Tax in Guinea
Last reviewed: · by TaxProsRated editorial
Key points
Guinea's Direction Nationale des Impots (DNI) runs the tax system. Personal income tax (IRPP) is progressive across seven brackets from 0% to 40%. Corporate tax (BIC) is 35% flat, with a reduced 15% for the mining-export sector. TVA (VAT) is 18%. Guinea has approximately 4 active double tax treaties and maintains an independent currency (GNF) outside both CFA franc zones. The country is the world's leading bauxite exporter and is developing the Simandou iron-ore megaproject. Guinea has been under a transitional government following the September 2021 military coup and is currently suspended from ECOWAS.
Who is the tax authority?
The Direction Nationale des Impots (DNI), under the Ministere du Budget, administers Guinea's tax system. The DNI operates from Conakry and covers all tax categories under the Code General des Impots (CGI).
Substantive law rests on several pillars. The CGI covers income tax, corporate tax, and indirect taxes. The Code Minier (Loi 2011-006, amended Loi 2013-053) governs the extractive sector. OHADA commercial-law harmonization applies to business entities. The Loi de Finances issues annual rate and threshold amendments.
Guinea is an AfCFTA signatory, a Mano River Union member, and was an active ECOWAS member until its suspension in 2024 following the 2021 military transition.
What is the tax year and when are returns due?
Guinea's tax year is the calendar year (1 January to 31 December). IRPP for employees is withheld monthly through payroll.
Who counts as a Guinean tax resident?
Under the CGI, an individual is a Guinean tax resident if any of three conditions applies:
- Habitual residence in Guinea (permanent home or primary centre of life)
- Physically present 183 days or more in the calendar year
- Guinea-source professional activity, even without physical presence
Residents pay tax on worldwide income. Non-residents pay tax on Guinea-source income only. The three tests are independent — meeting any one establishes residency.
What are the personal income tax rates?
Guinea's IRPP uses seven progressive brackets. Rates are applied to monthly taxable income in GNF:
| Monthly income (GNF) | Rate |
|---|---|
| 0 – 1,000,000 | 0% |
| 1,000,001 – 3,000,000 | 5% |
| 3,000,001 – 5,000,000 | 10% |
| 5,000,001 – 8,000,000 | 15% |
| 8,000,001 – 12,000,000 | 20% |
| 12,000,001 – 20,000,000 | 30% |
| Over 20,000,000 | 40% |
How does corporate tax work?
Guinea's corporate income tax is called the Benefice Industriel et Commercial (BIC). The standard rate is 35% for resident companies.
Applies to most resident commercial and industrial companies. Set under the Code General des Impots and adjusted by annual Loi de Finances.
Reduced rate for qualifying mining-export operations under the Code Minier (Loi 2011-006, amended Loi 2013-053). Royalties and surface fees stack on top.
Withholding tax on dividends paid to non-residents is 10%. Pillar Two global minimum tax has not been transposed. Tax losses carry forward for 5 years. The petroleum sector operates under a separate fiscal framework with production-sharing agreements.
What about TVA and other indirect taxes?
TVA (Taxe sur la Valeur Ajoutee) is Guinea's VAT. The standard rate is 18% under the Code General des Impots.
| Rate | Applies to |
|---|---|
| 18% | Standard rate — most goods and services |
| 0% | Exports (zero-rated, not exempt) |
Excise duties apply to tobacco, alcohol, and fuel. Customs duties apply to imports under the ECOWAS Common External Tariff framework. TVA-registered businesses file monthly returns. The registration threshold is set by the Loi de Finances and adjusted periodically.
What is the currency framework?
Guinea uses the Guinean Franc (GNF), managed under a float regime by the Banque Centrale de la Republique de Guinee (BCRG).
Guinea declined entry into the Franc Zone at independence from France in 1960. The GNF has operated independently ever since. Cross-border tax flows require GNF conversion — a source of volatility for international entities operating in Guinea.
Bauxite and the Simandou iron-ore project
Guinea is the world's largest bauxite exporter and holds the world's largest known bauxite reserves. Bauxite exports are the dominant foreign-exchange earner and the primary lens through which international investors engage with Guinean tax law.
Bauxite #1 exporter + Simandou iron-ore megaproject
Guinea exports more bauxite than any other country. The Simandou deposit in the Fouta Djallon highlands is the world's largest untapped high-grade iron-ore resource. Both sectors operate under Code Minier frameworks with royalties, surface fees, and a reduced 15% BIC rate that stack in complex ways for international mining groups.
