Getting an EIN for Your North Carolina Limited Partnership

An Employer Identification Number is a nine-digit federal tax ID the IRS issues to a business, at no cost. Think of it as a Social Security number for the partnership: it identifies the LP on tax filings, bank accounts, and payroll. A limited partnership isn't optional here the way a single-member LLC might be — because an LP has at least two partners, the IRS treats it as a partnership that must file its own return, and that requires an EIN.

Why an LP always needs one

• Partnership tax return: an LP files an annual information return, Form 1065, and issues a Schedule K-1 to each partner. You can't file that return without an EIN.
• Bank account: banks require the partnership's EIN to open an account in the LP's name.
• Employees and payroll: if the LP hires, the EIN is what identifies it for employment tax purposes.
• Vendor and contract paperwork: counterparties often ask for the EIN on W-9s and similar forms rather than any partner's personal number.

Using a partner's Social Security number in place of the partnership's EIN isn't an option for an LP. The partnership is a distinct filer, and it needs its own number.

When you apply, the IRS asks what kind of entity you are, and for an LP the answer is "partnership." That classification drives how the LP is taxed by default.

Partnership taxation in brief

By default, a limited partnership is a pass-through entity. The partnership itself doesn't pay federal income tax; instead, income, deductions, and credits flow through to the partners, who report their allocated shares on their personal returns. The Form 1065 the partnership files is an information return — it tells the IRS how the income was earned and how it was split, and the K-1s tell each partner what to report.

The general-partner and limited-partner distinction on taxes

The EIN application doesn't ask you to distinguish general from limited partners — that's an internal matter governed by your partnership agreement. But the distinction matters downstream: a general partner's share of partnership income is often subject to self-employment tax, while a limited partner's share frequently is not, because limited partners are passive. This is a conversation for your CPA, and it's one reason getting partnership tax advice early pays off. The EIN is just the identifier that makes all of it possible.

The application is quick, but it goes smoothly only if you have a few things settled first. Applying before your LP legally exists, or before you've named a responsible party, causes avoidable problems.

Have these ready

• Your accepted Certificate of Limited Partnership — the LP should legally exist before you get its EIN, so the number attaches to a real entity. Form the LP first, then apply.
• The partnership's legal name and address, exactly as filed
• A responsible party: the IRS requires you to name a responsible party — a person who controls or manages the partnership, typically a general partner — along with their Social Security number or ITIN
• The reason you're applying (starting a new business) and the number of partners

The responsible party must be an individual, not another entity, and the IRS uses their taxpayer ID to verify the online application. For most LPs, this is the general partner running the show.

There are three ways to apply, and the right one depends mainly on whether your responsible party has a U.S. taxpayer ID.

Online — the fastest route

Apply through the IRS EIN Assistant at IRS.gov. The application is free, takes roughly ten minutes, and issues the EIN immediately on completion — you can download the confirmation and use the number the same day to open a bank account. The online path requires the responsible party to have a valid U.S. Social Security number or ITIN. Select "partnership" as the entity type and answer the prompts about your LP.

By fax or mail — for those without an SSN or ITIN

If your responsible party doesn't have a U.S. SSN or ITIN, you can't use the online tool. Instead, complete IRS Form SS-4 and submit it by fax or mail. Fax responses typically come back within a few business days; mail takes considerably longer. Fill out the SS-4 carefully, since errors slow the process.

A word on cost

The EIN is always free directly from the IRS. Be wary of third-party sites that charge a fee for "obtaining" an EIN — they're charging for something the IRS provides at no cost. If you use a formation service, an EIN may be bundled as a convenience, but the underlying number itself has no government fee.

Once the EIN is issued, it's the partnership's permanent federal identifier. A few things follow naturally.

Put it to work

• Open the partnership's bank account using the EIN and your accepted Certificate of Limited Partnership. Keeping partnership funds separate from any partner's personal money is essential to preserving the LP's liability structure.
• Give it to your CPA so they can set up the partnership's tax filings and prepare the K-1s each partner will receive.
• Use it on partnership paperwork — W-9s, vendor forms, payroll setup — instead of any partner's personal number.
• Store the confirmation (the IRS notice) with your partnership records; you'll be asked for the EIN repeatedly over the LP's life.

If the LP's structure changes significantly down the road — a conversion to a different entity type, for instance — check with your CPA about whether a new EIN is required. For a straightforward LP that stays an LP, the original EIN carries through the life of the partnership. Our start guide shows where the EIN fits in the overall formation sequence.
