How to Register a Business in Kansas: Formation, EIN, and Taxes

To register a business in Kansas, you file formation documents with the Kansas Secretary of State, get a federal Employer Identification Number from the IRS, and register for state taxes with the Kansas Department of Revenue. The Secretary of State filing runs $85 for a for-profit corporation filed online or $160 for an LLC, and the full sequence of registrations usually takes a few weeks once you account for state processing and the follow-up accounts you’ll need before you can legally operate.

Pick Your Entity Type First

Your structure drives which form you file, what it costs, and how much personal liability you carry. The common choices in Kansas:

  • Limited Liability Company (LLC). Flexible management, pass-through taxation by default, and personal liability protection for members. Most small businesses start here.
  • For-Profit Corporation. A more formal structure with shareholders, a board, and officers. Required if you plan to issue stock.
  • Limited Partnership. At least one general partner with unlimited liability and one or more limited partners capped at their investment.
  • General Partnership. Two or more people sharing profits and liability. No formation filing needed, but no liability protection either.

Kansas LLCs can carry on nearly any lawful business, with narrow exceptions for insurance underwriting and banking as defined in K.S.A. 9-702.1Justia. Kansas Code 17-7668 – Nature of Business Permitted; Powers Licensed professionals like lawyers, doctors, and accountants can operate through a professional LLC, provided at least one member holds the relevant Kansas license. Pick your structure before you touch any paperwork, because the Secretary of State will reject a filing submitted on the wrong entity-specific form.

Lock Down a Name and a Resident Agent

Your name must be distinguishable from every other entity on file with the Secretary of State, including names cancelled or forfeited within the past year.2Kansas State Legislature. Kansas Code 17-7918 – Business Entity Standard Treatment Act Search the Secretary of State’s business database first. If your name conflicts, the filing is rejected and the processing fee is gone. LLCs need a formation word or abbreviation like “LLC” or “Limited Liability Company” in the name. Corporations typically need “Inc.,” “Co.,” or “Corporation.”

Every Kansas entity must also maintain a resident agent inside the state.3Justia. Kansas Code 17-7925 – Resident Agent; Requirement to Maintain; References in Documents Kansas calls them “resident agents” rather than “registered agents,” but the job is the same: accept legal documents and official state mail for your business. The agent can be a Kansas resident, a domestic business entity, or the company itself, and must have a physical Kansas street address. P.O. boxes don’t qualify. You list the agent on your formation documents, and you need to file an update if you ever switch. Letting the agent lapse is one of the fastest routes to a forfeited entity, because the state has no way to reach you.

File Formation Documents With the Secretary of State

The form you file depends on the entity. For a standard LLC, that’s the Articles of Organization, Form DL.4Kansas Secretary of State. Articles of Organization Domestic (Kansas) Limited Liability Company DL For a for-profit corporation, it’s the Articles of Incorporation, Form AI.5Kansas Secretary of State. Articles of Incorporation Domestic (Kansas) Corporation AI Series LLCs use Form LAO, and professional LLCs use Form PDL.6Kansas Secretary of State. Articles of Organization Domestic (Kansas) Limited Liability Company That May Create Series LAO

The LLC form asks for your company name, resident agent, and whether members or designated managers will run it. The corporate form asks for the business purpose and the total number of authorized shares. Both require a signature from the organizer or incorporator certifying the information.

Fees and Where to Send It

File online at sos.ks.gov or mail your documents and payment to the Kansas Secretary of State, Memorial Hall, 1st Floor, 120 SW 10th Avenue, Topeka, KS 66612-1594. Processing takes a few business days, and your business legally exists only once the state accepts the filing, not when you submit it.

Get a Federal EIN

Almost every business needs an Employer Identification Number from the IRS, even without employees. Banks require one to open a business account, and you’ll need it for federal tax filings. The application is free, and applying online through the IRS website issues the number immediately.7Internal Revenue Service. Get an Employer Identification Number

You’ll need the Social Security number or ITIN of the “responsible party,” meaning the person who controls or directs the entity. For a single-member LLC, that’s typically the owner. For a corporation, usually a principal officer. The IRS online tool walks you through it. Mail or fax applications on Form SS-4 work too, but those take four to six weeks.

Register for Kansas State Taxes

Once your entity exists on paper, register with the Kansas Department of Revenue for any applicable state taxes. Use Form CR-16, the Business Tax Application, filed online through the Kansas Customer Service Center or on paper.8Kansas Department of Revenue. Business Registration

The CR-16 covers several tax types at once. If you sell tangible goods or taxable services, you register for the state retailers’ sales tax, currently 6.5 percent plus any local tax that applies.9Kansas Department of Revenue. Sales (Retailers) If you have employees, you also register for withholding tax through the same form. You’ll need your NAICS code (a six-digit industry classification) and your anticipated start date. Don’t delay this one. Kansas penalties for late filing start at 1 percent of unpaid tax per month and run up to 24 percent.10Kansas Legislature. Kansas Code 79-3228 – Penalties and Interest

If You’re Hiring Employees

Formation and tax registration are only the start if you’ll have employees. Two more accounts need to be in place before your first payroll.

Unemployment Insurance

Kansas employers must register with the Kansas Department of Labor for an unemployment insurance tax account. The department’s Employer Self Service Portal handles the registration and the quarterly wage reports and payments going forward.11Kansas Department of Labor. Employer Services

Workers’ Compensation Insurance

Kansas requires most employers with gross annual payroll above $20,000 to carry workers’ compensation insurance and to report any alleged workplace injuries.12Kansas Department of Labor. Workers Compensation Division Sole proprietors, LLC members, and partners can opt out of covering themselves, and certain agricultural employers and independent-contractor realtors are also excluded, but every other employee must be covered once you cross the payroll threshold. Coverage comes from a private insurer, or from an approved self-insurance plan if you qualify.

Check Local Licensing

Kansas has no general state business license, so the registration you did with the Secretary of State does not satisfy any city or county requirements. Many municipalities require a general business license for operating within their borders, and specific industries carry their own local permits: restaurants need health department approval, contractors may need local trade permits, and home-based businesses sometimes need zoning or home-occupation approval. Contact the city or county clerk where you’ll operate. These rules vary widely across Kansas, and the Secretary of State does not handle any of it.

Internal Documents You Should Have

Kansas does not require you to file an LLC operating agreement or corporate bylaws with the state, but you still want them in writing. An LLC operating agreement sets each member’s ownership percentage, how profits and losses split, what happens when someone leaves, and who decides what. Without one, Kansas default statutes fill in the gaps, and those defaults rarely match what the owners actually wanted. Corporations need bylaws covering board size, officer roles, meetings, and voting, typically adopted at the first organizational meeting. Courts look at these documents when deciding whether an entity’s liability protection holds up.

Keep the Entity in Good Standing

Most Kansas business entities must file a biennial Information Report with the Secretary of State every two years. For-profit entities, including LLCs and corporations, generally file by April 15 in their designated filing year. The report updates your current address, resident agent, and officers or members. The fee is $100 online or $110 by paper. Kansas does not send a reminder, and missing the report leads to administrative penalties and eventually forfeiture of your entity’s good standing, often discovered only when you try to renew a license or close a deal.

Beneficial Ownership Reporting

If you’ve read about the Corporate Transparency Act and its FinCEN beneficial ownership report, here is the current status: under an interim final rule published in March 2025, all entities formed in the United States are exempt from beneficial ownership reporting.13FinCEN.gov. Beneficial Ownership Information Reporting The requirement now applies only to foreign entities registered to do business in a U.S. state. Unless that rule changes, domestic Kansas entities do not need to file a BOI report.
