Gabon's Tax Breaks Cost $690M as Debt Tops 80% of GDP

Gabon gave up 403 billion CFA francs, about US$690 million, in tax revenue to exemptions in 2024. That equals 3.2% of gross domestic product and 22% of public revenue, according to the World Bank's Gabon Public Finance Review 2026. The Bank estimated that public debt exceeded 80% of GDP in 2025.

The figures come at an awkward moment. On 14 October, the finance ministry announced a US$580 million, eight-year bond with a 9.375% coupon. Gabon relies on foreign bond buyers, and it's paying a steep price to keep them.

Where the Money Goes

Oil and mining firms received 31% of the revenue given up through tax breaks. Local breweries took 8%, and banks 6%. Exemptions intended to lower the cost of basic goods accounted for 5.8% in the report's text, though its chart lists 13% and doesn't explain the gap.

Domestic value-added tax exemptions led the list at 206.9 billion CFA francs, about US$354 million. The oil refinery claimed 41% of that relief, banks 25%, and telecommunications companies 9%. Excise relief totaled 32.6 billion CFA francs, about US$56 million, and went almost entirely to locally brewed beer. Customs exemptions cost 155.9 billion CFA francs, about US$267 million. Corporate tax relief reached 7.6 billion CFA francs, about US$13 million, with 62% benefiting the timber industry.

Rules Bent, Rules Ignored

The World Bank said tax breaks have kept growing since 2022, despite a regional ban on discretionary exemptions. It found that officials had never rigorously assessed companies' commitments in return. Some mining and oil companies offset VAT refunds owed to them against other taxes, the Bank found, although no legal provision allows it. Gabonese officials told the Bank that some double-taxation treaties may cost the country more revenue than they should.

Gabon averaged non-oil tax revenue of 10.5% of GDP between 2014 and 2024, below the level in other upper-middle-income countries. The Bank blamed tax breaks and weak compliance, not high rates. Oil supplied about 40% of public revenue and 60% of export earnings in 2024, leaving the budget exposed to swings in oil prices.

The Proposed Fix

The Bank recommended removing exemptions that may lack a legal basis, limiting stability clauses in new agreements, and creating a joint body of tax, customs, and other agencies to supervise incentives. It estimated that eliminating half of the tax breaks outside the cost-of-living programme could raise up to 1.5% of GDP over the medium term. It also proposed more progressive oil and mining tax regimes and full publication of extractive contracts. Public spending ran at about 25% of GDP in 2023 and 2024.

The Bank presented its proposals as one way to contain debt while protecting priority investment.

Government Response

The government hasn't said whether it will act. On 18 September, the Council of Ministers adopted the 2027 budget bill as part of the 2026 to 2030 national growth and development plan. By mid-October, the bill wasn't public. On 15 October, the Federation of Gabonese Enterprises, which says it has about 1,100 member companies, told the Economic, Social, Environmental and Cultural Council it hadn't received a copy. No government reply to the World Bank's recommendations was reported.

President Brice Clotaire Oligui Nguema reshuffled the government on 11 October and swore in eight new ministers on 15 October. He said each would receive a roadmap with figures and deadlines, with water, electricity, jobs, and roads at the top of the list. He seized power in the August 2023 coup that ended the Bongo family's long rule and won the April 2025 presidential election.

Transparency and Trade Stakes

The US State Department's 2026 Fiscal Transparency Report found that Gabon didn't meet minimum requirements. The public could access only limited debt information, excluding debt held by state-owned companies. The article said the United States received 64% of its manganese ore imports from Gabon between 2021 and 2024. The US Geological Survey said America has produced no manganese ore with 20% or more manganese content since 1970. NYSE-listed Vaalco Energy operates the offshore Etame Marin block with a 58.8% working interest.

The Bank's breakdown covers only taxes with available data, so the full cost may be higher.

Why This Matters:

Gabon is borrowing at 9.375% while forgoing more than a fifth of its public revenue to exemptions that, according to the World Bank, were never rigorously tested against the commitments companies made in return. For investors, the signal is mixed: generous incentives can attract capital, but unpublished contracts, unauthorized offsets, and ad hoc breaks undermine the predictable rules that capital prizes. A country with debt above 80% of GDP and a budget tied to oil prices has little room for open-ended giveaways. The Bank describes broadening the base and enforcing existing rules, rather than raising rates, as the path forward. Whether the 2027 budget follows that advice remains unknown, and Gabon's creditors and business community are still waiting to see the bill.
