A Hong Kong stamp duty calculator that breaks a property purchase into its three transfer-tax components: Ad Valorem Duty (AVD) on the Scale 2 bands, Buyer’s Stamp Duty (BSD) of 15% for non-permanent residents, and Special Stamp Duty (SSD) on quick resales. It shows each part and the effective rate.
How it works
AVD (Scale 2) is tiered. It is a flat HK$100 up to HK$3m, then steps up through bands (1.5%, 2.25%, 3%, 3.75%) with marginal smoothing zones between them, reaching 4.25% above about HK$21.7m. The calculator applies the band that matches your price.
total = AVD + BSD + SSD
BSD = 15% of price (non-permanent-resident / company buyers)
SSD = 20% / 15% / 10% (resale within 6 / 12 / 24 months)
BSD stacks on top of AVD for non-resident buyers. SSD only applies if you resell inside the holding period; hold longer and it falls away. The effective rate is the combined duty divided by the price.
Example and notes
An 8,000,000 HKD flat bought by a HK permanent resident with no resale: AVD is HK$300,000 (3.75% band), no BSD, no SSD — a total of HK$300,000, an effective rate of about 3.75%. Add the non-resident flag and BSD adds another HK$1,200,000.
Cooling measures have been relaxed in recent reforms, so confirm the current SSD period and any surcharges with the Inland Revenue Department. Legal fees and agency commission are excluded. All figures are calculated locally in your browser.
