Can Your Charity Lobby? The 501(h) Election That Turns a Vague Rule Into a Clear Budget

If you run a small nonprofit, this sentence from the tax code probably keeps you up at night: a public charity loses its exemption if "a substantial part" of its activities is lobbying. How much is substantial? Five percent of your budget? Twenty percent? A few emails to your city council?

The IRS has never defined it. That vagueness causes many charities to do one of two costly things: avoid all advocacy even when speaking up would advance their mission, or lobby freely without tracking anything and hope no one notices.

There is a third option most small charities miss. By filing a simple one-page form, you can swap the vague test for a math formula with dollar limits, clear definitions, and generous ceilings. It is called the Section 501(h) expenditure-test election, and for most public charities it is the single best compliance bargain in the nonprofit tax rules.

Yes, Charities Can Lobby — They Just Cannot Electioneer​

Start with the distinction that confuses almost every new board.

Lobbying is allowed, within limits. A 501(c)(3) public charity can contact legislators, urge the public to contact legislators, and advocate for or against specific bills, as long as the activity is not a substantial part of what it does — or, if it elects under 501(h), as long as spending stays within the dollar limits.

Campaign intervention is banned, absolutely. Supporting or opposing any candidate for public office — endorsements, donations, coordinated voter guides, even a social media post from the organization's account praising a candidate — is prohibited for 501(c)(3)s. There is no de minimis exception and no election that permits it. Violations can cost you exemption fast.

This post is only about the first category: lobbying on legislation and ballot measures. If your question is "can we endorse a mayoral candidate," the answer is no, and no form changes that.

The Default Rule: The Substantial-Part Test Nobody Can Measure​

If you do nothing, the IRS judges your lobbying under the substantial-part test. It is a facts-and-circumstances test that weighs everything: money spent, staff time, volunteer hours, publications, and more.

That breadth is the problem. Under the default test:

• There is no percentage or dollar safe harbor published anywhere.
• Both paid staff time and volunteer time count toward "substantial."
• You report on Form 990 Schedule C, Part II-B with a narrative description of each activity plus volunteer hours and expenditures — essentially asking the IRS to grade your essay.
• If the IRS decides your lobbying was substantial, the penalty is revocation of exemption, applied retroactively in the worst cases.

In practice, very few charities are revoked solely for lobbying. But the uncertainty has a real cost: cautious boards ban all contact with lawmakers, while less cautious ones keep no records and cannot prove they were insubstantial if ever asked.

Congress created the 501(h) election in 1976 precisely to fix this. Filing it replaces the essay exam with arithmetic.

The 501(h) Election: A Bright-Line Lobbying Budget​

File IRS Form 5768 — a one-page notice literally titled "Election/Revocation of Election by an Eligible Section 501(c)(3) Organization to Make Expenditures to Influence Legislation" — and your charity elects to be measured under the expenditure test of Sections 501(h) and 4911 instead.

What changes:

• Only expenditures count. Unreimbursed volunteer activity does not use up your limit.
• The statute defines what counts as lobbying, with specific exceptions.
• Your allowed lobbying is a dollar amount computed from your budget, up to $1 million per year.
• A separate, smaller sublimit applies to grassroots lobbying.
• Exceeding the annual limit in one year triggers a 25% excise tax on the excess — not automatic loss of exemption. You lose exemption only if you normally exceed 150% of the limits over a four-year average.

The form can be filed at any point in the tax year and applies to that year and every later year until you revoke it. There is no user fee and no approval process; you simply file it with the IRS service center listed in the instructions and start tracking under the new rules.

Who Can and Cannot Elect​

Most public charities described in Section 509(a)(1), (2), or (3) — the typical community charity, service provider, arts group, or advocacy organization — are eligible.

Two big groups are not:

• Private foundations cannot elect and generally cannot lobby at all. If a private foundation makes a lobbying expenditure, it owes tax on it.
• Churches, integrated auxiliaries of churches, and conventions or associations of churches (and affiliated groups containing one) cannot elect. They remain under the substantial-part test.

If you are unsure of your public-charity classification, check your determination letter and your most recent Form 990. When in doubt, ask your CPA before filing.

