Title 26 › Subtitle D — Miscellaneous Excise Taxes › CHAPTER 42 — PRIVATE FOUNDATIONS; AND CERTAIN OTHER TAX-EXEMPT ORGANIZATIONS › Subchapter A — Private Foundations › § 4944
Private foundations must pay a tax when they make an investment that puts their charitable work at risk. The foundation pays 10% of the risky amount for each year (or part of a year) the investment stays risky. Any foundation manager who knowingly helped make that risky investment must also pay 10% per year (or part) of the amount, unless their involvement was not willful and was for a reasonable cause. If the investment is not fixed during the taxable period, the foundation must pay an extra 25% of the amount. If a manager refused to agree to fix the problem, that manager must pay an extra 5% of the amount. Investments whose main purpose is to carry out the foundation’s charitable work and not to make income are not treated as risky. If several managers are liable, each can be held responsible for the whole manager tax. For any one investment, the manager tax under the first rule cannot be more than $10,000, and the extra manager tax cannot be more than $20,000. "Taxable period" means the time from when the investment is made until the earliest of: the IRS mails a notice about the tax, the tax is assessed, or the investment is fixed. An investment is "fixed" when it is sold or disposed of and the proceeds are not put into another risky investment.