The Simandou project involves multiple international consortia and has bilateral investment-framework implications for China, Australia, and several European states. Tax practitioners working with mining clients in Guinea must navigate the CGI, Code Minier, production-sharing provisions, and any bilateral investment treaties simultaneously.
How are cryptoassets taxed?
Guinea has no dedicated cryptoasset tax law. The BCRG has issued cautionary advisories treating cryptoassets as restricted instruments. Where declared, gains fall under existing income-tax categories.
The Banque Centrale de la Republique de Guinee treats cryptoassets as outside the formal monetary system. BCRG advisories caution that crypto transactions carry no central-bank protection. No specific tax-reporting form exists — declared gains are assessed under general income-tax categories by the DNI.
Three Guineas — do not confuse them
Three entirely separate countries share the word "Guinea" in their name. Getting the wrong one is a common research error.
Guinea-Conakry. Francophone. Capital: Conakry. Currency: GNF (independent). Not in UEMOA or CEMAC. World #1 bauxite exporter. 2021 coup, transitional government.
Lusophone (Portuguese colonial). Capital: Bissau. Currency: XOF (UEMOA member). Separate small country — different tax law, different authority.
Hispanophone (Spanish colonial). Capital: Malabo. Currency: XAF (CEMAC member). OPEC member, oil-dominant economy. Completely separate tax framework.
2021 coup and ECOWAS suspension
On 5 September 2021, military forces led by Mamady Doumbouya seized power in Conakry. The transitional government extended its timeline for democratic transition into 2026. ECOWAS suspended Guinea in 2024 in response to the delayed transition.
Guinea remains under a transitional military-led government as of mid-2026. ECOWAS suspended Guinea in 2024, limiting regional trade-agreement access. Tax administration continues under the DNI, but Loi de Finances amendments and regulatory updates require closer monitoring than in peer francophone jurisdictions with stable civilian governments. International investors should track ECOWAS reinstatement timelines alongside standard tax-compliance calendars.
What is the treaty network?
Guinea has approximately 4 active bilateral tax treaties. The network is one of the smallest in West Africa. There is no US-GN double tax treaty.
Guinea has not ratified the OECD Multilateral Instrument (MLI). MLI modifications do not apply to the existing four treaties. The standard statute of limitations is 5 years; extended for fraud and for mining-sector matters.
Where does Guinea sit in the West African francophone cohort?
Guinea occupies a distinctive position in the West African tax landscape. It is francophone but not UEMOA — the only major francophone West African country that kept its own currency after independence.
Common pitfalls for foreign operators
International companies and individuals regularly hit the same traps when engaging with Guinean tax law:
GN (Republic of Guinea), GW (Guinea-Bissau), and GQ (Equatorial Guinea) are three separate countries with separate tax authorities, currencies, and legal systems. Confirm the ISO code before any filing.
Guinea uses the Guinean Franc (GNF), not the CFA franc. Neighbouring Senegal and Ivory Coast use XOF; Cameroon uses XAF. Cross-border payments require GNF conversion, adding FX exposure.
The 15% reduced BIC rate for mining-export operators does not eliminate royalties or surface fees. The total fiscal load from royalties, surface fees, and reduced BIC can exceed a standard-sector company's 35% BIC alone.
Simandou iron-ore development involves bilateral investment frameworks and project-specific fiscal protocols. First-year investors should verify whether the Code Minier, special investment agreements, or project-specific protocols take precedence for their entity.
Guinea's ECOWAS suspension limits access to certain regional trade facilitation mechanisms. The practical customs and cross-border-payment implications evolve as negotiations progress. Monitor official ECOWAS communiques alongside tax compliance calendars.
Only ~4 active DTAs — France, Switzerland, UAE, Morocco. There is no US-GN treaty. Non-treaty investors face the full 10% dividend withholding and no treaty-rate reduction on other income types.
Guinea is an OHADA member. OHADA harmonized commercial law governs company formation, accounting standards, and insolvency. Local tax filings must align with OHADA accounting — a different framework from IFRS or US GAAP.
When should you call a Guinean tax pro?
Some situations warrant specialist help in Guinea:

- Your entity has cross-border income and no DTA covers your home country
- You received a DNI audit notice, reassessment, or back-tax query
- You are establishing a company under OHADA rules and need tax-accounting alignment
