How to File Your UAE Corporate Tax Return Before the 30 September 2026 Deadline

Meta description: Learn how to file your corporate tax UAE return by 30 September 2026, prepare documents, claim reliefs, and avoid automatic FTA penalties.

For UAE businesses with a financial year ending on 31 December 2025, the deadline to file the corporate tax return and pay any tax due is 30 September 2026.

This deadline applies to calendar-year taxpayers and is based on the requirement to submit a corporate tax return within nine months of the end of the relevant financial year. The Federal Tax Authority (FTA) has reminded eligible businesses, including those considering Small Business Relief, that filing remains mandatory.

There are no routine extensions for this deadline. Missing it can trigger automatic penalties even where the business has no corporate tax payable. With the deadline approaching, we recommend completing your registration, accounting review, tax computation, and EmaraTax submission as early as possible.

How to Confirm Whether the 30 September Deadline Applies

The first step is to confirm your company’s financial year and tax period.

The 30 September 2026 deadline generally applies when:

• Your financial year ran from 1 January 2025 to 31 December 2025.
• Your business is a taxable person required to submit a UAE corporate tax return.
• Your company is registered, or should be registered, for Corporate Tax with the FTA.
• Your business has not already completed its return and payment obligation for that period.

Under the UAE Corporate Tax framework, the return and any corporate tax due must normally be submitted and paid within nine months from the end of the financial year. Businesses with a different year-end will have a different filing date.

For example, a business whose financial year ends on 31 March 2026 would generally have a deadline nine months after that year-end. Therefore, businesses should not assume that 30 September applies to every UAE entity.

The FTA’s official guidance confirms that taxpayers with a 31 December 2025 year-end must submit their corporate tax returns and settle any tax due by 30 September 2026. Businesses can review the FTA Corporate Tax resources and access services through EmaraTax.

How to Prepare Your Corporate Tax Filing Checklist

Successful filing begins with preparation. In our experience, delays commonly occur because financial records are incomplete, EmaraTax access is unavailable, or the company has not reconciled its accounting profit with its taxable income.

Use the following checklist before beginning the return:

• Confirm Corporate Tax registration with the FTA.
• Verify your Tax Registration Number (TRN).
• Confirm that authorised users can access EmaraTax.
• Finalise financial statements for 1 January–31 December 2025.
• Reconcile bank statements, sales records, expenses, receivables, and liabilities.
• Review fixed assets, acquisitions, disposals, and ownership records.
• Calculate accounting profit or loss.
• Prepare the UAE Corporate Tax computation.
• Identify exempt income and non-deductible expenses.
• Assess available reliefs, elections, or special regimes.
• Review whether Small Business Relief may apply.
• Confirm the amount of Corporate Tax payable, if any.
• Keep supporting records and evidence for future FTA queries.

The FTA has stated that businesses must maintain records supporting revenue, taxable income, assets, liabilities, transactions, and ownership interests. The specific records required may vary depending on the business activity and structure.

How to Calculate Taxable Income Correctly

Corporate Tax is generally calculated using taxable income rather than simply applying a rate to gross revenue.

The process usually begins with the company’s accounting profit or loss for the relevant period. We then review the accounts and identify adjustments required under UAE Corporate Tax rules. These may include:

• Income that is exempt from Corporate Tax.
• Expenses that are not deductible or are subject to specific limitations.
• Allowable business expenses incurred for generating taxable income.
• Related-party transactions requiring additional review.
• Tax losses that may be available for carry-forward, where applicable.
• Qualifying income or other conditions relevant to a free zone business.
• Elections and reliefs available to the company.

The standard UAE Corporate Tax rate is generally 0% on taxable income up to AED 375,000 and 9% on taxable income exceeding AED 375,000, subject to the applicable legislation and the business’s circumstances.

Revenue is not the same as taxable income. A company may have significant revenue but relatively low taxable profit after allowable costs. Conversely, inaccurate expense classifications can result in an incorrect return and unnecessary tax exposure.

