UAE Corporate Tax Deadlines 2026: Filing, Registration & the 9% Rate

1. Who needs to register for Corporate Tax?

UAE taxable persons generally need to register with the Federal Tax Authority (FTA) and obtain a Corporate Tax Registration Number. Some exempt persons can also be required to register; a branch of a UAE company is generally part of the parent rather than a separate registrant. Check the entity's category and FTA registration deadline before filing.

Late registration can attract an AED 10,000 administrative penalty. The FTA also provides a conditional waiver for qualifying first tax periods when the first return or annual declaration is filed within seven months of that period's end. Review the current FTA waiver guidance before assuming a penalty is unavoidable.

2. The 9% Statutory Tax Rate & AED 375,000 Threshold

The UAE Corporate Tax structure follows a progressive tiered framework designed to nurture enterprise development:

• 0% Rate: Applies to the portion of taxable income that does not exceed AED 375,000 during the relevant tax period.

• 9% Standard Rate: Applies to all taxable income exceeding AED 375,000.

Taxable income generally starts with the accounting result and is adjusted under Corporate Tax rules. Audited financial statements are required in some cases, including for a Qualifying Free Zone Person, but should not be described as mandatory for every taxpayer.

3. Filing Windows: The Strict 9-Month Post-Year-End Deadline

The FTA generally requires a Corporate Tax return and payment within nine months after the end of the taxable person's tax period. For a tax period ending 31 December 2025, the FTA confirmed a 30 September 2026 deadline. Different year-ends produce different dates.

Prepare the trial balance, financial statements, reconciliations and evidence for adjustments or reliefs early enough for review. The seven-month condition for a first-period late-registration penalty waiver is separate from the usual nine-month return deadline.

4. Official FTA guidance to check before filing

Use the FTA Corporate Tax Returns guide for filing requirements and EmaraTax steps, and the FTA's current penalty-waiver page when assessing a late registration case. TaxBay can help review the records and prepare the return, but eligibility and deadlines depend on the entity's facts.
