Our Team

Meet the team

Our tax team come from diverse backgrounds – from a former Deputy Commissioner of Taxation, to a former Mallesons solicitor. This enables us to provide comprehensive tax advice that considers tax issues from every angle and ensures that we achieve the best possible outcomes for you.


Tania Waterhouse LLB (Hons) LLM (Tax)

Partner - Former ATO Director

Tania began her legal career with Mallesons Stephen Jacques where she specialised in tax and superannuation.

She then joined AusIndustry as a litigator in the old R&D scheme.

She was then engaged as a Director at the ATO where she worked for almost a decade as a Director. During this time she acquired in-depth knowledge of international taxation, superannuation and tax litigation. Tania also developed close professional relationships with numerous senior staff and has maintained these relationships since leaving the ATO.

Tania used all of private and public sector legal experience to establish her own law firm. She now uses her specialist knowledge of taxation law to gain great results for most of her clients.

Clients are always impressed by Tania’s warm, open approach to their tax problems. After talking through their issues with her they always depart feeling greatly relieved to have Tania on their side.

Tania is also a professional florist. She owned her own florist for several years so she knows from personal experience the difficulties small business owners face trying to keep up with their tax obligations while trying to run a successful business. These days she only does arrangements for friends’ weddings.


Michael Cranston BCom (Accounting), MTax

Partner - Former ATO Deputy Commissioner

Michael has a Masters of Taxation from University of Sydney. In addition, he completed a Bachelor of Commerce majoring in Accounting. He is also a Fellow of the Tax Institute of Australia.

With over 40 years experience with the ATO, the last ten as Deputy Commissioner for Private Groups and Individuals, Michael understands the difficulties facing taxpayers with complex structures.

Michael’s strong mediation skills allow him to negotiate and achieve the best result possible for taxpayers.

In addition, Michael’s forensic accounting skills enable him to analyse complex accounting records in order to determine whether the ATO has made an error in their analysis of a taxpayer’s assessable income.

Waterhouse Lawyers has engaged Michael to provide accounting assistance and to assist in negotiations with the ATO. He is not a lawyer and does not provide legal advice which is provided by Tania Waterhouse.

Michael loves fishing and a beer with mates.
