Demands around corporate tax compliance are increasingly complex in today’s changing regulatory environment.

There are growing regulatory and professional business risks for those companies who get it wrong. The revised penalty regime makes mistakes more costly with potentially higher penalties. Additionally, HMRC has adopted a more system-based approach to compliance rather than substantive review. With the enhanced focus on the tax compliance process companies need to ensure that their tax processes are robust, accurate, and reliable.

Thomson Reuters can help you address all these issues with Digita Corporation Tax Advanced software.
