Commissioner of Internal Revenue vs. Fitness by Design, Inc.

A Final Assessment Notice is void if it does not contain a definite due date for payment and fails to state in writing the factual and legal bases of the assessment, as mandated by Section 228 of the National Internal Revenue Code and Revenue Regulations No. 12-99; the requirement is substantive and essential to afford the taxpayer due process in preparing an effective protest.

Fitness by Design, Inc. filed its Annual Income Tax Return for taxable year 1995 on April 11, 1996, declaring it was in the pre-operating stage. On March 17, 2004, the Commissioner of Internal Revenue issued a Final Assessment Notice assessing deficiency income tax, value-added tax, and documentary stamp tax totaling ₱10,647,529.69, allegedly based on unreported sales discovered through a confidential informant. The assessment was received by Fitness on June 9, 2004.

• Filing of Return and Initial Assessment: Fitness filed its 1995 Annual Income Tax Return on April 11, 1996, reporting no income as it claimed to be in the pre-operating stage. On June 9, 2004, it received a Final Assessment Notice dated March 17, 2004, issued under Letter of Authority No. 00002953, assessing total deficiency taxes of ₱10,647,529.69 based on alleged unreported sales of ₱7,156,336.08.
• Content of the Final Assessment Notice: The notice computed deficiencies for income tax, value-added tax, and documentary stamp tax, including surcharges and interest. However, it stated that "the interest and the total amount due will have to be adjusted if paid prior or beyond April 15, 2004." It also directed payment "within the time shown in the enclosed assessment notice," but the enclosed assessment was unaccomplished.
• Protest and Collection Efforts: Fitness filed a protest on June 25, 2004, arguing prescription and lack of basis for the fraud allegation. The Commissioner denied receiving the protest and, on February 2, 2005, issued a Warrant of Distraint and/or Levy.
• Proceedings Before the CTA: Fitness filed a Petition for Review before the CTA First Division on March 1, 2005. The First Division granted the petition, canceling the assessment and warrant. The Commissioner appealed to the CTA En Banc, which affirmed the cancellation.
• Evidence on Fraud: During the proceedings, Fitness' president testified the company was in pre-operating stage in 1995, importing equipment for market testing without profit. The BIR Group Supervisor admitted that the information from the confidential informant did not indicate that Fitness' failure to report income was deliberate.

• Validity of Assessment: The Final Assessment Notice complied with Section 228 of the National Internal Revenue Code and Revenue Regulations No. 12-99 because it stated the facts, jurisprudence, and law on which the assessment was based; the due date for payment is not a substantive requirement for validity.
• Due Date Specification: April 15, 2004 was sufficiently indicated as the due date, as evidenced by the statement that interest and total amount would be adjusted if paid prior or beyond that date.
• Fraud Assessment and Prescription: The ten-year prescriptive period under Section 222(a) applied because Fitness filed a false and fraudulent return with intent to evade tax by intentionally failing to reflect true sales; the assessment was discovered through a confidential informant.
• Finality of Assessment: The assessment became final and executory because Fitness failed to file a valid protest within the 30-day reglementary period; the alleged protest was not found in BIR records.

• Invalidity for Lack of Definite Demand: The Final Assessment Notice was merely a request, not a valid demand for payment, because it failed to state a definite due date and the amount due was indefinite (subject to adjustment based on payment date), violating the requirement that an assessment must be a definite demand for a fixed amount.
• Due Process Violation: The notice violated due process under Section 228 because it did not contain the factual and legal bases for the assessment, particularly the specific details of the alleged fraud, preventing Fitness from preparing an effective protest.
• Prescription: The assessment prescribed under the three-year rule under Section 203 because the return was not fraudulent; the Commissioner failed to allege and prove specific fraudulent acts.

• Validity of Final Assessment Notice: Whether the Final Assessment Notice issued against Fitness by Design, Inc. is a valid assessment under Section 228 of the National Internal Revenue Code and Revenue Regulations No. 12-99.
• Definite Due Date Requirement: Whether the absence of a definite due date for payment in the Final Assessment Notice renders it invalid.
• Fraud Allegations and Due Process: Whether the Commissioner sufficiently alleged and proved fraud in the assessment notice to justify the ten-year assessment period under Section 222(a) and comply with due process requirements.

