Testimonials

SATISFIED CLIENTS

I highly recommend Waterhouse Tax Lawyers to anyone who has an issue with the ATO. The team were all fantastic and particularly Tania Waterhouse – she is a life saver! My wife and I had what we perceived to be a huge problem with our SMSF – after speaking to Tania we engaged her to take over and communicate with the ATO on our behalf and the end result was way beyond our hopes. We can’t thank you enough Tania – you have made our year! Best wishes and eternal thanks from Tony and Alison.

Tania Waterhouse – she is a life saver!

Dear Tania

I want to thank you for responding so promptly to my request for assistance and thank you so much for assigning Lamees to look after our case.

She has been so very good to work with, I appreciate her skill at listening closely and understanding the specific details very quickly. She has assisted me personally by very gently managing my anxiety over this problem – by staying in touch and updating whenever possible.

We are of course hoping for a good outcome, but regardless of this it is comforting to know that she has a firm grasp of the issue and is dealing with it professionally and with sensitivity.

Kindest Regards

Help with DPN, tax debt

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

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.

Keith T—May 2018

Forever Grateful

Tania, I just wanted to say a huge THANK YOU for all you have done.

An ATO audit that was turning very ugly, thanks to an extremely uncooperative accountant, has now had an excellent result! I knew I needed professional help and finding you through an internet search was a godsend. You were able to turn this horrible situation around and knowing I had you in my corner, helped put my mind at ease.

Now today you’ve told me it’s all over, the review is complete and we’ve had a great success – what a relief. I can now breathe and refocus on my business.

Thank you Tania – you’re a star and I wouldn’t hesitate recommending you and your firm.
