How the PAYG instalment amount is calculated

The PAYG instalment amount printed at box T7 on your activity statement or instalment notice is based on the income tax that would be payable on your business and investment income (excluding any capital gains) from your most recent income tax return.

When working out the instalment amount, we apply the GDP adjustment to this business and investment income – this takes into account likely changes to your income since the year of that income tax return.


Your PAYG instalment amounts may change during the year if you vary your instalment amount or lodge an income tax return.
