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

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.

GIC remission success

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.

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.

Tax residency thank you

Dear Tania and team

I came to learn of my tax issues when I returned to Australia after having been working and living overseas. I had no prior communication with ATO so this matter took me by complete surprise. The internet was my first call and when I saw Waterhouse Lawyers I was immediately struck by their credibility that told me I had come to the right place.

From the very first enquiry Waterhouse Lawyer’s expertise on tax residence, experience and professionalism were simply impressive. Communication with Tania, Keerti and Amanda were focused and kind. With the ATO’s final positive decision all the charges and interests amounting to $107,000 were completely cleared. I am exceedingly grateful to Tania and her team and will gladly recommend Waterhouse Lawyers to anyone with tax issues.

Thank you so very much
