In-depth knowledge of tax residency and other tax issues

Dear Tania,

Just want to say a big thank you, coming from a financial background myself, I was so impressed by your in-depth knowledge on tax residency and other tax issues, these are areas I often find that lots of accountants don’t even have an answer for, you are so knowledgeable, helpful, and really put my mind at ease.

Lourdes W—July 2018

Thanks for ATO tax advice

Dear Tania, thanks for your help. You have been instrumental in keeping my spirits high these past few weeks as the ATO enquiry was one of many issues I had to deal with at present.

When it comes to tax correspondence and official dealings with the ATO the usual anecdote is always to seek expert advice, but advice given is only one part of the story. The personable approach, understanding of your clients’ pain points and delivering on that developed empathy is many times more valuable in effect than perhaps the advice itself.

You aced that approach when dealing with my situation, understood my story and went far beyond the mile or service benchmark that I would normally expect any professional consultant would go to.

So, in that regards, I unreservedly am happy to recommend you to any contact I know who wants to get the right advice and in a way that he or she are also satisfied with the interaction.
