Evaluación de la fiscalidad autonómica: descentralización tributaria y desigualdades fiscales interregionales en materia de tarifas y deducciones autonómicas en el IRPF

Abstract

El objetivo de este trabajo es combinar un enfoque teórico y empírico para evaluar las desigualdades fiscales interregionales derivadas de la capacidad normativa de las Comunidades Autónomas en el ámbito del IRPF, centrándose en el caso de Cantabria. Se parte de un análisis normativo a partir de fuentes secundarias, entre las que destaca el informe Panorama de la Fiscalidad Autonómica y Foral, que permite identificar y comparar las competencias fiscales ejercidas por las distintas CC.AA. Asimismo, se incorporan datos de la Ley Orgánica de Financiación de las Comunidades Autónomas y de la Subdirección General de Relaciones Tributarias, lo que proporciona una visión detallada de las medidas fiscales adoptadas en el ejercicio fiscal 2022. Posteriormente, se selecciona una muestra de CC.AA. (Cantabria, Galicia, Extremadura, La Rioja y la Comunitat Valenciana) con diferencias significativas en número y tipología de deducciones autonómicas, así como en tarifa. Adicionalmente, se realiza un análisis descriptivo de las deducciones autonómicas para cada C.A en el ejercicio impositivo, estudiando aspectos como el número de beneficiarios, el importe total deducido y la deducción media, normalizando los datos en términos relativos. Finalmente, se desarrolla un análisis empírico basado en simulaciones de declaraciones del IRPF mediante el simulador “Renta Web Open”, de una familia española prototipo. Esta metodología permite valorar y obtener unas conclusiones sobre si la capacidad normativa genera desigualdades fiscales significativas entre contribuyentes con las mismas circunstancias personales y familiares, en función de la C.A. en la que ejerza su tributación

This paper combines a theoretical and empirical approach to assess interregional tax inequalities arising from the regulatory powers of Spain’s Autonomous Communities in the field of Personal Income Tax (IRPF), with a focus on the case of Cantabria. The analysis begins with a normative review based on secondary sources, notably the Overview of Regional and Foral Taxation report which enables the identification and comparison of the fiscal powers exercised by the different regions. Additionally, data from the Organic Law on the Financing of Autonomous Communities and the Sub-directorate General for Tax Relations is incorporated, providing a detailed overview of the tax measures adopted in the 2022 fiscal year. A sample of Autonomous Communities (Cantabria, Galicia, Extremadura, La Rioja, and the Valencian Community) is then selected based on significant differences in the number and types of regional tax deductions, as well as in the applicable tax rates. A descriptive analysis of these deductions is conducted, examining variables such as the number of beneficiaries, total amounts deducted, and average deduction per taxpayer, with data normalized in relative terms to enable cross-regional comparisons. Finally, an empirical analysis is carried out through simulated Personal Income Tax returns using the “Renta Web Open” tool, based on a prototype Spanish family. This methodology makes it possible to evaluate whether the regulatory powers of the regions lead to significant tax disparities among taxpayers with identical personal and family circumstances, depending on the region in which they reside