How the Math Works: Your Lobbying Nontaxable Amount​

Your annual overall lobbying limit — the statute calls it the "lobbying nontaxable amount" — is a sliding scale based on exempt purpose expenditures. Think of that as roughly your annual spending to carry out your mission: program costs plus management and general costs plus lobbying itself. Fundraising costs, investment management, and unrelated business expenses are generally excluded, so the base is usually a bit less than total expenses on your audited financials.

The formula in Section 4911(c)(2):

Your grassroots lobbying limit is 25% of the overall lobbying limit. Direct lobbying gets the rest.

Three quick examples:

• $200,000 budget. Lobbying limit: $40,000 (20%). Grassroots sublimit: $10,000. A small charity can fund a real advocacy campaign — staff time drafting a bill analysis, travel to the statehouse, paid ads urging calls to a committee — without coming close.
• $800,000 budget. Lobbying limit: $100,000 + 15% × $300,000 = $145,000. Grassroots sublimit: $36,250.
• $2,000,000 budget. Lobbying limit: $225,000 + 5% × $500,000 = $250,000. Grassroots sublimit: $62,500.

Very few small charities ever approach these ceilings. That is the point: the election gives you room to advocate plus a number you can show your board.

Direct vs. Grassroots: The Two Buckets That Matter​

Under the expenditure test, only two kinds of communications count as lobbying, and they draw from different buckets.

Direct lobbying is a communication with a legislator, their staff, or another government official who participates in formulating legislation, that refers to specific legislation and reflects a view on it. A meeting with your state representative to support a specific housing bill, or a letter to a committee chair opposing a proposed cut, is direct lobbying.

Grassroots lobbying is a communication with the general public that refers to specific legislation, reflects a view on it, and includes a call to action — urging recipients to contact legislators, providing a legislator's contact information or a petition, or providing a mechanism such as a pre-addressed postcard. A mass email saying "tell your council member to vote yes on Ordinance 24-118, call 555-0100" is grassroots lobbying. The same email explaining what the ordinance does, without urging action, generally is not.

Why the distinction matters: grassroots spending is capped at one-quarter of your overall limit, and grassroots overages are tested separately. A charity that stays well under its overall limit can still owe excise tax if it pours everything into public-facing calls to action. Track the two buckets separately from day one.

What Does Not Count Against Your Limits​

The regulations carve out several activities that are not lobbying at all under 501(h), even if they touch on policy:

• Nonpartisan analysis, study, or research made available to the public or to government on a nonpartisan basis. A widely distributed report on homelessness trends with a full and fair exposition of the facts is not lobbying, even if legislators read it. To qualify, the work must not present only one side with an explicit call for legislative action.
• Technical advice or assistance provided to a governmental body or committee in response to a written request. If a committee formally asks your clinic director to explain how a billing rule affects patients, answering is not lobbying.
• Self-defense communications about legislation that could affect your existence, powers, duties, tax-exempt status, or deductibility of contributions to you. Testifying against a bill that would eliminate your exemption category is not counted.
• Discussions of broad social or economic problems that do not refer to specific legislation. Talking about the affordable-housing crisis in general terms is not lobbying; urging passage of a named bill to fix it is.
• Communications with members about legislation of direct interest to them, within limits, where the communication does not directly encourage lobbying by the members in certain ways. Member-communication rules are technical — get advice before relying on them heavily.
• Executive-branch and regulatory work that does not attempt to influence legislation. Advocating to an agency about how it writes or enforces a regulation is generally not 501(h) lobbying.
• Unreimbursed volunteer activity. If volunteers advocate on their own time with no payment or reimbursement from the charity, there is no expenditure and nothing counts against an electing charity's limits. This is one of the biggest practical advantages over the default test, where volunteer time can count.

Each exception has conditions and edge cases. Use the list as a planning checklist with your advisor, not as a DIY loophole finder.

How to Take the Election and Report Each Year​

Filing is deliberately easy:

1. Complete Form 5768 with your name, EIN, and address. An officer signs it.
2. Mail it to the IRS service center in the form instructions. There is no fee.
3. The election is effective for the tax year in which you file it and all later years until revoked. A mid-year filing covers the whole year, so file early in the year if you plan to lobby.
4. Revocation, if you ever want it, is also done on Form 5768.

