# 事業承継 (jigyou shoukei) — Japan business-succession framework and 事業承継税制 inheritance / gift-tax deferral (法人版 / 個人版)

## Wiki route

This entry sits under [[corporate-strategy/INDEX|corporate-strategy INDEX]] and routes into [[finance/INDEX|finance INDEX]] for the deal-side overlay. It covers the **owner-transition** problem that sits behind much Japanese restructuring. Read it with [[corporate-strategy/japan-holding-company-conversion|holding-company conversion]] (a common pre-succession reorganization), [[corporate-strategy/japan-kaisha-bunkatsu-tax-regime|会社分割 tax regime]] for carving a business ahead of a handover, and [[finance/japan-mbo-and-squeeze-out-process|Japan MBO / squeeze-out process]] for the management-buyout route when no family or internal successor exists.

## TL;DR

**事業承継 (jigyou shoukei, business succession)** is the transfer of *both ownership and management* of a company from one generation (or owner) to the next. In Japan it is a first-order economic problem: a large cohort of SME founders has reached retirement age, and many firms face closure not from insolvency but from a **lack of a successor (後継者不在)**.

Three succession routes exist:

1. **親族内承継 (family-internal)** — to a child or relative.
2. **親族外承継 / 役員・従業員承継 (internal non-family)** — to a manager or employee, often via a [[finance/japan-mbo-and-squeeze-out-process|management buyout (MBO)]].
3. **M&A (third-party)** — sale to an external acquirer when no internal successor exists.

The central tax obstacle in routes 1 and 2 is that transferring **non-listed shares (非上場株式)** triggers **inheritance tax (相続税)** or **gift tax (贈与税)** on shares that are illiquid and often highly valued — the heir can owe large tax on stock that cannot easily be sold to pay it. To solve this, Japan created the **事業承継税制 (business-succession tax system)**: a regime that **defers, and ultimately can exempt**, the inheritance / gift tax on qualifying non-listed shares, anchored in the **経営承継円滑化法 (Act on Facilitation of Succession of Management of SMEs)**.

The regime has two tracks:

- **法人版事業承継税制 (corporate version)** — for shares of a non-listed company.
- **個人版事業承継税制 (individual version)** — for the business assets of a sole proprietor (個人事業者).

Each has a **一般措置 (general measure)** and a more generous **特例措置 (special measure)**.

## 1. The Succession Problem and the Three Routes

| Route | Successor | Typical structure | Key issue |
|---|---|---|---|
| 親族内承継 | Child / relative | Gift or inheritance of shares | Inheritance / gift tax on illiquid 非上場株式 |
| 親族外（役員・従業員）承継 | Manager / employee | Often [[finance/japan-mbo-and-squeeze-out-process|MBO]] (successor buys shares, often with acquisition finance) | Successor's funding + tax |
| M&A | Third-party acquirer | Share sale / 事業譲渡 / 会社分割 | Valuation, capital-gains tax to seller |

Sources: this route classification follows the SME Agency's current business-succession support map; the table is a navigation summary, not a statement that every internal succession uses an MBO or every third-party succession uses the same legal form. ^[Sources: https://www.chusho.meti.go.jp/zaimu/shoukei/business_succession_support_measures.html; https://www.chusho.meti.go.jp/pamflet/hakusyo/2025/chusho/b1_1_9.html.]

When an internal successor exists, the binding constraint is usually **tax on the share transfer**, which is exactly what the 事業承継税制 targets. When none exists, the company typically routes to **M&A** — using the divestiture mechanisms mapped in [[corporate-strategy/spinoff-decision-tree-japan|the spinoff decision tree]] or an outright sale, with acquirer funding drawn from [[finance/japan-acquisition-finance|Japan acquisition finance]].

## 2. 法人版事業承継税制 (Corporate Version)

The corporate version lets a **successor who acquires non-listed company shares by gift or inheritance defer the gift / inheritance tax** on those shares, with eventual **exemption** when the next succession occurs or on the death of the predecessor / successor, subject to ongoing conditions.

### 一般措置 vs 特例措置

| Feature | 一般措置 (general) | 特例措置 (special) |
|---|---|---|
| Deferral ratio | Gift tax: 100%; inheritance tax: 80% | Gift and inheritance tax: **100%** |
| Eligible shares | Up to two-thirds of total shares | No share-count ceiling for qualifying shares |
| Predecessors / successors | Multiple shareholders → one successor | Multiple shareholders → up to three representative successors |
| Employment requirement | Five-year average 80% employment-maintenance requirement | A shortfall does not automatically terminate deferral; the prescribed report / support process applies |
| Advance plan required | No | **Yes — 特例承継計画 must be filed** |

Sources: the comparison is from the NTA's current business-succession-tax overview and the SME Agency's official comparison of the general and special measures. It states the high-level limits only; certification, filing, continued-holding, management, and exemption conditions remain transaction-specific. ^[Sources: https://www.nta.go.jp/publication/pamph/jigyo-shokei/index.htm; https://www.chusho.meti.go.jp/zaimu/shoukei/shoukei_enkatsu_zouyo_souzoku.html; https://www.chusho.meti.go.jp/zaimu/zeisei/pamphlet/shoukei_zeisei_jirei.pdf.]

