Atlas Legal published detailed commentary on the South Korean Supreme Court’s December 2025 ruling that falsely issuing an amended tax invoice constitutes a criminal offense under the Punishment of Tax Evaders Act. Attorney Taejin Kim analyzes Case No. 2025Do10232, its reversal of two lower court acquittals, and the practical compliance implications for businesses operating in South Korea.
Case Background
The case involved a construction company operator who issued a negative (minus) amended tax invoice to cancel an original invoice, without any actual contract rescission or return of goods. The Cheongju District Court acquitted the defendant at both first instance and on appeal (Case No. 2024No1141), holding that applying criminal liability to amended invoices would violate the principle of legality. The Supreme Court reversed those acquittals in December 2025 and remanded the case for retrial.
The Supreme Court’s Three-Part Rationale
The Supreme Court held that amended tax invoices qualify as “tax invoices” under Article 10(1)(1) of the Punishment of Tax Evaders Act on three grounds (Supreme Court of South Korea, December 11, 2025, Case No. 2025Do10232). First, an amended invoice serves the same functions as a standard invoice — it evidences a supply transaction and forms the basis for calculating output and input VAT. Second, under Article 32(7) of the Value-Added Tax Act, an amended invoice is by definition a “corrected tax invoice,” incorporating all mandatory fields required under Article 32(1). Third, fraudulently issuing an amended invoice undermines the integrity of the tax invoice system and impairs VAT assessment and collection, giving rise to the same need for criminal deterrence as falsifying a standard invoice. The Court confirmed this reasoning applies equally to negative amended invoices.
Why the Lower Courts’ Acquittals Were Reversed
The lower courts reasoned that because the Value-Added Tax Act uses separate terminology for standard and amended invoices, extending criminal liability to amended invoices would constitute impermissible analogical interpretation under Korean criminal law. The Supreme Court rejected this view. Article 32(8) of the VAT Act, which delegates procedural rules for both document types to Presidential Decree, was not intended to place amended invoices outside the general category of “tax invoice.” The terminological distinction reflects a structural drafting choice, not a decision to exclude amended invoices from the scope of criminal punishment.
Distinction from the 2020Do118 Ruling on Fictitious Invoices
A separate Supreme Court decision — Case No. 2020Do118 (October 15, 2020) — held that issuing a negative amended invoice solely to cancel a prior fictitious invoice (one issued for a transaction that never occurred) does not constitute an independent offense under Article 10(3)(1) of the Punishment of Tax Evaders Act. That cancellation is treated as a corrective measure rather than a new criminal act. However, the original fictitious invoice offense is already complete at the moment of issuance and is entirely unaffected by the subsequent cancellation. The 2025Do10232 and 2020Do118 decisions address distinct fact patterns and legal provisions and must not be conflated.
Compliance Implications for Businesses in South Korea
Following the 2025Do10232 ruling, businesses that issue amended tax invoices as part of routine accounting or dispute resolution must reassess their practices. High-risk conduct includes issuing a negative amended invoice without a genuine contract rescission or goods return, reducing the recorded supply value to match payment actually received, and retroactively cancelling completed transactions without contemporaneous documentation. Before issuing any amended tax invoice, companies should confirm that a legitimate ground under Article 70 of the Enforcement Decree of the VAT Act exists, that the recorded supply change accurately reflects the actual transaction, and that supporting documentation — such as a rescission agreement or return confirmation — is in place.
