Five tax instruments changed between 2026-04-22 and 2026-05-06. Each affects foreign-investor cash flow differently. This issue isolates the foreign-investor effect, quantifies the cycle-time savings, and lays out one decision-tree per structure type (HF / PE / family office / single-name long-only). All instruments are sourced to the Korean original legal text.
| # | Instrument | Effective | Direction | Foreign Investor Effect |
|---|---|---|---|---|
| 1 | 조세특례제한법 §94 amendment | If passed: 2026-Q3 | Bullish | Holdco intercompany dividend exclusion 85%→95%. Net effect: ~10pp lower effective tax on chaebol holdco cash flow. |
| 2 | 2026 Tax Reform — FISA deferred | FISA delayed to 2028 | Bullish | 22% capital-gains overhang on resident retail removed. Foreign-treaty residents not directly affected; liquidity premium spillover. |
| 3 | NTS Interpretation 재산세과-487 | Effective 2026-06-01 | Bullish | Treaty-rate withholding (5~15%) without NTS pre-approval. Cycle time saved ~3 weeks per dividend. |
| 4 | 국세기본법 시행령 §40-2 (PE clarification) | 2026-07-01 | Mixed | Office-only investment vehicles confirmed as non-PE. Habitual-broker rule tightens for prop desks. |
| 5 | 상속세·증여세법 — Estate & Gift Tax 2026 enforcement decree adjustment | 2026-04-15 | Critical | Family-controlling-block valuation premium adjustment from 30%→20% for listed-affiliate transfers. Material to chaebol succession positioning (see §05). |
"제94조 제1항을 다음과 같이 한다. 지주회사가 자회사로부터 받은 수입배당금액 중 100분의 95(현행 100분의 85)에 해당하는 금액은 익금에 산입하지 아니한다. 다만 자회사 지분율이 30% 미만인 경우에는 100분의 70을 적용한다."
"Article 94(1) is amended as follows: Of the dividend income a holding company receives from its subsidiaries, 95 percent (currently 85 percent) shall be excluded from gross income. However, where the subsidiary stake is below 30%, 70 percent shall apply."
| Holdco | FY24 Intercompany Dividend Income (₩bn) | Current Inclusion (15%) | Post-Amendment (5%) | Effective Tax Saving (₩bn, est.) |
|---|---|---|---|---|
| SK Inc. (SK²) | 2,180 | 327 taxed | 109 taxed | ~48 |
| LG Corp. | 1,640 | 246 | 82 | ~36 |
| Samsung C&T | 1,420 | 213 | 71 | ~31 |
| GS Holdings | 980 | 147 | 49 | ~22 |
| Hanwha Corp. | 760 | 114 | 38 | ~17 |
Pass-prob 55% (FCIA APEX legislative-tracker model based on sponsor count, committee composition, and pre-election political incentives). Conditional NAV uplift estimated 4~7% across the holdco basket. Trade idea — long top-5 holdco basket, short equal-weight op-co basket, target 12-week horizon spanning vote and regulation publication.
The Financial Investment Services Act (FISA) capital-gains tax — a 22% rate on financial-investment income above ₩50m annual — has been deferred again. The pre-announced 2026 Tax Reform pushes implementation to 2028.
"금융투자소득세 시행 시기를 2025년 1월 1일에서 2027년 1월 1일로 1차 유예한 데 이어, 2028년 1월 1일까지 추가 유예한다. 자본시장 활성화 정책의 일관성을 유지하기 위한 조치이며, 향후 시장 안정화 추이를 보아 본격 시행 시기를 재검토할 예정이다."
"Following the first deferral of FISA implementation from January 1, 2025 to January 1, 2027, we are deferring further to January 1, 2028. This measure preserves the consistency of capital-market activation policy; full implementation timing will be re-examined based on market stabilization."
Foreign treaty-resident investors are not directly subject to FISA. Indirect effect through resident retail: the 22% overhang on individual investors had constrained KOSDAQ growth-name multiples. Removing it lifts the small/mid-cap liquidity premium an estimated +30~50 bps. Most material to KOSDAQ growth basket ETFs and small-cap long-only positioning.
"외국법인이 국내원천 배당소득에 대하여 조세조약상 제한세율을 적용받고자 하는 경우, 종전에는 국세청에 사전 신청하여 승인을 받아야 했으나, 본 예규 이후에는 거주지국 거주자증명서 제출만으로 원천징수의무자가 직접 제한세율을 적용할 수 있다. 다만 의심스러운 거래에 대해서는 사후 검증을 강화한다."