• Validity of Final Assessment Notice: The Final Assessment Notice was invalid. Section 228 of the National Internal Revenue Code and Revenue Regulations No. 12-99 mandatorily require that the formal letter of demand state the facts, law, and rules on which the assessment is based; failure to comply renders the assessment void. This requirement is substantive, not merely formal, as it enables the taxpayer to file an effective protest and satisfies the constitutional guarantee of due process.
• Definite Due Date Requirement: The notice was invalid for lack of a definite due date. The statement that the amount would be adjusted if paid prior or beyond April 15, 2004 indicated that April 15, 2004 was merely a reckoning date for penalties, not a fixed due date for payment. The direction to pay "within the time shown in the enclosed assessment notice" was ineffective because the enclosure was unaccomplished. A valid assessment must be a definite demand for payment of a fixed amount within a specific period to allow the taxpayer to determine when remedies accrue.
• Fraud Allegations and Due Process: The Commissioner failed to sufficiently allege fraud in the assessment notice. Fraud is a question of fact that must be clearly stated to enable the taxpayer to contest it effectively; it cannot be presumed. The BIR supervisor admitted that the investigation did not show deliberate intent to evade taxes, and the assessment notice and attachments did not impute specific fraudulent acts.

• Due Process in Tax Assessment (Section 228, NIRC) — The Commissioner must inform the taxpayer in writing of the law and facts on which the assessment is based; otherwise, the assessment is void. This is a mandatory and substantive requirement, not merely directory, designed to enable the taxpayer to make an effective protest. The word "shall" in Section 228 makes this mandatory.
• Definite Demand Requirement — A valid assessment must contain a definite demand for payment of the tax due within a specific period. Conditional statements (e.g., amounts subject to adjustment) or references to due dates in unaccomplished enclosures render the assessment indefinite and invalid.
• Distinction Between False and Fraudulent Returns — A "false return" involves a deviation from the truth, whether intentional or not, while a "fraudulent return" implies intentional or deceitful entry with intent to evade taxes. Fraud must be alleged and proven; it cannot be presumed.
• Substantial Compliance Doctrine — Substantial compliance with Section 228 is permissible only if the taxpayer is subsequently apprised in writing of the factual and legal bases of the assessment in a manner that enables preparation of an effective protest.

• "To avail of the extraordinary period of assessment in Section 222(a) of the National Internal Revenue Code, the Commissioner of Internal Revenue should show that the facts upon which the fraud is based is communicated to the taxpayer."
• "The word 'shall' in Section 228 of the National Internal Revenue Code and Revenue Regulations No. 12-99 means the act of informing the taxpayer of both the legal and factual bases of the assessment is mandatory."
• "A final assessment notice provides for the amount of tax due with a demand for payment... This demand for payment signals the time when penalties and interests begin to accrue against the taxpayer and enabling the latter to determine his remedies."
• "The disputed Final Assessment Notice is not a valid assessment. First, it lacks the definite amount of tax liability for which respondent is accountable... Second, there are no due dates in the Final Assessment Notice."

• Commissioner of Internal Revenue v. United Salvage and Towage (Phils.), Inc., 738 Phil. 335 (2014) — Followed for the rule that a final assessment notice containing only a tabulation of taxes without further details is insufficient.
• Commissioner of Internal Revenue v. Enron Subic Power Corp., 596 Phil. 229 (2009) — Followed for the mandatory nature of Section 228 requirements and the distinction between the issuance of a notice and its contents.

• Section 203, National Internal Revenue Code of 1997 — Provides the general three-year prescriptive period for assessment.
• Revenue Regulations No. 12-99, Section 3.1.4 — Requires the formal letter of demand and assessment notice to state the facts, law, rules, and regulations, or jurisprudence on which the assessment is based.
