Open source software organization denied charitable exemption

Plain-English summary

An organization promoting open source collaboration, standards, software, certifications, and public digital infrastructure applied for exemption under IRC § 501(c)(3). It planned to make software freely available worldwide for any use, with a substantial share of its activities devoted to creating and maintaining that software. The IRS concluded that unrestricted open source software development was a substantial nonexempt purpose because it was not limited to charitable uses or a charitable class. Some training and documentation activities could be educational or charitable, but the substantial nonexempt purpose defeated exemption. The IRS also found inurement because the organization intended to pay a for-profit company controlled by its founder to service the software platform. The organization did not protest the proposed denial, so the IRS issued a final adverse determination.

Ruling snapshot

• Question: Does an organization developing unrestricted open source software and planning to contract with its founder's company qualify under IRC § 501(c)(3)?
• Outcome: Denied because it had a substantial nonexempt software purpose and planned payments that the IRS treated as inurement to the founder
• Key authorities: IRC §§ 501(a), 501(c)(3); Treas. Reg. § 1.501(c)(3)-1(a), (c), (d); Rev. Rul. 71-504; Better Business Bureau of Washington, D.C., Inc. v. United States

Dear :

This letter is our final determination that you don't qualify for exemption from federal income tax under Internal
Revenue Code (IRC) Section 501(a) as an organization described in IRC Section 501(c)(3). Recently, we sent
you a proposed adverse determination in response to your application. The proposed adverse determination
explained the facts, law, and basis for our conclusion, and it gave you 30 days to file a protest. Because we
didn't receive a protest within the required 30 days, the proposed determination is now final.

Because you don't qualify as a tax-exempt organization under IRC Section 501(c)(3), donors generally can't
deduct contributions to you under IRC Section 170.

We may notify the appropriate state officials of our determination, as required by IRC Section 6104(c), by
sending them a copy of this final letter along with the proposed determination letter.

You must file the federal income tax forms for the tax years shown above within 30 days from the date of this
letter unless you request an extension of time to file. For further instructions, forms, and information, visit
www.irs.gov.

We'll make this final adverse determination letter and the proposed adverse determination letter available for
public inspection after deleting certain identifying information, as required by IRC Section 6110. Read the
enclosed Letter 437, Notice of Intention to Disclose - Rulings, and review the two attached letters that show our
proposed deletions. If you disagree with our proposed deletions, follow the instructions in the Letter 437 on how
to notify us. If you agree with our deletions, you don't need to take any further action.

If you have questions about this letter, you can call the contact person shown above. If you have questions

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)(3).
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)(3)? No, for the reasons stated below.

Facts

You were formed as a corporation on B, in the State of C.

Your Form 1023 application states that you exist to promote collaboration and standardization in regard to the
open source ecosystem by bringing together diverse stakeholders to work on best practices and standards. Your
group will focus on creating a space where academia, nonprofits, and the public sector can collaborate on basic
concepts and processes in the open source industry. You have several advisory groups that will be working on
best practices for processes and governance. You will share these best practices under the D license. This will
benefit thousands of open source projects by making them safer. You will share your training and
documentation openly under the D license so anyone can freely use and reuse your work. You will also hold
and be a registry for certifications after best practices and guidelines are established.

Letter 4034 (Rev. 01-2021)
Catalog Number 47628K

While reviewing your application, we sent a request for additional information regarding your activities.

You responded that your operations will consist of several activities, including open source collaboration and
standardization, collaboration on basic processes, workshops and codeathons, registry for certifications, creation
of public digital infrastructure, membership activities, and training and documentation.

When asked if you will be creating open source software, you stated you “will exclusively create open source
software”. You later stated that about x percent of your activities are dedicated to creating and maintaining open
source software. This software will be developed by your community of contributors (developers, designers,
project managers, and other experts) using best practices in open source development. Contributors will include
both volunteers and contracted professionals. You will create the software using public repositories, code
reviews, and continuous integration to ensure quality and security. The documentation of your processes and
collaborations will be publicly available and licensed under the D license, allowing free reproduction and
distribution of the works.

