EIN for a Delaware LLC in 2026

Last updated: 2026-10-07

An Employer Identification Number (EIN) is your Delaware LLC's federal tax identity — needed for a business bank account, hiring employees, and filing taxes. The EIN itself is free from the IRS. This guide covers the IRS application basics, the responsible-party and SSN/ITIN rules (including for non-residents), and the Delaware-specific tax notes that pair with an EIN. llcformation.io/ is an independent private service — not a government agency — and this is general information, not tax advice.

What an EIN is and why your Delaware LLC needs one

An EIN (Employer Identification Number, also called a Federal Tax ID) is a nine-digit number the IRS assigns to your LLC — your business's federal tax identity.

You will need an EIN to:

• Open a US business bank account — most banks require one (critical for non-resident Delaware LLC founders).
• Hire employees — no payroll or employment tax filings without it.
• File federal taxes for the LLC.
• Work with payment processors and vendors that request a tax ID.

Even a single-member Delaware LLC with no employees usually gets one, because banks ask for it. The IRS issues EINs for free — there is no legitimate IRS fee, ever.

How to apply: the EIN itself is free

The IRS offers three routes:

1. Online application — fastest for eligible applicants (the responsible party needs an SSN or ITIN). The EIN is issued at the end of the session.
2. Fax (Form SS-4) — the completed form goes to the IRS; the number is returned by fax.
3. Mail (Form SS-4) — slowest; used when the applicant has no SSN/ITIN.

Rules to remember:

• Apply only once — an LLC gets exactly one EIN.
• Apply after formation, using the LLC's legal name and Delaware as the formation state.
• Use irs.gov only. Third-party "EIN filing" sites charging a fee are not the IRS.

Responsible party, SSN/ITIN, and non-resident realities

Every application names a responsible party — the individual who ultimately owns or controls the LLC:

• The responsible party must be an individual, not a company.
• The online application requires the responsible party to have a valid SSN or ITIN.
• Applicants without an SSN or ITIN — including non-resident founders — apply by fax or mail with Form SS-4 instead.

For non-US residents: Delaware is the most common formation state for non-resident founders, and the EIN is usually the critical piece of the puzzle (banks require it). The SS-4-by-fax route is the standard path, and authorized designees can act on the application. Expect this to take meaningfully longer than an online issuance — start early and plan your bank-account timeline around it. You do not need an ITIN first just to get the EIN; the SS-4 route exists for exactly this case.

The EIN application names the responsible party to the IRS privately; it is not a Delaware public filing.

Delaware tax notes: what the EIN does not cover

Your EIN is federal — Delaware's own obligations are separate:

• $400 annual tax. Every Delaware LLC pays the $400 annual tax to the Division of Corporations, due June 1 (raised from $300 effective January 1, 2026 under HB 400). The EIN does not satisfy or replace this.
• No Delaware income tax for out-of-state LLCs. An LLC that does not do business in Delaware generally owes no Delaware income tax beyond the $400 annual tax.
• Division of Revenue. If your LLC does business in Delaware (employees, physical presence), it may need Division of Revenue registrations — the EIN does not register you there automatically.
• Operating elsewhere. Most Delaware LLCs operate in another state, which usually means foreign qualification and that state's tax registrations — the EIN is the federal identifier you use on all of them.

The EIN does not register you with any Delaware agency automatically. When we assist with your formation, we flag which registrations fit your business so nothing is missed.

EIN timeline and next steps

General timeline guidance (the IRS does not commit to exact dates):

• Online (SSN/ITIN holder): fastest — typically issued in the same session.
• Fax (Form SS-4): manual IRS review; allow weeks.
• Mail (Form SS-4): slowest.

Sensible order for a Delaware LLC: file the Certificate of Formation ($110) → apply for the EIN → open the bank account → arrange the $400 annual tax for the following June.
