Understanding and modelling the sharing of mining and petroleum rents

Context and learning objectives

The issue of a fair distribution of mining and petroleum rents often comes back to the forefront, especially when commodity prices are high.


 This course first reviews the key challenges of the extractive sector in Africa, then explains the different fiscal and parafiscal instruments that can be used to tax mining companies. Participants will learn step-by-step how to model the sharing of rents.


 Throughout the training, we will build an Excel-based cash flow model to estimate how resource rents are split between the State and investors.


 This is the first online module of the “Natural resource management for development” programme.

Module 8 • Production sharing
1 h

The objective of this module is to understand production sharing. In the oil sector, it is indeed common for the contract to provide for the sharing of production between the state and the contractor, which first involves calculating the cost oil and then sharing the profit oil.

30 min

The objective of this module is to be capable of modeling production sharing in Excel for the oil sector.

Module 9 • Corporate income tax (CIT) and minimum tax (MT)
1 h 30

The first part of this module aims to understand how the loss carryforward works, which constitutes a deductible charge in the calculation of the corporate income tax, as was the case for amortization expenses and financial expenses.

The second part of this module takes up these elements to explain the operation of income taxes such as corporate income tax and minimum tax, their calculation methods as well as their economic implications for an extractive project. After a theoretical reminder, we will move from theory to practice of tax calculation in the extractive sector.

Module 9.m • Calculation of corporate income tax and minimum tax in the mining sector
45 min

The objective of this module is to be able to calculate the corporate income tax and the minimum tax in Excel in the mining sector.

The goal of this module is to understand what a feasibility study is. This document can serve as a source of economic and fiscal data for the rent-sharing model. The accuracy of the data entered into the model is crucial, as the quality of the modelling results depends on it.

Module 15 • Tax law
2 h

This module covers key concepts in tax and mining law. Knowing the relevant legal texts—and being able to read and interpret them— is essential to understand a country’s fiscal system and collect the necessary tax data for the rent-sharing model.

Module 16 • Interpreting results

Once the model is built, you need to be able to read it. This module shows you how to interpret outcomes and present them effectively—such as through a short briefing note supported by clear charts and graphs.

Module 17 • Running simulations
1 h 30

Once your mining rent-sharing model is complete, running simulations becomes easy: simply adjust the economic or fiscal data. This allows you to compare the results of multiple alternative scenarios with the baseline scenario.
