Testimonials

SATISFIED CLIENTS

Hi Michael,

Thank you so much.

I do not think we would get the outcome as good as this without your help.

I would definitely put 5 stars google reviews for you😊

Kind regards

Jane

Thank you for the great outcome Michael Cranston

Thank you Waterhouse Tax Lawyers

I cannot recommend Waterhouse Lawyers highly enough. I am a tax agent and referred a client to the team at Waterhouse Lawyers who was in quite a bit of trouble after lodging numerous years of Income Tax returns very late but for good reason.

It was beyond me to try to tackle the issues we had with the ATO on our own. I was so relieved the first time I spoke with Tania, I just knew I could leave it in safe, capable hands. I was so confident after talking with her.

The staff handling everything communicated and updated us on the way and were a great support. We had an amazing outcome, but I knew they would achieve the result in the end, I just knew from the beginning.

You are all amazing there.

I hope not to use your services in future! But I am relaxed knowing there is a team out there that I can call on to assist any of my clients with the really big legal issues they have with the ATO.

Thank you all again. Thank you Tania. I hope we can keep in contact into the future.

Forever Grateful

Tania, I just wanted to say a huge THANK YOU for all you have done.

An ATO audit that was turning very ugly, thanks to an extremely uncooperative accountant, has now had an excellent result! I knew I needed professional help and finding you through an internet search was a godsend. You were able to turn this horrible situation around and knowing I had you in my corner, helped put my mind at ease.

Now today you’ve told me it’s all over, the review is complete and we’ve had a great success – what a relief. I can now breathe and refocus on my business.

Thank you Tania – you’re a star and I wouldn’t hesitate recommending you and your firm.

Jennifer P—November 2015

Frustrated with the ATO one size fits all approach and the original law firm that I chose’s approach to not wanting to upset the ATO, I came to Waterhouse on recommendation.
Lucky for me, Tania and Charm were in the job the next day, grab all the information, dissected it, got to the central issue and started work in a proactive and informative manner.
Told immediately that if the case had no merit they would look to settle or take a stronger proactive stance.
It took some time and work, but success followed and very grateful to Tania and Charm.
Thank you

Grateful to Tania and Charm

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!
