Nonprofit Lobbying Limits — Excise Tax on Excess Lobbying and Political Activity

Public charities — organizations that hold § 501(c)(3) tax-exempt status — can engage in lobbying, but only to a "substantial" degree. Congress drew a sharp line: lobbying that rises to a "substantial" portion of a charity's activities threatens tax-exempt status under § 501(c)(3). Chapter 41 of the IRC (26 U.S.C. §§ 4911–4912) creates an alternative regime: public charities that make the § 501(h) election get a safe harbor with defined dollar limits, and pay a 25% excise tax on lobbying expenditures that exceed those limits rather than automatic loss of exemption. Separately, § 4912 imposes a 5% tax (on both the organization and responsible managers) if a public charity engages in "substantial" political activity — anything that jeopardizes its exempt status. The absolute prohibition on partisan political activity (electioneering, endorsing candidates) remains: any § 501(c)(3) that crosses that line loses its exempt status entirely, with no excise tax alternative.

Current Law (2026)

Lobbying nontaxable amount (annual limits for § 501(h) electors):

Legal Authority

• 26 U.S.C. § 4911(a) — Imposes a 25% excise tax on the lobbying expenditures of any public charity (that has elected § 501(h)) that exceeds the lobbying nontaxable amount in any taxable year; the tax is paid by the organization on the excess amount
• 26 U.S.C. § 4911(b) — Defines "lobbying expenditures" as the sum of direct lobbying communications plus grassroots lobbying communications; sets the lobbying nontaxable amount as the lesser of $1,000,000 or the sliding-scale percentage of exempt purpose expenditures
• 26 U.S.C. § 4911(c) — Distinguishes direct lobbying (communications with legislators or their staffs that express a view on specific legislation) from grassroots lobbying (communications with the general public that express a view on specific legislation and include a call to action urging recipients to contact legislators)
• 26 U.S.C. § 4911(d) — Exempt activities: expenditures that do not count as lobbying include making available the results of nonpartisan analysis, study, or research; providing technical advice or assistance to a legislative body; communications on legislation affecting the organization's own existence; and examinations or discussions of broad social, economic, and similar problems
• 26 U.S.C. § 4912(a) — Imposes a 5% excise tax on a public charity's total lobbying and political expenditures if the IRS determines that those expenditures cause the organization to no longer qualify as a public charity under § 501(c)(3) due to "substantial" political or lobbying activity
• 26 U.S.C. § 4912(b) — Imposes an additional 5% tax on managers (officers, directors, trustees) who knowingly agreed to make the expenditures that jeopardized the organization's exempt status

Implementing Regulations

The IRS regulations implementing the § 4911 lobbying excise live at 26 CFR Part 56 — Public Charity Excise Taxes. Key provisions:

