SAMA operates SARIE as the wholesale RTGS system on bank business days. The workweek is Sunday through Thursday; weekend is Friday-Saturday. Quarterly Zakat declarations under the Zakat regime apply to GCC nationals at 2.5%, with foreign-owned entities paying 20% corporate income tax under the Income Tax Law. Tadawul (Saudi Stock Exchange) trades Sunday through Thursday. CMA (Capital Market Authority) listed-entity disclosures follow quarterly cycles.
