Tax behaviour is now a major feature of corporate reputation with instant communication putting intense pressure on international companies to publish information on how they meet their tax obligations and manage tax risks.

Fiscal  transparency and fairness are key concepts not just for enterprises and individuals, but for the government and financial institutions who compete to promote and attract international trade and investment. The G20/OECD project to tackle base erosion and profit shifting – BEPS - has brought together over 135 countries in a collaborative effort to combat tax avoidance, with a key focus on digitalisation.

Whatever your opportunities or challenges may be, our team is specially designed to understand your business needs and advises companies on how to comply with tax law.

We can help you shape your strategy, manage risks and make the most of business opportunities in these areas:

  • Excise Duties & Custom Duties
  • Family Estate Planning
  • Audit, Litigation and Criminal Tax Law
  • Direct Taxes - individuals and corporate income taxes
  • Energy &Tax 
  • Cross-border tax advice
  • ESG & Taxes
  • Indirect Taxes -including VAT, Stamp Duty
  • International & European Taxation
  • Real Estate Taxes
  • Transfer Pricing 
  • Digital Taxation

We have an in-depth knowledge of how tax law applies in practice across different markets and with cross-disciplinary teams, we work to provide advice close to our clients’ needs.
