KiwiSaver
KiwiSaver is New Zealand’s voluntary, work-based retirement savings scheme, with contributions commonly deducted and paid through payroll.
KiwiSaver helps people save for retirement through a managed investment fund. Many eligible employees are automatically enrolled when they start a new job, although joining, opting out, pausing contributions and making withdrawals are governed by separate rules.
For an employer, KiwiSaver is mainly a payroll and record-keeping responsibility. Employee deductions, employer contributions and the tax on employer contributions are different amounts and should not be combined. Inland Revenue is the central administrator and passes contributions on to scheme providers. Its KiwiSaver guidance is the official starting point for current rules.
Where KiwiSaver Appears
A small business may see KiwiSaver in:
- employee onboarding forms and payroll settings
- each affected pay run and payslip
- payday filing and payroll reports
- payroll liability accounts awaiting payment
- bank transactions sent to Inland Revenue
- accountant or payroll-adviser checks of deductions, contributions and ESCT
The three payroll amounts serve different purposes:
| Amount | What It Represents | Typical Payroll Treatment |
|---|---|---|
| Employee Contribution | Money deducted from the employee’s pay | Recorded as a deduction and liability until remitted |
| Employer Contribution | Money contributed by the employer | Recorded as an employer cost and liability |
| ESCT | Employer superannuation contribution tax | Deducted from the employer contribution and recorded separately |
How KiwiSaver Works In Practice
An employer first checks whether a new employee is already a member or should be automatically enrolled. Payroll then applies the employee’s selected contribution rate, records any required employer contribution and calculates employer superannuation contribution tax (ESCT).
From the first payday on or after 1 April 2026, the standard employee contribution rate and the minimum compulsory employer contribution became 3.5% for employees to whom those settings apply. Other contribution rates and an approved temporary rate reduction may apply, so payroll should follow the employee’s valid instructions and current Inland Revenue settings. Inland Revenue’s employer-contribution guidance explains the current employer rules and exceptions.
After the pay run, employee deductions, employer contributions and ESCT are sent through the payroll process. Until they are paid, the amounts are normally liabilities rather than spare business cash.
Simple Example
Suppose a pay run records $70 deducted from an employee’s pay and a $70 gross employer contribution. The two $70 amounts are not the same transaction: one comes from the employee’s gross pay and the other is an employer cost.
If $14 of ESCT is withheld from the employer contribution in this simplified example, the employee’s scheme receives a net $56 employer contribution. Payroll and the general ledger should still show the $70 employer cost, the $14 tax and the payment amounts separately. The real calculation depends on the employee’s circumstances and current rules.
Why KiwiSaver Matters
Incorrect setup can affect an employee’s take-home pay, retirement savings, employer costs and payroll liabilities. It can also create differences between the pay run, payday filing, the amount sent to Inland Revenue and the bank transaction.
Clear records make those differences easier to find. Reconcile the payroll report to the liability accounts and then reconcile the payment to the bank, just as you would for PAYE or other payroll deductions.
Regional Variations
KiwiSaver is specific to New Zealand. Australia’s Superannuation Guarantee also supports retirement saving, but it has different agencies, contribution rules and earnings definitions. Ireland’s MyFutureFund, Canada’s public pension contributions and Singapore’s CPF are separate systems as well, not alternative names for KiwiSaver.
How Gimbla Can Help
Gimbla can keep the accounting entries produced by a payroll process alongside expenses, liabilities and bank transactions. Separating employee deductions, employer contributions and ESCT makes it easier to match the payroll journal to the later bank payment without treating the remittance as a second expense.
