Getting an EIN for Your Kansas LLP

An Employer Identification Number is a nine-digit number the IRS assigns to a business. Think of it as a Social Security number for your partnership — the identifier the federal government, banks, and other institutions use to recognize the LLP as a distinct taxpayer.

Every multi-partner LLP needs one

Unlike a single-member LLC, which can sometimes use the owner's Social Security number, a partnership always needs its own EIN. That's because a partnership files its own federal informational return — Form 1065 — and issues a Schedule K-1 to each partner showing their share of income. You can't file a partnership return on an individual's Social Security number, so the EIN is mandatory from the start. Since every LLP has at least two partners by definition, every Kansas LLP needs an EIN.

What you use it for

• Federal tax filing — the partnership return and the K-1s issued to partners
• Opening a business bank account — banks require the EIN to open an account in the partnership's name
• Hiring employees and running payroll — payroll tax reporting is tied to the EIN
• Vendor and client paperwork — the number others use to report payments to your partnership

The EIN is free. The IRS issues it at no charge, and the fastest way to get one is the online application on the IRS website. Be wary of any service that presents "getting an EIN" as a paid product on its own — you're only ever paying for the convenience of someone else doing the application, never for the number itself.

The online application

Apply through the IRS EIN Assistant. The application takes roughly ten minutes, and when you finish, the EIN is issued immediately. You can download and print the confirmation notice and start using the number the same day — no waiting for anything in the mail.

The responsible party

The application asks for a "responsible party" — a person who controls or manages the partnership, usually one of the partners. The responsible party must be a real individual with their own taxpayer ID, not another entity. The IRS uses this to keep a real person accountable for the EIN.

Applicants without a U.S. taxpayer ID

The online application requires the responsible party to have a U.S. Social Security number or ITIN. A partnership whose responsible party doesn't have one can still get an EIN — it just applies by fax or mail using Form SS-4 instead of the online tool, which takes longer but reaches the same result.

The order in which you register the LLP and obtain the EIN matters a little, and getting it right avoids a small snag.

Register the LLP first

It's generally best to file your Statement of Qualification with the Kansas Secretary of State and have the LLP officially registered before applying for the EIN. That way the partnership name you put on the EIN application exactly matches the registered entity, and there's no mismatch between your federal and state records. Because Kansas processes online filings quickly, this rarely causes any real delay.

Then apply, then bank

With the LLP registered and the EIN in hand, you have the two documents banks want to open a partnership account: the filed Statement of Qualification and the EIN confirmation. Getting the EIN before you head to the bank keeps the account-opening appointment from stalling.

A few recurring issues trip up new partnerships. Knowing them in advance saves time.

Applying too early or with the wrong name

If you apply for the EIN before the LLP is registered, or under a name that doesn't match your Statement of Qualification, you can end up with a federal record that doesn't line up with your state record. It's cleaner to register first and apply under the exact registered name.

Losing the confirmation

The EIN confirmation notice (the IRS calls it the CP 575) is issued once. Save it somewhere permanent — you'll need the number and often the notice itself for banking and filings. If you lose it, the IRS can provide a confirmation letter, but that's an extra step you can avoid by filing it away when you get it.

Thinking the EIN replaces state registration

The EIN is federal; it doesn't register your partnership with Kansas. You still need the Statement of Qualification with the Secretary of State to be a registered LLP. The two are separate systems — federal tax ID on one side, state entity registration on the other — and you need both.

Paying for something free

Because the EIN is free from the IRS, there's no reason to pay a standalone fee for the number. If a service bundles EIN acquisition with genuine convenience — doing it for you as part of a broader package — that can be worth it for your time, but you should always know you're paying for the service, not for a number that the IRS gives away.

Getting the EIN is one link in the chain of standing up a Kansas LLP: register with the Secretary of State, get the EIN from the IRS, put a partnership agreement in place, and open a business bank account. Each step supports the others.

When you register through Mainstay Filing, we handle the state-facing Statement of Qualification and can point you to the IRS application so your EIN lines up with the registered entity. The EIN application itself is quick enough that many partners simply do it themselves right after registration — it's genuinely a ten-minute task on the IRS site. What matters is that you get it directly from the IRS, apply under your exact registered name, and keep the confirmation somewhere safe for the life of the partnership.
