26 U.S. Code § 651 - Deduction for trusts distributing current income only
If the amount of income required to be distributed currently exceeds the distributable net income of the trust for the taxable year, the deduction shall be limited to the amount of the distributable net income. For this purpose, the computation of distributable net income shall not include items of income which are not included in the gross income of the trust and the deductions allocable thereto.
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.
