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.
