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

Impressed with Waterhouse Lawyers and their swift response to our enquiry. Could not get a better pick in Michael with his experience and knowledge. Thank you both!

Saving my life and company

Hello Tania,

I hope this note finds you well.

You may or may not recall our case.

I will keep this short, as I can imagine you are very busy, but wanted to update you of the outcome. After you went into bat for me against the ATO in 2018, due to them issuing a garnishee over the company leaving me nowhere to go.
With your persistence we reached an agreement…saving my life and my company!

In our last conversation you asked me to let you know how we ended up and told me “show them that we would make it”!

Today I am emailing you with an enormous smile on my face…our ATO Super Guarantee Account debt was finalised in August, 2020 and today we received the attached statement from the ATO…as of 8th December, 2020 this is also finalised.
It has not been an easy journey, especially with the additional challenges of COVID…but we survived!

Thankyou Tania from the bottom of my heart, as without you I would not be sitting here typing this email.
May I wish you, your family and colleagues a very Merry Christmas and a safe New Year.

Warm Regards,

Trisha F

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.
