RÉFORMES DE LA FISCALITÉ NUMÉRIQUE INTERNATIONALE ET EXPLOITATION MINIÈRE : LA QUESTION DES DIFFÉRENCES TEMPORELLES

The document analyzes the risks posed by the OECD's Pillar Two (GloBE) rules to the mining sector, specifically regarding 'timing differences' between accounting profits and taxable income. It argues that without proper resolution, these differences—often caused by accelerated depreciation—could lead to double taxation and the transfer of tax revenues from developing nations to the home countries of multinational corporations. The report evaluates three potential solutions: loss carry-forwards/tax credits, deferred tax accounting, and the use of local tax rules.

• The Pillar Two (GloBE) proposal aims to establish a global minimum effective tax rate (ETR) to reduce tax competition and profit shifting, potentially discouraging costly tax incentives like tax holidays.
• Timing differences occur when there is a gap between the accounting profit used for the GloBE ETR and the taxable profit determined by national tax laws. In mining, this is prevalent because capital expenditures are often depreciated faster for tax purposes than for accounting purposes.
• If timing differences are not resolved, resource-rich developing countries risk losing mining investments and tax revenues, as top-up taxes would be paid to the parent company's home country rather than the host country.
• The report assesses three solutions for timing differences: a combination of loss carry-forwards and tax credits (deemed insufficient for capital-intensive industries), deferred tax accounting (considered a simple and transparent method if abuses are prevented), and the use of local tax rules (which reduces judgment but increases administrative complexity).
• Permanent differences, such as tax holidays, are also problematic. Because many mining contracts contain stabilization clauses, developing countries may be legally unable to remove these incentives quickly, potentially leading to a double loss of revenue.
