E-tax is software made by the Australian Taxation Office (ATO) that enables Australian employers/employees and taxpayers to lodge their tax return online. Being a Windows program, it does not run natively on Ubuntu so you'll need to either use Wine or a VirtualBox set-up to run e-tax on Ubuntu.

You will need to grab the latest version of e-tax from the ATO's website - http://www.ato.gov.au/individuals/content.aspx?doc=/content/32234.htm&page=5&H5

The latest version of e-tax as of writing was e-tax 2011.

E-tax on Ubuntu using Wine

To use e-tax on Ubuntu, you'll need to install Wine. Wine can be use to run Windows programs on Ubuntu. To install Wine, either run:

sudo apt-get install wine

Or open up the Ubuntu Software Centre and search for Wine - it's in the universe repository. You'll be likely to have better success if you're using a recent version of Ubuntu, namely 10.10 or 11.04, due to the Wine version being much more current.

Once you have installed Wine, you should be able to open the .msi etax2011 file you downloaded by right-clicking it and selecting, "Open with Wine Windows Program Loader"

If Wine does not run the program properly, you can also try using the command -

msiexec /i etax2011_1.msi
