Gabon Tax Regime

Gabon operates a territorial-leaning corporate tax system as a member of the Central African Economic and Monetary Community (CEMAC), taxing profits derived from operations carried out in Gabon at a standard rate of 30%, with a higher 35% rate for companies operating in the oil and mining sectors, reflecting the central role hydrocarbons and manganese play in the national economy. The system layers a minimum turnover-based tax (Impôt Minimum Forfaitaire) and an absolute floor (Minimum de Perception) beneath the standard corporate income tax, ensuring a baseline contribution from companies regardless of reported profitability. Gabon's company law follows the OHADA Uniform Acts, and its tax code has been extended to capture simplified stock companies (SAS) and other forms introduced under the OHADA framework. Administration is centralised under the Directorate General of Taxes (Direction Générale des Impôts, DGI).

1.1 Sources

Primary legislation includes the General Tax Code (Code Général des Impôts), CEMAC regional tax and customs instruments, and the OHADA Uniform Act relating to the law of companies and economic interest groups, which governs corporate form and has driven extensions of the corporate tax base to newer entity types such as the SAS.

1.2 Recent developments

The General Tax Code has progressively broadened the scope of corporate income tax following the introduction of the simplified stock company (SAS) under the OHADA Uniform Act, bringing SAS entities within the standard CIT framework alongside the traditional SA and SARL forms. The optional extension of CIT treatment to certain ship-owning and property-owning arrangements where indefinitely liable shareholders are identifiable reflects continued efforts to reduce opacity in ownership structures. Gabon continues to strengthen enforcement of the Impôt Minimum Forfaitaire and Minimum de Perception floors, and has maintained a discharge levy on capital gains from indirect transfers of Gabonese company rights as part of a broader push to tax value created from Gabonese assets even where transactions are structured offshore. Regional CEMAC harmonisation initiatives continue to shape VAT and customs administration.

2.1 Rates and residence

Corporate income tax (CIT) is levied at a standard rate of 30% on profits from companies exploited in Gabon or from operations carried out in Gabon, subject to relief under applicable double tax treaties. A higher rate of 35% applies to companies operating in the oil and mining sectors, reflecting the elevated economic rents typically associated with hydrocarbon and mineral extraction. Gabon's tax base follows a broadly territorial logic — profits are taxed by reference to Gabonese-source operations rather than a strict worldwide-residence model, although companies incorporated and managed in Gabon are treated as falling within the ordinary CIT net for their Gabonese and Gabon-linked activities.

Two minimum-tax mechanisms operate as floors beneath the standard CIT liability. The Impôt Minimum Forfaitaire (IMF) is calculated as 1% of global turnover for the fiscal year, capturing financial and exceptional profits as well as ordinary trading revenue, and applies whenever it exceeds the CIT otherwise computed. The Minimum de Perception operates as the ultimate floor, requiring a minimum CIT payment of XAF 1,000,000 even where a company reports no taxable profit. Companies formally exempted from CIT, and new companies within an initial exemption window (three years for small and medium enterprises), are correspondingly exempt from both the IMF and the Minimum de Perception during that period.

2.2 Dividends and participation

Dividends distributed by Gabonese companies are subject to withholding tax, with a reduced regime applicable to qualifying parent-subsidiary holdings that mitigates double taxation within corporate groups, broadly in line with the francophone Central African approach to inter-company distributions. Portfolio and non-qualifying dividend flows are subject to the standard domestic withholding rate described in section 4. There is no broad-based participation exemption for capital gains on shareholdings of the kind found in OECD jurisdictions; instead, capital gains on business assets, including shares, are generally brought into the ordinary CIT computation, subject to specific deferral relief on qualifying reorganisations.

2.3 Income determination

CIT is assessed on profits, computed as the difference between revenues and deductible expenses and charges, encompassing all operations carried out in Gabon during the taxation period, including capital gains realised on fixed assets. Where a taxpayer cannot produce adequate supporting documentation to substantiate its declared taxable result, the tax administration may reconstitute the taxable base by applying a lump-sum discount to turnover net of taxes: 70% for companies engaged in the purchase, resale or production of goods for resale, 50% for service providers, and 40% for liberal professions and assimilated activities — effectively taxing the balance as deemed profit. This reconstitution mechanism creates a strong incentive to maintain complete and auditable accounting records.

2.4 Interest limitation

Interest paid to related parties, particularly cross-border related-party financing, is subject to arm's-length and deductibility scrutiny under general Gabonese tax principles and CEMAC-aligned practice, with thin capitalisation-style restrictions applied by the tax administration to curb excessive related-party leverage that would otherwise erode the Gabonese tax base. Interest paid to non-resident lenders is additionally subject to withholding tax as described in section 4, layering a further constraint on aggressive debt-funding structures.

