Day 1. preserve and verify
A BIR letter of authority authorizes examination within its stated scope. Receiving one is not itself a final assessment of tax due. Keep the document, envelope or service evidence and date received.
BIR introduced the REVIE LOA Verifier in RMC 5-2026. Use the official channel to check authenticity. Avoid sending sensitive records to an unverified contact.
Days 2 and 3. clarify the scope
Identify the taxpayer, taxable period, authorized officers and covered taxes. Ask your adviser to check the document and related requests. The 2026 audit reforms include a general single-instance framework, with exceptions. Do not apply an old multiple-LOA assumption without checking the current rules.
The “first seven days” is a planning aid, not a universal statutory response deadline. Follow the actual notice and applicable requirements.
Days 4 and 5. build the working file
Gather returns, filing and payment confirmations, ledgers, invoices and relevant reconciliations. Keep an index that connects each request to the supporting file. Assign one response owner.
Preserve original records. Do not alter documents to make them appear compliant. Mark working explanations separately from source evidence.
Days 6 and 7. review the response plan
Review gaps with the accountant or counsel. Record questions, responsible people and deadlines. Make a log of what was submitted and when. A quick unreviewed response can create more confusion than it resolves.
