What Is Corporate Tax Filing in the UAE?

Corporate tax filing is an annual legal obligation for every taxable person in the UAE. Under Federal Decree-Law No. 47 of 2022, specifically Articles 48 through 54, all businesses that have registered for corporate tax must submit a tax return to the Federal Tax Authority for each tax period. Filing is not optional; it applies regardless of whether your business owes tax, reports a loss, or elects relief.

This obligation covers a broad range of entities. Mainland companies operating under a commercial licence, Free Zone entities, including those that qualify for the 0% rate as a Qualifying Free Zone Person, and non-residents with a permanent establishment in the UAE are all required to file. Even businesses that elect small business relief corporate tax must submit a return declaring that election.

All corporate tax returns are submitted electronically through the FTA’s EmaraTax portal at tax.gov.ae. There is no paper-based filing option. Through EmaraTax, businesses enter their Tax Registration Number (TRN), select the relevant tax period, report taxable income, declare any elections or exemptions, and upload supporting documentation.

When is Your Corporate Tax Return Due?

The filing deadline is calculated as nine months from the end of your financial year. This means:

  • December financial year-end → Filing deadline: 30 September of the following year.
  • March financial year-end → Filing deadline: 31 December of the same year.
  • June financial year-end → Filing deadline: 31 March of the following year.

There is currently no provision for deadline extensions under the FTA framework, making timely preparation essential.

It is also important to note the 2025 penalty waiver initiative. The FTA announced in April 2025 that businesses filing their first corporate tax return within seven months of their first tax period — rather than the standard nine — can have the AED 10,000 late registration penalty waived. This one-time measure has already benefited over 33,900 taxpayers as of mid-2025. Businesses concerned about potential fines should review the full uae corporate tax penalty schedule to understand their exposure.

Documents & Information Required for Corporate Tax Filing

Before submitting your corporate tax return, you must gather and prepare several key documents. Incomplete or inaccurate submissions can trigger FTA queries, processing delays, or financial penalties.

Tax Registration Number (TRN)

You cannot file a return without a valid Tax Registration Number. If your business has not yet completed UAE corporate tax registration, this must be done first through the EmaraTax portal. Registration is a prerequisite to filing, not a step that can happen concurrently.

Audited Financial Statements

Audited financial statements prepared under IFRS (International Financial Reporting Standards) are required for businesses with annual revenue exceeding AED 50 million. Under Ministerial Decision No. 84 of 2025, audited statements are also mandatory for all Qualifying Free Zone Persons, regardless of their revenue level. Even companies below these thresholds should maintain IFRS-compliant financial records, as the FTA may request them at any time during a compliance review or audit.

Tax Computation Workpaper

This is the core document that connects your accounting profit to your taxable income. Starting from your net accounting profit, you apply every mandatory adjustment required under the CT Law, adding back non-deductible expenses, removing exempt income, and accounting for any transfer pricing adjustments. The final result is the taxable income figure on which your liability is calculated. Businesses that want to verify their figures in advance can use our corporate tax calculation UAE guide for a detailed walkthrough.

Transfer Pricing Documentation

If your business engages in transactions with related parties or connected persons, you must maintain transfer pricing UAE documentation, including a master file and a local file. A transfer pricing disclosure form must also be submitted alongside your annual corporate tax return.

Elections and Declarations

Your tax return must accurately reflect any elections you are making for the relevant tax period. These include electing Small Business Relief, opting into the Qualifying Free Zone Person regime, or forming a Tax Group with related entities.

Supporting Schedules

The FTA may require detailed breakdowns of exempt income, non-deductible expenses, related-party transactions, and any carry-forward losses. Businesses that rely on professional accounting services in Abu Dhabi are typically better equipped to compile these schedules accurately and efficiently, reducing the risk of errors that could trigger penalties or audits.

 

How to File Corporate Tax in the UAE: Step-by-Step

Filing your corporate tax return is more than just logging into the EmaraTax portal; it requires meticulous financial alignment. From preparing your audited statements to the final submission, here is the exact step-by-step process required to ensure your filing is accurate, compliant, and penalty-free.

01

Gather Financial Statements & Records

Begin by compiling your complete financial statements prepared in accordance with IFRS or other FTA-accepted accounting standards. This includes your trial balance, profit and loss statement, balance sheet, and all supporting documentation such as invoices, contracts, and bank statements. If your revenue exceeds AED 50 million or you are a Qualifying Free Zone Person, these financial statements must be audited by an independent auditor. Ensuring your records are accurate and fully reconciled is the foundation of a compliant corporate tax return.
02

Prepare Tax Computation

Using your accounting profit as the starting point, apply all mandatory adjustments required under the UAE Corporate Tax Law. This involves adding back non-deductible expenses, such as certain regulatory fines and entertainment costs exceeding FTA limits, removing exempt income including qualifying dividends and capital gains, and making any required transfer pricing UAE adjustments for related-party transactions. Factor in any elections you are claiming, such as Small Business Relief or QFZP status. The result of this process is your taxable income, to which the UAE’s 0% and 9% rate bands will apply.
03

Complete FTA Return Form

Log in to the EmaraTax portal using your UAE Pass credentials. Select the relevant tax period and enter your Tax Registration Number, your computed taxable income figure, any elections made during the period, and the total tax payable. If applicable, ensure your UAE corporate tax registration details are current and accurate. Every figure entered on the return must match your tax computation workpaper exactly, as discrepancies between the return and your supporting documents can trigger an FTA review.
04

Submit via EmaraTax

Upload your completed return form along with all supporting schedules, including your tax computation workpaper, financial statements, and transfer pricing disclosure form if applicable. Review the submission summary carefully, then submit the return electronically. Retain the confirmation receipt generated by EmaraTax as your proof of timely filing. This receipt is critical evidence in the event of any future FTA inquiry.
05

Pay Tax Liability & Retain Records

Settle your corporate tax via EmaraTax by the deadline to prevent a 14% annual late payment interest. Post-payment, you must legally retain all financial and tax records for seven years. Failing to maintain these documents triggers standalone FTA penalties of up to AED 20,000. Our experts in tax and accounting services in Abu Dhabi ensure your records remain flawlessly organized and audit-ready throughout the entire retention period.