• § 56.4911-1 — Tax on excess lobbying expenditures: a public charity that has made the § 501(h) election and whose lobbying expenditures exceed the lobbying nontaxable amount for a taxable year owes a 25% excise tax on the excess. The tax is computed annually on Schedule C of Form 990 — organizations report their total lobbying expenditures and compare against their nontaxable amount ceiling. There is no monthly or quarterly payment requirement; the excise is due with the annual Form 990 filing.
• § 56.4911-2 — Definitions: lobbying expenditures, direct lobbying communications, and grassroots lobbying communications. Direct lobbying requires two elements: (1) the communication is with a legislator, legislative staff member, or government official participating in the formulation of legislation; and (2) it expresses a view on specific pending legislation. Grassroots lobbying requires three elements: (1) reference to specific pending legislation; (2) a view on that legislation; and (3) a call to action — directly encouraging, or providing the means for, recipients to contact their legislators. Communications that discuss policy issues without a call to action are not grassroots lobbying even if they are critical of pending legislation.
• § 56.4911-3 — Allocation of expenditures for direct and grassroots lobbying: when a single communication serves both lobbying and non-lobbying purposes (e.g., a policy report that expresses a view on legislation but also contains substantial nonpartisan analysis), the organization must allocate costs between the lobbying portion and the exempt analysis portion. Allocation is based on time spent or other reasonable methodology — the entire cost is not automatically a lobbying expenditure just because the communication contains some advocacy.
• § 56.4911-4 — Exempt purpose expenditures (EPE): the lobbying limit is calculated as a sliding-scale percentage of "exempt purpose expenditures" — roughly, the total cost of carrying out the organization's mission (program services, management, fundraising, but generally not lobbying expenditures themselves). EPE is the denominator in the lobbying ceiling formula. Grants to other organizations count only if specifically earmarked for non-lobbying purposes.
• § 56.4911-5 — Membership communications: communications sent exclusively to an organization's own members are treated more leniently than communications to the general public. A communication to members that refers to pending legislation and expresses a view — but does not include a call to action encouraging members to contact legislators — is not grassroots lobbying, even though it discusses legislation. If the communication does include a call to action directed to non-member legislators, it may qualify as direct lobbying. This safe harbor allows membership organizations to educate their members on legislative issues without immediately triggering the grassroots lobbying meter.
• § 56.4911-6 — Recordkeeping: a § 501(h)-electing charity must maintain records sufficient to demonstrate its lobbying expenditures — time records for staff engaged in lobbying activities, contract amounts for outside lobbyists, and cost allocations for mixed-purpose communications. The records must be retained for three years from the due date of the Form 990 for the year in question.
• §§ 56.4911-7 through 56.4911-10 — Affiliated group rules: multiple § 501(c)(3) organizations controlled by one another (typically through shared board membership or funding control) are treated as an affiliated group for lobbying limit purposes. The group's lobbying expenditures are aggregated and compared against a combined nontaxable amount ceiling — preventing a charity from circumventing limits by routing lobbying activities through subsidiaries or affiliates. Each member of an affiliated group that is a § 501(h) elector is jointly and severally liable for any affiliated group excise tax.

The § 4911 excise functions as a corrective tax rather than a prohibitory penalty — it gives § 501(h)-electing charities a financial consequence for lobbying overruns without revoking their tax-exempt status. By contrast, a non-electing § 501(c)(3) that engages in "substantial" lobbying has no safe harbor and faces direct loss of exemption. This is why the § 501(h) election is virtually always advisable for public charities with any advocacy program.

How It Works

A public charity that makes the § 501(h) election (on Form 5768, filed any time during the tax year) trades the vague "substantial part" test for a clear set of spending limits — and accepts a 25% excise tax on excess lobbying spending rather than risking loss of exemption entirely. The election is revocable and is strongly advisable for most public charities because it provides predictable lobbying room and a financial penalty for minor overages rather than the catastrophic outcome of revocation. The framework distinguishes two types of lobbying: direct lobbying (communicating with a legislator or their staff to express a position on specific legislation — meeting with a senator's office, testifying at a hearing) and grassroots lobbying (contacting the general public via email, social media, or advertising to urge them to contact legislators). Grassroots lobbying is subject to a stricter sub-limit (25% of the direct lobbying allowance) because it can be more politically potent and harder for legislators to trace back to the organization. Importantly, "nonpartisan analysis, study, or research" — publishing policy reports, sponsoring conferences, or creating informational materials about proposed legislation without a call to action — does not count as lobbying at all, giving public charities significant room to engage in policy education.

The absolute prohibition on partisan activity — established by the 1954 Johnson Amendment — bars any § 501(c)(3) organization, including churches, from endorsing or opposing candidates for public office, contributing to political campaigns, or engaging in activities constituting intervention in political campaigns. There is no safe harbor or excise tax alternative for this prohibition: violation means automatic loss of § 501(c)(3) status. Courts have consistently upheld the prohibition as a condition of tax-exempt status rather than a restriction on speech. Private foundations face an even stricter rule: unlike public charities, they face a complete prohibition on lobbying — any lobbying by a private foundation is a taxable expenditure under § 4945, triggering a 20% excise tax on the organization and 5% on foundation managers. This is a major reason large donors use donor-advised funds (which are public charities) rather than private foundations when they want to support advocacy organizations.

How It Affects You

If you run or work for a nonprofit: Make the § 501(h) election if you're a public charity and have any intention of engaging in advocacy. It's a one-page form (5768) and provides enormous benefit: instead of the vague "substantial" test under which any significant lobbying activity could threaten your exemption, you get clear dollar limits and pay a 25% excise tax on overages instead of losing your exemption. Track lobbying expenditures carefully — staff time and outside consultant costs count toward the limits.

