UAE corporate tax deadlines 2026–2027. DMTT/Pillar Two registration due 30 November 2026. Complete calendar of corporate tax filing, VAT returns, top-up tax and penalty deadlines for UAE businesses.
If you run a business in the UAE, missing a tax deadline isn’t just inconvenient — it’s expensive. With the Federal Tax Authority (FTA) now enforcing penalties at 14% per annum on late payments under Cabinet Decision No. 129 of 2025 and flat fines of up to AED 10,000 for late registrations, staying on top of every due date is no longer optional.
And right now, one deadline demands your immediate attention: 30 November 2026 — the registration cut-off for the UAE’s new Domestic Minimum Top-up Tax (DMTT) under Pillar Two. If your multinational group has consolidated revenue of EUR 750 million or more, this may apply to you.
This guide covers the critical UAE corporate tax deadlines for 2026 and 2027, explains who the DMTT affects, and shows you how to stay compliant.
What Is the UAE Corporate Tax Deadline Calendar?
The UAE corporate tax deadline calendar covers several distinct obligations under Federal Decree-Law No. 47 of 2022 and related legislation.
Unlike jurisdictions with a single annual filing date, UAE businesses must track deadlines for:
- Corporate tax registration.
- Corporate tax return filing.
- Corporate tax payments.
- VAT returns.
- Pillar Two top-up tax registration and reporting.
Each obligation carries its own timeline, penalty schedule and compliance requirements.
The most significant addition to this calendar is the Qualified Domestic Minimum Top-up Tax (QDMTT), introduced by Cabinet Decision No. 142 of 2024. It implements the OECD/G20 Pillar Two framework and affects large multinational enterprises operating in or through the UAE.
The registration deadline of 30 November 2026 applies to entities whose first in-scope fiscal year ended before 30 April 2026.
Who Does This Apply To?
The UAE corporate tax deadline calendar applies to different categories of taxpayers.
1. All UAE Businesses Subject to Corporate Tax
This includes mainland companies, free zone entities, branches of foreign companies and natural persons with annual turnover exceeding AED 1,000,000 under Cabinet Decision No. 49 of 2023.
These taxpayers must comply with applicable corporate tax registration, annual return filing and payment deadlines.
2. VAT-Registered Businesses
Businesses whose taxable supplies and imports exceed the mandatory registration threshold of AED 375,000 must comply with quarterly or monthly VAT return filing obligations.
VAT returns generally follow the 28th-day filing rule.
3. Large Multinational Enterprises (DMTT/Pillar Two)
UAE entities belonging to multinational enterprise groups with consolidated annual revenue of EUR 750 million or more in at least two of the four preceding fiscal years must consider separate top-up tax registration.
This may include:
- UAE constituent entities.
- Permanent establishments.
- Joint ventures.
- Free zone entities.
- Flow-through entities.
Purely domestic UAE groups fall outside the DMTT scope, regardless of their size.
4. Qualifying Free Zone Persons (QFZPs)
QFZPs distributing revenue between qualifying and other activities may have an additional reporting obligation.
Under FTA Decision No. 6 of 2026, an AUP Report (ISRS 4400 Revised) must be submitted within 30 days of corporate tax return filing, where the requirement applies.
Key UAE Corporate Tax Rules, Deadlines and Requirements
1. Corporate Tax Registration Deadlines
Every taxable person must register for corporate tax through the EmaraTax portal.
The FTA has established specific registration deadlines based on licence issuance dates and other applicable requirements.
Late corporate tax registration carries a flat administrative penalty of AED 10,000.
Businesses that have not completed their registration should review their applicable deadlines immediately.
2. Corporate Tax Return Filing and Payment
Your corporate tax return must be filed within 9 months from the end of the relevant tax period.
For businesses following a standard 1 January to 31 December financial year, the filing and payment deadline is 30 September of the following year.
Late filing penalties under the current regime include:
- AED 500 per month for the first 12 months of delay.
- AED 1,000 per month for each subsequent month.
Late payment attracts 14% per annum on the outstanding amount, effective 14 April 2026 under Cabinet Decision No. 129 of 2025.
This makes timely tax payment particularly important.
