Our Services

We provide specialized tax advisory services to plan, manage and resolve our clients’ tax matters. Our practice covers preventive structuring and regulatory compliance, as well as representation in tax controversies and support in corporate and financial transactions.

Advisory Services

Tax planning and structuring

We advise on the tax planning and structuring of domestic and cross-border operations, including corporate reorganizations, financings, investments and long-term projects. Our work focuses on assessing tax implications, identifying risks and designing efficient structures aligned with our clients’ business strategy.

Compliance and ongoing obligations

We support clients in meeting their recurring tax obligations and in the correct application of applicable regulations. Our team reviews relevant tax positions, assists in the preparation and documentation of key requirements, and helps design internal processes that promote certainty and reduce exposure to potential contingencies.

Tax support in corporate and financial transactions

We participate in mergers and acquisitions, joint ventures, divestments and financing transactions, evaluating the tax impact of each proposed structure. We work closely with corporate, financial and regulatory teams to ensure that every transaction is implemented with sound, well-documented and sustainable tax design.

International tax and treaty matters

We advise on the application of double-taxation treaties, permanent establishment rules and withholding obligations in cross-border operations. Our work includes analyzing investment structures, capital flows and intercompany payments, offering solutions that comply with applicable standards and provide long-term certainty.

Tax Controversy

Audits and tax authority reviews

We represent taxpayers in audits, desk reviews and on-site inspections initiated by the tax authorities. We assist at every stage—from responding to information requests to addressing preliminary findings—ensuring positions are well supported and risks are properly managed.

Administrative procedures and defense mechanisms

We design and implement defense strategies in administrative proceedings, including refund requests, administrative remedies and other mechanisms for dialogue with the authorities. Our approach combines solid legal arguments with practical alternatives to mitigate risk and protect cash flow.

Strategic tax litigation

We litigate tax disputes before administrative and judicial courts, challenging assessments, penalties and other actions that impact our clients’ operations. Our team focuses on building technically robust cases supported by legal criteria and aligned with the taxpayer’s business objectives.

Negotiation and dispute resolution

We assist in negotiating and resolving complex controversies with tax authorities, assessing risk scenarios, economic exposure and available regularization alternatives. We participate in strategic discussions and settlement processes to achieve solutions that provide certainty and allow clients to focus on their core business activities.
