Article 11 of the KSA Value Added Tax Law delegates the authority for establishing the procedural rules for calculating annual supplies to the Implementing Regulations. This provision mandates that 'The Regulations' are responsible for determining the specific standards and the relevant time period required to calculate the value of annual supplies a Taxable Person expects to achieve. This forward-looking calculation is fundamental for determining whether a person meets the mandatory VAT registration threshold. By delegating this function, the law allows for administrative flexibility in defining the technical criteria for turnover assessment without amending the primary legislation itself.
