Check the Issues in the National Assembly Report on the 100-Billion-Won Inheritance Tax Deduction
Key Takeaway
The National Assembly Strategy and Finance Committee issued a review report on October 25, warning that raising the family business inheritance tax deduction to 100 billion won could worsen tax regressivity.
Why did the National Assembly Finance Committee express concern over tax regressivity?
In preparation for upcoming legislative reviews during the 2026 regular session, the National Assembly Strategy and Finance Committee conducted an extensive examination of the government's proposed amendments to the Inheritance and Gift Tax Act. The central point of debate involves elevating the maximum deduction cap for family business inheritance from 60 billion won to 100 billion won.
The report highlighted the primary public policy objective of inheritance taxation, which is mitigating extreme wealth concentration and promoting income redistribution. The legislative research staff observed that sharply increasing the deduction ceiling would inevitably concentrate tax relief on heirs of substantial corporate estates or individuals inheriting family business assets exceeding the current 60 billion won limit.
The committee's specialized staff cautioned that this concentration of benefits could undermine vertical equity and worsen tax regressivity, recommending rigorous legislative reconsideration during committee deliberations.
How does the proposed family business deduction structure change in detail?
The government's proposed reform seeks to support orderly succession for long-standing family firms that have preserved proprietary manufacturing techniques and operational expertise over generations. The bill pairs an expanded deduction ceiling with significantly tightened eligibility and post-succession maintenance obligations.
Under the current legal framework, fixed deduction ceilings ranging from 20 billion to 60 billion won apply based on management tenure brackets of 10, 20, or 30 years. In contrast, the revision introduces a formula that grants 2 billion won of deduction per year of executive management by the decedent. Consequently, claiming the full 100 billion won deduction requires at least 50 years of continuous active management.
Furthermore, the baseline qualification threshold triples from 10 years to 30 years of management, significantly narrowing the pool of eligible businesses. The table below compares the existing regulations, proposed revisions, and National Assembly review findings as verified on October 25, 2026.
| Category | Current Framework | Proposed Revision | National Assembly Committee Review |
|---|---|---|---|
| Maximum Deduction Cap | Up to 60 billion KRW | Up to 100 billion KRW | Concerns over benefit concentration on high-net-worth heirs |
| Deduction Calculation Formula | Tiered flat deductions by tenure bracket | 2 billion KRW per management year | Requires 50+ years of tenure to reach 100 billion KRW |
| Minimum Management Tenure | 10+ years | 30+ years | Tripled tenure requirement reduces qualifying firms |
| Business Scope Definition | Enumerated small and medium enterprise criteria | Firms holding specialized technology and know-how | Subjective wording risks administrative disputes and uncertainty |
| Post-Management Monitoring | 5 years | 10 years | Doubled monitoring period for employment and asset retention |
What equity concerns emerged regarding business definitions and eligible sectors?
Beyond the headline deduction numbers, the National Assembly review report questioned the qualitative standards used to determine qualifying enterprises. The amendment defines eligible entities as businesses possessing 'specialized technical capability and managerial know-how.'
The report noted that phrasing such as technical capability or managerial know-how remains highly subjective, creating potential interpretation disputes between tax authorities and corporate taxpayers. Without clear quantitative rubrics, business owners cannot reliably predict their tax treatment, creating substantial compliance uncertainty.
The committee also highlighted classification anomalies within the list of eligible industries. For instance, under standard industrial classifications, musical instrument wholesaling qualifies for the deduction, whereas musical instrument retailing is excluded. Conversely, other retail sectors such as men's and women's apparel retail are included. The report concluded that objective criteria and consistent justifications must be established before legislative enactment.
What issues were raised regarding shifting childbirth tax credits to direct subsidies?
In addition to inheritance tax measures, the review report assessed the government's proposal to replace income-based childbirth tax deductions with direct fiscal grants. The committee acknowledged that direct grants offer superior distributional benefits because non-taxable low-income households often cannot utilize standard tax deductions.
Direct transfers also deliver economic relief immediately following childbirth rather than waiting for annual year-end tax reconciliations.
However, the committee raised flags regarding funding durability and administrative overhead. The childbirth program is slated for funding through the youth account of the Future Response Fund rather than the general budget account. Because childbirth subsidies require steady, recurring multi-year disbursements, relying on fund revenues that fluctuate with macroeconomic and tax cycles could jeopardize long-term stability. The report also emphasized the administrative burden of processing applications, verifying qualifications, and preventing duplicate payouts.
What upcoming legislative milestones should be monitored?
The 2026 tax reform proposals will undergo formal parliamentary committee scrutiny immediately following the conclusion of annual audits in late October. Beginning in November, the Strategy and Finance Committee Tax Subcommittee will debate deduction ceilings, tax bracket thresholds, and corporate relief provisions.
Economic organizations argue that higher deduction ceilings are indispensable for protecting domestic manufacturing foundations and safeguarding employment during generational transitions. In contrast, opposition lawmakers and parliamentary research teams contend that unjustified tax relief during periods of fiscal deficit undermines public tax morale and horizontal equity.
The finalized tax compromise will face a floor vote in the National Assembly plenary session during early December alongside the 2027 national budget.
