Taxation of mining industries

Understanding the sharing of the mineral resource rent between States and investors


The Ferdi provides the first legal and tax database that lists the tax regime applicable to industrial gold mines in 21 African producing countries since the 1980s and a simulation tool for sharing the mineral resource rent between State and investors.

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.

Accessing an innovative database

Improving the mobilisation of domestic resources is a hight priority for African countries. The heavy dependence of these countries on the extractives industries implies understanding the mechanisms and consequences of the mining tax Regim applied in Africa on the development of the extractive industry as well as the public revenu collection.

Although several international institutions, non-governmental organisations and universities publish on this issue, data on mining tax Regim in Africa remains difficult to access. Thus, improving the transparency of information in the African mining sector has become a priority for the international community.

The database provided has three major innovations:

  • An inventory of the 12 main taxes and duties (rates, bases, exemptions) that are due during the prospecting and mining phases of a mining project;
  • An unprecedented historical depth;
  • The link between each piece of tax information and its legal source.

The database now concerns 14 French-speaking countries and 7 English-speaking countries: Benin, Burkina Faso, Cameroon, Chad, Republic of the Congo, Democratic Republic of the Congo, Cote d’Ivoire, Gabon, Ghana, Guinea, Kenya, Madagascar, Mali, Mauritania, Niger, Nigeria, Senegal, Sierra Leone, South Africa, Tanzania and Zimbabwe.

The database currently focuses on gold, that is exploited in 34 of the 54 African countries, making it the second larger producer in the world.

The information provided here is intended for researchers, States and public administrations, international institutions and all national and international stakeholders. The objective is to contribute to the improvement of public policies and the information of companies, with a goal of international development.

Full access to the legal and tax data of the website requires a subscription. The subscription is free for individuals or institutions that commit to make no commercial use. On the other hand, financial participation is requested from individuals or companies wishing to use the data for commercial purposes.

Comparing the share of the mineral resource rent that goes to the State

States have to arbitrate between the will to attract foreign investors and the need to increase public revenues. Applied to the economic data of a representative mine and associated with a cash flow model, this database offers the means for researchers and analysts to summarize the tax burden that should apply to mining companies in the African countries according to the legislation. The indicator calculated is the average effective tax rate (AETR), that represents the share of the mineral resource rent captured by the State on a mining project.


A very high AETR, near 100% or higher, should not be too strictly interpreted. It does not mean that the State manages to collect all of the rent; rather it means that the tax burden makes the mine economically unviable. This illustrates the significant impact of the tax system and the gold price on the profitability of a mining project.

Studying the evolution of the share of the mineral resource rent that goes to the State

The unprecedented historical depth of this database makes it possible to follow the evolution of the average effective tax rates since the 1990s in 21 African countries. This history shows the impact of the successive tax reforms decided by African States (rates, bases, calculation rules) to try to adapt to a context of instability of world prices.

Update 2019 : Cameroon, Chad and Ghana


Updated tax data for 2019 are now available for Cameroon, Chad and Ghana.
In Cameroon, the Finance Act 2019 did not change mining taxation (Act No. 2018/022 of 11 December 2018). Similarly, in Ghana, there were no changes to mining taxation in 2019. In Chad, the minimum tax was raised from 1 to 2 million CFA francs for large companies (Act No. 037/PR/2018 of 31 December 2018).

Chadian minimum tax: increase of the minimum amount


The minimum tax is a minimum for the collection of corporate income tax. In Chad, it is fixed at 1.5% of company turnover. However, this minimum tax is accompanied by a minimum amount for companies with low turnover. This amount was amended by the Finance Act, 2019 (Act No. 037/PR/2018 of 31 December 2018). The floor amount of the minimum tax increases to 2 million CFA francs for large companies, while it remains at 1 million CFA francs for small companies.

Revision of the Tanzanian Mining Act: what changes?


The Tanzanian Mining Act was revised, mainly in 2017 (Act No. 7 of 2017). Mining royalty rates have been increased from 4% to 6% for gold. In addition, the free equity for the State in the capital of the mining company, the rate of which had hitherto been negotiated between the parties, is now set at 16%. Finally, the amount of fixed fees and surface fees were reduced in 2018 (Government Notice No. 1 of 2018). These new measures concerning the mining royalty and the State equity significantly increase the tax burden applicable to gold mining companies. For a representative medium grade mine (3g/t) and a gold price of $1250/oz, the average effective tax rate (AETR) increases from 41% to 53%.
