26 U.S. Code § 6671 - Rules for application of assessable penalties
The penalties and liabilities provided by this subchapter shall be paid upon notice and demand by the Secretary, and shall be assessed and collected in the same manner as taxes. Except as otherwise provided, any reference in this title to “tax” imposed by this title shall be deemed also to refer to the penalties and liabilities provided by this subchapter.
The term “person”, as used in this subchapter, includes an officer or employee of a corporation, or a member or employee of a partnership, who as such officer, employee, or member is under a duty to perform the act in respect of which the violation occurs.
Written determinations for this section
These documents, sometimes referred to as "Private Letter Rulings", are taken from the IRS Written Determinations page; the IRS also publishes a fuller explanation of what they are and what they mean. The collection is updated (at our end) daily. It appears that the IRS updates their listing every Friday.
Note that the IRS often titles documents in a very plain-vanilla, duplicative way. Do not assume that identically-titled documents are the same, or that a later document supersedes another with the same title. That is unlikely to be the case.
Release dates appear exactly as we get them from the IRS. Some are clearly wrong, but we have made no attempt to correct them, as we have no way guess correctly in all cases, and do not wish to add to the confusion.
We truncate results at 20000 items. After that, you're on your own.
