Our Spanish tax lawyers have a broad experience in different types of procedures before the Spanish Tax Authorities, such as:


  • Assistance and representation of individuals (self-employed workers) and companies in procedures of tax inspection.
  • Assistance and representation in tax management and tax collection.


Our specialists’ wide knowledge of such procedures guarantees that any actions undertaken will result in the most favourable decisions possible from the Tax Agency. In our experience, the complexity and implications that can result from these proceedings makes collaboration with our professionals at every stage essential.

Legal assistance & representation before Spanish Courts and


The team of specialist fiscal lawyers has solid experience in the development of proceedings before courts and tribunals. Prior analysis of the case by our professionals is essential so that an individual or company can take the best decision as to whether they wish to continue with proceedings of this kind or not. AGM Abogados will not embark upon procedures we deem will be unsuccessful and we will always inform the client about the feasibility of their appeal.


According to statistics from the Spanish Tax Agency, nowadays, most proceedings brought before courts and tribunals by taxpayers end positively for them.


Our team of expert Spanish tax lawyers offers the following services:


  • Appeals before Administrative Agencies and claims before Regional and Central Economic-Administrative Courts (TEAR & TEAC).
  • Legal representation in tax procedures before the Contentious-Administrative Courts and Tribunals in all kinds of appeals against administrative acts dictated by the state, autonomous communities and local authorities.
  • Defence in administrative disciplinary proceedings and derivations of liability brought against a company’s governing bodies, and objection to precautionary measures, as well as defence in cases of crimes against the Public Treasury.
