Commissioner of Internal Revenue vs. McDonald's Philippines Realty Corp.

The governing principle is that a separate or amended LOA must be issued in the name of a substitute or replacement revenue officer when the originally named officer is reassigned, transferred, or otherwise removed from handling the audit. Because the assessment was predicated on an examination conducted by an unauthorized officer, the Court ruled that the absence of a valid LOA violates due process and renders the assessment a nullity.

The Bureau of Internal Revenue issued LOA No. 00006717 on August 31, 2007, authorizing four specifically named revenue officers to examine the books of accounts of McDonald's Philippines Realty Corporation for all internal revenue taxes covering calendar year 2006. In December 2008, the BIR reassigned one of the original officers and designated a replacement officer, Rona Marcellano, to continue the audit through an internal referral memorandum. No new LOA was issued in Marcellano's name, nor was the original LOA amended to reflect the substitution. The audit proceeded, culminating in a 2011 Formal Letter of Demand and a 2013 Final Decision on Disputed Assessment for P16,229,506.83 in deficiency value-added tax.

• The BIR Large Taxpayers Service issued LOA No. 00006717 on August 31, 2007, naming revenue officers Eulema Demadura, Lover Loveres, Josa Gomez, and Emalyn dela Cruz to examine the respondent's books of accounts for calendar year 2006.
• On December 2, 2008, the BIR reassigned Demadura and issued Referral Memorandum No. 122-LOA-1208-00039, designating Rona Marcellano to continue the pending audit. The referral memorandum stated Marcellano would proceed pursuant to the original LOA, but no new LOA was issued in her name, and the original LOA was not amended.
• The audit concluded with the issuance of a Formal Letter of Demand dated January 11, 2011, assessing deficiency income tax and VAT. The respondent protested on February 23, 2011.
• The CIR issued a Final Decision on Disputed Assessment on April 18, 2013, canceling the income tax deficiency but upholding the P16,229,506.83 VAT deficiency.
• The respondent elevated the case to the CTA Division, which nullified the assessment on the ground that Marcellano lacked authority to conduct the audit. The CIR's motion for reconsideration was denied.
• The CIR appealed to the CTA En Banc, which affirmed the Division's ruling, finding that the absence of an LOA in the substitute officer's name violated due process and that the respondent was not estopped from questioning the lack of authority.

• The CIR maintained that an LOA is directed to the taxpayer rather than the revenue officer, permitting any revenue officer to act under a validly issued LOA during the audit period without requiring amendment.
• The CIR contended that Revenue Memorandum Order No. 43-90, which mandates a new LOA upon reassignment, was promulgated prior to the National Internal Revenue Code and is therefore obsolete and inapplicable.
• The CIR argued that even assuming RMO No. 43-90 remains effective, its provisions do not expressly stipulate that the absence of a new LOA automatically nullifies a tax assessment.
• The CIR distinguished Commissioner of Internal Revenue v. Sony Philippines, Inc. and Medicard Philippines, Inc. v. Commissioner of Internal Revenue, asserting they are inapplicable because no requirement exists to identify specific revenue officers within the LOA itself.
• The CIR asserted that the LOA remained effective at the time of the audit and that internal BIR General Audit Procedures do not govern the validity of the assessment.

• The respondent argued that Section 13 of the NIRC mandates that an LOA must specifically identify the revenue officer authorized to conduct the examination, requiring a new or amended LOA upon substitution.
• The respondent maintained that RMO No. 43-90 remains valid and consistent with the NIRC, as the latter did not repeal the LOA requirement but merely codified it.
• The respondent contended that conducting an audit without a valid LOA in the examining officer's name violates the taxpayer's constitutional right to due process, thereby invalidating the resulting assessment.
• The respondent emphasized that the referral memorandum is an internal administrative document that cannot substitute for the statutory LOA requirement under the NIRC.
• The respondent invoked Sony Philippines and Medicard as controlling precedents establishing that unauthorized examinations void subsequent assessments.

