What the label says
Section 6110 of the Internal Revenue Code makes IRS written determinations, such as private letter rulings, available for public inspection. Subsection (k)(3) attaches a limit: unless the Secretary otherwise establishes by regulations, a written determination may not be used or cited as precedent.
That is what “nonprecedential” means in Virtus. It is a statement about how the document may be used, taken from the statute and from the ruling’s own text. IRS Private Letter Ruling 202627005 states the same limit on page 5.
IRC § 6110(k)(3)

What it does not say
The label does not say a ruling is wrong, unreliable or worthless as a record. It shows how the IRS resolved one taxpayer’s request on the facts and representations that taxpayer submitted. That can be informative about how the agency approached a question.
It also does not tell you how far a ruling can support your own position. That is a professional judgment about your facts and the rules that apply to your situation, and it is not one Virtus makes for you.
Where Virtus shows it
The authority label travels with the source. It appears on the source record, in the cited-source view beside an answer, and in the document’s details, so it is still there when you open a citation, save a source or share a result.
An answer sentence that rests on a private letter ruling reports what the ruling says. It does not turn the ruling into a rule for other taxpayers.
Other kinds of source
The precedent limit attaches to written determinations. A Code section, a regulation and a revenue procedure are different kinds of authority with their own standing, and Virtus shows which kind you are reading. Tax Court opinions are planned and are not in the library today.
Questions to ask
- Do the facts represented in the request match the facts I am working with?
- What did the ruling actually conclude, and on which page?
- Is the source I am relying on the ruling itself or someone’s summary of it?
- What does the governing Code section or regulation say on its own?
The field guide walks through those questions on a real ruling, and the ruling itself is public.
