IRS denies 501(c)(6) business-league status to a group promoting blockchain open-source software
Apply this to your situation

Plain-English summary
A section 501(c)(6) business league is a tax-exempt association of people with a common business interest whose purpose is to improve conditions across a whole line of business, not to run a for-profit-type business or perform particular services for individual members. Here an organization applied for 501(c)(6) status. It was formed and funded (through grants from a related organization) to promote a particular blockchain's open-source software: it advertised members' creations on social media and in a newsletter, gave out free educational materials and courses, ran a chapter/ambassador program, and provided small grants to promote adoption of that software. The IRS determined the group does not qualify. It concluded the organization was organized and operated to promote a specific software ecosystem rather than to improve a line of business, and that it performed particular services for individual members (notably advertising that names members). The IRS relied on the business-league regulation, Revenue Rulings 56-65 and 64-315, and the Ninth Circuit's Bluetooth SIG decision (which denied 501(c)(6) status to an association marketing a wireless protocol). This document is the final adverse determination from the IRS Independent Office of Appeals (the organization waived its right to contest by signing a closing agreement), with the earlier proposed adverse determination letter attached. The takeaway: promoting a single product or software platform, and advertising individual members, is not the same as improving an entire line of business, and it will not support 501(c)(6) exemption.

Dear
We considered your application for recognition of exemption from federal income tax under Internal Revenue Code (IRC) Section 501(a). We determined that you don't qualify for exemption under IRC Section 501(c)(6). This letter explains the reasons for our conclusion. Please keep it for your records.
Issues
Do you qualify for exemption under IRC Section 501(c)(6)? No, for the reasons stated below.
Facts
You were formed on M in N. Your Articles of Incorporation state your purposes are to provide resources, support and education for the development and benefit of the T protocol, ecosystem, and community.
Your application Form 1024 states you are funded by grants from S. S is an organization committed to advancing the T community and T blockchain. The T blockchain is an open-source platform available for any user to learn to use through training provided by you and other similar organizations.
Your mission is to promote the T blockchain ecosystem open-source software by providing resources to various communities all over the world with financial, educational, and technical support. You helped communicate needs to developers regarding the community in need via publications which included new developments delivered through social media channels. You indicated that your methods of communication helped members with limited financial resources to publicize and promote their creations. You gave every builder a voice in the T blockchain ecosystem open-source software, and you furnished free educational materials and helped develop free educational courses to teach the T blockchain ecosystem open-source software. You provided small grants to various community leaders and funded open-source projects which were impactful in promoting the T blockchain ecosystem open-source software.
Letter 4034 (Rev. 01-2021)
Catalog Number 47628K
You stated your common business interest is to have more people use the T blockchain ecosystem open-source software because their businesses are built using this software. You advocate and teach community members who already use this system to become better advocates. You directly improve your members' business conditions by bringing them more potential customers and create open dialogue on best practices of how to use this software and any ethical concerns. You provide free educational materials on how to build, use and interact with this software. You strongly advocate for the T open-source software ecosystem because your members' business interests heavily target these users who do and do not use it. You advocate for the entire T open-source software ecosystem.
You have a chapter/ambassador program which helps you identify leaders, and you provide them with the necessary resources (educational, financial, and technical) to host events in their communities to promote the T blockchain ecosystem open-source software. Every community has different wants and needs so you empower local community leaders to build and expand the T blockchain ecosystem open-source software one community at a time. No matter the location, anyone can join the open-source software community because you have no geographical limitations. You will continue to identify community leaders all over the world to build chapters that promote the T blockchain ecosystem open-source software.
You help each T community with communication needs. You bridge the communication gaps with the communities by having developer teams attend to the needs of each community. You help alleviate the navigation hurdle of communication for newcomers of the T blockchain ecosystem open-source software through publishing new developments via social media channels, publishing weekly articles on various sites, podcasts and talk radio, that are distributed throughout each community. This promotes your stated non-profit activity by helping those with limited financial resources publicize and promote their creations, to bridge the communication gap, and to give every builder a voice in the T blockchain ecosystem open-source software.
You promote the T blockchain ecosystem open-source software by building communities that rely on this software. They use various applications that are created such as decentralized applications, games, art, finance, and technical products. When community members and leaders build or create such items as these that utilize the T blockchain ecosystem open-source software, you help promote members' creations through advertisements, social media channels, and in-depth articles that talk about these products. You further help promote these products by making it known that this software is used for these creations via your weekly publicized newsletter. You support various hackathons to help promote T blockchain ecosystem open-source software. You incubate new creations that take place on the T blockchain ecosystem software. You also provide free T clothing, digital material, including high resolution logos, and promotional material to all community members. This activity helps those who may not have the financial resources to publicize or promote their own creations. It bridges the communication gap and gives every builder a voice in the T software.
