For many not-for-profit organizations, advancing the mission goes beyond direct services, education, or charitable programs. Sometimes, it also means speaking up on policy issues, rallying supporters, and pushing for broader change. That is one reason some organizations formed under Code section 501(c)(3) (“501(c)(3)s”) consider forming a related entity under Code section 501(c)(4) (“501(c)(4)s”). The structure can create more room for advocacy and lobbying, but it can also bring added complexity and compliance responsibilities.
Taking a close look at both the opportunities and the challenges can help boards and leadership teams decide whether it makes sense for their organization.
What Are 501(c)(3) and 501(c)(4) Entities?
A 501(c)(3) is a tax-exempt charitable organization focused on educational, religious, scientific, or literary purposes. It is eligible for tax-deductible contributions and must avoid engaging in partisan political activity or excessive lobbying.
A 501(c)(4) is a social welfare organization that can engage in advocacy and lobbying, including some types of political activity, so long as those activities further its social welfare purpose. Donations to 501(c)(4)s are not tax-deductible, but these entities offer far greater flexibility for public policy advocacy and political work.
With those distinctions in mind, organizations can better evaluate why a related 501(c)(4) may be appealing and where the structure may create challenges.
Pros of Setting Up a Related 501(c)(4) Entity
For organizations that want to do more in the public policy arena, a related 501(c)(4) can offer meaningful strategic advantages.
Expanded Advocacy and Lobbying Capacit
501(c)(3)s are limited in the amount of lobbying they can do (the “substantial part” test or the 501(h) election) and cannot participate in any political campaigns for or against candidates. A 501(c)(4) can engage in unlimited lobbying and some forms of political activity, allowing the organization to push for policy changes, ballot measures, or issues that may affect its mission.
Ability to Participate in Political Activities
While 501(c)(3)s cannot support or oppose candidates, 501(c)(4)s can, within IRS guidelines, participate in political campaigns as a secondary activity. This opens doors to endorsements, issue advocacy, and grassroots organizing that would be prohibited for charitable organizations.
Mission Synergy
For organizations whose charitable work is closely linked to public policy, a dual structure can help align direct services and educational initiatives with advocacy efforts, amplifying overall impact.
Protecting the 501(c)(3)
By channeling advocacy, lobbying, and political work through a related 501(c)(4), the primary charitable organization can protect its tax-exempt status, reputation, and eligibility for grants and donations, which may be sensitive to political activity.
Cons of Setting Up a Related 501(c)(4) Entity
At the same time, the added flexibility of a dual structure comes with important tradeoffs that organizations should weigh carefully before moving forward.
Complexity and Compliance Burden
Operating a dual structure increases administrative complexity. Each entity must maintain separate books, comply with IRS rules, file distinct tax returns (Form 990 for both), and ensure activities and funds are not improperly commingled. Failure to observe strict separation can risk both organizations’ tax-exempt status.
Funding Challenges
Donations to 501(c)(4)s are not tax-deductible, making fundraising more difficult. Many foundations and institutional donors restrict grants to 501(c)(3)s only. The 501(c)(4) must seek support from individuals, unions, or entities comfortable with non-deductible gifts.
Public Perception Risks
Political and advocacy work, especially tied to electoral campaigns, can be polarizing. Stakeholders or donors may react negatively if the organization’s positions become controversial, potentially impacting the 501(c)(3)’s image and fundraising.
Regulatory Scrutiny
Dual entities involved in political activity attract heightened attention from the IRS and state regulators. The board and management must be vigilant to prevent improper use of charitable funds for political purposes and keep activities clearly separated.
Conclusion
A related 501(c)(4) entity can greatly expand a not-for-profit’s advocacy power and influence. For organizations committed to changing public policy or mobilizing communities, it provides a legal avenue for more robust lobbying and political work. However, the benefits come with increased complexity, fundraising hurdles, and regulatory responsibilities.
Boards considering this structure should carefully assess their mission, consult legal and accounting professionals, and develop clear policies to maintain proper separation. When well-managed, a partnership between a 501(c)(3) and a 501(c)(4) can be a powerful tool for achieving meaningful social change while upholding compliance and transparency.

Frequently Asked Questions
Yes, a 501(c)(3) organization can create a related 501(c)(4) entity. This type of structure is often used when a not-for-profit wants to expand its advocacy or lobbying efforts while helping protect the 501(c)(3)’s tax-exempt status and charitable purpose. However, the two organizations must be operated separately and in compliance with IRS rules.
A related 501(c)(4) can give an organization more flexibility to engage in lobbying, advocacy, and certain political activities that a 501(c)(3) cannot do or can do only in a limited way. This can be especially helpful for organizations whose mission is closely connected to public policy or social change efforts.
The main risks include added administrative complexity, stricter compliance requirements, fundraising challenges, and potential public scrutiny. A 501(c)(3) and a related 501(c)(4) must keep separate books and records, avoid improper sharing of funds, and clearly distinguish their activities to reduce regulatory and reputational risk.
