If you make a mistake on your Employer Monthly Schedule, the solution depends on where you are in the process.
Before you file your Employer Monthly Schedule IR348 with Inland Revenue
Ace Payroll allows you to create a digital EMS as many times as you wish. If you make a mistake, you can just go back and create a new file. The new file overwrites the old file.
After you file your Employer Monthly Schedule IR348 with Inland Revenue
If you have already filed you EMS with Inland Revenue and have made a mistake, you cannot re-file it because myIR will reject it. The system also rejects any EMS containing a negative amount. This means that creating a negative entry on the next month's EMS will not work.
To amend an EMS you have already filed, fill out an Employer monthly schedule amendments (IR344) form, and file it online through myIR. You can amend up to three employees' details per form. Use separate forms if there are more than three. If you only have a small number of adjustments, you can call Inland Revenue and update them over the phone.
