Péter Barta

Péter focuses primarily on tax advisory, tax audit defense, and the representation of clients in tax litigation and white-collar crime proceedings. As a seasoned tax advisor and certified tax expert, he advises on the full range of tax issues, including value added tax, corporate income tax, and personal taxation. His specializations include guiding clients through tax audits, optimizing tax structures, and defending them in procedures launched by the Hungarian Tax Authority. In parallel, he has built a strong reputation as a fraud defense lawyer in Budapest, representing clients in complex white-collar crime cases involving tax fraud, embezzlement, and other economic offenses. Péter’s ability to combine deep legal insight with financial understanding positions him uniquely to manage cases where legal and accounting dimensions intersect.

Péter started his legal career in 2013 at one of the Big Four firms, gaining valuable experience in tax advisory, audit-related procedures and accounting. Shortly after, he joined Jalsovszky, where he has played a key role in building and shaping the firm’s tax litigation, tax advisory and dispute resolution practice. Over more than a decade, he has advised clients in hundreds of tax-related matters, tax audits, tax procedures and criminal procedures. His work often involves close collaboration with accounting professionals, auditors, and corporate decision-makers. Thanks to his comprehensive understanding of both the substantive and procedural aspects of Hungarian tax law, he is frequently consulted in high-stakes matters where strategic thinking and technical precision are critical.

Throughout his career, Péter has successfully represented clients in a wide range of sensitive and high-stakes tax matters. These include tax audits and tax procedures involving hundreds of millions of forints, complex tax advisory and tax restructuring works, and the defense of corporate executives accused of tax evasion or fraud. He has assisted clients in proceedings before both the Hungarian Tax Authority and courts, often achieving the reduction or elimination of tax liabilities and the avoidance of criminal charges. His courtroom experience includes representing clients in white-collar crime cases involving VAT carousel fraud, falsification of accounting records, and misuse of corporate assets. 

Péter holds degrees in both law and economics and is a certified tax advisor, tax expert, accountant and licenced attorney. In addition, he has obtained two LL.M. degrees – one focusing on Hungarian tax law and another in international business law – which enhance his ability to manage cross-border tax cases and interpret international legal frameworks in a domestic context. His educational background enables him to advise clients not only as a lawyer but also as an expert who understands the language and logic of accounting and business operations. This dual competence is particularly valuable in tax advisory, tax litigation and white-collar crime cases, where financial documentation and economic interpretation are often essential to the legal argument.

Beyond his day-to-day legal work, Péter is a frequent speaker and lecturer on tax law, tax audit strategy, and corporate fraud topics. He regularly teaches at the Education Centre of the Hungarian Chamber of Auditors (MKVKOK) and is invited to speak at business law seminars, tax forums, and legal training programs. His thought leadership and professional activity have been recognized with several awards, including Tax Advisor of the Year (Penta Union, 2018), Young Talent of the Year, and Tax Team of the Year (Wolters Kluwer). These contributions reflect his commitment to the continuous development of the tax profession and highlight his standing as one of the most active tax experts in Hungary. His ability to clearly communicate complex issues also makes him a reliable partner for international clients navigating Hungarian tax matters and tax procedures.
