Understanding the United Arab Emirates tax deadlines for 2025/2026 is essential for every business and individual operating in one of the world's most dynamic economies. While the UAE has historically been known as a tax-free haven, the introduction of federal corporate tax in June 2023 and the ongoing Value Added Tax (VAT) regime mean that knowing when to file taxes in the United Arab Emirates is now a critical compliance requirement.
This complete United Arab Emirates tax calendar walks you through every key date, obligation, and filing window you need to know for the 2025/2026 tax period — whether you're a multinational corporation, an SME, a freelancer, or an expatriate living in the Emirates.

Understanding the UAE Tax Landscape in 2025/2026
Before diving into specific deadlines, it's important to understand what taxes actually apply in the United Arab Emirates. The tax environment has evolved significantly in recent years, and 2025/2026 reflects a maturing system that balances the UAE's business-friendly reputation with international transparency standards.
Taxes Currently in Effect
- Federal Corporate Tax (CT): Introduced on June 1, 2023, at a standard rate of 9% on taxable profits exceeding AED 375,000. Profits up to AED 375,000 are taxed at 0%.
- Value Added Tax (VAT): A 5% VAT has been in effect since January 1, 2018, administered by the Federal Tax Authority (FTA).
- Excise Tax: Applied to specific goods deemed harmful to health or the environment (e.g., tobacco, sugary drinks, energy drinks).
- Personal Income Tax: The UAE does not levy a personal income tax on individuals' employment income, investment income, or other personal earnings. This remains one of the most attractive features of the Emirates for expatriates and high-net-worth individuals.
What About Individual Tax Obligations?
While there is no personal income tax in the UAE, individuals who are sole proprietors, freelancers conducting business, or partners in unincorporated partnerships may fall under the corporate tax regime if their business activities exceed the relevant thresholds. Additionally, UAE tax residency certificates — increasingly important under international tax treaties — follow a specific application process with its own timeline.
Key Corporate Tax Deadlines for 2025/2026
The federal corporate tax is the most significant tax compliance obligation for businesses in the UAE. Understanding the filing timeline is essential to avoid penalties.
Corporate Tax Registration Deadlines
The FTA has issued specific registration deadlines based on the type of license a business holds. For the 2025/2026 period:
- Businesses with licenses issued in January or February: Registration deadline was already in 2024. Ensure your registration is active and up to date.
- Businesses with licenses issued between March and December: Most had registration deadlines throughout 2024, but new businesses formed in 2025 must register within the timeframe specified in their FTA notification — typically within 3 months of becoming subject to corporate tax.
- Free Zone entities: Must register regardless of whether they qualify for the 0% Free Zone regime. The same deadline rules apply.
- Non-resident persons with a permanent establishment in the UAE: Must register within 3 months of the existence of the permanent establishment.
Common Mistake: Many Free Zone companies assume they are exempt from registering for corporate tax because they qualify for the 0% rate. This is incorrect — all qualifying Free Zone persons must still register and file returns.
Corporate Tax Return Filing Deadlines
Corporate tax returns must be filed within 9 months from the end of the relevant tax period. Here's how that translates for common financial year-ends:
| Financial Year-End | Tax Period | Filing Deadline |
|---|---|---|
| December 31, 2024 | Jan 1 – Dec 31, 2024 | September 30, 2025 |
| March 31, 2025 | Apr 1, 2024 – Mar 31, 2025 | December 31, 2025 |
| June 30, 2025 | Jul 1, 2024 – Jun 30, 2025 | March 31, 2026 |
| December 31, 2025 | Jan 1 – Dec 31, 2025 | September 30, 2026 |
| March 31, 2026 | Apr 1, 2025 – Mar 31, 2026 | December 31, 2026 |
Payment of corporate tax is due on the same date as the filing deadline — within 9 months of the end of the tax period.
Small Business Relief
For the 2025/2026 tax years, resident taxable persons with revenue of AED 3 million or less may elect for Small Business Relief, which treats them as having no taxable income for the period. However, they must still:
- Be registered for corporate tax
- File a corporate tax return by the standard deadline
- Make the election in the return itself
The AED 3 million threshold applies per tax period and is expected to remain in place through at least tax periods ending on or before December 31, 2026.
