You’ve turned everything around for my daughters and I, after a very difficult couple of years

Mission Impossible Achieved

Tania, You were referred to me after a relentless three year audit of my taxation affairs by the ATO. As well as threatening my means of livelihood, the audit caused enormous personal stress. But you achieved the impossible and liaised with the ATO to obtain an unbelievable result. I am so grateful to you.

As a result of your fantastic efforts I am now free to get on with my life. Thank you so much.

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

Dear Tania and the Team,

I can’t thank you enough for your meticulous work and dedication. You’ve once again achieved an outstanding result, and I’m truly grateful. Taking on the ATO twice on my behalf-and succeeding both times- speaks volumes about your professionalism and remarkable expertise. It means a great deal to have such a capable caring, and determined team looking out for me. Thank you for the expert and personal care you have shown throughout.

With Heartfelt thanks,

Outstanding result in tax audit

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.
