Stamp duty calculator Hong Kong
Ad valorem stamp duty (AVD) is paid on the documents for buying property in Hong Kong. It depends on the price or the value, whichever is higher.
Homes and non-residential property use different scales. Enter the price to see the duty and what share of the price it is.
How it's calculated
- Up to HK$4,000,000 the duty is a fixed HK$100.
- Above that, each price band has a rate that applies to the whole price, from 1.5% up to 6.5% for homes and 4.25% for other property.
- Just above each band limit there is a marginal relief band: a fixed amount plus a share of the excess, so the duty doesn't jump.
- Any fraction of a dollar is rounded up.
An example
A $5 million flat pays 2.25% of the whole price: $112,500. A $4 million flat pays $100.
