This guide explains the steps for filing the corporate tax return in the UAE for 2025, based on the legal framework stipulated in Federal Decree-Law No. 47 of 2022 on corporate tax, and it sets out the deadlines, required documents, and procedures to be followed to avoid common mistakes.
Filing a corporate tax return in the UAE for the 2025 fiscal year is governed by Federal Decree-Law No. 47 of 2022 on the Taxation of Corporations and Businesses, which applies to all mainland and free-zone companies conducting business in the UAE and requires submission of the return through the Federal Tax Authority (FTA) portal within nine months after the end of the financial year.

WHAT IS THE LEGAL FRAMEWORK THAT GOVERNS CORPORATE TAX RETURNS IN THE UAE?
The UAE corporate tax regime rests on three interlocking instruments:
- Federal Decree-Law No. 47 of 2022 - the Corporate Tax Law, which defines taxable persons, the 0 %/9 % rate structure, exemptions, and the basis for calculating taxable income.
- Cabinet Decision No. 49 of 2023 - provides the detailed criteria for qualifying income in free zones, the substance requirements, and the procedural rules for claiming the 0 % rate.
- Federal Decree-Law No. 28 of 2022 (Tax Procedures Law) - sets out the filing calendar, assessment periods, penalties, interest, and the rights of taxpayers to request extensions or submit amended returns.
Together, these statutes create a coherent system that mirrors international best practices while preserving the UAE's fiscal sovereignty. The Arabic version of each decree, as published in the Official Gazette, is the authoritative text; any English translation is for convenience only.
WHEN MUST A COMPANY FILE ITS CORPORATE TAX RETURN FOR THE 2025 FINANCIAL YEAR?
Under Article 20 of the Corporate Tax Law, a taxpayer has nine months from the close of its financial year to lodge the return.
- Calendar-year entities (financial year ending 31 December 2025) must file by 30 September 2026.
- Non-calendar entities calculate the deadline by adding nine months to their specific year-end date (e.g., a year ending 30 June 2025 → deadline 31 March 2026).
The FTA may grant an extension if the taxpayer demonstrates a genuine impediment (e.g., natural disaster, systemic IT failure). The request must be submitted before the original deadline, and the extension is discretionary-not automatic.
WHAT DOCUMENTS AND INFORMATION ARE REQUIRED TO PREPARE THE CORPORATE TAX RETURN?
A complete filing package consists of the following elements, each of which must be legible, dated, and, where applicable, signed:
| Item | Description | Why it matters |
|---|---|---|
| Audited financial statements | Prepared in accordance with IFRS, signed by an approved auditor. | Forms the starting point for taxable income; the FTA cross-checks these against the tax computation. |
| Tax computation schedule (CT-1) | Shows the reconciliation from accounting profit to taxable income, listing every adjustment (add-backs, deductions, exemptions). | Demonstrates compliance with Articles 22-27 of the Corporate Tax Law. |
| Tax group / participation exemption details | Lists members of a tax group, shareholdings claimed under the participation exemption, and any restructuring relief applied. | Required for claiming exemptions under Articles 23-27. |
| Supporting expense documentation | Contracts, invoices, bank statements, and receipts for all deductible items (e.g., rent, salaries, depreciation). | Enables the FTA to verify that expenses are wholly and exclusively incurred for business purposes. |
| Trade licence & qualifying income declaration | Copy of the mainland or free-zone trade licence; for free-zone entities, the annual qualifying income declaration per Cabinet Decision 49/2023. | Confirms the entity's legal status and eligibility for any 0 % rate benefits. |
| VAT registration certificate (if applicable) | Proof of VAT registration status, needed for reverse-charge considerations. | Ensures consistency between VAT and corporate tax filings. |
The FTA provides an electronic CT-1 template on its e-services portal. Taxpayers must download the template, populate it with the data above, upload the PDF of the audited statements, and attach the supporting schedules as separate files.
HOW IS TAXABLE INCOME CALCULATED UNDER THE UAE CORPORATE TAX LAW?
The calculation follows a two-step process:
- Start with accounting profit (net profit before tax) as shown in the IFRS audited statements.
- Apply statutory adjustments:
- Add-backs (non-deductible items): penalties, fines, bribes, illicit payments, expenses incurred to earn exempt income, and any corporate tax paid in prior periods.
- Deductions (allowable expenses): ordinary business costs (rent, utilities, salaries, professional fees), depreciation/amortisation of assets, genuine bad-debt write-offs, and losses carried forward (subject to the 75 % cap).
- Exemptions: dividends and capital gains qualifying for the participation exemption (minimum 5 % shareholding held >12 months), qualifying free-zone income, and certain foreign-source income exempt under double-tax treaties.
The resulting figure is the taxable income. If it exceeds AED 375,000, the 9 % rate applies to the excess; the first AED 375,000 remains at 0 %.
WHAT ARE THE CORPORATE TAX RATES APPLICABLE FOR THE 2025 FILING YEAR?
| Taxable income bracket | Rate |
|---|---|
| 0 - AED 375,000 | 0 % |
| Above AED 375,000 | 9 % |
Free-zone qualifying income may retain the 0 % rate if the entity satisfies:
- Substance test - adequate physical presence, qualified employees, and operating expenditures in the UAE.
- Activity test - income derived from activities listed in Cabinet Decision 49/2023 (e.g., manufacturing, logistics, certain service sectors).
- Annual declaration - submission of a qualifying income declaration to the FTA each fiscal year.
Failure to meet any of these conditions results in the standard 9 % rate applying to the entirety of the entity's taxable income.
