Tax Disputes — Audits, Objections, Litigation

Dealing with the Australian Taxation Office (ATO) or State Revenue Office (SRO) can be stressful, time-consuming, and confusing. If you’re facing an audit, a penalty, or a dispute, it’s important to get clear advice and strong tax legal representation as early as possible.

At Mathews Tax Lawyers, our sole focus is Australian Federal and State tax law. We act for individuals and businesses who need help managing tax disputes with the ATO and SRO or who require tax legal representation to challenge ATO or SRO assessments and decisions in the relevant tribunal or court.

Why Early Advice Matters

Tax disputes rarely resolve themselves. The longer you wait, the more interest may build, and the fewer options you may have available to you. Getting tax legal advice early helps you to understand your rights and options, reduces unnecessary stress, and puts you in control of the process.

Our Approach

Clear Communication

We explain your options in plain English.

Direct Representation

We handle correspondence and negotiations with the ATO and SRO, so you don’t have to.

Experience

With over 30 years in tax law, including work at the highest levels of the ATO in Complex Advising, the Tax Counsel Network, and objections and litigation, at Big 4 firms in tax controversy and as a tax barrister, we bring deep insight into how tax disputes are managed and resolved.

Tailored Strategy

Every dispute is different; we develop an approach based on your circumstances and objectives.

Who We Act For

Next Steps

If you have received notification of an audit or review from the ATO or SRO, or are already in the middle of a tax dispute, don’t ignore it. The sooner you act, the more options you may have

I engaged Mathews Tax Lawyers after finding them through a Google search, seeking advice on a company tax matter following initial contact with a local firm. From the outset, the experience was seamless and highly professional. I was able to speak directly with the principal lawyer, Mark Mathews, who took the time to understand my situation, explained the process clearly, and provided an indicative fee on the spot. His depth of knowledge and clarity gave me immediate confidence to proceed. After I provided a detailed summary of the facts and requested a formal quote and timelines, he responded promptly—on the same day—with a clear fixed fee and practical guidance. Importantly, he advised that additional steps (such as further reports or rulings) were unnecessary at this stage, which reinforced my trust in his integrity and expertise. He initially indicated that the written advice would be provided within five working days. In fact, I received a comprehensive, well-reasoned legal opinion within just three days. The analysis was thorough, precise, and directly addressed the key issue, giving me a high level of confidence in proceeding. I am extremely satisfied with the service and would have no hesitation in recommending Mathews Tax Lawyers to individuals or companies seeking expert, efficient, and commercially sound tax advice.

Mark was exceptional to deal with from start to finish. He was professional, efficient, and always quick to respond, which made the whole process feel easy and well managed. What really stood out was how clearly he explained everything along the way. He took the time to make sure I understood each step, and it was obvious he has a deep knowledge of what he does. I’d highly recommend Mark to anyone looking for someone reliable and easy to work with. Thanks again Mark, I really appreciate your help.

I own an accounting firm and recently had the pleasure of dealing with Mark on a client matter. I had been speaking with another legal practice who simply didn't do what they had promised and was referred to Mathews Tax Lawyers. Mark was very efficient and pleasant to deal with, as well as providing the exact information we required. Would highly recommend thank you for your help.

There has been two ocassions now that I've spoken to Mark to see what I should do about a situation, each time he's spent 15 minutes or so giving me a direction or whether he can help with things. I've never had a laywer before but Mark was just someone that just seems to legimately care about his clients instead of making a quick buck from them. It appears that I'm not the only person who has this view reading the past comments. There's certain things outside of Mark's control obviously but it feels good when you have someone who you feel is on your side.

After submitting a brief online enquiry, I promptly received a call from Mark, who was already well-informed about my specific situation. He took the time to explain everything clearly and thoroughly over the phone. Mark was incredibly friendly, never tried to upsell unnecessary services, and provided honest, helpful advice free of charge. I’m truly grateful for his support—thank you!

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.

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.

I would highly recommend Mark to others. Although our case did not align with their business focus, Mark still took the time to thoroughly explain things to us and provided valuable advice that was undoubtedly helpful. We truly appreciate his professionalism, expertise, and patience.
