PASAY CITY — The Bureau of Internal Revenue (BIR) briefed the Senate Blue Ribbon Committee today on a strengthened tax audit framework designed to address long-standing taxpayer concerns and instill a system that is fairer, more predictable, and transparent.
BIR Commissioner Charlito Martin Mendoza detailed the features of Revenue Memorandum Order (RMO) No. 1-2026, which marks the end of a recent audit suspension. Mendoza noted that the BIR formed a technical working group (TWG) to review and formulate reforms, collecting recommendations from the private sector through the BIR Partnership with the Multisectoral Group (BIR-PMSG). Following these consultations, the BIR and Department of Finance Secretary Frederick Go announced the lifting of the audit suspension on January 27.
The reforms presented to the Committee include clearer definitions of audit authority and the introduction of a “Single-Instance Audit Framework.” Under this rule, a taxpayer is generally subject to only one Electronic Letter of Authority (eLA) per taxable year, covering all applicable internal revenue taxes, including Value-Added Tax (VAT). This approach eliminates the administrative burden of simultaneous or fragmented audits.
The new system also utilizes risk-based and system-assisted selection, anonymized assignments, and the dissolution of special audit task forces. Functions previously held by the VAT Audit Section and the Large Taxpayers VAT Audit Unit have now been returned to regular BIR offices. To ensure these standards are upheld, the BIR is highlighting a “Revalida” or “Audit-the-Auditor” system. This mechanism serves as a continuing check on the quality, timeliness, and propriety of audit work while tightening the review and approval process of tax assessments.
For micro, small, and medium enterprises (MSMEs), the “Single-Instance” rule is a significant shift toward ease of doing business. Previously, a small business could face separate investigations for income tax and VAT at different times of the year. The new framework consolidates these into a single window, allowing owners to focus on operations rather than constant tax defense.
Furthermore, the shift to data-driven selection means that “honest” taxpayers with consistent reporting are less likely to be flagged. Selection is now based on objective criteria—such as unusual fluctuations in margins or third-party data mismatches—rather than the individual discretion of a revenue officer.
The BIR chief stressed that these measures are a core component of “BIR DARES,” the agency’s five-point priority reform and broader legacy agenda, which 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.
“With these reforms… the BIR audit system is being strengthened. Standards are clear, and accountability is enforced,” Mendoza assured the Committee. “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.”
