Testimonials

SATISFIED CLIENTS

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

In a time filled with emotional and stressful challenges, seeking advice from Tania Waterhouse was the best decision I could have made. Her guidance provided me with the clarity and confidence needed to navigate through my issues. She has a remarkable ability to ease one’s mind with her expertise and genuine support. I highly recommend Waterhouse Lawyers for anyone in need of legal guidance.

Michelle K – April 2024

When I was audited by the ATOI was given the wrong advice by my legal and accounting advisers. I was therefore left with a very unfavourable outcome and I had to object

I engaged the team at Waterhouse Lawyers for my audit objection and they were able to successfully reverse some very poor ATO decisions. I wish I had contacted Tania and team as soon as I received the original audit notice rather than trying to deal with the matter myself.

Unfortunately due to the original advice I had, the matter then progressed to something of a very serious nature. I contacted Tania and she very quickly returned my call and was able to give me advice at a time that was terrifying for me personally.

Tax Audit – Objection – grateful thanks

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.
