Guinea Personal Income Tax Guide 2026

Overview — Direction Générale des Impôts (DGI)

The Direction Générale des Impôts (DGI) administers all domestic tax collection in Guinea, including personal income tax, corporate tax, VAT (TVA), and other levies. Tax residents are taxed on worldwide income; non-residents are taxed only on Guinea-source income. Residency is determined by physical presence of 183 days or more in a calendar year, or having a permanent home in Guinea. Employees have tax withheld at source under the PAYE (retenue à la source) system. Self-employed individuals and business owners file annual returns directly with DGI. The currency is the Guinean Franc (GNF). Note that GNF is a high-denomination currency with approximately 1 USD ≈ 8,500 GNF.

IIT Tax Brackets 2026 — Annual Rates

Guinea uses a progressive annual bracket system with 4 bands and a top marginal rate of 40%. For 2026, the annual IIT brackets are:

• 0% — on annual income up to GNF 10,000,000 (tax-free threshold)
• 20% — on the next GNF 40,000,000 (GNF 10,000,001–50,000,000)
• 30% — on the next GNF 50,000,000 (GNF 50,000,001–100,000,000)
• 40% — on annual income above GNF 100,000,000

Effective tax rates are relatively low due to the GNF 10,000,000 tax-free threshold. A taxpayer earning GNF 60,000,000 per year pays approximately GNF 8,000,000 in IIT — an effective rate of ~13.3%. The top 40% rate applies only to income exceeding GNF 100,000,000, which represents a small proportion of taxpayers.

PAYE Withholding

Employers must register for PAYE with DGI and deduct tax monthly from employee salaries. The employer calculates monthly tax on gross salary, applies the annualised progressive rates, deducts CNSS employee contribution (6%), and remits the net tax to DGI by the 15th of the following month. Employers file monthly PAYE returns via DGI's online portal or in person. Employees receive annual tax summaries for their records. Failure to remit PAYE attracts penalties including fines and interest on overdue amounts. The PAYE system is designed to collect tax efficiently at source, reducing the compliance burden on individual employees.

Self-Employed Individuals

Self-employed individuals and sole proprietors are taxed under the same progressive IIT rates as employees, but must file self-assessment returns. Estimated tax is payable in quarterly instalments. The annual return must be filed by 30 April of the following year. Self-employed individuals can deduct allowable business expenses (rent, utilities, raw materials, salaries) to arrive at taxable profit. Proper books of account must be maintained. Guinea applies a minimum tax for certain businesses based on turnover where the taxpayer is unable to demonstrate their actual profit.

FAQs

Do I need to file a return if I pay PAYE through my employer?

Yes, all resident individuals must file an annual income tax return with DGI by 30 April, even if all tax was withheld at source. The process is simplified for PAYE-only employees but filing is mandatory.

Is overtime pay taxable?

Yes, all remuneration including basic salary, overtime, bonuses, commissions, and allowances are taxable as employment income. Certain specified benefits and allowances may be exempt under the tax code.

What is the GNF exchange rate impact on tax?

GNF is a high-denomination currency (1 USD ≈ 8,500 GNF). The tax brackets are set in GNF and are not formally indexed for inflation, meaning that as the currency depreciates, more taxpayers may be pushed into higher brackets over time.
