Guinea aims to raise tax revenue to 15% of gross domestic product from an estimated 12.9% as it prepares its initial 2027 budget, the head of the domestic revenue mobilization mission MAMRI, Mohamed Lamine Doumbouya, told Prime Minister Amadou Oury Bah on November 4, Ecofinance Guinée reported. He said the ratio should rise gradually and 'as far as possible'.
Analysis: Closing the 2.1-point gap would bring in about 8.7tn GNF (€877mn) more a year at 2025 output, by our calculation from statistics agency INS data. That is slightly more than the 8tn GNF (€812mn) the state drew from mining in 2025, the central bank BCRG said. The starting point is unclear, however: by our calculation from BCRG and INS figures, all 2025 revenue and grants came to 11.4% of GDP, below the 12.9% tax ratio cited. Companies should watch for new tax measures in the 2027 draft budget, which has not yet been sent to parliament.
