By: Tax Falcon UAE — FTA-Approved Tax Advisors (Reg. No. 20056800)

Urgent Deadline Alert

If your business has a financial year ending 31 December 2025, your UAE corporate tax deadline is 30 September 2026. With just 15 days remaining, now is the time to finalise your CT return on the EmaraTax portal.

Missing this date triggers automatic penalties starting at AED 500 per month, while the new 14% per annum late payment charge applies from day one.

The Federal Tax Authority (FTA) has issued a public reminder urging all taxable persons to file their corporate tax returns before the UAE corporate tax deadline of 30 September 2026. This filing date applies to businesses whose first or second tax period ended on 31 December 2025 under Federal Decree-Law No. 47 of 2022.

Whether you are a mainland LLC, a freezone entity, or a sole proprietor above the AED 1,000,000 turnover threshold, the clock is ticking.

In this comprehensive guide, Tax Falcon UAE breaks down everything you need to know about the 2026 corporate tax filing deadline — from exact due dates and penalty amounts to a step-by-step EmaraTax filing walkthrough and last-minute compliance actions that could save your business thousands of dirhams.

What Is the UAE Corporate Tax Deadline?

The UAE corporate tax deadline refers to the date by which a taxable person must file their corporate tax return and settle any tax liability with the FTA.

Under Article 48 of Federal Decree-Law No. 47 of 2022, every taxable person must file a CT return within nine months from the end of the relevant tax period.

For the vast majority of UAE businesses operating on a calendar-year basis, with a financial year ending 31 December 2025, this means the filing and payment deadline is 30 September 2026.

However, different financial year-end dates produce different deadlines:

Financial Year End	CT Return Deadline	Status
30 June 2025	31 March 2026	Already passed
30 September 2025	30 June 2026	Already passed
31 December 2025	30 September 2026	15 days remaining
31 March 2026	31 December 2026	Upcoming
30 June 2026	31 March 2027	Upcoming

It is critical to confirm your exact deadline on the EmaraTax portal, as the FTA uses the tax period registered on your profile — not your trade licence date — to calculate your due date.

Who Does This Apply To?

The September 30 UAE corporate tax deadline applies to every person subject to corporate tax under the CT Law. This includes:

Juridical persons

Juridical persons incorporated or effectively managed and controlled in the UAE, including mainland LLCs, private joint-stock companies, branches of foreign companies with a permanent establishment, and freezone entities, including those claiming QFZP status under 0% tax on qualifying income.

Natural persons

Natural persons conducting business activities in the UAE with annual turnover exceeding AED 1,000,000 under Cabinet Decision No. 49 of 2023. This covers freelancers, sole proprietors, and partners in unincorporated partnerships above the threshold.

Exempt persons

Exempt persons who have obtained an FTA exemption, including government entities, qualifying investment funds, pension funds, and extractive businesses, must still file a CT return confirming their exempt status, even though no tax is payable.

Failing to file the return by the UAE corporate tax deadline still triggers late filing penalties.

Key Point

Even businesses eligible for Small Business Relief, with revenue up to AED 3,000,000, must file a simplified CT return by the deadline.

Electing for SBR does not exempt you from filing — it only reduces your taxable income to zero.

Key Rules and Requirements for the 2026 Filing

The 2026 filing season brings several important rules and recent changes that every business should understand before submitting their CT return.

Corporate Tax Rates

Under Federal Decree-Law No. 47 of 2022, the standard rates remain:

0% on taxable income up to AED 375,000
9% on taxable income exceeding AED 375,000

Qualifying Free Zone Persons (QFZPs) pay 0% on qualifying income and 9% on non-qualifying income.

New Late Payment Penalty — 14% Per Annum

Cabinet Decision No. 129 of 2025, effective 14 April 2026, introduced a restructured late payment penalty of 14% per annum, charged daily from the date the payment was due with no ceiling.