The **特例措置** is the headline regime: it can defer **100%** of the gift / inheritance tax on qualifying shares, removing the "tax on illiquid stock" trap almost entirely — provided the company keeps operating and the successor keeps the shares and management role.

### Eligibility skeleton (high level)

- Company must be a **non-listed SME (中小企業者)** under the SME Basic Act and **not an asset-management company (資産保有型 / 資産運用型会社)** in the disqualifying sense.
- The transfer must run through the **経営承継円滑化法** certification (都道府県知事の認定).
- The **特例措置** additionally requires a **特例承継計画 (special succession plan)** confirmed by the prefectural governor *before* the succession, within the statutory filing window.

### Filing-window timing (FY2026 reform)

Per the FY2026 (令和8年度) tax-reform outline, the **特例承継計画 filing deadline was extended**: for the **corporate version** to **2027-09-30 (令和9年9月30日)**. (The **individual version** plan deadline was extended further, to 2028-09-30.) Critically, the **actual succession (the gift or inheritance) must still occur by 2027-12-31 (令和9年12月31日)** to use the 特例措置 — the plan extension does **not** move the succession deadline. Because deadlines shift with each annual reform, confirm current dates against the NTA / 中小企業庁 before relying on them.

## 3. 個人版事業承継税制 (Individual Version)

The individual version is the parallel regime for **sole proprietors (個人事業者)**: instead of shares, it defers gift / inheritance tax on **specified business assets (特定事業用資産)** — land, buildings, and depreciable business assets used in the proprietor's business — when the business is handed to a successor.

- Requires an **個人事業承継計画** filed under the 経営承継円滑化法.
- Interacts with the **小規模宅地等の特例** (small-business land valuation reduction) — the two cannot generally be stacked on the same land, so route selection matters.
- The plan-filing deadline was extended (per the FY2026 reform) to **2028-09-30**.

## 4. Reorganization Often Precedes Succession

Owner-managed firms frequently **restructure first, then hand over**, because a cleaner structure makes the succession (and the tax) more manageable:

- **持株会社化 ahead of succession** — interposing a holding company can concentrate voting control in the successor, separate operating risk, and reshape the share base before the transfer. The conversion mechanics are in [[corporate-strategy/japan-holding-company-conversion|holding-company conversion]]; the HoldCo can then be the vehicle whose shares pass under the 事業承継税制.
- **会社分割 to separate keep-vs-sell businesses** — split a multi-business company so the successor inherits the core while a non-core unit is sold or wound down. The split mechanics, including automatic employee transfer, are in [[corporate-strategy/japan-kaisha-bunkatsu-tax-regime|the 会社分割 tax regime]].
- **MBO when no family successor** — a manager / employee buys the company, typically with leverage; the structure and financing sit in [[finance/japan-mbo-and-squeeze-out-process|the MBO / squeeze-out process]] and [[finance/japan-leveraged-buyout-economics|leveraged-buyout economics]].

## 5. Strategic Reading

- **The tax is the gating item for family succession**: without the 事業承継税制, an heir can face large inheritance tax on shares that throw off little cash and cannot easily be sold — a classic forced-sale or forced-borrowing trap. The 特例措置's 100% deferral is what makes orderly family succession viable for many SMEs.
- **Deferral is conditional, not free**: the deferred tax can be **clawed back** if continuation conditions break (e.g., the successor disposes of the shares, the company stops operating, or — under the general measure — employment falls below the threshold without justification). It is a long-tail commitment, not a one-time exemption.
- **"No successor" is the real driver of Japan SME M&A**: the same demographic gap that powers the succession-tax regime also feeds third-party M&A volume, linking this entry to the deal pipeline in [[finance/INDEX|finance]] and the operating-company cases in [[business/japan-listed-corp-strategic-restructuring-matrix|the strategic-restructuring matrix]].
- **Policy finance is part of the toolkit**: public lenders and credit-guarantee bodies offer succession-specific finance for successors funding a buy-in — the institutions are catalogued in [[policy-finance/INDEX|policy-finance INDEX]].

## 6. Counterpoints and Caveats

- **Deadlines are moving targets**: the 特例措置 plan-filing and succession deadlines have been **extended repeatedly** by annual reforms; treat any specific date here as needing fresh confirmation against NTA / 中小企業庁 sources.
- **Disqualification risk**: asset-holding / asset-management companies are designed out of the regime; structures that look like passive investment vehicles may not qualify.
- **Continuation burden**: the regime presumes genuine ongoing operation and retained management — it is unsuited to a successor who plans a near-term sale.
- **Not a substitute for valuation discipline**: deferring tax does not fix an over-concentrated or poorly governed cap table; pairing succession with a [[corporate-strategy/japan-holding-company-conversion|HoldCo conversion]] or partial restructuring is common for good reason.

> confidence: **likely**. Regime structure (法人版 / 個人版, 一般措置 / 特例措置, 100% deferral under the special measure, 経営承継円滑化法 base) is confirmed against NTA and 中小企業庁. **Deadlines move with each annual tax reform** — the FY2026-reform plan-filing extensions (corporate 2027-09-30, individual 2028-09-30; succession deadline 2027-12-31) should be re-confirmed before reliance. Specific eligibility is case-specific; consult a tax professional.
