New Zealand Sole Trader Tax Calculator
Estimate your New Zealand sole-trader tax — IRD income tax (2025-26 brackets), the ACC earners' levy, and your GST registration threshold.
Estimated total tax
NZ$8,918
Effective rate 17.2% on NZ$52,000 net profit
GST: above NZ$60,000 you must register, charge 15% GST and file GST returns. Sole traders report business profit on their IR3 individual tax return and usually pay provisional tax in instalments once residual income tax passes NZ$5,000. The ACC earners' levy shown is a simplified estimate.
Estimates use latest published figures (US 2025 brackets & 15.3% SE tax, UK Self Assessment bands + Class 4 NI, Canada federal + CPP, Germany §32a 2026 income tax + est. social & 19% VAT, GCC VAT rates). Simplified estimate for planning only — not tax advice.
