Self-assess your liability

Employers who self-assess their liability monthly must pay payroll tax by the seventh day, or the next business day, of the following month. Review the payroll tax thresholds and rates.

You must submit your wage details each month using our online system PTX Express even if you do not have a payroll tax liability for a particular month.

You must use PTX Express to lodge monthly and annual reconciliation returns and pay securely.

If you are not already registered for payroll tax purposes and your wages exceed the threshold for any month, please complete an application to register for PTX Express.

2. Pay your liability

   Payment options are displayed once you have lodged your monthly return. A unique reference number is supplied with each monthly return so you can allocate payment correctly.

   Important notes

   If a previously lodged monthly return is incorrect, you can lodge a replacement monthly return that will override the incorrect return. Log in to PTX Express, navigate to lodge a monthly return and select the relevant return period, for example 1 January-31 January. Follow the instructions to enter your correct wage details.

   If you have overpaid payroll tax, you can also claim a refund for a previous monthly return via PTX Express. Log in to PTX Express and select to apply for a refund.

   Alternatively, you can contact us and ask to have the overpaid amount offset to a future monthly or annual liability.
