SK&S was one of the first Polish law firms to establish a dedicated Tax Department. The Department, founded and headed by Jarosław Bieroński, provides highly specialized advice which includes: representing clients before the Supreme Administrative Court and government bodies, planning and assessing transactions concerning their tax optimization and coherency, conducting tax mediation, assisting in obtaining official interpretations of tax law provisions and binding tariff information, participating in tax audits, and preparing transfer price documentation. The favourable judgments we have obtained from administrative courts on numerous occasions have prepared the ground for new interpretations by the tax authorities. Many of the optimization solutions developed by the Department are novel in nature and have been developed in strict cooperation with experts from other fields of law to provide legal coherence in transactions performed with SK&S’ assistance. Significant projects have included tax planning and investment implementation in Poland.
