Tax controversy and dispute resolution

Taxpayers are facing the most challenging tax environment in history – this requires a full spectrum of disciplines to enable proactive and strategic approaches to tax audit and dispute prevention, management, and resolution.

The driving themes in today’s global tax landscape include enhanced tax transparency, tax efficiency, and improved tax dispute resolution mechanisms, driven in part by the OECD’s base erosion and profit shifting initiatives. In this global tax environment, taxpayers are faced with a number of new challenges that are in turn creating increased uncertainty.

The source of these challenges is primarily attributable to enhanced enforcement actions by tax administrations to increase revenues and address budget gaps. These actions are focused on engaging in aggressive audit and examination tactics, implementing unilateral measures that diverge from international standards, promulgating transparent reporting requirements, and developing robust risk assessment tools. As a result, there has been a substantial increase in the number and size of tax audits and disputes worldwide, placing further strain on the resolution of treaty-related disputes and increasing the risk of double taxation.

Greater risk and uncertainty causes taxpayers to re-evaluate their approach to proactively prepare for and resolve tax audits and disputes. This necessarily requires a multidisciplinary approach that utilizes tax and legal service providers with a global reach that are highly credentialed and well equipped to appropriately assist taxpayers in all phases of the tax dispute and controversy lifecycle.
