RIYADH: Oman will become the first country in the Gulf to impose a personal income tax, as the oil producer works to diversify its revenue stream.

The sultanate will impose a 5-percent levy on taxable income for individuals earning over 42,000 Omani rials ($109,091) per year starting from 2028, according to a royal decree.

The Gulf country added that the tax would apply to about 1 percent of the population.

The move comes after Oman launched a medium-term fiscal program in 2020 to reduce public debt, diversify revenue sources, and spur economic growth, which has improved state finances.

“The law also includes deductions and exemptions that take into account the social situation in the Sultanate of Oman, such as education, health care, inheritance, zakat, donations, primary housing,” the country’s tax authority said in a statement.
