Starting an S corporation in Iowa could be a game-changer for your business, especially when it comes to managing taxes more efficiently. Opting for S corp status is a tax decision that allows businesses, including limited liability companies (LLCs), to enjoy significant tax savings. This is particularly beneficial in Iowa, where savvy tax planning can make a big difference.

For LLC owners, shifting to an S corp model can be a smart move. Typically, income from an LLC is subject to self-employment taxes, but if your business operates as an S corp, you can draw a salary for the work you do. The best part? You only pay self-employment taxes on that salary. Any additional profits you take home as dividends aren’t subject to these taxes, potentially keeping more money in your pocket.

This guide will examine how you can start an S corp in Iowa, exploring the tax benefits this status can offer and guiding you through the steps to make this change, all while helping ensure your business stays on the right side of tax laws.

S Corporation Requirements and Limitations

Although it has many positive aspects, declaring your company as an Iowa S Corp may not be the right decision for you. You need to understand the limitations, restrictions, and requirements of an S Corp and decide if it fits within the plans for your business. To take advantage of S Corp status, your company must:

  • Be a domestic corporation or other eligible business
  • Have only certain kinds of corporate shareholders, including individuals, estates, exempt organizations, and certain trusts, but not partnerships, corporations, or non-resident immigrants
  • Have no more than 100 corporation shareholders
  • Have no more than one class of stock
  • Not be an ineligible corporation, such as an insurance company, international sales corporation, or a certain kind of financial institution

There are also timing requirements for filing for S Corp status for already existing Iowa corporations and LLCs. The IRS Form 2553 must be filed no more than 2 months and 15 days after the beginning of the tax year the election is to take effect. The other filing option is that it can be filed at any time during the tax year preceding the tax year it is to take effect.

What to know before creating an S Corporation in Iowa

You have to look carefully at the requirements of an S Corp before you decide to file form 2553. It’s important to file Form 2553 immediately when you first apply for an EIN because the IRS will automatically designate your business as a C Corporation if there’s no Form 2553 filing. Being designated as a C Corp tax filing status will require your company to file taxes at the corporate as well as the individual level. In other words, C Corp status opens you up to double taxation.

What’s the difference between an S Corporation and a C Corporation?

Both S Corp and C Corp are tax designations created by the IRS. The S Corp designation has tax advantages, but there are limitations on the class of stocks and stockholders, along with other restrictions. C Corp does not allow for pass-through taxation, but there are no restrictions on the issuance of stock in the company.

Can LLCs choose an S Corporation election?

Yes! There are benefits for an LLC to have S corporation status, above and beyond the pass-through taxation that LLCs already have. If you have an existing Iowa LLC, you should still change its tax status to an S Corp because there are still tax savings an LLC can take advantage of with an S Corp designation.

File Form 2553 to Turn Business into an S Corporation

This simple but important task can be done when you request an Employer Identification Number (EIN) from the IRS. This number is sometimes also known as a federal tax identification number, or FEIN. Your EIN identifies your company to the IRS, and is typically also needed to open a business bank account.

You have to Form 2553 with the IRS to designate your company as an Iowa S Corporation. This task can be done when you obtain your EIN from the IRS, or you can have us obtain an EIN for you.

Once this form is filed, then you can take advantage of all of the benefits of having an Iowa S Corp. Note that if you start your business as an LLC, you first need to file Form 8832 to give your business corporation status, then you can file Form 2553 for S Corporation status. 

Weighing the pros and cons of creating an Iowa S Corporation

 Knowing that an S Corp tax designation isn’t for everyone, we want to point out the pros and cons of going down this road. This will better help you decide whether to make the designation with the IRS.


The positives about having an Iowa S Corporation are the following:

  • You receive all of the personal asset protection that Iowa C corporations and LLCs offer.
  • You avoid double taxation of business profits due to pass-through taxation and income.
  • You are also allowed to be more flexible with income designation, which can ultimately save you more on income tax payments.

It’s pretty easy to file Form 2553 with the IRS to establish your S Corp status if you decide it’s the best course to take with your Iowa company.


Certain restrictions and requirements may lead you to decide that the restrictions of an S Corp aren’t the right fit for your company:

  • There can be only one class of stock offered, so all stockholders are treated the same.
  • There is a limited number of stocks that can be offered.
  • There is more extensive IRS oversight.
  • There are more stringent eligibility requirements.

Making the decision to use the S Corp designation is an important one and you may need the advice of a tax or legal professional to help you make the best choice.

Iowa S Corp FAQs

  • S Corporations are basically small business corporations that have limited corporation shareholders but aren’t subject to corporate double taxation.

  • There are many benefits to an S Corp designation status. The most important is allowing for pass-through income to prevent double taxation of your company’s income.

  • Choosing a name for your business is one of the most important first steps in starting your business in Iowa. Choose a name that both complies with state laws (depending on the entity you’re forming) and is easy for people to identify with your business’s purpose.

  • It is not necessary for you to identify the tax filing status of your company to the general public. Instead, you identify your LLC as an S Corporation by filing the proper documents and tax returns at the state and federal levels.

  • rnThere’s no corporate tax rate for Iowa S corporations. Instead, shareholders pay income tax on company profits when they file their individual tax return. In other words, income from your business is passed through to the owners of S Corps, who then pay personal income tax on the company’s profits. However, tax issues can become complicated, and you should always have a tax professional review your tax filings.
