Tax Incentives

What are tax incentives?  

Tax incentives are fiscal terms designed to reduce the cost of investment by lowering an investor’s tax liability. Governments sometimes choose to offer these incentives to induce mining investment. Tax incentives can be divided into two broad categories: 

  • Profit-based tax incentives, that reduce the quantum of tax payable by an investor—for example, by granting investors tax holidays or reducing the applicable tax rate. 
  • Cost-based tax incentives, that defer the payment of tax due to the government—for example, through the extension of extended loss carry-forward periods or accelerated depreciation. 

 

What are the risks of poorly designed tax incentives? 

Tax incentives in mining are common in developing countries, but their effectiveness is often disputed. While the incentives may encourage mining sector growth, they can also be overly generous and unnecessarily divert tax revenue away from host governments. 

For example, if a mine is given a time-limited tax holiday, a mining company may respond by speeding up the rate of production to maximize its tax-free revenue during the period. This leaves less ore to be extracted after the tax holiday expires, which would further reduce government revenue. 

For these reasons, it is important that policy-makers understand when tax incentives may be appropriate, what type of incentives are most beneficial, and how companies are likely to respond to incentives. 

Navigating Tax Incentives in Mining: Guidance and resources

  • Tax Incentives in Mining: Minimising Risks to Revenue (in collaboration with the OECD) focuses on the taxpayer’s behavioral responses and the unintended consequences that may flow from tax incentives. It includes a step-by-step guide to reviewing tax incentives and specific risks to revenue, as well as a checklist to help governments assess behavioral responses and revenue impacts. 
  • The IGF Financial Model can be used to estimate the cost of tax incentives in mining, including behavioral responses as set out in our practice note. It can be modified in multiple ways to reflect different assumptions and parameters. Users who intend to adapt the model should first read our supplementary guidance. 
  • The IGF Mining Tax Incentives Database provides the most granular view yet of tax competition in mining, showcasing how common tax incentives are in the sector. Our research compares the fiscal regimes of 104 mining projects across 21 countries and is the first large-scale, systematic attempt to compile tax incentives used by developing country governments to attract mining investment. 
  • Rethinking Tax Incentives in Mining in Africa (in collaboration with UNECA) explores how tax incentives in the African mining sector can be redesigned to better balance attracting investment with ensuring fair revenue generation for governments. 
  • Revisiting Tax Incentives as an Investment Promotion Tool examines whether tax incentives are efficient in attracting investment, their legal implications, and future role in investment policy. 
  • Tax Incentives in Investment Laws maps how tax incentives are embedded, designed, and governed across national investment laws in developing economies, highlighting weak coordination, fragmented legal frameworks, and gaps in oversight between investment and tax authorities.

Watch our Webinar on Tax Incentives in Mining in Africa

Across Africa, the use of tax incentives in the mining sector remains widespread. However, evidence suggests many of these incentives are poorly designed, overly generous, and not well aligned with development goals. In a sector where investment decisions are often driven by factors such as deposit quality, infrastructure, and political stability, tax incentives alone play a more limited role than traditionally assumed and are causing unnecessary revenue losses.

This webinar discusses how African countries can adopt more effective, transparent, and development-oriented mining tax incentive frameworks, drawing on recent analysis and examples from across the continent.
