26 U.S. Code § 6404 - Abatements
No claim for abatement shall be filed by a taxpayer in respect of any assessment of any tax imposed under subtitle A or B.
The Secretary is authorized to abate the unpaid portion of the assessment of any tax, or any liability in respect thereof, if the Secretary determines under uniform rules prescribed by the Secretary that the administration and collection costs involved would not warrant collection of the amount due.
In the case of an assessment of any tax imposed by chapter 1 attributable in whole or in part to a mathematical error described in section 6213(g)(2)(A), if the return was prepared by an officer or employee of the Internal Revenue Service acting in his official capacity to provide assistance to taxpayers in the preparation of income tax returns, the Secretary is authorized to abate the assessment of all or any part of any interest on such deficiency for any period ending on or before the 30th day following the date of notice and demand by the Secretary for payment of the deficiency.
The Secretary shall abate any portion of any penalty or addition to tax attributable to erroneous advice furnished to the taxpayer in writing by an officer or employee of the Internal Revenue Service, acting in such officer’s or employee’s official capacity.
This paragraph shall be applied separately with respect to each item or adjustment.
Rules similar to the rules of section 6213 shall apply for purposes of determining the date of the mailing referred to in paragraph (1).
Rules similar to the rules of section 6512(b) shall apply for purposes of this subsection.
For authority to suspend running of interest, etc. by reason of Presidentially declared disaster or terroristic or military action, see section 7508A.

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.
