Why You Need to Act Now

A Letter of Authority is not just a letter — it is the start of a formal BIR audit. Here is what is at stake.

Your Deadline Is Already Running

From the moment you receive a Letter of Authority, you have a limited reglementary period to respond. Every day you wait is a day closer to losing your right to present your side.

Silence Means the BIR Decides for You

If you don't respond, the BIR will assess your tax liability based on their best available evidence — not yours. You lose the chance to present records, explain discrepancies, or contest findings.

Penalties Compound Quickly

A 25% surcharge applies for late compliance. If the BIR determines willful neglect, that jumps to 50% — plus interest at the rate prescribed by law. What starts as a manageable audit can become an unmanageable debt.

Early Response Protects Your Rights

Filing a timely acknowledgment letter establishes your cooperative stance and preserves your right to contest any assessment. It's the single most important step in a BIR audit.

What Most Taxpayers Get Wrong

These are the most common mistakes we see — and each one can cost you thousands in unnecessary penalties.

Submitting all records immediately without strategy

Handing over everything at once gives the BIR examiner full control of the narrative. A strategic, phased response protects your position.

Not checking if the LOA is valid

An LOA must be signed by the correct BIR officials, specify the correct taxable year, and match the authorized scope. Invalid LOAs can be challenged.

Ignoring it and hoping it goes away

The BIR does not forget. Ignoring an LOA leads to assessment based on best available evidence — with surcharges and interest — and you lose the right to protest.

Confusing an LOA with other BIR notices

An LOA, Subpoena Duces Tecum, and assessment notices each have different deadlines and require different responses. Using the wrong approach can waive your rights.
