UAE corporate tax has been in effect since June 2023, and by now every business owner in the country should know exactly where they stand. This guide breaks down the 2026 rates, who needs to register, how Free Zone companies are taxed, filing deadlines, penalties, and the small print that trips people up most.
What Is Corporate Tax in the UAE?
Corporate tax is a direct tax the UAE government charges on the net profit of businesses. It was introduced under Federal Decree-Law No. 47 of 2022 and has applied to financial years starting on or after 1 June 2023. The goal was straightforward: bring the UAE in line with international tax standards while keeping the system light-touch enough to protect small businesses and startups.
If you run a mainland company, a Free Zone entity, or even operate as a freelancer or sole establishment above a certain turnover, corporate tax almost certainly applies to you in some form, even if your actual bill works out to zero.
UAE Corporate Tax Rates (2026)
The UAE uses a simple, tiered structure rather than one flat rate for everyone:
| Taxable Income / Category | Corporate Tax Rate |
| Up to AED 375,000 | 0% |
| Above AED 375,000 | 9% |
| Qualifying Free Zone Person – Qualifying Income | 0% |
| Qualifying Free Zone Person – Non-Qualifying Income | 9% |
| Large Multinational Groups (Consolidated Revenue ≥ EUR 750 Million) | 15% effective, via Domestic Minimum Top-up Tax |
The AED 375,000 band is a tax-free threshold, not a blanket exemption; you still need to register and file, even if your final liability is nil.
Who Needs to Register for Corporate Tax?
Registration with the Federal Tax Authority (FTA) is mandatory for almost every business structure in the UAE, including:
- Mainland LLCs and other onshore companies
- Free Zone companies, including those that expect to pay 0%
- Branches of foreign companies operating in the UAE
- Natural persons (freelancers, sole establishments) whose UAE turnover crosses AED 1 million in a calendar year
Registration deadlines are tied to your trade licence issue date under FTA Decision No. 3 of 2024, so two companies incorporated a month apart can have different registration windows. Missing the deadline attracts a fixed AED 10,000 administrative penalty, though the FTA currently waives this if your very first corporate tax return is filed within seven months of your first tax period ending.
Free Zone Companies and the 0% Rate
Free Zone businesses remain one of the UAE’s biggest tax advantages, but the 0% rate isn’t automatic. To be treated as a Qualifying Free Zone Person (QFZP), your company generally needs to:
- Maintain adequate substance in the UAE (real staff, assets, or operations, not just a licence on paper)
- Earn qualifying income as defined under the Corporate Tax Law and Cabinet Decision No. 100 of 2023
- Keep audited financial statements
- Comply with transfer pricing rules on related-party transactions
- Not elect out of the QFZP regime
Get any one of these wrong and your Free Zone company’s income (or part of it) can be reclassified as non-qualifying and taxed at the standard 9% rate. Free Zone authorities including IFZA, Meydan and DMCC, now also check your corporate tax status at licence renewal, so this isn’t something to leave until year-end.
Small Business Relief: Who Qualifies
Small Business Relief (SBR) lets eligible resident businesses elect to be treated as having zero taxable income for a tax period, effectively wiping out the corporate tax bill entirely.
| Condition | Requirement |
| Revenue Threshold | AED 3,000,000 or less in the relevant tax period and every prior tax period |
| How It’s Claimed | Elected on the corporate tax return via EmaraTax, it is not automatic |
| Legal Basis | Article 21 of the Corporate Tax Law and Ministerial Decision No. 73 of 2023 |
| Availability Window | Currently scheduled for tax periods ending on or before 31 December 2026 |
If your revenue is close to the AED 3 million mark or you’re unsure whether you still qualify, it’s worth checking before this relief window closes; the rules do not currently extend beyond 2026.
Filing Deadlines and Penalties
Every registered taxable person must file an annual corporate tax return, even businesses in the 0% band, those electing Small Business Relief, and Free Zone companies with full QFZP status. There is no exemption from the filing obligation itself.
| Item | Detail |
| Standard Filing Window | 9 months after the end of your financial year |
| Example (31 Dec 2025 Year-End) | Return and payment both due by 30 September 2026 |
| Late Registration Penalty | AED 10,000 fixed (waivable if the first return is filed within 7 months of the first tax period ending) |
| Late Filing Penalty | AED 500 per month for the first 12 months, then AED 1,000 per month |
| Late Payment | 14% per annum interest on unpaid tax, with no cap |
As of 1 January 2026, Federal Decree-Law No. 17 of 2025 also gave the FTA broader audit powers and tighter procedural deadlines, so the margin for error on late or incomplete filings has narrowed further.
What Counts as Taxable Income?
Your taxable income starts from your accounting net profit (prepared under IFRS, or IFRS for SMEs where revenue is below AED 50 million) and is then adjusted for tax purposes. Common adjustments include:
- Adding back non-deductible items such as fines, penalties and unlawful payments
- Removing exempt income, such as qualifying dividends and participation-exemption gains
- Applying available reliefs, exemptions, and carried-forward losses
Certain entities – government bodies, qualifying public benefit organisations, and regulated investment funds among them, may be fully exempt, though most still need to register and file a zero-liability return to prove it.
Documents You’ll Need to File
- Tax Registration Number (TRN) and FTA registration certificate
- Audited (or unaudited, if revenue is under AED 50 million) IFRS financial statements
- Trade licence, Memorandum/Articles of Association, and other incorporation documents
- Detailed revenue, expense and depreciation records
- Transfer pricing documentation, where related-party transaction thresholds are met
All returns and supporting documents are submitted online through the EmaraTax portal.
Recent Changes to Watch in 2026
- A 15% Domestic Minimum Top-up Tax now applies to UAE entities within multinational groups with consolidated revenue of EUR 750 million or more, under Cabinet Decision No. 142 of 2024
- Federal Decree-Law No. 17 of 2025 rewrote the Tax Procedures Law with tighter FTA deadlines and expanded audit powers, effective 1 January 2026
- Master file and local file transfer pricing documentation is required where group consolidated revenue exceeds AED 3.15 billion, or UAE entity revenue exceeds AED 200 million
- Small Business Relief is currently legislated only through tax periods ending on or before 31 December 2026, businesses relying on it should plan ahead

Frequently Asked Questions
1. Do all businesses in the UAE have to pay corporate tax?
Every business generally needs to register, but not every business ends up paying. Taxable income up to AED 375,000 is taxed at 0%, and eligible small businesses can elect Small Business Relief to bring their liability to zero.
2. What is the corporate tax rate for Free Zone companies?
Free Zone companies that qualify as a Qualifying Free Zone Person pay 0% on qualifying income and 9% on non-qualifying income. Losing QFZP status means the standard 9% rate can apply more broadly.
3. When is the corporate tax return due for the 2025 financial year?
For businesses with a financial year ending 31 December 2025, both the return and any payment due are due by 30 September 2026.
4. What happens if I miss the corporate tax registration deadline?
A fixed AED 10,000 penalty applies. The FTA currently offers a waiver if your first corporate tax return is filed within seven months of the end of your first tax period.
5. Is Small Business Relief permanent?
No. As it currently stands, Small Business Relief is only available for tax periods ending on or before 31 December 2026, so eligible businesses should not assume it will continue indefinitely.
6. Can I file my corporate tax return myself?
Yes, filing is done online via EmaraTax. Many businesses choose to work with a registered tax agent or advisory firm to reduce the risk of errors that trigger FTA penalties or audits.