"Where a foreign corporation seeks to apply a treaty-reduced withholding rate to Korea-source dividend income, prior NTS pre-approval was required. Effective with this interpretation, the withholding agent may apply the reduced rate upon submission of a residence certificate alone. Post-payment audit for suspicious transactions will be strengthened."
For a US treaty-resident HF receiving a ₩60bn dividend on a 4.0% holding in a top-30 KOSPI name:
| Step | Pre-2026-06-01 (cumulative days) | Post-2026-06-01 (cumulative days) |
|---|---|---|
| Dividend ex-date | D+0 | D+0 |
| Treaty-rate pre-approval filing with NTS | D+5 | — |
| NTS review (typical) | D+18 | — |
| Approval letter | D+22 | — |
| Withholding by agent | D+24 @ 15% (treaty) | D+1 @ 15% (treaty, certificate submission) |
| Net cash to investor | D+24 | D+3 |
| Cycle time saved | — | ~21 days |
Foreign aggregate dividend payments from KOSPI listed names in 2025 totaled ~₩48 trillion. A 21-day cycle reduction at a 4% reinvestment opportunity-cost gives an aggregate ~₩115bn / year opportunity-cost savings across the foreign-investor base. For a single $1bn AUM Korea-focused fund, the per-cycle savings can run ~$3~6 million depending on portfolio yield and treaty mix.
| Activity in Korea | Pre-2026-07-01 | Post-2026-07-01 |
|---|---|---|
| Office for information gathering / market research only | Generally exempt | Confirmed exempt (codified) |
| Asset custody / purchasing only | Generally exempt | Confirmed exempt |
| Employee with delegated trade-execution authority | Ambiguous | PE risk increased ("habitual broker" rule tightens) |
| Local partner / sub-adviser arrangement | Case-by-case | Stricter contemporaneous documentation expected |
| Third-party Korean prime broker, no on-the-ground staff | Exempt | Exempt (no change) |
Foreign HFs operating Korea-focused strategies through London or Hong Kong primaries with no on-the-ground execution authority are unaffected. Foreign HFs that have hired senior research staff in Seoul should review whether those staff have de facto trade-execution authority. PE GPs running Korea-deal-sourcing teams should review the documentation framework for portfolio-monitoring engagements.
The controlling-block valuation premium under the Estate & Gift Tax Act has been adjusted from 30% to 20% for transfers of listed-affiliate stakes among controlling family members. This is technical but materially shifts the arithmetic of chaebol succession transactions.
"상속세 및 증여세법 시행령 제53조 제3항을 다음과 같이 개정한다. 최대주주 등이 보유한 상장주식의 평가에 적용되는 할증평가비율을 종전 100분의 30(중소·중견기업 등 일부 제외)에서 100분의 20으로 인하한다. 본 개정은 2026년 4월 15일 이후 상속·증여분부터 적용한다."
"Article 53(3) of the Enforcement Decree of the Inheritance Tax and Gift Tax Act is amended. The premium valuation rate applied to listed shares held by largest shareholders is reduced from 30 percent (with limited exceptions for SMEs and mid-sized firms) to 20 percent. The amendment applies to inheritances and gifts arising on or after April 15, 2026."
The 10pp reduction in the controlling-block premium materially lowers the effective inheritance-tax cost of intra-family transfers of chaebol controlling stakes. We expect an acceleration in announced succession transactions over 2026-Q3 through 2027-Q1 — particularly Hanwha (see §07 of Daily Brief #2026-019), and likely two of {SK, GS, Hyundai}.

| Structure | Most relevant 2026 changes | Recommended action this quarter |
|---|---|---|
| HF (US/UK domiciled) trading KOSPI/KOSDAQ via local prime broker | NTS-487 (treaty rate), §94 (holdco basket trade), Estate Tax (succession-driven longs/shorts) | Refresh residence certificates with all dividend-paying holdings before 2026-06-01. Build holdco basket trade for §94 vote. |
| PE GP with Korean portfolio companies | FISA deferral (exit timing), §94 (portfolio company holdco structure), Estate Tax (founder-family negotiations) | Re-time exits to capture FISA-deferral liquidity premium. Review portfolio-company holdco/op-co structuring against §94 amendment. |

| Long-only KR fund in BlackRock / Capital / Fidelity | §94 (holdco overweight), FISA (KOSDAQ growth tilt), Estate Tax (chaebol governance overlay) | Increase holdco basket weight conditional on §94 progress. Add proxy-season activism overlay for 2026-Q4 / 2027-Q1. |
