Open calculatorGood questions. Clear answers.
Is this an official Inland Revenue calculator?
No. Free Tax Calculator NZ is an independent estimate tool. Our rates are linked to official sources, but we are not affiliated with or endorsed by Inland Revenue.
Why could my payslip show a different amount?
We annualise steady earnings. Payroll rounding, secondary jobs, tailored codes, partial years, benefits and irregular lump sums can produce different results. Check your employer’s calculation or Inland Revenue for payroll decisions.
Do I need an account?
No. All calculators work without an account. An optional account lets you save and reopen calculations.