2.5 Losses

Trading losses may generally be carried forward against future taxable profits for a limited number of years under the General Tax Code, consistent with regional CEMAC practice, though the Impôt Minimum Forfaitaire and Minimum de Perception floors continue to apply in loss years (subject to the new-company and SME exemption windows), meaning loss-making companies outside those exemption periods can still face a minimum cash tax cost. There is no loss carryback mechanism.

2.6 Group taxation

Gabon does not operate a comprehensive fiscal consolidation or group relief regime; each company is generally assessed on a standalone basis, and losses cannot be freely surrendered between group members. Group restructurings, intra-group transfers of assets, and OHADA-governed mergers and business combinations may nonetheless benefit from specific relief provisions where structured to preserve continuity of the underlying business, but such relief requires careful documentation and, in many cases, prior engagement with the DGI given the discretionary elements in the code's application.

2.7 Controlled foreign companies and anti-avoidance

Gabon does not operate a standalone codified CFC regime attributing the income of controlled foreign subsidiaries back to Gabonese parents in the manner of OECD/ATAD-style rules. Base protection instead relies on the territorial scope of CIT (profits taxed by reference to Gabonese operations), the discharge levy on indirect transfers of Gabonese company rights described in section 2.3-adjacent practice, general anti-abuse principles empowering the DGI to recharacterise artificial arrangements, and the enhanced non-resident withholding tax rate applicable where a foreign recipient lacks a Gabonese permanent establishment.

2.8 Transfer pricing

Related-party transactions must be conducted on arm's-length terms, and the DGI has increased scrutiny of transfer pricing in the extractive and services sectors, consistent with broader CEMAC and African Tax Administration Forum initiatives to strengthen base protection across the region. Multinational groups operating in Gabon should maintain documentation demonstrating the arm's-length nature of intra-group pricing for goods, services, financing and intangibles, benchmarked against comparable transactions, even though Gabon's statutory documentation thresholds and formal advance pricing agreement practice remain less developed than in major OECD transfer pricing jurisdictions.

2.9 Incentives

New companies benefit from an initial exemption from the Impôt Minimum Forfaitaire and Minimum de Perception, with a three-year exemption window specifically available to small and medium enterprises, easing early-stage cash tax burdens before profitability is established. Sector-specific incentives exist for priority sectors including agriculture, forestry value-addition, and special economic zones (such as the Nkok Special Economic Zone), which offer reduced tax rates, customs relief and streamlined administration for qualifying export-oriented and processing investments, forming a key plank of Gabon's economic diversification strategy away from oil dependency.

2.10 Pillar Two

Gabon has not enacted Pillar Two legislation implementing a qualified domestic minimum top-up tax, an income inclusion rule or an undertaxed profits rule. Few, if any, Gabonese-headquartered groups meet the EUR 750 million consolidated revenue threshold that triggers the OECD/G20 global minimum tax framework, so near-term exposure is largely confined to Gabonese subsidiaries of large inbound multinational groups (notably in the oil and mining sectors), which may be subject to top-up taxation at the level of their ultimate parent jurisdiction rather than in Gabon. The government continues to monitor CEMAC-wide and continental coordination on minimum taxation before considering domestic legislation.

2.11 Branch income and reorganisations

Non-resident companies operating in Gabon through a permanent establishment are subject to CIT on the income raised through that Gabonese branch, computed on the same territorial basis as a locally incorporated subsidiary, at the standard 30% rate (or 35% for oil and mining branch operations). Non-resident companies without a Gabonese permanent establishment are instead taxed by withholding at 25% on Gabon-source income (see section 4). Domestic reorganisations under OHADA company law — mergers, demergers and conversions — can in principle be carried out with a degree of continuity for tax purposes, but taxpayers should seek specific confirmation from the DGI given the more discretionary and less codified nature of Gabonese reorganisation relief compared with OECD jurisdictions.

3.1 Residence and rates

Resident individuals in Gabon are taxed on worldwide income, while non-residents are taxed on Gabon-source income only; residence is generally established by having a permanent home, principal place of abode, or centre of economic interests in Gabon. Personal income tax is levied on a progressive scale across several bands, with rates rising from an exempt or low initial bracket up to a top marginal rate in the region of 35%, applied to a family-quotient-adjusted taxable base that takes into account marital status and number of dependents, following the francophone approach shared with several other CEMAC member states.

3.2 Employment income and benefits

Employment income, including salary, allowances and the taxable value of benefits in kind (housing, company vehicles and similar perquisites), is subject to payroll withholding by the employer, remitted monthly to the tax administration. Certain statutory allowances and reimbursements of documented business expenses are excluded from the taxable base. Termination indemnities and specified retirement benefits receive partial exemption up to prescribed statutory limits, consistent with regional labour law and tax practice.

