NZ vs UK Tax — Side-by-Side Comparison for 2025-26 / 2026-27
New Zealand and the UK both run progressive PAYE income tax with a national health/social levy and tax-deferred retirement, but the structural details (no tax-free threshold in NZ, no NI in NZ, KiwiSaver vs auto-enrolment, GST 15% vs VAT 20%) materially change your take-home if you cross corridors. This page compares income tax, social levies, retirement schemes, and consumption tax using IRD 2025-26 figures and HMRC 2026-27 figures (rest of UK).
Take-home pay on the same nominal salary
Same numeric amount taxed as both an NZD salary (IRD) and a GBP salary (HMRC + Class 1 NI). Currencies aren't directly comparable — this is a structural tax comparison, not a cost-of-living comparison.

Gap shows NZ take-home minus UK take-home on the same nominal gross salary. Excludes KiwiSaver / pension contributions to isolate the tax-only effect. UK figures use rest-of-UK 2026-27 (Scotland uses different rates).

Retirement: KiwiSaver vs UK pensions / ISA
UK auto-enrolment is mandatory; KiwiSaver is opt-in but has near-universal participation. KiwiSaver employer minimum is now 3.5% — up from 3% before 1 April 2026, rising again to 4% on 1 April 2028; employee chooses 3%, 3.5%, 4%, 6%, 8%, 10% with 3.5% the current default. UK auto-enrolment is 8% combined (3% employer + 5% employee from gross salary). Net contribution rate at the same nominal salary is roughly 7.0% in NZ (3.5%+3.5% default) vs 8% in UK.
UK ISA has no clean NZ equivalent. £20,000/yr (2026-27), tax-free growth, tax-free withdrawal, no income limits. NZ's PIE structure (Portfolio Investment Entity) caps the tax rate on portfolio income at 28% PIR — a meaningful relief for top-bracket savers but not as generous as the UK ISA.
Cross-border treaty. The NZ-UK treaty recognises pensions for treaty purposes. Direct transfers between KiwiSaver and UK QROPS schemes are not generally permitted (NZ funds aren't QROPS-recognised); both stay in their home country. Withdrawals are taxed in the country of residence (with foreign tax credit). ISAs lose tax efficiency on NZ residency; KiwiSaver loses preferential treatment on UK residency.
If you're moving NZ → UK
- Tax residency: NZ residency typically ends 325 days after leaving (or earlier if you break your permanent place of abode). UK residency triggers under the SRT — 183+ days, or 91+ days with UK ties.
- KiwiSaver: Stays in NZ; locks until age 65 (with limited first-home / hardship exceptions). Treaty-recognized as a foreign pension; no annual UK taxation on growth.
- Student loan: NZ student loan deductions continue under the overseas-based borrower schedule — flat annual amount based on loan balance, regardless of UK income.
- Lower take-home in UK: Expect take-home to drop on the same nominal salary, especially in the £100k–£125,140 PA-taper range (60% effective marginal). NZ's lack of NI / tax-free threshold balance shifts the comparison at lower incomes.
- NHS access: Available immediately to UK residents — no premium equivalent.
- Property: SDLT (or LBTT/LTT) applies on UK home purchase. UK FHB relief up to £425k, partial up to £625k.
If you're moving UK → NZ
- Tax residency: NZ residency triggers after 183 days in any 12-month period, or earlier if you have a 'permanent place of abode' here. UK residency ends per the SRT — typically when you leave for full-time work overseas.
- UK pension: Stays in UK; treaty-recognized as NZ pension (no annual NZ taxation on growth). Withdrawals taxed at marginal NZ rate; UK 25% lump-sum is NOT tax-free under NZ rules — taxed as ordinary income.
- ISA caution: Lose tax efficiency on NZ residency — IRD taxes growth and dividends as a regular taxable account. Consider closing or moving to cash before NZ move.
- KiwiSaver opening: Once tax-resident, you can join KiwiSaver. Government Contribution: $260.72/yr maximum (2025-26, post-Budget halving) for personal contribution of $1,042.86+.
- No NI / no IHT: NZ has no National Insurance equivalent and no inheritance tax — both meaningful structural differences worth pricing into the move.
- Higher take-home at most incomes: NZ typically beats UK on the same nominal salary, especially at higher bands where UK PA taper bites.
Frequently asked questions
Is New Zealand or the UK a lower-tax country?
For most working incomes, New Zealand takes home more on the same nominal salary than the UK because NZ has no NI equivalent and lower bracket rates above the basic band. At $80,000 gross, NZ take-home is $62,387 (effective 22.0%) versus UK $56,957 (effective 28.8%). The gap widens at higher incomes due to the UK 60% effective marginal trap (£100k–£125,140 PA taper) which has no NZ equivalent.
How does KiwiSaver compare to UK auto-enrolment / SIPP?
KiwiSaver is opt-in (auto-enrolled from 18); employer minimum is now 3.5% (up from 3% before 1 April 2026, rising again to 4% from 1 April 2028). Employee contribution: 3%, 3.5%, 4%, 6%, 8%, 10% — 3.5% is the current default. UK auto-enrolment is 8% combined (3% employer + 5% employee from gross), automatic for £10k+ earners. Net mandatory contribution to retirement at the same nominal salary is roughly 7.0% NZ (3.5%+3.5% default) vs 8% UK. UK pension access age 55 (rising to 57 from 2028); KiwiSaver access at NZ Super age 65.
If I move from NZ to the UK, what happens to my tax residency?
NZ tax residency typically ends 325 days after leaving (or earlier if you break your permanent place of abode). UK residency triggers under the Statutory Residence Test (SRT) — most commonly 183+ days in a UK tax year (6 April – 5 April), or 91+ days with a UK tie. The NZ-UK tax treaty prevents most double taxation; foreign tax credits available on cross-border income.
Can I transfer my KiwiSaver to a UK pension?
Generally no — KiwiSaver funds are not QROPS-recognized so transfers from UK pensions trigger a 25% Overseas Transfer Charge. KiwiSaver itself stays in NZ and locks until age 65 (with first-home and hardship exceptions). UK pensions cannot be transferred to KiwiSaver. Most UK↔NZ movers leave their pensions in place; withdrawals are taxed in the country of residence with foreign tax credit.
Is GST/VAT different between NZ and the UK?
Yes — New Zealand's GST is 15% (broad base, almost no exemptions). The UK VAT is 20% standard, with 5% on domestic energy and 0% on most food, kids' clothes, and books. Effective consumption-tax burden depends on spending mix: UK is generally higher on discretionary goods but lower on essentials (food). NZ's broader base means it captures more of total spending.
