If you have a concern about the way a tax law applies to your personal tax affairs, you may want to ask for a private ruling.
A private ruling will relate just to your situation. Write to the ATO describing your situation in detail and ask for advice. Include your tax file number. If you lodge your tax return before you receive your private ruling, be aware that the ruling may alter the accuracy of your tax return.
You can ask for a review of a private ruling decision if you disagree with it, even if you have not received your assessment. The ATO can give you more information about review procedures.
