Nonprofit Entity’s Lodge System: 501(c)(8) and 501(c)(10)

A nonprofit that operates under the lodge system is a fraternal organization built around a parent body and one or more chartered local chapters, and it qualifies for federal tax exemption under either Section 501(c)(8) or Section 501(c)(10) of the Internal Revenue Code. Which section applies turns on a single question: does the organization provide life, sick, accident, or similar benefits to its members? If yes, it falls under 501(c)(8). If no, and its earnings go to religious, charitable, educational, or fraternal purposes, it falls under 501(c)(10). Familiar examples include the Elks, the Moose, the Knights of Columbus, the Freemasons, and the Shriners.

What the IRS Means by a Lodge System

The IRS looks for at least two real, functioning entities: a parent organization and at least one subordinate unit, usually called a lodge, chapter, or branch. The subordinate has to be chartered by the parent and largely self-governing, and both have to actually operate. A constitution that authorizes local chapters on paper is not enough.¹

Courts have added shape to the definition. A lodge system holds regular meetings at a set location, uses a representative form of government, and carries out its work according to a ritual. That ritual piece is what distinguishes a fraternal lodge from other hierarchical nonprofits.²

There is also a fraternal purpose requirement. Membership must rest on a common tie or shared pursuit, and the organization must maintain a substantial program of fraternal activities. A group that collects dues and holds one dinner a year probably falls short.¹

501(c)(8) or 501(c)(10): Which One Applies

Section 501(c)(8): Fraternal Beneficiary Societies

A fraternal beneficiary society qualifies under 501(c)(8) if it operates under the lodge system and provides life, sick, accident, or other benefits to its members or their dependents. Think of it as a mutual-aid function layered onto the fraternal one. The benefits requirement is not decorative. Most members must be eligible, and any rules that exclude certain members from benefits have to be reasonable. An organization that provides benefits to only a handful of people will not qualify.¹

A 501(c)(8) organization can administer benefits directly or set up a separate entity that provides benefits exclusively for its members. Some lodges arrange optional insurance through outside insurance companies rather than self-funding coverage.³

Section 501(c)(10): Domestic Fraternal Societies

A domestic fraternal society qualifies under 501(c)(10) if it operates under the lodge system, does not provide life, sick, accident, or other benefits, and devotes its net earnings exclusively to religious, charitable, scientific, literary, educational, or fraternal purposes. “Domestic” means what it says: the organization has to be organized in the United States. That requirement does not appear in 501(c)(8).⁴

The word “exclusively” is strict. Every dollar of net earnings has to go toward the specified purposes. A 501(c)(10) lodge can still arrange for an outside insurance company to offer optional coverage to members without losing its status, as long as the lodge itself is not the one providing the benefits.¹

Are Donations to a Lodge Tax-Deductible?

Sometimes. Contributions to a fraternal organization operating under the lodge system are deductible only when the money is earmarked for religious, charitable, scientific, literary, or educational purposes, or for preventing cruelty to children or animals. General dues and gifts to the lodge’s operating fund do not qualify.⁵

The rule applies to both 501(c)(8) and 501(c)(10) organizations. Many lodges maintain a separate charitable fund so that donors have a clean way to direct deductible gifts toward qualifying activities.⁶

Taxes the Lodge Still Pays

Exemption is not immunity. A tax-exempt lodge remains subject to tax on unrelated business income under Section 501(b). If the lodge earns revenue from activities that are not substantially related to its fraternal or charitable purpose, that income is taxed at regular corporate rates. Renting the hall out to the public, running a bar open to non-members, and operating a parking lot are common examples.⁷

A lodge with more than $1,000 in gross unrelated business income has to file Form 990-T and pay the tax. Smaller lodges that treat hall rentals as just another way to cover expenses sometimes miss this.

Applying for Recognition

A fraternal organization seeking recognition under 501(c)(8) or 501(c)(10) files Form 1024, Application for Recognition of Exemption. Filing is electronic through Pay.gov: register for a Pay.gov account, search for “1024,” and complete the form online.⁸

A parent organization with several subordinate lodges has another route. Under Revenue Procedure 2026-8, a central organization can apply for a single group exemption letter that covers all of its subordinates, so each local chapter does not have to file its own application. The central organization needs at least five subordinates to obtain the initial group exemption, and it applies on Form 8940 through Pay.gov.⁹

Holding a group exemption letter is not a set-and-forget arrangement. The parent has to annually collect and review financial and compliance information from each subordinate and educate subordinates about maintaining their exempt status each year. Every subordinate included in the group exemption must authorize the central organization in writing and acknowledge that the parent can remove it with or without cause.⁹

Annual Filings and the Three-Year Trap

Every exempt fraternal organization has to file something with the IRS each year. Which form depends on size:

Form 990-N, the e-Postcard, for organizations with gross receipts normally $50,000 or less. It is a brief electronic notice, not a full return.
Form 990-EZ for organizations with gross receipts under $200,000 and total assets under $500,000.
Form 990 for organizations with gross receipts of $200,000 or more, or total assets of $500,000 or more.

¹⁰

The return is due by the 15th day of the fifth month after the organization’s tax year ends, which is May 15 for calendar-year filers. Under Section 6033(j) of the Internal Revenue Code, an organization that fails to file for three consecutive years automatically loses its tax-exempt status. Revocation takes effect on the filing due date of the third missed year. No grace period. No discretionary review. The IRS publishes a list of every organization whose exemption has been revoked this way.¹¹

A lodge that loses its exemption this way has to file a new application to get it back. Retroactive reinstatement is possible, but only if the organization can show the IRS reasonable cause for the missed filings. Until exemption is restored, the lodge may owe corporate income tax on its earnings. For small lodges with volunteer treasurers, this is where things most often go wrong. The e-Postcard takes minutes, but forgetting it three years running is easy when nobody is tracking the date.¹¹
