Testimonials

SATISFIED CLIENTS

Tania and her team have been great with their advice and handling of my legal matters with the ATO and TPB.

Thank you Tania, Bernie, Alice, Coco and the others over the journey.

The legal advice has been A++, as was expected.

What was not expected was the caring and empathetic way the services was provided through the entire process. Legal matters are very stressful, and I felt that the Waterhouse team had my back along the way.

I really appreciate that Tania still checks in on me from time to time, even after the matter has been settled.

The Waterhouse team were supportive when needed, but also there was a good dose of reality when that was needed as well.

I certainly hope I will never need their services again, but I can sleep easier with the feeling I know where to go if I ever have another legal matter involving the ATO or TPB.

God bless to the Waterhouse team – my family’s future is safer and more secure by having you on my side.

Thank you for A++ help

In-depth knowledge of tax residency and other tax issues

Dear Tania,

Just want to say a big thank you, coming from a financial background myself, I was so impressed by your in-depth knowledge on tax residency and other tax issues, these are areas I often find that lots of accountants don’t even have an answer for, you are so knowledgeable, helpful, and really put my mind at ease.

Speedy, Efficient, Friendly

My experience with Tania has been nothing short of awesome. Her expertise, her experience, her speedy work, and her cheery and pragmatic approach has been instrumental in giving us the direction we needed with our case. Tania is a superstar and we love working with her.
