Title 26 › Subtitle D — Miscellaneous Excise Taxes › CHAPTER 41 — PUBLIC CHARITIES › § 4911
A 25% tax must be paid on an organization’s “excess lobbying expenditures” if the organization has made a 501(h) election for the year. “Excess lobbying expenditures” means whichever is larger: the amount by which the group’s total lobbying spending goes over its allowed non-taxable lobbying amount, or the amount by which its grassroots spending goes over its allowed non-taxable grassroots amount. “Lobbying” means spending to try to shape laws by swaying the public or by contacting lawmakers or officials; “grassroots” means efforts to influence the public (a narrower definition of lobbying for these rules). The allowed non-taxable lobbying amount is the smaller of $1,000,000 or a number based on the group’s exempt purpose spending (money used for charitable, religious, educational, etc., work). If exempt spending is up to $500,000, the allowed amount is 20% of that spending. If it is over $500,000 but not over $1,000,000, the allowed amount 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 non-taxable grassroots amount is 25% of that lobbying amount. Exempt purpose spending includes normal program and admin costs (and even lobbying amounts), but not payments mainly for fundraising. Some activities are not treated as lobbying, such as nonpartisan research, technical advice given in response to a written government request, certain member communications, and routine communications with officials unless the main goal is to influence legislation. When related charities are “affiliated,” they are often treated as one group for these limits and for allocating any excess tax. Depreciation rules apply and must use straight-line accounting.
