Testimonials

SATISFIED CLIENTS

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.

Thank you for A++ help

Very fortunate to find her

Tania, thank you sincerely for the result you have achieved with the ATO who carried out an audit on my 2002 return (in 2014!). This was an incredibly stressful time with no records, living in another country and an accountant who was very unhelpful.

You have achieved an amazing result, one which I could not have achieved without your professional help. My final ATO account was a mere 1.3% of the original ATO invoice. Now I can resume a normal life.

Sincerely,

Jasmine

Thank you from the bottom of our hearts: tax debt

Hi Lamees,

Thank you for helping to get our GIC remitted on our tax debt. What a successful outcome.

You have been wonderfully helpful and empathetic through this whole stressful tax debt process. I really don’t know how we would have managed without you!

Kindest Regards

Joan

Grateful for tax advice

I am grateful to Tania who has offered her assistance.

Tanis’s free of cost consultation has proved that ‘yes ‘there are human beings who helped others in this materialistic world.

No wonder Tania you are highly professional and very kind hearted individual. My entire family is grateful to you. My words are not scripted it’s a real time experience of ordinary individual who is not representing any corporation or business enterprise.
