Introduction: The Era of UAE Corporate Tax Is Here — Are You Ready?
For decades, the UAE’s reputation as a zero-tax business paradise attracted millions of entrepreneurs and multinationals. That landscape changed permanently on 1 June 2023, when the UAE introduced Federal Corporate Tax (CT) — and in 2026, businesses across the country are navigating their second and third tax years, with many filing for the very first time.
If you own or operate a business in the UAE — whether on the mainland or in a free zone — understanding your corporate tax UAE obligations is no longer optional. Non-compliance carries penalties that can seriously damage your business, while misunderstanding the exemptions could mean paying tax you were never supposed to.
This guide, written by the tax experts at HAS Business Bureau, covers everything you need to know: who is taxable, what the rates are, how free zones are treated, key deadlines, and the most common filing mistakes UAE businesses are making right now.
What Is UAE Corporate Tax?
UAE Federal Corporate Tax is a direct tax on the net profits (taxable income) of businesses and individuals conducting business activity in the UAE. It is governed by Federal Decree-Law No. 47 of 2022 and administered by the Federal Tax Authority (FTA).
The CT regime applies to all businesses across all seven emirates, including Dubai, Abu Dhabi, Sharjah, and the other northern emirates.
For detailed official guidance, refer to the Federal Tax Authority’s corporate tax page.
UAE Corporate Tax Rates (2026)
The UAE corporate tax structure is straightforward:
| Taxable Income | Corporate Tax Rate |
|---|---|
| AED 0 – AED 375,000 | 0% |
| Above AED 375,000 | 9% |
| Large multinationals (Pillar Two) | 15% (on UAE-sourced income for qualifying MNEs with global revenues exceeding EUR 750 million) |
The 0% threshold for the first AED 375,000 of taxable income was designed to protect small businesses and startups, making the UAE’s CT rate among the lowest in the OECD-participating world.
Small Business Relief: Businesses with revenue below AED 3 million may elect for Small Business Relief, treating their taxable income as zero for CT purposes. This relief is available for tax periods ending on or before 31 December 2026. HAS Business Bureau’s tax advisors can assess whether you qualify.
Who Is Subject to UAE Corporate Tax?
The following are considered taxable persons under the UAE CT law:
- UAE-incorporated companies (both mainland and free zone)
- Foreign companies that are effectively managed and controlled from the UAE
- Individuals conducting business activity in the UAE (with annual business income exceeding AED 1 million)
- Permanent establishments of foreign companies in the UAE
Exempt persons (not subject to CT) include:
- UAE government entities and government-controlled entities
- Extractive businesses (oil and gas) — subject to emirate-level taxation only
- Non-extractive natural resource businesses meeting specific conditions
- Qualifying public benefit entities (charities, foundations)
- Qualifying investment funds and pension funds
- Certain UAE-incorporated holding companies meeting specific conditions
Free Zone Companies and Corporate Tax: The Critical Rules You Must Understand
This is where most free zone businesses make expensive mistakes. Being incorporated in a free zone does not automatically exempt you from corporate tax.
Qualifying Free Zone Person (QFZP) Status
A free zone entity can benefit from a 0% corporate tax rate on qualifying income if it meets all of the following conditions:
- Maintains adequate substance in a UAE free zone (real office, employees, management)
- Derives qualifying income — broadly, income from transactions with other free zone persons or from certain qualifying activities (fund management, treasury, holding company functions, manufacturing, etc.)
- Complies with transfer pricing rules and maintains required documentation
- Does not elect to be subject to the standard CT regime
- Has non-qualifying revenue below the de minimis threshold (5% of total revenue or AED 5 million, whichever is lower)
Non-qualifying income — such as income from UAE mainland customers — is taxed at the standard 9% rate (on the portion above AED 375,000).
This is a nuanced area of law that requires specialist advice. The HAS Business Bureau tax consultancy team works specifically with free zone entities to ensure they maximise their qualifying income status and maintain proper documentation.
Key UAE Corporate Tax Deadlines in 2026
Missing CT deadlines triggers automatic penalties. Here is what you need to track:
CT Registration: All businesses were required to register for corporate tax with the FTA. If you have not yet registered, do so immediately — failure to register carries a penalty of AED 10,000.
Tax Period: Most UAE businesses follow a 12-month financial year. The most common year-end dates are 31 December and 31 March. Your CT return and payment are due nine months after the end of your tax period.
| Financial Year End | CT Return & Payment Deadline |
|---|---|
| 31 December 2024 | 30 September 2025 |
| 31 March 2025 | 31 December 2025 |
| 31 December 2025 | 30 September 2026 |
| 31 March 2026 | 31 December 2026 |
Provisional Tax Payment: For larger entities, the FTA may require provisional (advance) tax payments during the year. Your tax advisor will guide you on whether this applies.
