Getting an EIN for Your Alaska Limited Partnership

An Employer Identification Number is a nine-digit federal tax ID the IRS assigns to a business. Think of it as a Social Security number for the entity: it identifies the partnership on tax filings, bank paperwork, and payroll records. For an Alaska limited partnership, an EIN is mandatory — not a nice-to-have.

Why the LP structure forces the issue

A limited partnership is a pass-through entity that files its own return. Every LP must file a federal partnership return (Form 1065) and issue a Schedule K-1 to each partner reporting their share of income. Filing that return requires an EIN. Unlike a single-member LLC, which can sometimes operate on the owner's Social Security number, a partnership by its nature has multiple owners and a separate filing obligation, so it needs its own federal number from day one.

What you will use the EIN for

• Filing the partnership's annual Form 1065 and issuing K-1s
• Opening a business bank account (banks require it for a partnership)
• Hiring employees and handling payroll tax
• Establishing the partnership's identity with vendors and financial institutions

The right sequence is to form the entity first, then get the EIN. File your Certificate of Limited Partnership with the Alaska Division of Corporations and, once it is accepted, apply for the EIN. Applying after formation means the IRS record matches your legal entity name exactly, which avoids mismatches when you later open a bank account or file returns.

You do not have to wait long. Because Alaska usually processes online filings the same day the state accepts them, you can often form the LP and get the EIN within the same short window. If you apply online with the IRS, the number is issued immediately, so there is rarely a reason for the EIN to become a bottleneck.

Do not rush it before the entity exists

Getting an EIN for a partnership that has not been formally created leads to a mismatch between the IRS record and the state record. Form the LP, confirm it is on the Alaska record, then apply for the EIN with the exact legal name.

The IRS issues EINs directly and for free. Be wary of any site that charges a fee to "get your EIN" — you are paying only for someone to fill out a short, free form on your behalf.

The online method (fastest)

1. Go to the EIN Assistant on IRS.gov during its operating hours.
2. Select partnership as the entity type — this matches how an LP is treated federally.
3. Provide the responsible party's information. For a limited partnership, the responsible party is generally a general partner who controls the entity.
4. Enter the partnership's legal name (exactly as filed with Alaska), address, and formation details.
5. Submit. The EIN is issued immediately, and you can download and save the confirmation right away.

The online application takes about ten minutes and requires the responsible party to have a US Social Security number or ITIN.

If you cannot apply online

Non-US responsible parties without an SSN or ITIN, and anyone who cannot use the online tool, apply using Form SS-4 by fax or mail. Fax turnaround is typically a few business days; mail takes longer. The form asks for the same information the online tool collects.

The IRS requires every EIN application to name a responsible party — the individual who ultimately controls or manages the entity. For an Alaska LP, that is normally a general partner, since general partners run the business. The responsible party must be a real person, not another entity, and their information must be accurate because the IRS uses it as the human point of accountability for the partnership.

Mistakes that cause headaches

• Applying before the entity is formed, creating a name mismatch between the IRS and the state record.
• Entering the legal name incorrectly. It must match the Certificate of Limited Partnership exactly, or banks and the IRS may reject the pairing.
• Naming the wrong responsible party. Use a general partner who genuinely controls the LP, not a limited partner or an outside advisor.
• Paying a third party for the number itself. The EIN is always free from the IRS; a legitimate service fee is only for handling the paperwork, never for the number.
• Applying for multiple EINs. One partnership needs one EIN. If you get a duplicate by mistake, contact the IRS to sort it out rather than using both.

Once the EIN is issued, save the IRS confirmation notice somewhere permanent — you will be asked for it repeatedly. Then put it to work:

• Open the business bank account. Bring the EIN confirmation, the filed Certificate of Limited Partnership, and the partnership agreement. Keeping partnership money strictly separate from any partner's personal funds is basic hygiene and protects the entity's integrity.
• Set up payroll if the LP will have employees, registering for the appropriate federal and Alaska employment tax accounts.
• Use it on every partnership tax filing, starting with the first Form 1065 and the K-1s to partners.

The EIN stays with the partnership for its life and is never reused, even after the LP dissolves. When you eventually close the partnership, you can notify the IRS to close the business account associated with the EIN, but the number itself is simply retired. Because the EIN is a federal item, it is the same regardless of where you formed the LP — Alaska formation does not change how or where you apply.
