People v. E & D Parts Supply: An Acquittal Doesn't Automatically Erase a Tax Bill

An acquittal in a BIR criminal tax case does not, by itself, wipe out the taxpayer’s civil liability for the underlying deficiency tax — because that liability is created by law, not by the criminal charge. That is the doctrine the Supreme Court reaffirmed in People v. E & D Parts Supply, Inc. and Margaret L. Uy (G.R. No. 259284, January 24, 2024). In this particular case, however, the company still owed nothing, because the assessment behind the charges was void for a separate reason: it was issued under a Memorandum of Assignment instead of a valid Letter of Authority.

Case details #

What happened #

The Office of the Solicitor General, on behalf of the People of the Philippines, filed criminal informations before the Court of Tax Appeals (CTA) against E & D Parts Supply, Inc. and Margaret L. Uy, identified in the case as the company’s treasurer. The charges alleged willful failure to file income tax returns and to pay income tax and value-added tax, in violation of Section 255 of the National Internal Revenue Code (NIRC), in relation to Sections 253(d) and 256.

At trial, two separate problems surfaced for the prosecution. First, the evidence did not establish that Uy held a position — or exercised direct, active participation — that made her a “responsible officer” of the corporation during the periods covered by the charges; the prosecution simply did not identify which corporate officers were in place when the alleged violations occurred. Second, E & D Parts Supply argued that the underlying deficiency assessment was void from the start: the revenue officer who continued the audit of its books had been authorized only by a Memorandum of Assignment, not by a Letter of Authority (LOA) — the document BIR Revenue Memorandum Order (RMO) No. 43-90 and Section 6(A) of the NIRC require before an examiner may proceed with an audit.

The CTA Division acquitted Uy for insufficiency of evidence and, because the corporate assessment rested on an invalid LOA, found no basis to hold the corporation civilly liable for the assessed deficiency taxes either. The CTA En Banc affirmed. The People elevated the case to the Supreme Court on a petition for review on certiorari, arguing that even if the criminal charges failed, the corporation’s civil liability to pay the assessed taxes should have survived the acquittal.

The issue before the court #

The Supreme Court had to resolve two distinct questions: first, whether an acquittal in a criminal tax case automatically extinguishes the taxpayer’s civil liability for the deficiency tax that gave rise to the charges; and second, whether the specific assessment against E & D Parts Supply could still be enforced given the defect in the revenue officer’s authority to conduct the audit.

The ruling #

The Supreme Court denied the petition, but it used the case to restate a settled — and easily misunderstood — principle: acquittal in a tax case does not by itself erase the taxpayer’s civil tax liability, because that liability does not come from the crime charged. As the Court put it in the decision:

“The taxpayer’s obligation to pay the tax is created by law; it does not arise from the offense of tax evasion.”

And, more directly on the effect of an acquittal:

“[A]n acquittal of the accused or the dismissal of the criminal case for tax law violation will not result in the extinction of their civil liability for deficiency taxes.”

This tracks a doctrinal line the Court has followed since Republic v. Patanao (1967), which held that the “liability to pay taxes arises from the fact… that one has engaged himself in business, and not because of any criminal act committed by him,” and Proton Pilipinas Corp. v. Republic (2006), which described the duty to pay tax as a statutory obligation existing independently of — and prior to — any criminal proceeding for evading it. Because the two liabilities spring from different sources (one from law, one from an offense), an acquittal on the criminal charge, standing alone, does not discharge the civil one.

That general rule did not save the BIR’s collection effort in this specific case, though. The Court agreed with the CTA that the assessment against E & D Parts Supply could not be enforced because the examination that produced it was never properly authorized. A Memorandum of Assignment is not a substitute for a Letter of Authority; without a valid LOA naming the revenue officer and the taxable period under audit, the resulting assessment is void, and a void assessment creates no tax liability to collect — civil or otherwise. The two holdings work together rather than in tension: the general doctrine (acquittal does not erase civil liability) remained intact, but there was no valid assessment left standing for that doctrine to attach to. The decision does not report any separate or dissenting opinion.

Our insights #

This decision is a useful corrective against a common misreading of BIR enforcement: that beating a tax evasion charge in the CTA means the tax bill disappears too. It does not, as a general matter — the Court’s reasoning traces directly back to Patanao and Proton Pilipinas, and PwC’s tax practice has previously flagged the same distinction in its commentary on responsible-officer liability, noting that the corporation’s assessment and the individual officer’s criminal exposure are analyzed separately under Sections 253(d) and 256 of the NIRC.

What makes E & D Parts Supply worth reading past the headline is that the taxpayer still won — not because the general doctrine favored it, but because the BIR’s own audit procedure failed on an independent, well-established ground: the LOA requirement under RMO No. 43-90. That requirement has anchored a long run of Supreme Court decisions voiding assessments issued without one, and this case simply applies it again in a criminal-case setting rather than a pure civil refund or deficiency dispute. Taxpayers and practitioners sometimes treat the “acquittal erases liability” argument and the “void LOA” argument as one and the same; this case shows they are two separate defenses, and only one of them worked here.

What this means for taxpayers #

A corporation facing both a criminal tax case and a related civil deficiency assessment should not assume that winning the criminal case resolves the civil one — the two are legally distinct, and the BIR (or the courts, through a separate civil action or offsetting the acquittal judgment) can in principle still pursue the tax due. The defense that actually matters procedurally is verifying, at the outset of any audit, that the revenue officer conducting it holds a valid Letter of Authority naming that officer and the specific taxable period — not a Memorandum of Assignment, a Letter Notice, or any other internal reassignment document. If that authority is missing or defective, the resulting assessment, and any criminal case built on it, is vulnerable regardless of how the acquittal doctrine would otherwise apply.

For officers and treasurers named in a criminal tax case, the prosecution also carries its own burden: it must show the individual actually held a position of responsibility and had direct, active participation in — or the power to prevent — the violation during the period charged, not simply that they carried a title at some point.

Summary #

People v. E & D Parts Supply confirms that an acquittal in a BIR criminal tax case does not, on its own, extinguish civil liability for the underlying deficiency tax, because that liability arises from law rather than from the offense — a doctrine traceable to Republic v. Patanao and Proton Pilipinas Corp. v. Republic. In this case, though, the taxpayer still avoided liability because the assessment itself was void: the audit had proceeded on a Memorandum of Assignment rather than a valid Letter of Authority under RMO No. 43-90. The two issues — the acquittal doctrine and the LOA defect — are separate defenses, and taxpayers should not conflate them.
