G.R. No. 255520 , April 21, 2025
COMMISSIONER OF INTERNAL REVENUE, PETITIONER, VS. STRADCOM CORPORATION, RESPONDENT.

FACTS

Stradcom Corporation, under a Build-Own-Operate Agreement with the DOTC, filed its Annual Income Tax Return (AITR) for taxable year 2011 on April 16, 2012, showing no tax due. In July 2013, the BIR, without issuing a Preliminary Assessment Notice (PAN) or Final Assessment Notice (FAN), demanded payment of deficiency income taxes and subsequently issued a Warrant of Distraint and/or Levy and a Warrant of Garnishment against Stradcom. To lift these warrants, Stradcom paid PHP 488,377,342.81 on August 29, 2013.
Stradcom later filed an administrative and subsequently a judicial claim for refund, arguing the tax was illegally collected due to lack of due process. The Court of Tax Appeals (CTA) Division and the CTA En Banc ordered the refund, ruling the collection was invalid for violating statutory assessment procedures. The Commissioner of Internal Revenue (CIR) appealed, arguing that since Stradcom had self-assessed its liability in its AITR, the deficiency assessment procedure was unnecessary, and the collection was for a tax delinquency.

ISSUE

Whether the CTA En Banc erred in holding that Stradcom was denied due process, warranting a refund of the collected tax.

RULING

The Supreme Court denied the CIR’s petition and affirmed the CTA rulings. The Court held that the CIR’s collection efforts constituted a deficiency tax assessment, not merely the collection of a self-assessed or delinquent tax. A deficiency tax arises when the CIR determines a taxpayer’s liability exceeds the amount shown on the return. Here, Stradcom’s AITR for 2011 declared no tax payable. The BIR’s subsequent demand for a substantial sum was therefore a claim for a deficiency, which triggered the mandatory due process requirements under the National Internal Revenue Code and relevant revenue regulations.
These requirements include issuing a Letter of Authority, a Notice for Informal Conference, a PAN, and a FAN before any collection can be enforced. The CIR’s failure to observe these steps before issuing the warrants of distraint and garnishment was a fatal violation of Stradcom’s statutory right to due process. The Court distinguished this case from SMI-Ed Philippines Technology, Inc. v. CIR, cited by the CIR, as that case involved a taxpayer who reported a specific tax due but failed to pay it, constituting a simple delinquency. In contrast, Stradcom reported no tax due, making the CIR’s action an assessment of a deficiency. Consequently, the tax collected without a valid assessment was illegal, and Stradcom was entitled to a refund.
