Formation documents for a business are the legal papers you file with your state to create an entity like an LLC, corporation, or limited partnership. The specific document depends on the structure you’re forming: an LLC files articles of organization, a corporation files articles of incorporation, and a limited partnership files a certificate of limited partnership. You submit these to the Secretary of State (or equivalent agency) in the state where you want your business to exist, and the state’s acceptance is what turns your business from a person doing work into a legally recognized entity.1U.S. Small Business Administration.

Which Document You File for Each Business Structure
Every structure has its own formation document, and the names shift slightly from state to state even when the content is the same.
- LLC. File articles of organization. Some states use the label “certificate of organization” or “certificate of formation” for the identical document.1U.S. Small Business Administration. Register Your Business
- Corporation. File articles of incorporation, sometimes called a certificate of incorporation. This filing creates the corporation as a legal entity separate from its shareholders.1U.S. Small Business Administration. Register Your Business
- Limited partnership (LP). File a certificate of limited partnership. The partnership legally begins when the state accepts the filing.1U.S. Small Business Administration. Register Your Business
- Limited liability partnership (LLP). File a certificate of limited liability partnership, or an LLP registration, depending on state terminology.
- Sole proprietorship. No formation document. You’re automatically a sole proprietor if you conduct business without registering as another entity. You may still need to register a “doing business as” (DBA) name if you operate under anything other than your own legal name, plus any local business licenses.2U.S. Small Business Administration.

What Information the Document Requires
Requirements vary by state and entity type, but the same core details appear on nearly every formation document. Have these ready before you start the filing:
- Business name. The name must be distinguishable from other entities already registered in your state. Most states also require a designator that signals the entity type, such as “LLC,” “Inc.,” or “Corp.”3U.S. Small Business Administration. Choose Your Business Name
- Registered agent. Every LLC, corporation, and partnership needs a registered agent in the state of filing. This is the person or company designated to receive legal papers and official government correspondence on your business’s behalf. A P.O. box will not work; the agent needs a physical street address.1U.S. Small Business Administration. Register Your Business
- Principal office address. The main address where the business operates or keeps its records.
- Business purpose. Most filers use a general statement covering any lawful business activity. A few states want something more specific, but a broad purpose lets you shift direction later without amending.
- Management structure. For LLCs, some states require you to say whether the company is member-managed or manager-managed. For corporations, expect to list the number of authorized shares and, in some states, the names of initial directors.
How to File
You submit the completed document to the Secretary of State’s office in the state where you’re forming the entity. Most states accept online filings, which usually process faster than paper submissions mailed or delivered in person. Filing fees vary, but the SBA notes that total registration costs are typically less than $300.1U.S. Small Business Administration. Register Your Business
The state reviews your filing for completeness and compliance with naming rules. Once approved, you receive a stamped or certified copy confirming your entity’s legal existence. A handful of states add extra steps at formation. Arizona, Georgia, Nebraska, New York, and Pennsylvania, for example, require newly formed LLCs to publish a notice of formation in a local newspaper within a set timeframe.
Sequence matters if you’ll need an Employer Identification Number. Form your entity with the state first, then apply to the IRS for the EIN. The IRS instructs businesses to complete state formation before applying, and applying out of order can delay the process.4Internal Revenue Service. Get an Employer Identification Number
Formation Documents Are Not Governance Documents
People often mix up formation documents with the internal rules that govern how a business operates. They are different things, and you generally need both. Formation documents are public records filed with the state that create the entity. Governance documents are private, internal agreements that set out how the business runs day to day. Governance documents are not filed with the state.
Corporate Bylaws
After filing articles of incorporation, a corporation adopts bylaws as its internal rulebook. Bylaws cover the number of directors, how meetings are called and run, voting procedures, and officer roles. The articles create the legal shell; the bylaws fill it with operational rules.
LLC Operating Agreements
An operating agreement does for an LLC what bylaws do for a corporation. It spells out ownership percentages, how profits and losses are divided, each member’s responsibilities, and procedures for admitting or removing members. Only a handful of states legally require one, but the SBA strongly recommends creating an operating agreement regardless. Without one, your state’s default LLC rules govern your business, and those defaults rarely match what the members actually intended.5U.S. Small Business Administration. Basic Information About Operating Agreements
Partnership Agreements
LPs and LLPs should have a written partnership agreement defining each partner’s duties, decision-making authority, and financial arrangements. The certificate filed with the state establishes the partnership’s existence; the internal agreement governs how the partners actually work together.1U.S. Small Business Administration.

After Filing: Ongoing Obligations
Filing is not a one-time task. Most states require LLCs and corporations to file periodic reports, usually annually or every two years, to keep their registration current. These reports update the state on your current business address, registered agent, and the names of directors, officers, or members. The requirement typically starts the year after formation and continues until the entity is formally dissolved.
Missing these reports has real consequences. States can administratively dissolve your entity or revoke its good standing, which strips away liability protection and can prevent the business from enforcing contracts or filing lawsuits under its own name. Reinstating a lapsed entity usually costs more than staying current, and some states charge back fees and penalties for the missed years.
You’ll also need to file amendments when certain details change: the business name, an LLC’s management structure, the number of authorized shares, or the stated business purpose. The process is to authorize the change internally (a board vote or member consent, following whatever your bylaws or operating agreement require) and then file the amendment paperwork with the Secretary of State. Expect a filing fee for each amendment.
Why Filing Correctly Matters
The main legal benefit of properly filed formation documents is the liability shield between you and your business. For LLCs and corporations, business debts and legal claims belong to the entity, not to you personally. Your personal bank accounts, home, and other assets are generally off-limits to business creditors.6Legal Information Institute. Limited Liability Without formation documents on file, you’re just a person doing business, and creditors can reach everything you own.
That protection depends on treating the entity as genuinely separate. Courts can “pierce the corporate veil” and hold owners personally liable when the business is run as an alter ego of the owner: personal expenses paid from the business account, no meetings held or minutes kept, annual reports never filed, no registered agent maintained. No single failure is usually decisive, but the pattern is what matters. Formation documents create the legal structure; you have to respect that structure for it to protect you.
Beyond liability, formation documents are how the outside world verifies your business is real. Banks require them to open a business account. The IRS requires them before issuing an EIN.7Internal Revenue Service. Employer Identification Number Licensing agencies, landlords, vendors, and investors all check these public records to confirm the business exists and is in good standing. Without a current certificate of formation or good-standing letter, ordinary business steps get harder.
