How to File Your UAE Corporate Tax Return on EmaraTax — 2026 Cycle 2

If your UAE company's financial year ended on 31 December 2025, your UAE corporate tax return and any tax due must be settled by 30 September 2026. This corporate tax deadline UAE 2026 is a firm cutoff. EmaraTax will not grant an automatic extension, and missing it starts the penalty clock immediately. This guide walks you through exactly how to handle your EmaraTax portal filing, from gathering documents to final submission.

Key Takeaways

• Who must file? Every registered taxable person, including mainland LLCs, free zone entities, and foreign companies with a UAE permanent establishment, must file, even when tax owed is zero.
• What is the 2026 deadline? For a 31st December 2025 financial year-end, the filing and payment deadline is 30th September 2026.
• Where do you file? Exclusively through the EmaraTax portal at eservices.tax.gov.ae.
• What are the rates? 0% on taxable income up to AED 375,000; 9% on the amount above it.
• Does the payment have a separate deadline? No. Payment is due on the exact same date as the return, there is no separate payment window.

Who Must File and By When

UAE Corporate Tax law requires every registered taxable person to file an annual return within 9 months of the end of their tax period. The key dates for 2026 look like this:

• Financial Year-End | Filing & Payment Deadline
• 31 December 2025 | 30 September 2026
• 31 March 2026 | 31 December 2026
• 30 June 2026 | 31 March 2027
• 30 September 2026 | 30 June 2027

Because most UAE businesses run a calendar year, 30 September 2026 applies to the majority, and for them, this is their second corporate tax return.

The filing obligation is broad. It covers:

• UAE mainland companies such as LLCs, sole establishments, civil companies, and branches.
• Free zone entities, including those that expect to report a 0% outcome under QFZP rules.
• Foreign companies with a UAE permanent establishment.

Government entities, qualifying public benefit entities, and pension funds that hold formal exemptions are generally outside scope. If you are unsure whether your entity has to file, check your registration status on EmaraTax or speak to a tax advisor before the deadline approaches.

What to Gather Before You Start

Filing on EmaraTax is a self-assessment process, so the numbers you enter must tie directly to your books and supporting documentation. Attempting the return with incomplete records is the single most common reason businesses make errors on the form.

Before you log in, make sure you have:

• Corporate Tax TRN: Your tax registration number issued by the FTA. This is separate from your VAT TRN if you are also VAT-registered.
• Finalised financial statements: Income statement, balance sheet, and notes. For businesses with revenue above AED 50 million, these must be audited.
• Trial balance for the full tax period, reconciled to your financial statements.
• General ledger: The FTA may request this in an audit, and it underpins every figure in the return.
• Supporting schedules: For deductions, additions, exempt income, losses carried forward, and any reliefs or elections being claimed.
• Related-party transaction records: If your business has intercompany dealings, the Transfer Pricing Disclosure Form is part of the return and you will need aggregate values and methodology notes.

If your financials are not yet finalised, get them done first. Filing with draft numbers and amending later is possible, but it creates additional risk and administration.

Step-by-Step: Filing on EmaraTax

Log into EmaraTax at eservices.tax.gov.ae using your registered credentials.

Step 1 — Open the Corporate Tax tile. From the main dashboard, select the Corporate Tax tile. Your registered entities and active tax periods will appear here.

Step 2 — Select your tax period. Choose the period you are filing for — for most businesses, this will be 01/01/2025 to 31/12/2025.

Step 3 — Complete taxpayer details. Confirm your entity type, financial year, accounting standard used (IFRS is standard for most businesses), and whether you are electing for any reliefs such as Small Business Relief.

Step 4 — Enter accounting profit. Input your net profit before tax as per your financial statements. This is the starting point for the tax computation — not your final taxable income.

Step 5 — Apply adjustments. Work through each adjustment category:

• Add back non-deductible expenses — fines, personal costs, the 50% disallowance on entertainment.
• Deduct exempt income — qualifying dividends, gains on Participating Interests.
• Apply any available prior-period losses (up to 75% of taxable income per period).
• Apply transfer pricing adjustments for related-party transactions not at arm's length.

Step 6 — Tax computation. EmaraTax calculates the tax automatically once adjusted taxable income is entered. The first AED 375,000 is at 0%; any amount above is taxed at 9%.

Step 7 — Complete the Transfer Pricing Disclosure Form. All taxable persons with related-party transactions fill this in as part of the return — categories, values, and pricing methods.

