Spain's Tax Agency Issues Renta 2025 Guidance and Mi Carpeta Ciudadana Tool

The Spanish Tax Agency (Agencia Tributaria) has launched a campaign to help taxpayers prepare for the 2025 income‑tax filing season. It urges citizens to verify key personal data – such as fiscal address, bank account, family status, and income details – and to obtain the reference number needed to access the online filing system. The agency highlights that many steps can be completed remotely, reducing errors and delays.

In parallel, the agency promotes the use of the official "Mi Carpeta Ciudadana" app. Through its "Transparencia" section, users can audit which public bodies have consulted their tax records, filter by date, and receive real‑time notifications when a new query occurs. This feature allows taxpayers to detect any unexpected data checks within minutes, providing an additional layer of transparency and security.
