Currently MYOB Acumatica Payroll has no direct functionality for closedowns.
Until MYOB improves this workflow (which is in the pipeline), you will need to undergo a manual process to make payments for annual closedowns. This article is about manually processing a mandatory closedown pay run in MYOB Acumatica Payroll.
If you are obliged to pay your employee an “8% payment” (see the Employment New Zealand Annual Closedowns page for more information on whether this applies to you), this can be done in MYOB Acumatica in a similar way to processing payments of accrued leave on termination. The “termination wizard” in MYOB Acumatica Payroll provides you with the easiest way to choose a date and get the relevant values in return.
This PDF will guide you through using the termination wizard to get the value of the payment.