Law
IRC Section 501(c)(6) provides exemption from federal income tax for business leagues, chambers of commerce, real-estate boards, boards of trade, or professional football leagues, (whether or not they administer a pension fund for football players), not organized for profit and no part of the net earnings, of which, inures to the benefit of any private shareholder or individual.
Treasury Regulations Section 1.501(c)(6)-1 states that a business league is an association of persons having some common business interest, the purpose of which is to promote such common interest and not to engage in
Letter 4034 (Rev. 01-2021)
Catalog Number 47628K
a regular business of a kind ordinarily carried on for profit. It is an organization of the same general class as a chamber of commerce or board of trade. Thus, its activities should be directed to the improvement of business conditions of one or more lines of business as distinguished from the performance of a particular service for individual persons. An organization, whose purpose is to engage in a regular business of any kind ordinarily carried on for profit, even though the business is conducted on a cooperative basis or produces only sufficient income to be self-sustaining, is not a business league.
Revenue Ruling 56-65, 1956-1 C.B. 199, holds that a local organization whose principal activity consists of furnishing particular information and specialized individual services to its individual members engaged in a particular industry, through publications and other means to effect economies in the operation of their individual businesses, is performing particular services for individual persons. Such organization is not entitled to exemption under Section 501(c)(6) of the Code as a business league, even though it performs functions that are of benefit to the particular industry and the public generally.
Revenue Ruling 64-315, 1964-2 C.B. 147 An association of merchants whose businesses constitute a shopping center expends its funds and engages exclusively in advertising in various newspapers and on television and radio in order to attract customers to the shopping center. This advertising contains the names of member merchants and their merchandise. Held, the organization is not entitled to exemption from Federal income tax as an organization described in section 501(c)(6).
In Bluetooth SIG, Inc. v. United States, 611 F.3d 617 (9th Cir. 2010), the Ninth Circuit Court of Appeals held that an association that owned and marketed a wireless networking protocol and trademark was not exempt under I.R.C. § 501(c)(6) because it engaged in a business ordinarily conducted for profit, it did not improve the conditions of one or more lines of business, and it provided particular services for members.
Application of law
You are not described in IRC Section 501(c)(6) because you are primarily organized and operated to promote the T blockchain open-source software versus promoting a line of business. You aim to have people using the T blockchain software and in doing so conduct activities to promote, teach and improve members already operating your product. Further, your Articles of Incorporation state in part that your purposes "are to provide resources, support and education for the development and benefit of the T protocol, ecosystem and community". You are not described in Treas. Reg. Section 1.501(c)(6)-1 because you are primarily conducting activities to promote the T blockchain ecosystem open-source software instead of improving a line of business.
You are similar to the organization described in Revenue Rulings 56-65 in that you serve the private interests of your members by performing particular services for them such as advertising their creations through your social media channels and your weekly newsletter, providing free educational materials on how to build, use and interact with the T blockchain open-source software ecosystem, and attending events to advocate for this system. An organization that furnishes particular information and specialized individual service to its members through publications and other means to effect economies in the operation of their individual businesses is performing particular services to its members rather than directing your activities to the improvement of business conditions of a particular industry as a whole.
Further, you are promoting members' creations through advertising/promotion and social media. Although this is not your sole activity, advertising that carries the names of members generally constitutes the performance of
Letter 4034 (Rev. 01-2021)
Catalog Number 47628K
particular services for members. See Revenue Ruling 64-315, when advertising contained the names of member merchants the organization was found to not qualify under IRC Section 501(c)(6).
You are similar to the organization in Bluetooth SIG, Inc. v. United States, Inc, because your activities do not improve the business conditions of one or more lines of business in any community. Instead, you serve the private interests of your members and perform particular services for them by advocating and promoting the T software. Your activities promote the T blockchain ecosystem open-source software by building communities that rely on this software — those that have built with and use your software learn how to better operate their businesses through your activities versus the improvement of business conditions as a whole.
Conclusion
Your activities are not directed to the improvement of business conditions of one or more lines of business, or any other purpose defined in IRC Section 501(c)(6). Your activities consist of rendering particular services to members. Therefore, you fail to qualify under Section 501(c)(6).
