Important notes on STP Prefilling of W1 and W2 in the ATO Portal Electronic Business Activity Statement
Attaché Payroll is the source of truth for ALL reported payroll data. Employers should compare their ATO PAYG Withholding Prefill to their Attaché Payroll records and correct any incorrect information accordingly.
The ATO allows for the CORRECTION of STP information if the information does not prefill correctly from your Digital Software Provider due to unforeseen reasons.
Employers are allowed to correct W1 and W2 period totals if what has been reported if it does not match, or STP Payroll batch information has not pre-filled correctly.
How to check your STP Prefilled values in the ATO Portal Electronic Activity Statement
If the ATO PAYGW Prefill does not match your records
To make sure your STP reporting is up to date, and you’ve submitted all the STP batches to date. See: Submit Single Touch Payroll batches that are in Ready to Submit status but get message A previous batch is unconfirmed.
Check the Gross figure in Attache excludes after tax Allowances and before tax Deductions. See: Gross on the Pay Totals Report does not match the Single Touch Payroll Batch Total.
If you need to correct W1 and W2 period totals
To correct the pre-fill amounts at labels W1 and W2 in the Activity Statement to match your payroll records, see: Correcting information reported through STP | Australian Taxation Office (ato.gov.au).
Complete W3 and W4 if applicable.
