When setting up contributions/deductions for a KiwiSaver complying superannuation fund, make sure you select the correct Contribution Category and Type when creating the Employer Contribution and Deduction codes:
Choose Setups, Payroll, Employer Contributions/Deductions, Maintain.
For Employer Contributions, set the Contribution Category to C - Complying Superannuation Fund (NZ).
For Deductions, set the Type to Y - Complying Superannuation Fund (NZ).
📌Note: You may need to review the ESCT rate in the employee's Masterfile (on the Tax Details tab). Check the IRD website to help determine whether the contribution is to be taxed and at what rate.
