The statistics on Personal Income Tax (IRPF) Return Filers for 2024 offer a detailed examination of who submitted tax returns in the 2024 fiscal year and how their financial profiles compare. Published on 1 July 2026, the dataset enumerates the total number of individual filers, distinguishes between primary earners, spouses, and dependents, and records demographic variables such as age, gender, and region of residence. Income brackets are presented, showing the distribution of taxable bases across the various marginal tax rates that apply in Spain. The report also includes metrics on the proportion of filers who claim deductions, credits, or exemptions, and it quantifies the average taxable income per category. Special attention is given to the participation of different economic sectors, with separate tables for employees, self‑employed professionals, and owners of capital assets. The Agency highlights trends such as an increase in electronic filing among younger taxpayers and a modest rise in the number of high‑income filers compared with the previous year. Moreover, the statistics provide an overview of the compliance rate, indicating the share of returns that were subject to verification or audit. These insights assist tax policymakers in evaluating the effectiveness of recent reforms, in forecasting revenue from personal income taxes, and in designing targeted measures to support particular demographic groups. The data are accompanied by methodological notes describing the classification criteria and any adjustments made for the 2024 filing period.
