As local and international tax rules become more prescriptive, and compliance and reporting obligations more onerous, dealing with them effectively is a significant challenge. Our UK-based tax team is well-placed to assist you. We are part of a 300 strong tax group across Europe and beyond. Supported by strong technical back-up teams that identify developments in tax law and policy affecting your business, we will help you develop robust structures that maximise tax effectiveness and can respond to future developments such as BEPS. We work with you to implement an appropriate tax strategy for your business.

Whether you are a financial institution, multinational, fund, corporate investor or high net worth individual, we understand your commercial drivers and the tax pressures you face.

Our teams work together across all sectors and all areas of tax affecting your business including VAT, transfer pricing, tax structuring and tax disputes. Where you are undertaking a transaction, our advice can make a material difference to transaction costs, help you exploit tax saving opportunities and, in some cases, avert serious consequences. If you are involved in a dispute, an early intervention with the tax authorities on your behalf can ensure the best outcome for your business.
