26 U.S. Code § 441 - Period for computation of taxable income
Taxable income shall be computed on the basis of the taxpayer’s taxable year.
For purposes of this subtitle, the term “annual accounting period” means the annual period on the basis of which the taxpayer regularly computes his income in keeping his books.
For purposes of this subtitle, the term “calendar year” means a period of 12 months ending on December 31.
For purposes of this subtitle, the term “fiscal year” means a period of 12 months ending on the last day of any month other than December. In the case of any taxpayer who has made the election provided by subsection (f) the term means the annual period (varying from 52 to 53 weeks) so elected.
The Secretary may by regulation provide terms and conditions for the application of this subsection to a partnership, S corporation, or personal service corporation (within the meaning of section 441(i)(2)).
For purposes of this subtitle, the taxable year of any DISC shall be the taxable year of that shareholder (or group of shareholders with the same 12-month taxable year) who has the highest percentage of voting power.
If 2 or more shareholders (or groups) have the highest percentage of voting power under paragraph (1), the taxable year of the DISC shall be the same 12-month period as that of any such shareholder (or group).
The Secretary shall prescribe regulations under which paragraphs (1) and (2) shall apply to a change of ownership of a corporation after the taxable year of the corporation has been determined under paragraph (1) or (2) only if such change is a substantial change of ownership.
For purposes of this subtitle, the taxable year of any personal service corporation shall be the calendar year unless the corporation establishes, to the satisfaction of the Secretary, a business purpose for having a different period for its taxable year. For purposes of this paragraph, any deferral of income to shareholders shall not be treated as a business purpose.

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.
