How UAE Corporate Tax Works: The 9% Rate Explained
The UAE introduced federal corporate tax effective 1 June 2023, fundamentally changing the tax landscape for businesses operating in the Emirates. At a rate of 9% on taxable income exceeding AED 375,000, it remains one of the most competitive corporate tax rates globally. But understanding how to calculate your liability correctly—and how to take advantage of the AED 375,000 zero-rate threshold—is essential for every business owner.
Before corporate tax, the UAE was known as a zero-tax jurisdiction for most businesses. That era has ended. Whether you operate a mainland LLC, a free zone entity, or a branch of a foreign company, corporate tax now applies to your business profits. The Federal Tax Authority (FTA) oversees registration, filing, and enforcement, and penalties for non-compliance are significant.
This guide walks you through the corporate tax calculation step by step, explains who must register, covers free zone qualifying income rules, and provides real AED examples so you can estimate your own tax liability. You will also learn about deductible expenses, common mistakes, and how to use SmallERP's tools to stay on top of your obligations.
Understanding the Corporate Tax Structure
UAE corporate tax structure - understanding the 9% rate and AED 375,000 threshold
UAE corporate tax uses a two-tier rate structure that benefits small businesses directly:
- 0% on taxable income up to AED 375,000
- 9% on taxable income above AED 375,000
This means every business effectively gets the first AED 375,000 of annual profit tax-free. Only the amount above this threshold is taxed at 9%.
Taxable income is your accounting profit (revenue minus expenses) adjusted for certain items specified in the corporate tax law. The starting point is your financial statements prepared under IFRS or applicable accounting standards.
Here is how the tax brackets work in practice:
| Annual Taxable Income | Tax on First AED 375,000 | Tax on Amount Above AED 375,000 | Total Tax |
|---|---|---|---|
| AED 200,000 | AED 0 | N/A | AED 0 |
| AED 375,000 | AED 0 | N/A | AED 0 |
| AED 500,000 | AED 0 | AED 125,000 × 9% = AED 11,250 | AED 11,250 |
| AED 1,000,000 | AED 0 | AED 625,000 × 9% = AED 56,250 | AED 56,250 |
| AED 2,000,000 | AED 0 | AED 1,625,000 × 9% = AED 146,250 | AED 146,250 |
| AED 5,000,000 | AED 0 | AED 4,625,000 × 9% = AED 416,250 | AED 416,250 |
The calculation formula:
Corporate Tax = (Taxable Income − AED 375,000) × 0.09
If taxable income is AED 375,000 or below, the tax is AED 0.

Step-by-Step Corporate Tax Calculation
Corporate tax compliance requires systematic calculation and record-keeping
Let us walk through a complete example for a Dubai-based trading company.
Step 1: Determine total revenue
The company earns AED 3,200,000 in annual revenue from product sales.
Step 2: Subtract allowable expenses
- Cost of goods sold: AED 1,800,000
- Staff salaries and benefits: AED 480,000
- Office rent: AED 180,000
- Marketing and advertising: AED 95,000
- Utilities and telecommunications: AED 45,000
- Professional services (audit, legal): AED 60,000
- Depreciation on assets: AED 40,000
- Total expenses: AED 2,700,000
Step 3: Calculate accounting profit
Revenue − Expenses = AED 3,200,000 − AED 2,700,000 = AED 500,000
Step 4: Adjust for non-deductible items
Certain expenses are not deductible for corporate tax purposes:
- Fines and penalties: AED 5,000 (add back)
- Entertainment expenses exceeding 50% limit: AED 10,000 (add back)
- Adjusted taxable income: AED 515,000
Step 5: Apply the corporate tax formula
Tax = (AED 515,000 − AED 375,000) × 9% Tax = AED 140,000 × 9% Tax = AED 12,600
The effective tax rate on total income is just 2.4% (AED 12,600 ÷ AED 515,000), demonstrating how the AED 375,000 threshold significantly reduces the actual tax burden for SMEs.

UAE-Specific Rules: Free Zones, Groups, and Exemptions
Free Zone Qualifying Income: Free zone companies can benefit from a 0% corporate tax rate on qualifying income, provided they meet substance requirements and do not make an election to be taxed at the standard rate. Qualifying income generally includes:
- Income from transactions with other free zone entities
- Income from transactions with parties outside the UAE
- Certain other income as specified by the Minister
However, free zone companies earning income from mainland UAE customers (non-qualifying income) will be taxed at the standard 9% rate on that portion. Maintaining clear records that separate qualifying from non-qualifying income is essential.
Small Business Relief: Businesses with revenue of AED 3,000,000 or less can elect for Small Business Relief, which effectively treats their taxable income as zero. This relief is available for tax periods starting on or after 1 June 2023 and applies until 31 December 2026. This is a major benefit for startups and small businesses—even if your profit exceeds AED 375,000, your tax can be zero if total revenue stays under AED 3 million.
| Relief/Exemption | Condition | Tax Rate |
|---|---|---|
| Standard (below threshold) | Taxable income ≤ AED 375,000 | 0% |
| Standard (above threshold) | Taxable income > AED 375,000 | 9% |
| Small Business Relief | Revenue ≤ AED 3,000,000 | 0% (effective) |
| Free Zone Qualifying Income | Meets substance + qualifying criteria | 0% |
| Free Zone Non-Qualifying Income | Mainland customers | 9% |
Tax Groups: UAE resident companies that are part of the same group (with 95%+ ownership) can form a tax group. The parent company files a single return for the entire group, and intra-group transactions are eliminated. This can simplify compliance and allow losses in one entity to offset profits in another.
Exempt Income: Dividends and capital gains from qualifying shareholdings (generally 5%+ ownership in a subsidiary) are exempt from corporate tax. Income earned by UAE government entities, qualifying public benefit organizations, and certain investment funds is also exempt.
Common Corporate Tax Mistakes
Mistake 1: Not registering on time. Every taxable person must register for corporate tax with the FTA, even if they expect zero tax liability. The registration deadline depends on your license issuance date—check the FTA timeline. Late registration penalties start at AED 10,000.
Mistake 2: Ignoring the Small Business Relief election. This relief is not automatic—you must elect it when filing your return. Businesses earning under AED 3 million in revenue who fail to make this election will be taxed normally.
Mistake 3: Claiming non-deductible expenses. Fines, penalties, donations to non-qualifying entities, personal expenses, and 50% of entertainment costs are not deductible. Including them reduces your apparent profit but will be added back during an audit, resulting in penalties and interest.
Mistake 4: Poor record-keeping for free zone income. Free zone companies must clearly segregate qualifying and non-qualifying income. Without proper documentation, the FTA may deny the 0% rate on all income.
Mistake 5: Confusing revenue with taxable income. Many business owners panic when their revenue crosses AED 375,000, thinking they owe tax. The threshold applies to taxable income (profit), not revenue. A company with AED 2 million in revenue but only AED 300,000 in profit owes zero corporate tax.
