What if you don't pay the right amount of income tax?

If you haven't paid enough

If you owe tax, and have received a personal tax summary or filed an individual income tax return, you must pay the amount owing by 7 February of the following year. We've made it really easy to meet your tax obligations - you can make tax payments electronically through your bank, by cheque or at most branches of Westpac.

If you don't pay the full amount of your tax on time, you are liable for any penalties that may apply - so it's best to make sure your tax is all paid up by the due date.

If you've paid too much

If you've paid too much tax or have received a tax credit (formerly rebate), and think you're entitled to a refund, you need to request a summary of earnings (SOE) and calculate your personal tax summary. If you then work out that you're due a refund, you can request a personal tax summary in order to receive the refund.
