Managing tax risk is a significant concern for all businesses operating in Australia. The ATO is reviewing companies and individuals with greater sophistication and rigour than ever before, including before commencement of any specific audit or investigation, and the State revenue offices have significantly increased their compliance activities.

Knowing the strength of your legal position and being prepared for what has become inevitable scrutiny from tax authorities allows you to plan the best course of action.

Experience dealing with ATO and the state revenue offices

Our knowledge of tax authorities' processes for identifying and managing tax disputes, as well as our effective communication with the ATO and the State revenue offices, give us an edge when it comes to resolving taxation disputes.

Negotiating successful outcomes

We have consistently negotiated successful outcomes for our clients. We understand that a negotiated outcome can often be in the best interest of our clients.

Experience managing tax litigation

Our team has managed large, complex tax litigation matters against the ATO and State revenue offices. We have acted for clients across all industries and on all aspects of tax litigation in the High Court, the Federal Court, State and Territory Supreme Courts, and in the Administrative Appeals Tribunal and the state administrative tribunals.
