Nonprofit Bylaws vs. Articles of Incorporation

Articles of incorporation are the public document a nonprofit files with its state to legally create the corporation, including the IRS-required purpose and dissolution clauses; bylaws are the organization's private internal rulebook for how the board operates, which is not filed with the state. Both are typically required to apply for 501(c)(3) status, but they serve different legal purposes and are amended through different processes.

Key Takeaways

  • Articles of incorporation create the entity

    Filing articles of incorporation with the state's filing office is the act that legally creates the nonprofit corporation; without it, there is no entity for bylaws to govern.

  • Bylaws govern how the entity runs day to day

    Bylaws set out board size and terms, meeting and voting procedures, officer roles, and committee structure, none of which are typically included in the articles of incorporation.

  • One is public, the other usually is not

    Articles of incorporation are filed with the state and become a public record; bylaws are an internal governing document that is not filed with the state and is not normally public.

  • The IRS cares most about the articles for the organizational test

    The IRS's organizational test for 501(c)(3) status is based on the articles of incorporation, including their required purpose and dissolution clauses, though the IRS also asks to see a copy of the bylaws as supporting documentation.

  • Amending each document works differently

    Changing the articles of incorporation generally means filing an amendment with the state and paying its fee; changing bylaws is usually an internal board vote under whatever amendment procedure the bylaws themselves set out, with no state filing.

Comprehensive Guide

Two Documents, Two Different Jobs

Every nonprofit corporation has at least two foundational documents: articles of incorporation and bylaws. They are often prepared around the same time, and both typically get submitted to the IRS with a 501(c)(3) application, but they are not interchangeable, and each does a job the other does not.

Articles of Incorporation: Creating the Legal Entity

Articles of incorporation are the document filed with a state's filing office, such as the Secretary of State, that legally brings the nonprofit corporation into existence. They typically include the organization's name, its registered agent and registered office, and the required purpose and dissolution clauses that satisfy the IRS's organizational test for 501(c)(3) status. Because this document is filed with the state, it becomes part of the public record, searchable the same way a for-profit corporation's formation documents are.

Bylaws: Running the Organization Day to Day

Bylaws are the nonprofit's internal rulebook, adopted by the board after incorporation rather than filed with the state. They typically cover board size and how directors are elected or removed, how often the board and any committees meet, quorum and voting rules, officer titles and duties, and the procedure for amending the bylaws themselves. None of this operational detail usually appears in the articles of incorporation, and states generally do not require it to.

Why Both Matter for 501(c)(3) Status

When you apply for federal tax exemption, the IRS's organizational test looks specifically at your articles of incorporation to confirm the required purpose and dissolution language is present. Separately, the IRS also asks applicants to submit a copy of their bylaws as part of the application, mainly to understand how the organization is actually governed, even though the bylaws themselves are not what the organizational test is checking. An application is generally expected to include both documents, serving these two different functions.

Public Record vs. Internal Document

Because articles of incorporation are filed with the state, anyone can typically look them up through the state's business entity search. Bylaws, by contrast, are an internal document the organization keeps itself; they are not filed with the state and are not part of the public business entity record, though a grantmaker or major donor may sometimes ask to see a copy as part of due diligence.

Amending Each Document

Changing the articles of incorporation, such as updating the organization's name or registered agent, generally requires filing a formal amendment with the state's filing office and paying its fee. Changing the bylaws is usually simpler: most bylaws include their own amendment procedure, commonly a vote of the board at a regular or special meeting, with no state filing or fee involved. This difference is one of the most practical reasons to put operational detail that may change often, such as the exact number of board meetings per year, in the bylaws rather than the articles.

What Happens if They Conflict

If a provision in the bylaws conflicts with something in the articles of incorporation, or with the state's nonprofit corporation act itself, the articles and the underlying statute generally control, since the articles are the organization's foundational legal document and the bylaws operate beneath it. Keeping both documents reviewed together when you make a significant governance change helps avoid this kind of conflict before it becomes a problem.

Practical Considerations

Keep Both Documents in the Same Place

Banks, grantmakers, and your own board will ask for one or both of these documents repeatedly. Keep an up-to-date copy of both the filed articles of incorporation and the current bylaws together, rather than treating them as separate records kept by different people.

Review Bylaws More Often Than Articles

Because bylaws cover day-to-day governance, it's reasonable to revisit them every few years, or after a significant change like growing board size, while articles of incorporation typically only need updating when something fundamental changes, such as the organization's name or registered agent.

A State Amendment Doesn't Update Your Bylaws Automatically

If you amend your articles of incorporation, check whether anything in your bylaws references the old language, such as an outdated organization name or address, since updating one document does not automatically update the other.

Don't Let Bylaws Drift From Actual Practice

If your board has stopped following a specific bylaws provision, such as a stated number of annual meetings, treat that as a prompt to formally amend the bylaws to match your actual practice, rather than leaving a governing document that doesn't reflect reality.

This Is Not Legal Advice

What belongs in your articles of incorporation versus your bylaws, and how to handle a conflict between the two, can depend on your specific state's nonprofit corporation act. A nonprofit attorney can review both documents together before you file or amend either one.

Frequently Asked Questions

Are nonprofit bylaws filed with the state?

No. Articles of incorporation are filed with the state and become a public record; bylaws are an internal governing document the organization adopts and keeps itself, without filing them with the state's filing office.

Does the IRS require both articles of incorporation and bylaws for a 501(c)(3) application?

Yes, typically. The IRS's organizational test specifically reviews the articles of incorporation for required purpose and dissolution language, and the application also asks for a copy of the bylaws to show how the organization is governed.

Which document is harder to change, articles of incorporation or bylaws?

Articles of incorporation are generally harder to change, since amending them means filing paperwork with the state and paying a fee; bylaws are usually changed through an internal board vote under the bylaws' own amendment procedure, with no state filing.

Can a nonprofit operate with only articles of incorporation and no bylaws?

In practice, no. While bylaws are not filed with the state, nearly every nonprofit adopts them to govern basic matters like board meetings and voting, and the IRS asks to see a copy of the bylaws as part of a 501(c)(3) application.
