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

So very Grateful. Five Star Service in tax matter

After 13 years of not being aware of it, the ATO advised me of an issue… a financially crippling, life changing kind of issue. Their timing was exceptional, with massive cutbacks at work, my employment future was uncertain, and a wife currently going through IVF the additional stress was almost unbearable.

I spent almost 6 months attempting to obtain the information I needed from the ATO with very little success.

In desperation I contacted Tania, and within a day of engaging her services she had cut to the core of the problem, obtained the information I had not been able to and explained clearly to me what the situation was. Within a week she had investigated the options available to me, identified a recommended course of action and put me contact with the relevant people to assist.

Tania was extremely professional and empathetic, kept me updated constantly on her progress and achieved a favourable outcome. My wife and I are so very grateful and it is an enormous relief to be able to put this behind us.

I would highly recommend Tania to anyone having tax issues of any kind.

Arran B—July 2015

Frustrated with the ATO one size fits all approach and the original law firm that I chose’s approach to not wanting to upset the ATO, I came to Waterhouse on recommendation.
Lucky for me, Tania and Charm were in the job the next day, grab all the information, dissected it, got to the central issue and started work in a proactive and informative manner.
Told immediately that if the case had no merit they would look to settle or take a stronger proactive stance.
It took some time and work, but success followed and very grateful to Tania and Charm.
Thank you

Grateful to Tania and Charm

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
