Notice of Discrepancy

Function in the Assessment Process

A Notice of Discrepancy is the BIR's written communication that informs a taxpayer of discrepancies found during an authorized audit before the ordinary issuance of a Preliminary Assessment Notice. It belongs to the pre-assessment stage and is meant to give the taxpayer a real opportunity to explain, reconcile, or document the questioned items before the government formally proposes a deficiency assessment.

The notice ordinarily follows an examination conducted under a valid Letter of Authority. The authority to examine comes from the Letter of Authority, not from the Notice of Discrepancy, so the notice cannot cure an audit conducted by officers who were not properly authorized to investigate the taxpayer and the taxable period involved.

The discrepancy may involve underdeclared sales or receipts, unsupported deductions, disallowed expenses, unsubstantiated input tax, unpaid withholding tax, incorrect tax rates, classification issues, reconciliation differences, or mismatches between returns, books, third-party information, and other tax records. The notice should identify the tax type, taxable period, factual basis, and amount or computation sufficient to let the taxpayer understand what must be answered.

The Notice of Discrepancy is not itself an assessment. It is not a demand for payment, does not fix a final tax liability, does not start the period to file a protest, and is not the decision that may be appealed to the Court of Tax Appeals.

Place in the Sequence of Notices

The Notice of Discrepancy cannot substitute for the Preliminary Assessment Notice because the PAN is the formal pre-assessment notice contemplated by the NIRC due process rule. It also cannot substitute for the Formal Letter of Demand and Final Assessment Notice because only the formal assessment states a final deficiency and triggers the taxpayer's duty to protest within thirty days.

The PAN may differ from the Notice of Discrepancy if the BIR revises its computations after discussion or review. The change is permissible only if the taxpayer is still informed in writing of the facts and law supporting the proposed and final assessment at the required stages.

Contents and Quality of the Notice

A useful Notice of Discrepancy is not a bare conclusion that a deficiency exists. It should give enough detail for the taxpayer to determine the source of the proposed adjustment, the tax involved, the taxable period, the computation used, and the documents or explanations needed to refute the finding.

The notice may attach schedules, reconciliation worksheets, comparison tables, or summaries of disallowances. The schedules are important because an assessment process is meaningful only if the taxpayer can trace the discrepancy to concrete figures, records, or transactions.

The notice should be connected to the scope of the Letter of Authority. A discrepancy for a tax type, period, or taxpayer not covered by the authority raises a separate due process and authority issue because revenue officers may examine only what they were authorized to examine.

A notice that merely states an amount without showing the nature of the discrepancy weakens the taxpayer's opportunity to be heard. The taxpayer's right is not satisfied by a ritual notice if the taxpayer cannot understand what factual or legal issue must be answered.

Discussion Period and Taxpayer Participation

Under the assessment regulations, the discussion of discrepancies is an administrative stage that should not be allowed to indefinitely delay the assessment process. The period is generally counted from the taxpayer's receipt of the Notice of Discrepancy and is intended for explanation, submission of documents, and reconciliation of findings.

The taxpayer may agree with all findings, disagree with all findings, or accept some items while contesting others. Partial agreement should be carefully reflected in the records because payment of an uncontested item does not necessarily concede unrelated adjustments.

• Full agreement. If the taxpayer accepts the discrepancies and pays the deficiency, the matter may be closed for the covered items, subject to proper recording of the tax type, period, amount, surcharge, interest, and compromise penalties if applicable.
• Partial agreement. If only some items are accepted, the taxpayer may pay the uncontested portion and submit documents or explanations for the disputed items.
• Full disagreement. If the taxpayer contests the findings, the taxpayer may submit reconciliations, source documents, legal arguments, and other records that directly answer the identified discrepancies.
• No participation. If the taxpayer ignores the notice, the BIR may proceed to the next stage based on available records, but the taxpayer still retains the statutory right to respond to a PAN and protest a FAN when those notices are later issued.

The response to a Notice of Discrepancy is not the protest contemplated for a final assessment. It is a pre-assessment explanation, so it does not replace the thirty-day protest required after receipt of the Formal Letter of Demand and Final Assessment Notice.

Documents submitted during the discrepancy discussion may become part of the administrative record. A taxpayer who gives complete and organized explanations at this stage may narrow the issues before the PAN, while a taxpayer who withholds available records may face a more difficult factual dispute later.

Relation to Statutory Due Process

Section 228 of the NIRC requires that a taxpayer be informed in writing of the law and facts on which an assessment is made; otherwise, the assessment is void. The Notice of Discrepancy supports that due process policy by giving an earlier chance to know and answer the audit findings, but the formal validity of the assessment still depends on proper compliance with the required PAN and FAN stages, unless a statutory exception to PAN applies.