How to Calculate Your UAE Corporate Tax (Simplified)
The basic calculation:
Accounting Net Profit (from your audited or approved financial statements)
Less: Exempt Income (e.g., dividends from UAE subsidiaries, qualifying capital gains)
Plus: Non-Deductible Expenses (e.g., entertainment above the 50% cap, fines and penalties, non-business expenses)
= Taxable Income
Apply the Rate:
- 0% on first AED 375,000
- 9% on the remainder
= Corporate Tax Payable
What Expenses Are Deductible?
The UAE CT law broadly allows deduction of expenses that are “wholly and exclusively” incurred for business purposes, including:
- Salaries and employee costs
- Rent and premises costs
- Depreciation and amortisation
- Finance costs (subject to interest limitation rules — 30% of EBITDA cap)
- Professional fees (accounting, legal, consulting)
- Marketing and advertising
- Cost of goods sold
Non-deductible items include:
- Fines, penalties, and bribes
- Personal expenses of shareholders
- Dividends paid to shareholders
- Expenses relating to exempt income
- Entertainment exceeding 50% of the amount incurred
Transfer Pricing: A Growing Area of Risk
If your business transacts with related parties (parent companies, subsidiaries, sister companies, or related individuals), UAE transfer pricing rules require that those transactions are conducted at arm’s length — i.e., on terms that unrelated parties would agree to.
Businesses with related-party transactions must:
- Prepare a Transfer Pricing disclosure form as part of their CT return
- Maintain a Local File (if revenue exceeds AED 200 million or if specific thresholds apply)
- Potentially prepare a Master File (for MNE groups above certain thresholds)
Transfer pricing is one of the most technically complex areas of UAE CT. HAS Business Bureau provides transfer pricing documentation and advisory services.
Loss Carry-Forward and Group Relief
Tax losses generated in a tax period can be carried forward indefinitely and offset against future taxable income (subject to a 75% cap per year). Losses cannot be carried back.
Tax Group Relief: UAE companies that are 95%+ commonly owned can form a Tax Group, allowing intra-group losses to offset intra-group profits, effectively consolidating the group’s CT position. This is particularly beneficial for holding structures and group companies with varying profitability.
Common UAE Corporate Tax Mistakes Businesses Are Making in 2026
Assuming free zone = zero tax: As explained above, the QFZP regime has strict conditions. Many free zone businesses are inadvertently losing their qualifying status without knowing it.
Not maintaining proper financial records: The FTA requires books and records to be kept for 7 years. Businesses without proper accounting systems face significant challenges at filing time.
Missing the registration deadline: Thousands of businesses missed initial CT registration deadlines and paid avoidable penalties. If you are not yet registered, act immediately.
Ignoring related-party transactions: Transactions between shareholders and their companies (loans, service fees, rent) must be documented at arm’s length prices.
Misclassifying expenses: Claiming personal expenses as business deductions is a compliance risk that can trigger FTA audits.
Filing without professional review: The CT return is a legal document filed under penalty of perjury. Errors can trigger additional tax assessments and penalties.
UAE Corporate Tax and VAT: The Interaction
Corporate tax and VAT are separate obligations, but they interact. Your CT taxable income is based on your accounting profit, which reflects VAT-exclusive revenues and costs (since input VAT is reclaimed and output VAT is a collection on behalf of the FTA). However, irrecoverable input VAT (partially exempt businesses) is treated as a business expense and is deductible for CT purposes.

Frequently Asked Questions
Does corporate tax apply to free zones in the UAE? Yes, all UAE free zone companies are within the scope of UAE Corporate Tax. However, companies meeting the Qualifying Free Zone Person conditions can benefit from a 0% rate on qualifying income.
What is the corporate tax rate in the UAE for small businesses? Businesses with revenues below AED 3 million may elect Small Business Relief, treating their taxable income as zero (0% effective rate) for periods ending on or before 31 December 2026.
When is the UAE Corporate Tax return due? The CT return and tax payment are due nine months after the end of your financial year (e.g., 30 September 2026 for a 31 December 2025 year-end).
Are dividends received from a UAE subsidiary taxable? Dividends received from a UAE-resident subsidiary that is subject to CT are generally exempt from CT at the parent company level, avoiding economic double taxation.
Can I deduct salaries paid to shareholders? Yes, provided the salary is commensurate with the work performed and reflects market rates. Excessive salaries may be challenged by the FTA.
Conclusion
UAE Corporate Tax is now a permanent feature of the business landscape, and with second and third year filings due in 2026, the FTA is increasingly scrutinising compliance. Whether you operate a mainland company or a free zone entity, having a clear understanding of your obligations — and engaging qualified professionals early — is the difference between smooth compliance and costly penalties.
