New Zealand vs Portugal for Australians leaving home
New Zealand and Portugal run the same headline regime, worldwide tax, so the decision turns on the details underneath: what each one does to capital gains, dividends and the Australian income you keep.
The treaty position splits them: New Zealand has a full Australian tax treaty (tie-breaker plus withholding capped at 15% on unfranked dividends), while Portugal has none, no safety net if both countries claim you.
Portugal is the cheaper place to live day to day, roughly 65% of Sydney's basket against New Zealand's 90% (indicative, ex-rent), which can outweigh a thinner tax saving over a full household budget.

| 2 destinations | New ZealandNew Zealand | PortugalPortugal |
|---|---|---|
| Tax | ||
| Regime | worldwide, taxes worldwide income | worldwide, taxes worldwide income |
| Income tax on salary | Progressive 10.5, 39%. No tax-free threshold at all (the first dollar is taxed) but effective rates at middle incomes land close to Australia's. | Progressive 13, 48% plus solidarity surcharge above €80k. A €100k salary pays roughly 37% effective, Portugal is not a low-tax country for salaries. |
| Capital gains | No general CGT: long-term share gains untaxed. Exceptions: traders, property inside the bright-line window, and the FIF deemed-return regime on non-ASX foreign shares over NZ$50k. (0% typical) | 28% flat on share gains (option to aggregate at progressive rates). Short-term gains on assets held <365 days must be aggregated at progressive rates for high earners. (28% typical) |
| Dividends | Dividends taxed at marginal rates. NZ imputation works like franking; Australian franking credits are NOT usable in NZ, a long-standing trans-Tasman sore point. | 28% flat on dividends and interest, wherever sourced, with no AU treaty relief. |
| Interest | Taxed locally around 33% | Taxed locally around 28% |
| Crypto | No CGT does not mean crypto-free: IRD treats most crypto as bought with intent to sell, making gains taxable income at marginal rates. The onus of proving otherwise is on you. | Crypto held under 365 days is taxed at 28% on disposal; gains on crypto held longer than 365 days are exempt for individuals. Crypto-to-crypto swaps are generally not taxing events. Professional trading is business income at progressive rates. |
| Australia tax treaty | Yes, AU withholding capped at 15% dividends / 10% interest, tie-breaker available | No, full 30% / 10% withholding, no tie-breaker |
| Social security | No social security tax; ACC earner levy (~1.6%) applies to employment income. KiwiSaver is opt-in for migrants. | Employees pay 11% social security; the self-employed pay ~21.4% on a discounted base. Not included in the calculation above, budget for it. |

Honest downsides, side by side
Every destination hub on this site carries its downsides in the open. Here are both lists together, because the right question is rarely “which is better?” and usually “which set of problems would you rather live with?”
New Zealand
- The tax saving is thinner than it looks: no CGT is real, but income rates are Australia-like, there is no tax-free threshold, and salaries are 15, 25% lower for the same role.
- The ATO treats a hop to Auckland with scepticism, same time zone, 3-hour flights, easy return; your "permanent departure" evidence needs to be stronger, not weaker, than for Dubai.
- Auckland housing rivals Sydney for unaffordability, and the cost-of-living basket is not meaningfully cheaper.
- Earthquake and weather-event risk is priced into insurance, and the economy is small, career ceilings arrive quickly outside a few sectors.
Portugal
- No Australia tax treaty: a contested residency year can leave the same income fully taxed in both countries with only messy unilateral credits between you and double tax.
- NHR is gone for new arrivals, the 20% IFICI successor is narrow, and most Australians will face full progressive rates up to 48% plus 28% on investments.
- Salaries and bureaucracy are Southern European: local pay is low, AIMA appointment backlogs are real, and everything official takes months.
- It is the single worst time zone on this list for keeping Australian clients, 9, 10 hours behind AEST means your overlap is their evening.
- Winter housing is genuinely cold and damp; central heating is the exception, not the rule.
