The VAT treatment of real estate will depend on whether it is a commercial or residential property.
Supplies (including sales or leases) of commercial properties will be taxable at the standard VAT rate (i.e 5%).
On the other hand, supplies of residential properties will generally be exempt from VAT. This will ensure that VAT would not constitute an irrecoverable cost to persons who buy their own properties. In order to ensure that real estate developers can recover VAT on the construction of residential properties, the first supply of residential properties within 3 years from their completion will be zero-rated.
