Oman is set to become the first country in the Gulf Cooperation Council to introduce a personal income tax — a historic shift for a region long defined by its zero-income-tax environment. The draft law, approved by Oman's State Parliament in July 2024, is widely expected to receive final endorsement from the State Council, the legislature's upper chamber.
What the Oman Personal Income Tax Proposes
The draft law sets tax rates between 5% and 9%, applied differently depending on residency and nationality.
For Omani citizens, a flat 5% rate applies on net global income exceeding one million US dollars. For expatriate residents, the threshold is significantly lower: incomes above $100,000 will be subject to taxation. The first $100,000 of expatriate income remains exempt.
The tiered structure reflects Oman's dual goal of generating new non-oil revenue while limiting the competitive disadvantage of taxing lower-income foreign workers.
Will Other GCC Countries Follow?
The GCC's broader tax landscape is unlikely to shift immediately. Mazen Salhab, chief market strategist for MENA at BDSwiss, noted that Saudi Arabia and the United Arab Emirates have no current plans to introduce income taxes. The risk for Oman is a talent-attraction disadvantage: competing with fully tax-free neighbours for skilled expatriates, international professionals, and global businesses is a genuine challenge.
Still, analysts say the pressure to diversify government revenues is building across the region, and Oman's move could reshape the long-term calculus for other GCC states.
Oman's Fiscal Turnaround Under Sultan Haitham
The rationale behind Oman's decision reflects a broader fiscal reform story. Like Bahrain, Oman had accumulated high public debt — its debt-to-GDP ratio reached 69.6% in 2020. Structural spending cuts initiated under Sultan Haitham bin Tariq Al Said have since driven that ratio down to approximately 35%, according to Capital Economics.
Oman introduced a 5% value-added tax on goods and services in 2021 as part of the same austerity programme. The new personal income tax is projected to contribute only 0.2% of GDP by 2026, according to Fitch Ratings — a modest direct impact, but a meaningful signal of fiscal intent.
The broader results speak for themselves: Oman has moved from a fiscal deficit of nearly 20% of GDP in early 2021 to a surplus of around 2.5% in 2023.
A Defining Moment for Gulf Tax Policy
This GCC-first income tax reform represents a critical milestone in Oman's long-term economic diversification strategy. By broadening its revenue base beyond hydrocarbons, Oman is building the financial resilience needed for sustained growth — even as neighbouring states continue to compete on a zero-tax basis.
