We would highly recommend their services. Connect4U AustraliaPosted on Anne GrantTrustindex verifies that the original source of the review is Google. I selected Mark randomly from an internet search for tax advice and so was a little anxious. But I was very fortunate. I found Mark to be professional, but very approachable and kind. He quickly researched the matters I was concerned about, was knowledgeable and provided an immediate way forward. I can wholeheartedly recommend Mark to anyone looking for tax advice.Posted on George MTrustindex verifies that the original source of the review is Google. I am happy to engage Mark’s services above numerous other Tax Lawyers, as he actually demonstrated to me that he was a man of integrity that is considerate of his client's needs. So many firms publicize that they provide a “free initial consultation” to help assess your needs and determine how they can best help you. Rather than assessing your needs, the majority of them spend that time simply telling you their service costings instead. Despite not advertising for a “free initial consultation”, when I rang Mark he was the only one who was attentive to the details I explained regarding my case and even highlighted issues that were in my interest to focus on cost effectively without giving formal legal advice. What a refreshing change to my experience with numerous other Lawyers! Mark is the kind of person that I am looking for. He showed a sincere interest in my case and was considerate enough to care about my wellbeing with genuine professional integrity, which I greatly appreciated. I highly recommend Mark’s services for you to navigate the complexities of the ATO maze with caring support.Posted on Alex Yan AuroraTrustindex verifies that the original source of the review is Google.

Mark would respond to calls/emails in a timely manner and instilled confidence from start to finish.

Anonymous
“Very satisfied with the services that Mark provided for a tax related query that I approached him about, which my accountant did not know the answer to. I got 3 quotes from 3 different lawyers/firms and his was the most transparent. Turnaround was very fast (next day) and he was very responsive to all emails. He also provided raised some points that I did not specifically ask him about but which were related to my issue. Although I do hope I don’t ever have to deal with any lawyer in the future, I’ll be sure to approach Mark again if I need any legal advice on tax issues.”

Carl Spruce
“I received a tax ruling from the ATO which I wasn’t happy about. I engaged Mark’s firm to review the matter and advise me on the tax implications. Mark provided me with a detailed report setting out the reasons why I should not be paying ordinary income tax on a completed property project of mine.
Before I commissioned Mark I was anxious and concerned for a possible heavy tax burden but Mark has allayed these fears for me. I found his costs both reasonable and fair and had a pleasant surprise when I received a 30% rebate on his initial estimated fees. I would certainly recommend Mark to any who need professional and caring advice as that which was shown to me.”

To support this – I would welcome my recommendation of Mark’s services without any hesitation.”
