What is a Chartered Tax Expert Witness?
A Chartered Tax Expert Witness is a highly specialised professional in taxation who acts as an expert before the courts, providing technical expertise in legal proceedings involving tax law. Their main functions include: technical advisory work, preparation of expert reports, interpretation of tax regulations, court testimony, mediation and extrajudicial expert assessment…
At Apse, we offer specialised tax expert witness services aimed at companies and individuals who require rigorous technical analysis in tax matters. From our Madrid office, we provide professional coverage to clients throughout Spain, acting in both judicial and extrajudicial tax-related proceedings.
Tax expert witnesses focused on excellence
Our team of expert witnesses in taxation holds the academic training, professional accreditation and practical experience required to approach each case from a strategic, objective and well-founded perspective. Each assignment is analysed individually, evaluating the different technical and legal options available. We also provide ratification and defence of expert reports in court, either in coordination with the client’s legal representatives or acting as expert support when required.
In most cases, our experts have already worked on and participated in proceedings similar to yours. This practical experience allows us to anticipate scenarios, minimise risks and act with confidence in the face of any issues that may arise during the process.
Internal procedures and report preparation are carried out under strict quality protocols. Our organisation is ISO 9001:2015 certified, which ensures a structured, audited working system focused on continuous improvement.
➣ Tax expert reports for judicial or private proceedings.
➣ Tax inspections, tax audits and specialised technical-accounting analysis.
➣ Valuations and tax studies with objective criteria defendable before third parties.
Support in all types of tax proceedings
Technical and legal assistance is provided in disputes, inspections, assessments and claims before the Tax Agency and other economic-administrative bodies. The service includes prior case analysis, document review and full preparation of proceedings, both in administrative and judicial stages.
Likewise, we carry out voluntary tax audits aimed at companies that wish to accurately understand their tax and accounting situation, detect contingencies and make informed decisions before any dispute arises.
Our working methodology is distinguished by close client interaction and operational agility. Collaboration can be established on a one-off or ongoing basis, adapting to the specific needs of each organisation.
Assistance for both claimant and defendant
The service adapts to the procedural position of the client. Whether the tax authorities have initiated action against your company or you intend to challenge a tax decision.
In any case, a prior technical assessment will realistically estimate the chances of success and define the most appropriate strategy.
Tax expert services for individuals
Individuals, especially those with significant assets or complex tax structures, may also require the assistance of a tax expert witness. In such cases, precise and confidential technical advice is provided, focused on defending their interests before the tax authorities if necessary.
A multidisciplinary team at your disposal
The support of a team of lawyers specialised in different areas of law allows us to address highly complex matters with a comprehensive perspective. This coordination between experts and legal professionals strengthens the technical and legal robustness of each case.
