Pre-IPO Secondary & Founder Liquidity 2026 — Thai-Resident Founders & Investors

**Scenario:** founder of US/SG/HK-incorporated startup holds USD 30M in pre-IPO shares + USD 10M unvested RSUs. Plans to relocate to Bangkok in 2026 for family reasons. IPO expected 2027.

**Naive path:** relocate Jan 2026 → Thai-resident for 2026 → IPO Q3 2027 → sale of vested + newly-vested shares → all proceeds remitted to fund Bangkok property purchase → Thai PIT 5–35% on remitted gains under POR 161 = USD 7–10M tax bill.

**Structured path:** see sequenced sections below. Net difference USD 4–8M.

**RSU vesting:** vesting date = income realisation. If vesting occurs in a Thai tax-resident year, the FMV at vest is Thai-source compensation income (because services were rendered while resident) — full PIT 5–35%.

**ISO exercise:** exercise = no Thai event under § 40(1) for foreign-issuer ISO if not connected to Thai-source employment. But subsequent sale gain is § 40(4)(d) capital gain — analysed by remittance rule.

**Practical move:** accelerate vesting + exercise to Y-1 (year before Thai residency). Pay home-jurisdiction tax at lower rate; convert position to long-term capital gain status before Thai residency triggers.

**Architecture:** founder transfers vested-pre-IPO shares to wholly-owned BVI/Cayman holdco BEFORE Thai residency, at FMV (no Thai gain — not yet resident). Holdco holds shares through IPO + lock-up.

**Post-IPO secondary:** holdco sells shares; gain accrues in BVI/Cayman (zero local tax). Founder is now Thai-resident.

**Remittance analysis:** distribution from BVI/Cayman holdco to Thai-resident founder is foreign-source dividend / capital reduction. Under POR 161/162, taxable on remittance year unless LTR Wealth-Investor exempts.

**Pre-2024 grandfather:** if holdco was funded + shares transferred before 1 Jan 2024 AND shares were owned at that date, gains attributable to pre-2024 value enjoy POR 162 grandfather — permanent shield on later remittance.

**SET / MAI (Thailand):** § 42(17) Revenue Code exempts capital gains from listed-securities sales on SET/MAI for individuals. This includes Thai-resident sellers — strongest exemption in the matrix.

**SGX (Singapore):** no Singapore CGT on share sales for individual non-residents of Singapore. Thai tax: foreign-source, POR 161/162 applies on remittance. LTR can shield.

**NASDAQ / NYSE (US):** non-resident-alien shareholders not subject to US CGT on capital gains. Thai tax: foreign-source, POR 161/162 + LTR analysis.

**HKEX (Hong Kong):** no Hong Kong CGT for individuals. Thai tax: foreign-source, POR 161/162 + LTR.

**LSE (UK):** no UK CGT for non-resident individuals (subject to UK temp-non-resident anti-avoidance if returning within 5 years). Thai tax: foreign-source, POR 161/162 + LTR.

**Tender-offer scenarios:** company conducts pre-IPO tender at fixed price for vested-employee shares. For Thai-resident employee: spread between strike + tender price = compensation income § 40(1), Thai PIT.

**Mitigation:** structure tender as 'sale by employee shareholder' in a non-employment capacity, with arm's-length pricing and no clawback — preserves § 40(4)(d) capital-gain character.

**409A / 102(b)(2) Israeli / EMI UK considerations:** home-jurisdiction equity-incentive tax rules continue to apply; Thai planning must coordinate, never override.

**Standard IPO lock-up:** 180 days post-IPO for founders/insiders; 90 days for employees. During lock-up, shares are illiquid and discounted in fair-market valuation (typical 15–25% DLOM — Discount for Lack of Marketability).

**Why this matters for Thai tax:** if shares are transferred to trust/holdco DURING lock-up, the transfer value is discounted — reducing exit-tax basis on the founder side. Net benefit: USD 1.5–4M on a USD 30M position.

**Notarial requirement:** an independent valuation report (recognised methodology — DCF, comparable, recent transaction) is required by Thai Revenue + receiving trustee. We coordinate with Big-4 / boutique valuation houses (Houlihan Lokey, Stout, Duff & Phelps).

**Share-transfer agreements:** notarised at signing jurisdiction (typically Singapore/HK/US) + Apostille + Thai certified translation.

**Holdco constitutive documents:** BVI Memorandum & Articles + Registered Agent certificate of incumbency, Apostille from BVI Registrar.

**Independent valuation report:** valuer affidavit notarised + Apostille; held in Thai counsel's file for Revenue audit.

**Tender-offer acceptance / IPO subscription:** notarial witness for founder signature blocks; Apostille if filed at foreign exchange or transfer agent.
