How to File

1

Choose a Corporate Name

30 minutes

2

Appoint a Registered Agent

Designate a registered agent with a physical street address in Iowa who is available during normal business hours to receive legal and official documents on behalf of the corporation. The agent can be an individual Iowa resident or a registered commercial agent service.

30 minutes

3

File Articles of Incorporation

Prepare and file the Articles of Incorporation with the Iowa Secretary of State, either online through the Fast Track Filing system or by mail. The articles must include the corporate name, registered agent information, number of authorized shares, and incorporator details.

1-2 hours

4

Create Corporate Bylaws

Draft corporate bylaws that govern the internal operations of the corporation, including provisions for shareholder meetings, board of directors' roles, officer duties, and stock issuance. While not filed with the state, bylaws are legally important and should be adopted at the organizational meeting.

2-4 hours

What's Next After Filing

Once your S-Corp is officially formed, you'll want to complete these important steps:

  • Hold an Organizational MeetingConduct the initial organizational meeting of the board of directors to adopt the bylaws, elect officers, authorize the issuance of stock, and address other foundational corporate matters. Document all actions taken with formal minutes.
  • Obtain an EIN and Elect S-Corp StatusApply for a federal Employer Identification Number (EIN) from the IRS at no cost, then file IRS Form 2553 (Election by a Small Business Corporation) to elect S-Corporation tax treatment. The Form 2553 must be filed no later than two months and 15 days after the beginning of the tax year the election is to take effect.
  • Register for Iowa Taxes and Obtain LicensesRegister with the Iowa Department of Revenue for applicable state taxes, including income tax withholding if you have employees, and obtain any required state or local business licenses or permits relevant to your industry and location.

Advantages

  • Pass-through taxation avoids federal corporate double taxation, with income and losses flowing directly to shareholders' personal tax returns
  • Shareholders who are active employees can reduce self-employment tax liability by splitting compensation between reasonable salary and distributions
  • Provides limited liability protection, shielding personal assets of shareholders from business debts and legal judgments
  • Iowa does not impose an entity-level income tax on S-Corporations, meaning only shareholders pay Iowa individual income tax on their share of earnings

Considerations

  • S-Corporation election comes with strict IRS eligibility requirements, including a maximum of 100 shareholders, only one class of stock, and all shareholders must be U.S. citizens or permanent residents
  • More administrative burden than an LLC, including requirements for bylaws, formal board meetings, corporate minutes, and stricter recordkeeping
  • Iowa's Biennial Report filing requirement and ongoing state compliance obligations add administrative responsibilities and costs compared to simpler structures

Annual Obligations

Annual Report Fee:$60
Report Due:April 1
Iowa S-Corporations must file a Biennial Report (every two years) with the Iowa Secretary of State by April 1 of odd-numbered years, with a $60 filing fee ($45 if filed online). Additionally, Iowa S-Corporations must file an Iowa Income Tax Return for S-Corporations (Form IA 1120S) annually. Shareholders report their pro-rata share of income on their individual Iowa income tax returns. Iowa does not impose a separate franchise or corporate income tax on S-Corporations at the entity level, but the pass-through income is taxable to individual shareholders at Iowa's individual income tax rates.
