Repenser les incitations fiscales en tant qu’outil de promotion des investissements

The document argues that tax incentives are often ineffective at attracting investment and may be rendered redundant by the 15% global minimum tax (GloBE rules) starting in January 2024. It recommends shifting from profit-based incentives to cost-based incentives and improving governance through transparency and inter-agency coordination.

• Tax incentives are not generally a prerequisite for attracting investment, and evidence suggests that many investments would have occurred even without them.
• The OECD/G20 global minimum tax (Pillar 2) requires multinational enterprises with annual revenues of 750 million euros or more to pay an effective tax rate of 15% in all jurisdictions, which will make certain tax incentives redundant.
• Profit-based incentives, such as tax holidays and free export zones, are highly susceptible to the global minimum tax because they significantly reduce the effective tax rate, potentially leading to top-up taxes in other jurisdictions.
• Cost-based incentives, such as accelerated depreciation and investment deductions, are preferable to profit-based ones because they reduce the cost of capital and are less likely to be abused or trigger top-up taxes under GloBE rules.
• Legal reforms to tax incentives are complicated by 'fiscal stabilization' clauses in investment contracts and international treaties, which may limit a government's ability to modify tax laws without providing compensation.
• Effective governance of tax incentives requires transparency, public consultation, and a 'whole-of-government' approach involving the ministry of finance and tax administration.
