The UAE corporate tax deadline of 30 September 2026 is now less than 30 days away. If your business has a financial year ending 31 December 2025, this is the date by which you must file your corporate tax return and settle any tax due through the FTA’s EmaraTax portal. Missing it means automatic penalties starting at AED 500 per month, with no extensions granted.
The Federal Tax Authority has issued a reminder urging all taxable persons to prepare early, gather their documentation, and submit well ahead of the deadline. Whether you are filing for the first time or have been through the process before, understanding the key deadlines and compliance requirements is essential.
What Is the UAE Corporate Tax Deadline?
Under Federal Decree-Law No. 47 of 2022, every business subject to UAE corporate tax must file its tax return within nine months of the end of its financial year. Both the submission of the return and payment of any tax liability must be completed by the same deadline.
The corporate tax regime applies to:
- Juridical persons incorporated or managed in the UAE
- Natural persons with annual turnover exceeding AED 1,000,000
- Non-residents with a permanent establishment or nexus in the UAE
The standard tax rates are:
- 0% on taxable income up to AED 375,000
- 9% on taxable income exceeding AED 375,000
Who Must File?
The 30 September 2026 deadline applies specifically to businesses whose tax period ended on 31 December 2025, including:
Mainland Companies
Mainland companies with a December 31 year-end must file by 30 September 2026.
Free Zone Entities
Free zone businesses must file even if they qualify for the 0% Qualifying Free Zone Person (QFZP) regime.
Sole Establishments and Freelancers
Individuals conducting business activities with annual turnover exceeding AED 1,000,000 are subject to corporate tax filing requirements.
Foreign Branches
UAE branches of foreign companies that constitute a permanent establishment must submit a corporate tax return.
Small Business Relief Applicants
Businesses with revenue up to AED 3,000,000 claiming Small Business Relief must still submit a corporate tax return and elect the relief through EmaraTax.

Important Note for First-Time Filers
Businesses filing their first corporate tax return within seven months of the end of their tax period may qualify for a waiver of the AED 10,000 late registration penalty. Businesses with a December 2025 year-end had until 31 July 2026 to benefit from this waiver.
Key Requirements Before Filing
Tax Registration
A valid Tax Registration Number (TRN) is required before filing. Late registration may result in a penalty of AED 10,000.
Financial Statements
Returns must be prepared based on audited or certified financial statements prepared under IFRS or IFRS for SMEs.
Tax Adjustments
Businesses must adjust accounting profits for non-deductible expenses, including:
- Government fines and penalties
- Personal expenses
- Excess entertainment expenses
- Non-qualifying donations
Transfer Pricing Compliance
Businesses with related-party transactions must comply with UAE transfer pricing regulations and maintain supporting documentation where required.
Transitional Relief
First-time filers may have an opportunity to elect transitional relief under Article 61 of the Corporate Tax Law. Missing this election in the first return may result in the loss of the benefit permanently.

Common Mistakes to Avoid
Assuming No Profit Means No Filing
A return is required even if your business made no profit or qualifies for relief.
Poor Bookkeeping
Incomplete records can lead to filing errors and increased scrutiny from the FTA.
Incorrect Classification of Income and Expenses
Businesses should carefully distinguish between taxable income, exempt income, capital expenditure, and deductible expenses.
Ignoring Related-Party Transactions
Related-party transactions must be disclosed and supported by arm’s-length pricing documentation.
Missing Transitional Relief Elections
First-time filers should carefully assess whether transitional relief elections are beneficial.
Waiting Until the Last Minute
Technical issues, payment delays, or missing documents can prevent timely filing.
