Title 26 › Subtitle Subtitle D— - Miscellaneous Excise Taxes › Chapter CHAPTER 41— - PUBLIC CHARITIES › § 4911
A 25% tax must be paid on an organization’s excess lobbying spending for a tax year if the organization has made a 501(h) election. “Excess lobbying spending” is the larger of (1) money spent to influence legislation that goes over the organization’s allowed lobbying amount for the year, or (2) grassroots spending that goes over the allowed grassroots amount. The allowed lobbying amount is the smaller of $1,000,000 or an amount based on the organization’s exempt purpose spending: if exempt spending is not over $500,000, the allowed amount is 20% of that spending; if over $500,000 but not over $1,000,000, it is $100,000 plus 15% of the excess over $500,000; if over $1,000,000 but not over $1,500,000, it is $175,000 plus 10% of the excess over $1,000,000; if over $1,500,000, it is $225,000 plus 5% of the excess over $1,500,000. The allowed grassroots amount is 25% of the allowed lobbying amount. Short definitions: “lobbying expenditures” are money spent to influence legislation; “grassroots expenditures” are money spent to influence the public about legislation; “influencing legislation” means trying to affect public opinion or communicating with lawmakers or officials who help make laws. Exceptions include sharing nonpartisan research, giving technical advice when a government body asks in writing, speaking to a legislative body about actions that would affect the organization’s existence or tax status, ordinary communications with bona fide members about issues that directly affect them (with special rules when members are asked to contact others or lawmakers), and some communications with government officials that are not mainly meant to influence legislation. “Exempt purpose expenditures” are amounts spent for charitable, religious, educational, or similar purposes (including some admin and even some lobbying costs), but do not include amounts mainly for fundraising. Capital costs are treated separately and depreciation must be straight-line. If two or more 501(c)(3) organizations are affiliated and at least one has the 501(h) election, the rules treat the group as one for limits and tax, with each elected group member responsible for its share.
