Tax
Code général des impôts with 18% VAT and mining fiscal conventions
VAT is 18% and corporate tax is 25%, but the largest taxpayers operate under mining conventions with negotiated rates, exemptions and stabilisation clauses. Guinea is outside WAEMU and keeps its own currency, the Guinean franc.
Key rules
- Jurisdiction — Direction Nationale des Impôts assesses; a specialised mining tax unit handles convention holders.
- Deadline — Corporate return: 30 April
- Deadline — VAT: by the 15th of the following month

In practice
Guinea is not a WAEMU member, so unlike its francophone neighbours it sets VAT and monetary policy independently and is not bound by the union's harmonisation directives. The revenue picture is dominated by bauxite and by the Simandou project, whose fiscal terms were renegotiated after the 2021 coup — a reminder that stabilisation clauses constrain but do not eliminate renegotiation risk.
