Deloitte Tax Controversy Services

Broad-based, scalable, tailored for each client

Deloitte Tax Controversy Services provide assistance spanning the various stages of IRS, state, and local examinations, from dispute avoidance to issue resolution and post-exam improvements. Through decades of working with clients on a broad range of tax issues, we have fine-tuned our technology, analytical procedures, and planning methodologies to offer a broad-based, scalable solution that we can tailor to the specific circumstances of each client and each tax controversy.

What to expect from Deloitte Tax Controversy Services

Every tax controversy is unique; almost all are urgent and inconvenient. Precisely for these reasons, Deloitte Tax Controversy Services provides a team and a solution tailored specifically to each client’s controversy, drawing from our network of highly experienced, knowledgeable specialists from diverse backgrounds—former senior IRS and state executives, chief counsel officials, federal and state litigators, auditors, private industry tax executives, and technology specialists. Given the depth and breadth of experienced individuals on our team, we can ramp up and move quickly with the skills, processes, and well-established business relationships to expediently bring about a satisfactory solution.

Our close working relationships, credibility, and familiarity with tax agency teams and decision makers across the country enables us to quickly assess a situation, establish a tailored solution, and work efficiently with the
appropriate agencies. We also understand the importance of key internal communications and can help tax professionals keep executives informed throughout the process, from explaining the controversy to outlining the resolution and protections established to limit future controversies.

Our deep understanding of tax controversy, strong credibility and working relationships with tax agencies, and “in the trenches” knowledge of what it takes to avoid, manage, and learn from the various types of tax disputes translates to value to our clients in the following ways.
