What are an employer's PAYE and KiwiSaver obligations in New Zealand?
New Zealand employers must deduct PAYE (income tax) from employee wages on each payday, file an employment information return within 2 working days, contribute a minimum 3% to KiwiSaver (rising to 3.5% from 1 April 2026), and deduct employer superannuation contribution tax (ESCT) on that contribution.
Detailed Explanation
## Employer Obligations in New Zealand
### Registering as an Employer
Before paying your first employee, register as an employer with IRD through myIR. You will need your IRD number and basic business information. Registering enables access to payday filing and links your employer PAYE account to your employees' IRD numbers.
### PAYE Deductions
Pay As You Earn (PAYE) tax is deducted from employee wages on every payday based on the employee's tax code (provided on an IR330 form). In addition to income tax, PAYE deductions include the ACC earner's levy (approximately 1.60% of gross earnings up to the annual maximum of NZD 142,283 for 2025-26), student loan repayments (12 cents per dollar above the NZD 22,828 threshold), and child support where applicable.
### Payday Filing
From 1 April 2019, all employers must file employment information returns with IRD on every payday. The return must be filed within 2 working days of each payday for electronic filers. The return includes each employee's name, IRD number, gross earnings, PAYE deducted, student loan deductions, and KiwiSaver contributions for that pay period. Most payroll software files payday returns automatically.
### PAYE Payment Due Dates
Small employers (total PAYE including ESCT under NZD 500,000 per year): pay PAYE by the 20th of the month following the pay period.
Large employers (PAYE + ESCT over NZD 500,000 per year): must pay PAYE twice monthly — by the 5th and 20th of each month.
### KiwiSaver Obligations
Employee contributions
deduct the employee's chosen contribution rate (3%, 4%, 6%, 8%, or 10% of gross earnings) from their pay and pass through to IRD along with PAYE.
Employer contributions
contribute a minimum 3% of the employee's gross earnings as a compulsory employer contribution. From 1 April 2026, the compulsory minimum rises to 3.5%, and to 4% from 1 April 2028.
ESCT (Employer Superannuation Contribution Tax)
the employer's KiwiSaver contribution is subject to ESCT, withheld before it goes to the KiwiSaver provider. ESCT rates: up to NZD 16,800 income = 10.5%; NZD 16,801-57,600 = 17.5%; NZD 57,601-84,000 = 30%; over NZD 84,000 = 33%; over NZD 216,000 = 39%.
### Auto-Enrolment and Opt-Out
New employees aged 18-65 are automatically enrolled in KiwiSaver. They can opt out during days 14 to 56 of employment. If they opt out, stop deductions and refund any already-deducted contributions through IRD. Employees who have previously opted out can be automatically re-enrolled every three years.
### Fringe Benefit Tax (FBT)
Fringe benefits provided to employees (company cars, discounted goods, gym memberships) may be subject to FBT — a tax paid by the employer, not the employee. FBT returns are filed and paid quarterly with an annual reconciliation.

Real-World Examples
First employee — payroll setup
A consultancy hires their first employee at NZD 65,000/year (weekly pay NZD 1,250 gross). PAYE on tax code M: approximately NZD 238/week. KiwiSaver employee deduction (3%): NZD 37.50. Employer KiwiSaver (3%): NZD 37.50, less ESCT at 30% = NZD 11.25. Net employer KiwiSaver to fund: NZD 26.25. PAYE return filed within 2 working days of payday.
Managing KiwiSaver when an employee opts out
A new employee joins and is auto-enrolled. After 3 weeks, they submit an opt-out request. The employer stops deductions, files a KiwiSaver opt-out through myIR, and IRD refunds any employee contributions deducted to date back to the employee. The employer contribution already made is not refunded.
Fringe benefit — company vehicle
A company provides a manager with a vehicle worth NZD 45,000. FBT is calculated quarterly based on 5% of the vehicle's cost per quarter = NZD 562.50 per quarter in FBT liability (before grossing up). The employer pays this additional tax — the employee has no direct FBT liability.
Common Mistakes to Avoid
- Filing payday returns monthly instead of within 2 working days — all electronic filers must file with each payday since 1 April 2019, not monthly
- Calculating ESCT on the wrong amount — ESCT is on the employer's KiwiSaver contribution, not the employee's gross salary
- Not updating employee tax codes when IRD issues a new code — using the wrong code means the employee is over or underpaying PAYE
- Not updating payroll systems ahead of the 1 April 2026 KiwiSaver rate increase to 3.5%, resulting in underpayment of employer contributions
Frequently Asked Questions
Do I need to pay KiwiSaver contributions for casual employees?
Yes, if the casual employee meets the eligibility criteria (NZ citizen or permanent resident aged 18-65 working in NZ). Very short-term contractors (under 28 days) may be treated as contractors rather than employees, in which case PAYE and KiwiSaver do not apply.
What is the difference between an employee and an independent contractor for PAYE purposes?
An employee is under the direct control of the business, works regular hours, and cannot subcontract. A contractor works independently, provides their own equipment, invoices for services, and bears business risk. IRD has a checklist for determining employment status — misclassifying an employee as a contractor is a high-audit-risk practice with penalties.
What are the minimum wage requirements in New Zealand?
The minimum wage for employees aged 16+ is NZD 23.15 per hour as at 1 April 2025. The starting-out and training minimum wage is NZD 18.52 per hour (80% of the adult minimum), available for eligible 16-19-year-olds in their first 6 months of employment or in recognised training programmes. Minimum wage is reviewed annually on 1 April.
How do I handle final pay when an employee leaves?
Final pay must include all unused annual leave at the employee's current rate, any public holidays owed, and other entitlements. PAYE is deducted from the full final pay amount. File the final employment information return with IRD within 2 working days of the final payday, indicating it is a termination pay.
Are KiwiSaver employer contributions deductible for the employer?
Yes. The full employer contribution (including ESCT) is a deductible business expense, reducing the net after-tax cost. The effective after-tax cost of the 3% (or 3.5% from April 2026) contribution is lower than the face rate.
Practical Tips
- Use payroll software from day one — manual payroll calculations are error-prone and modern tools (Xero, MYOB) file payday returns automatically, removing the 2-working-day manual filing obligation.
- Confirm every new employee's tax code and student loan status on their first day using the IR330 form. Using the wrong tax code from the start creates reconciliation issues at year-end.
- Budget for the total employment cost including KiwiSaver (3.5% from April 2026) and employer ACC levies — these add approximately 4-5% on top of gross wages.
- Check IRD's annual updates in March/April each year — minimum wage, ESCT thresholds, and KiwiSaver contribution rates change, and your payroll software should update automatically but it is worth verifying.