You mandate that all contributors sign a contributor license agreement. This license, aligned with the D license,
is a free, permissive software license that allows users to use, modify, distribute, and create derivative works
from licensed software. All development work will be hosted on your E server, providing a centralized platform
for version control and collaboration. The software will be available to anyone worldwide (free access with no
eligibility requirements). This ensures the software can be freely used, modified, and shared. However, you will
target educational institutions, nonprofits, and public sector organizations. You will also include other open
source nonprofit organizations that wish to discontinue their use of proprietary software.

You have two main categories of platform users. In both cases of users, the software serves various functions
such as improving public digital infrastructure, offering solutions, and providing integrations with other open
source projects.

You are considering being a membership organization. Membership activities would include newsletters,
member-exclusive webinars, and access to a members-only area of your website and associated tools where
resources and forums are available. Members would pay an annual fee, but you also plan to have a no-cost
membership for individuals. Benefits to members may include updates on initiatives, membership summit,
coding competition invitations, collaborative community project opportunities, and discounts on workshop and
certification programs. Members would also be encouraged to contribute to your projects, with opportunities
tailored to their areas of interest.

Currently, a for-profit organization, controlled by your founder, F, is maintaining your platform and covering
any hosting costs as you launch. When funding becomes available, F will participate in the bidding process for
the contract to support your platform. F is also completing a variety of tasks, including administering board
meetings, creating a website, and beginning a community launch and social media outreach plan.

You aim to be supported by grants and donations. You hope to transition to a more financially sustainable
position through program and membership fees within three to five years as you expand your services and
member base. You expect a gradual increase in self-generated income, estimating that program fees and
memberships will contribute approximately y percent to the overall budget. Expenses will include salary, cloud
hosting costs, platform support contracting fees, fundraising costs, and accounting and legal fees.

Law

IRC Section 501(c)(3) provides for the exemption from federal income tax of organizations organized and
operated exclusively for religious, charitable, or other purposes as specified in the statute. No part of the net
earnings may inure to the benefit of any private shareholder or individual.

Treasury Regulation Section 1.501(c)(3)-1(a)(1) states that in order to qualify under IRC Section 501(c)(3), an
organization must be both organized and operated exclusively for one or more of the purposes specified in such
section. If an organization fails to meet either the organizational or operational test, it is not exempt.

Treas. Reg. Section 1.501(c)(3)-1(c)(1) provides that an organization will be regarded as “operated
exclusively” for one or more exempt purposes only if it engages primarily in activities that accomplish one or
more of such exempt purposes specified in IRC Section 501(c)(3). An organization will not be so regarded if
more than an insubstantial part of its activities is not in furtherance of an exempt purpose.

Treas. Reg. Section 1.501(c)(3)-1(c)(2) states that an organization is not operated exclusively for one or
more exempt purposes if its net earnings inure in whole or in part to the benefit of private shareholders or
individuals.

Treas. Reg. Section 1.501(c)(3)-1(d)(2) provides the term “charitable” is used in IRC Section 501(c)(3) in its
generally accepted legal sense and includes relieving the poor and distressed or the underprivileged, combating
community deterioration, lessening neighborhood tensions, and eliminating prejudice and discrimination.

Treas. Reg. Section 1.501(c)(3)-1(d)(3)(i) provides that the term “educational,” as used in IRC Section
501(c)(3), relates to the instruction or training of the individual for the purpose of improving or developing his
capabilities or the instruction of the public on subjects useful to the individual and beneficial to the community.

In Revenue Ruling 71-504, 1971-2 C.B. 231, a city medical society exempt under IRC Section 501(c)(6), that
primarily directs its activities to the promotion of the common business purposes of its members may not be
reclassified as an educational or charitable organization under Section 501(c)(3). The society was created for the
purpose of promoting the art of medicine, the betterment of public health, and the unity, harmony, and welfare
of members of the medical profession. Membership is open to all doctors in the community. Activities included
presentations on new procedures and clinical care, an extensive library of medical books for use by members, a
monthly medical journal, supporting medical education and local health programs, a patient referral service for
members, meetings concerned with matters affecting the promotion and practice of medicine and enhancing and
improving the public image of the medical profession. While some of the society's activities are charitable or
educational, several are instead directed primarily at the promotion of the medical profession and thus further
the common business purposes of its members.

