PAYE / KiwiSaver deductions calculator

About this calculator

Employers and employees can work out how much PAYE should be withheld from wages paid weekly, fortnightly, four-weekly or monthly.

Use of this tool does not result in data being submitted to us.

When to use this calculator

Based on the details you give us, you can:

  • calculate how much PAYE / KiwiSaver / student loan should be withheld from weekly, fortnightly, four-weekly or monthly wages
  • work out the PAYE on cash payments to get the gross figure for the net cash amount
  • calculate any required KiwiSaver employee deductions, net employer contributions and ESCT payable.

The calculator can also calculate PAYE on holiday pay when it is paid:

  • as part of an employee’s regular pay at the rate of 8% of the employee’s gross earnings; or
  • instead of the employee’s regular pay when the employee takes annual leave, or
  • a lump sum in advance and is taxed using the alternative approach, or
  • to a non-resident seasonal worker who is using the "NSW" tax code.

The holiday pay amount is included with the employee’s regular pay and a separate PAYE calculation is not needed.

However, if the holiday pay that is paid as a lump sum and is treated as an extra pay, you will need to do a separate PAYE calculation.

What you will need

You will need to know details of the salary / wage for the pay period and the appropriate tax code.

If you're an employer you will need to know if your employee:

  • is a KiwiSaver or complying fund member and the employee's contribution rate
  • is a member of any other superannuation scheme, and
  • your employee's ESCT rate.
After you finish

If you're calculating for several people, the name and the reference number will identify the different calculations.
