What stays true

Rely on it, then check it.

The source keeps its own form, the answer keeps to what the library holds, and the work keeps its trail.

The original stays the original.

Virtus keeps the publisher’s document distinct from the text it searches, and marks the quoted passage where the publisher put it.

When the library has no support, it says so.

A ruling binds only the taxpayer who asked for it, and a library has edges. When nothing it holds supports the question, the answer is “no cited answer” rather than a guess.

Section 1361(a)(1) provides that the term “S corporation” means, with respect to any taxable year, a small business corporation for which an election under § 1362(a) is in effect for the taxable year.

Carry the trail with the work.

Mark the passage you rely on in one of four colours and download a working copy with standard PDF annotations. The original stays as the publisher issued it, and the conversation stays with its sources in a private project.
