Payroll validation before EOFY means checking that the payroll data you’re about to finalise is actually correct — that pay rates, penalties, superannuation, leave balances, PAYG, and year-to-date totals all reconcile against source records — before you lodge your Single Touch Payroll finalisation declaration (due 14 July). Validate in a set order: reconcile the payroll register to the general ledger, review award rates and penalties, run an employee-by-employee check of YTD earnings, super and leave, then fix any discrepancies while they can still be corrected in the current financial year. Errors found after 30 June cost more to fix — amended finalisations, backpay across financial years, and penalty interest.
End of financial year is a critical checkpoint for Australian employers. Payment summaries, superannuation, BAS lodgements, and annual reporting all depend on accurate payroll data. Errors discovered by the ATO or Fair Work are worse still. This guide covers the validation processes to complete before 30 June — distinct from broader audit preparation, which is about assembling the evidence to withstand a review; validation is about proving the numbers themselves are right. With proper payroll integration, much of this validation can be automated and simplified.

- Timing:
Complete validation by mid-June, then finalise STP by 14 July
Validation vs audit preparation
These two EOFY jobs are related but different. Validation (this guide) confirms the payroll data is correct — rates, penalties, super, leave and YTD totals all reconcile. Audit preparation is about being ready to prove it — assembling timesheets, approvals, award interpretations and payment evidence so the numbers hold up under ATO or Fair Work scrutiny. Do the validation first; clean data makes audit preparation far simpler. See our companion guide on payroll audit preparation before EOFY.
Why EOFY validation matters
Investing time in pre-EOFY validation delivers significant benefits across compliance, cost, and reporting.
Avoid amended finalisations
Amended STP finalisations and BAS lodgements are time-consuming and create audit triggers. The ATO notices when employers file frequent amendments. Finding and fixing issues before you lodge your finalisation declaration means clean submissions the first time.
Prevent backpay obligations
Underpayments identified after EOFY become backpay obligations that span financial years. This complicates tax treatment, creates additional administrative work, and may trigger interest obligations. Catching underpayments now allows correction in the current period. Recurring underpayments usually trace back to payroll errors from bad timesheet data, so fix the source as well as the symptom.
Reduce audit risk
Both the ATO and Fair Work use data matching to identify potential compliance issues. Clean, accurate payroll data reduces the likelihood of being flagged for review. Demonstrable validation processes also help if you are audited.
Accurate financial reporting
Leave liabilities, accrued wages, and superannuation payable all affect financial statements. Validation ensures these figures are accurate for financial reporting purposes. Accountants appreciate clean data at year-end.
Key areas to validate
A comprehensive EOFY validation covers these critical areas:
Pay rate accuracy
Verify current pay rates match applicable awards or agreements. Check any rate changes during the year were applied from the correct effective date. Confirm casual loading is calculated correctly.
Penalty rate calculations
Validate that evening, night, weekend, and public holiday penalties were applied correctly. Check that penalty rate changes during the year were implemented accurately. Review a sample of high-penalty periods.
Superannuation
Confirm the correct super guarantee rate was used all year. Verify calculations on ordinary time earnings. Check quarterly payment compliance. Reconcile super payable to super paid.
Leave balances
Validate annual leave accrual rates match employment type. Confirm leave taken was deducted correctly. Check leave loading calculations. Review long service leave for eligible employees.
Overtime and allowances
Verify overtime was calculated at correct rates. Check that allowances were paid according to award requirements. Confirm meal breaks and rest periods were compensated correctly.
Tax and deductions
Validate PAYG withholding against tax tables. Check deductions were processed correctly. Verify tax file number declarations are current. Reconcile to BAS lodgements.
EOFY validation timeline
Start validation early to allow adequate time for investigation and correction. Rushing in the final week leads to missed issues:
April: initial reconciliations
Begin high-level reconciliations. Check payroll register totals against the general ledger. Identify any obvious discrepancies. Review year-to-date superannuation and PAYG against lodgements. This early check reveals major issues with time to investigate.
Early May: award compliance review
Review pay rates against current awards for all employee classifications. Check that any mid-year award increases were applied correctly. Validate penalty rate calculations for a sample of pay periods. Identify any potential underpayment issues.
Mid May: employee-level validation
Generate reports for each employee showing year-to-date earnings, super, leave balances, and PAYG. Validate against source records. This detailed review catches individual errors that aggregated checks miss.
