Petitioner

Bonifacia Sy Po, appearing as petitioner on behalf of the estate/interest of her late husband, Po Bien Sing, challenged the CIR’s deficiency assessments and the CTA’s affirmation of those assessments.

Respondent

The Commissioner of Internal Revenue assessed deficiency income tax and deficiency specific tax against the taxpayer (Po Bien Sing/Silver Cup) and the Court of Tax Appeals affirmed those assessments; the CIR relied on the Finance-BIR-NBI team’s investigation and supporting exhibits.

Applicable Law

Section 16(b) of the National Internal Revenue Code of 1977, as quoted in the decision, governing the Commissioner’s power to assess taxes when required returns or documents are not forthcoming or are believed to be false, incomplete, or erroneous; authorizes assessment on the “best evidence obtainable” and makes assessments prima facie correct.
Statutory provisions for surcharge and interest as applied by the CIR (old provisions cited in the record and their equivalents under the 1977 Code): the 50% surcharge for willful false/fraudulent filing and statutory interest on deficiencies.

Factual Findings Adopted by the Court

Investigation was initiated after a denunciation of Silver Cup for alleged tax evasion; a Finance-BIR-NBI team was directed to investigate.
Subpoenas for accounting records were issued; the taxpayer failed to produce books of accounts for examination.
The investigatory team, aided by local police, entered the factory bodega and seized various alcohol products (inventory lists and volumes documented in multiple exhibits).
Sworn statements of former employees and inventory/seizure records established that Silver Cup used large quantities of untaxed alcohol (the team determined 20,105 drums or 81,288,787 proof liters for 1964–1970) and documented patterns of concealment and false entries.
Based on the team’s computations, the CIR assessed specific tax and deficiency income taxes for the indicated years, and imposed statutory surcharge and interest.

Procedural Posture and Assignments of Error

Petitioner raised three principal assignments of error before the Supreme Court: (1) that the CTA erred in holding petitioner failed to present relevant and competent evidence to rebut discrepancies and illegality of assessments; (2) that the CTA’s decision contravened established Supreme Court doctrines; and (3) that the CTA erred in finding the assessed deficiency taxes were incurred by Po Bien Sing.

Legal Standards Applied

Findings of fact by the Court of Tax Appeals are binding on the Supreme Court and may only be disturbed when unsupported by substantial evidence.
Section 16(b) authorizes the CIR to assess taxes on the “best evidence obtainable” where returns are not filed or are believed false or incomplete; if a taxpayer fails to present required records, the CIR may compute or amend returns from available information and such assessments are prima facie correct.
The taxpayer bears the burden to prove the correct tax liability once the CIR’s assessment is challenged; an appellant must provide a full and fair disclosure of pertinent data to demonstrate the correct liability. Assessments are presumed correct and will stand absent satisfactory rebuttal or proof of irregularity in the assessment process.

Evidence and Findings on Fraudulent Conduct

The investigatory record included sworn statements by former employees (e.g., Nelson S. Po and Alfonso Po) describing concealed storage, secret tunnels in the bodega, and methods by which untaxed alcohol was brought in and used while the revenue inspector was absent or misled.
Testimony and sworn statements indicated false entries were made in official register books under the direction of the owner, and that operations with untaxed alcohol were timed to avoid the revenue inspector.
The CTA and the Supreme Court found these indicators of intentional evasion and fraudulent conduct were not satisfactorily rebutted by petitioner.

Reliance on Evidence to Compute Tax Liability

The CIR’s assessments were based on quantifiable evidence obtained by the investigatory team: quantities of untaxed alcohol seized and documented, and sworn employee statements regarding usage and concealment.
The CTA’s findings reproduced the team’s accounting of alcohol usage and the derived tax liabilities (specified figures for the specific tax aggregate an

Case Syllabus (G.R. No. 81446)

Procedural History

Petition to the Supreme Court from the decision of the Court of Tax Appeals (CTA) dated September 30, 1987, which affirmed earlier assessment decisions of the Commissioner of Internal Revenue (CIR).
Commissioner of Internal Revenue issued assessment letters dated August 16, 1972 and September 26, 1972 ordering payment by petitioner of:
- Deficiency income tax for 1966 to 1970 in the amount of P7,154,685.16; and
- Deficiency specific tax for January 2, 1964 to January 19, 1972 in the amount of P5,595,003.68 (as stated in the assessment letters).
Petitioner protested via letters dated October 9 and October 30, 1972; protests were referred for reinvestigation.
Reinvestigation report dated August 13, 1981 recommended reiteration of assessments due to failure to present books of account.
Warrants of distraint and levy issued September 10, 1981; these were received by petitioner on October 14, 1981, which petitioner treated as denial of her protest.
Petitioner appealed to the CTA on October 29, 1981. CTA affirmed the CIR’s assessments on September 30, 1987.
Petition for certiorari filed in the Supreme Court (G.R. No. 81446); decision of the Supreme Court dated August 18, 1988 (Opinion by Justice Sarmiento) denying the petition and affirming CTA decision; costs taxed against petitioner.
CTA decision was penned by Associate Judge Alex Z. Reyes and concurred in by Presiding Judge Amante Filler; Associate Judge Constante C. Roaquin was on leave.
Supreme Court decision concurred in by Melencio-Herrera (Chairperson), Paras, and Padilla, JJ.

Facts Found by the CTA and Adopted by the Supreme Court

Silver Cup was engaged in manufacture and sale of compounded liquors, using alcohol and other ingredients as raw materials during the taxable years 1964 to 1972.
A denunciation alleging tax evasion prompted the Secretary of Finance (Cesar Virata) to direct a Finance-BIR-NBI team constituted under Finance Department Order No. 13-70 dated February 19, 1971 to investigate; memorandum dated April 2, 1971 instructed the team to conduct the corresponding investigation.
