ATSA S.L. emerged in 2012 from the collaboration between Andorran and Spanish advisers.
Since 2000, tax requirements in the Principality of Andorra have increased, leading to the introduction of Corporate Tax in 2012 and Personal Income Tax (IRPF) in 2015.
At this point, many advisers, who had already been collaborating for more than 10 years, decided to combine their knowledge of the Andorran market and the tax world to create the Andorran company ATSA, SL, offering comprehensive services to its clients.
ATSA, SL is a subsidiary of the Spanish company ASESORÍA TRIADÚ, SA (ATSA), which belongs to the international group MORISON ACPM, present in more than 85 countries.
