New Zealand tax guide 2026
New Zealand runs one of the developed world's cleanest systems: five income tax rates topping out at 39%, no general capital gains tax, no social security contributions, no inheritance tax and no gift duty. The traps are targeted — residential property flipped within 2 years is taxed, and crypto profits are usually ordinary income because the tax office assumes you bought to sell.
- Rate range
- 10.5% – 39%; no general capital gains tax
- Key allowance
- No personal allowance — tax starts from the first dollar at 10.5%
- Tax year
- 1 April – 31 March
- Filing deadline
- 7 July; most employees are auto-assessed
Taxes covered
- Income tax39%
Five rates from 10.5% to 39% above NZD 180,000 — with no social security on top, just a ~1.4% accident levy.
- Dividend taxup to 39%
Dividends are ordinary income with imputation credits for the company's 28% tax — top-rate holders pay roughly the 11-point gap.
- Capital gains tax0%
No general capital gains tax — the exceptions are land bought for resale and residential property sold within the 2-year bright-line window.
- Crypto tax10.5% – 39%
No capital gains tax doesn't save crypto: the tax office presumes coins are bought to sell, making most disposal profits ordinary income at marginal rates.
- Social security0% + ~1.4% levy
No social security contributions exist — just the accident-compensation Earners' levy (~1.4%, capped) and voluntary KiwiSaver saving.
- Inheritance tax0%
Estate duty and gift duty are both abolished — nothing is charged on death or lifetime giving, at any level.
- Withholding tax15% / 30%
Non-residents: 30% on dividends (15% or less by treaty), 15% on interest and royalties — with a 0% approved-issuer route for interest.
Special regimes
- No capital gains tax
Shares and long-held assets sell tax-free — only land bought to flip and residential property sold within 2 years are taxed.
- Transitional resident exemption
New migrants and returning Kiwis (10+ years away) pay no tax on most foreign income for 48 months.
- No social security contributions
Only a small accident-compensation levy (~1.4%) comes out of pay; KiwiSaver retirement saving is voluntary.
- No inheritance or gift taxes
Estate duty and gift duty are both abolished — no tax charge arises on death or gifts, though inherited assets can carry later income or property-rule consequences.
