CASE DIGEST : Republic of the Philippines v. Robiegie Corporation G.R. No. 260261, October 3, 2022 GAERLAN

FACTS

The Bureau of Internal Revenue (BIR) issued Letter of Authority (LOA) No. 00037842 authorizing Revenue Officer (RO) Jose Francisco David, Jr. to examine the books of accounts of Robiegie Corporation for taxable year 2008 pursuant to the investigatory powers of the Commissioner of Internal Revenue (CIR) under Sections 6(A) and 13 of the National Internal Revenue Code (NIRC). Before the audit was completed, the investigation was reassigned to another revenue officer, RO Cecille Dy, through a Memorandum Referral rather than through a new or amended LOA. Based on RO Dy's investigation, the BIR issued a Preliminary Assessment Notice (PAN), followed by a Formal Letter of Demand (FLD) and Final Assessment Notices (FANs) assessing Robiegie deficiency income tax, VAT, and expanded withholding tax amounting to more than ₱10.8 million.

After the BIR failed to collect the assessed taxes administratively, it filed a collection case before the Court of Tax Appeals (CTA). The CTA Division and later the CTA En Banc dismissed the complaint, holding that the assessments were void because RO Dy was never authorized through a valid LOA to conduct the investigation. The Republic, through the CIR, argued before the Supreme Court that the reassignment by Memorandum Referral was sufficient, invoking the CIR's authority to reassign revenue officers and emphasizing the "one LOA per taxable year" rule.

ISSUE

Whether the reassignment of a taxpayer's investigation from one revenue officer to another through a Memorandum Referral, without the issuance of a new or amended Letter of Authority (LOA), is valid under Sections 6(A) and 13 of the National Internal Revenue Code, thereby making the resulting tax assessments enforceable.

Whether the deficiency tax assessments and the subsequent collection case may be sustained despite the absence of a valid LOA specifically authorizing the revenue officers who actually conducted the audit and issued the assessments against the taxpayer.

HELD

The Supreme Court denied the petition and affirmed the CTA, ruling that the tax assessments were null and void. The Court held that under Sections 6(A) and 13 of the National Internal Revenue Code, the power to examine a taxpayer's books originates solely from a validly issued Letter of Authority (LOA), which serves as the formal delegation by the CIR of the authority to conduct a tax investigation. Consequently, when the original revenue officer is reassigned, retires, or can no longer continue the audit, the substitute revenue officer must be issued a new or amended LOA before exercising investigatory powers. A Memorandum Referral merely reassigning the case cannot substitute for the statutory requirement of an LOA because it does not validly delegate the CIR's investigatory authority.

The Court likewise clarified that the "one LOA per taxpayer per taxable year" rule under Revenue Memorandum Order (RMO) No. 8-2006 does not prohibit the issuance of a new LOA when a reassignment becomes necessary. Rather, the original LOA is deemed cancelled and replaced by the new LOA issued to the newly assigned revenue officer. Citing its earlier rulings, particularly Medicard Philippines, Inc. v. Commissioner of Internal Revenue, the Court emphasized that compliance with the LOA requirement is an essential aspect of due process in tax investigations. Since the assessments against Robiegie were based on an audit conducted by officers who lacked a valid LOA, the assessments had no legal basis and could not support the government's action for collection of deficiency taxes. Accordingly, the Republic's petition was denied.
