State Guide
EIN in Kansas (KS)
How to get an EIN for your Kansas business. The EIN is a federal number from the IRS, identical in every state. Non-residents apply with a passport, no SSN required. $49 Standard. $97 Express.
Getting an EIN in Kansas follows the same federal IRS process as every other state. The EIN is a federal number from the IRS, not a Kansas-specific number. A US resident applies free online at irs.gov in minutes. A non-resident enters a passport number on Form SS-4 Line 7b and faxes it to 855-215-1627. ein.so files for $49 (4-7 business days) or $97 Express (2-3 business days).
Kansas sits at the geographic center of the United States, with Wichita, Overland Park, and Kansas City anchoring its business activity. Founders form Kansas LLCs to serve the agriculture, aviation, logistics, and e-commerce sectors. Every Kansas business that hires staff, opens a bank account, or files US taxes needs an Employer Identification Number (EIN). The EIN is a 9-digit federal tax ID in the format XX-XXXXXXX. The IRS issues it. Kansas does not. This guide explains how both US residents and non-residents get an EIN for a Kansas business, how the federal EIN differs from the Kansas state tax ID, and what to do after approval.

Federal vs State
Is a Kansas EIN Different From a Federal EIN?
No. A Kansas EIN and a federal EIN are the same number. The IRS issues one 9-digit EIN that works in all 50 states. Kansas does not issue a separate EIN. Your federal EIN and your Kansas state tax registration are two different identifiers with two different purposes.
The confusion is common, so here is the clear split. Your federal EIN comes from the IRS through Form SS-4. It handles federal tax filing, payroll reporting, and banking. Your Kansas state tax ID comes from the Kansas Department of Revenue. It handles Kansas sales tax and state withholding.
| Identifier | Issuer | Purpose | How to Get It |
|---|---|---|---|
| Federal EIN | IRS | Federal taxes, banking, payroll | Form SS-4 |
| Kansas state tax ID | Kansas Department of Revenue | Sales tax, state withholding | State registration |
You may need both numbers, depending on what your Kansas business does. A business selling taxable goods in Kansas registers for state sales tax. The EIN never replaces state registration. See our state tax ID guide for the distinction and our EIN cost breakdown for the federal side.
How to Apply
How Do You Get an EIN in Kansas?
You get an EIN in Kansas through 1 of 4 IRS methods: online, fax, phone, or mail. The method depends on whether you have a US Social Security Number. The process is federal and identical in every state, so a Kansas applicant follows the same steps as a Texas or Florida applicant.
| Method | Speed | Cost | SSN Required |
|---|---|---|---|
| Online | Instant | $0 | Yes |
| Fax | 4-7 days | $0 (DIY) / $49 (ein.so) | No |
| Phone | Same day (some) | $0 | Varies |
| 4-6 weeks | $0 | No |
A US resident with an SSN uses the IRS online tool at irs.gov and receives the EIN instantly at no cost. A non-resident without an SSN cannot use the online tool. The non-resident path is the fax method, where the passport number replaces the SSN. See the full how to get an EIN walkthrough and the EIN processing time details.
Steps for a Kansas Business

Submit and Receive Your EIN
Non-Residents
Can a Non-US Resident Get an EIN for a Kansas LLC?
Yes. A non-US resident can get an EIN for a Kansas LLC without an SSN or an ITIN. You enter your passport number on Form SS-4 Line 7b and fax the form to the IRS at 855-215-1627. The IRS issues the EIN to non-residents the same way it does to residents.
The blocker is the IRS online tool. It requires a US SSN, so it locks out every foreign founder. That is not a dead end. The fax method exists precisely for applicants without an SSN. The cost of the EIN is still $0 from the IRS; the work is in preparing Form SS-4 correctly and reaching the IRS fax line.
No SSN or ITIN Needed
Fax Is the Path
Address Formatting Matters
ein.so Files It for You
Many non-residents pick Kansas, Wyoming, New Mexico, or Delaware for their LLC and attach the EIN to that entity. The EIN process does not change with the state. See the SS-4 form guide for field-by-field instructions.
Cost
How Much Does an EIN in Kansas Cost?
The IRS charges $0 for an EIN in Kansas. The number itself is always free. The cost depends on how you file and whether you have an SSN. A US resident pays nothing by applying online. A non-resident pays a service to prepare and fax Form SS-4 correctly.
| Scenario | EIN Cost | Time | Notes |
|---|---|---|---|
| US resident, online | $0 | Instant | SSN required |
| Non-resident, DIY fax | $0 | 4-7 days | Must reach IRS fax, format SS-4 |
| ein.so Standard | $49 | 4-7 days | Passport, no SSN needed |
| ein.so Express | $97 | 2-3 days | Faster IRS handling |
The $49 and $97 fees pay for accurate SS-4 preparation, correct address formatting, and direct fax filing to 855-215-1627. They do not represent an IRS charge. A separate Kansas Secretary of State filing fee applies when you form the LLC. Confirm that fee on the official state site, because it changes. See our EIN cost guide for the full federal breakdown and EIN processing time for delivery windows.
