4.1 The Moment an Owner Decides to Exit
Selling a company is as much an emotional decision as a financial one, and many owners deliberate until the optimal window has passed. Triggers vary: ① children unwilling or unready to succeed, ② the owner’s health or retirement, ③ inheritance and gift taxes making family succession impractical, ④ a fair-priced exit during a strong industry cycle, and ⑤ the need for a large corporate’s or professional investor’s resources to reach the next stage of growth. What matters more than the trigger is when, and in what structure, the exit is executed.
Five Triggers for Owner Exit
No succession path
Children lack willingness or capability
Health or retirement
Owner life-cycle considerations
Tax burden
Inheritance/gift tax pressure and unavailable succession relief
Strong industry conditions
Opportunity to exit at an attractive price
Growth resources needed
Need for a strategic buyer or professional investor
The best exit often comes when enterprise value is high and the owner can still make clear decisions.
PerspectiveThe best exit is one decided proactively while enterprise value is high and the owner's judgment is intact.
4.2 Succession or Sale: What Decides It
The later succession planning starts, the fewer the options. If inheritance begins without preparation, rising share values and unmet deduction requirements push up the tax bill, scattered shareholdings slow family decisions, a shortage of tax funding forces fire sales of core assets or excessive dividends and borrowing, and an ill-defined successor role unsettles key employees and customers. Family succession deserves first consideration when there is a clear successor whose capability can be built step by step, the family agrees on long-term ownership, and there is a workable plan for the tax and its funding. Conversely, when no suitable successor exists, shareholders’ goals diverge or liquidity needs are large, growth requires outside capital and capability, or a deal opportunity can realize enterprise value, a sale or investment comes first. Succession and sale are not either/or: they form a spectrum from full succession through staged transfer, hybrid structures, minority investment and divisional sales to a strategic sale, and every scenario should be compared on the same yardsticks — enterprise value, after-tax cash flow, governance and execution risk. The tax regime, tax funding and the gift-versus-inheritance mix that follow a succession decision are covered in the next item.
Succession First vs Sale/Investment First — Criteria and the Execution Spectrum
Decision criteria
Consider family succession first
Is there a successor and a plan?
- 01A clear successor with a strong will to take over
- 02Capability can be built step by step through key roles and co-management
- 03Family agrees on long-term ownership, dividend and investment principles
- 04A workable plan for expected gift/inheritance tax and its funding (dividends, installment payment, borrowing)
Consider a sale or investment first
Is outside capital or a deal the answer?
- 01No suitable successor, or succession intent is uncertain
- 02Shareholders’ goals diverge or liquidity needs are large
- 03Growth requires outside capital and technology or market capability
- 04A deal opportunity exists to realize enterprise value (market demand, expected value)
Execution scenarios — from full succession to strategic sale
01
Full family succession
Transfer management and equity to the successor; succession tax regime, tax funding and organizational stability are key
02
Staged transfer of control
A co-management period for founder and successor to prove capability and market trust
03
Hybrid structure
Successor runs the business, family keeps part of the equity, outside investor comes in
04
Minority investment
Keep control while securing growth capital and outside expertise
05
Sale of a division or non-core assets
Focus on the core business; manage the succession burden and tax funding at once
06
Strategic sale
Transfer control to an investor with synergies and realize enterprise value
Common yardsticks — enterprise value and after-tax cash flow · governance · fairness among family · key people · timeline and execution risk
CapabilityThe comparison starts by putting four lenses in one table — family (successor intent, consensus, shareholder liquidity), company (growth, capital needs, organizational capability), deal (enterprise value, investor type, scope of sale, retained control) and after-tax outcome (tax burden, cash flow, tax funding, post-deal asset structure).