3. DMTT / Pillar Two Registration – 30 November 2026
One of the most important upcoming UAE tax deadlines is the DMTT registration deadline.
Under FTA Decision No. 12 of 2026, qualifying UAE entities must register for top-up tax through EmaraTax.
Key requirements include:
- General deadline: Registration within 7 months after the end of the entity’s first in-scope fiscal year.
- Transitional deadline: Entities whose first in-scope fiscal year ended before 30 April 2026 must register by 30 November 2026.
- Late registration penalty: AED 10,000 per entity.
- Revenue threshold: EUR 750 million in consolidated group revenue in at least two of the four preceding fiscal years.
- Entities in scope: UAE constituent entities, permanent establishments, joint ventures and flow-through entities, including free zone entities.
- Excluded groups: Purely domestic UAE groups, government bodies, non-profits, pension funds and certain investment entities.
The EUR 750 million threshold is measured using the Ultimate Parent Entity’s consolidated financial statements, not the individual UAE entity’s revenue.
4. Pillar Two Information Return and Top-up Tax Return
Following registration, in-scope entities face two additional filing obligations.
Top-up Tax Return:
Generally due within 15 months of the fiscal year-end, extended to 18 months for the first Transition Year.
For a 31 December 2025 year-end, the deadline is 30 June 2027.
Pillar Two Information Return:
A separate filing obligation under Ministerial Decision No. 133 of 2026, also generally due within 15 months.
Both obligations must be considered when planning Pillar Two compliance.
The top-up tax aims to ensure a minimum 15% effective tax rate on the UAE profits of qualifying multinational groups.
The calculation follows:
ETR = Adjusted Covered Taxes ÷ Net Pillar Two Income
If the effective tax rate falls below 15%, the UAE collects the applicable difference under the top-up tax framework.
5. VAT Return Deadlines
VAT returns are generally due by the 28th day after the end of each tax period.
Most businesses filing quarterly VAT returns must meet four filing deadlines each year.
Late VAT registration carries a penalty of AED 10,000, while late filing and payment are subject to their respective administrative penalty rules.
6. Other Important UAE Tax Dates for 2026–2027
Businesses should also monitor the following obligations:
- QFZP AUP Report: Within 30 days of corporate tax return filing, where applicable.
- Transitional Relief Election: Must be made in the first corporate tax return under Ministerial Decision No. 120 of 2023.
- Transfer Pricing Documentation: Master File and Local File requirements should be assessed and documentation prepared contemporaneously, where applicable.
- Country-by-Country Reporting: Applies to qualifying groups with consolidated revenue of AED 3.15 billion or more.
- E-Invoicing Phase 1: January 2027 for businesses with annual turnover above AED 50 million.
Step-by-Step Guide: Meeting the 30 November DMTT Deadline
With the registration deadline approaching, businesses belonging to potentially qualifying multinational groups should take the following steps.
Step 1 – Confirm Group Revenue
Review the Ultimate Parent Entity’s consolidated financial statements for the four fiscal years preceding the relevant period.
If consolidated revenue reached EUR 750 million in at least two of those years, the UAE entities may fall within the DMTT scope.
Step 2 – Map All UAE Entities
Prepare a complete list of all UAE entities within the multinational group, including:
- Subsidiaries.
- Branches.
- Permanent establishments.
- Joint ventures.
- Flow-through entities.
Free zone status does not automatically exempt an entity from DMTT obligations.
Step 3 – Classify Each Entity
Determine whether each entity qualifies as a constituent entity, excluded entity or investment entity.
Review applicable transitional rules and elections.
Step 4 – Calculate Each Entity’s Registration Deadline
Apply the seven-month rule from the end of the first in-scope fiscal year.
If the first in-scope fiscal year ended before 30 April 2026, the transitional registration deadline is 30 November 2026.
Step 5 – Decide on the Filing Structure
Determine whether each entity will register individually or whether the group will appoint a Domestic Designated Filing Entity (DDFE).
The group should also identify its Designated Local Entity (DLE) for the Pillar Two Information Return.
Step 6 – Secure EmaraTax Access
Ensure that authorised signatories have active UAE Pass credentials and access to EmaraTax.
Where a DDFE files for multiple entities, the necessary authorisations should be documented.
Step 7 – Submit and Maintain Records
Complete the registration through EmaraTax.