Reporting afterward is easier than under the default test. Electing charities complete Form 990, Schedule C, Part II-A, which is essentially a worksheet: exempt purpose expenditures, lobbying nontaxable amount, grassroots nontaxable amount, actual direct and grassroots spending, and the four-year averaging table. Non-electing charities instead complete Part II-B, the narrative description with volunteer-hour detail.

Two compliance notes that trip up first-time filers:

• Affiliated groups are aggregated. If your charity is part of an affiliated group of organizations working on legislation together, the limits apply to the group as a whole with specific allocation rules. Do not assume each member gets its own $1 million cap.
• State lobbying registration is separate. The 501(h) election governs your federal tax status. Your state or city may still require you to register as a lobbyist, file activity reports, or observe gift bans once you cross its own thresholds — which are often much lower. Check both regimes before anyone visits the capitol.

What Happens If You Go Over​

A single-year overage is a tax bill, not a death sentence.

• If you exceed either the overall limit or the grassroots sublimit in a year, you owe a 25% excise tax on the excess under Section 4911(a), reported on Form 4720. Pay it, fix your budgeting, and move on.
• You lose exemption only if your lobbying normally exceeds 150% of the limits — the "lobbying ceiling amount" and "grassroots ceiling amount" — measured over the current year plus the prior three years (or fewer, in your first years of election). The overall ceiling tops out at $1.5 million.
• Organization managers who knowingly agree to excess expenditures can face a separate 5% tax under Section 4912, which underscores why the board should see the Schedule C numbers annually.

In other words, the system tolerates an accidental spike. It punishes a pattern of blowing past 150% year after year.

Common Mistakes That Waste the Election​

Treating the election as permission to do politics. The 501(h) election changes how lobbying is measured. It does nothing for campaign activity, which remains fully prohibited. Keep candidate work — including "nonpartisan" voter guides that favor one side — completely out of the charity.

Blowing the grassroots sublimit while watching only the total. Teams that run big public petitions and ad buys can breach the 25% grassroots cap while the overall budget looks fine. Code your chart of accounts with separate grassroots and direct lobbying categories before the campaign starts.

Counting the wrong base. Using total revenue or total expenses instead of exempt purpose expenditures overstates your limit. Fundraising and investment costs generally do not belong in the base. Reconcile the Schedule C worksheet to the 990, not to a back-of-the-envelope budget.

Forgetting the four-year average. A charity that spends 140% of its limit three years running may feel safe because no single year hit 150%. The averaging rule can still revoke exemption if the pattern continues. Review the four-year table at every board finance meeting in advocacy-heavy years.

Ignoring ballot measures. Direct democracy counts: spending to support or oppose a ballot initiative or referendum is generally lobbying under 501(h), split between direct and grassroots under specific rules. Budget initiative work inside your limits.

Mixing up volunteer value. Under the election, unreimbursed volunteer lobbying does not count — but reimbursed expenses, stipends, and staff time supporting those volunteers do. Track reimbursements carefully rather than assuming "volunteer-led" means "free for tax purposes."

Is the Election Right for Your Charity?​

For most small and midsize public charities that want to advocate at all, the answer is yes. The election costs nothing, the limits are generous relative to small budgets, the definitions are clearer, volunteer activity gets favorable treatment, and the reporting is simpler.

Consider staying under the default test only in narrow cases: you are ineligible (a church or private foundation), you spend heavily on grassroots work that would breach the 25% sublimit but might arguably be insubstantial under all the facts, or you are part of a complex affiliated structure where aggregation wipes out the benefit. Those are advisor conversations, not DIY decisions.

If you do elect, make it real operationally. Add lobbying and grassroots sub-accounts to your chart of accounts, require staff to code advocacy time weekly, save copies of communications that show whether a call to action was included, and reconcile the Schedule C four-year table before year-end so a November ad buy does not create a surprise excise tax in April.

Accurate bookkeeping from day one is what makes the bright line work. The election gives you the formula; your time-tracking and expense coding supply the inputs. Charities that track advocacy spending the way they track grants — contemporaneously, by category, with support attached — sail through 990 preparation and board questions. Those that reconstruct it months later do not.