3.3 Capital gains and other income

Capital gains realised by individuals on the disposal of Gabonese business assets, real estate and shares are generally subject to tax, with the discharge levy of 20% specifically applicable to gains on transfers of social rights (parts sociales/actions) in companies whose assets are substantially comprised of, or which hold, rights in Gabonese companies — a mechanism aimed at capturing value from indirect and offshore-structured transfers of Gabonese assets. Rental and investment income earned by resident individuals is taxable at the progressive personal scale, net of allowable deductions for property-related expenses.

3.4 Inbound individuals and social contributions

Employees and employers contribute to the National Social Security Fund (Caisse Nationale de Sécurité Sociale, CNSS) covering pensions, family benefits and workplace injury insurance, at rates set by regulation and applied up to contribution ceilings; a national health insurance and social solidarity contribution (CNAMGS) also applies to fund universal health coverage. Gabon does not levy a general net wealth tax. Expatriate employees are generally taxed on Gabon-source employment income from the commencement of their local assignment, subject to relief available under an applicable double tax treaty, and employers of expatriate staff should factor in both PAYE-equivalent withholding and mandatory social contributions when budgeting assignment costs.

Gabon applies withholding tax to a range of payments made to residents and non-residents, with the treatment for non-residents lacking a Gabonese permanent establishment generally operating as a final tax. Non-resident companies without a Gabonese permanent establishment are taxed by withholding at 25% on Gabon-source income generally, a comparatively high rate reflecting Gabon's territorial approach and its reliance on withholding to secure tax on cross-border payments. Capital gains arising from the transfer of social rights in companies substantially comprised of Gabonese rights are subject to a discharge levy of 20%, collected and remitted by the Gabonese company whose rights are transferred within one month of the transfer. Gabon's treaty network is more limited than that of many OECD economies, with the CEMAC regional framework and a smaller number of bilateral treaties (including with France) providing relief in qualifying cases.

Where a non-resident company has a permanent establishment in Gabon, it is instead brought into the ordinary CIT regime on income raised through that Gabonese PE, rather than being subject to the 25% no-PE withholding rate, so correctly characterising the presence (or absence) of a Gabonese PE is a critical first step in any cross-border payment analysis. Treaty relief, where available, generally requires the recipient to substantiate residence and beneficial ownership in the treaty partner jurisdiction, and the discharge levy on indirect share transfers must be assessed even in transactions structured entirely outside Gabon if the underlying value derives substantially from Gabonese company rights.

5.1 General anti-abuse and indirect transfers

The General Tax Code empowers the DGI to look through arrangements lacking economic substance and to recharacterise transactions structured primarily to avoid Gabonese tax. The discharge levy on capital gains from the transfer of social rights in companies whose assets are mainly Gabonese rights, or which hold direct or indirect rights in a Gabonese company, operates as a targeted anti-avoidance mechanism against offshore share-transfer structures designed to extract value from Gabonese assets without triggering Gabonese tax — the Gabonese company whose rights are transferred bears responsibility for collecting and remitting the levy within one month of the transfer, shifting compliance risk onto the local entity.

5.2 Regional coordination and transparency

As a CEMAC member, Gabon participates in regional tax and customs harmonisation initiatives, and cooperates with international transparency bodies on exchange of information, though its treaty and multilateral instrument coverage remains more limited than that of larger economies. OHADA company law underpins beneficial ownership and corporate transparency to a degree, given the requirement to identify shareholders with indefinite liability for certain optional CIT extensions (ships and property-owning arrangements), reinforcing the tax administration's ability to trace ultimate economic interests in structures that might otherwise obscure ownership.

6.1 VAT

Value Added Tax applies at a standard rate of 18%, consistent with CEMAC regional VAT harmonisation guidelines, with a reduced rate applicable to specified essential goods and services and a zero rate for qualifying exports. Registration is required for businesses exceeding the statutory turnover threshold, with monthly VAT return and payment obligations for registered taxpayers. Input VAT is recoverable against output VAT for taxable business activities, subject to standard restrictions on non-business and specified categories of expenditure, and import VAT is collected at the point of customs clearance alongside applicable customs duties under the CEMAC common external tariff.

6.2 Transaction, property and other taxes

Registration duties (droits d'enregistrement) apply to specified legal acts and transfers, including transfers of immovable property and certain corporate transactions, at rates set by the General Tax Code. Payroll-related employer contributions fund the CNSS and CNAMGS social systems described in section 3.4. The oil and mining sectors are subject to sector-specific royalty and production-sharing arrangements layered on top of the standard 35% CIT rate for those sectors, reflecting production-sharing contracts negotiated with the state alongside ordinary tax law. There is no general net wealth tax or broad-based inheritance tax regime of the scale seen in some OECD jurisdictions, though registration duties can apply to gratuitous transfers.

