Advocacy and Lobbying: What Nonprofits Can Do and What the Rules Say

A widespread misconception in the nonprofit sector holds that 501(c)(3) organizations cannot engage in political advocacy or lobbying. This misconception causes many nonprofits to forgo significant and legally permitted tools for advancing their missions, leaving policy change work to others while focusing exclusively on direct service. Understanding what nonprofit organizations can actually do under federal tax law and the rules that govern political activity is essential for any mission-driven organization trying to create systemic change. The Internal Revenue Code distinguishes between several types of political activity for tax-exempt purposes. Lobbying, which involves direct or grassroots communication with legislators about specific legislation, is permitted for 501(c)(3) organizations but subject to limits. Political campaign activity, which involves supporting or opposing candidates for public office, is prohibited for 501(c)(3) organizations. These are distinct categories with different rules, and the distinction matters enormously for how organizations design their advocacy work. Public charity 501(c)(3) organizations must not devote a substantial part of their activities to lobbying, though the definition of substantial is ambiguous unless an organization makes the 501(h) election. The 501(h) election allows eligible public charities to use bright-line dollar limits rather than the vague substantiality test to define permissible lobbying. Under 501(h), organizations can spend a set percentage of their exempt purpose expenditures on lobbying, with separate limits for direct lobbying of legislators and grassroots lobbying of the public about legislation. For most nonprofits, the dollar limits under 501(h) are generous enough to accommodate substantial advocacy work. Many nonprofits have not made the 501(h) election despite its advantages, often because their legal counsel has not explained it clearly or because internal caution leads organizations to underestimate what the law permits. Organizations that have made the election can engage in significant legislative advocacy without putting their tax-exempt status at risk, as long as they track their lobbying expenditures and stay within the applicable limits. Nonpartisan voter registration, civic education, and get-out-the-vote activities are generally permitted for 501(c)(3) organizations as long as they are conducted without reference to specific candidates or parties. Voter registration drives, candidate forums that present candidates equally, and civic education about how government works are all activities that tax-exempt organizations can conduct. These activities build civic participation in ways that advance many organizations' missions and do not require the restrictions that direct electoral advocacy does. 501(c)(4) social welfare organizations, which can engage in substantial lobbying and some electoral activity as long as their primary purpose is social welfare rather than electoral work, are a related organizational form that some nonprofits use alongside their 501(c)(3) entities for purposes that go beyond what the charitable tax exemption permits. 501(c)(6) trade associations and 501(c)(5) labor organizations have similar flexibility. Creating and maintaining affiliated organizations with different tax structures requires careful governance and legal advice but opens up advocacy options. Beyond the legal framework, the strategic case for nonprofit advocacy is compelling. Policy change multiplies the impact of direct service work: an organization that helps individual clients navigate a broken system while also working to fix the system itself achieves much more than one focused exclusively on individual cases. Research on the policy change process documents that nonprofits, particularly those representing affected communities directly, play significant roles in moving policy agendas, providing expert testimony, and holding implementing agencies accountable. Advocacy capacity building in the sector is an area where foundations can have significant leverage. Many nonprofits lack the internal capacity to engage effectively in policy processes: they do not have staff with policy expertise, relationships with lawmakers and agency officials, or organizational cultures that support advocacy engagement. Funders who support capacity building for advocacy, including training, staffing, and coalition participation, enable more effective policy influence by their grantees. Coalition advocacy, in which multiple organizations coordinate their advocacy efforts around shared policy priorities, is generally more effective than isolated organizational advocacy. Coalitions bring broader representation, pooled resources, and the ability to present a unified front to policymakers. Managing coalitions requires deliberate attention to power dynamics, shared decision-making processes, and the distinct interests and constraints of different member organizations. Coalitions that are genuinely representative of affected communities tend to be more credible and more durable than those that represent primarily professional advocates.