In Better Business Bureau of Washington, D.C., Inc. v. United States, 326 U.S. 279 (1945), the Supreme Court
of the United States interpreted the requirement in IRC Section 501(c)(3) that an organization be “operated
exclusively” by indicating that an organization must be devoted to exempt purposes exclusively. The presence
of a single non-exempt purpose, if more than insubstantial in nature, will destroy the exemption regardless of
the number and importance of truly exempt purposes.

Letter 4034 (Rev. 01-2021)
Catalog Number 47628K

Application of law

You are not described in IRC Section 501(c)(3) because you fail the operational test of Treas. Reg. Section
1.501(c)(3)-1(a)(1). You are not operating “exclusively” for exempt purposes as required by Treas. Reg. Section
1.501(c)(3)-1(c)(1). Creating, maintaining, and providing open source software for anyone to use for any
purpose constitutes a substantial, non-exempt purpose. Your open source software activity is not limited for
charitable purposes or to a charitable class. Your open source software activities are not charitable per Treas.
Reg. Section 1.501(c)(3)-1(d)(2) or educational per Treas. Reg. Section 1.501(c)(3)-1(d)(3)(i). Like the
organization in Rev. Rul. 71-504, you have substantial non-exempt activities. Thus, you are precluded from
exemption under IRC Section 501(c)(3).

Like the organization in Rev. Rul. 71-504, some of your activities may be considered educational or charitable.
However, a substantial portion of your activities involves the creation, maintenance, and provision of open
source software (available worldwide for any individual or organization to use for any purpose) which does not
further “exclusively” exempt purposes. Thus, like the organization in Better Business Bureau, you have a
substantial non-exempt purpose that destroys exemption regardless of the number and importance of truly
exempt purposes.

Further, you intend to pay your founder's organization to service your open source software activities. As
described in Treas. Reg. Section 1.501(c)(3)-1(c)(1), you are not operating exclusively for exempt purposes
because your funds inure to your founder.

Conclusion

Based on the information submitted, you do not qualify for exemption under IRC Section 501(c)(3). You do not
meet the operational test because you are operated for a substantial non-exempt purpose and your funds inure to
your founder.

If you agree

If you agree with our proposed adverse determination, you don't need to do anything. If we don't hear from
you within 30 days, we'll issue a final adverse determination letter. That letter will provide information on
your income tax filing requirements.

If you don't agree

You have a right to protest if you don't agree with our proposed adverse determination. To do so, send us a
protest within 30 days of the date of this letter. You must include:

• Your name, address, employer identification number (EIN), and a daytime phone number

• A statement of the facts, law, and arguments supporting your position

• A statement indicating whether you are requesting an Appeals Office conference

• The signature of an officer, director, trustee, or other official who is authorized to sign for the
organization or your authorized representative

• The following declaration:

For an officer, director, trustee, or other official who is authorized to sign for the organization:

Under penalties of perjury, I declare that I have examined this request, or this modification to the
request, including accompanying documents, and to the best of my knowledge and belief, the request
or the modification contains all relevant facts relating to the request, and such facts are true, correct,
and complete.

Letter 4034 (Rev. 01-2021)
Catalog Number 47628K

Your representative (attorney, certified public accountant, or other individual enrolled to practice before the
IRS) must file a Form 2848, Power of Attorney and Declaration of Representative, with us if they haven't
already done so. You can find more information about representation in Publication 947, Practice Before the
IRS and Power of Attorney.

We'll review your protest statement and decide if you gave us a basis to reconsider our determination. If so,
we'll continue to process your case considering the information you provided. If you haven't given us a basis
for reconsideration, we'll send your case to the Appeals Office and notify you. You can find more information
in Publication 892, How to Appeal an IRS Determination on Tax-Exempt Status.

If you don't file a protest within 30 days, you can't seek a declaratory judgment in court later because the
law requires that you use the IRC administrative process first (IRC Section 7428(b)(2)).
