Mining tax database for Africa

Ferdi provides access to a database of tax legislation and tax systems that apply to industrial gold mines in more than twenty African countries.

In partnership with the Centre for study and research on international development (CERDI), the International Centre for Tax and Development (ICTD), the Ecole Normale Supérieure de Lyon (ENS Lyon) and the French Ministry of Europe and Foreign Affairs (MEAE), Ferdi provides access to an important database, which lists over a long period of time the main tax legal texts and details the main taxes payable by mining companies. This database has been available to the public since September 2016 and is hosted on its own website since October 2018. Updated annually, it now covers 22 French-, English- and Portuguese-speaking countries and helps improve the transparency of tax information in the extractive sector.

Over 1300 legal texts were necessary to build the database that features 3 major innovations: (i) an inventory of taxes and duties (rates, base and exemptions) payable during the prospecting phase and mining phase of a gold mining project, (ii) detailed historical information, (iii) the link between each piece of tax information and its legal source.

The tools provided make it possible to: 1) understand the characteristics of the mining taxation, 2) know the evolution of the mining taxation, 3) compare the mining taxation between African countries, 4) compare mining taxation between projects of the same country, 5) assess the sharing of the mineral resource rent between State and investors.

Update 12/08/2020

Simulations are now available for the year 2019. These simulations make it possible to estimate the mineral resource rent sharing accruing to the State, i.e. the average effective tax rate (AETR), by applying a country’s tax legislation to a mine representative of African gold mines.

Of the 22 countries in the sample, 6 experienced a change in their AETR in 2019. In Benin, Chad, Cote d’Ivoire and Mali, AETRs are increasing. While in Mauritania and Zimbabwe, AETRs are declining. However, variations in AETRs are fairly small, except in two countries where they may be particularly large. In Cote d’Ivoire, the elimination of the corporate tax exemption and the minimum tax exemption leads to an increase in the AETR of up to 8.6% for a high-grade mine and a price of gold set at $1,500/oz. In Zimbabwe, the introduction of a variable mining royalty rate based on the price of gold decreases the AETR by up to 26% for a low-grade mine and a price of gold set at $1,100/oz. Note that in Gabon, the coming into force of the new mining act did not result in a change in the AETR because mining taxation remained virtually unchanged.
