G.R. No. 264192 - People vs. Rebecca Tiotangco

Rebecca S. Tiotangco was charged with violations of Section 255 of the 1997 National Internal Revenue Code (Tax Code) for willfully failing to supply correct and accurate information in her income tax returns for the taxable years 2008 and 2010.
The criminal charges were consolidated under CTA Criminal Case Nos. O-602 and O-605, with the allegations revolving around the non-declaration of substantial amounts of income resulting in significant deficiency taxes.
Evidence presented by the prosecution included a Letter of Authority, a Preliminary Assessment Notice (PAN), and a Formal Letter of Demand/Final Assessment Notice (FLD/FAN) issued by the Bureau of Internal Revenue (BIR) but with disputed service, as the defendant denied having received these notices.

At arraignment, after posting bail, Rebecca pleaded “not guilty,” leading to a trial on the merits.
On February 26, 2020, the CTA Division found Tiotangco guilty beyond reasonable doubt on two counts of violation.
Despite the criminal conviction, the CTA Division ruled that no proper determination of Rebecca’s civil liabilities for unpaid deficiency taxes could be made due to the absence of a valid final assessment by the Commissioner of Internal Revenue (CIR).

The case raised the issue of whether a final assessment is necessary within the same criminal action for the imposition of civil liability.
Under the expanded jurisdiction granted by Republic Act (RA) No. 9282, the criminal action is deemed to automatically carry with it the corresponding civil suit for tax collection.
The CTA Division, on reconsideration and subsequent review by its En Banc, maintained that the lack of a valid assessment precluded the imposition of civil liability, thereby reinforcing the requirement under Section 205 of the Tax Code.

The People, through the Office of the Solicitor General (OSG), filed a Petition for Review on Certiorari under Rule 45 of the Rules of Court.
The petition sought to reverse the CTA Division and En Banc decisions which denied the imposition of civil liability owing to the absence of a formal assessment.
The core dispute centered on reconciling the requirements of Section 205 of the Tax Code with the provisions of RA No. 9282 and Section 11, Rule 9 of the Revised Rules of the Court of Tax Appeals regarding the simultaneous institution of civil and criminal actions.

Whether a final assessment by the Commissioner of Internal Revenue is a necessary precondition for imposing civil liability for unpaid deficiency taxes in a criminal tax case.

Whether the absence of a valid assessment, due to the failure of the prosecution to prove that the assessment notices were received, violates the accused’s right to due process.
How to reconcile the mandatory language of Section 205 of the Tax Code, which prescribes a final assessment before the determination of civil liability, with RA No. 9282 that deems the criminal action as carrying an automatic civil action for tax collection.

Whether the criminal action, inherently considered a collection case for unpaid taxes, allows for the determination of civil liability by using competent evidence other than a formal assessment.
The appropriate procedural mechanism to address the dispute on the taxpayer’s civil liability within the framework of a joint criminal and civil proceeding.
