The primary LLC formation documents include the Articles of Organization, Operating Agreement, EIN Confirmation Letter, Registered Agent Information, and any required state compliance documents. These documents establish your LLC, verify ownership, and ensure legal compliance.
Whether you are a US resident or a non-resident, understanding these documents is essential for successfully forming and operating an LLC.
Essential LLC Formation Documents
1. Articles of Organization
The Articles of Organization is the document that officially creates your LLC.
This document is filed with the Secretary of State in the state where you form your company.
It typically includes:
- LLC name
- Business address
- Registered agent details
- Business purpose
- Management structure
Once approved, your LLC becomes a legally recognized business entity.
2. Operating Agreement
An Operating Agreement outlines how the LLC will be managed.
Although not required in every state, it is strongly recommended.
The document covers:
- Ownership percentages
- Member responsibilities
- Profit distribution
- Voting rights
- Management procedures
Having an Operating Agreement helps prevent future disputes and demonstrates business legitimacy.
3. EIN Confirmation Letter (CP 575)
An Employer Identification Number (EIN) is issued by the IRS.
After approval, the IRS provides an EIN confirmation letter.
This document is required for:
- Opening a US business bank account
- Filing taxes
- Working with payment processors
- Hiring employees
For many businesses, the EIN confirmation is one of the most important post-formation documents.
4. Registered Agent Documentation
Every LLC must have a registered agent.
The registered agent receives:
- Legal notices
- Government correspondence
- Compliance reminders
Many states require proof of registered agent appointment during the formation process.
5. Certificate of Formation or Certificate of Organization
Some states issue a Certificate of Formation after approving the LLC.
This document serves as official proof that the company exists.
Banks, payment processors, and investors may request this document during verification procedures.
Additional Documents Often Required
Business Address Documentation
Many entrepreneurs obtain a professional US business address.
Supporting documents may include:
- Address agreements
- Mail forwarding agreements
- Virtual office documentation
These documents can be useful for banking and business verification purposes.
Banking Resolution
When opening a business bank account, some financial institutions may request a banking resolution that authorizes account management.
This is especially common for multi-member LLCs.
Ownership Documentation
Certain banks and payment providers may request beneficial ownership information.
This helps verify:
- Company owners
- Ownership percentages
- Control persons
LLC Documents Required for Non-US Residents
Non-US residents generally need:
- Passport copy
- Articles of Organization
- EIN Confirmation Letter

Many international entrepreneurs use these documents to establish banking relationships and operate globally.
