Mark Konza
Consultant, Sydney
Previously a Deputy Commissioner at the Australian Taxation Office for almost 20 years, serving as a Deputy Commissioner Public Groups and International for the last 10 years, bringing decades of ATO expertise to local and cross-border clients. I provide unique insights into the emerging tax risk governance space and advise clients on how to navigate complex engagements with the ATO.

My goal is to help our clients achieve the best possible commercial outcomes with their ATO dealings. I enjoy collaborating with our clients to ensure they are ATO ready, bringing important and unique perspectives to our clients on how to manage their ATO relationships with practical strategies to achieve outcomes on justified reviews, audits, tax ruling applications, and FIRB considerations.

My unique expertise spans tax technical and management roles across debt management, taxpayer assistance, assessments, rulings, disputes, and audits at various levels in large, small and medium business and individual tax segments

During my time as a Deputy Commissioner of Taxation, I was in charge of the Individual, Small and Medium enterprises, High Net Wealth, and Large Business taxpayer segments. With the emergence of the OECD's Base Erosion and Profit Shifting Action Plan, I became responsible for International Taxation and Competent Authority and led the ATO’s response to the BEPS Action Plan. In this role I led the establishment and operation of the ATO's Tax Avoidance Taskforce and was instrumental in the development and implementation of the revised transfer pricing provisions, the Multinational Anti-Avoidance Legislation, Country by Country Reporting, the Common Reporting Standard, and the Diverted Profits Tax.
