Testimonials

SATISFIED CLIENTS

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

Some sanity returns to my life

For many years I have lived overseas and paid tax in my country of family residence and employment. You can imagine my surprise when I received a letter from ATO suggesting I might owe a return for the past 2 years including a list of overseas income. Alarm bells rang as I did indeed owe some returns, but fixing the issue opened a whole Pandora’s Box of issues that I knew could only be solved by a professional expert in Taxation Law.

I trolled the Internet for hours looking for a Tax Lawyer in my home city, most of whom were from very big firms. When I came upon Waterhouse Lawyers I immediately felt that I had found the right people even though we were miles apart. I engaged Tania and her team without a moment’s hesitation and was on board as a client minutes after discussion with one of her team.

Tania and her team have exceeded my expectations in all respects. At last I can sleep at night and find speaking to them a bright spot in my day. They quickly put me at ease by breaking down my issues into separate parts and providing solutions for each. Their honesty and really profession approach to client interactions is enhanced with their ability to make you feel that they are part of your family and really do care about outcomes that are in your best interest rather than feeding the corporate revenue stream.

I unreservedly commend Tania and her team to anyone with a Tax related issue.

Philip K—November 2015

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

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.

Melissa P—November 2018

A million thanks for a great result

Well thank you God & thank you Tania! I’m so grateful to you for your advice and for the time and care taken in the delivery so I could trust you and follow that advice. A very happy Christmas to you and many blessings as you have given me the best gift I could hope for.Lauren
