Educational guide, not legal or tax advice.
An EIN is a federal tax identification number issued by the IRS. A Delaware LLC may need one for banking, payroll, multi-member ownership, federal tax filings, Delaware business licensing, or tax registration.
The EIN is free when you apply directly with the IRS. It is not included in the Delaware Certificate of Formation.

When a Delaware LLC needs an EIN
Common reasons:
- More than one member
- Employees
- Bank account
- Corporate tax election
- Partnership tax filing
- Vendor or platform onboarding
- Delaware license or tax setup
- Foreign state registration or tax accounts
A single-member LLC with no employees may not always need an EIN for federal tax purposes, but many banks and platforms ask for one.
Common EIN mistakes
Applying before the LLC exists
If the Delaware name changes or filing fails, IRS records can become inconsistent.
Paying a third-party website for a free EIN
The IRS does not charge for direct EIN applications.
Confusing EIN with annual tax
Getting EIN does not pay Delaware’s $300 annual tax.
Losing the confirmation letter
Save the EIN letter immediately. Banks often request it.
EIN FAQ
Does every Delaware LLC need an EIN?
Not always for federal tax purposes, but many do for banking, multi-member ownership, employees, or license/tax setup.
Is EIN included in Delaware LLC formation?
No. Some formation services add it as a service, but the official IRS EIN application is separate and free.
Should I get EIN before the operating agreement?
For a simple single-member LLC, either can be prepared after formation. For multi-member LLCs, align the EIN application with the agreement’s ownership and tax facts.
Does a Delaware LLC owe tax if it has EIN?
EIN itself does not create Delaware tax, but the LLC still owes Delaware annual tax and may have federal, Delaware, or other-state tax filings depending on facts.
