Testimonials

SATISFIED CLIENTS

Never thought I could find help like that

Hi Tania,

I appreciate tremendously the advice and reassurance you gave me when I saw you . I never thought I could find help like that from anyone.

It was a pleasure meeting you and your staff.

Rita B—December 2017

Tania and her team supported me through a really difficult time dealing with the ATO following a long illness. Tania was able to ensure that I was remitted the full amount of general interest charges that had been imposed by the ATO, in circumstances when my initial request for remission had been rejected with seemingly no proper consideration or good reason. The entire team were so supportive throughout. Without her support, I may not have proceeded to push for remission of the charges and, without her knowledge of the ATO and lobbying of relevant persons, I do not have confidence that my case would have been properly considered by the ATO the second time round. My heartfelt thanks to the entire team at Waterhouse Tax Lawyers.

Exceptional Service and Tax Knowledge

I am delighted with the results Tania has achieved in dealing with the Australian Taxation Office. My matter was complex.However, Tania was quick to understand the issues and able to prepare a strategy for my approval. Once I approved the strategy Tania immediately went to work and achieved a result my previous lawyers had not thought possible.

I believe Tania is a very intelligent and honest person. She has a great sense of intuition and a very commercial approach. She also has a sense of urgency and diplomacy found only in a rare few.

Tania takes a pragmatic approach to solutions. She has a very approachable manner and does not become intimidated by aggressive and complex situations.

I have no hesitation in recommending Tania to anyone needing assistance with their taxation matters.

Thank you

My kids, my wife and I, cannot thank you enough.

When we thought we had lost everything you gave us hope.

You are a kind, humble and competent lawyer.

You have such amazing caring quality, so honest and such a fighter.

We will never be able to repay you.

Jack C—August 2016

Thank you Pious for today. Both you and Michael were excellent in the meeting with ATO. As a matter of fact everyone at Waterhouse Tax Lawyers I have dealt with has been outstanding in making sense of all this.
