Hi @sammy1991
It sounds like you have been checking the status of your return before it has been finalised. So you will have noticed the different total in our balancing accounts as your return has passed through the various stages of processing.
I can't tell you exactly why you have ended up with a tax debt when you were expecting a credit. There are multiple reasons why this can happen. One area I'd suggest you check on your return is the Medicare Levy Surcharge. If your individual or combined family income increased above the threshold for the MLS exemption and you don't have an appropriate private health insurance policy then you will be charged an additional medicare levy surcharge. This is something that employers are unable to take into account when they withhold PAYG tax on your behalf.
We have an informative knowledge base article here which explains the various stages of the tax return.
You can also read more about the Medicare levy surcharge online here.
I hope that helps.
@SPezza, the income tax return summary is found in our ATO Online services through MyGov.
