Guinea Corporate Tax Guide 2026

Guinea's corporate income tax (Impôt sur les Sociétés — IS) rate is 35% for standard companies, with reduced rates of 25% for industrial enterprises and 10% for agricultural activities. The tax is administered by the Direction Générale des Impôts (DGI) under the General Tax Code. The tax year is the calendar year, and companies must file annual returns by 30 April of the following year.

Overview — Corporate Tax in Guinea

Corporate tax in Guinea is governed by the General Tax Code (Code Général des Impôts) and administered by the Direction Générale des Impôts (DGI). A company is tax resident if it is incorporated under Guinean law or if its place of effective management is in Guinea. Resident companies are taxed on worldwide income; non-resident companies with a permanent establishment are taxed on Guinea-source income only. Companies must register for tax with DGI and obtain a Taxpayer Identification Number (NIF). The tax year aligns with the calendar year. Annual returns must be filed by 30 April following the end of the tax year.

Standard Corporate Tax Rate — 35%

The standard CIT rate for resident companies in Guinea is 35% of chargeable profits. Non-resident companies with a permanent establishment in Guinea are also taxed at 35% on Guinea-source income. Taxable profit is computed as gross revenue less allowable deductions including operating expenses, depreciation, interest costs (subject to thin capitalisation rules), and losses carried forward. Losses may be carried forward for a limited number of years. Capital gains are generally included in ordinary income and taxed at the standard corporate rate.

Reduced Rates — Industrial Enterprises — 25%

Industrial enterprises benefit from a reduced CIT rate of 25%, compared to the standard 35%. This incentive is designed to promote manufacturing and industrial development in Guinea. To qualify, the enterprise must be engaged in qualifying industrial activities including manufacturing, processing, assembly, and similar operations. The reduced rate may be subject to conditions regarding minimum investment, local content, and employment creation. Industrial enterprises may also benefit from additional incentives such as customs duty exemptions on imported machinery and equipment.

Agricultural Activities — 10%

Companies engaged in agricultural activities benefit from a reduced CIT rate of 10%. This favourable rate applies to qualifying agricultural activities including crop production, livestock farming, forestry, and fishing. The reduced rate is part of Guinea's strategy to promote food security and rural development. Agricultural enterprises may also benefit from additional incentives including exemption from certain taxes, reduced customs duties on agricultural inputs, and accelerated depreciation for agricultural assets. To qualify, the company must derive a minimum percentage of its income from qualifying agricultural activities.

Capital Allowances (Depreciation)

Guinea uses a depreciation system for tax purposes. Rates vary by asset category:

  • Buildings — 5% per annum (straight-line)
  • Plant & machinery — 10–20% per annum (declining balance)
  • Motor vehicles — 20% per annum (declining balance)
  • Computers & office equipment — 25% per annum (declining balance)
  • Intangible assets — amortised over useful life

FAQs

What is the penalty for late filing of corporate tax returns?

Late filing attracts penalties under the General Tax Code including a percentage of the tax due plus monthly interest. More severe penalties apply for failure to file after DGI notices or for tax evasion.

Can foreign companies claim treaty relief?

Guinea has a limited network of double tax treaties. Treaty relief may reduce withholding tax rates on dividends, interest, and royalties paid to non-residents. The most significant treaty partner is France, reflecting historical ties.

Is there a minimum tax for loss-making companies?

Yes, Guinea imposes a minimum tax (Impôt Minimum Forfaitaire — IMF) based on turnover for companies that are loss-making or whose tax liability falls below a certain threshold. The minimum tax is creditable against future CIT liabilities.