Step 8 — Review. Check every section before proceeding. Cross-reference each key figure against your financial statements. The review screen is your last opportunity to catch an error before the return becomes final.

Step 9 — Submit and pay. Submit the return, then settle any tax liability on the same date via bank transfer using your GIBAN, or by card through EmaraTax.

How Taxable Income Is Calculated

UAE Corporate Tax starts with your accounting profit, the net profit on your income statement and then applies a set of upward and downward adjustments before arriving at taxable income.

The rate structure is straightforward:

• 0% on the first AED 375,000 of taxable income.
• 9% on taxable income above AED 375,000.

This means a business with AED 400,000 in taxable income does not pay 9% on the full amount, only on the AED 25,000 above the threshold, which works out to AED 2,250 in tax.

If your adjusted taxable income is nil or negative, you still file the return. A loss position does not eliminate the filing obligation, and carried-forward losses have documentation requirements of their own.

If your revenue is at or below AED 3 million and you qualify for Small Business Relief, you can elect to treat your taxable income as nil for this period but you must actively make that election in the return. SBR is a transitional measure available for tax periods ending on or before 31 December 2026, so this is one of the last cycles in which it applies.

Paying Your Liability

Payment is due on the same date as the return which is 30 September 2026 for 31 December 2025 year-ends. There is no separate, later window for settling what you owe.

Two payment methods are accepted through EmaraTax:

• GIBAN bank transfer: Use the unique government IBAN assigned to your tax account. Always quote the reference correctly so the payment is matched to your entity.
• Card payment: available directly within the EmaraTax portal.

If your return shows no tax due, you still complete the payment step. The portal requires you to confirm a nil liability before the return is treated as fully submitted.

Common Filing Errors to Avoid

Most CT return mistakes are avoidable with preparation. These are the ones that come up most often:

• Filing from draft or unreconciled books. The return ties directly to your financials. If the trial balance is not closed and reconciled before you start, every figure you enter carries that error forward.
• Missing the Transfer Pricing Disclosure Form. This is mandatory for any business with related-party transactions, regardless of how routine or immaterial those transactions appear.
• Incorrectly classifying exempt income. Not every dividend or investment gain is automatically exempt. Specific conditions apply, particularly for Participating Interests.
• Forgetting Small Business Relief is not automatic. If you are eligible and want SBR, you must elect it in the return. Businesses that assume it applies without electing it default to the standard regime.
• Overlooking prior losses. If your business ran at a loss in an earlier post-June 2023 tax period, those losses can reduce taxable income now up to 75% of taxable income in the current year.
• Assuming a nil-tax position means no filing. If you are registered, you file even when no tax is owed.

Miss 30 September? Here Is What It Costs

Missing the deadline is not a minor administrative issue. Under the penalty framework revised by Cabinet Decision No. 129 of 2025, effective 14 April 2026, late filing attracts a fixed penalty per return and late payment accrues interest on the unpaid amount at approximately 14% per annum. These penalties run in parallel — a business that files late and pays late accumulates both.

If you have already missed the deadline, your options are to file immediately and minimize further accumulation, or to review whether a voluntary disclosure or reconsideration request is appropriate given your specific circumstances. The right advice depends on the facts but doing nothing is always the most expensive choice.

Frequently Asked Questions

Do I need to file if I owe 0% corporate tax?
Yes. Every registered taxable person must file a return for each tax period, regardless of whether any tax is actually due. The FTA has confirmed this applies even to nil and loss-making entities.

Do free zone companies have to file?
Yes. Free zone entities must register and file annually — including those claiming Qualifying Free Zone Person status and applying the 0% rate on qualifying income.

What is the deadline for the 2026 CT return?
For businesses with a 31 December 2025 financial year-end, the return and payment are both due on 30 September 2026.

Do I need audited financial statements to file?
Audited financials are mandatory if your revenue exceeds AED 50 million, or if you are claiming QFZP status. Below AED 50 million, they are not legally required for standard filers but reviewed or internally prepared accounts must be properly maintained and ready for FTA inspection.

Can I file the return myself?
Yes, if your books are clean, your entity situation is straightforward, and you understand how adjustments and elections work. If you have related-party transactions, multiple revenue streams, a free zone structure, or you are not sure which regime applies, professional support significantly reduces the risk of an error that is costly to correct.
