STP and activity statements

How we use Single Touch Payroll (STP) data to simplify employer reporting obligations.

Last updated 15 August 2025

Using STP data to prefill PAYG withholding in activity statements

Employers report pay as you go (PAYG) withholding via STP. We use that same data to help prepare activity statements – enabling employers to ‘tell us once’.

PAYG withholding labels W1 and W2 will be pre-filled in ATO online services using the information reported through STP.

For more information, see ATO PAYG withholding pre-fill for activity statements.

Activity statement lodgment reminders

Employers who don't lodge their activity statements on time may receive a lodgment reminder from us.

For more information, see Lodgment reminders.

On-demand activity statement lodgment report for agents

Agents acting on behalf of employers will be able to access an updated on-demand activity statement lodgment report to see:

  • which of their clients have been issued a reminder
  • the proposed next action and timing.

From July 2023, we'll use your STP reports to help prepare your electronic activity statements in ATO online services.

We send reminders if you haven't lodged your activity statement on time.
