Articles of incorporation are the formation document filed with the appropriate state agency to create a corporation. They identify the corporation and establish core terms of its legal structure; some states call this document a certificate of incorporation.

If you are preparing to file, start with two questions: Which state will form the entity, and what kind of entity are you forming? A general stock corporation, professional corporation, nonprofit corporation and LLC can require different documents. If you are looking for an existing company's articles, start with its formation state and exact legal name instead.

What articles of incorporation do—and what they do not do

The articles establish the corporation through the state's formation process. They also create a record that other people can consult to identify the entity and inspect its filed terms. Filing acceptance and the document's effective date matter: submitting a form or paying a fee is not, by itself, proof that formation is complete.

California's official entity-type guide explains that a corporation generally exists separately from its owners. That separation is significant, but it does not mean every owner is protected from every personal liability or that incorporating is always the best tax choice.

The filing does not complete every business setup task. It does not replace internal governance documents, licensing requirements or tax decisions. California's records guidance specifically distinguishes state formation filings from business licenses, employer identification numbers and Subchapter S tax classification. Treat formation, governance, tax registration and operating permissions as separate questions.

What usually goes in the document

Use this as a preparation map, not a substitute for your state's current form. Some items are required on a particular filing, some are optional, and others depend on the corporation type or proposed structure.

Field

Why it matters

Check before filing

Corporate name

Identifies the legal entity

Check availability, permitted endings and restrictions; use the exact spelling consistently.

Registered agent and office

Identifies who receives legal process and where

Follow the state's agent eligibility, address and consent rules; do not assume a mailing box is sufficient.

Business addresses

Supplies the required business and mailing locations

Separate the principal street address, mailing address and registered office when the form distinguishes them.

Authorized shares

Sets the stock the corporation is permitted to issue

Confirm the number and any required class, rights or par-value information; do not substitute current ownership percentages.

Purpose

States the activities the corporation may undertake

Determine whether a general clause, specific professional purpose or nonprofit language is needed.

Incorporator details and signature

Identifies and authenticates the person forming the corporation

Complete the required names, addresses and signatures; an incorporator is not automatically the owner.

Other provisions or effective date

Addresses a structure or timing choice where permitted

Check the governing requirements before adding custom clauses or postponing effectiveness.

Authorized shares are not the same as issued shares. A document permitting 1,000 shares does not establish that 1,000 have been issued, identify their owners or show how much cash the business has received. The filing and the company's actual share-issuance and ownership records answer different questions.

Optional does not mean harmless. A provision affecting share rights or governance may have consequences beyond getting a document accepted. Obtain qualified advice when the proposed structure goes beyond the standard form.

What changes by state: California and Delaware examples

Two official stock-corporation forms show why a universal template can mislead. California's ARTS-GS form, currently served with a November 2024 revision, and Delaware's stock-corporation certificate template, revised August 2026, make different requests.

Filing detail

California ARTS-GS

Delaware stock template

Document name

Articles of Incorporation of a General Stock Corporation

Certificate of Incorporation of a Stock Corporation

Addresses

Initial corporate street and mailing addresses, plus the applicable service-of-process agent details

Delaware registered office and agent, plus the incorporator's mailing address

Shares

A number of authorized shares for one class; the form says not to leave it blank or enter zero

Authorized shares and a par value in the supplied template

Purpose

A printed general-purpose statement that the form directs filers not to alter

A supplied general-purpose clause

Signature

Each incorporator signs and prints a name

The identified incorporator signs and prints or types a name

These examples apply to the named forms. They do not establish the requirements for every California or Delaware corporation. In particular, the California general stock form's purpose statement excludes specified banking, trust-company and professional activities. A founder forming a professional corporation should not use that form simply because its name looks familiar.

Delaware labels its document a template and explains that additional permitted information may require a newly drafted document. Do not infer that its simple par-value blank is the only stock structure Delaware law allows. Likewise, do not assume California's single-class form is suitable for a planned multiple-class structure.

Check current official instructions and fees at the time of filing. There is no national filing fee, and document length, stock structure, certification or expedited processing can affect what a particular filing costs.

An annotated example from a real state form

California ARTS-GS includes the sentence: “This corporation is authorized to issue only one class of shares of stock.” That is an actual sentence in the state form, not sample language invented for this article.

Read it in three parts. “Authorized to issue” concerns permitted issuance, rather than shares already sold. “Only one class” is a structural limitation built into this form. The separate number blank must then be completed; the form expressly rejects leaving it blank or entering zero.

Hypothetical: two founders intend to offer common shares to themselves and preferred shares to an investor. Their plan does not fit the form's one-class statement. The useful next step is to review the correct document and share-rights provisions with counsel, rather than changing the printed sentence casually or treating the investor's contribution as the authorized-share number. This example illustrates a document mismatch, not a recommendation about how many shares to authorize.

Articles, bylaws and similarly named documents

Articles of incorporation and a certificate of incorporation can perform the same formation function in different states. “Corporate charter” is also used for a corporation's foundational document; check the actual document and state context rather than relying on the label alone.

