Corporate Tax Filing in UAE: Your Essential 2026 Compliance Guide

Introduction
As we close 2025 and enter 2026, corporate tax filing remains a critical responsibility for businesses operating in the UAE. The Federal Tax Authority (FTA) continues to enforce strict compliance measures, making it essential for companies to understand their corporate tax filing obligations to avoid penalties and maintain smooth operations.

The UAE Corporate Tax Law came into effect on June 1, 2023, with a standard rate of 9% on taxable profits exceeding AED 375,000. Businesses earning below this threshold enjoy a 0% rate. Additionally, from January 1, 2025, a 15% Domestic Minimum Top-Up Tax (DMTT) applies to large multinational enterprises with consolidated global revenues exceeding EUR 750 million, aligning with OECD global minimum tax standards.

What is Corporate Tax Filing in UAE?
Corporate tax filing in the United Arab Emirates is the process of submitting a comprehensive report to the Federal Tax Authority detailing your company's income, expenses, and tax liability for a specific tax period. The Corporate Tax Return must be filed within nine months after the end of your financial year through the EmaraTax digital platform.

Every taxable person must register for Corporate Tax and obtain a Tax Registration Number. The FTA may also require exempt persons to register in certain cases, making it crucial to understand your registration obligations.

Is it Mandatory To File Corporate Tax Returns in UAE?
Yes, corporate tax filing is mandatory for all companies operating in the UAE, regardless of size or profitability. The Federal Tax Authority requires businesses to file tax returns and pay taxes on their taxable income according to UAE tax laws.

Failure to comply with corporate tax filing obligations results in significant penalties including AED 10,000 for late registration, AED 500-1,000 for late filing, and 14% per annum interest on late payments. These penalties apply to both UAE-based and foreign companies with operations in the country.

Should UAE Businesses With No Income File CT Returns?
All taxpayers are required to file a Corporate Tax return, irrespective of income level or company status. Even if your business generated no taxable income, you must submit a nil return to maintain compliance with FTA requirements.

Should Free Zone Entities File for Corporate Tax Returns?
Corporate Tax applies to Free Zone Persons as well. All Free Zone entities must file Corporate Tax returns, whether they qualify as Qualifying Free Zone Persons (QFZP) or not. QFZPs can benefit from a 0% tax rate on qualifying income, but filing remains mandatory regardless of tax liability.

How Often Should Businesses File for Corporate Tax Returns in UAE?
UAE businesses file corporate tax returns once per tax period—nine months after the tax period ends. No advance or preliminary corporate tax filings are necessary, simplifying the compliance process.

What is the Deadline For Corporate Tax Filing in UAE?
Businesses have up to 9 months from the end of their relevant tax period to submit their corporate tax return and pay any Corporate Tax due to the Federal Tax Authority. 
Key deadlines for 2026:
● Calendar year businesses (Jan 1-Dec 31, 2025): September 30, 2026
● Fiscal year businesses (Apr 1, 2025-Mar 31, 2026): December 31, 2026
● Businesses with year-end June 30, 2025: March 31, 2026
This extended timeline reflects the UAE's commitment to ensuring smooth implementation while giving businesses adequate preparation time.

Major 2025 Updates Affecting Your 2026 Filing?
Domestic Minimum Top-Up Tax (DMTT)
For financial years starting on or after January 1, 2025, the UAE introduced a 15% Domestic Minimum Top-Up Tax targeting multinational enterprises with consolidated global revenues of EUR 750 million or more. If your MNE's effective tax rate in the UAE falls below 15%, the top-up tax applies. 
Enhanced Transfer Pricing Requirements
MNE groups with consolidated global revenues exceeding AED 3.15 billion must submit Master File and Local File documentation following OECD guidelines. UAE companies with local revenue over AED 200 million must also comply with these enhanced documentation requirements.
Natural Persons Registration
Freelancers, sole proprietors, and individuals earning over AED 1 million annually from business activities must register for corporate tax by March 31, 2025, or face an AED 10,000 penalty.
