Taxation Mediation


Helping you find your own solutions to disputes through mediation

Roger Hamilton SC is a highly experienced tax lawyer and a Senior Member of the NSW Civil and Administrative Tribunal where he heads the Revenue List*. 

For over 40 years Roger has specialised in litigating and advising in Revenue Law - including international taxation, Commonwealth and State taxes, superannuation and the structuring of the affairs of high net worth families. 


A mediator is an independent person appointed by the parties who guides them through a structured process (hopefully) to a resolution of their dispute by agreement.  

A mediated solution can avoid the cost, stress and uncertainty of a Court or Tribunal hearing.

Areas of Mediation Practice

income tax

Disputes between the Australian Taxation Office and taxpayers are often suitable for a mediated settlement, and the Tax Office has embraced alternative dispute resolution as a process to which it will commit in the right circumstances.

stamp duty, land tax, payroll tax

Roger has had wide experience of state tax matters covering jurisdictions other than NSW, and can only become involved in mediating disputes which do not involve Revenue NSW.

capital gains tax

Capital gains tax disputes are becoming more common and can often be resolved through mediation (for example in cases involving cost base, date of acquisition, use of property etc)


Roger has a strong understanding of superannuation issues and is well equipped to be engaged in seeking to settle disputes between members and super funds.

international tax

This is a particular interest of Roger's and in fact he co-wrote one of the leading texts - Understanding Australian International Taxation.


restructuring family investment vehicles 

Much of Roger's professional experience has involved structuring of various family investment vehicles, and advising on estate planning matters.
