The appraised value drives most of the costs at transfer. The 2% transfer fee and an individual seller's withholding tax are calculated on it. Specific business tax and stamp duty are charged on whichever is higher, the appraised value or the declared sale price. The annual land and building tax uses it too.

Values are reviewed on a four-year cycle. The current round covers 2023 to 2026. A new round for 2027 to 2030 is due to take effect on 1 January 2027, and the Treasury Department has signalled increases in many areas. A transfer registered after that date may therefore cost more than an estimate made today.

Your lawyer or the land office can confirm the figure for a specific property. Condominium values are set per square metre by building and floor.

Do not agree to declare a price below the real one at the land office. It is unlawful, and it leaves you with a lower documented purchase price when you sell and repatriate the proceeds. See property taxes and buying costs and the purchase cost calculator.
