Black Lung Benefit Trusts - An Overview

Coal mine operators and workers in similar situations that are regularly exposed to harmful coal dust are at a high risk of suffering from Black Lung Disease.

IRC Section 501(c)(21) was added by the IRS under the Federal Black Lung Benefit Act of 1969. This requires companies to offer certain benefits to coal mine workers that are suffering from Black Lung Disease as a result of prolonged exposure to coal dust during their employment.

Organizations that operate for the purpose of serving those with Black Lung Disease are classified as Black Lung Benefit Trusts.


Are Black Lung Benefit Trusts Tax-Exempt?
