LLC Legal Documents: Everything You Need For Your Business

This post was originally published on October 31, 2019, and has been updated for accuracy, comprehensiveness, and freshness on March 16, 2026.

To no one’s surprise, there’s paperwork involved with opening up a new LLC. Some of these forms are required by law, while others are simply recommended to keep you protected going forward. 

If you're wondering which LLC legal documents you need, this guide breaks it down and explains why each one is important.

What are LLC legal documents?

LLC documents are the official paperwork that establish your business and outline how it operates. They have two purposes:

1. They prove your business exists in the eyes of the state
2. They set the rules for how your business operates

Required vs. good to have documents 

Not all LLC documents carry the same weight. Some are legally required, meaning if you skip them, the state won't recognize your business. Others aren't required but are helpful to have because they protect you if something goes wrong.

For example, the law requires you to have Articles of Organization. But an operating agreement, while not required by every state, can save you from messy disputes between members down the road.

Key LLC legal documents

These are the primary business formation documents you should have when starting an LLC. Some are filed with the state, while others stay with you. 

Articles of organization

Your Articles of Organization (also called a Certificate of Organization in some states) is the document that officially creates your LLC. Without it, your business doesn't exist in the eyes of the state. This is the most important of all entity documents for LLC formation.

Think of it like a driver's license for your business. It tells the state the basics about who you are and what you do. Most states require you to include:

• Your LLC's name
• The purpose of your business
• Your principal and mailing address
• How long your LLC will operate
• Your registered agent's name and address
• Whether the LLC is member-managed or manager-managed

Some states also ask you to list your members, their initial contributions, and a liability clause. Once your articles are filed and approved, keep a copy with your registered agent.

Employee Identification Number (EIN)

An Employer Identification Number (EIN) is similar to a Social Security number for your business. The Internal Revenue Service (IRS) uses it to identify your LLC for tax purposes. You will need an EIN if you plan to:

• Hire employees
• Open a business bank account
• File separate business tax returns 

Getting an EIN is free through the IRS website. Even if you are a single-member LLC, getting an EIN keeps your personal Social Security Number off of your business documents (a smart move for safety and privacy).

Operating agreement

An operating agreement is an internal document that lays out how your business runs. It covers ownership percentages, voting rights, profit sharing, and what happens if a member wants to leave.

Most states don't require you to file one, and some don't even require it to be in writing. But we still recommend putting one together. 

A good operating agreement will cover:

• What each manager and member is responsible for
• How meetings are called and how votes work
• How profits and losses are split
• How members can buy in or sell their shares
• Tax setup, like how the LLC is classified and what accounting method it uses
• How to make changes to the agreement
• Procedures for removing members from the LLC
• How to close the business if it comes to that

Many operating agreements also include clauses that protect members from personal liability and keep the rest of the agreement valid even if one part gets thrown out. Just make sure it lines up with your Articles of Organization. If the two ever conflict, the Articles win.

Keep in mind that even if not required by your state, that businesses like banks may require you to give them a copy to open a bank account.  

Once your agreement is finalized, for more details on formalizing it, read about whether an operating agreement needs to be notarized. 

Other important LLC legal documents

Beyond just the basics, there are several other LLC documents you may need depending on your situation:

• Business licenses and permits: Depending on the industry you operate in and your location, you may need federal, state, or local licenses to operate legally.
• Tax registration forms: You'll probably need to register for state taxes, and possibly local taxes, depending on where you do business.
• Meeting minutes: Keeping track of meeting minutes can protect everyone later if disputes arise. 
• Certificates of Membership: If more than one member, member certificates support ownership percentages or units.  
• Certificate of amendment: If you need to change your LLC's name, address, or structure, you will file this with the state.
• Certificate of dissolution: If you want to close your LLC, this document officially ends your business with the state. 

All of these documents can help keep your LLC legally compliant and protected as your business grows.
