Understanding how to figure payroll taxes in New Zealand means managing several payroll obligations, not one single tax. Employers must deduct PAYE, ACC earners’ levy, KiwiSaver contributions, student loan repayments, and child support where applicable, while also handling employer-side costs such as KiwiSaver contributions, ESCT, ACC Work levy, and Fringe Benefit Tax.
Each obligation has its own rule, rate, and reporting treatment. That makes accurate employee setup essential. Employers need the right tax code, IRD number, KiwiSaver status, pay details, and deduction instructions before running payroll. For overseas companies hiring in New Zealand, even a small setup error can affect employee net pay, employer costs, and Inland Revenue reporting.
Here is a step-by-step way to calculate payroll taxes in New Zealand
Step 1: Collect Employee Payroll Details
Before running payroll, confirm the employee’s setup details:
- IRD number
- Completed tax code declaration
- KiwiSaver enrolment status
- KiwiSaver contribution rate
- Student loan status
- Child support notice, if applicable
- Pay frequency and employment type
If an employee does not submit a completed IR330 tax code declaration, the employer must use the ND tax code and follow Inland Revenue’s salary deduction rules to deduct PAYE at the non-notified rate.
These details help employers understand how to figure payroll taxes correctly before running payroll.
Step 2: Calculate Gross Earnings
Start with the employee’s gross earnings for the pay period.
This may include:
- Salary or hourly wages
- Overtime
- Bonuses and commissions
- Holiday pay
- Back pay
- Taxable allowances
- Other taxable cash payments
Not every payroll item is treated the same way. PAYE applies to salary and wages, KiwiSaver applies to eligible gross salary or wages, ACC earners’ levy is collected through PAYE, and FBT applies to certain non-cash benefits rather than ordinary wages.
Step 3: Deduct PAYE and ACC Earners’ Levy
PAYE is the main payroll deduction in New Zealand. Employers deduct it from employee wages and pay it to Inland Revenue.
PAYE includes:
- Employee income tax
- ACC earners’ levy
For the 2026-27 tax year, the ACC earners’ levy is 1.75% and applies up to maximum liable earnings of $156,641.
Employers should check:
- The employee’s tax code
- Whether the payment is regular pay or extra pay
- Whether student loan deductions apply
- Whether child support deductions have been instructed
- Whether the payroll software is applying PAYE and ACC correctly
PAYE is one of the first items employers review when learning how to figure payroll taxes for New Zealand employees.
Step 4: Deduct KiwiSaver Contributions
KiwiSaver is New Zealand’s workplace retirement savings scheme. For enrolled employees, the employer deducts the employee’s contribution from wages and also makes an employer contribution.
From 1 April 2026, the minimum employee and employer KiwiSaver contribution rate increased from 3% to 3.5%.
Employers should confirm whether the employee:
- Is enrolled in KiwiSaver
- Has selected a higher contribution rate
- Has opted out
- Is on a savings suspension
- Is eligible for employer contributions
Step 5: Calculate ESCT
Employer KiwiSaver contributions are subject to Employer Superannuation Contribution Tax.
Key points:
- ESCT is deducted from the employer contribution, not from ordinary employee wages.
- The ESCT rate depends on the employee’s income band.
- An incorrect ESCT setup can affect KiwiSaver reporting and payroll reconciliation.
Step 6: Deduct Student Loan or Child Support Amounts
Additional deductions may apply depending on the employee’s situation.
Student loan deductions apply when:
- The employee uses a tax code with “SL”
- Inland Revenue instructs the employer to deduct repayments
- The employee earns above the relevant repayment threshold
Child support deductions apply when:
- Inland Revenue sends a deduction notice
- The deduction is processed through payroll
- Protected net earnings rules are followed
Employers should not manually apply these deductions unless the employee’s tax code or Inland Revenue instruction supports it.
Step 7: Account for ACC Work Levy
The ACC earners’ levy is collected through PAYE, but the ACC Work levy is separate.
