There's a persistent myth in the nonprofit world that 501(c)(3) organizations have to stay quiet on public issues or risk losing their tax exemption. It scares good organizations into silence at exactly the moments their communities need a voice. The truth is more useful: your nonprofit can advocate, it can lobby within generous limits, and it can help people participate in democracy. What it absolutely cannot do is take sides in an election between candidates. Learn where that line sits, and you can be far bolder than you probably are today.
Let's walk through it the way a board member should understand it: what's flat-out prohibited, what's permitted and how much, and what most nonprofits could be doing but aren't.
The One Bright Line: No Partisan Campaign Activity
Here's the rule that has no exceptions. A 501(c)(3) may never support or oppose a candidate for public office. This comes from the Johnson Amendment, and it's absolute. No endorsements. No "we're backing this candidate." No contributions of money or staff time to a campaign. No rating or ranking candidates on your issues. No letting one candidate use your facilities on terms you wouldn't offer another.
And it's broader than most people expect. "Appears to support or oppose" is enough to cross the line, even for a nonpartisan office. If a reasonable person watching would think your organization is favoring someone, you've got a problem, whether or not you said the magic words. A candidate showing up at your event and being allowed to work the room is a risk. A biased "voter guide" that just happens to make one candidate look good is a violation.
The reason this ban is so strict is that it protects you. Nonpartisanship is exactly what lets a nonprofit keep credibility across the political spectrum, keep diverse funders, and stay focused on mission instead of getting torn apart by internal political fights. If you genuinely want to do partisan work, that's what a separate 501(c)(4) is for, and donors to it don't get a tax deduction. Never run that activity through your (c)(3).
Candidate versus issue is the whole game. Anything about a candidate is off-limits. Almost anything about an issue is fair territory.
Lobbying Is Allowed, and You Have More Room Than You Think
Now the part that surprises people. Lobbying, meaning trying to influence specific legislation, is completely legal for a public charity. You're just limited in how much of it you do. There are two ways that limit gets measured, and one of them is far better than the other.
The default is the vague "no substantial part" test: no substantial part of your activities may go to lobbying. The problem is that nobody, not Congress, not the IRS, has defined "substantial." It looks at your overall activities, not dollars, and leaves you guessing.
The better option for most organizations is to make the 501(h) election by filing IRS Form 5768. It takes under five minutes and swaps that fuzzy standard for clear, objective dollar limits. Under 501(h), you can spend up to 20% of the first $500,000 of your exempt-purpose expenditures on lobbying (the percentage slides down as budgets grow, with a hard cap of $1 million a year). Of that lobbying budget, up to a quarter can go to grassroots lobbying, which means asking the public to contact legislators. Go over the limit and you owe an excise tax, not the loss of your exemption. The bright certainty alone is worth the five minutes for any organization that lobbies with any regularity.
A quick concrete case. Say your food-bank coalition wants to email your legislator urging a "yes" on a specific hunger-relief bill (that's direct lobbying, because it names a bill and states a view), and also asks your newsletter readers to call their representatives about it (that's grassroots lobbying). Under 501(h) that's not just legal, it's measurable. You track the spending, keep direct and grassroots separate, and you know exactly where you stand.
What You Can Do Freely (No Lobbying Limit at All)
Plenty of the advocacy you care about doesn't even count against your lobbying cap:
- Issue advocacy. You can champion your cause all day long, and you don't have to go silent during election season. You only have to keep it about the issue and never tie it to a candidate.
- Nonpartisan analysis, education, and research on a policy question.
- Technical advice to a legislative committee that asks for it in writing.
- Self-defense lobbying on legislation affecting your organization's own existence or powers.
- Ballot-measure work, which is a special and often-misunderstood case, covered next.
Ballot Measures Are Lobbying, Not Elections
This one trips up experienced people. A ballot measure, an initiative, a referendum, a bond issue, is a vote on a law, not a candidate. So supporting or opposing it counts as lobbying, not prohibited campaign activity. That means your nonprofit generally can collect signatures to qualify a measure, take a public position for or against it, organize volunteers, and host educational forums, all within your normal lobbying limits.
Two cautions. First, it's still lobbying, so it still counts against your 501(h) budget; it isn't a free-for-all. Second, if you devote substantial funds to a measure, some states require you to file a campaign-finance expenditure report. Check with your state's campaign-finance office before you go big.
You can also help people vote, as long as you stay strictly nonpartisan: register voters, share where and when and how to cast a ballot, remind people to turn out, and host candidate forums where every candidate for an office gets an equal invitation and equal time. Just never pick sides.
The Board's Job Here
You don't need to memorize the percentages. You do need to make sure your organization knows the bright line, has probably made the 501(h) election if it lobbies at all, and isn't scaring itself into silence over activities that are perfectly legal. When something touches candidates or an election, that's the moment to slow down and, where real money or visibility is involved, get a quick read from counsel. The specifics of your state's election and campaign-finance rules vary, and a five-minute check beats an audit.
So take the fear off the table. Your organization is allowed to have a voice, allowed to move legislation, allowed to help its community show up on Election Day. The only thing it can't do is play favorites between candidates. Draw that one line clearly, and everything on the permitted side of it becomes a tool you're finally free to use.
