BIR to roll out data-driven tax audits under stricter Letter of Authority rules

Finance Secretary Frederick Go announces a shift to AI-powered, risk-based tax modeling to eliminate arbitrary audits and “fake” LoAs.

Tax audits may soon become more predictable, and for many Filipino businesses, that alone would be a major shift.

The Bureau of Internal Revenue (BIR) is moving toward a digitized, data-driven system for issuing Letters of Authority (LoA), an overhaul meant to rein in repeated and arbitrary audits.

For years, audits have meant uncertainty, disruption, and lost income, especially for firms already stretched by high costs and tight margins. Multiple LoAs in a single year became common, forcing businesses to treat compliance as a defensive exercise rather than a routine obligation.

LOA reform pushes for quality reform

The shift was outlined by Finance Secretary Frederick Go in a briefing before the Financial Executives Institute of the Philippines. He said audit selection will rely on automated, risk-based modeling, with fewer BIR units allowed to issue LoAs and tighter limits on how often a taxpayer can be audited.

“The keyword here is quality assessments, and we will not allow arbitrary or abusive audits. Most importantly, when we resume this activity, we will reduce the number of departments within the BIR authorized to issue letters of authority, and reduce the number of letters of authority a taxpayer can receive in any given year,” Go said.

Countering systemic abuse and “fake” audits

The reset follows the suspension of LoAs in November last year after allegations that the system was abused to harass taxpayers. Reports surfaced of fake or unauthorized LoAs being used to extort money or overlap audits, effectively doubling tax payments for some affected businesses.

The BIR has said LoAs will return within the first quarter of 2026 as it works toward its revised ₱3.431-trillion revenue target, this time under stricter controls.

A welcome change that aims to restore confidence

The Federation of Philippine Industries (FPI) welcomed the move, saying it could restore confidence. If applied properly, it could ease pressure on businesses and free up time and capital for growth. If not, it risks becoming another reform that sounds strong but feels familiar on the ground.

FPI chairperson Elizabeth Lee said the group hopes the new process will address concerns within the business community about audits being arbitrary.

“For decades, taxpayers dreaded the Letter of Authority—a document that could arrive multiple times a year, often leading to harassment and confusion,” Lee said. “The new roadmap promises a different approach: audits chosen by data, not discretion. Artificial intelligence will flag risks, ICT systems will be upgraded, and taxpayer portals will be modernized. By 2028, the BIR envisions a system where compliance is predictable, transparent, and far less prone to abuse.”