If you're a nonprofit board member or officer: Under § 4912(b), you can be personally liable for a 5% excise tax if you knowingly approve expenditures that jeopardize the organization's exempt status. This is one of the few instances in nonprofit law where personal liability attaches to directors. Ensure the organization has a lobbying policy, tracks spending against limits, and has made the § 501(h) election.

If you're a donor to a nonprofit advocacy organization: Your charitable deductions for contributions to § 501(c)(3) organizations are not affected by the organization's lobbying activity as long as it stays within limits. But no deduction is available for contributions to a § 501(c)(4) organization (which can lobby and engage in political activity more freely) — that's a tax-exempt organization but not a charitable one.

If you're a church or religious organization: The Johnson Amendment's prohibition on candidate endorsements applies to you, regardless of how the First Amendment debate plays out. The IRS has rarely enforced it against churches — only one church has had its exemption challenged under the Johnson Amendment — but the legal prohibition is real. Repeated proposals to repeal or narrow the Johnson Amendment (including executive orders) have not been enacted into law. Until Congress acts, any church that endorses a candidate risks its § 501(c)(3) status.

State Variations

Most states have their own nonprofit lobbying registration and disclosure requirements that apply separately from the federal excise tax rules. State lobbying laws typically require nonprofit organizations to register as lobbyists and disclose lobbying expenditures when they exceed thresholds — these obligations apply whether or not the federal IRS limits are exceeded. Registered lobbyists at the state level (whether employed by a nonprofit or a for-profit) must typically file periodic disclosure reports. Some states also restrict lobbying by organizations that receive state grants, creating additional constraints for nonprofits that accept government funding.

Pending Legislation

• Johnson Amendment repeal proposals: Legislation to repeal or narrow the prohibition on nonprofit partisan political activity has been introduced repeatedly (particularly in Republican-controlled Congresses). No bill has passed both chambers as of April 2026. Opponents argue repeal would convert nonprofits into dark money vehicles for political spending; supporters argue it infringes on churches' religious freedom and free speech.
• 501(h) lobbying limit increases: Proposals to raise the dollar caps (maximum $1,000,000 for direct lobbying; maximum $250,000 for grassroots) have been introduced but not enacted. The current maximums were set in 1976 and have not been adjusted for inflation.

Recent Developments

• Johnson Amendment repeal remained a political aspiration but not law (2017–2026): President Trump's 2017 executive order directing the IRS not to enforce the Johnson Amendment against churches was struck down by a federal court as exceeding executive authority. The amendment itself was never changed. In practice, the IRS has not brought an enforcement action for candidate endorsements against a church since 1995, creating a de facto enforcement gap. The Trump administration's second term again raised the possibility of IRS non-enforcement as a priority; as of April 2026, the law remained unchanged and the IRS's published policy had not changed.
• IRS guidance on digital and social media lobbying: The IRS has issued guidance and FAQs clarifying when digital communications — emails, social media posts, website content — constitute grassroots lobbying subject to the § 4911 limits versus nonpartisan public education. Key factors: whether the communication expresses a view on specific legislation (not just general policy), and whether it includes a "call to action" urging recipients to contact their legislators. A social media post describing a bill and providing a link to contact a senator's office is grassroots lobbying. The same information presented without the contact link generally is not. Many advocacy nonprofits restructured their digital communications programs following this guidance.
• IRS increased scrutiny of abusive § 501(c)(3) political activity claims: The IRS, responding to concerns about dark money flows through nominally charitable organizations, has increased scrutiny of § 501(c)(3) applications and existing organizations claiming charitable status for activities that function primarily as political campaign support. Separately, the second Trump administration's IRS leadership signaled interest in revisiting the enforcement posture for nonprofit political activity — including whether certain progressive advocacy organizations qualify for charitable status. As of April 2026, no significant revocation actions had been publicly announced, but the enforcement environment remained uncertain.
• 501(h) lobbying caps haven't been indexed since 1976: The maximum lobbying limit for § 501(h)-electing organizations — $1,000,000 for direct lobbying and $250,000 for grassroots lobbying — was set in 1976 and has never been adjusted for inflation. In 2026 dollars, the real value of these caps is roughly 20% of their 1976 equivalent. Bills to index the caps to inflation have been introduced but not enacted. This means organizations that are lobbying at the same real level as they did in the 1980s may be closer to their nominal limits than they realize.
