How to Get an EIN for Your Marketer Business in Kansas (2026)

As a marketer in Kansas, obtaining an Employer Identification Number (EIN) is a crucial step for structuring and legitimizing your business. Whether you're a solo SEO consultant, a PPC manager, or running a full-fledged marketing agency, an EIN is essential for various operational and compliance needs. This guide will walk you through the process of getting an EIN for your marketing business in Kansas in 2026.

What is an EIN?

An Employer Identification Number (EIN) is a unique nine-digit number assigned by the IRS to identify business entities. It's essentially a Social Security number for your business. While not always mandatory, it's often required for opening a business bank account, hiring employees, and various tax-related activities.

How to Apply for an EIN

  1. Determine Your Eligibility: Ensure your marketing business structure requires an EIN. Most LLCs (especially those with employees or multiple members) and corporations need one. Sole proprietorships may need one if they hire employees or operate as a corporation or partnership.
  2. Choose Your Business Structure: Decide on your business structure (LLC, S-Corp, C-Corp, etc.). This choice impacts your tax obligations and the EIN application process. In Kansas, LLCs are popular for their liability protection and pass-through taxation.
  3. Prepare Form SS-4: Complete IRS Form SS-4, Application for Employer Identification Number. You'll need to provide information about your marketing business, such as its legal name, address, responsible party, and the reason for applying.
  4. Submit Your Application: You can apply for an EIN online through the IRS website, by fax, or by mail. The online application is the fastest method and is generally recommended.
  5. Receive Your EIN: If you apply online, you'll typically receive your EIN immediately. If you apply by fax or mail, it can take several weeks. The IRS will send you a confirmation notice (CP 575) with your EIN.
  6. Notify Kansas State Agencies: Inform the Kansas Department of Revenue of your new EIN, especially if you plan to hire employees or collect sales tax. Update your business registration with the Kansas Secretary of State if necessary.
