Gabon’s fiscal overhaul: Oligui Nguema sets ambitious DGI agenda

During a high-profile ceremony at the presidential palace, newly appointed Director-General of Taxes Edith Laure Mbiguidi Oyaya and her leadership team received their marching orders from President Brice Clotaire Oligui Nguema. The session underscored the administration’s commitment to placing tax mobilization at the forefront of Gabon’s national development strategy, marking a pivotal shift in public finance management.

Tax administration as a catalyst for economic transformation

President Oligui Nguema emphasized that robust fiscal performance is the linchpin for delivering on infrastructure upgrades, education expansion, healthcare improvements, and economic sovereignty. With Libreville aiming to wean itself off volatile oil revenues, broadening the tax base and enhancing collection efficiency have become non-negotiable priorities. The DGI is no longer just a revenue collector—it is being positioned as a strategic tool for budgetary oversight and macroeconomic credibility.

During closed-door discussions with the new leadership, the President underscored the dual imperatives of efficiency and integrity. Cracking down on tax evasion, digitizing procedures, and ensuring transparent treatment of taxpayers emerged as critical deliverables. The goal is to metamorphose an historically rigid tax authority into an enabling force for private sector growth and investor confidence.

Edith Laure Mbiguidi Oyaya inherits a fiscal balancing act

The appointment comes at a juncture when Gabon is navigating post-crisis fiscal tightropes, including liquidity constraints and ongoing negotiations with international lenders. The incoming DGI chief inherits an institution whose performance will determine the sustainability of public debt and the state’s investment capacity. Her success hinges not only on technical upgrades but also on securing unwavering political backing to overcome entrenched bureaucratic resistance.

The leadership team faces immediate challenges: accelerating online tax filings, tightening payment traceability, aligning extractive industry taxation with CEMAC standards, and implementing IMF-backed technical reforms. While these initiatives are not novel, their accelerated execution has become synonymous with the credibility of the President’s economic reform narrative. Cooperation with multilateral partners remains a cornerstone of the modernization drive.

Fiscal reform: the backbone of Gabon’s socioeconomic renewal

Since assuming office in mid-2023—and following his electoral validation in April 2025—President Oligui Nguema has consistently framed fiscal sovereignty as a cornerstone of his political legacy. The official discourse weaves together economic diversification, social equity, and equitable redistribution, all of which demand a more robust and equitable tax system. The blueprint prioritizes increasing contributions from high-value sectors while easing the burden on low-income households.

Yet, Gabon’s fiscal puzzle remains intricate. The economy retains a large informal segment, a narrow taxpayer base, and a lingering hydrocarbon dependency that subjects public finances to volatile global prices. Expanding the tax net will require a multi-pronged approach: incentivizing formalization, simplifying compliance pathways, and selectively enforcing stricter audits. The DGI chief must strike a delicate balance between immediate revenue gains and long-term structural reforms, all while meeting the executive’s demand for rapid, visible results.

The presidential endorsement sends a clear signal to international partners. By publicly aligning with the DGI leadership, the Head of State aims to reinforce confidence in Gabon’s commitment to fiscal discipline and governance transparency. The trajectory of non-oil revenues will be closely monitored as an early indicator of Libreville’s economic reform momentum.
