Trust fund recovery penalty. If communications, air transportation, and indoor tanning services taxes are collected but not paid to the U.S. Treasury or are willfully not collected, the trust fund recovery penalty may apply. The penalty is the full amount of the unpaid tax.

The trust fund recovery penalty may be imposed on all persons who are determined by the IRS to be responsible for collecting, accounting for, and paying over these taxes, and who acted willfully in not doing so.

A responsible person can be an officer or employee of a corporation, a partner or employee of a partnership, an employee of a sole proprietorship, an accountant, or a volunteer director/trustee. A responsible person may also include one who signs checks for the business or otherwise has authority to cause the spending of business funds.

“Willfully” means voluntarily, consciously, and intentionally. A responsible person acts willfully if they know the required actions aren't taking place.