Late May: issue investigation
Investigate any discrepancies identified. Determine root causes. Calculate correction amounts. Document findings and remediation plans. Prioritise corrections that must be processed before year-end.
Early June: process corrections
Process necessary adjustments while there’s still time — backpay for identified underpayments, leave balance corrections, and super true-ups. Communicate with affected employees. Document all corrections.
Mid June: final validation
Run final reconciliations after corrections. Confirm all issues have been addressed. Prepare for year-end processing. Brief the payroll team on EOFY procedures. Leave buffer time before 30 June for unexpected issues.
Don't stop at 30 June
Validation and lodgement are separate deadlines. Your data should be validated by mid-June, but your STP finalisation declaration is due to the ATO by 14 July. Use the window between the last pay run and 14 July to run a final year-to-date reconciliation, then finalise. If you correct anything after finalising, you must lodge an amended finalisation — another reason to get validation right the first time.
Superannuation validation checklist
Superannuation is a high-risk area requiring careful validation. Use this checklist to support compliance:
Correct rate applied
Verify the 12% super guarantee rate (from 1 July 2025) was used for all calculations. No mid-year rate changes apply — 12% has been the SG rate since 1 July 2025.
OTE calculated correctly
Confirm super was calculated on ordinary time earnings only (generally excluding overtime). Review any borderline payments for correct treatment.
Maximum base applied
For high earners, verify the maximum super contribution base was applied correctly. Super isn’t required on earnings above this quarterly cap.
All eligible employees included
Check that all eligible employees received super, including casuals and those under 18 working more than 30 hours per week. The $450 monthly threshold no longer applies.
Quarterly payments on time (2025-26)
For 2025-26, verify each quarterly super payment was lodged and received by the due date. Late payments attract the super guarantee charge including nominal interest and administration fees. Note: from 1 July 2026 the quarterly cycle is replaced by Payday Super — contributions must reach the employee’s fund within 7 business days of each pay run.
Payable reconciles to paid
Reconcile total super calculated against total super paid. Differences indicate calculation errors, missed payments, or timing issues requiring investigation.
Payday Super transition — validate the crossover carefully
The 2025-26 EOFY straddles a major change. Your April–June 2026 super is still under the quarterly cycle (Q4 payment due 28 July 2026), but from 1 July 2026 Payday Super begins — contributions must reach the fund within 7 business days of each pay run, and the Small Business Superannuation Clearing House closes. Validate that Q4 contributions are paid on time under the old rules, and confirm your fund and clearing-house setup is ready for the new same-cycle obligation before your first July pay run.
The core EOFY reconciliations
Validation isn’t just spot-checking individual pays — it’s confirming the totals tie out across your systems. These are the reconciliations that catch errors an employee-by-employee review misses. Run each one before you finalise:
Essential EOFY reconciliations and what a mismatch signals
| Reconciliation | What to match | A mismatch usually means |
|---|---|---|
| Payroll register to general ledger | Total gross wages, tax and super in payroll vs the GL | A journal posted wrongly or a pay run not captured |
| Super payable to super paid | Super calculated on OTE vs contributions remitted | Missed payment, wrong OTE setup, or timing |
| PAYG withholding to BAS | PAYG withheld in payroll vs amounts reported on activity statements | A pay event not lodged or a category mapped wrongly |
| Gross wages to STP finalisation | Year-to-date gross per employee vs the STP finalisation figures | A pay category excluded or salary sacrifice misclassified |
| Leave liability to leave balances | Accrued leave value in the GL vs balances in payroll | Accrual rate errors or unrecorded leave taken |
| Timesheet hours to payroll hours | Approved hours vs hours paid | A timesheet not imported or manually overridden |
A variance above a few dollars (allowing for rounding) on any line should be investigated before you finalise, not after.
If you run these reconciliations every pay period rather than only at year-end, small discrepancies get corrected while they’re still small. Our guide on reconciling payroll variances walks through the investigation process step by step, and the year-end reconciliation how-to covers the finalisation sequence in detail.
Common issues discovered during validation
Be alert for these frequently identified problems:
Delayed rate increases
Award rate increases weren’t applied from the correct date. Annual minimum wage increases, for example, take effect from the first full pay period on or after 1 July. Processing delays create underpayment liability.
Incorrect employee classification
Employees classified under the wrong award classification level. This affects base rates, penalty calculations, and entitlements. Classification reviews should be part of ongoing HR processes.
Leave accrual errors
Leave accruing at incorrect rates, typically when part-time hours change or employment type changes from casual to permanent. System configuration may not automatically adjust accrual rates.
