Getting an EIN for Your Florida Limited Partnership

The IRS assigns each business an Employer Identification Number, a nine-digit federal tax ID. Think of it as a Social Security number for a business: it identifies your limited partnership to the IRS, to banks, and to anyone who needs to report payments to the entity.

Why the requirement is automatic for an LP

A limited partnership by definition has at least one general partner and at least one limited partner — so it always has multiple owners. Multi-owner entities file a partnership tax return (Form 1065) and issue a Schedule K-1 to each partner. That return requires an EIN. Unlike a single-member LLC, which can sometimes get by on the owner's Social Security number, an LP has no solo shortcut. If you're forming an LP, you're getting an EIN. Full stop.

What you'll use it for

• Filing the partnership's federal return and issuing K-1s.
• Opening a business bank account in the partnership's name.
• Hiring employees and handling payroll tax reporting.
• Registering for Florida sales tax, if the partnership sells taxable goods or services.
• Any situation where a vendor, client, or bank needs the partnership's tax identification.

The EIN application is short, but it goes faster if you have a few things settled first. Crucially, get the EIN after your Certificate of Limited Partnership is filed and accepted, so the partnership legally exists and its name and details are final.

Information to have ready

• The partnership's exact legal name as it appears on the filed Certificate of Limited Partnership, including the LP designator.
• The Florida formation date and the state of formation.
• The principal business address.
• The responsible party's information. For an LP, the responsible party is generally a general partner — the person who controls or manages the entity. The IRS wants a real individual here, with their Social Security number or ITIN, not an entity, even if an entity serves as your general partner.
• The reason for applying (started a new business) and a general description of the partnership's activity.

Settling the responsible party matters. If your general partner is an LLC, the IRS still wants an individual behind it as the responsible party — typically the person who controls that general partner entity.

The IRS issues EINs directly and for free. Be careful of third-party sites that charge for what the IRS gives away — the EIN itself never costs anything.

The online application

For the speediest path, use the IRS EIN Assistant over at IRS.gov. The online application takes about ten minutes, and if the responsible party has a US Social Security number or ITIN, the EIN is issued immediately at the end. You can download the confirmation letter (the CP 575) and start using the number the same day. The online tool is available during posted IRS hours and must be completed in one session — it times out if you leave it idle.

If you can't apply online

A responsible party without an SSN or ITIN can't use the online tool. In that case, file Form SS-4 by fax or mail. Fax turnaround is usually a few business days; mail takes considerably longer. International applicants can also apply by phone through the dedicated IRS line for foreign applicants. Plan for the extra time if this is your situation.

Getting the number is the milestone, but a couple of steps immediately follow and matter for keeping the partnership clean.

Open the bank account

With the EIN in hand and the filed certificate available, open a dedicated business bank account in the partnership's name. Keeping partnership money separate from any partner's personal money is essential — commingling undermines the whole structure and can put the limited partners' protection and the general partner's affairs at risk. Most banks want the filed Certificate of Limited Partnership, the EIN confirmation, the partnership agreement, and identification for the signers.

Keep the confirmation safe

The CP 575 confirmation letter is issued once and not reissued in the same form. Store it with your permanent partnership records. If you lose it, the IRS can provide a substitute confirmation (147C letter) on request, but it's easier to just keep the original.

Use it consistently

Use the EIN on the partnership's tax filings, on W-9s you provide to clients, and on any account or registration in the partnership's name. Consistency keeps the IRS's records and your banking aligned, which avoids headaches at tax time.

A few points trip up first-time LP owners specifically, because the partnership structure changes the usual answers.

Do I need a new EIN if partners change?

Generally, no. Ordinary changes in the partners — a limited partner coming in or going out, or a general partner change that doesn't terminate the partnership — usually don't require a new EIN. The EIN belongs to the partnership entity, not to any individual partner. Significant structural changes, like converting the LP into a different entity type, can require a new one, which is a question for your accountant.

Can an entity general partner use its own EIN for the LP?

No. The LP needs its own EIN separate from any EIN belonging to an LLC or corporation that serves as the general partner. They are distinct entities to the IRS, each with its own number and its own filings. Don't mix them.

Our formation service focuses on getting your Certificate of Limited Partnership filed correctly so the entity exists and your EIN application has an accurate foundation. The EIN itself is free and quick to obtain directly from the IRS — we point you to the right place rather than charging you for a free federal service.
