Article 36 of the KSA Value Added Tax Law establishes the legal requirement for the retention of tax-related documentation. The Article does not specify the exact duration for which records must be kept. Instead, it mandates that the Implementing Regulations will determine the specific time period required for retaining Tax Invoices, books, records, and other accounting documents. This provision delegates the authority for setting detailed compliance rules on record-keeping to the relevant regulatory body, ensuring that taxable persons must refer to the Regulations for the precise statutory retention periods applicable to their business operations.
