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 breaks 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. Public debt is estimated at more than 80% of GDP in 2025.

Households weren't the biggest beneficiaries. Oil and mining firms received 31% of the revenue the state forwent, local breweries took 8% and banks 6%. In the report's text, exemptions intended to cut the cost of basic goods accounted for 5.8%; its chart, though, puts them at 13% and doesn't explain the gap.

Who Gets the Relief

Domestic value-added tax exemptions topped the list at 206.9 billion CFA francs, about US$354 million. Of that sum, 41% went to the oil refinery, 25% to banks and 9% to telecommunications companies. 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. Oil and mining received more than a quarter, while 15% went to the cost-of-living programme. Corporate tax relief came to 7.6 billion CFA francs, about US$13 million, with 62% going to the timber industry.

The World Bank said the breaks have kept growing since 2022, despite a regional ban on discretionary exemptions. It said officials never rigorously assessed the commitments companies made in return. The breakdown covers only taxes for which data were available, so the true cost may be higher.

Gaps in Oversight

The Bank found that some mining and oil companies offset VAT refunds owed to them against other taxes, even though no legal provision allows it. Gabonese government officials told the Bank that some double-taxation treaties may cost the country more revenue than they should. Some large producers pay far less tax per unit of oil than others, the Bank said. It suggested more progressive oil and mining tax regimes and full publication of extractive contracts.

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

The recommendations are concrete: remove exemptions that may lack a legal basis, limit stability clauses in new agreements, and create a joint body of tax, customs and other agencies to supervise incentives. The Bank 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 presented the proposals as one way to contain debt while protecting priority investment.

Budget Secrecy and Borrowing

The Council of Ministers adopted the 2027 budget bill on 18 September, as part of the 2026 to 2030 national growth and development plan. On 15 October, the Federation of Gabonese Enterprises (FEG), which says it has about 1,100 member companies, told the Economic, Social, Environmental and Cultural Council it hadn't received a copy. The bill wasn't public by mid-October, so it's unclear whether it would reduce any exemptions. No government response to the World Bank's recommendations was reported.

Meanwhile, the finance ministry announced a US$580 million, eight-year bond with a 9.375% coupon on 14 October. The US State Department's 2026 Fiscal Transparency Report found that Gabon did not meet minimum requirements: only limited debt information was public, and state-owned company debt was excluded.

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

Gabon's resources matter abroad too. The United States received 64% of its manganese ore imports from Gabon between 2021 and 2024. The US Geological Survey said the United States 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.

Why This Matters: Every franc the state gives up in untested tax breaks is a franc unavailable for the water, electricity, jobs and roads the president has named as priorities. Debt sits above 80% of GDP, and a new bond carries a 9.375% coupon; the cost of leaving revenue uncollected falls on a public that depends on state services. The World Bank's findings point to a transparency problem as much as a fiscal one: exemptions with no legal basis, commitments nobody checked, and a budget bill business groups say they haven't seen. Whether the government acts on the recommendations and opens contracts and the budget to scrutiny will show if the gains from Gabon's oil and manganese reach the people who live there.
