New Zealand tax & payroll calculator guide

Use the calculators for planning, then confirm current rates, allowances, contribution rules, and effective dates with the official authority. Calculum uses the numbers you enter; it does not reproduce New Zealand tax law.

What materially changes

Rules to separate in a New Zealand estimate

  • PAYE deductions can interact with ACC levies, student loan deductions, and KiwiSaver contributions.
  • Employer contributions and employee deductions should not be treated as the same payroll cost.
  • Consumer prices are commonly GST-inclusive, although the tax treatment of a supply still needs checking.

Prices and purchases

New Zealand: GST

Consumer prices are commonly GST-inclusive; a tax-exclusive price must be made clear.
