Corporate Tax Filing UAE: How to Avoid Penalties Before the 30 September 2025 Deadline

The implementation of corporate tax in the UAE places emphasis on compliance, reporting, and transparency. Under the current regime, a key deadline is 30 September 2025, marking the corporate tax filing due date for entities with an accounting period ending on 31 December 2024. Failure to comply may result in penalties, financial strain, and complications with the Federal Tax Authority (FTA). Accordingly, all businesses, whether small enterprises, free zone entities, or large corporations, must understand the requirements, necessary documentation, and preparation steps for corporate tax return filing in the UAE.

Importance of the 30 September 2025 Deadline

For businesses with a financial year ending on 31 December 2024, the corporate tax filing deadline in the UAE is 30 September 2025.

Timely and proper filing ensures:

• Avoidance of UAE corporate tax penalties.
• Smooth business operations without last-minute compliance pressure.
• Clean financial records to enable audits or review of taxes.
• Good standing with investors and regulators.

Penalties for Missing the Corporate Tax Deadline

The FTA has stipulated strict terms of non-compliance. Businesses delaying corporate tax filing UAE may face penalties as follows:

• AED 500 per month (maximum 12 months) for late submission of tax returns.

• AED 10,000 penalty for late corporate tax registration.

• Additional penalties for errors, misdeclarations, or incomplete submissions.

What Businesses Must Do Before Filing

To meet the corporate tax filing deadline UAE on time, businesses are advised to ensure the following:

1. Prepare financial statements - Ensure your accounts are properly maintained, preferably audited, in readiness for your filing.
2. Calculate taxable income – Dealing with exempt income, reliefs, and deductible allowances under the UAE Corporate Tax Law.
3. Determine tax liability – Businesses pay 0% on taxable income up to AED 375,000, and 9% on income above that threshold.
4. File online using EmaraTax – Submit your tax return on the government's FTA portal.
5. Pay on time – Payment of any delayed tax on the due date of the company tax avoids extra charges.

• Submission of incomplete or incorrect documents.
