Testimonials

SATISFIED CLIENTS

Grateful for tax advice

I am grateful to Tania who has offered her assistance.

Tanis’s free of cost consultation has proved that ‘yes ‘there are human beings who helped others in this materialistic world.

No wonder Tania you are highly professional and very kind hearted individual. My entire family is grateful to you. My words are not scripted it’s a real time experience of ordinary individual who is not representing any corporation or business enterprise.

Keith T—May 2018

ATO Tax Debt

Just when I thought there was no way to clear my ATO debt, Tania was there to negotiate on my behalf in a professional upfront honest caring manner. You are an Angel. Because of Tania, we are able to keep our family home, and have a life again free of the stress we had been suffering trying to clear a large debt.

Thank you sincerely Tania!

I would highly recommend Tania Waterhouse to anyone that has any form of debt to the ATO. Tania knows how to address an issue, and keeps you informed along the way. We can’t thank you enough on the professional guidance you provided based on your knowledge on taxation law, and what we can and can’t do. Once again, thank you!

Alex V—March 2019

Responsive, knowledgeable tax advice

I searched for a long time for responsive, knowledgeable tax advice. I finally found it with Waterhouse Lawyers.

I had very technical matters to address, and Tania Waterhouse invested many more hours than I paid for, and successfully resolved the issues. I am very happy with the outcome.

Equally valuable was the personal touch Tania brought to our interactions. I will use Waterhouse Lawyers’ services for all my future needs.

I unreservedly recommend them for any taxation matters.

Reid M—July 2016

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

Integrity shines

I would like to thank you once again for being so honest and fair with me and I very much appreciate your gesture to reduce your fees.

I would certainly recommend you to anyone looking for a good lawyer and one with integrity.
