Globally, personal income taxes are a huge source of revenue for governments, but there are some countries where you can be 100 percent certain that you don't have to pay any income tax.

We've put together a list of countries that have no income tax, based on a KPMG survey of 114 nations. Some of the countries are well-known tax havens, while others have managed to use natural resources to fund government expenses.

Let's take a look at 6 beautiful Arab countries with zero income taxes:

1. United Arab Emirates

The UAE has one of the world's highest per-capita incomes at $49,000 with no personal income taxes.

2. Saudi Arabia

Saudi Arabia, the world's biggest oil exporter, doesn't impose a tax on salaries, but self-employed expats are taxed at a rate of 20 percent.

3. Kuwait

While there is no income tax in the country, Kuwaiti nationals must contribute 7.5 percent of their salaries for social security benefits. Their employers make an 11 percent contribution in addition to that.

4. Oman

Just like neighboring Middle Eastern countries in the GCC area, Oman derives the majority of its revenue from crude oil.

5. Qatar

Gas-rich Qatar is the world's richest country with a GDP per capita of $102,800, according to the CIA World Factbook.

6. Bahrain

With no personal income tax, Bahrain relies on output from the Abu Safa oilfield, which is shared with Saudi Arabia, for about 70 percent of its budget revenue.

*And here is a list of non-Arab countries with zero income taxes:

Brunei Darussalam

Brunei Darussalam is the only Asian country to make the list of the nations with zero income taxes.

While there is no income tax in Brunei, employees are required to contribute 5 percent of their wages to a social security trust fund and 3.5 percent to a pension scheme, which are both matched by the employer.

The Bahamas

Among the wealthiest Caribbean countries, the Bahamas features an economy that's heavily dependent on tourism and offshore banking.

About 70 percent of the government revenue comes from duties on imported goods. Even though there is no personal income tax, employees have to contribute 3.9 percent of their salary, up to a maximum of $31,200 annually, for a form of social security called 'National Insurance'.


Considered one of the world's most affluent countries, in terms of costs of living, Bermuda is also known to be one of the world's most expensive nation.

Cayman Islands

Well known as an offshore financial center, the Cayman Islands are a big draw for the wealthy with their zero personal income and capital gains taxes and because they have no mandatory social security contributions.
