Expertise, experience, trustworthiness, a holistic approach and an international perspective are the hallmarks of the tax advising services that our firm offers individuals and companies. A team of experienced tax lawyers with the highest education and a broad professional career in the area are the ones in charge of offering a service with the best guarantees required by your company, either with a permanent advice or an occasional one.


Conscious that time is money; we deal with and take responsibility for the various procedures that may need to be managed before courts and tribunals, as well as the Tax Agency.

Thanks to our proven international network, we are able to offer our clients coverage beyond across borders in all kinds of business operations: mergers and acquisitions (M&A), joint ventures, the expatriation of professionals, investments and linked operations, among many others.


Further, we count on highly specialised lawyers in order to address the specific needs that complex processes such as the issue of succession in family businesses or tax planning for non-profit organisations require, offering our clients solid experience in advising these types of organisations.


It should be pointed out that one of our partners in this area, the lawyer and partner Leonardo Cárdenas Armesto, is the Head and Coordinator of the family business area at AEDAF (Spanish Association of Tax Advisors).

Within the areas of our Tax Law Department, we provide special attention to the following matters:

Proceedings before the Tax Agency

Our professionals have a broad experience in different type of procedures before the Tax Agency, 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’ 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.

Proceedings before the Courts and Tribunals

The team of specialist lawyers in the fiscal domain 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 will inform the client about the feasibility of their appeal at all times.


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


The team of expert lawyers in the area of taxation offers the following services:


  • Appeals before Administrative Agencies and claims before regional and central Economic-Administrative Courts.
  • Legal representation in tax procedures before the Contentious-Administrative Courts and Tribunals in all kind 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 opposition to precautionary measures, as well as defence in offences against the Treasury.
