 Tax Base Dynamics and Revenue Trends in Spain: A Comparative Analysis of Major Taxes (1995–2023)Fernando Pinto, Alfredo Cabezas-Ares and Miguel Ángel Alonso-Neira Journal of Tax Reform, 2025, vol. 11, issue 3, 692-712 Abstract: Understanding the responsiveness of tax systems to economic fluctuations is essential for designing stable and effective fiscal policies. Spain’s tax structure built around personal income tax (PIT), corporate income tax (CIT), value-added tax (VAT), and excise taxes (ET), has experienced significant stress due to the financial crisis of 2008 and the COVID-19 pandemic in 2020. We analyze annual data from 1995 to 2023 from the Spanish Tax Agency, estimating long-run elasticities of tax revenues with respect to their bases using log-linear regressions. We complement this with short-term variation rate models and Chow-type structural break tests. VAT exhibits the highest long-run elasticity (1.12), followed by PIT (0.96), CIT (0.85), and ET (0.72). Short-run responsiveness follows a similar ranking. Structural break analysis confirms significant changes post-2008 for CIT and VAT, and post-2020 for VAT and ET. PIT remains relatively stable across shocks. Theoretically, these results confirm that indirect taxes like VAT are more responsive to economic activity, validating their classification as highly elastic instruments and reinforcing their role as automatic stabilizers– albeit with increased vulnerability during downturns. In contrast, PIT’s moderate elasticity and structural stability support its role as a countercyclical anchor in public finance models. Practically, our findings offer key insights for fiscal policy design in Spain. Policymakers can leverage VAT’s buoyancy during expansions while relying on PIT for consistent revenue in crises. CIT and ET, due to their volatility, should be complemented with stabilization mechanisms. The results help assess Spain’s fiscal space and resilience, especially under exogenous shocks like financial crises and pandemics.
