Definition of terms

Definitions of the terms used in the Single Touch Payroll (STP) reporting guidelines.

Last updated 23 October 2026

STP is the way you report your employees' tax and super information to the ATO.

The following terms are used in these guidelines:

  • Digital service provider (DSP) – those who develop or deliver digital services that help taxpayers meet their tax and super obligations.
  • STP report or reporting – used as a term for a submission of any of the below
    • Pay event – the file generated by an STP-enabled software or solution. This file must be lodged to us on, or before, the payment date when an employer makes a payment to an employee or payee that is subject to withholding.
    • Update event – the service that allows an employer to transition within STP and correct or finalise STP data. Update events should not be used when employees receive payments subject to withholding.
    • Adjustment event – optional action that allows the employer to report corrections to employer (payer) period totals previously reported. An adjustment event will increase or decrease the employer-level gross payments amount (W1) and withholding figures (W2) for a PAYG withholding period. It does not adjust payee records.
  • Business Management Software ID (BMS ID) – uniquely identifies the source of employee data sent to us as a specific instance of payroll software.
  • Payee Payroll ID – a key identifier that represents each employee in the payroll that, in conjunction with payee details and the tax file number (TFN), enables us to uniquely identify the taxpayer.
  • Income statement – the equivalent of an employer-issued payment summary. It contains the latest year to date (YTD) STP data reported by employers. It's available through ATO online services accessed through MyGov. If an employee does not have a myGov account they can create a myGov account and link it to the ATO.
  • Finalise – a declaration made by an employer that the information for each employee is correct and complete for the financial year. This is done by providing the finalisation indicator as a part of an employee’s STP report.
