Duplicate reversal mess

Hi everyone,

I’m hoping someone with MYOB payroll experience can help me untangle a payroll issue that occurred after I entered an incorrect payment date.

Normal process

Our pay runs operate Monday to Sunday, and we always set the payment date as the Sunday so payroll reports align with our weekly reconciliation.

What went wrong

Last week I accidentally processed a payroll with the wrong payment date 02/03/2026 instead of 01/03/2026.

While trying to correct it, a series of reversals and electronic payment actions were performed. This seems to have created multiple payroll postings and reversals.

What the file now shows

From reviewing reports Payroll Activity, General Ledger Detail and Payroll Category Transactions-

Payroll entries exist on 01/03/2026 corrected run however due to a double reversal for each pay in this run I believe this is where my STP reporting may be inaccurate-possibly requires another dummy pay run? 

Multiple payroll entries exist on 02/03/2026- previous employees and current. Some $0 and some old pays. - These don’t appear to be affecting figures from what I can see. 

Upon processing pay run for 2/03/2026-08/03/2026 I found all of the reversals random employee voids in the electronic clearing account. A series of positive and negative amounts and duplicates. I followed community forum steps to clear them from the account. 

Now those Payroll entries exist again on 08/03/2026 (next correct run), my weekly activity summary shows the correct pay runs if I look week to week but with random cents amounts added and missing one pay entirely. If I look at the month there is only one pay run in there again with the random cents and missing pay item. The entries also exist in my transaction journal correctly for both weeks. I don’t actually use the bank file to pay staff so correct pays were paid both weeks. 

The 02/03/2026 entries appear several times, including transaction ranges like:

7037 to 7053

CD000033 to CD000049

 CD000050 CD000067 

For context I have 17 staff

These appear to contain the same wages, tax and super lines duplicated multiple times.

Current symptoms

Payroll Activity Summary is missing some employees

Some employees show $0 activity

Payroll reports show unexpected cents

STP reports contain multiple reversal entries

Electronic Clearing Account had multiple debit entries from attempted bank file corrections- these are cleared. 

Profit and Loss has a negative wage figure for most recent pay run. 

Advice from MYOB support

They suggested creating a correcting pay run equal to the reversal amounts to offset the duplicate reversals.

However I’m also considering restoring a backup from before the issue occurred and re-entering the affected payroll transactions, which may be simpler.

Quite the mess from a lag in the system at the time of reversal. I’ve looked at so many figures, google searches, community forums and spoken to MYOB and feel like I’ve not really become any clearer on what’s happened. 

Any advice from others who have encountered similar MYOB payroll duplication issues would be greatly appreciated.

Thanks in advance.
