Income Tax Around the World Compared With the UAE
The UAE has no personal income tax, but it has VAT and corporate tax. How top income tax rates in Japan, Austria, the UK, Australia and the US really work.
"No income tax" is one of the first things people mention about the UAE. It is true for salaries, and it is a real advantage. But it is often explained badly — both what the UAE does tax, and how other countries' rates actually work.
What the UAE does and does not tax
According to the UAE government portal:
- No personal income tax on employment income for individuals.
- VAT at 5% on most goods and services.
- Corporate tax, generally at 9% on taxable profits above a threshold, introduced in 2023, with specific rules for free zones and small businesses.
- Excise tax on certain products such as tobacco and sugary drinks.
- Various fees — housing fees tied to rent in some emirates, municipality charges, government service fees and property registration fees.
So life in the UAE is not tax-free; the burden simply falls differently, and mostly not on salary.
Top marginal rates elsewhere — read with care
The figures below are headline top marginal rates on employment income for residents, as published for recent tax years. They are the rate on the last dirham, pound or yen above the highest threshold — not on the whole income.
| Country | Headline top rate | What sits behind it |
|---|---|---|
| Japan | 45% national | Plus local inhabitant tax of about 10% and a small reconstruction surtax, so combined top rates are in the mid-50s |
| Austria | 55% | The top bracket applies only to income above €1 million; most high earners pay 48–50% at the margin |
| United Kingdom | 45% | Additional rate above £125,140 in England, Wales and Northern Ireland; Scotland has its own bands with a higher top rate; personal allowance is withdrawn at high incomes |
| Australia | 45% | Plus a 2% Medicare levy for most residents |
| United States | 37% federal | Plus state and sometimes city income taxes, which vary from zero to double digits |
Every one of these systems has allowances, deductions, credits and social contributions that change the final number. Comparing headline rates alone tells you about the top of the scale, not about what a typical professional pays.
Marginal is not effective
If someone in the UK earns £200,000, the 45% rate applies only to the slice above £125,140. The rest is taxed at lower rates, or not at all. Their effective rate — total income tax divided by total income — is well below 45%. The same logic applies everywhere. Videos that say "in the UK they take 45% of your salary" overstate it.
Moving does not always end obligations at home
Several countries tax based on citizenship or residence history, or keep you in their system for some time after you leave. The United States taxes its citizens on worldwide income regardless of where they live. Other countries have exit rules, deemed-residence tests or tie-breaker rules in tax treaties. If you move to the UAE, you need to understand how your home country decides when you stop being resident — and get a certificate of tax residence in the UAE if you will rely on a treaty.
British readers should also read our note on UK inheritance tax and UAE property, because inheritance tax follows different rules from income tax.
My take
The UAE's tax model is genuinely attractive for salaried professionals, and I would not pretend otherwise. But I see clients make two mistakes: overstating what they pay at home, and underestimating how long the home country's rules can follow them. A short session with an adviser before the move is cheap insurance. And when you build a budget here, remember that rents and school fees often replace income tax as the big line items — see our cost of living budget.