4.3 The Backbone of Succession Tax: Inheritance Deduction, Gift-Tax Relief and Tax Funding
Two regimes decide the tax burden once succession is chosen. ① The family-business inheritance deduction: at inheritance, family-business assets are deducted from the inheritance tax base, capped at KRW 30bn, 40bn or 60bn when the predecessor ran the business for 10, 20 or 30+ years (as of Sep 2026). It covers SMEs and mid-sized companies with three-year average revenue under KRW 500bn; the predecessor must have managed the business for 10+ years and held 40% (listed: 20%) as largest shareholder for 10 years, the heir must have worked in the business for 2+ years and become an officer by the filing deadline and CEO within 2 years, and industry, headcount, assets and shareholding must be maintained for 5 years afterwards. ② The gift-tax special provisions for succession: when a parent aged 60+ who has run the company for 10+ years gifts its shares during life, KRW 1bn is exempt and the rest is taxed at 10% up to KRW 12bn and 20% above (cap KRW 60bn); the recipient must become CEO within 3 years and observe 5-year post-transfer conditions, and the gift tax can be paid in installments over up to 15 years. Shares gifted under the relief are aggregated at inheritance but can then flow into the inheritance deduction if the tests are met. Under both regimes, non-business assets — real estate, loans receivable, excess cash, financial instruments — fall outside the deduction, so restructuring the asset base before succession determines the real benefit, and tax funding combines installment payment, dividends, insurance, borrowing and partial share sales to match the tax bill and cash flow. Gift and inheritance are mixed by asset type: shares and businesses expected to appreciate are gifted early at today’s value, control-critical shares are transferred in stages as the successor proves out, assets that generate dividends or rent are tied to the funding plan, and non-business or liquid assets outside the deduction are separated from the business shares and timed on their own. Requirements and caps change often, so the actual design must be re-checked against the law in force at the time of succession.
Two Pillars of Succession Tax — Inheritance Deduction vs Gift-Tax Special Provisions (as of Sep 2026)
| Item | Inheritance deduction (on death) | Gift-tax special provisions (lifetime gift) |
|---|
| When | At inheritance — family-business assets deducted from the inheritance tax base | At a lifetime gift — low flat rates on corporate shares (sole proprietors excluded) |
| Eligible company | SME, or mid-sized company with 3-year average revenue under KRW 500bn | Same (corporate shares only) |
| Transferor | 10+ years of continuous management · largest shareholder with 40% (listed: 20%) held 10+ years incl. related parties · CEO for a substantial part of the period | Aged 60+ · 10+ years of continuous management · same largest-shareholder test |
| Transferee | Aged 18+ · 2+ years in the business before inheritance · officer by the filing deadline, CEO within 2 years | Aged 18+ · in the business by the filing deadline · CEO within 3 years of the gift |
| Benefit · cap | Deduction capped at KRW 30bn / 40bn / 60bn for 10+ / 20+ / 30+ years of operation | KRW 1bn exempt, then 10% up to KRW 12bn and 20% above · cap up to KRW 60bn |
| Post-transfer conditions | 5 years — keep industry, headcount, business assets and shareholding | 5 years — keep industry, shareholding and CEO role (aggregated at inheritance; deduction may then apply) |
| Tax funding | Installment payment up to 20 years (incl. 10-year grace + 10) | Installment payment up to 15 years |
Both regimes: real estate, loans receivable, excess cash and financial instruments (non-business assets are excluded) → pre-succession asset restructuring drives the real deduction
Requirements and caps as of Sep 2026 — re-check against the law at the time of succession
CaseExample: 25 years of operation and KRW 50bn of family-business assets → the cap is KRW 40bn (as of Sep 2026), leaving KRW 10bn taxable. Once operation passes 30 years the cap rises to KRW 60bn and the whole amount fits, so timing and eligibility decide the tax bill. The specific application must be reviewed against the law and facts at the time.
4.4 Earn-out and Rollover: Two Tools for Price Gaps and Future Participation
The seller believes the business will keep growing; the buyer is reluctant to pay a premium for an unproven future. Two tools address that gap. ① Earn-out: on top of the fixed payment at closing, additional consideration is paid if agreed KPIs are met over a set period (typically 1–3 years). What matters is the KPI definition (revenue or EBITDA), consistent accounting, and how buyer interference is treated; the owner’s role during the earn-out period should be planned in advance. Vague KPIs are the seed of disputes. ② Rollover: the seller keeps a minority stake (typically 10–30%) at the sale and takes a “second bite of the apple” on post-deal value creation. If the PE buyer exits successfully in three to five years, the retained stake delivers a second payout, and to the buyer it signals confidence in the company’s future. The flip side: a retained stake is illiquid, carries limited control, and can be impaired if the buyer’s management falters — so tag-along and drag-along rights, the scope of management participation, dividends, and exit timing and method must be set out clearly in the SHA. The two point in opposite directions. An earn-out is the buyer paying more cash conditionally, so the seller’s downside is floored by the fixed payment; a rollover is the seller staying in with equity, exposed both ways. That is why the two are often combined — fixed payment + earn-out + a 10–30% retained stake.
