Mexico vs Singapore for Australians leaving home
The regimes are genuinely different: Mexico is a worldwide tax system while Singapore runs territorial 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).
Mexico is the cheaper place to live day to day, roughly 55% of Sydney's basket against Singapore's 110% (indicative, ex-rent), which can outweigh a thinner tax saving over a full household budget.

| Tax | ||
| Regime | worldwide, taxes worldwide income | territorial, worldwide income not taxed |
| Income tax on salary | Progressive 1.92% to 35% (top rate from roughly MXN 4.5m ≈ A$390k). Employees are withheld at source; everyone else deals with SAT directly. | Progressive 0, 24%. A S$250k salary pays roughly 18% effective. |
| Capital gains | Flat 10% on gains from shares sold through a recognised stock exchange. Off-exchange sales (private companies, real estate) are taxed at progressive rates with cost-base indexation for inflation. (10% typical) | No capital gains tax for individuals. (0% typical) |
| Dividends | Mexican dividends: 10% withholding on the net dividend, on top of 30% corporate tax already paid. Foreign dividends and interest are taxed at your progressive marginal rate, Australian franking credits mean nothing to SAT. | Singapore dividends tax-free (one-tier); foreign dividends generally exempt for individuals. |
| Interest | Taxed locally around 35% | Generally untaxed locally |
| Crypto | No dedicated crypto regime: SAT treats disposals as ordinary income or alienation-of-goods gains at progressive rates up to 35%, the 10% exchange rate does not apply to crypto. Guidance is thin; get Mexican advice before realising anything large. | No CGT: investment gains untaxed. Trading as a business is taxable income, frequency and intent matter. |
| 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 | IMSS social security applies to Mexican employment (employer-heavy contributions); self-employed expats generally sit outside it and buy private cover instead. | CPF applies only to citizens/PRs, most expats on passes pay no CPF. |

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?”
Mexico
- Security is genuinely region-dependent: Mexico City neighbourhoods, Mérida and Querétaro feel safer than their reputation; other states are on the DFAT do-not-travel list. Where you live matters more than the country average.
- Bureaucracy runs in Spanish, SAT registration, CFE electricity accounts, banking, INM renewals. Without workable Spanish or a good gestor/accountant, routine admin becomes a part-time job.
- It is about as far from Australia as you can get: ~16 hours flying, a 15, 17 hour time-zone gap that inverts your working day against AEST, and A$2,500 flights making "quick trips home" neither quick nor cheap.
- The cost of living is roughly half of Sydney, but so are local salaries; this is a destination for imported income, not for building a local career.
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.
