Tax residency thank you

Dear Tania and team

I came to learn of my tax issues when I returned to Australia after having been working and living overseas. I had no prior communication with ATO so this matter took me by complete surprise. The internet was my first call and when I saw Waterhouse Lawyers I was immediately struck by their credibility that told me I had come to the right place.

From the very first enquiry Waterhouse Lawyer’s expertise on tax residence, experience and professionalism were simply impressive. Communication with Tania, Keerti and Amanda were focused and kind. With the ATO’s final positive decision all the charges and interests amounting to $107,000 were completely cleared. I am exceedingly grateful to Tania and her team and will gladly recommend Waterhouse Lawyers to anyone with tax issues.

Thank you so very much

John T—July 2020

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!

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
