Hong Kong Residential Stamp Duty BSD/SSD/AVD 2027 Calculator

Compute total stamp duty on a Hong Kong residential property purchase for 2026-27 — Buyer Stamp Duty (BSD) for non-HKPR, Special Stamp Duty (SSD) for resale within 24-36 months, and Ad Valorem Duty (AVD) at tier-1 (HKPR first-home) or tier-2 (HKPR second-home / corporate) scales. Following the Oct 2024 BSD and SSD cuts.

Three Stamp Duties Stacked

HK residential stamp duty has three components: (1) Ad Valorem Duty (AVD) on every transaction, with two scales — Tier 1 for HKPR first-home, Tier 2 for everyone else. (2) Buyer Stamp Duty (BSD) — historically 15% on non-HKPR, ABOLISHED in October 2024 Policy Address. (3) Special Stamp Duty (SSD) on resales within 36 months — 20% (under 6 mo), 15% (6-12 mo), 10% (12-36 mo).

BSD and SSD Cuts (October 2024)

The October 2024 Policy Address abolished BSD entirely and reduced the SSD holding period from 36 to 24 months (some commentary suggests reduced to 12 months in 2025 — verify current rules). This was part of a wider effort to revive the HK residential market after 18 months of declining transactions. Cooling measures from 2010-2016 are largely reversed; only AVD Tier 2 remains for second properties.

HKPR vs Non-HKPR After 2024 Reform

Before October 2024: non-HKPR buyer paid AVD Tier 2 + 15% BSD = effective 28-30% tax on luxury properties. After reform: only AVD Tier 2 applies, dropping total to ~4-5% for high-end properties. This has materially shifted the buyer mix back toward mainland and foreign capital. Watch for any reintroduction of BSD if prices spike from the inflow.

When SSD Applies Most

SSD targets short-term speculators. Professional flippers buying and flipping within 6 months face 20% SSD on top of AVD — making the strategy mostly unviable. Long-term owners (>36 months hold) face no SSD. The middle period (12-36 months) at 10% SSD still meaningfully penalizes quick exits. Most strategic buyers now plan minimum 24-36 month holds to avoid SSD entirely.
