Title 26 › Subtitle Subtitle D— Miscellaneous Excise Taxes › Chapter 42— PRIVATE FOUNDATIONS; AND CERTAIN OTHER TAX-EXEMPT ORGANIZATIONS › Subchapter B— Black Lung Benefit Trusts › § 4953
If a person contributes more to a black lung benefit trust than the deduction allowed for the year, the person owes an excise tax equal to 5 percent of the excess contribution. The excess carries forward: last year's excess stays in the count until it is soaked up by later years' unused deduction room or paid back by the trust. The trust can return excess amounts to the contributor without penalty — distributions up to the excess contribution do not count as self-dealing, as taxable expenditures, or as acts contrary to the trust's tax-exempt purpose.
