Dubai vs United Kingdom for Australians leaving home
The regimes are genuinely different: Dubai is a zero personal tax system while United Kingdom runs worldwide tax, which of your income streams each one actually touches matters more than any headline rate.
The treaty position splits them: United Kingdom has a full Australian tax treaty (tie-breaker plus withholding capped at 15% on unfranked dividends), while Dubai has none, no safety net if both countries claim you.
Dubai is the cheaper place to live day to day, roughly 95% of Sydney's basket against United Kingdom's 105% (indicative, ex-rent), which can outweigh a thinner tax saving over a full household budget.

| Regime | zero, worldwide income not taxed | worldwide, taxes worldwide income |
| Income tax on salary | No personal income tax on employment income. 0% at every level. | Progressive 20/40/45% plus employee NI (8% then 2%). The £100k, £125k allowance taper creates a 60% effective band. A £120k salary pays roughly 36% effective with NI. |
| Capital gains | No personal capital gains tax. (0% typical) | 18% basic / 24% higher rate on shares and crypto, £3,000 annual exemption. FIG-regime arrivals: foreign gains tax-free for 4 years. (24% typical) |
| Dividends | No personal tax on dividends or interest received. | 8.75/33.75/39.35% above a £500 allowance. Australian franking credits are not recognised, but for FIG-regime arrivals, Australian dividends are simply outside UK tax for 4 years. |
| Interest | Generally untaxed locally | Taxed locally around 40% |
| Crypto | No personal tax on crypto disposals. Frequent trading through a business structure can attract corporate tax. | Crypto disposals are CGT events at 18/24% with a small annual exempt amount (£3,000). Swaps and spending count. HMRC receives exchange data; FIG-regime arrivals can realise foreign crypto gains UK-tax-free in years 1, 4. |
| Australia tax treaty | No, full 30% / 10% withholding, no tie-breaker | Yes, AU withholding capped at 15% dividends / 10% interest, tie-breaker available |
| Social security | No social security for expats; end-of-service gratuity applies to employees instead. | Employee National Insurance (8% to ~£50k, 2% above) is excluded from the calculation above, add it for employment income. |

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?”
Dubai
- No Australia tax treaty: if your residency status is contested, there is no tie-breaker. You can be fully taxed in both places on the same income.
- Summer is genuinely brutal; many expat families leave for two months a year (watch your Australian day count when they head "home").
- Renting and schooling costs rival Sydney; the tax saving is real but the cost base is not cheap.
- Everything rests on your visa: lose the job, and the clock starts on leaving.
United Kingdom
- This is a higher-tax country than Australia for most: 40% starts around A$100k equivalent, NI stacks on top, and the £100k, £125k taper creates a 60% zone with childcare cliff-edges.
- London costs Sydney money without Sydney weather, and the FIG honeymoon is exactly 4 years, after which worldwide taxation lands in full.
- Visa costs are the world's highest: fees plus the health surcharge can run £15, 20k for a family before anyone earns a pound.
- Winter darkness (8-hour days, weeks of grey) is the quiet reason many Australians go home.
