Getting an EIN for Your Kansas Limited Partnership

The Employer Identification Number is a nine-digit federal tax ID issued by the IRS — essentially a Social Security number for a business. For a limited partnership, it is not optional. A partnership has more than one owner by definition, which means it cannot use any individual's Social Security number for its own tax and banking; it needs its own EIN.

The reasons an LP must have one

• It files a partnership tax return. An LP files an informational federal return (Form 1065) and issues K-1s to the partners. That return requires the partnership's own EIN.
• Banks require it. No reputable bank will open a business account for a limited partnership without an EIN. Since keeping partnership money separate from personal money is essential, the EIN is a prerequisite to banking.
• Hiring and payroll. If the LP will have employees, the EIN is used for payroll tax reporting.

Get it after the certificate is accepted

The cleanest sequence is to form the LP first — file the Certificate of Limited Partnership and get it accepted by the Kansas Secretary of State — then apply for the EIN. Applying for the EIN of an entity that does not yet legally exist creates mismatches you would rather avoid. Once the partnership is on record, the EIN application goes smoothly.

The IRS application is quick, but it goes fastest when you have your information assembled beforehand. Gather these before you start so you are not hunting for details mid-application.

Have this ready

• The exact legal name of the partnership as filed on your Kansas Certificate of Limited Partnership — it should match the state record precisely.
• The partnership's address, which can be the principal business address.
• The responsible party's details. The IRS requires a "responsible party" — a person who controls or manages the entity, typically a general partner — along with that person's name and Social Security number or ITIN.
• Basic details about the partnership, such as when it started and its general nature.

Who is the responsible party?

For an LP, the responsible party is generally a general partner, since general partners manage the business. The IRS wants a real individual behind the entity, not just another company, as the responsible party for its records. Choose the general partner who will be the point person for the partnership's tax matters.

The most common and fastest route is the IRS online EIN Assistant, which issues the number immediately at no cost. Applying directly through the IRS is always free — the EIN itself never carries a fee.

The online application

1. Go to the EIN Assistant on IRS.gov and select that you are applying for a partnership.
2. Enter the partnership's legal name and address exactly as they appear on the Kansas certificate.
3. Provide the responsible party's name and SSN or ITIN.
4. Answer the basic questions about the partnership.
5. Submit, and the IRS issues the EIN on the spot. Save and print the confirmation immediately — you will need it for banking.

The whole thing usually takes about ten minutes. The online tool is available during IRS operating hours and must be completed in a single session; it does not save partway through.

If you can't apply online

A responsible party without a US Social Security number or ITIN cannot use the online tool. In that case you apply by fax or mail using Form SS-4, which takes longer — days by fax, weeks by mail — but reaches the same result. International applicants can also apply by phone in some circumstances.

Getting an EIN is simple, but a few avoidable errors cause real headaches — usually at the bank, when a mismatch stops you from opening an account.

The pitfalls

• Name mismatch. If the name on the EIN does not exactly match the Kansas certificate, banks and the IRS can flag it. Enter the legal name precisely as filed.
• Applying before the LP exists. Get the certificate accepted first. An EIN tied to an entity Kansas has not yet recognized invites confusion.
• Paying a third party for the number itself. The EIN is free from the IRS. Some services charge a fee just to obtain it; you can get it directly at no cost.
• Losing the confirmation. The IRS issues the confirmation once. Save the PDF and store it somewhere you will find it — you will be asked for it when opening the bank account and at tax time.
• Choosing the wrong responsible party. Use a general partner who genuinely manages the entity, and keep the IRS updated if that person changes.

After you have it

With the EIN in hand and the confirmation saved, you can open the partnership's bank account, set up any payroll, and file the partnership return when due. The EIN stays with the LP for its life; you generally do not need a new one unless the entity's structure fundamentally changes.

Keep the EIN record current

If the partnership's responsible party changes — say the general partner who handles tax matters steps aside and another takes over — the IRS expects you to update its records. There is a specific form for reporting a change in responsible party, and keeping that current avoids the IRS sending important notices to someone no longer involved. It is a small housekeeping item that prevents mail from going astray at tax time.

One EIN per entity

A limited partnership gets exactly one EIN, and it uses that number for the life of the entity. You do not get a separate EIN for each partner, each bank account, or each state you operate in. If you later qualify the LP to do business in another state, or open additional accounts, you use the same EIN throughout. The number is tied to the partnership itself, not to any particular activity or location.
