For employers wanting to provide benefits to employees in the form of an
Employee Share Scheme (ESS).
Deducting tax is optional because it won't suit all schemes. If you do deduct PAYE, then student loan and child support amounts must also be deducted (if applicable). Employee share scheme benefits are not liable for the ACC earners' levy or KiwiSaver deductions. Benefits are taxed as "extra pay or lump sum". These payments are to be shown as a separate line item on the Employer Monthly Schedule report (EMS) sent to IR.
In iPayroll set up your 2 Pay Elements (Payment and Deduction) depending on if you have chosen taxable or non taxable, then add them both to your employee's timesheet entry in an open pay.
