BIR Resumes Tax Audits in 2026: What Philippine Businesses Need to Know

Published on January 28, 2026

The Bureau of Internal Revenue (BIR) has officially resumed tax audits and field operations following the issuance of Revenue Memorandum Circular (RMC) No. 8-2026 on January 27, 2026.

The circular lifts the earlier suspension of audit activities, allowing the issuance of audit authorizations and the continuation of enforcement operations nationwide. For Philippine businesses, this means compliance examinations may now proceed again under updated operational guidelines.

Understanding what this development means can help businesses prepare and respond properly if selected for audit.

Why Were Tax Audits Previously Suspended?

In 2025, the BIR temporarily suspended audit and related field operations through the issuance of Revenue Memorandum Circular (RMC) No. 107-2025.

The suspension covered the issuance of Letters of Authority (LoAs), Mission Orders, and other audit actions to allow the agency to review existing audit procedures and address concerns related to enforcement practices.

This temporary measure was intended to strengthen safeguards, improve transparency, and refine internal controls before audit and field operations were resumed under updated guidelines.

What Does RMC No. 8-2026 Allow?

With the issuance of RMC No. 8-2026, the BIR is now authorized to:

Resume audit and field operations
Issue electronic Letters Authority (eLAs) and Mission Orders
Continue and complete audit cases previously affected by the suspension
Conduct enforcement activities related to tax compliance

The circular effectively restores audit operations nationwide, enabling revenue officers to continue examinations necessary for tax enforcement. Detailed audit procedures moving forward are governed by accompanying operational issuances, which guide how audits will be conducted under the resumed framework.

Revenue Impact of Audit Resumption

Audit enforcement activities contribute a portion of overall tax collections each year. Government reports indicate that resumed audit operations are expected to help the BIR move closer to its 2026 revenue collection target of ₱3.58 trillion, with enforcement activities contributing a meaningful share of collections.

Officials previously noted that the temporary suspension of audits affected revenue performance in 2025, prompting the restoration of enforcement operations under improved safeguards.

What This Means for Philippine Businesses

With audits now resumed, businesses may again be subject to compliance examinations. Companies are encouraged to review their records and ensure documentation is ready in case audit authorities request information.

Recommended preparation steps include:

Ensuring accounting records and tax filings are complete and updated
Organizing financial documents for easy retrieval
Verifying audit authorizations before responding to requests

Taxpayers receiving a Letter of Authority may confirm its validity using official BIR verification tools. Resources such as this BIR LOA Verifier guide can help businesses understand how to verify audit authorizations properly before submitting records.

Maintaining accurate records helps reduce operational disruption during audit processes.
