Getting an EIN for Your Tennessee LLP

The IRS assigns each business a nine-digit federal tax identifier called an Employer Identification Number. Think of it as a Social Security number for the business: it identifies the firm on tax filings, bank accounts, and payroll. For some business types, an EIN is optional. For a partnership, it is not.

Why the partnership form requires it

Because an LLP is taxed as a partnership by default, it must file a federal partnership return (Form 1065) each year and issue a Schedule K-1 to each partner. A partnership cannot use any individual partner's Social Security number for these filings — it needs its own EIN. So while a single-member LLC might get by without one, an LLP always needs an EIN from the start.

Where you will use it

• On the firm's federal partnership return and the K-1s issued to partners
• To open the firm's business bank account, which every bank requires
• To register for Tennessee tax accounts, such as franchise and excise or sales tax
• To hire employees and handle payroll tax reporting

Gathering a few pieces of information before you start makes the application quick. The IRS asks for details about the firm and about the person applying on its behalf.

Information to have ready

• The firm's legal name exactly as registered with the Tennessee Secretary of State, including the LLP designation
• The firm's mailing address and principal business location
• The responsible party's details. The IRS requires a "responsible party" — a partner who controls or manages the firm — along with that person's name and taxpayer identification number (SSN or ITIN)
• The type of entity (partnership) and the reason you are applying (starting a new business)
• The number of partners and the expected number of employees, if any
• The date the business started or will start

Register with the state first

It is best to have your LLP registered with the Secretary of State before you apply for the EIN, so the firm's legal name is settled and matches what you tell the IRS. Applying with a name you have not secured can create mismatches you will have to untangle later.

The IRS offers several ways to apply, and it issues the EIN at no cost. Be skeptical of any service that charges a fee merely to obtain an EIN on your behalf — the number itself is always free from the IRS.

Online (fastest)

The online EIN Assistant at IRS.gov is the quickest route. The application takes about ten minutes, and the IRS issues the number immediately upon completion, so you can print the confirmation letter and use the EIN the same day. The online tool is available during the IRS's posted hours and must be completed in a single session. The responsible party completing it online needs a US Social Security number or ITIN.

By fax or mail

If the responsible party does not have an SSN or ITIN, or you prefer not to apply online, you can file Form SS-4 by fax or mail. Fax applications are typically processed within a few business days; mailed applications take longer. This is the standard route for firms whose responsible party is a non-US person.

One EIN per firm

Apply for a single EIN for the LLP. You do not need separate EINs for each partner or each bank account. If the firm later changes structure significantly, consult a CPA about whether a new EIN is required, but for ordinary operation, one EIN serves the whole partnership.

Most EIN problems come from small errors that are easy to prevent once you know to look for them. A little care up front saves time reconciling records later.

Watch out for these

• Name mismatch. The name you give the IRS should match the firm's registered legal name. A discrepancy between the EIN records and the Secretary of State records can cause friction with banks and tax authorities.
• Paying for a free service. Never pay a fee solely to obtain an EIN. The IRS provides it for free. Preparing the whole formation package is a legitimate service; charging for the EIN alone is not something you should accept.
• Choosing the wrong responsible party. The responsible party should be a partner who genuinely controls or manages the firm, with accurate identifying information. Naming the wrong person creates problems if the IRS needs to reach the firm.
• Applying before you are ready. Because the online tool must be completed in one session and issues the number immediately, have all your information gathered before you start so you are not forced to abandon and restart.
• Losing the confirmation. Save the EIN confirmation letter (Form CP 575). Banks and agencies may ask for it, and it is the cleanest proof of the number.

The EIN unlocks the practical steps that turn a registered LLP into an operating business. With the number in hand, the firm can open accounts, register for taxes, and start functioning as a real entity.

What the EIN lets you do next

• Open the business bank account. Bring the EIN confirmation, the filed LLP registration, the partnership agreement, and signer IDs to open the firm's account and keep partnership finances cleanly separate.
• Register for Tennessee taxes. Use the EIN to set up any required state tax accounts through the Department of Revenue, such as franchise and excise or sales tax, depending on the firm's activities.
• Set up payroll. If the firm will have employees, the EIN is the foundation for payroll tax reporting at the federal and state levels.
• File the partnership return. At tax time, the EIN identifies the firm on Form 1065 and on each partner's K-1.

Getting the EIN is quick and free, but it sits at the center of everything the firm does financially. Handle it right — matching the registered name, naming a proper responsible party, and keeping the confirmation — and the rest of the firm's financial setup goes smoothly.
