Tax in Gabon

Who is the tax authority?

The Direction Générale des Impôts (DGI), under the Ministère de l'Économie et des Finances, administers Gabon's tax system. The DGI enforces the Code Général des Impôts (CGI), the Code des Hydrocarbures (Loi 002/2019), and annual Loi de Finances amendments.

Gabon operates within three overlapping legal frameworks. The French-rooted civil-law tradition governs general tax procedure. The OHADA harmonized commercial code applies to business entities. CEMAC tax directives set regional minimums — especially for TVA and corporate income tax.

Gabon is also an AfCFTA member, an ECCAS member, and an OPEC member since 1975. The BEAC (Banque des États de l'Afrique Centrale) manages the XAF monetary union shared by all six CEMAC states.

What is the tax year and when are returns due?

Gabon's tax year is the calendar year (1 January to 31 December). IRPP is withheld monthly from employee wages under the pay-as-you-earn system.

TVA-registered businesses file monthly returns. Corporate provisional CIT runs through quarterly acomptes. Hydrocarbon-sector entities follow a separate schedule under the Code des Hydrocarbures.

Who is a Gabonese tax resident?

Under the Code Général des Impôts, an individual is a Gabonese tax resident if any one of three conditions applies:

• Habitual residence in Gabon (permanent home or centre of vital interests)
• Physical presence of 183 days or more in the tax year
• Gabon-source professional activity as the principal economic activity

Residents pay IRPP on worldwide income. Non-residents pay tax only on Gabon-source income. Any one test is sufficient — meeting all three is not required.

What are the personal income tax rates?

Gabon's IRPP (Impôt sur le Revenu des Personnes Physiques) uses 7 progressive brackets:

A personal allowance applies to the first XAF 1,500,000. Self-employed individuals file under a separate IRPP computation. Employees and employers both contribute to social charges on top of IRPP.

How does corporate tax work?

Gabon's IS (Impôt sur les Sociétés) splits into two distinct regimes. The rate and framework depend entirely on whether the company sits inside or outside the hydrocarbon sector.

Withholding tax on dividends paid to non-residents is 20%. Gabon has not transposed the OECD Pillar Two global minimum tax. Tax losses carry forward for 5 years under the CGI. The Nkok Special Economic Zone offers reduced IS rates — 0% for the first 10 years for qualifying investors.

Mining companies outside the petroleum sector (manganese, iron ore) face IS at 30% plus sector-specific royalties. Gabon holds Africa's largest manganese reserves, mined primarily by COMILOG, a subsidiary of Eramet.

What about TVA and indirect taxes?

TVA (Taxe sur la Valeur Ajoutée) is Gabon's VAT. The rate is set at CEMAC's harmonized standard level.

The 18% rate is consistent across all six CEMAC member states: Gabon, Cameroon, Central African Republic, Republic of Congo, Equatorial Guinea, and Chad. TVA registration becomes mandatory above the CGI threshold. TVA-registered entities file monthly returns.

Gabon also levies customs duties on imports, excise on certain goods, and sector-specific levies under the hydrocarbon and mining codes.

How are cryptoassets treated?

Gabon does not have a standalone cryptoasset tax law. The BEAC (Banque des États de l'Afrique Centrale) has issued a regional advisory under the CEMAC framework restricting cryptoasset activity across all six CEMAC member states.

OPEC membership and the oil-sector framework

Gabon joined OPEC in 1975, briefly suspended membership between 1995 and 2016, then rejoined. Oil and gas account for roughly 40% of GDP and approximately 70% of export earnings.

Manganese is Gabon's second major extractive export. COMILOG (a CEMAC-headquartered subsidiary of France's Eramet group) operates the Moanda deposit, which holds some of Africa's largest manganese reserves. Mining IS follows the 30% standard rate but is layered with royalties, customs duties on equipment imports, and export levies specific to the mining code.

Timber (Okoumé hardwood) is the third major sector. Log-export restrictions push value-added processing onshore, creating a domestic sawmill and veneer industry with its own indirect-tax complexity.

What is the treaty network?

Gabon has approximately 11 active bilateral tax treaties. France is the anchor partner — a holdover from the post-colonial relationship. The USA has no DTA with Gabon.

Gabon has not yet ratified the OECD Multilateral Instrument (MLI). The CEMAC Multilateral Tax Convention covers intra-CEMAC transactions among member states. No US-Gabon DTA exists — US investors face Gabonese domestic withholding rates with no treaty relief.

Where does Gabon sit in the CEMAC cohort?

Gabon anchors the oil-dominant slot within the CEMAC six. The wider CEMAC cohort splits into three economic postures based on dominant revenue source:

Common pitfalls and penalties

Foreign companies and cross-border investors encounter a cluster of recurring traps in Gabon:

Currency and XAF framework

Gabon uses the Central African CFA Franc (XAF), administered by the BEAC. The XAF is pegged to the euro at a fixed rate of EUR 1 = XAF 655.957.

The XAF peg to the euro means Gabon's tax base is euro-correlated in real terms. Petroleum revenues denominated in USD are converted to XAF at prevailing rates before IS and royalty computation. XAF capital controls apply — cross-border XAF transfers outside CEMAC require BEAC authorization.

When should you consult a Gabonese tax professional?

Some filings are routine through the DGI portal. Others involve enough sector-specific complexity that professional input is material:

• Your income or business crosses the IRPP 30% or 35% bracket thresholds
• Your company operates in the oil and gas sector under a Production Sharing Agreement — the standard CGI framework does not apply
• You are in the manganese or timber sectors and face annual Loi de Finances amendments to royalty rates
• You are a US entity with no treaty access to reduced withholding rates
• You are structuring an entity under OHADA and need the tax consequences mapped
• You want to qualify for the Nkok SEZ 0%-IS incentive, but need to assess Pillar Two top-up risk at home
• You received a DGI audit notice or back-tax assessment
• You are moving in or out of Gabon mid-year and need to determine your residency status
