According to CIR v. Metro Star Superama, Inc. (2010), why is the issuance of a Preliminary Assessment Notice (PAN) essential before collecting deficiency taxes?

• A. It allows immediate collection without further notice.
• B. It serves as the first formal step but is optional.
• C. It informs the taxpayer of liability with facts and the law, protecting due process.
• D. It eliminates the need for a LOA.

Answer: (C)

The essential idea is that collecting deficiency taxes must follow a process that protects the taxpayer’s right to know what is being claimed and why. A Preliminary Assessment Notice serves as that critical step by spelling out the taxpayer’s liability along with the facts and the law that support it. This gives the taxpayer clear notice of the deficiency and the basis for it, enabling a response, defense, or appeal before any collection actions take place. That is why it is considered essential before collection.

If you’re weighing the other possibilities, they don’t fit because immediate collection without notice isn’t allowed—the PAN is the notice itself. It isn’t optional—the law requires this step before proceeding with collection. And it doesn’t replace other procedures like a LOA; the PAN and LOA serve different purposes in the assessment and collection framework.