The ACC Work levy is:
- An employer cost
- Based on business activity classification
- Calculated using liable earnings and the applicable levy rate
- Usually invoiced by ACC rather than deducted each payday
Employers also need to budget for the ACC Work levy, which is calculated using the business’s liable income and the applicable levy rate for its activity classification.
Step 8: Check Fringe Benefit Tax
Fringe Benefit Tax may apply when employers provide non-cash benefits.
Common examples include:
- Private use of company vehicles
- Subsidized goods or services
- Low-interest loans
- Certain insurance benefits
- Gift cards or vouchers
FBT is an employer tax. It is separate from PAYE and is not deducted from the normal salary.
Step 9: File and Pay Payroll Deductions
New Zealand uses payday filing. Employers must report employment information to Inland Revenue after every payday.
Key filing points:
- Employment information is filed after each pay run.
- Electronic filing is generally due within two working days of payday.
- Paper filing is generally due within 10 working days.
- PAYE and related deductions must be paid by the employer’s applicable due date.
- Filing and payment deadlines are also important when deciding how to figure payroll taxes accurately for each pay period.
- Larger employers may have more frequent payment obligations.
Employers must also complete payday filing after each pay run, with employment information submitted to Inland Revenue within the required filing window.

Why Payroll Gets Complicated for Remote Hiring
For overseas companies hiring in New Zealand, payroll is not just about paying salary on time.
Employers must also manage:
- Inland Revenue registration and reporting
- Correct PAYE deductions
- KiwiSaver enrolment and contributions
- ESCT rate selection
- ACC levy exposure
- Student loan and child support deductions
- Payday filing deadlines
- Local employment compliance
This is where payroll services in New Zealand help companies manage local payroll processing, deductions, filings, and compliance without building everything internally.
For companies hiring without a local entity, Employer of Record services allow compliant hiring while the business manages the employee’s day-to-day work.
For overseas companies, the challenge is not just calculating deductions. It is also understanding how local hiring rules, payroll setup, and compliance requirements work together, especially when managing New Zealand employees without an in-country team.
Conclusion
Knowing how to figure payroll taxes in New Zealand starts with accurate gross pay, the correct tax code, and up-to-date employee declarations. Employers then need to calculate PAYE, ACC earners’ levy, KiwiSaver deductions, ESCT, student loan repayments, child support deductions, and any employer-side obligations such as ACC Work levy or FBT.
In 2026, the biggest payroll risks come from small setup errors: wrong tax codes, missed KiwiSaver changes, incorrect ESCT rates, late payday filing, or poor payroll system configuration.

Frequently Asked Questions on How to Figure Payroll Taxes in New Zealand
1. How do you figure payroll taxes in New Zealand?
Start with gross pay, then use the employee’s tax code to calculate PAYE. Apply KiwiSaver deductions, student loan repayments, child support if instructed, and other lawful deductions. Then calculate employer KiwiSaver contributions and ESCT separately. Finally, file payday information and pay deductions to IRD.
2. What is PAYE in New Zealand payroll?
PAYE stands for Pay As You Earn. It is the system used to deduct income tax and ACC earner’s levy from employee salary or wages before net pay is paid. Employers calculate PAYE using the employee’s tax code, pay period, and taxable earnings.
3. What is the KiwiSaver employer contribution rate in 2026?
From 1 April 2026, the default employer KiwiSaver contribution rate increased to 3.5% of an eligible employee’s gross salary or wages. A temporary rate reduction may apply in specific cases. Employers should check IRD guidance before processing affected pay runs.
4. When must employers file payroll information with IRD?
Employers filing electronically must submit employment information within 2 working days of payday. Filing can be completed through myIR, payroll file upload, or compatible payroll software. Filing employment information does not replace the separate obligation to pay deductions to IRD.
5. When are PAYE deductions paid to IRD?
IRD says employers pay deductions once or twice a month, depending on gross annual PAYE and ESCT. Small to medium employers generally pay monthly. Large employers generally pay twice monthly. Employers should confirm their payment schedule using IRD’s current payment guidance.
