The UAE Corporate Tax (CT) regime — introduced under Federal Decree-Law No. 47 of 2022 — is now fully in effect for the vast majority of UAE businesses. For financial years beginning on or after June 1, 2023, UAE-resident companies and foreign entities with a Permanent Establishment (PE) in the UAE must register, file, and pay Corporate Tax. This guide walks UAE SMEs through every step of the process for the 2026 filing cycle.
📅 Key Deadline: Corporate Tax returns must be filed within 9 months of the end of your financial year. For a December 31, 2025 year-end, your CT return and payment are due by September 30, 2026.
1. Who Must Register for UAE Corporate Tax?
All juridical persons (companies, LLCs, FZEs, etc.) incorporated or established in the UAE, and foreign juridical persons with a UAE Permanent Establishment, are required to register for Corporate Tax with the Federal Tax Authority (FTA). This includes:
- UAE mainland companies (LLCs, PJSCs, sole establishments)
- Free Zone entities — even if they qualify for the 0% Free Zone rate
- Foreign companies with a UAE branch or Permanent Establishment
- Natural persons (individuals) who earn AED 1 million+ in business income per calendar year
⚠️ Free Zone entities MUST still register even if they qualify for the 0% Qualifying Free Zone Person (QFZP) rate. Failure to register can forfeit the 0% benefit and attract penalties.
2. Understanding the UAE Corporate Tax Rates
UAE Corporate Tax applies at two headline rates, with special treatment for Free Zones:
| Taxable Income | CT Rate | Applies To |
|---|---|---|
| AED 0 – AED 375,000 | 0% | All taxable persons (Small Business Relief threshold) |
| Above AED 375,000 | 9% | All taxable persons (mainland) |
| Qualifying Income | 0% | Qualifying Free Zone Persons on qualifying income |
| Non-Qualifying Income | 9% | Free Zone entities on non-qualifying income |
✅ Small Business Relief: SMEs with revenue ≤ AED 3 million per tax period can elect for Small Business Relief, treating their taxable income as AED 0 for that period. This relief is available for tax periods ending on or before December 31, 2026.
3. Step-by-Step: How to Register for UAE Corporate Tax
Step 1 — Access EmaraTax
Go to emaratax.gov.ae and log in using your UAE Pass credentials (or register as a new user). This is the FTA's unified online portal for all tax registrations, filings, and payments.
Step 2 — Register Your Entity
- Click on "Corporate Tax" from the dashboard, then "Register for Corporate Tax"
- Select your entity type (UAE Resident Juridical Person, Natural Person, etc.)
- Enter your Trade License number, Licence Authority, and Licence Expiry Date
- Provide financial year start/end dates and accounting basis (accrual recommended)
- Upload supporting documents: Trade License copy, Memorandum of Association, Passport/Emirates ID of authorized signatories
- Submit — the FTA will issue a Tax Registration Number (TRN) within 20 business days
💡 Pro Tip: Register immediately — penalties for late CT registration start at AED 10,000. The FTA set various registration deadlines based on licence issuance date. When in doubt, register now.
4. Calculating Taxable Income for UAE SMEs
Taxable income is your accounting net profit (prepared under IFRS or IFRS for SMEs) adjusted for specific CT add-backs and deductions. Here are the most common adjustments SMEs must make:
| Adjustment Type | Description | Add-Back / Deduct |
|---|---|---|
| Entertainment Expenses | 50% of entertainment costs are disallowed | Add back 50% |
| Fines & Penalties | Government fines are non-deductible | Add back 100% |
| Dividends Received | UAE dividends from UAE residents are exempt | Deduct (exempt) |
| Donations to Non-approved charities | Non-approved donations are disallowed | Add back 100% |
| Interest Expense | Subject to 30% EBITDA cap (General Interest Deduction Limitation Rule) | Review carefully |
| Depreciation | Tax depreciation must align with CT rules | Adjust if needed |
| Owner Salaries (Sole Est.) | Reasonable market-rate salaries to owner are deductible | Deductible |
5. Filing Your Corporate Tax Return
The CT return is filed electronically through EmaraTax. You have 9 months from the end of your financial year (tax period) to file and pay. Here is the step-by-step filing process:
- Log in to EmaraTax → Corporate Tax → File Return
- Select the relevant Tax Period
- Enter your financial statements data (Revenue, Gross Profit, Net Profit before Tax)
- Input all CT adjustments (disallowed expenses, exemptions, relieved income)
- Apply Small Business Relief if eligible (revenue ≤ AED 3M)
- Calculate taxable income and tax payable at 9% on amount above AED 375,000
- Upload your audited financial statements (mandatory for revenue above AED 50M)
- Review the return summary and submit
- Pay the tax due via EmaraTax (bank transfer, card or GIBAN)
6. Key UAE Corporate Tax Deadlines for 2026
| Financial Year End | CT Return & Payment Due | Notes |
|---|---|---|
| 31 May 2024 | 28 February 2025 | First-ever CT filers — already due |
| 31 December 2024 | 30 September 2025 | Calendar-year companies |

⚠️ Late Filing Penalties: AED 500/month for the first 12 months, then AED 1,000/month thereafter. Late payment attracts 14% p.a. (1.5% monthly) on the unpaid amount. File on time — always.

9. Frequently Asked Questions: UAE Corporate Tax 2026
Is there corporate tax in UAE free zones?
Yes — all Free Zone entities must register for CT. However, Qualifying Free Zone Persons (QFZPs) can benefit from a 0% CT rate on their "Qualifying Income." To qualify, the entity must maintain adequate substance in the UAE, derive income from qualifying activities, and meet minimum revenue requirements. Income from mainland UAE customers may be taxed at 9%.
What is the Small Business Relief threshold for UAE CT?
SMEs with annual revenue of AED 3 million or less can elect Small Business Relief. This treats taxable income as AED 0 for that tax period — effectively a full exemption at the CT level. Both conditions must apply: revenue ≤ AED 3M AND the entity is not part of a multinational group.
Do I need audited financial statements to file UAE CT?
Audited financial statements are mandatory for companies with annual revenue exceeding AED 50 million, or those that are part of a multinational group. For smaller SMEs (revenue < AED 50M), compiled or reviewed statements are generally sufficient, but keeping proper IFRS-based records is always required.
Can I deduct VAT paid as a CT expense?
Irrecoverable VAT (input VAT that cannot be reclaimed from the FTA) is generally deductible as a business expense for CT purposes. Recoverable VAT that has been or will be refunded is not deductible.
