Overview
The Agencia Tributaria offers several ways to get help, from general phone lines to in-person appointments. Knowing which channel fits your specific query saves time compared to guessing.
Requirements
- Relevant to anyone with a tax query in Spain, resident or non-resident
Step-by-step process
- For general information queries, use the Agencia Tributaria's general information phone line, which can often answer common questions without an appointment
- For queries requiring your personal tax data, use the automated phone line or online chat with Cl@ve/digital certificate verification, since general information lines can't access individual records
- For in-person queries, book a cita previa (prior appointment) at your local Agencia Tributaria office — walk-ins are generally not accepted
- For written queries or formal responses to a notification, use the Sede Electrónica's registered submission system, which provides a dated proof of submission
Required documents
- NIE/NIF for any query involving your personal tax data
- Cl@ve or digital certificate, for identity verification on personal queries
Common mistakes
- Turning up to an office without a cita previa, when appointments are generally required for in-person procedures
- Using the general information line for a query that actually requires access to your personal tax record, when a different verified channel is needed
Practical tips
- Book any needed in-person appointment as early as possible, especially close to the Renta filing deadline, when demand for appointments rises sharply
- For written communications you may need to prove you sent, always use the Sede Electrónica's registered submission rather than informal email, since it provides dated, verifiable proof