Save the confirmation receipts for each entity and record the subsequent Pillar Two filing deadlines.
Common UAE Tax Compliance Mistakes to Avoid
1. Assuming Corporate Tax Registration Covers DMTT
Corporate tax registration and DMTT registration are separate obligations.
Having a corporate tax TRN does not automatically satisfy Pillar Two registration requirements.
2. Testing UAE Revenue Instead of Group Revenue
The EUR 750 million threshold relates to the multinational group’s consolidated global revenue, not the individual UAE company’s turnover.
A UAE subsidiary with AED 5 million in revenue may still fall within the DMTT scope if its parent group meets the threshold.
3. Applying 30 November 2026 to Every Entity
The transitional deadline applies specifically to entities whose first in-scope fiscal year ended before 30 April 2026.
Entities with later year-ends may have different deadlines. For example, an entity with a June 2026 year-end has until 31 January 2027 under the seven-month rule.
4. Overlooking Permanent Establishments and Joint Ventures
Permanent establishments and joint ventures within qualifying groups must be properly identified and assessed.
Ignoring these entities does not remove potential registration obligations.
5. Treating a Nil DMTT Liability as an Exemption
An entity expecting no top-up tax liability may still have a registration obligation.
Registration requirements depend on whether the entity falls within the applicable rules, not simply whether tax is payable.
6. Missing the Transitional Relief Election
Under Ministerial Decision No. 120 of 2023, the election to revalue assets at fair market value on the corporate tax effective date must be made in the first corporate tax return.
Missing this opportunity may permanently remove the ability to make the election.
7. Ignoring the 14% Late Payment Rate
Since 14 April 2026, late payment penalties have increased to 14% per annum under Cabinet Decision No. 129 of 2025.
For example, an outstanding tax liability of AED 1 million could result in AED 140,000 in annual interest at that rate.

Frequently Asked Questions
1. What is the UAE corporate tax filing deadline for 2026?
For businesses following a standard January–December financial year, the corporate tax return for the tax period ending 31 December 2025 is due by 30 September 2026.
The return must be filed and any tax payable settled through EmaraTax by this date.
Late filing attracts AED 500 per month for the first 12 months and AED 1,000 per month thereafter. Late payment incurs 14% per annum under Cabinet Decision No. 129 of 2025.
2. Who must register for UAE top-up tax (DMTT) by 30 November 2026?
UAE entities, including free zone companies, branches and permanent establishments, belonging to multinational enterprise groups with consolidated global revenue of EUR 750 million or more in at least two of the four preceding fiscal years.
The 30 November 2026 transitional deadline specifically applies to entities whose first in-scope fiscal year ended before 30 April 2026.
Purely domestic UAE groups are excluded regardless of revenue size.
Registration is through EmaraTax and is separate from corporate tax registration.
3. What happens if I miss the DMTT registration deadline?
The FTA imposes an administrative penalty of AED 10,000 per entity for late registration.
Where a DDFE is responsible for registering multiple entities and misses the deadline, the penalty applies separately to each entity.
4. Is DMTT/top-up tax in addition to the 9% corporate tax?
Yes. DMTT is calculated separately from the standard 9% UAE corporate tax.
It applies when the jurisdictional effective tax rate for the multinational group’s UAE operations falls below 15%.
The top-up tax brings the applicable effective tax rate up to the 15% minimum under the Pillar Two framework.
Groups benefiting from free zone 0% rates or significant exemptions may need to assess their potential top-up tax exposure.
5. When does UAE e-invoicing start?
Phase 1 of mandatory e-invoicing begins in January 2027 for businesses with annual turnover exceeding AED 50 million.
The system follows a DCTCE model with Peppol five-corner architecture, requiring XML/UBL-format invoices, reporting to the FTA, digital signatures and certified Peppol Access Points.
Subsequent phases will extend the requirements to more businesses.
Don’t Let a Missed Deadline Cost Your Business Thousands in Penalties
UAE tax compliance involves more than filing an annual corporate tax return. Businesses must monitor registration, filing, payment, VAT and additional reporting deadlines.
With the 30 November 2026 DMTT registration deadline approaching, qualifying multinational groups should assess their obligations without delay.
