S Corporation Restrictions
S corps have several restrictions, such as being limited to one class of stock and 100 shareholders. Read our What Is an S Corporation guide for full details.
Are S Corp Tax Advantages Right for You?
An S corporation is a tax designation that can be elected by an LLC or corporation. With an S corp, business owners are considered employees of the company and must receive a reasonable salary. Since all S corps technically have employees, the s corp must run payroll.
In order to benefit from an Iowa S corp tax designation, your business needs to make enough money to offset payroll expenses. Furthermore, S corps are beneficial for business owners who take large distributions in addition to their salary.
To learn more about the tax advantages of an S corp, read our LLC vs. S corp guide and take a look at our S corp tax calculator.
Businesses that elect S corp status will need to hire payroll and accounting services.
How to Form an Iowa S Corp
There are two main ways to start an S corp:

Step 1: Name Your LLC
Choosing a company name is the first and most important step in starting your LLC in Iowa.
Be sure to choose a name that complies with Iowa naming requirements and is easily searchable by potential clients.
1. Follow the naming guidelines for an Iowa LLC:
Your name must contain one of the following terms or abbreviations: limited liability company, limited company, L. L. C., LLC, L. C., or LC. “Limited” may be abbreviated as “Ltd.,” and “company” may be abbreviated as “Co.”
Your name cannot include words that could confuse your LLC with a government agency (FBI, Treasury, State Department, etc.).
Certain restricted words (e.g. Bank, Attorney, University) may require additional paperwork and a licensed individual to be part of your LLC.
Your name must be distinguishable from any existing business in the state. This includes Iowa reserved names.
You can also read the Iowa state statute about LLC naming guidelines for more information.
2. Is the name available in Iowa? You can use the business entities search on the Iowa Secretary of State website to see if your desired LLC name is available.
3. Is the URL available? We recommend checking to see if your business name is available as a web domain. Even if you don't plan to create a business website today, you may want to buy the URL in order to prevent others from acquiring it.

Keep Your Iowa S Corp Compliant
After you elect the S corp tax designation for your Iowa business, you must register for Iowa state business taxes and file a biennial report every two years. It’s important to follow state laws in order to keep your business in good standing.
Iowa S Corp Biennial Report
Your Iowa S corp must file a biennial report with the Iowa Secretary of State. This report informs the state about any changes to your business. Your biennial report is due by April 1 every other year. If you formed your business in an even-numbered year, for example, you must file this report in every even-numbered year.
There’s a fee to file this report and, even if your business isn’t profitable, the state still requires you to file it with the Iowa Secretary of State. Failure to file may result in the state dissolving your business.
Visit our step-by-step Iowa Biennial Report guide for more information.
Iowa S Corp Taxes
S corporations benefit from pass-through taxation, meaning the business’s profits pass-through to S corp owners’ individual tax returns. S corp owners make money from their reasonable salary and distributions, and Iowa S corp owners can expect to pay the following taxes:
Federal Self-Employment Taxes
Self-employment taxes cover social security and medicare. The self-employment tax rate is 15.3%, and money you take as salary will be subjected to the self-employment tax. However, distributions are not subjected to this tax.
Federal Income Taxes
Your federal income taxes will depend on your tax bracket, and the cutoffs for individual tax brackets as well as the percent owed will change each year. Both your salary and distributions are subjected to federal income tax.
Iowa Income Taxes
Iowa’s state income tax ranges from 0.3% to 8.53%, depending on your annual income. In addition, some local jurisdictions impose their own income tax.
While Iowa’s graduated tax rate isn’t excessive, it’s not low when compared to other states. Some states have no income tax while others have an income tax rate that exceeds 10%.
Register for Iowa Business Taxes
In order to pay Iowa business taxes, you must register with the Iowa Department of Revenue.
Register for Iowa Sales Tax
You’ll also need to register with the Iowa Department of Revenue to receive a sales tax permit and tax ID number. Visit the Iowa Department of Revenue website to learn more.
Iowa Sales and Use Tax
Iowa has a statewide 6% sales tax. Many local jurisdictions also impose an additional sales tax, but the state caps local sales taxes at 1%.
Additional State Taxes
Depending on your business’s industry, number of employees, and location, you may owe additional state taxes to the Iowa Department of Revenue. Iowa business owners may have to pay some of the following taxes and fees:
- Contractor Registration Fee
- Fuel Tax
- Hotel and Motel Tax
- Estate Tax

Start an Iowa S Corp FAQ
What is an S corp?
An S corporation (S corp) is a tax designation that an LLC or a corporation can elect.
Are taxes for LLCs and S corps the same?
No. The default taxes for an LLC and taxes for an S corp are not the same.
With an S corp, owners pay personal income tax and self-employment tax on a predetermined salary. They may then withdraw any remaining profits from the business as a “distribution,” which isn’t subject to self-employment tax.
With an LLC, all company profits pass through to the owners’ personal tax returns, and then the owners must pay personal income tax and self-employment tax on the entire amount.
Both LLCs and S corps benefit from a provision in the Tax Cuts and Jobs Act of 2017 that allows qualifying owners of pass-through entities to deduct 20% of qualified business income (QBI) from their tax returns. However, for S corps, the deduction doesn’t apply to profits paid out as wages.
What is a reasonable salary for an S corp?
S corp owners are required to earn a “reasonable” salary, which basically means a fair market rate based on the individual’s qualifications as well as their duties and responsibilities at the company. The purpose of this requirement is to prevent S corp owners from paying themselves an artificially low salary in order to pay less self-employment tax.
What is a distribution?
A distribution is a dividend that a shareholder/owner can take from the business profits that remain after a company pays all of its employee salaries. Shareholders must pay personal income tax on distributions, but distributions aren’t subject to self-employment tax.
Can I still use my DBA name if I elect to be an S corp?
LLCs and corporations that operate under a “doing business as” (DBA) name can choose the S corp election.
Do I have to file an Iowa annual report each year?
No. Unlike most other states, Iowa requires businesses to file a biennial report. This means you must file a report once every two years. Your biennial report will contain the same information as any other state’s annual report. It serves a similar purpose, but is just filed less frequently.
Should I choose to register my S corp in Iowa?
In general, it’s often best to form your business in the state where you plan to operate. If you live and operate your business in the state of Iowa, then it’s likely the best place for you to elect S corp status. Just like with any other state, you’ll need to register your business for state taxes.
