G.R. No. 260261 . October 03, 2022
REPUBLIC OF THE PHILIPPINES, PETITIONER, VS. ROBIEGIE CORPORATION, RESPONDENT.

FACTS

The Bureau of Internal Revenue (BIR) issued Letter of Authority (LOA) No. 00037842 on July 27, 2009, authorizing Revenue Officer (RO) Jose Francisco David, Jr. to examine the books of Robiegie Corporation for taxable year 2008. Subsequently, a Memorandum Referral reassigned the investigation to RO Cecille D. Dy. Following an investigation conducted by RO Dy, the BIR issued a Formal Letter of Demand assessing Robiegie with deficiency taxes totaling over P10.8 million for 2008. After failing to collect, the Republic filed a collection case before the Court of Tax Appeals (CTA).
Robiegie contested the assessment, arguing it was void due to RO Dy’s lack of authority. The Republic maintained the reassignment was valid under BIR administrative issuances, arguing that RO Dy derived her authority from the original LOA. The CTA Second Division dismissed the complaint, ruling the assessment was null because RO Dy was not authorized by a valid LOA. The CTA En Banc affirmed this decision, prompting the Republic to elevate the case to the Supreme Court via a petition for review on certiorari.

ISSUE

Whether the reassignment of a tax investigation from one revenue officer to another, effected through a memorandum referral instead of a new or amended Letter of Authority, confers valid authority to conduct the examination and issue a consequent assessment.

RULING

The Supreme Court denied the petition and affirmed the CTA En Banc‘s decision. The legal logic centers on the statutory distinction between the Commissioner of Internal Revenue’s (CIR) general administrative power to reassign personnel and the specific, delegated power to authorize a tax examination. The Court held that the power to examine a taxpayer and assess taxes is a specific delegation of authority under Sections 6(A) and 13 of the National Internal Revenue Code (NIRC), which expressly requires a Letter of Authority (LOA) issued by authorized officials like the Revenue Regional Director. This LOA is the official document that empowers a particular revenue officer to conduct an examination.
While the CIR has the general power under Section 17 of the NIRC to reorganize and reassign BIR personnel for administrative efficiency, this power is separate and cannot override the specific statutory requirement for an LOA to validate a tax investigation. The reassignment memorandum in this case, issued only by a Revenue District Officer not authorized to issue LOAs, was insufficient to confer the investigative authority mandated by law. Consequently, the investigation conducted by RO Dy and the resulting assessment were performed without legal authority and are void. The Court emphasized that administrative issuances cited by the Republic cannot amend the clear provisions of the NIRC, and the ruling in Commissioner of Internal Revenue v. Sony Philippines, Inc. remains controlling: the authority to examine must be grounded in a valid LOA.