We recommend preparing a written computation that explains how the figures in the return were derived from the financial statements. This creates a clear audit trail and supports a more efficient response if the FTA requests clarification.

How to Assess Small Business Relief Before Filing

Small Business Relief may be relevant to eligible UAE resident businesses. The FTA has confirmed that eligible businesses must still register, maintain supporting records, and submit a simplified corporate tax return within the legal deadline.

Where the conditions are satisfied, a resident person with revenue not exceeding AED 3 million for the relevant tax period and applicable previous periods may be able to elect for Small Business Relief. The relief is not automatic. The business must make the appropriate election through its Corporate Tax return and retain evidence supporting its eligibility.

Important points include:

• Small Business Relief does not remove the filing obligation.
• The revenue threshold and other eligibility conditions must be reviewed carefully.
• The business must retain records demonstrating its revenue position.
• The relief may not be available to every entity or business structure.
• The return must still be submitted by 30 September 2026 where the deadline applies.

A business should not select the relief simply because its tax payable appears to be zero. We assess the entity’s status, revenue history, ownership, activities, and relevant exclusions before recommending an election.

How to Submit Your Return Through EmaraTax

Once your records and computation are complete, the filing process can be completed electronically through EmaraTax.

Follow these practical steps:

1. Log in to the company’s EmaraTax account.
2. Open the Corporate Tax section.
3. Select the tax period ending on 31 December 2025.
4. Enter the company’s financial and tax information.
5. Report revenue, expenses, accounting profit, and taxable income.
6. Include any reliefs, elections, exemptions, or relevant disclosures.
7. Review the calculated Corporate Tax amount.
8. Validate the return for errors or missing information.
9. Submit the return electronically.
10. Pay any tax due through the available payment channels.
11. Save the submission acknowledgement, reference number, and payment receipt.

Supporting documents may not need to be uploaded with every return. However, businesses should have the relevant records ready if the FTA requests them. This may include invoices, contracts, bank statements, ledgers, payroll records, asset schedules, and tax computations.

Filing and payment should not be left until the final day. Technical access issues, missing approvals, payment processing delays, or an unexpected correction can prevent timely completion.

How to Avoid Automatic FTA Penalties

Missing the 30 September 2026 deadline triggers automatic consequences. This can happen even where the company has no Corporate Tax payable or intends to claim Small Business Relief.

The late filing penalty is:

• AED 500 per month, or part of a month, for the first 12 months after the deadline.
• AED 1,000 per month from the 13th month onward while the return remains outstanding.

This means that filing even one day after the deadline may result in the first monthly penalty being applied. The penalty continues until the return is submitted.

A separate cost may apply where tax remains unpaid. Late payment interest is 14% per annum on unpaid Corporate Tax, calculated in accordance with the applicable FTA rules and continuing until the outstanding amount is settled.

The safest approach is to treat the deadline as fixed and submit before 30 September. If you have already missed a registration or filing obligation, prompt professional review may help identify the correct corrective action. A penalty waiver is not guaranteed, and businesses should not assume that a waiver application suspends the obligation to file or pay.

How to Coordinate Corporate Tax and VAT Compliance

Corporate Tax and VAT are separate obligations, but the records supporting each filing should be consistent.

Businesses registered for VAT should compare their Corporate Tax records with VAT returns, sales ledgers, purchase records, and bank activity. This is particularly important for businesses that complete VAT filing in Dubai or elsewhere in the UAE through different systems or advisers.

Variances can occur because:

• VAT is based on taxable supplies and VAT treatment, while Corporate Tax is based on taxable income.
• Some expenses include recoverable or non-recoverable input VAT.
• Revenue may be recorded on different dates for accounting and VAT purposes.
• Exempt, zero-rated, and out-of-scope transactions may be treated differently.
• Bank receipts may include loans, shareholder funding, deposits, or non-revenue items.

Our VAT and Corporate Tax compliance service helps businesses coordinate registration, return preparation, tax computations, record reviews, and FTA correspondence. Consistent records support compliance and reduce the risk of avoidable queries.
