On 21 October 2026, the Foreign Investors Tax Committee (Comité Fiscal de Inversores Extranjeros) published its annual “Barómetro de Inversión,” identifying five structural tax barriers that caused a 17% drop in greenfield FDI projects in H1 2026 vs. H1 2025. The barriers: (1) Unpredictable retrospective changes (e.g., 2023 limitation of deductibility of financial expenses, 2024 patent box modification); (2) Complexity of regional tax variance (17 different ISD, Wealth Tax, and ITP/AJD regimes); (3) Slow advance pricing agreement (APA) process (avg. 38 months vs. OECD 24-month standard); (4) Lack of binding rulings for mid-market firms (consultas vinculantes only for >€6M transactions); (5) Aggressive transfer pricing adjustments without corresponding competent authority relief, leading to double taxation. The report estimates these factors add 4-6% effective tax rate premium vs. Portugal, Ireland, or Netherlands.
Key Takeaways
- Policy Instability Cost: Retroactive measures since 2020 have increased the “tax risk premium” demanded by foreign boards, with 62% of surveyed MNE tax directors citing “legislative unpredictability” as top concern.
- Regional Fragmentation: A single Spanish holdco faces up to 17 different inheritance tax treatments for employee equity plans depending on assignee’s region, complicating mobility programs.
- Action Plan: The Committee proposes a “Tax Certainty Charter” with: statutory stability clauses (5-year freeze), national APA fast-track, and a unified digital ruling portal for all investor tiers.
