RPGT is a tax on gains made from the disposal of real property in Malaysia. It is levied on the difference between the disposal price and the acquisition price of the property. The tax rate is a fixed 5% for disposals made within 5 years of purchase, with no tax for disposals after 5 years. Exemptions are available for individuals' primary residences and for certain transactions like transfers between spouses. RPGT is administered by the Inland Revenue Board and applies to both residents and non-residents of Malaysia.
