Frequently asked questions
How much income tax do I pay in Gabon if I earn XAF 2,500,000 per year?
Gabon uses a progressive tax system with 8 brackets. On XAF 2,500,000 annual income, you would fall into the 10% bracket (XAF 1,920,001 to XAF 2,700,000), which applies a 10% rate with a XAF 171,000 deduction. After accounting for the standard 20% allowance and social contributions, your actual tax liability would be calculated on the reduced taxable amount.
What are the social contributions I need to pay as an employee in Gabon?
As an employee in Gabon, you pay two main social contributions: CNSS (National Social Security Fund) at 2.5% and CNAMGS (National Disease Insurance and Social Guarantee Fund) at 2%. Both are capped at XAF 450,000 and XAF 360,000 annually respectively, and both are deductible from your taxable income.
Is there an additional tax on high salaries in Gabon?
Yes, Gabon has a TCTS (Complementary Tax on Salaries) that applies at 5% on any salary above XAF 1,800,000 annually (approximately XAF 150,000 per month). This surcharge is calculated on top of your regular income tax and is applied before the standard business expense deduction.
What is the first income level at which I start paying income tax in Gabon?
The first income bracket in Gabon is 0% up to XAF 1,500,000 annually, meaning no income tax is owed on income below this threshold. Once you exceed XAF 1,500,001, you enter the 5% bracket and begin paying income tax.
Can I deduct business expenses from my taxable income in Gabon?
Yes, Gabon allows a standard business expense deduction of 20% of your income, though this deduction is capped at a maximum of XAF 10,000,000. This deduction is applied after social contributions and the complementary tax (TCTS) are calculated.
How does the progressive tax system work in Gabon for higher earners?
Gabon's income tax is fully progressive, with rates increasing from 0% at the lowest bracket up to 35% for income above XAF 11,000,001 annually. Each bracket has a corresponding deduction to reduce the effective tax rate, so your marginal rate is higher than your average rate.
