A private letter ruling, or PLR, is a written statement issued to a taxpayer that interprets and applies tax laws to the taxpayer's represented set of facts. A PLR is issued in response to a written request submitted by a taxpayer. A PLR may not be relied on as precedent by other taxpayers or by IRS personnel. It is important to distinguish between a PLR, generally issued by Chief Counsel, and TEB's Voluntary Closing Agreement Program . A PLR is appropriate when the issuer/taxpayer wishes to confirm with the IRS that a prospective transaction will not likely result in a tax violation. Whereas, a closing agreement is appropriate when the issuer/taxpayer wants to conclusively resolve tax matters relating to a violation, even if there are legal arguments that can be asserted to suggest a violation did not in fact occur
