We provide specialized tax consultancy based on economic activity, tax planning with emphasis on cross-border operations, tax advice on corporate reorganizations, and tax due diligence services. We assist our clients during the tax examination processes and lead the defense in administrative and judicial proceedings.

We are actively involved in the development of a pioneering practice in environmental taxation. We advise foreign investors in the preparation and successful presentation of regulatory proposals on tax matters that have made possible the performance of large investment both in mining and oil issues currently in operation.

We have advised in the conclusion of tax stability agreements that translate to more than US$ 10 000 MM of total investment. We advised on the application of the Agreements to avoid Double Taxation signed with Canada, Chile, Brazil, Mexico, Korea, Portugal and Switzerland, as well as Decision 578, which establishes the regime to avoid double taxation among the Andean Community countries. We advise our clients to implement the most efficient contractual and corporate structure from a tax perspective.

We perform tax audits for privatizations and acquisitions and mergers projects of banks, steel mills, industrial companies, supermarkets, mining companies, oil companies and electricity companies.