• Procedural Issues:
  • Whether the absence of a new or amended LOA for a substitute revenue officer renders the subsequent tax assessment void ab initio.
• Substantive Issues:
  • Whether reassigning a revenue officer originally named in an LOA and substituting them with a new officer without issuing a new or amended LOA violates the taxpayer's right to due process, usurps the statutory authority of the CIR or his duly authorized representatives, and contravenes BIR regulations.

• Procedural:
  • The Court affirmed the CTA's invalidation of the assessment. The audit conducted by the unauthorized officer was void for lack of jurisdiction, rendering the subsequent assessment a legal nullity. The referral memorandum did not cure the jurisdictional defect, and the taxpayer's failure to object earlier did not estop them from challenging the lack of authority.
• Substantive:
  • The Court held that due process requires identifying authorized officers in the LOA to allow taxpayers to verify the examiner's authority. Substituting officers via internal memoranda usurps the exclusive statutory power of the CIR or duly authorized representatives under Sections 6, 10(c), and 13 of the NIRC. The Court found RMO No. 43-90 remains fully effective and explicitly requires a new LOA upon reassignment, concluding that the practice of rotating officers without amended LOAs violates tax audit regulations and must be discontinued.

• Due Process in Tax Audits — Requires taxpayers to verify the legal authority of examining officers through a valid LOA that expressly names them. The Court applied this doctrine to establish that the absence of a properly issued LOA for the substitute officer deprived the respondent of the opportunity to verify authority, thereby rendering the audit and assessment constitutionally infirm and void.
• Exclusive Statutory Authority for Tax Examination — Establishes that only the Commissioner of Internal Revenue or his duly authorized representatives may grant examination authority via an LOA under the NIRC. The Court applied this principle to rule that internal referral memoranda issued by subordinate officials cannot supplant or delegate this exclusive statutory power, and any examination conducted without proper LOA authorization is a nullity.

• "The issuance of an LOA prior to examination and assessment is a requirement of due process. It is not a mere formality or technicality." — The Court invoked this principle to reject the petitioner's characterization of the LOA as a mere administrative formality, emphasizing that its absence directly violates the taxpayer's constitutional right to be informed of the examining officer's lawful authority.
• "Due process requires that taxpayers must have the right to know that the revenue officers are duly authorized to conduct the examination and assessment, and this requires that the LOAs must contain the names of the authorized revenue officers." — The Court relied on this formulation to establish the jurisdictional requirement that an LOA must explicitly link the grant of authority to the specific officers conducting the audit, ensuring taxpayer verification and preventing unauthorized examinations.
• "In the absence of such an authority, the assessment or examination is a nullity." — The Court applied this settled rule to conclude that Marcellano's audit, conducted without a new or amended LOA, lacked legal foundation, thereby invalidating the P16.2M VAT deficiency assessment in its entirety.

• Commissioner of Internal Revenue v. Sony Philippines, Inc. — Cited as controlling precedent for the rule that an LOA must specifically authorize a revenue officer to examine a taxpayer’s books; the Court followed its holding that an assessment predicated on an unauthorized examination is void.
• Medicard Philippines, Inc. v. Commissioner of Internal Revenue — Followed to reinforce that due process demands a properly secured LOA before proceeding with examination and assessment, and that a Letter Notice alone cannot substitute for the statutory LOA requirement.

• Section 6(A), National Internal Revenue Code (NIRC) — Grants the Commissioner or his duly authorized representative the exclusive power to authorize the examination of any taxpayer and the assessment of the correct amount of tax.
• Section 10(c), NIRC — Empowers Revenue Regional Directors, under CIR supervision, to issue Letters of Authority for the examination of taxpayers within their respective jurisdictions.
• Section 13, NIRC — Mandates that a Revenue Officer assigned to perform assessment functions may only examine taxpayers and recommend deficiency assessments pursuant to a valid LOA issued by the Revenue Regional Director.
• Section 291, NIRC — Provides for the repeal of inconsistent laws and regulations; the Court applied this provision to determine that RMO No. 43-90 was not repealed by the NIRC because its provisions remain consistent with the Code's statutory framework.
• Revenue Memorandum Order No. 43-90, Section D(5) — Explicitly requires the issuance of a new LOA upon the reassignment or transfer of cases to another revenue officer, serving as the direct regulatory basis for the Court's ruling against the substitution practice.
