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

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

Thank you very much for helping us through the difficult period during the first half of this year. Michael’s proposal for a settlement with the ATO was fair, practical, and highly effective.

We are very pleased with the outcome — it allows us to refocus on our business and continue contributing more tax to the ATO.

A true win-win-win for all parties.

Thank you for arranging settlement with ATO

Wish we had found you earlier

Thank you so much for your help. I just wish we had found you two years ago when we first starting having problems with the Tax Office.

Maria M—February 2015

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.
