Refunds can only be done in Ace Payroll if the contribution has not already been paid to Inland Revenue.
This procedure reverses the KiwiSaver contributions from the PAYE Employer Deductions IR345, and the Employer Monthly Schedule IR348, so they are not paid to the IRD.
Any contributions that are sent to Inland revenue before the employee opts out will be automatically repaid by Inland Revenue.
This process is only possible for the first 2-3 weeks of employment for each employee. After that time the Reverse button will not be shown.