Tax due process has both notice and opportunity components. The notice component requires intelligible written information about the factual and legal bases of the deficiency, while the opportunity component requires a real chance to answer at the stage required by law or regulation.

Because the BIR must follow its own assessment regulations, omission of a required Notice of Discrepancy may be raised as an administrative due process defect. The objection is strongest when the omission deprives the taxpayer of the regulatory opportunity to discuss and reconcile the findings before the PAN is issued.

A belated Notice of Discrepancy issued after the PAN does not perform the same function because the sequence matters. The notice is designed to come before the proposed assessment, not after the proposed deficiency has already been formalized.

The defect in the Notice of Discrepancy stage must still be distinguished from defects in the PAN, FAN, or decision on protest. A taxpayer who receives a valid FAN must observe the protest period even if the taxpayer also asserts that the earlier discrepancy process was flawed.

Service and Receipt

Receipt matters because the period for discussion and submission of explanations runs from the taxpayer's receipt of the Notice of Discrepancy. Service should be made on the taxpayer or a duly authorized representative in a manner that can establish actual or constructive receipt.

Delivery to an employee, accountant, consultant, or agent is effective only when the circumstances show authority to receive the notice for the taxpayer. If the person served had no authority and the taxpayer was deprived of participation, the taxpayer may contest the adequacy of notice.

Actual participation by the taxpayer after receiving the notice may defeat a purely technical objection to service. The controlling inquiry is whether the taxpayer was actually informed of the discrepancies and given a meaningful chance to answer them at the proper time.

Effect on Prescription and Collection

A Notice of Discrepancy does not interrupt or suspend the prescriptive period for assessment. Prescription is affected only by events recognized by law, such as a valid waiver executed before the period expires or circumstances that legally allow assessment beyond the ordinary period.

The BIR must still issue the formal assessment within the applicable prescriptive period. A Notice of Discrepancy sent near the end of the period does not preserve the government's right to assess if the final assessment is issued too late.

The notice also does not authorize collection by distraint, levy, civil action, or other enforcement remedies. Collection remedies presuppose an assessment or liability that has become collectible under the NIRC, not a mere initial discrepancy communication.

Interaction with PAN Exceptions

The NIRC recognizes situations where a Preliminary Assessment Notice is not required, such as certain mathematical errors, withholding discrepancies, carry-over and refund inconsistencies, unpaid excise taxes on excisable articles, and transfers of tax-exempt imported or locally purchased articles to non-exempt persons. In those cases, the statutory rule allows the BIR to proceed without a PAN, but the taxpayer must still be informed in writing of the law and facts supporting the assessment.

The Notice of Discrepancy procedure normally applies to audit findings developed under a Letter of Authority before a PAN. It does not convert every PAN-exception case into a PAN-required case, and it does not eliminate the BIR's obligation to state the bases of the final assessment when the law requires written reasons.

If the case is not within a PAN exception, the ordinary sequence remains important: discrepancy discussion, PAN, taxpayer response, then FAN and demand if the BIR maintains the deficiency. Skipping the PAN when no exception applies is a statutory due process defect independent of any issue about the Notice of Discrepancy.

Substantive Role in Later Disputes

The Notice of Discrepancy helps define the factual issues that may later appear in the PAN and FAN. It may show what the BIR initially found, what documents were requested, what explanations were offered, and whether the taxpayer had a meaningful opportunity to participate.

The notice is not conclusive evidence that a deficiency exists. The presumption of correctness generally attaches to a valid assessment, not to an initial discrepancy notice that merely invites discussion.

If a later PAN or FAN includes items never meaningfully disclosed before, the validity of the later notice depends on whether that later notice itself states the required facts and law and gives the taxpayer the required chance to answer. A new item first appearing in a FAN, where a PAN was required for that item, creates a due process problem because the taxpayer was deprived of the pre-assessment response stage.

Admissions made by the taxpayer during the discrepancy discussion may be used in evaluating the case, but they should be read according to their actual scope. A reconciliation of sales, a concession of a computational error, or a payment of an uncontested amount should not be expanded beyond the tax type, period, and issue actually covered.

Practical Legal Consequences

The Notice of Discrepancy stage is designed to reduce unnecessary assessments by allowing factual reconciliation before the formal assessment process hardens. It is especially important in cases involving matching differences, timing issues, related-party accounts, input tax documentation, withholding tax certificates, and accounting classifications.

For the taxpayer, the central legal consequence is an early opportunity to create a record that the BIR must consider before moving to the PAN. For the BIR, the central consequence is a duty to communicate the discrepancy clearly and to allow the taxpayer to be heard in the manner required by its own regulations.

Once the case proceeds to a PAN or FAN, the taxpayer must respond under the rules governing those later notices. The earlier Notice of Discrepancy remains relevant to due process and factual context, but it does not displace the statutory periods and remedies attached to the formal assessment stages.
