Frequently asked questions
How much income tax will I pay as an expat working in Gabon?
Gabon uses a progressive income tax system (IRPP) with 8 brackets ranging from 0% to 35%, depending on your annual income. The first XAF 1,500,000 is tax-free, and rates increase as your income rises; for example, income between XAF 1,500,001 and XAF 1,920,000 is taxed at 5%, while income above XAF 11,000,001 is taxed at 35%. You'll also get a 20% allowance deducted from your taxable income before calculating the tax owed.
What are the social security contributions I need to pay in Gabon?
As an employee in Gabon, you contribute to two main social funds: CNSS (National Social Security Fund) at 2.5% of your gross income, capped at XAF 450,000 annually, and CNAMGS (National Disease Insurance and Social Guarantee Fund) at 2% of your gross income, capped at XAF 360,000 annually. Both contributions are deductible from your taxable income and help fund healthcare and social security benefits.
Do I pay extra tax on high salaries in Gabon?
Yes, if your annual salary exceeds XAF 1,800,000 (approximately XAF 150,000 per month), you'll pay an additional 5% complementary tax called TCTS on the amount above that threshold. This surcharge applies on top of your regular income tax and social contributions.
How does the business expense deduction work in Gabon?
Gabon allows a standard 20% business expense deduction on your taxable income, but this deduction is capped at a maximum of XAF 10,000,000 annually. The deduction is applied after social contributions and the TCTS surcharge are calculated, helping to reduce your overall tax burden.
What's my effective tax rate if I earn XAF 3,000,000 per year in Gabon?
For an annual income of XAF 3,000,000, you'd fall into the 15% bracket after the 20% allowance is applied. You'd also pay 4.5% in social contributions (2.5% CNSS + 2% CNAMGS) and potentially the 5% TCTS surcharge since your income exceeds XAF 1,800,000. Your total tax and contribution burden would be approximately 24.5% before the business expense deduction is applied.
