Introduction
UAE Corporate Tax is now an essential compliance requirement for businesses operating in the United Arab Emirates. In 2026, companies must understand the applicable tax rates, registration procedures, filing deadlines and reporting obligations to avoid penalties.
The UAE generally imposes 0% Corporate Tax on taxable income up to AED 375,000 and 9% on taxable income exceeding AED 375,000.
However, businesses must also consider exemptions, Small Business Relief, Free Zone regulations and other compliance requirements.
This guide explains the key UAE Corporate Tax rules for 2026 and what business owners need to do to remain compliant.
1. What Is UAE Corporate Tax?
UAE Corporate Tax is a federal tax imposed on the taxable profits of businesses under Federal Decree-Law No. 47 of 2022, as amended.
The regime applies to financial years beginning on or after 1 June 2023 and is administered by the Federal Tax Authority (FTA).
Corporate Tax generally applies to:
UAE mainland companies
Free Zone companies
Foreign businesses with a taxable presence in the UAE
Individuals conducting business activities above specified thresholds
Unlike VAT, which generally applies to taxable supplies of goods and services, Corporate Tax is calculated on taxable business income.
2. UAE Corporate Tax Rates in 2026
The standard UAE Corporate Tax rates are:
| Taxable income | Tax rate |
|---|---|
| Up to AED 375,000 | 0% |
| Above AED 375,000 | 9% on the excess |
| Qualifying Free Zone income | 0%, subject to conditions |
| Non-qualifying taxable Free Zone income | Generally 9%, subject to applicable rules |
Corporate Tax Calculation Example
A company earns AED 1,000,000 in taxable income.
First AED 375,000: 0% tax
Remaining AED 625,000: 9% tax
Total Corporate Tax payable: AED 56,250
Corporate Tax is based on taxable income rather than total revenue. Adjustments may be required for exempt income, non-deductible expenses and applicable reliefs.
3. UAE Corporate Tax Registration Requirements
Businesses falling within the Corporate Tax regime generally must register with the FTA, even when no Corporate Tax is payable.
Registration applies to mainland companies, Free Zone entities and other taxable persons.
Individuals conducting business activities generally must register when relevant business turnover exceeds AED 1 million in a calendar year.
Corporate Tax Registration Deadlines
Registration deadlines depend on the business’s incorporation date and taxpayer classification.
For UAE resident companies established on or after 1 March 2024, the general deadline under FTA Decision No. 3 of 2024 is three months from incorporation, establishment or recognition.
Different rules apply to older companies, non-residents and natural persons. Businesses should verify the applicable FTA decisions, including subsequent updates.
How to Register for Corporate Tax
Businesses can register through the official EmaraTax portal.
The process generally involves creating an account, selecting Corporate Tax registration, entering company details, uploading supporting documents and submitting the application.
Once approved, the FTA issues a Corporate Tax Registration Number.
Important: VAT registration does not replace Corporate Tax registration.
4. UAE Corporate Tax Filing Deadlines in 2026
Businesses generally must submit their Corporate Tax returns and pay any tax due within nine months after the end of their financial year, unless a specific exception applies.
| Financial year-end | Filing deadline |
|---|---|
| 31 December 2025 | 30 September 2026 |
| 31 March 2026 | 31 December 2026 |
| 30 June 2026 | 31 March 2027 |
| 31 December 2026 | 30 September 2027 |
For companies following a January-to-December financial year, the Corporate Tax return for 2026 will generally be due by 30 September 2027.
Missing deadlines can result in administrative penalties and additional compliance costs.
Businesses should prepare financial statements and tax calculations well before their filing deadlines.
5. UAE Corporate Tax Exemptions and Small Business Relief
Certain businesses may qualify for Corporate Tax exemptions or reliefs under UAE legislation.
Small Business Relief
Small Business Relief allows eligible resident taxable persons with revenue not exceeding AED 3 million in the relevant and previous tax periods to elect to be treated as having no taxable income, subject to conditions.
In August 2026, the UAE Ministry of Finance announced an extension of Small Business Relief to tax periods ending on or before 31 December 2029.
However, the relief does not apply to Qualifying Free Zone Persons or certain members of large multinational groups.
Eligible businesses must make the appropriate election in their Corporate Tax returns.
Other Exemptions
Depending on statutory conditions, exemptions may apply to certain government entities, qualifying public benefit entities, investment funds, pension funds and natural-resource businesses.
Businesses should confirm their eligibility before assuming an exemption applies.
6. UAE Free Zone Corporate Tax Rules
Free Zone companies are not automatically exempt from Corporate Tax.
A Free Zone company may qualify for a 0% rate on qualifying income if it meets the requirements for a Qualifying Free Zone Person (QFZP).
Key requirements include:
Maintaining adequate substance in the UAE
Generating qualifying income
Complying with transfer pricing rules
Preparing audited financial statements
Meeting applicable qualifying activity and revenue conditions
Non-qualifying income may be subject to Corporate Tax at 9% under the relevant rules.
Free Zone companies must also assess their registration, filing and recordkeeping obligations.
7. UAE Corporate Tax Compliance Requirements
Businesses should maintain proper accounting systems and supporting documents to meet FTA requirements.
Accounting and Recordkeeping
Corporate Tax records generally must be retained for at least seven years after the end of the relevant tax period.
Relevant documents include financial statements, invoices, bank records, contracts, general ledgers and tax computation schedules.
Deductible Expenses
Not all accounting expenses are deductible for Corporate Tax purposes.
Certain fines, penalties, entertainment costs and non-business expenses may be wholly or partially disallowed.
Transfer Pricing
Transactions between related parties and connected persons must comply with applicable transfer pricing requirements, including the arm’s length principle.
Tax Returns and Payments
Businesses generally must submit annual Corporate Tax returns, even where their tax liability is zero.
Late registration, filing, payment or failure to maintain records may result in administrative penalties.
8. UAE 15% Global Minimum Tax in 2026
The UAE introduced a Domestic Minimum Top-up Tax (DMTT) for financial years beginning on or after 1 January 2025.
This regime generally targets multinational groups with consolidated global revenue of at least EUR 750 million in at least two of the preceding four financial years.
It is designed to support a minimum effective tax rate of 15% under the OECD Pillar Two framework.
The 15% regime does not replace the standard 0% and 9% Corporate Tax rates for ordinary UAE businesses.
9. UAE Corporate Tax Compliance Checklist
To prepare for Corporate Tax compliance in 2026, businesses should:
Confirm their Corporate Tax registration status.
Identify the applicable financial year and filing deadline.
Review Small Business Relief or Free Zone eligibility.
Maintain accurate financial statements and accounting records.
Identify deductible and non-deductible expenses.
Review related-party transactions.
Calculate estimated Corporate Tax liabilities.

Regular tax reviews can help businesses avoid penalties and improve financial planning.
