Answer
In STP Phase 2, an Update Event refreshes each employee’s year to date (YTD) details only. It does not report the company level pay run totals for W1 (Gross) and W2 (PAYG Tax Withheld) that are used for BAS/PAYG pre fill. As a result, the ATO portal will show $0.00 for gross and tax on an Update Event. This is normal, expected behaviour and part of STP design.
- Affects W1/W2 totals: Pay Events (new events) and Adjust Events.
- Does not affect W1/W2 totals: Update Events (they adjust employee YTD figures only). Click View in the Single Touch mailbox to see individual employee amounts within an Update Event submission.
If you need to change BAS pre fill amounts, send an Adjust Event or lodge any unsubmitted Pay Events.
