Getting an EIN for Your Utah Limited Partnership

An Employer Identification Number is a nine-digit federal tax ID assigned by the IRS. Think of it as the business equivalent of a Social Security number: it identifies your limited partnership on federal tax filings, at the bank, and to anyone who needs to report payments to the entity. The IRS issues it at no cost.

Why an LP always needs one

Unlike a single-member LLC, which can sometimes get by on the owner's Social Security number, a limited partnership needs its own EIN from the start. The reason is structural: an LP has at least two partners, so it files an informational partnership return (Form 1065) and issues a Schedule K-1 to each partner. A partnership return can't be filed on an individual's SSN — it needs the entity's own federal ID.

Where you'll actually use it

• Filing the LP's Form 1065 and issuing K-1s to the partners each year
• Opening the LP's business bank account — banks won't open a partnership account without it
• Hiring employees and running payroll, if the LP has staff
• Setting up merchant processing, vendor accounts, and licenses that ask for a federal tax ID

Get the EIN early. It's one of the first things you'll be asked for after the Certificate of Limited Partnership is accepted, and nothing about banking or payroll moves without it.

File the certificate first

The cleanest sequence is to form the LP first, then get the EIN. You'll want your LP's exact legal name and formation details when you apply, and applying against an accepted Certificate of Limited Partnership avoids mismatches between what the IRS has on file and what Utah has. Because Utah typically processes online formations the same day, this isn't much of a wait.

The online application

Apply through the IRS EIN Assistant at IRS.gov. It's the fastest route: the application takes about ten minutes, and the IRS issues the number immediately at the end, so you can print the confirmation and use it the same day. A few practical notes:

• The tool is available during set hours, not around the clock, so plan accordingly
• You complete it in one sitting — it doesn't save partway through
• You'll designate a responsible party, which for an LP is generally a general partner who controls or manages the entity
• The responsible party needs a valid U.S. Social Security number or ITIN to complete the online version

If you can't use the online tool

A responsible party without an SSN or ITIN — common for LPs with foreign general partners — applies using Form SS-4, submitted by fax or mail. It's slower than the instant online issuance, so build in extra time if this is your situation. The form asks the same core questions; it just takes a different path to the IRS.

Having your information ready before you start makes the online application quick. Here's what you'll need for a Utah LP.

The details to gather

• The LP's exact legal name as filed on the Certificate of Limited Partnership, plus any trade name (DBA) if you have one
• The Utah address for the LP
• The responsible party's name and SSN or ITIN — generally a general partner
• The entity type — you'll indicate the LP is a partnership for tax purposes
• The number of partners and the reason you're applying (new business, banking, hiring, etc.)
• The date the LP started or will start business

A note on the responsible party

The IRS wants a real person as the responsible party — someone who ultimately owns or controls the entity — not another entity, in most cases. For a typical LP that's a general partner. If your LP uses an entity as its general partner, the responsible party is generally the individual who controls that upper entity. If the responsible party ever changes, the IRS expects you to update it using Form 8822-B.

An EIN application is short, but a handful of errors cause real delays or headaches down the line.

The mistakes we see

• Applying before the LP is formed. If you get an EIN and then the LP's name comes out differently on the certificate, you've got a mismatch to untangle. Form first, then apply.
• Using a paid "EIN service" that charges for a free thing. The IRS issues EINs for free. There's no need to pay a third party a fee for the number itself.
• Naming the wrong responsible party. For an LP it should be a general partner (or the individual controlling an entity general partner), not a limited partner and not an outside advisor.
• Losing the confirmation letter. The CP 575 confirmation is the document banks and agencies ask for. Save a copy the moment you get it — replacing it later means requesting a 147C letter from the IRS, which is a hassle.
• Forgetting to update after changes. If the responsible party changes, file Form 8822-B. If you forget, IRS records drift out of date.

How Mainstay Filing helps

We form your Utah LP by preparing and filing the Certificate of Limited Partnership, which is the foundation the EIN sits on. The EIN application itself is a quick, free step with the IRS that follows formation — we make sure the entity is properly on file first so your application matches Utah's record and there's nothing to reconcile later. If you have questions about the responsible-party designation or a foreign general partner, that's worth a word with your CPA before you apply.
