This is the receipt-to-production response workflow after a BIR LOA or eLA arrives. For the short definition, see What is a BIR Letter of Authority? For the scope of legal assistance, see BIR Audit Defense.
Direct answer
Preserve the complete instrument and receipt record, use the BIR REVIE LOA Verifier, map the issuer, assigned officers, taxpayer, taxable periods, tax types and scope, then open one response register before producing records. The verifier is one authenticity check, not a complete legal-validity conclusion. Raising an objection does not, by itself, stop the audit or later deadlines.
Preserve the authority and service record
Keep the complete authority, covering letter, envelope or electronic transmission, acknowledgment, verifier result and any earlier audit authority. Identify the taxpayer, periods, tax types, officers, group supervisor and issuer. Check the applicable delegation, issuance and service rules; do not assume every office may sign or that a universal 30-day lapse rule applies.
Check replacements and assignments
RMO No. 22-2026 is the BIR’s consolidated and revised 2026 audit program. RMC No. 14-2026 supplies an important transition caveat: a continuity, consolidation or administrative-realignment Replacement eLA is not automatically a new or invalid authority. That does not make every Replacement eLA valid. Test the original authority, taxpayer, taxable periods, authorized scope, current assigned officers, issuer and service record under the rules governing the actual instrument.
CIR v. McDonald’s Philippines Realty Corp. rejected continuation by substitute officers under a mere internal assignment memorandum without the required new or amended LOA. Do not collapse that holding into a rule that every properly issued later Replacement eLA is invalid. Identify the actual defect, put any objection on record, and continue protecting response and protest deadlines.
Use one document-control register
The following is an NLF internal control method, not a BIR-prescribed form. Adapt it to the actual instrument and requests.
| Control point | Capture now | Review test | Escalate when |
|---|---|---|---|
| Authority and service | Complete instrument, case number, issue and receipt record, issuer, assigned officers and group supervisor. | Compare the original, any Replacement eLA, covering notice and REVIE result. | An instrument, signature, named officer, date or service link is missing or inconsistent. |
| Authorized scope | Taxpayer and TIN, taxable periods, tax types, office and stated authority. | Match every request and audit act against the live authority. | A request adds a taxpayer, period, tax type or issue outside the stated authority. |
| Document requests | Request date, exact item, requested date, custodian, available format and response owner. | Check relevance, availability, confidentiality, privilege and whether clarification is needed. | The request is unclear, duplicative, unavailable, overbroad or may expose protected material. |
| Response packages | Index, version, reconciliation, explanatory owner, reviewer and proof of delivery. | Tie schedules to returns and ledgers; distinguish originals, certified copies and working extracts. | Departments conflict, a reconciliation does not close, or the proposed explanation exceeds the records. |
| Audit events | Official communications, meetings, minutes, commitments, submissions and next stated step. | Confirm the record promptly and preserve what was actually agreed or disputed. | The BIR record is inaccurate, a commitment is impracticable, or the process moves to NOD, PAN or FLD/FAN. |
| Management decisions | Issue owner, legal and accounting positions, exposure range, decision date and approval path. | Separate statutory deadlines from internal target dates and commercial decisions. | A position changes, material exposure emerges, settlement is considered, or a separate proceeding begins. |
Coordinate document production so the information is accurate and responsive. Avoid conflicting departmental explanations and preserve historical records without alteration.
Do not confuse audit response with protest
An LOA authorizes examination; it is not the final assessment. A NOD, PAN, FLD/FAN and decision each require a fresh review. For reinvestigation of an FLD/FAN, failing to submit relevant supporting documents within the applicable 60-day period is not merely an automatic conversion into reconsideration. See the formal protest guide before choosing that remedy.
Settlement and further proceedings
Compromise requires statutory eligibility and approval; it is not a routine entitlement. Section 204 excludes criminal violations already filed in court and those involving fraud from its criminal-compromise authority. Other conditions and the particular case still matter. A later collection measure or criminal referral should be assessed separately from the original audit response.
