To form an unincorporated association, two or more people agree to pursue a shared nonprofit purpose, pick a name and leaders, write down the rules in a governing document, get a federal Employer Identification Number so the group can open its own bank account, and—if the money involved justifies it—apply to the IRS for tax-exempt status. There is no state incorporation filing and no formation fee. The structure is the easiest nonprofit vehicle to stand up, and the one with the fewest built-in protections, so the work is less about paperwork and more about getting the internal agreements and the liability picture right before the group starts signing contracts or collecting money.
Settle the Basics Before You Write Anything
Start with the founding members in a room, and settle three things.
Pick a name. It should be distinct enough that people won’t confuse your group with an existing organization in the same area. A quick online search and a check of your state’s business name database will flag the obvious conflicts.
Define the purpose. Keep it specific enough to guide future decisions. “Promote community gardening in the west side neighborhoods” is more useful than “do good things.” The purpose statement will show up in your governing document, any tax filings, and any application for exempt status, so get it right now rather than rewriting it later.
Agree on leadership. Most associations start with a president or chair, a secretary, and a treasurer. Decide how long each officer serves, how elections work, and what happens if someone resigns mid-term. The details matter less at the first meeting than the fact that you discussed them; groups that skip this conversation tend to hit power struggles once the association grows.
Put the Rules in Writing
The group’s agreements belong in a written governing document, usually called bylaws or a constitution. It functions as a contract among the members. In most states, you do not file it with any government agency, though a handful of states do require certain filings for an association to gain limited liability protection. Even where no filing is required, a signed document gives every member one place to look when there’s a dispute.
A solid governing document covers at least:
- Name and purpose, stated plainly.
- Membership: who can join, how they apply, what rights members have, and the process for removing someone.
- Officers and elections: which positions exist, what each does, how long terms last, and how elections run.
- Meetings: how often the group meets, how members are notified, and the quorum needed to make binding decisions.
- Finances: how dues are set and collected, who can authorize spending, and how the treasurer reports to the membership.
- Amendments: the exact procedure for changing the document, including the vote threshold.
- Dissolution: what happens to the group’s money and property if the association shuts down.
If you plan to seek federal tax-exempt status, add a conflict-of-interest policy. The IRS Form 990 asks whether your organization has one, and it expects the policy to require members with a potential conflict to disclose it and to bar them from voting on any matter where the conflict exists. Writing it in now is easier than retrofitting it during a tax application.
Get an EIN and Open a Bank Account
An Employer Identification Number is a nine-digit federal tax ID the IRS assigns to organizations for tax filing and reporting. Even if your association has no employees and no immediate plans to pursue tax-exempt status, you need an EIN to open a bank account in the group’s name, and keeping group money separate from personal accounts is the bare minimum of financial accountability.
You can apply online through the IRS website at no cost, and the number is typically issued immediately.1Internal Revenue Service. About Form SS-4, Application for Employer Identification Number The underlying form is Form SS-4, but the online application walks you through the questions without the paper version. You will need the association’s name, a physical address, and the name and taxpayer identification number of a “responsible party,” the person the IRS will contact about the account.2Internal Revenue Service.

Bring the EIN to a bank along with a signed copy of your governing document. Many banks also ask for minutes from a meeting authorizing the account and designating who can sign checks. Call ahead; documentation expectations vary.
Decide Whether to Apply for Tax-Exempt Status
An unincorporated association can qualify for federal tax-exempt status under several sections of the Internal Revenue Code, including 501(c)(3) for charitable and educational organizations and 501(c)(7) for social and recreational clubs.3Internal Revenue Service. Creating an Exempt Organization Whether you need to formally apply depends on how much money the group brings in.
Organizations with annual gross receipts normally above $5,000 must notify the IRS that they are seeking tax-exempt recognition. Without that notification, the IRS will not treat the organization as exempt.4Office of the Law Revision Counsel. 26 USC 508 – Special Rules With Respect to Section 501(c)(3) Organizations Groups that stay below that threshold and are not private foundations are exempt from this notification requirement, though they can still apply if they want a formal determination letter.
Smaller associations seeking 501(c)(3) status can use the streamlined Form 1023-EZ. To qualify, the organization must project annual gross receipts of $50,000 or less for each of the next three years, must not have exceeded $50,000 in any of the past three years, and must hold total assets valued at $250,000 or less.5Internal Revenue Service. Instructions for Form 1023-EZ Larger organizations use the full Form 1023.
Annual Filings You Can’t Skip
Once recognized as tax-exempt, the association files annually. Small organizations with gross receipts normally at or below $50,000 satisfy the requirement by filing Form 990-N, a brief electronic notice called the e-Postcard.6Internal Revenue Service. Annual Electronic Filing Requirement for Small Exempt Organizations – Form 990-N (e-Postcard) Larger organizations file Form 990 or Form 990-EZ.
Don’t ignore these filings. An organization that fails to file for three consecutive years automatically loses its tax-exempt status, with revocation effective on the due date of the third missed return. Once revoked, the organization owes federal income tax on its earnings and can no longer receive tax-deductible contributions.7Internal Revenue Service. Automatic Revocation of Exemption Reinstating exempt status requires a new application and, depending on the circumstances, paying any back taxes owed during the gap.
Understand Personal Liability Before You Sign Anything
This is where unincorporated associations differ most sharply from corporations and LLCs, and it is the single most important thing to understand before choosing this structure. In most states, an unincorporated association is not treated as a legal entity separate from its members. If the group takes on a debt it cannot pay, or if someone is injured during a group activity and sues, individual members and officers can be held personally responsible. Personal bank accounts, homes, and other assets are potentially at risk.
The exposure is broad. Contractual obligations the group signs, such as a venue lease, a catering order, or an equipment purchase, are generally treated as joint obligations of the members. If the association’s funds cannot cover a judgment or a bill, creditors can pursue the individuals who authorized the commitment, and in some cases the general membership.
Check Whether Your State Offers a Shield
A growing number of states have adopted some version of the Uniform Unincorporated Nonprofit Association Act, which treats the association as a separate legal entity and shields members from personal liability for the group’s debts solely because of their membership. In those states, a judgment against the association is not automatically a judgment against individual members or officers, and the protection survives a failure to observe corporate-style formalities—a common trap for small volunteer-run groups.
Not every state has adopted the act, and the details vary among those that have. Confirm whether your state recognizes unincorporated associations as separate entities before assuming you have any liability shield.
Insurance as the Practical Backstop
Whatever your state’s law says, a general liability policy is worth investigating once the association starts holding events, handling money, or interacting with the public. Coverage can be harder to obtain for an unincorporated association than for a corporation, because insurers sometimes struggle to identify exactly who is being covered, but it remains the most reliable way to limit personal financial exposure.
Write In a Dissolution Clause Now
The dissolution clause in your governing document is easy to overlook at formation and painful to improvise later. It should spell out how the group votes to shut down—typically a supermajority of the membership—and what happens to any remaining money and property. If the document is silent, the process can require unanimous consent or a court proceeding, depending on state law.
For associations that later obtain 501(c)(3) status, remaining assets generally must go to another tax-exempt organization rather than back to individual members. Naming the recipient, or at least the method for choosing one, in the clause itself prevents arguments at the worst possible moment. Tax-exempt groups that dissolve also have to notify the IRS on their final return.8Internal Revenue Service. Termination of an Exempt Organization
