📊 Hydrocarbon Income Tax Rate Brackets
The tax rate is determined based on the taxpayer’s investment base—a measure of the company’s capital investment in Saudi hydrocarbon operations. According to the Hydrocarbon Income Tax Law:
| Investment Base (SAR) | Tax Rate |
|---|---|
| Above 375 billion | 50% |
| 300 billion – 375 billion | 65% |
| 225 billion – 300 billion | 75% |
| Below 225 billion | 85% |
This progressive rate structure is designed to ensure higher contributions from entities with smaller investment bases while incentivizing larger capital investments.
⚙️ How is the Investment Base Calculated?
The investment base is calculated according to specific rules laid out by ZATCA and generally includes:
- Share capital invested in Saudi hydrocarbon operations.
- Retained earnings and reserves related to upstream activities.
- Net fixed assets used in production.
- Adjustments for debt, advances, and intangible assets.
📋 Example Calculation
Suppose an oil company has an investment base of SAR 250 billion:
- Applicable tax rate: 75% (since it falls between SAR 225 billion and SAR 300 billion)
- Hydrocarbon taxable income: SAR 100 billion
- Hydrocarbon Income Tax = 100 billion × 75% = SAR 75 billion
⚠️ Compliance and Penalties
Companies subject to the Hydrocarbon Income Tax must:
- File annual hydrocarbon tax returns via the ZATCA e-portal.
- Maintain detailed investment base and income documentation.
- Pay the tax liability by the statutory due date to avoid penalties.
Penalties for non-compliance may include fines, interest on late payments, and restrictions on operational licenses.
💡 Tax Planning Tips for Hydrocarbon Companies
- Increase your investment base to qualify for lower tax brackets.
- Leverage joint ventures to share costs and optimize tax efficiency.
- Seek professional tax advisory to interpret ZATCA guidelines.
- Use accelerated depreciation where allowed to adjust taxable income.
🏁 Conclusion
The Hydrocarbon Income Tax structure in Saudi Arabia is unique, with high rates ranging from 50% to 85%. For oil and gas operators, understanding how these brackets work—and how the investment base affects the applicable rate—is critical for compliance and long-term profitability.
