Thanks for the reply. I think I need to file a tax return... does anyone here do this? Damn, I would rather be an FR and be taxed 0%-10% than have to deal with this.
Foreign Residents are taxed even higher: 30%. People who are a Australian resident for tax purposes are tax free for the first $6000 they earn every financial year, and between $6,001 - $37,000 its 15% as the starting rate. What made you think foreign residents are taxed lower compared with Australian residents?
All international students are considered Australian residents for tax purposes, as long as they have applied for a Tax File Number (TFN). If you do not provide your TFN to your bank/employer, they are obliged to withhold 45%, the maximum tax rate of what you earn.
This means if you do not give your bank your TFR, 45% of any interest you earn will be withheld. Similar with employment. Everyone who is in Australia needs a TFN. And you can apply for one from the ATO.
You only need to file a tax return if you have tax withheld from you. Usually there will be a PAYG slip given to you detailing how much of your income was withheld. You can file your tax returns online, and usually any refunds will be paid to you within 2 weeks. Paper tax returns take longer.
I know the tax return forms can be intimidating. Which is why I recommend that people use the e-Tax filing, which has build-in checks to ensure your file them correctly (as much as possible). See also the extremely helpful introduction on the front page by member Caspersky.
My only gripe with e-Tax is that it is a Windows application. It is useless under WINE, and Mac users have to bootcamp just to file their tax returns.
If you do provide your TFN to your bank, you only pay tax on interest if your interest has returns of >$500/month.