Bylaws address the corporation's internal governance. They are not a replacement for filing the articles. California expressly says that bylaws are maintained by the entity and are not filed with the Secretary of State.

An LLC uses its own formation document, commonly called articles of organization or a certificate of formation. California's LLC formation route is Articles of Organization—CA LLC. An LLC operating agreement addresses the LLC's internal affairs; California says it is retained by the entity rather than filed with the Secretary of State. Filing corporate articles would not be the correct way to form a California LLC.

A certificate of status or good standing is different again. It reports the entity's status under the issuing agency's criteria. A certified copy authenticates a copy of a particular filed document. If a bank asks for “incorporation papers,” ask whether it needs the formation document, a certified copy, current status evidence or a combination. Sending a status certificate alone may not answer a request to inspect the actual articles.

Mistakes to catch before submission

Check the proposed filing in this order:

  1. Entity and form: Confirm the formation state and whether this is a general stock, nonprofit, professional or other corporation. For an LLC, use the LLC route.
  2. Name and addresses: Review the state's naming requirements and every address field separately. California ARTS-GS prohibits a P.O. box for the initial corporate street address and for an individual agent's California street address.
  3. Agent: Select the correct individual or corporate-agent fields. California's form tells filers using a registered corporate agent to provide its name in the corporate-agent field, rather than also completing the individual-agent fields.
  4. Shares and purpose: Complete required stock information and use a form consistent with the intended classes and activities. Do not copy a general stock purpose clause into a charity's document without checking its needs.
  5. Execution and submission: Obtain the required incorporator signatures, include the applicable fee and required accompanying material, and retain the submission record. Delaware's filing instructions call for a cover sheet when mailing a submission.
  6. Acceptance and effectiveness: Read the filing acknowledgement, filed copy and any rejection notice. Correct the stated defect through the agency's process; do not assume a payment receipt proves acceptance.

These checks are based on actual form requirements and identify preventable filing defects. They are not statistics about the most frequent rejection reasons. A document can also need legal revision even if the filing office accepts it: administrative acceptance is not a personalized legal or tax review.

What should stay out of the public filing

Provide the information the law and correct form require. Before adding optional material, ask whether it belongs in the formation document and whether you are prepared for it to appear in a public record.

Do not volunteer Social Security numbers, bank credentials, passwords, confidential business plans or an entire internal agreement in the articles. This is an editorial privacy precaution, not a claim that a state will automatically redact whatever you submit. Required business, agent or incorporator addresses can themselves be publicly accessible; privacy concerns do not excuse omitting required information.

California's public-record guidance makes another limit clear: its Secretary of State does not maintain a company's shareholder and ownership information as the company's ownership record. Do not treat the incorporator's name or a filed director's name as a complete ownership list.

For a nonprofit seeking federal charitable exemption, generic business-purpose wording can create a separate problem. The IRS organizing-document requirements require appropriate exempt-purpose limits and permanent dedication of assets to exempt purposes. A dissolution provision is a usual way to establish that dedication, although the IRS recognizes that qualifying state law can supply it in certain situations. State incorporation alone does not establish federal tax exemption.

How to find a filed copy

First identify the state where the corporation was formed, its exact legal name and, if available, its entity number. Then use that state's official business-records service. A similarly named company or a registration in another state may lead to the wrong record.

California's Business Entities Records Request guide explains how to obtain free plain copies, certified copies and certificates of status through bizfile Online. Select the formation filing, then look for later amendments or restated articles if you need the current terms. An original filed copy may not show subsequent changes.

For Delaware, the Division of Corporations' formation guide links to its document filing and certificate request service. The stock template's instructions explain that a filed stamped copy is returned and that certification may be requested separately. Do not assume every state's free entity-name search also supplies every document image for free.

Before ordering, confirm what the recipient requires: a readable plain copy, a certified copy of the formation document, amendments, or a current status certificate. If the record is missing or the name has changed, ask the filing agency how to locate the historical document rather than concluding the corporation never existed.

Frequently asked questions and the next filing step

Are articles and a certificate of incorporation the same? They can be different state names for the corporate formation document. Check the issuer: a certificate of status is not the same thing, and an LLC's certificate of formation concerns a different entity type.

Do articles include the bylaws? They serve different purposes. In California, bylaws are maintained internally rather than filed with the Secretary of State. Obtain them from the corporation when you need its internal governance rules.

What are the disadvantages of incorporating? Incorporation can bring continuing reporting, tax and governance obligations, as well as formation costs. The liability and tax effects depend on the circumstances; a corporation is not automatically preferable to an LLC or another structure. Delaware's formation guide, for example, identifies annual reporting and franchise-tax obligations for corporations, with distinctions for exempt corporations.

What should I do next? Choose the formation state and entity type first. For a California corporation or LLC, follow the official entity-type guide to the matching filing route. For a Delaware corporation, use its formation guide and the correct corporate template. For a professional, nonprofit or customized share structure, resolve the special requirements before signing. Then review the current instructions, agent arrangements, fees and proposed effective date; file through the official agency and keep the accepted filed document.