Penalty rate miscalculations
Penalties applied at wrong rates or wrong times. Evening penalty start times, public holiday rates, and Sunday rates are common error areas. Manual systems are particularly prone to these mistakes.
Terminated employees not finalised
Staff who left during the year still showing as active, final pays not fully processed, or unused leave payouts and any redundancy amounts not correctly recorded. Every terminated employee needs a clean, finalised YTD record before you lodge.
Reportable amounts missed
Reportable fringe benefits (RFBA) and reportable employer super contributions not captured against the right employees. These feed STP finalisation and, if missed, force an amendment after year-end.

Frequently asked questions
What payroll data should be validated before EOFY?
Key validation areas include employee classification and pay rates, superannuation calculations and payments, leave balances and accruals, overtime and penalty rate calculations, allowances and deductions, tax withholding amounts, gross and net pay reconciliations, and year-to-date totals against payslips. Thorough validation prevents issues from carrying into the new financial year.
When should EOFY payroll validation begin?
Begin validation in April to allow adequate time for investigation and correction. High-level checks can start earlier. Detailed employee-by-employee validation should be complete by mid-June. Leave buffer time before 30 June for any necessary adjustments. Rushing validation in the final week leads to errors and missed issues.
When is the STP finalisation deadline?
For most employers the Single Touch Payroll finalisation declaration is due to the ATO by 14 July. Validation and finalisation are separate steps: validate your payroll data by mid-June, run a final year-to-date reconciliation after your last pay run, then lodge the finalisation by 14 July. If you find an error after finalising you must lodge an amended finalisation, so it’s worth reconciling the year-end totals carefully first.
How do you validate superannuation calculations for EOFY?
Verify that the correct super guarantee rate was applied throughout the year (12% for 2025-26), that super was calculated on ordinary time earnings correctly, that salary sacrifice arrangements were processed properly, that the maximum super contribution base was applied where relevant, and that all quarterly payments for 2025-26 were lodged and paid on time. Note: from 1 July 2026, Payday Super replaces the quarterly cycle. Reconcile super payable with actual payments made.
How does Payday Super affect EOFY 2026?
The 2025-26 EOFY sits right on the transition. Your April–June 2026 super is still under the quarterly cycle, with the Q4 payment due 28 July 2026. From 1 July 2026 Payday Super begins, meaning contributions must reach the employee’s fund within 7 business days of each pay run, and the Small Business Superannuation Clearing House closes. Validate Q4 is paid on time under the old rules and confirm your fund and clearing-house setup is ready for the new same-cycle obligation.
What leave balance validation is required before EOFY?
Validate that leave accrual rates match employment type and awards, that leave taken has been correctly recorded and deducted, that leave loading was paid correctly where applicable, that long service leave calculations are accurate for eligible employees, and that leave balances reconcile with payroll records. Leave liability affects financial statements and employee entitlements.
How do you handle terminated employees at EOFY?
Confirm every employee who left during the year has a fully processed final pay, that unused annual leave payouts and any redundancy or notice amounts were recorded correctly, and that their year-to-date figures are clean before you finalise. Terminated staff still need to appear correctly in your STP finalisation, so an unfinalised or mis-recorded final pay is a common cause of after-EOFY amendments.
How do you identify underpayment issues before EOFY?
Compare actual pay rates against applicable awards, verify penalty rates were applied correctly for all shifts, check that minimum engagement requirements were met, review overtime calculations against award requirements, and validate that allowances were paid correctly. Use time and attendance data as a source of truth for hours and shift timings.
What reconciliations are essential before EOFY?
Essential reconciliations include payroll register to general ledger, superannuation payable to payments made, PAYG withholding to BAS lodgements, gross wages to the STP finalisation figures, leave liability to leave balances, and timesheet hours to payroll hours. These reconciliations identify discrepancies before they become audit findings. Our guide on reconciling payroll variances covers how to investigate any mismatch.
How should payroll errors found before EOFY be corrected?
Document each error and its cause, calculate the correct amount and difference, process adjustments in the current financial year where possible, communicate with affected employees, update records to prevent recurrence, and retain documentation for audit purposes. Processing corrections before EOFY is easier than making amendments after year-end.
What systems should integrate for effective EOFY validation?
Effective validation requires integration between time and attendance systems, rostering systems, payroll software, HR information systems, and accounting systems. Data should flow cleanly between systems with reconciliation points. Manual data transfer creates validation challenges and error opportunities.
