Who Must Register for UAE Corporate Tax?
UAE Corporate Tax (CT) applies to all UAE-incorporated companies, foreign companies with a permanent establishment in the UAE, and individuals conducting business activities in the UAE under a trade licence or permit.
This means: if you have a Dubai Mainland LLC, a free zone company, a sole establishment, or a partnership — you are within scope. There is no turnover threshold for registration. You must register regardless of profit level.
Critical: CT registration and filing are two separate obligations. Even if your profits are below the taxable threshold, you must still register with the FTA and file a Corporate Tax return every year.
What Counts as Taxable Income?
Taxable income is your accounting net profit (prepared under IFRS or an accepted accounting standard), with specific adjustments required by UAE CT law. Key adjustments include:
- Add back: Non-deductible expenses (entertainment above 50% of actual cost, fines & penalties, personal expenses mixed with business)
- Deduct: Qualifying dividends received from UAE and qualifying foreign subsidiaries
- Exempt income: Capital gains on qualifying shareholdings (Participation Exemption)
- Carry forward losses: Tax losses can be offset against up to 75% of future year taxable income
Watch out: Interest deductibility is capped at 30% of EBITDA under the General Interest Limitation Rule. Businesses with significant loan financing need to model this carefully.
The 9% Rate — What Applies and What Doesn't
| Income Level | Tax Rate | Notes |
|---|---|---|
| Taxable income up to AED 375,000 | 0% | Applies to all businesses — the first AED 375K is always tax-free |
| Taxable income above AED 375,000 | 9% | Standard rate on the amount above AED 375K only |
| Qualifying Free Zone Person income | 0% | Only on qualifying income — non-qualifying income taxed at 9% |
| Multinational Groups (Pillar Two) | 15% minimum | Applies when global turnover exceeds EUR 750M |
Free Zone Exemptions — The Real Rules
Free zone companies do NOT automatically get 0% Corporate Tax. To qualify for 0% as a Qualifying Free Zone Person (QFZP), you must meet ALL of the following conditions simultaneously:
- Maintain adequate substance in the free zone (real office, employees, decision-making)
- Earn only qualifying income (income from other free zone entities, exports, qualifying intellectual property)
- Non-qualifying income must not exceed the lower of: 5% of total revenue OR AED 5 million
- Prepare and maintain audited financial statements
- Comply with UAE transfer pricing rules on related party transactions
Common mistake: Many free zone companies earn income from UAE mainland clients. This is non-qualifying income. If it exceeds the 5%/AED 5M threshold, the entire entity loses QFZP status and pays 9% on ALL income for that year.
Small Business Relief — Who Qualifies?
If your business revenue is below AED 3 million for the relevant tax period AND you elect for Small Business Relief, your entire taxable income is treated as zero — effectively 0% tax regardless of profit.
This relief is available for tax periods ending on or before 31 December 2026. You must still register and file a CT return — but you elect for SBR in the return itself.
Important: Small Business Relief is not available to members of multinational enterprise groups or qualifying free zone persons. You can only elect for it if you are a standalone UAE business below AED 3M revenue.
Key Deadlines You Must Not Miss
| Obligation | Deadline | Penalty for Missing |
|---|---|---|
| CT Registration | Within 3 months of licence issue / start of business activity | AED 10,000 |
| CT Return Filing | 9 months after end of financial year | AED 500–20,000+ depending on delay |
| CT Payment | Same date as return filing | Monthly late payment penalty |
| Transfer Pricing Disclosure | With CT return | AED 10,000–50,000 |
| Master File / Local File | Within 12 months of year end (if applicable) | AED 20,000+ |
"I didn't know I was already two years late on CT registration."
Khalid runs a trading company in IFZA Free Zone with AED 4.2M annual revenue. When he came to BookLean in early 2025, he believed his free zone status meant he had no Corporate Tax obligations. We found he had never registered with the FTA, his financial years were wrong for CT purposes, and his sales to UAE mainland clients exceeded the 5% threshold — meaning he didn't qualify for QFZP 0% status anyway. We registered him, restructured his client contracts, filed his first CT return correctly, and got him compliant before the FTA identified the breach. He avoided AED 30,000+ in penalties.
