The main taxes in Thailand on property are:
1. Income Tax or Withholding Tax
This fee – generally from 1% to 3% on the value of the property – is normally paid by the seller. It is calculated with a complex formula including the value of the property, how long it has been owned and personal tax rate.
2. Transfer fee
The Thailand Land Department charges 2% of the assessed value of all transfers of land and property.
This fee is paid on the day of the transfer of ownership, normally by the buyer.
3. Stamp Duty
A duty of 0.5% is charged by the Thailand Land Department on value or purchase price, whichever is the higher.
This tax is not charged if Specific Business Tax is applicable (see below) and is usually paid by the seller.
4. Specific Business Tax (SBT)
The seller will normally pay this 3.3% fee, which is levied on companies and on owners who have been in registered possession for less than five years.
