Case name: 양도소득세부과처분취소

Official text on the National Law Information Center

  1. Question

    Where the tax authority gave no advance notice of assessment, or assessed before the pre-assessment reconsideration request or its decision, is the assessment unlawful, and what conditions make it procedurally justified under Article 81-15(3)(iii) of the Framework Act on National Taxes, and who must prove them?

  2. Holding

    In principle, an assessment made without giving the taxpayer a chance at pre-assessment reconsideration is unlawful, unless a special circumstance excludes the advance notice or permits a direct assessment. The three-month exception in Article 81-15(3)(iii) of the Framework Act on National Taxes does not cover a case where the tax authority neglected tax administration for a long time without proper reason and served the advance notice only when the assessment limitation period was about to expire. For the exception to hold, a further proper reason must be found, such as unavoidable circumstances not attributable to the tax authority that left no time for reconsideration before the period expired, and the tax authority must prove it.

    과세관청이 정당한 사유 없이 스스로 과세행정을 장기간 해태하여 부과제척기간 만료일이 임박한 시점에 과세예고통지를 한 경우, 이는 과세관청이 납세자에게 과세전적부심사의 기회를 부여하지 아니한 채 과세처분을 할 수 있는 예외사유에 해당하는지 여부(소극) / 과세관청이 국세기본법 제81조의15 제3항 제3호의 사유를 들어 납세자에게 과세전적부심사의 기회를 부여하지 아니한 채 과세처분으로 나아간 것이 절차상 정당성을 갖추었다고 보기 위한 요건 및 이에 관한 증명책임의 소재(=과세관청)

    따라서 과세관청이 국세기본법 제81조의15 제3항 제3호의 사유를 들어 납세자에게 과세전적부심사의 기회를 부여하지 아니한 채 과세처분으로 나아간 것이 절차상 정당성을 갖추었다고 하려면, 과세관청의 귀책사유 없이 부득이한 사정으로 부과제척기간의 만료일이 임박하게 되었고 이로 인하여 부과제척기간의 만료 전까지 과세전적부심사를 거칠 시간적 여유가 없게 되었다는 등의 정당한 사유가 추가로 인정되어야 하고

    Unofficial English translation

    Accordingly, for it to be held that the tax authority's proceeding with a tax assessment without affording the taxpayer an opportunity for pre-assessment review, on the ground of Article 81-15, paragraph (3), subparagraph 3 of the Framework Act on National Taxes, satisfies procedural propriety, an additional justifiable ground must be recognized, such as that, due to inevitable circumstances not attributable to the tax authority, the expiration date of the assessment exclusion period became imminent, and that, as a result, there was no time to undergo pre-assessment review before the expiration of the assessment exclusion period, and

    The party asserting Stated in the decision

    이에 관하여는 과세관청이 증명하여야 한다

    The tax authority must prove this
  8. Open question and revisit condition

    What circumstances count as unavoidable circumstances not attributable to the tax authority that left no time for pre-assessment reconsideration before the limitation period expired?

    The remand judgment of the Seoul High Court, on the record of what the tax authority did before serving the advance notice, will show how the added requirement works in practice. Any amendment to Article 81-15 of the Framework Act on National Taxes, or a later decision departing from Supreme Court Decision 2025Du33014, would require this entry to be read again.

Cross-family AI independent reading & axis check

6 of 8 axes matched GPT-6 Astra (OpenAI, codex CLI) · 2026-10-24

A reader from another model family (GPT-6 Astra), given the official text but not the primary reading, agreed on 6 of the 8 axes; the readings differed on axis 7 (burden of proof), axis 8 (open question and revisit condition).

Axis 7 (Burden of proof): Primary “The party asserting” vs Independent “The opposing party”

The source assigns proof to the tax authority, which can be labeled the asserting party when invoking the exception or the opposing party when viewed from the taxpayer's challenge.

이에 관한 증명책임의 소재(=과세관청)

Axis 8 (Open question and revisit condition): Primary “What circumstances count as unavoidable circumstances not attributable to the tax authority that left no time for pre-assessment reconsideration before the limitation period expired?” vs Independent “Did unavoidable circumstances without fault on the tax authority's part actually leave insufficient time for pre-assessment review in this case?”

The primary reading asks what circumstances qualify as unavoidable and without fault, while the independent reading asks whether such circumstances actually existed in this case.

Lower-court contrast & scope of application

Lower-court reading vs. Supreme Court holding

Lower-court context: The Seoul High Court, in its judgment of 26 June 2025 (2024Nu41306), rejected the plaintiff's claim that the assessment was procedurally unlawful for depriving it of pre-assessment reconsideration. It reasoned that Article 81-15(3)(iii) of the Framework Act on National Taxes allows the reconsideration to be omitted whenever the period from the date of the advance notice to the expiry of the assessment limitation period is three months or less, and that considering whether and to what extent the tax authority was at fault is not appropriate.

Supreme Court standard: The Supreme Court held that the court below erred in rejecting the claim on those reasons alone. It had to examine whether a further proper reason existed, such as unavoidable circumstances not attributable to the tax authority that left no time for reconsideration before the limitation period expired, and had to misread Article 81-15(3)(iii) and fail to hear the necessary evidence on that point. The Court also said that Supreme Court Decision 2023Du41659, cited by the court below, did not appear suitable for use in that context, and reversed the judgment for remand by unanimous agreement.

Distinguishing conditions

  • A case in which a special circumstance in the Framework Act on National Taxes or its Enforcement Decree excludes the advance notice or permits an assessment without the reconsideration stage.
  • A case where the assessment limitation period came near expiry through unavoidable circumstances not attributable to the tax authority, leaving no time for pre-assessment reconsideration before it expired.

Record verification notes

Set the date of the advance notice, the date of the assessment and the expiry of the assessment limitation period against each other, and check what the tax authority did during the years before the notice. Then look for what it offers as unavoidable circumstances beyond the mere running of the limitation period, since that is what it must prove, and note that Supreme Court Decision 2023Du41659 was held unsuitable for this line of reasoning.
