Our experience in tax law covers all aspects of transfer prices, compliance and support of fiscal and administrative court proceedings.

Our experienced tax advisors act in the taxpayers’ best interest; we defend taxpayers’ rights and look after security of their business.

Our law department provides ongoing legal support to start-ups and in the e-commerce sector.

Law, taxes and accounting are disciplines where constant professional development is fundamental. Regulations tend to change and often are open to inconsistent interpretations, which necessitates regular participation in trainings, courses, conferences and other forms of professional development.

    Accounting Services in Poland

    Central Europe’s strategic gem, Poland, with its bustling economy, well-established infrastructure, and vibrant market, provides a favorable environment for business growth. The appeal of the Polish market to overseas investors has consistently grown over time, propelled by its expanding economy, highly skilled labor force, and policies that encourage investment. Nevertheless, maneuvering through the intricacies of Polish accounting can be a complicated task.

    Accounting in Poland is regulated by the Accounting Act and supervised by the Polish Financial Supervision Authority (PFSA), harmonized with International Financial Reporting Standards (IFRS), yet also contains national provisions. Businesses in Poland must keep accounting books in Polish and the Polish Zloty, which can be challenging for foreign entities. The PFSA ensures the transparency and security of Poland’s financial market by regulating financial institutions.

    Foreign businesses often face difficulties understanding Polish accounting and tax regulations, language barriers, and local business practices. Frequent changes in regulations require adaptability. Professional accounting services can help businesses navigate these complexities and ensure compliance with Polish accounting standards.
