Hi Unni Menon,
You would be looking at reviewing the decision of the ATO. This would be an administrative review, not really a court action, and would be heard in the Administrative Appeals Tribunal.
As for how to go about starting the review, read
"Applying for a review" and
"Steps in a review".
It is possible to appear before the AAT without a lawyer. However, I would not recommend it. Taxation law is notorious for being one of the most difficult areas of law (this is why taxation lawyers are generally paid higher than lawyers in other practices). On top of this, you will need to understand administrative law, which is the particular avenue for challenging decisions made by government institutions. Administrative law is also quite complex. While you may believe your arguments make sense, a judge may not be as persuaded as they may not "hit" the legal grounds for a challenge. This is why I suggest you
see a lawyer, even if you just to talk to them about the general merits of your case.
I am not familiar with the costs of a review at the AAT. The best place to find this out is by browsing the AAT website or
call them up and ask.
As I wrote in my previous post, there are two tests you need to meet before you get "non-residency" status:
- You do not ordinarily reside in Australia (this is generally satisfied if you tick off the 6 month criterion); AND
- You have established a permanent place abode during this time (meaning, you have no intention of returning to Australia to live).
If you do want to challenge the ATO, I would suggest you read the following cases to familiarise yourself with previous rulings by the AAT and why they came to their decisions:
If you're self-representing, you will need to argue why your case is principally different from the first three cases and more alike the last. If you had a lawyer to advise you, this process would be a whole lot easier.