VAT Filing Deadlines and Calendar for 2025/2026
VAT compliance follows a regular, recurring schedule that businesses must adhere to throughout the year.
VAT Return Periods
The FTA assigns VAT return periods — either monthly or quarterly — based on a business's annual taxable turnover:
- Monthly filing: Generally for businesses with annual taxable supplies exceeding AED 150 million
- Quarterly filing: For most other VAT-registered businesses
Quarterly VAT Deadlines for 2025
| Quarter | Period Covered | Filing & Payment Deadline |
|---|---|---|
| Q1 2025 | January 1 – March 31, 2025 | April 28, 2025 |
| Q2 2025 | April 1 – June 30, 2025 | July 28, 2025 |
| Q3 2025 | July 1 – September 30, 2025 | October 28, 2025 |
| Q4 2025 | October 1 – December 31, 2025 | January 28, 2026 |
Quarterly VAT Deadlines for 2026
| Quarter | Period Covered | Filing & Payment Deadline |
|---|---|---|
| Q1 2026 | January 1 – March 31, 2026 | April 28, 2026 |
| Q2 2026 | April 1 – June 30, 2026 | July 28, 2026 |
| Q3 2026 | July 1 – September 30, 2026 | October 28, 2026 |
| Q4 2026 | October 1 – December 31, 2026 | January 28, 2027 |
Note: The 28th of the month following the end of the tax period is the standard deadline. If the 28th falls on a weekend or public holiday, the deadline typically extends to the next business day. Always confirm on the FTA's EmaraTax portal.
Monthly VAT Deadlines
For monthly filers, the deadline is the 28th of the month following each tax period. For example:
- January 2025 return → February 28, 2025
- February 2025 return → March 28, 2025
- And so on throughout 2025 and 2026
VAT Registration Thresholds
- Mandatory registration: Annual taxable supplies and imports exceed AED 375,000
- Voluntary registration: Annual taxable supplies and imports (or taxable expenses) exceed AED 187,500
Businesses crossing these thresholds must register within 30 days — a deadline that runs year-round and can catch fast-growing companies off guard.
Excise Tax Deadlines for 2025/2026
Businesses dealing in excise goods (tobacco products, carbonated drinks, energy drinks, sweetened drinks, and electronic smoking devices) must file excise tax returns on a monthly basis.
Key Excise Tax Dates
- Filing frequency: Monthly
- Deadline: The 15th of the month following the end of each tax period
- Example: The excise tax return for January 2025 is due by February 15, 2025
Excise tax rates for 2025/2026 remain:
- 100% on tobacco and tobacco products
- 100% on energy drinks
- 100% on electronic smoking devices and liquids
- 50% on carbonated drinks
- 50% on sweetened drinks
Transfer Pricing and Country-by-Country Reporting Deadlines
With the corporate tax regime now fully operational, transfer pricing compliance is a critical area for multinational enterprises operating in the UAE.
Transfer Pricing Documentation
- Local File and Master File: Must be prepared and available upon request by the FTA. While there is no separate filing deadline, businesses should have documentation ready by the corporate tax return filing deadline (i.e., within 9 months of the financial year-end).
- Disclosure Form: A transfer pricing disclosure form must be submitted as part of the corporate tax return.
Country-by-Country Reporting (CbCR)
UAE-headquartered multinational enterprise groups with consolidated group revenue of AED 3.15 billion (approximately EUR 750 million) or more must file a CbC Report:
- Deadline: Within 12 months of the end of the reporting fiscal year
- Notification: Must be submitted to the FTA by the last day of the reporting fiscal year
For a multinational group with a December 31, 2025 fiscal year-end:
- CbC Notification: Due by December 31, 2025
- CbC Report: Due by December 31, 2026
Tax Residency Certificates and International Obligations
Even without personal income tax, UAE residents may need to manage international tax obligations — especially if they hold assets, investments, or income in countries that do levy personal income tax.
