Felipe Gavilán

Felipe is a partner at RGS. He holds a law degree and a Master in Tax Law, both from Universidad de Chile.

Felipe has more than 20 years of experience in tax controversy, tax consulting, and criminal tax law. He advises clients through the full arc of a dispute: from audits and administrative proceedings before the Chilean tax authorities to litigation in the Tax and Customs Courts, Courts of Appeals, and the Supreme Court. He has consistently obtained favorable outcomes at both the administrative and judicial levels.
Several of the rulings he has obtained have become reference points in Chilean tax practice, shaping how key questions are now interpreted and argued by taxpayers, advisors, and the tax authorities alike.

Before joining RGS, Felipe served as Director and Head of Dispute Resolution and Tax Litigation at KPMG Chile for six years. Earlier, he spent nine years at the Legal Sub-Directorate of the Chilean Internal Revenue Service, which gave him a thorough understanding of how the tax authorities approache audits and litigation.

His clients include Cencosud, Sony Chile, Polpaico, DHL Global Forwarding, Anglo American Chile, Credicorp Chile, Antofagasta Minerals, Deutsche Bank Chile, Compañía Sud Americana de Vapores, Grupo Brookfield, among other companies operating across Chile’s main economic sectors.

Over more than a decade of practice, Gonzalo has designed and implemented the tax compliance strategy of Chilean and multinational groups operating across regulated and high-volume industries, including software, energy, retail, consumer goods, and automotive. His work spans the full compliance cycle: corporate and individual income tax, deferred taxes, VAT, withholding taxes, sworn statements, tax assessments, diagnostics, and due diligence, as well as the accounting and tax execution of domestic and cross-border corporate reorganizations.

Before joining RGS, Gonzalo spent ten years years in Big Four tax practices: over four years at KPMG, followed by more than five years at EY, where he became Manager in the Tax Compliance department.

Macarena Vera

Macarena is an attorney. She graduated from Universidad de Chile’s Law School. She joined RGS in 2017 with the mandate of building the firm’s corporate practice, where she has established herself as a fundamental resource in the design of the legal documentation required in highly complex international advisory engagements. She works in close coordination with the firm’s tax and audit team, translating legal strategy into the contracts, corporate resolutions, and filings that bring each transaction to life.

Macarena has actively collaborated in the cross-border expansion of Chilean technology startups, designing the corporate and contractual documentation that has enabled such expansion and reviewing and validating foreign-law documentation to ensure its consistency with the client’s global structure. She has also led the design and implementation of the documentation required to support the intragroup contractual relationships that these cases demand, from both a legal and a transfer pricing perspective.

As a key part of her practice, Macarena assists international companies in their establishment and operation in Chile. Her command of local tax and regulatory matters has been instrumental in advising foreign clients entering the Chilean market to operate concessions, distribute advanced-technology goods and software, and carry out other strategically relevant activities.

In the area of mergers and acquisitions, Macarena works in an integrated manner with RGS’s audit team on the design, documentary support, and execution of these processes, as well as on the corresponding reporting to the tax authority. This joint approach ensures that the legal, accounting, and tax dimensions of each transaction are aligned from day one.
