Tax base of VAT is the total value received or receivable from the supply of goods or services. Value means money, property, consideration, service fees, or any other benefits which is ascertainable in terms of money. Tax base will also include any Excise tax arises in connection with such supply. However, tax base is exclusive of the value added tax itself and does not include any discounts or allowances, but only if discounts or allowances are clearly shown in the tax invoices.
