Overview
- The 30th September corporate tax deadline is approaching, but businesses still have time to ensure compliance.
- The deadline is generally nine months after the end of the tax period—30th September applies to businesses with a 31st December year-end.
- For a 31st December 2025 year-end, both the tax return and any tax payable are due by 30th September 2026.
- Late filing, late payment, and late registration can each result in separate penalties, with late registration carrying an AED 10,000 penalty.
30th September: UAE Corporate Tax Deadline
Under the UAE Corporate Tax Law, every taxable person must file their return and settle any tax due within nine months from the end of their relevant tax period. Thus, UAE businesses must plan around this date, which is relevant to their financial year-end.
However, as most businesses in the UAE follow the Gregorian calendar year-end, i.e., 31st December, as their financial year-end, the filing deadline for them is 30th September of the following year. Thus, understand the rule: the deadline is the formula, not the fixed date. For instance, if an entity has a year ending on 31st January 2026, the deadline will be 31st October 2026.
Things to Do Before the Corporate Tax Deadline
Depending on the relevant circumstances, your business might not have 30th September as the corporate tax filing deadline. However, irrespective of the date, tasks you must finish before the deadline remain the same. Let’s highlight some of the key areas to review before the deadline.
- Complete bookkeeping for the relevant period
- Reconciliation of bank accounts and other key accounts
- Financial statements as per IFRS
- Reviewing deductible and non-deductible expenses
- Calculating taxable income
- Reviewing applicability of tax incentives
- Reviewing related party transactions and related documentation
- Compiling all the relevant records and documentation
- Calculating the correct tax liability and submission through the EmaraTax portal.
These are general tasks that apply to most of the businesses; however, depending on the nature of the business and other circumstances, there can be additional tasks and documentation.
Getting Ahead of Your Deadline: Don’t Wait until 30th September
Deadlines are not meant to delay the tasks until the last day; delaying creates panic and a higher risk of errors and penalties. Therefore, a safe approach is to maintain a culture within the organization where there are internal deadlines totally aligned with the statutory deadlines. For instance, if your corporate tax deadline is 30th September, it is better to finish internal tasks way earlier than this due date to keep a buffer.
A great way is to hand over the compliance burden to an expert, such as CZTA. In this way, your business will never face an avoidable penalty.
Penalties for Missing the Deadline
The UAE is a business-friendly jurisdiction; however, there is no compromise on non-compliance. Concerning the filing deadline, there can be certain penalties depending on the specific circumstances of a business. The penalties range from monthly penalties for non-filing to variable penalties on unpaid tax liabilities. The following penalties can apply:
- AED 500 per month for the first 12 months of delay, rising to AED 1,000 per month from the 13th month onwards.
- A percentage-based monthly penalty on the unpaid tax amount, applied from the day after the due date until settlement.
- AED 10,000 for businesses that failed to register for corporate tax within the stipulated timeframe. However, this can potentially be waived under an FTA initiative if the first return is filed within seven months of the first tax period end. For further information, read Penalty Waiver for Late Corporate Tax Registration.
It is worth noting that filing and settling the tax liability are separate obligations. However, they both have the same deadline.
