Kansas EIN: How It Becomes Your Kansas Tax Account Number

Last updated November 1, 2026 · Written by the EIN Registration filing team

There is no Kansas EIN. The IRS issues it on Form SS-4. What Kansas adds comes after it: a Kansas tax account number from the Kansas Department of Revenue once you pay wages, an unemployment insurance account with the Kansas Department of Labor, and a Retailers' Sales Tax Registration Certificate from the Kansas Department of Revenue if you sell taxable goods or services.

After your EIN in Kansas

The Kansas Business Tax Application (Form CR-16, filed online through the KDOR Customer Service Center) covers most business taxes the Department of Revenue administers, and KDOR issues a Certificate of Registration or reporting number for each tax type. Unemployment tax is not part of it; that registration is with the Kansas Department of Labor.

Kansas builds its withholding account number from your federal EIN. It is 15 characters: the tax type 036, then the nine-digit EIN, then F01. The full number, written like 036-XXXXXXXXXF-01, goes in the employer's state ID box on every W-2.

A Kansas sales tax account number follows the same pattern with tax type 004, then your EIN, F and 01, and it is printed on the Retailers' Sales Tax Registration Certificate. A business that is not required to have an EIN gets a number the department creates, starting with a letter instead.

Also on the Kansas list

  • Register with the Kansas Department of Revenue through the KDOR Customer Service Center, whose questionnaire tells the business which state taxes it needs. The department assigns a registration number and issues a Certificate of Registration or reporting number for each tax type, which is posted at the place of business.
  • File the information report with the Secretary of State every two years, by April 15 of each even-numbered or odd-numbered year to match the year the LLC was formed.

What is different about Kansas

  • Kansas replaced its annual report with a biennial information report on January 1, 2024. The reporting year follows the formation year: an LLC formed in an even-numbered year files in even-numbered years, and one formed in an odd-numbered year files in odd-numbered years. A company still unfiled three months after the due date forfeits and cannot file anything else with the Secretary of State until it catches up and is reinstated.
  • A Kansas LLC's information report must name each member who owns 5 percent or more of the capital, with an address where that member can regularly be found. The Secretary of State treats its filings as public record that may be viewable online, so the names of significant owners end up on the public record.
  • Kansas Secretary of State forms, from the information report to a change of resident agent, ask first for the business entity ID the Secretary of State issued and say in the instructions that it is not a tax ID number. The EIN, and any Department of Revenue registration number, do not belong in that box.

Before you apply

The SS-4 must match the Kansas Secretary of State filing; its business entity ID is a state index, not a tax ID.

Kansas EIN questions

How do I get an EIN number in Kansas?

File IRS Form SS-4 after the Kansas Secretary of State approves any formation filing; there is no Kansas EIN application. The Kansas Business Tax Application (Form CR-16, filed online through the KDOR Customer Service Center) covers most business taxes the Department of Revenue administers, and KDOR issues a Certificate of Registration or reporting number for each tax type. Unemployment tax is not part of it; that registration is with the Kansas Department of Labor.

Is there a Kansas EIN or state tax ID number?

No; only the IRS issues EINs (also called the FEIN or federal tax ID). Kansas's own numbers are the business entity ID from the Kansas Secretary of State, the Kansas tax account number from the Kansas Department of Revenue, and the Retailers' Sales Tax Registration Certificate from the Kansas Department of Revenue.

Is the Kansas tax account number the same as my EIN?

No. The Kansas Department of Revenue assigns it when you register as an employer in KDOR Customer Service Center, and it is 036, then your EIN, then F01. It goes in W-2 box 15; the EIN goes in box b.

Where do I register for Kansas unemployment insurance?

With the Kansas Department of Labor, online through Employer Self Service Portal. The account is separate from the federal EIN, which the registration asks for.

Do I need a Kansas Retailers' Sales Tax Registration Certificate?

Only if you sell what Kansas taxes. The Kansas Department of Revenue issues it through KDOR Customer Service Center, and your returns are filed under its number, not the EIN.
