Successful residency objection – grateful to Waterhouse Lawyers

What a relief! I am thrilled with the ATO residency decision that I was a non-resident when I was working overseas.

And have you to thank for the amazing support, care and professionalism in every aspect of my case.

I have no doubt I have chosen the right lawyer for my needs and am very grateful for your expertise and diligence.

GIC remission relief

That is such wonderful news about the remission of my GIC.

My tax predicament and trying to sort it all out has been rather worrying. I had managed to get myself in quite a state over it all.

But now light at the end of the tunnel.

I can’t thank you, Tania and your office enough for calmly and reassuringly guiding me through the process.

Thank you for taking on my case and thank you for the result – the sun is shining again.

Gobsmacked – unbelievable client service from tax lawyer

Can I please just say how gobsmacked I was that you would make yourself available for a client, let alone a new client on a Sunday. Unbelievable client service.!!!! .That is above and beyond service. You certainly are what your website promotes. Thank you.

Shane B—April 2018

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.
