Getting an EIN for Your Texas LLP

An Employer Identification Number, or EIN, is a nine-digit federal tax identification number the IRS assigns to a business. It functions like a Social Security number for your partnership — it identifies the firm on tax filings, bank paperwork, and payroll accounts.

Why a partnership always needs an EIN

Unlike a single-owner business that can sometimes get by on the owner's Social Security number, a partnership can't. A limited liability partnership files its own federal information return and issues Schedule K-1s to the partners, and that requires an EIN. There's no scenario where a multi-owner LLP runs on one person's SSN.

What you'll use it for

• Filing the partnership return (Form 1065) and issuing K-1s to the partners.
• Opening the partnership's bank account — banks require an EIN for a partnership.
• Hiring employees and setting up payroll and employment tax accounts.
• Registering for state tax accounts where needed, such as sales tax with the Texas Comptroller.
• Applying for business credit, licenses, and permits.

The EIN is foundational. You'll want it in hand before you open the bank account or take on employees, which usually means getting it right after your LLP registration is on file.

The IRS issues EINs at no cost. Anyone charging you a fee for "getting an EIN" is charging for the convenience of doing the paperwork, not for the number itself. You can get it yourself in about ten minutes.

The online application

Your quickest option is the IRS EIN Assistant, available at IRS.gov. The online application:

• Is available during the IRS's posted hours.
• Takes roughly ten minutes to complete in one session.
• Issues your EIN immediately upon completion, so you can print the confirmation and use the number the same day.

To use the online tool, the responsible party — a partner who controls or manages the LLP — must have a valid US Social Security number or ITIN. You complete the application in a single sitting; the system doesn't save partial progress.

If you can't apply online

If the responsible party doesn't have an SSN or ITIN, you apply by fax or mail using Form SS-4. Fax applications generally come back within a few business days; mail takes longer. International applicants can also apply by phone in some cases. These routes take longer than the instant online issuance but reach the same result.

Who the "responsible party" is

The IRS wants a single responsible party on the application — a person who ultimately owns or controls the LLP, or who exercises effective control over it. For a partnership, that's typically one of the partners rather than the entity itself; the IRS specifically wants a natural person here, not another company, in most cases. The responsible party doesn't have to be the partner with the largest stake — it should be someone with genuine control who can stand behind the application. Choose deliberately, because the responsible party is the person the IRS associates with the EIN, and you'll want that to be someone who'll remain involved with the firm.

One application per firm

Apply once. If you're unsure whether the partnership already has an EIN — say you're formalizing a partnership that was operating informally — check your records before applying, because you don't want two EINs floating around for the same firm. If the partnership genuinely already has one from prior operations, you generally keep using it rather than requesting a new number.

The application goes quickly if you gather a few things first. Because the online tool doesn't save progress, having everything in front of you prevents a timeout that forces you to start over.

Information the IRS asks for

• The legal name of the LLP exactly as registered with the Texas Secretary of State.
• The mailing address for the partnership.
• The responsible party's name and SSN or ITIN — a partner who controls or manages the firm.
• The type of entity — you'll indicate that it's a partnership.
• The reason you're applying — typically starting a new business.
• The number of members/partners and expected employees, if any.
• The date the business started and its principal activity.

A note on timing relative to registration

It's cleanest to apply for the EIN after your LLP registration is effective with the Texas Secretary of State, so the legal name you give the IRS matches your official record. Applying before registration risks a mismatch between the name on your EIN and the name on your state filing, which can cause friction when you open a bank account.

The EIN is a building block. Once you have it, several of the next steps in setting up your LLP unlock.

Open the partnership bank account

With the filed registration, the EIN confirmation, and your partnership agreement, you can open a dedicated partnership bank account. Keeping the firm's money separate from the partners' personal funds is essential to preserving the LLP's liability shield, so do this before money starts flowing.

Set up tax and payroll accounts

Use the EIN to register for any state tax accounts you need — sales tax with the Texas Comptroller if you sell taxable goods or services — and to set up payroll if you'll have employees. The partnership files Form 1065 federally and issues K-1s to the partners, all keyed to the EIN.

Keep the confirmation safe

Save your EIN confirmation letter (the CP 575 the IRS issues) somewhere secure. You'll reference the EIN repeatedly, and replacing a lost confirmation is a hassle. Keep it with your registration documents and partnership agreement as part of the firm's core records.

One EIN per entity

Your LLP needs one EIN, and it stays with the partnership. You generally don't get a new one for routine changes. A new EIN typically comes into play only for significant structural changes — something to confirm with your CPA if your firm's structure changes materially down the road.