UAE Tax Residency Certificate
A Tax Residency Certificate (TRC) can be applied for through the FTA's EmaraTax portal. This document is essential for:
- Claiming benefits under the UAE's network of over 130 double taxation agreements (DTAs)
- Proving tax residency to foreign authorities
- Meeting Common Reporting Standard (CRS) and FATCA requirements
Eligibility criteria for individuals:
- Physical presence in the UAE for 183 days or more within a consecutive 12-month period, OR
- Physical presence of 90 days or more within a 12-month period combined with having a permanent place of residence or employment in the UAE
Processing time: Typically 5–10 business days
There is no fixed annual deadline, but TRCs are valid for one year from the date of issuance and must be renewed as needed.
Practical Example: Expat With Foreign Income
Consider Sarah, a British expatriate working in Dubai. She earns AED 500,000 annually from her employer and also receives rental income from a property in the UK. While her UAE salary is not taxed in the UAE, she may need to:
- Obtain a UAE TRC to claim treaty benefits on her UK rental income
- File a UK tax return declaring the rental income and claiming relief under the UK-UAE Double Taxation Agreement
- Potentially register for corporate tax if she conducts any freelance business from the UAE

Penalties for Late Filing and Non-Compliance
The FTA takes compliance seriously, and the penalties for missing UAE tax deadlines in 2025/2026 can be substantial.
Corporate Tax Penalties
- Late registration: AED 10,000
- Late filing of tax return: AED 500 per month for the first 12 months, then AED 1,000 per month thereafter (up to a maximum of AED 24,000 per return)
- Late payment of tax: A percentage-based penalty applied monthly on the outstanding amount
- Failure to maintain records: AED 10,000 for the first violation, AED 20,000 for repeat violations within 24 months
VAT Penalties
- Late registration: AED 10,000
- Late filing: AED 1,000 for the first offense, AED 2,000 for a repeat offense within 24 months
- Late payment: A 2% penalty immediately on the outstanding amount, then 4% monthly thereafter (capped at 300% of the tax due)
- Filing an incorrect return: A penalty based on the percentage of the net error, potentially reaching AED 50,000 for repeated errors
How to Avoid Penalties
- Set calendar reminders for all filing and payment deadlines at least 2–4 weeks in advance
- Maintain organized financial records throughout the year — don't leave bookkeeping until deadline season
- Use the EmaraTax portal regularly to check for any FTA notifications or deadline updates
- Engage a qualified tax agent if your affairs are complex, especially for first-time corporate tax filings
- File early — there is no advantage to filing on the last possible day, and system overloads near deadlines can cause technical delays
Frequently Asked Questions (FAQ)
Do individuals need to file tax returns in the UAE?
No. The UAE does not impose personal income tax, so there is no individual income tax return to file. However, individuals conducting business activities (freelancers, sole proprietors) may need to file corporate tax returns if their activities fall within the scope of the CT law.
When is the corporate tax return due for a business with a December 2025 year-end?
The corporate tax return is due within 9 months of the end of the tax period, so for a December 31, 2025 year-end, the filing and payment deadline is September 30, 2026.
Do Free Zone companies need to file corporate tax returns?
Yes. Even if a Free Zone entity qualifies for the 0% corporate tax rate, it must still register for corporate tax and file an annual return by the standard deadline.
What happens if I miss a VAT filing deadline?
You will incur a penalty of AED 1,000 for the first late filing and AED 2,000 for any subsequent late filing within 24 months. Late payment penalties are also charged separately.
Can I get an extension on my corporate tax filing deadline?
As of 2025, the FTA has not introduced a formal extension mechanism for corporate tax return deadlines. Businesses are expected to file within the 9-month window.
Does the UAE have tax treaties that affect my obligations?
Yes. The UAE has signed over 130 double taxation agreements with countries worldwide. These treaties can affect the withholding tax rates on certain payments and may require you to obtain a Tax Residency Certificate. Always review the specific treaty relevant to your situation.