WHAT ARE THE FILING PROCEDURES AND ASSOCIATED COSTS?
The filing workflow is fully digital via the FTA e-services portal:
- Portal registration - If the company is not already registered, create a taxable person profile using the trade licence, Emirates ID of the authorised signatory, and contact details.
- Download CT-1 - Select the appropriate tax period (e.g., FY 2025) and download the pre-filled template.
- Populate the form - Enter revenue, expenses, adjustments, and compute taxable income. The portal validates arithmetic in real time.
- Upload attachments - Attach the audited financial statements (PDF), tax computation schedule, supporting expense documents, trade licence, and qualifying income declaration (if applicable).
- Submit & pay - Review the summary, submit the return, and settle any tax due via the integrated payment gateway (credit card, bank transfer, or e-dirham).
Cost structure:
- Filing fee - None. The FTA does not charge for submitting the CT-1.
- Late-filing penalty - AED 1,000 for each month or part thereof the return is overdue, capped at AED 10,000.
- Interest on unpaid tax - 1 % per month (simple interest) calculated from the day after the deadline until payment is made.
- Additional sanctions - Persistent non-compliance may trigger administrative fines under the Tax Procedures Law (up to 50 % of the tax due) or, in severe cases, criminal prosecution for tax evasion.
WHAT COMMON ERRORS SHOULD COMPANIES AVOID WHEN FILING THEIR CORPORATE TAX RETURN?
Drawing from the firm's experience in contract playbooks (e.g., NA-ESO-011 on tax treatment disclaimers and NA-MSA-030 on taxes), the following pitfalls recur:
| Error | Consequence | Preventive measure |
|---|---|---|
| Misclassifying exempt income as taxable (e.g., treating qualifying free-zone income as taxable) | Overpayment of tax; unnecessary cash outflow | Perform a side-by-side check of income streams against the list in Cabinet Decision 49/2023; retain documentation proving substance and activity compliance. |
| Omitting required add-backs (e.g., forgetting to add back penalties or bribes) | Understatement of taxable income → risk of assessment and penalties | Maintain a master list of non-deductible items per Article 22; run a checklist before finalising the CT-1. |
| Submitting unaudited or draft financial statements | FTA may reject the return or request re-submission, delaying processing | Engage an approved auditor early; obtain the signed audit report before the nine-month window closes. |
| Incorrectly applying the participation exemption threshold (using <5 % shareholding or <12-month holding period) | Loss of exemption, higher tax liability | Keep a shareholder register with acquisition dates; run a quarterly review to confirm eligibility. |
| Missing the nine-month deadline | Automatic AED 1,000-per-month penalty, interest accrual | Set internal calendar reminders six months before year-end; assign a tax compliance officer to monitor progress. |
| Applying the standard 9 % rate to free-zone income without verifying eligibility | Over-taxation; possible refund claims later | Conduct a pre-filing qualifying income assessment; retain the declaration and supporting evidence for audit. |
| Using outdated tax rates or tables (e.g., applying a 0 % rate to all income) | Underpayment, interest, penalties | Subscribe to FTA circulars; update internal tax matrices whenever a new Cabinet Decision is issued. |
Avoiding these errors requires a pre-submission internal audit: reconcile the trial balance to the CT-1, verify each line item against source documents, and have a second reviewer (ideally a tax specialist) sign off.
FREQUENTLY ASKED QUESTIONS
What is the statute of limitation for the FTA to assess corporate tax?
The FTA may issue an assessment within five years from the end of the relevant tax period. If the FTA finds evidence of tax evasion, the period extends to fifteen years under Article 20 of the Corporate Tax Law read together with Article 15 of the Tax Procedures Law.
Can a company file a revised return after discovering an error?
Yes. A taxpayer may submit an amended return within five years of the original filing date, provided the amendment is made voluntarily and before the FTA issues an assessment. This right is enshrined in Article 15 of the Tax Procedures Law.
Are there any specific requirements for free-zone companies regarding qualifying income?
Free-zone entities must:
- Maintain adequate substance (office space, employees, operating expenses) in the UAE.
- Derive income from the activities enumerated in Cabinet Decision 49/2023.
- File an annual qualifying income declaration with the FTA, attaching supporting documentation (e.g., contracts, invoices, payroll records).
Failure to meet any of these conditions results in the loss of the 0 % rate benefit for the relevant fiscal year.
How does the corporate tax law treat losses carried forward?
Tax losses may be carried forward for up to five consecutive tax years. In any given year, the amount of loss that can be offset is limited to 75 % of that year's taxable income (Article 22). Any excess loss continues to be carried forward subject to the same annual cap.
Is there a requirement to appoint a tax agent for filing?
Appointment of a licensed tax agent is not mandatory. Companies with robust internal tax functions may file directly. However, engaging a licensed agent can be advantageous when:
- The entity lacks familiarity with the CT-1 format or the adjustment rules.
- The structure involves complex tax groups, participation exemptions, or cross-border transactions.
- There is a history of prior FTA queries or penalties.
The agent must hold a valid licence from the FTA and act within the scope of their authorization.
What happens if a company fails to file the return by the deadline?
The FTA imposes a late-filing penalty of AED 1,000 per month or part thereof, up to a maximum of AED 10,000. Simultaneously, interest accrues on any unpaid tax at 1 % per month (simple interest). Continued non-compliance may lead to additional fines (up to 50 % of the tax due) under the Tax Procedures Law and, in cases of deliberate evasion, potential criminal proceedings.
