preceding the tax year the election is to take effect.

One note for limited liability companies wanting to file as an S corp: If your LLC is past the 75-day election deadline, you’ll also need to file Form 8832, Entity Classification Election, to elect to be taxed as a corporation. Then you file both Form 8832 and Form 2553 together via USPS-certified mail. 

Every one of the members or shareholders must sign the consent statement portion of the form. The IRS website has more information on how to file Form 2553.
