Singapore vs United Kingdom for Australians leaving home
The regimes are genuinely different: Singapore is a territorial tax system while United Kingdom runs worldwide tax, which of your income streams each one actually touches matters more than any headline rate.
Both have a tax treaty with Australia, so either way you get a tie-breaker if the ATO contests your departure, and capped withholding (15%/10% vs 15%/10% on unfranked dividends/interest).
On day-to-day costs there is little between them, roughly 110% and 105% of Sydney's basket (indicative, ex-rent), so the money question is decided by tax and rent, not groceries.

|---|---|---|
| Tax | ||
| Regime | territorial, worldwide income not taxed | worldwide, taxes worldwide income |
| Income tax on salary | Progressive 0, 24%. A S$250k salary pays roughly 18% effective. | 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 capital gains tax for individuals. (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 | Singapore dividends tax-free (one-tier); foreign dividends generally exempt for individuals. | 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 CGT: investment gains untaxed. Trading as a business is taxable income, frequency and intent matter. | 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 | Yes, AU withholding capped at 15% dividends / 10% interest, tie-breaker available | Yes, AU withholding capped at 15% dividends / 10% interest, tie-breaker available |
| Social security | CPF applies only to citizens/PRs, most expats on passes pay no CPF. | 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?”
Singapore
- No general nomad/retirement pathway: without a job, a business or serious capital, there is no way in.
- The world’s most expensive city on several measures, school fees and rent will eat a big share of the tax saving.
- A 4,000-a-year national day-count habit: many Australians in Singapore drift over 90 days back home. The treaty helps, but only if Singapore residency is solid.
- Employment Pass renewals are policy-sensitive; your long-term security is COMPASS points, not a right.
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.
