Tax Lawyers in Buenos Aires

Tax compliance and smart tax planning are key elements for protecting assets and sustaining business growth in international contexts. As tax lawyers, we assist companies and investors in reducing risks, optimizing the tax burden and regularizing their situation before ARCA (Argentina's Revenue and Customs Agency).

Our team of tax attorneys provides personalized tax advisory, tailored to each client's profile and country of tax residency. We handle everything from defense in tax enforcement and assessment proceedings to planning international structures, double taxation treaties and transfer pricing, working with allied accountants and tax advisors across multiple jurisdictions.

We operate with a preventive and strategic approach: we anticipate tax contingencies, design efficient tax planning structures and defend our clients' interests before ARCA, tax courts and international bodies.

Frequently Asked Questions

A tax lawyer advises on tax planning, defends clients before AFIP/ARCA in tax assessment proceedings, represents them in criminal tax cases and designs tax-efficient structures for companies and investors. Unlike an accountant, a tax attorney intervenes when a dispute with the tax authority requires legal defense or when the complexity of the transaction demands specialized legal analysis.

An accountant handles the filing and preparation of tax returns (income tax, personal assets tax, VAT). A tax lawyer intervenes in complex tax planning, defense before the tax authority in assessment and enforcement proceedings, tax litigation in court, and legal structuring of international operations such as transfer pricing or double taxation treaties.

You need a tax attorney when you face a tax assessment or enforcement proceeding from ARCA, a criminal tax case, when you need to plan the tax aspects of an investment or corporate restructuring, when changing your tax residency between countries, or when you require advice on international double taxation and tax treaties.

Tax planning is the design of legal strategies to optimize the tax burden for individuals and companies. It includes choosing the most efficient corporate structure, analyzing available tax incentives, applying double taxation treaties, and managing tax residency. Professional tax planning allows you to reduce taxes within the current legal framework.

Argentina has double taxation treaties with more than 20 countries that prevent the same income from being taxed twice. These treaties establish which country has the right to tax each type of income (dividends, interest, royalties, services) and mechanisms such as tax credits or exemptions to eliminate double taxation. A tax lawyer can help correctly apply these treaties to minimize the international tax burden.
