Single Touch Payroll Phase 2 makes payroll data more detailed and more useful to government agencies, but it also increases the importance of clean payroll setup. A Melbourne employer can lodge an STP file successfully and still have poor payroll controls if employee classifications, payment categories or year-to-date balances are wrong.
This TNS Accounting guide explains how to manage STP Phase 2 as part of a wider payroll process rather than treating lodgement as the final step.
What is STP Phase 2 and what does it report?
The ATO describes STP as the way employers report employee tax and super information. Phase 2 expands the detail reported, including how different payment types are classified. ATO STP guidance is the authoritative starting point.
What employee data should be checked before an STP pay event?
Review employee identity data, employment basis, income type, tax settings, super details and payroll classifications. New starters and employees with changed conditions deserve extra review because setup errors can flow into every later pay event.
How should allowances, overtime and leave be classified in STP Phase 2?
Different payment categories can require different reporting treatment. Payroll teams should map earnings codes deliberately rather than using a generic “other” category for convenience. The payroll code, payslip description, accounting treatment and STP classification should tell a consistent story.
How should an employer correct an STP error?
The correct method depends on the type of error and the payroll software. The ATO provides guidance on update events and corrections. Employers should fix the source data first, then submit the appropriate correction and confirm year-to-date figures are accurate.
Do not simply overwrite a number without understanding why the error occurred. A correction should also trigger a process review so the same issue does not repeat.
How should STP totals be reconciled with payroll and the general ledger?
Compare payroll year-to-date wages and PAYG withholding with the accounting ledger and payroll liability accounts. Differences can come from manual journals, duplicated entries, off-cycle payrolls or corrections that did not flow through accounting correctly.
Monthly reconciliation reduces the pressure at year-end finalisation and supports cleaner BAS workpapers.
How does STP connect with Payday Super in 2026?
STP reports payroll information while Payday Super governs when super contributions need to be paid. Employers should reconcile these processes because the ATO has increasing visibility over payroll and super data. Read the Payday Super 2026 guide for the payment side.
How should an employer prepare STP data before the first pay run of the year?
Review active employees, employment basis, income types, tax settings, payroll codes and year-to-date opening balances. Check that employees who have left are not accidentally included and that new starters have complete data. A short pre-year or pre-migration review is easier than correcting repeated errors later.
Where payroll software has been upgraded or migrated, compare several employee records against source documents and test a pay event before normal processing begins.
How should back pay, off-cycle payroll and corrections be handled in STP?
Off-cycle payments and back pay can create differences between the normal payroll calendar and STP year-to-date reporting. The employer should identify the payment type, use the correct payroll code and reporting treatment, and then reconcile the updated year-to-date totals. Do not create an ad-hoc code purely to make a payslip look right if its STP mapping is unknown.
If a correction changes PAYG withholding or super, check the related accounting liabilities as well. Reporting corrections should not leave the general ledger behind.
What should employers check before STP year-end finalisation?
Compare employee year-to-date wages, PAYG withholding and relevant payroll categories with payroll reports and accounting records. Review terminated employees, corrections, allowances and unusual balances. Confirm all expected pay events were accepted, then complete finalisation using current ATO guidance. Regular monthly reconciliation makes this year-end process much easier.
How should employers manage STP when employees work across different pay arrangements?
Businesses with salaried, casual, commission-based or variable-hours employees should confirm that each employee’s employment basis and payment categories are configured correctly. Avoid using one generic payroll code for different payment types simply because it is easier to process.
When a pay arrangement changes, update the employee record before the next pay event and check the resulting year-to-date figures. This is particularly important where an employee moves from casual to permanent work, receives a new allowance structure or starts salary sacrificing amounts that affect payroll reporting.
What should employers do if an STP submission is accepted but the totals still look wrong?
Reconcile the employee year-to-date figures to payroll reports and the ledger. Technical acceptance does not replace a financial review, so investigate the underlying data before the next pay event.
What are the most common STP Phase 2 questions from Melbourne employers?
Is STP Phase 2 separate from payroll software?
STP is generally reported through enabled payroll software or an approved reporting solution.
Should STP be checked every pay run?
Yes. Confirm the pay event was accepted and investigate exceptions promptly.
Can a successful lodgement still contain wrong data?
Yes. Technical acceptance does not guarantee that employee setup or classifications are correct.
What should be reconciled to STP?
Wages, PAYG withholding and relevant year-to-date payroll balances should be compared with payroll and accounting records.
Do allowances need separate classifications?
Many payment types require specific reporting treatment under STP Phase 2.
How are errors corrected?
Use the correction process supported by your payroll software and current ATO guidance.
Should the original error be documented?
Yes. Record the cause, correction and any control change introduced.
Does STP replace payslips?
No. Fair Work payslip requirements continue to apply.
Does STP prove super has been paid?
No. Reporting and actual fund receipt are separate issues.
When should STP be finalised?
Employers should follow current ATO year-end finalisation deadlines and procedures.
Can TNS Accounting help reconcile STP?
Yes. TNS Accounting can help review payroll reports, accounting balances and payroll workflows.
What if a manual journal changes wages expense?
Investigate whether the journal causes payroll and ledger totals to differ and document the reason.
Should old employee records be reviewed?
Yes, especially before finalisation or when migrating payroll systems.
What is the biggest STP control risk?
Incorrect recurring setup that appears in every pay event.
