The UAE introduced Federal Corporate Tax (CT) effective for financial years starting on or after 1 June 2023. This represents the most significant tax reform in the country's history — and it affects the vast majority of businesses operating in the UAE.
Whether you're a Fujairah SME owner, a Dubai free zone company, or a mainland trading business, this guide covers everything you need to know to stay compliant and plan effectively.
1. What Is UAE Corporate Tax?
UAE Corporate Tax is a direct tax levied on the net income (profits) of businesses at a standard rate of 9%. It is administered by the Federal Tax Authority (FTA) under Federal Decree-Law No. 47 of 2022.
The tax applies to:
- All UAE resident companies (mainland and free zone)
- Foreign companies with a permanent establishment in the UAE
- Individuals earning business income above AED 1 million annually
2. The Key Numbers You Must Know
| Parameter | Value | Notes |
|---|---|---|
| Standard Tax Rate | 9% | On taxable income above AED 375,000 |
| Zero Rate (0%) | 0% | On taxable income up to AED 375,000 |
| Small Business Relief | 0% | Revenue ≤ AED 3 million (until Dec 2026) |
| QFZP Rate | 0% | On qualifying income for free zone entities |
| Multinational Rate | 15% | OECD Pillar Two — revenue ≥ AED 3.15 billion |
3. Free Zone Companies: The Qualifying Income Rules
This is where things get complex. Free zone companies can still enjoy a 0% tax rate on qualifying income — but only if they meet specific conditions under the Qualifying Free Zone Person (QFZP) rules.
To qualify as a QFZP, your company must:
- Maintain adequate substance in the UAE
- Derive qualifying income only (from within the free zone or international sources)
- Not elect to be subject to regular CT
- Comply with transfer pricing rules
- Not earn more than 5% of revenue or AED 5 million from non-qualifying sources
"The 95% rule is critical — free zone companies that unknowingly exceed the 5% non-qualifying income threshold lose their 0% status for the ENTIRE year, not just the excess." — Shaneeb, The Fiscal Crafter
This is why tracking qualifying vs. non-qualifying income throughout the year in a structured Excel tracker is essential, not optional.
4. How to Calculate Your Corporate Tax
The calculation follows this structure:
- Start with accounting profit (from your audited financial statements)
- Add back non-deductible expenses (50% entertainment, fines, penalties, excessive interest)
- Deduct exempt income (dividends from UAE subsidiaries, capital gains on qualifying shares)
- Apply tax losses (from prior years — max 75% of taxable income per year)
- Calculate taxable income (Step 1 ± Steps 2-4)
- Apply the rate: 0% on first AED 375,000 + 9% on the remainder
5. Filing & Payment Deadlines
Filing is done annually through the FTA's EmaraTax portal. Key deadlines:
| Task | Deadline |
|---|---|
| Tax return filing | 9 months after financial year end |
| Tax payment | 9 months after financial year end |
| CT registration | Before the first filing deadline |
For companies with a 31 December financial year end: the first CT return is due by 30 September 2025.
6. How to Prepare Your Excel Records
Good record-keeping isn't just best practice — it's a legal requirement. The FTA can request supporting documentation for any position taken in your tax return.
Essential Excel worksheets to maintain:
- Monthly income statement with revenue categorisation (qualifying/non-qualifying)
- Non-deductible expenses log with supporting rationale
- Transfer pricing documentation (for related party transactions)
- Tax depreciation schedule (separate from accounting depreciation)
- Intercompany loan register (with arm's length interest rates)
Our UAE Corporate Tax Planner includes all 14 of these worksheets pre-built and cross-linked, saving you 40+ hours of setup time.
7. Common Mistakes UAE Businesses Are Making
- Assuming free zone = zero tax automatically — it requires active QFZP compliance
- Not registering on time — FTA penalties apply from the first deadline
- Using accounting depreciation instead of tax depreciation — these differ under UAE CT law
- Ignoring transfer pricing — related party transactions require arm's length documentation
- Mixing personal and business expenses — all expenses claimed must be "wholly and exclusively" for business
Conclusion
UAE corporate tax is here to stay. The businesses that embrace it proactively — with proper record-keeping, structured tax planning and early FTA registration — will avoid penalties and may even find planning opportunities that reduce their effective tax rate.
