FAQs
Which tax year do the New Zealand calculators use?
The 2026–27 tax year, 1 April 2026 to 31 March 2027. Rates come from Inland Revenue's IR340 and IR341 tables and its payroll specification for that year.
Does PAYE include the ACC earners' levy?
Yes. In New Zealand the ACC earners' levy is collected with PAYE, so the PAYE figure your employer deducts already includes it. The calculators show the two parts separately.
Is what I type stored?
