Article 65 of the GCC Common VAT Agreement delegates authority to each individual Member State to establish the specific conditions and provisions for tax refunds. It empowers each state to create its own legal framework governing how a Taxable Person can request a refund of their net deductible tax. This provision also covers the alternative option for a Taxable Person to request that the net tax amount be carried forward to subsequent tax periods. This article ensures that while the principle of tax recovery is unified, the procedural implementation is determined by local legislation within each jurisdiction.
