The Holding Company as Structure: Separating the Function of Earning from the Function of Holding
2026-06-22
"I already have an operating company — why would I set up another?" Owners whose businesses have found their footing ask us this repeatedly. The answer lies in the separation of functions. The operating company is a vessel for earning; the holding company is a vessel for holding. House both functions in the same entity, and the risks of the business flow straight through to the assets. Separating the two is the starting point of the holding-company design.
The Skeleton of a Two-Tier Structure
The structure itself is simple. A holding company sits at the top, with family members as shareholders. Beneath it hang the operating companies — trading, IT, real-estate leasing, and other entities that actually run the business. Financial assets and real estate may be held by the holding company, or retained by an individual and leased to it.
Three Perspectives
| Perspective | Mechanism | Structural meaning |
|---|---|---|
| ① Treatment of dividends | Corporation Tax Act Art. 23: dividends received between companies are excluded from gross revenue (in full for wholly-owned subsidiary shares; after deducting interest-equivalent amounts for affiliated-company shares; 50% for others; a set proportion for non-controlling shares) | The tax structure for moving an operating company's profits up to the holding company differs from receiving dividends as an individual |
| ② Separation of assets | The holding company and the operating company are separate legal persons | Debts and risks borne by the operating company do not, in principle, reach the assets of the separate holding company directly |
| ③ A vessel for succession | The operating company is held indirectly through shares in the holding company | What passes to the next generation can be shifted from operating-company shares to holding-company shares |
On dividends, Article 23 of the Corporation Tax Act provides for the exclusion of inter-company dividends from gross revenue. The scope of exclusion varies by shareholding category; for wholly-owned subsidiary shares, the full amount is excluded. This differs structurally from the taxation of dividends received directly by an individual.
The separation of assets follows from the entities being distinct legal persons. Even if the operating company faces litigation, debt, or insolvency, the assets held by the holding company — a separate entity — are not, in principle, directly affected.
Points to Note on Transfers: "Book-Value Transfer" vs. "Undervalued Transfer"
When a holding company is newly established and an individual's operating-company shares are moved into it, the tax consequences vary sharply with the method of transfer.
- Book-value transfer via qualified reorganization: Article 62-9 (qualified share transfer) and Article 62-4 (qualified contribution in kind) of the Corporation Tax Act provide that, where certain requirements are met, the transfer is treated at book value. Meeting those requirements means no capital-gains tax arises at the time of transfer.
- The annual gift deduction: One means of moving shares to family is the annual (calendar-year) gift. Article 70-2-4 of the Act on Special Measures Concerning Taxation deducts ¥1.1 million per year from the gift-tax base (a special provision overriding the ¥600,000 of Article 21-5 of the Inheritance Tax Act).
- The pitfall of undervalued transfer: A transfer at a price markedly below market value may fall within Article 59 of the Income Tax Act (deemed transfer) or Article 7 of the Inheritance Tax Act (transfer at a markedly low price treated as a deemed gift). Transferring "cheaply" does not necessarily avoid the tax burden.
Note, too, that unlisted shares are valued by methods distinct from those for listed shares, and depending on the method a value diverging from market price may be arrived at. The valuation of shares as a succession asset is a point requiring specialist examination.
Denial Risk and the Demand for Substance
A holding company is not enough merely by existing. Article 64 of the Inheritance Tax Act provides that, where an act or calculation of a family-controlled company is found to unreasonably reduce the burden of inheritance or gift tax, the tax office may compute the taxable amount irrespective of that act or calculation. The key point: it is not the existence of the company that is denied, but acts carried out through it that are found to unreasonably reduce the tax burden.
The holding company therefore requires substance: holding shareholder meetings, managing subsidiary performance, making asset-management decisions — accompanied by minutes, reports, and actual acts of management.
Treat It as a Structural Question
Which vessel takes the function of earning, which takes holding, and which takes succession. The holding company is one option for that design. Mapping the location of assets, the risks of the business, and the policy for succession to the next generation onto a single structural diagram — then building on it with the qualified-reorganization requirements, substance, and the denial rules in view — is the starting point.
