Corporate Tax Return Filing Deadline in UAE: Everything Businesses Should Know

Taxable businesses must submit their annual corporate tax return and pay any tax due within nine months of their financial year-end under Federal Decree-Law No. 47 of 2022. Missing this deadline can lead to administrative penalties, FTA queries, and pressure on year-end closing, especially for groups with multiple UAE entities and free zone companies.

The Federal Tax Authority has clarified that a business with a 31 December 2025 year-end must file and pay by 30 September 2026 through EmaraTax. We explain who must file, how the nine-month rule applies, the 2026 example date, and the key documents required so you can plan corporate tax compliance with confidence.

Key Takeaways

• A UAE corporate tax return is an electronic declaration to the Federal Tax Authority of income, expenses, and the resulting tax liability for each tax period.
• Taxable persons, including UAE juridical persons, free zone companies, and certain foreign entities with a UAE nexus, must file returns once registered for corporate tax.
• Under Federal Decree-Law No. 47 of 2022, corporate tax returns and payments are generally due within nine months after the end of the financial year.
• For entities with a 31 December 2025 year-end, the confirmed corporate tax filing and payment deadline is 30 September 2026 under Decision No. 7 of 2024.
• Accurate filing requires organised financial statements, general ledger, bank statements, invoices, and contracts to support the taxable income calculation reported through EmaraTax.
• Separating registration from filing is essential, as holding a Tax Registration Number creates a recurring duty to submit annual corporate tax returns, even at a 0% rate.
  
  

What is a Corporate Tax Return?

A corporate tax return in the UAE is the formal declaration of a taxable person’s income, expenses, adjustments, and resulting tax liability for a specific tax period under Federal Decree-Law No. 47 of 2022. The return is filed with the Federal Tax Authority through EmaraTax, using the prescribed electronic form for each tax period.

The return summarises the financial performance of the business and translates it into taxable income based on the conditions in the Law. Corporate tax registration creates the legal obligation to file, but it is not the filing itself. When a business completes corporate tax registration and receives its Tax Registration Number, it must submit a separate annual return for each tax period.

We ensure clients understand this distinction, maintain compliant records, and complete accurate returns through EmaraTax in line with FTA guidance such as the Corporate Tax Returns Guide CTGTXR1.

Who Must File?

Under Federal Decree-Law No. 47 of 2022, the obligation to file a corporate tax return applies to taxable persons, not to every entity in the UAE. A taxable person can be a juridical person, a natural person carrying on a business, or a non-resident with a permanent establishment or nexus in the UAE.

Once registered and issued with a Tax Registration Number, these persons must file for every tax period, even if the calculated tax is zero. The filing population includes mainland entities, free zone companies, and certain foreign or individual businesses that meet the tests in the Law. We assess group structures, contracts, and Tax Residency Certificate positions to determine who must file and when registration is required.

Eligible businesses and taxable persons

The Law sets out who qualifies as a taxable person, which then links directly to the filing obligation. Understanding these categories helps groups identify all legal entities that may require registration and annual returns, including special cases involving free zones and foreign structures.

• Juridical persons incorporated in the UAE: Companies and other legal persons formed under UAE law generally fall within the corporate tax net and must file returns.
• Free zone companies: Free zone entities, including potential qualifying free zone persons, are taxable persons that must register and file, even where a 0% rate may apply.
• Foreign entities with a UAE nexus: Non-resident companies with a permanent establishment or state-sourced income with a UAE nexus must register and file on their UAE taxable income.

Registration vs. filing

Registration for corporate tax is the first compliance step and results in a Tax Registration Number issued by the Federal Tax Authority. Filing is a separate, recurring obligation: a business must submit its completed Corporate Tax Return for each tax period within the prescribed deadline, regardless of whether it has tax to pay.

Corporate Tax Filing Deadline

For each tax period, Federal Decree-Law No. 47 of 2022 requires taxable persons to file a corporate tax return and settle the tax due within a specific timeframe. The standard rule is that both the filing and payment deadlines fall within nine months after the end of the relevant financial year or tax period.

The Federal Tax Authority has confirmed through guidance and decisions that returns are filed electronically through EmaraTax. This nine-month corporate tax filing deadline applies to all taxable persons unless a specific FTA decision sets a different timeline.

For a business with a financial year ending on 31 December 2025, the filing and payment deadline is 30 September 2026, as clarified by Decision No. 7 of 2024. We support businesses in planning their corporate tax filing schedule, integrating the deadline with financial close, audit processes, and corporate tax registration status so required information is ready well before the due date.

9-month filing rule

The nine-month deadline is central to corporate tax compliance in the UAE because it ties together both the reporting and payment obligations. Missing this window can lead to administrative penalties under FTA decisions and increase the risk of follow-up queries or assessments.

• Due within 9 months after the tax period ends: The corporate tax return must be filed no later than nine months after the end of each financial year.
• Applies to return filing and tax payment: The same nine-month deadline applies both to submitting the return and paying the corporate tax liability shown in it.
• Filed electronically: Taxable persons submit their returns through the FTA’s EmaraTax portal, using the dedicated corporate tax return form for each period.

Filing deadline table

Many UAE businesses use non-calendar financial years for group alignment, which affects their exact corporate tax filing deadline. Mapping the nine-month rule to specific year-end dates helps management lock in internal timetables for closing the accounts, approving financial statements, and preparing the return.