Earn-out vs Rollover — Two Tools for Price Gaps and Future Participation
| Item | Earn-out | Rollover |
|---|
| Problem it solves | Buyer and seller disagree on today’s value | The seller wants a share of post-deal growth |
| Structure | Fixed payment at closing + additional payment if KPIs are met over an agreed period | The seller keeps a minority stake (typically 10–30%) instead of selling it |
| What the seller gets | Conditional cash — more if performance lands, only the fixed amount if not | Retained equity — a second payout on resale or IPO (second bite) |
| Horizon | Typically 1–3 years | Typically 3–5 years (the PE exit cycle) |
| Seller’s risk | Missed KPIs, definition disputes, buyer interference → no earn-out. Downside is floored by the fixed payment | Illiquid minority stake with limited control; value impaired if the buyer’s management falters. Exposed both ways |
| Key design points | KPI definition (revenue vs EBITDA), consistent accounting, treatment of buyer interference, the owner’s role during the period | Tag-along and drag-along rights, scope of management participation, dividend policy, exit timing and method |
| Governing document | SPA (consideration clauses) | SHA (shareholders’ agreement) |
| Fits when | The seller is confident in the plan but the buyer cannot verify it | The owner stays on and believes in the next leg of growth; the buyer wants to keep using the owner’s network |
They point in opposite directions — an earn-out is the buyer paying more, conditionally; a rollover is the seller staying in with equity
Often combined — fixed payment + earn-out + 10–30% retained stake
CapabilityKPIs decide an earn-out; the SHA decides a rollover. A revenue KPI can be hit by sacrificing margin, while an EBITDA KPI invites accounting-policy disputes — so the definition and calculation method must be pinned down numerically in the SPA.
4.5 After Closing: Integration (PMI) and Key-Man Continuity
Signing is not the end. Two things decide what happens after closing: integrating the organization and whether the owner stays on. ① Employment succession and integration (PMI): for owners, employee treatment matters as much as price. KPMG structures PMI into Day 1 (operating phase) and Day 100 (strategic phase). Day 1 prepares every function — sales, finance, HR, IT, admin, logistics, legal — to operate normally between SPA signing and closing; Day 100 covers function-level workshops, mid-to-long-term operating and growth models, concrete synergy plans, and a regular Steering Committee reporting cadence. ② Key-man issues and continued management: the most sensitive issue in SMB M&A is whether the owner stays on. The owner is often the key man, so buyers typically ask for 1–3 years of continued management, during which customer relationships are handed over, key employees stabilize, and operations transfer to the new management. The owner must balance “I want to rest right away” against “better terms require a commitment to stay,” with period, role, compensation and non-compete provisions clearly set out in the SPA. Both connect directly to the earn-out and rollover above — if Day 1 readiness is weak or the owner’s handover slips, the cost comes back to the seller through earn-out targets and the value of any retained stake.
① Integration — PMI Roadmap
PMI Roadmap
Day 1 (Operations) → Day 100 (Strategy)
- Day 1Prepare normal operations across sales, finance, HR, IT, general affairs, logistics, and legal
- Day 100Run function workshops and build the medium-to-long-term operating and growth model
- AfterwardRegular steering committee reporting and accelerated synergy/R&D collaboration
② Key-Man Continuity
Balancing Continued Key-Man Management
Seller desire
Rest immediately after the sale
Common ground
Typically participate in management for 1-3 years
Transfer customers, employees, and systems
Buyer desire
Ensure business continuity
SPA clauses — management participation period, role scope, compensation, and non-compete
CapabilityA management-continuation structure that fits the owner’s life plan is the final piece of a successful deal. The Day 1 checklist and the owner’s handover plan should be settled together before the SPA is signed.
4.6 Tax Optimization of Sale Proceeds
The owner’s net proceeds are the sale price minus tax. When an individual major shareholder sells unlisted shares, the rate is 22% on the first KRW 300 million of taxable gain and 27.5% above that (including local income tax). If the company qualifies as a real-estate-heavy corporation, however, the shares are treated as “other assets” and taxed at progressive rates, reaching 49.5% on gains above KRW 1 billion. Structural responses include ① selling real estate first to bring the ratio below 50%, ② switching to a business transfer, ③ separating real estate from operations via a physical or equity spin-off, and ④ staged sales (with limited effect, since a controlling shareholder is tested on cumulative transfers over three years). Cash raised through borrowing or capital increases within one year before the transfer is excluded from total assets, so short-term ratio management is not recognized.
Tax Optimization
Private Shareholder Capital-Gains Tax Rate Comparison for Unlisted Shares
- Ordinary corporationAbout 22% up to KRW 300M / about 27.5% on the excess
- Real-estate-heavy corporationBasic tax rate applies → up to 49.5% above KRW 1B
- Structural responsesPre-sale disposal · business transfer · spin-off · staged sale (3-year cumulative test)
CaseShort-term, artificial ratio management does not work. Structure the deal with tax specialists from the earliest stage.
