The Bureau of Internal Revenue (BIR) has formally presented to the Senate Blue Ribbon Committee a revamped tax audit framework designed to address long-standing taxpayer concerns and restore confidence in the country’s revenue enforcement system.
During the briefing, BIR Commissioner Charlito Martin R. Mendoza outlined the key reforms under Revenue Memorandum Order (RMO) No. 1-2026, describing them as a decisive shift toward a more predictable, transparent, and accountable audit regime.
Mendoza explained that the reforms were crafted through a technical working group formed to reassess existing audit policies and procedures. The Bureau also gathered input from private sector stakeholders, including recommendations submitted through the BIR Partnership with the Multisectoral Group (BIR-PMSG).
These consultations culminated in the lifting of the audit suspension on January 27 through Revenue Memorandum Circular No. 8-2026 and RMO No. 1-2026, jointly announced by the BIR and Finance Secretary Frederick Go.
At the core of the new framework is the Single-Instance Audit policy, which limits examinations to one Letter of Authority (LOA) per taxpayer per year. The measure aims to prevent overlapping or repetitive audits and reduce uncertainty for businesses and individual taxpayers.
The Bureau also introduced clearer definitions governing audit authority and strengthened controls over how examinations are initiated and conducted. Under the new system, case selection will be risk-based and system-assisted, minimizing discretion and promoting objective criteria in identifying audit targets. Assignments of revenue officers will now be anonymized to further safeguard impartiality.
In a move intended to streamline oversight and eliminate duplication, the BIR dissolved several special audit task forces, including the VAT Audit Section and the Large Taxpayers VAT Audit Unit. Their functions have been reintegrated into regular BIR offices to ensure uniform standards and centralized supervision.
Beyond structural adjustments, the reforms emphasize tighter discipline within the audit process. The Bureau committed to strengthening the review and approval of assessments and ensuring that audit findings meet established standards before final issuance.
Central to this effort is the expanded use of the “Revalida” or Audit-the-Auditor system, a quality control mechanism that evaluates the timeliness, accuracy, and propriety of audit work.
Mendoza underscored that the new audit policies form part of BIR DARES, the agency’s broader reform agenda. DARES stands for Digital and Data Transformation; Audit Reform and Accountability; Revenue Collection and Base Protection; Employee Empowerment and Welfare Promotion; and Service Excellence and Stakeholder Engagement.
He assured lawmakers that the reforms mark only the beginning of a sustained modernization effort.
“With these reforms, the BIR audit system is being strengthened. Standards are clear, and accountability is enforced,” Mendoza said. “We also recognize that reform is not static. The resumption of audits under this framework is part of a phased and continuing process. As implementation proceeds, we will keep listening, monitor outcomes, and refine our measures where necessary.”
The presentation signals the Bureau’s attempt to balance robust revenue enforcement with fairness and transparency—an effort closely watched by both lawmakers and the business community as audits resume under the new rules.
