Oman levies no personal taxes and withholds no income tax of any sort. However, the IMF is advising many Middle Eastern countries to introduce tax reforms to diversify their resources.

The lack of direct income taxation makes Oman a great place to save money. Currently, the only taxes expatriates are obliged to pay are the 8% service tax at food and beverage outlets in hotels, a 4% tourism tax, a 5% municipality tax, and a 3% tax on rental accommodation. There is also a tax on alcohol bought at retail shops, and on pork. 

Before leaving your home country to take up an expat posting, you should contact the tax authorities to ensure that you are complying with the financial laws there. Most countries will consider you not liable for income tax once you prove that you are not resident in that country. But you might still have to pay tax on any income you are getting from your home country (for example if you are renting out your property or earning interest on a bank account).
