26 U.S. Code § 7521 - Procedures involving taxpayer interviews
Any officer or employee of the Internal Revenue Service in connection with any in-person interview with any taxpayer relating to the determination or collection of any tax shall, upon advance request of such taxpayer, allow the taxpayer to make an audio recording of such interview at the taxpayer’s own expense and with the taxpayer’s own equipment.
If the taxpayer clearly states to an officer or employee of the Internal Revenue Service at any time during any interview (other than an interview initiated by an administrative summons issued under subchapter A of chapter 78) that the taxpayer wishes to consult with an attorney, certified public accountant, enrolled agent, enrolled actuary, or any other person permitted to represent the taxpayer before the Internal Revenue Service, such officer or employee shall suspend such interview regardless of whether the taxpayer may have answered one or more questions.
Any attorney, certified public accountant, enrolled agent, enrolled actuary, or any other person permitted to represent the taxpayer before the Internal Revenue Service who is not disbarred or suspended from practice before the Internal Revenue Service and who has a written power of attorney executed by the taxpayer may be authorized by such taxpayer to represent the taxpayer in any interview described in subsection (a). An officer or employee of the Internal Revenue Service may not require a taxpayer to accompany the representative in the absence of an administrative summons issued to the taxpayer under subchapter A of chapter 78. Such an officer or employee, with the consent of the immediate supervisor of such officer or employee, may notify the taxpayer directly that such officer or employee believes such representative is responsible for unreasonable delay or hindrance of an Internal Revenue Service examination or investigation of the taxpayer.
This section shall not apply to criminal investigations or investigations relating to the integrity of any officer or employee of the Internal Revenue Service.
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.
