Taxation of corporate reorganization

How are the requirements for qualifying mergers defined in the statute?

This article outlines the consideration condition and three categories of qualified merger, examining representative statutory requirements. It is not a comprehensive eligibility checklist covering every joint-business condition.

Statutory definition

Article 2 of the Corporation Tax Act defines qualified mergers. Only mergers meeting specified conditions receive that treatment. For their place within reorganization taxation, see Overview of Reorganization Taxation.

The definition is as follows.

A merger falling under any of the following categories in which shareholders, etc. of the disappearing corporation receive no assets other than shares or equity interests in one corporation that is either the surviving corporation or its parent (a corporation in a relationship prescribed by Cabinet Order involving direct or indirect ownership of all the survivor’s issued shares, etc.), disregarding money or other assets delivered as dividends of surplus, etc. (dividends of surplus, dividends of profits, or distributions of surplus relating to shares or equity interests), consideration pursuant to appraisal rights of dissenting shareholders, and money or other assets delivered to shareholders other than the survivor where the survivor holds at least two-thirds of the disappearing corporation’s issued shares or equity interests by number or amount immediately before the merger.

In plain terms, the starting condition is that consideration consists solely of shares in the survivor or its parent. The statute then identifies three categories under “a merger falling within any of the following.” Each is examined below.

Overview

Issue Statutory rule
Meaning of qualified merger Defined in the Corporation Tax Act, on the premise that shareholders of the disappearing corporation receive no non-share assets.
Consideration condition (no cash or other non-share consideration) Only shares or equity interests in one corporation—the survivor or its parent—may be delivered.
Wholly controlled cases A wholly controlling relationship through either corporation, or another prescribed relationship, exists between disappearing corporation and survivor.
Controlled cases A controlling or other prescribed relationship must exist, and both employee and business-continuity requirements must be met.
Joint-business cases Multiple conditions prescribed by Cabinet Order must be met, with certain requirements omitted in specified circumstances.
Meaning of wholly controlling relationship Defined to include direct or indirect ownership by one person of all a corporation’s issued shares, etc.
Meaning of controlling relationship Defined to include ownership by one person of more than fifty percent of a corporation’s issued shares, etc.

How Are Wholly Controlled Cases Prescribed?

The first category concerns a wholly controlling relationship between disappearing corporation and survivor. The statute provides:

A merger where the disappearing corporation and survivor (or, for a merger establishing a corporation, hereinafter an “incorporation-type merger,” the disappearing corporation and another disappearing corporation) have a wholly controlling relationship through either corporation, or another relationship prescribed by Cabinet Order.

Article 2 separately defines wholly controlling relationship. This category does not require employee or business continuity, only the wholly controlling or other prescribed relationship. For corporations wholly controlled by the same person, the Enforcement Order states:

The relationship between disappearing corporation and survivor where, before the merger, both are wholly controlled by the same person (for a merger without consideration, limited to the relationships listed below), and that person is expected to continue wholly controlling the survivor afterward; if a subsequent qualified merger making the survivor a disappearing corporation or a qualified share distribution making it a wholly owned subsidiary under Article 2, item 12-15-2 is expected, control need only continue from the merger until immediately before that subsequent transaction.

Thus, the wholly controlling relationship must also be expected to continue across the merger.

How Are Controlled Cases Prescribed?

The second category concerns a controlling relationship between disappearing corporation and survivor. The statute provides:

A merger where the disappearing corporation and survivor (or, for an incorporation-type merger, the disappearing corporation and another disappearing corporation) have a controlling relationship through either corporation, or another prescribed relationship, and all the following requirements are met.

The statute lists two requirements. The first concerns employees.

Approximately eighty percent or more of the disappearing corporation’s employees immediately before the merger are expected to work afterward for the survivor, a corporation wholly related to it, or, where its principal pre-merger business is expected to pass through a subsequent qualified merger, that subsequent survivor or a corporation wholly related to it.

The second concerns business continuity.

The disappearing corporation’s principal pre-merger business is expected to continue afterward in the survivor, a corporation wholly related to it, or, where the business is expected to pass through a subsequent qualified merger, that subsequent survivor or a corporation wholly related to it.

The employee condition specifies approximately eighty percent or more, while business continuity is expressed as an expectation of continued operation.

How Are Joint-Business Cases Prescribed?

The third category is a merger for conducting business jointly. The statute provides:

A merger prescribed by Cabinet Order for conducting business jointly between the disappearing corporation and survivor (or, for an incorporation-type merger, the disappearing corporation and another disappearing corporation).

Article 4-3 of the Enforcement Order specifies these cases. One requirement is that the parties’ businesses be related.

The disappearing business (any one of the disappearing corporation’s principal pre-merger businesses; the same applies in this paragraph) and the surviving business (any one of the survivor’s pre-merger businesses, or, for an incorporation-type merger, another disappearing corporation’s disappearing business; the same applies in the following item and item 4) must be mutually related.

Another requirement is that the disappearing business continue in the survivor after the merger.

The disappearing business, limited to one related to the surviving business, is expected to continue afterward in the survivor, a wholly related corporation, or, where it is expected to pass through a subsequent qualified merger, that subsequent survivor or a wholly related corporation.

Other requirements also apply, but not all are always necessary. Certain conditions are omitted as follows:

All the following requirements must be met, excluding item 2 where both parties (or all disappearing corporations in an incorporation-type merger) are corporations in Appended Table 2 or 3 prescribed by Ministry of Finance Order as cooperatives or similar organizations for mutual assistance among member businesses or consumers; and excluding item 5 where none of the disappearing corporations is controlled by another person immediately beforehand, or the survivor has no capital or equity contributions.

The specific provisions are listed among the statutory references.

How Is the No-Cash-or-Other-Consideration Requirement Prescribed?

All three categories require the consideration condition. The definition prohibits delivery to the disappearing corporation’s shareholders of assets other than shares or equity interests in one permitted corporation. However, dividends of surplus, etc., dissenting-shareholder appraisal consideration, and money or other assets delivered to other shareholders when the survivor owns at least two-thirds of the disappearing corporation’s issued shares, etc. immediately beforehand are expressly disregarded. For treatment where this condition is not met, see What Happens When a Merger Is Non-Qualified?.

Points that require care in practice

  • Wholly controlling and controlling relationships are both defined in Article 2, with different ownership thresholds.
  • Employee and business-continuity requirements are both framed as future expectations.
  • The joint-business category has multiple requirements under Enforcement Order Article 4-3, all of which must be met except in specified circumstances.
  • The consideration condition expressly lists disregarded assets, including dividends of surplus and appraisal-rights consideration.
  • The statute uses the term “parent of the surviving corporation.” Distinguish shares in the survivor itself from shares in that parent using the statutory wording.
  • Qualified status determines treatment of succession to assets and liabilities. Transfer and restriction of tax loss carryforwards are separate issues, addressed in Transfer of Tax Loss Carryforwards and Restrictions You can check with.
  • The provisions cited here cover only part of the qualified-merger requirements. Eligibility for a particular merger requires reading the full provisions.
