The primary source of revenue for the government and economy of Saudi Arabia is the hydrocarbon sector, specifically crude oil production, petroleum refining, and petrochemical exports managed largely through state-backed enterprises like Saudi Aramco. However, under the strategic economic blueprint of Vision 2030, the Kingdom has experienced substantial growth in non-oil revenues, which now comprise a vital share of national income through corporate taxes, value-added taxes (VAT), tourism expansion, sovereign investments, and diversified industrial sectors.
