Tax

Latest

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 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 due to our global tax presence and our in-depth expertise in national tax laws.

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.

The Tax Team members in Hungary are also registered as tax advisors, and are top ranked by independent legal directories. The head of the department is an active member of the European VAT Club, an association of independent VAT specialists. The team advises on all areas of domestic and international tax law, social security payments and state subsidy issues as well as represents them in tax litigation matters.
