As local and international regulations become more prescriptive and enforcement gathers pace, dealing with the evolving tax landscape in a cross-border context presents you with a significant challenge. The number and complexity of tax investigations conducted by authorities is rapidly escalating and the need for tax adjustments is rising accordingly.

Our 350 tax lawyers worldwide are supported by strong technical tax intelligence teams that identify developments in tax law and policy affecting your business. This multi-disciplinary approach helps you develop robust structures that maximise tax effectiveness in alignment with your commercial strategy. Given the cross-border nature of today's tax issues, top corporates and financial institutions seek our advice in Central and Eastern Europe, given our global tax presence and our in-depth expertise in national tax laws.

I like the pro-business approach and creativity, and the lawyers always very quickly and very efficiently help us to solve problems. You can always rely on the team.

Chambers Europe

Whether you are a financial institution, multinational, fund, investor or high net worth individual, we understand your business and the tax pressures you face. Our teams work together across Central and Eastern Europe and beyond in the key areas affecting your business including VAT, international taxation, transfer pricing, e-commerce, M&A and investment funds, tax planning and financing. Our experts can help you manage tax control cases and deal with tax authorities as well as manage tax litigation cases, including challenging tax liability decisions. The right tax advice can make a material difference to transaction costs and, in some cases, avert serious consequences.

Our Polish team frequently advises on the creation of effective tax structures, restructuring of business entities, M&As and transfer prices. We specialise in international agreements on taxation of direct income, income from investments, as well as holdings and portfolio investments. We also provide advice on real estate tax, including tax on agricultural properties. We represent our clients before the tax authorities and administrative courts.