7.1 Filing, assessment and audit

The Gabonese tax year is generally the calendar year for most taxpayers, though companies may in some cases align filings with an adopted accounting year-end subject to administrative practice. Companies file annual CIT returns with the Directorate General of Taxes (DGI), together with periodic payments reflecting the interaction between ordinary CIT liability and the IMF/Minimum de Perception floors described in section 2.1. The DGI conducts risk-based audits with increasing attention to the extractive sector, related-party transactions, and reconstitution of taxable results for taxpayers with inadequate supporting documentation (see section 2.3). Statutory limitation periods govern the period within which the DGI may raise additional assessments, subject to extension in cases of fraud.

7.2 Rulings, appeals and penalties

Taxpayers may seek clarifications and, in more significant cases, rulings from the DGI on the tax treatment of proposed transactions, though formal binding ruling practice is less codified than in mature OECD administrations. Disputes are pursued initially through administrative objection to the DGI and, where unresolved, through the Gabonese courts. Penalties and interest apply for late filing, late payment, and understatement of tax liability, including in cases where the administration reconstitutes taxable income using the lump-sum turnover-discount method described in section 2.3 due to inadequate taxpayer documentation.

Because the IMF and Minimum de Perception operate as floors beneath the ordinary CIT computation, taxpayers should calculate all three figures (standard CIT, 1% turnover-based IMF, and the XAF 1,000,000 Minimum de Perception) at each filing cycle and remit the highest, rather than assuming a loss-making year eliminates Gabonese corporate tax exposure outside the new-company exemption window.

9.1 Entity choice

The société anonyme (SA) and société à responsabilité limitée (SARL) remain the traditional vehicles for inbound investment under OHADA company law, now joined by the simplified stock company (SAS), which the General Tax Code has expressly brought within the CIT net, offering more flexible governance for joint ventures and holding structures. Branches of foreign companies are permitted and are taxed on Gabon-attributable profits at the standard rate (30%, or 35% for oil and mining), while non-resident companies without a Gabonese permanent establishment instead face the 25% withholding tax on Gabon-source income described in section 4, making the PE-versus-no-PE characterisation a first-order structuring question.

9.2 Structuring and incentives

New entrants should evaluate the three-year Impôt Minimum Forfaitaire and Minimum de Perception exemption available to small and medium enterprises, the Nkok Special Economic Zone and other sector incentives for export-oriented and processing investments, and the interaction between the standard 30% rate and the elevated 35% rate for oil and mining operations when structuring extractive-sector projects. Cross-border share transfer structures involving Gabonese company rights should be tested against the 20% discharge levy on indirect transfers, and financing structures should be benchmarked to arm's-length terms given the DGI's increasing transfer pricing and thin capitalisation scrutiny of related-party debt.

9.3 Worked effective-rate illustration

A Gabonese services subsidiary (non-oil/mining, taxed at the standard 30% rate) reports turnover of XAF 3,000,000,000, EBITDA of XAF 400,000,000, depreciation of XAF 60,000,000, and arm's-length interest expense of XAF 40,000,000 fully deductible. Taxable profit is 400,000,000 − 60,000,000 − 40,000,000 = XAF 300,000,000. Standard CIT at 30% is XAF 90,000,000. The Impôt Minimum Forfaitaire, at 1% of the XAF 3,000,000,000 turnover, is XAF 30,000,000 — lower than the standard CIT figure, so the company pays the higher of the two, i.e. the standard CIT of XAF 90,000,000 (the IMF does not apply as an addition once ordinary CIT exceeds it). The Minimum de Perception floor of XAF 1,000,000 is immaterial here since it is far below both other figures. The effective corporate tax rate on taxable profit is therefore 90,000,000 / 300,000,000 = 30.0%, equal to the headline rate because the IMF floor did not bind in this profitable scenario; in a low-margin year where 1% of turnover would exceed 30% of taxable profit, the IMF would instead determine the liability.

9.4 Compliance

Expect annual CIT filing with parallel computation of the IMF and Minimum de Perception floors, monthly VAT compliance once registered, monthly payroll withholding and social contribution remittances, and specific one-month compliance deadlines for the discharge levy on transfers of social rights in Gabonese-linked companies. Groups in the oil, mining and forestry sectors should additionally track production-sharing contract obligations and sector-specific royalty regimes that sit alongside, rather than replace, the standard corporate tax compliance calendar.
