Our approach

Lawful and sustainable
tax optimisation

Our objective is not to pay the lowest possible amount of tax, but to design robust, transparent and compliant tax structures that enable our clients to make decisions with complete certainty and a long-term view.

We combine local expertise in each jurisdiction with an international perspective: we have a deep understanding of the tax regimes of Andorra, Spain and France, the applicable double-taxation treaties and the international reporting obligations (CRS, BEPS).

What is the difference between tax optimisation and tax evasion?
+
Tax optimisation consists of taking advantage of the benefits, deductions and incentives provided for by the law in order to reduce the tax burden lawfully. Tax evasion involves concealing income or assets so they are not declared; it is illegal and carries severe sanctions. Our work always falls in the first category: lawful, transparent and compliant structures.
What is a DTT and how does it benefit me?
+
A Double-Taxation Treaty (DTT) is a bilateral agreement between two countries to ensure that income obtained in one country by a resident of the other is not taxed twice. Its correct application can lead to very significant tax savings for individuals and companies operating across several jurisdictions. Andorra has DTTs in force with Spain, France, Portugal, the United Arab Emirates and other countries.
What is the CRS and does it affect my bank accounts?
+
The Common Reporting Standard (CRS) is the automatic exchange of tax information system among OECD countries. Banks in virtually every country in the world automatically report account balances and movements of non-residents to the tax authorities of the holder’s country of residence. Tax transparency is now total. We advise on how to comply correctly with these obligations.
When is voluntary tax regularisation advisable?
+
Whenever there are unfulfilled tax obligations, voluntary regularisation, before the administration commences an inspection, allows the applicable penalties and surcharges to be significantly reduced. Filing a late return with a surcharge is always less costly than an inspection that ends in a penalty.
Can you manage the taxation of my group with presence in several jurisdictions?
+
Yes. It is one of our strengths. For groups with a presence in Andorra, Spain and France, we coordinate the tax teams of the four offices from a single point of contact. The client receives a consolidated view of the group’s tax position and a single point of contact for the entire structure.
