Key Corporate Tax Deadlines Every UAE Business Must Know
With the establishment of the UAE Corporate Tax (CT) regime, the concept of “deadlines” has taken on a new and critical significance for every business operating in the country. This is no longer a landscape where timelines are flexible; the Federal Tax Authority (FTA) has implemented a structured system with firm, non-negotiable dates for registration, filing, and payment. Missing these deadlines is not an option—it directly results in financial penalties, creates a negative compliance history, and invites unwanted scrutiny from the authorities.

It requires a clear understanding of your company’s financial year, a proactive approach to bookkeeping and financial reporting, and a strategic plan to manage the entire compliance lifecycle. This guide is designed to be your definitive resource for navigating the UAE’s Corporate Tax timeline. We will demystify how to determine your first tax period and break down the crucial deadlines every business must circle on its calendar to ensure seamless compliance and avoid costly mistakes.
Key Takeaways for UAE Corporate Tax Deadlines
- Your Financial Year is Key: All your Corporate Tax deadlines are determined by the start and end dates of your company’s financial year.
- Registration is Urgent: Tax registration deadlines are based on your business’s incorporation date and when you received your license, with staggered timelines set by the FTA. Missing this first step is a critical error.
- The 9-Month Rule: The deadline for both filing your tax return and paying your tax liability is 9 months after the end of your relevant tax period.
- No Distinction in Payment/Filing Date: Unlike some other tax systems, the deadline to file and the deadline to pay are the same.
- Proactive Planning is Essential: Waiting until the eighth month to start preparing is a recipe for disaster. A structured internal timeline is necessary for a smooth process.
Part 1: The Starting Point – Determining Your First Tax Period
Before you can identify any deadline, you must first establish your company’s “first tax period.” This is the first financial period for which you are required to file a Corporate Tax return. The rule is straightforward:
Your first tax period is the first full financial year that starts on or after 1 June 2023.
This means the determining factor is your company’s established financial year. Let’s look at some common examples to illustrate this critical concept.
| If Your Financial Year is… | Your First Tax Period Subject to 9% CT is… | Your Filing & Payment Deadline is… | 
|---|---|---|
| 1 Jan – 31 Dec (Calendar Year) | 1 Jan 2024 to 31 Dec 2024 | 30 September 2025 | 
| 1 April – 31 March | 1 April 2024 to 31 March 2025 | 31 December 2025 | 
| 1 July – 30 June | 1 July 2023 to 30 June 2024 | 31 March 2025 | 
As the table shows, a business with a July-June financial year is among the first to file, with a deadline in early 2025. Conversely, a business following the calendar year has until Q3 2025. It is absolutely crucial to confirm your company’s financial year and identify your first tax period, as this date is the anchor for all subsequent deadlines.
Part 2: The Core Deadlines – A Detailed Breakdown
Once you know your tax period, you can map out the key compliance deadlines. These are not suggestions; they are legal obligations.
1. Tax Registration Deadline
This is the very first deadline every business must meet. The FTA has issued specific deadlines for Corporate Tax registration based on the month a business’s license was issued, regardless of the year of issuance. There is a separate timeline for businesses incorporated after 1 March 2024. Failure to register on time leads to penalties. For example, a company with a license issued in January or February (any year) had a deadline of 31 May 2024. It is imperative to check the FTA’s official schedule and ensure your business is registered well before your deadline. This is a foundational step for all company formation and operation activities.
2. Tax Return Filing Deadline
The deadline to submit your annual Corporate Tax return to the FTA is **within 9 months from the end of your tax period**.
- For a company with a tax period ending 31 December 2024, the filing deadline is 30 September 2025.
- For a company with a tax period ending 30 June 2024, the filing deadline is 31 March 2025.
This requires having your financial statements finalized and audited (if applicable) well in advance. Meticulous accounting and bookkeeping throughout the year is essential to meet this deadline without a last-minute rush.
3. Tax Payment Deadline
The deadline to pay your Corporate Tax liability is the **same as the filing deadline: within 9 months from the end of your tax period**. There is no extension for payment. You must ensure you have the necessary funds available to settle your tax bill by this date. Effective accounts payable and receivable management is key to ensuring healthy cash flow for tax payments.
4. Transfer Pricing Documentation Deadlines
If your business engages in transactions with Related Parties or Connected Persons, it is subject to Transfer Pricing rules. While the detailed Transfer Pricing Disclosure Form must be submitted with your tax return, you are also required to have your Master File and Local File documentation completed and ready **by the tax return filing deadline**. The FTA can request this documentation at any time, and you must be able to provide it. This is a complex area where strategic CFO services are invaluable.
Part 3: Building a Proactive Compliance Calendar
Simply knowing the final deadline is not enough. A proactive approach involves creating an internal calendar with key milestones to ensure a smooth, stress-free process.
Waiting until month seven or eight of your nine-month window is a common mistake that leads to errors, oversights, and immense pressure on your finance team.
A Sample Internal Compliance Timeline (for a 31 Dec Year-End):
- January 2025 (Month 1): Close the 2024 financial books. Begin the process of account reconciliation.
- February-March 2025 (Months 2-3): Prepare draft financial statements. Engage auditors for the annual external audit.
- April-May 2025 (Months 4-5): Finalize audited financial statements. Begin detailed Corporate Tax calculations and tax provision work.
- June 2025 (Month 6): Prepare the first draft of the Corporate Tax return and supporting schedules.
- July 2025 (Month 7): Conduct an internal review of the tax return. A professional accounting review can identify potential issues.
- August 2025 (Month 8): Finalize the tax return and obtain necessary approvals from management.
- September 2025 (Month 9): File the Corporate Tax return and process the tax payment well before the 30 September deadline.
This structured approach transforms tax compliance from a single, high-stakes event into a manageable, year-round process.