For a business with an AED 500,000 tax liability that pays three months late, this amounts to approximately AED 17,500 in interest penalties alone — on top of the late filing fines.

Transfer Pricing Documentation

Businesses with related-party transactions must ensure their transfer pricing documentation, including the Master File and Local File, is prepared by the filing date.

Under Articles 34–36 of the CT Law and Ministerial Decision No. 97 of 2023, the arm’s length principle applies to all Related Party and Connected Person transactions.

Country-by-Country Reporting (CbCR) applies to groups with consolidated revenue exceeding AED 3.15 billion.

QFZP AUP Report Requirement

Under FTA Decision No. 6 of 2026, QFZPs distributing revenue between qualifying and non-qualifying activities must submit an Agreed-Upon Procedures (AUP) Report) within 30 days of filing the CT Return.

If you file on 30 September 2026, your AUP Report is due by 30 October 2026.

Transitional Relief — Last Chance

Ministerial Decision No. 120 of 2023 provides transitional relief to prevent double taxation on pre-CT gains.

The election for the valuation or time apportionment method must be made in the first CT Return.

For businesses filing their first-ever return in this period, missing the election means losing the relief permanently. This could cost hundreds of thousands — or even millions — of dirhams for businesses holding appreciated assets.

Step-by-Step Guide to Filing Before September 30

Follow these steps to ensure your CT return is filed accurately and on time:

1. Log in to the EmaraTax Portal

Access the EmaraTax portal using your UAE Pass credentials. Navigate to Corporate Tax, then select “File CT Return” for the relevant tax period.

2. Finalise Your Financial Statements

Ensure your audited or certified financial statements for the year ending 31 December 2025 are complete.

These form the basis of your tax return and must reconcile with the figures you report.

3. Identify Disallowable Expenses

Remove non-deductible items including:

Fines and penalties
Personal expenses
Entertainment expenses exceeding the 50% deduction limit
Donations to non-qualifying entities
Interest expenses subject to the general interest deduction limitation rules

4. Calculate Taxable Income

Start with accounting net profit and make adjustments for exempt income, disallowable expenses, and any available reliefs.

Apply the 0% rate on the first AED 375,000 and 9% on the remainder.

5. Claim Reliefs and Elections

Elect for Small Business Relief if eligible, with revenue of AED 3,000,000 or below.

Claim transitional relief if this is your first return, apply for Tax Group treatment if you meet the 95% ownership threshold, and ensure any carried-forward losses are properly documented.

6. Prepare Transfer Pricing Documentation

If you have related-party transactions, your Local File and Master File should be ready.

Ensure the five approved methods — CUP, RPM, CPM, TNMM, and PSM — are applied correctly and the most appropriate method is documented.

7. Submit and Pay

Review the return for accuracy, submit electronically through EmaraTax, and pay any CT liability due.

Keep the filing confirmation and payment receipt for your records.

Businesses must retain records for a minimum of seven years.

Pro Tip

Do not wait until 30 September to file.

The EmaraTax portal can experience heavy traffic near deadlines, and technical issues could prevent timely submission. File at least one week early to avoid last-minute problems.

Common Mistakes to Avoid

Missing the Transitional Relief Election

Many businesses are filing their first-ever CT return this period.

Failing to elect the Valuation Method or Time Apportionment Method in this return means the relief is lost forever.

For a property bought at AED 147 million, valued at AED 500 million at transition, and later sold at AED 550 million, this election could save approximately AED 32 million in corporate tax.

Confusing Filing with Payment

Both the CT return and the tax payment are due by the same date — 30 September 2026.

Filing the return without paying the tax still triggers the 14% per annum late payment penalty from 1 October 2026 onward.

Ignoring QFZP Compliance Requirements

Freezone businesses claiming 0% cannot simply tick a box.

They must meet the de minimis test, adequate substance requirements, and prepare for the AUP Report within 30 days of filing.

Non-compliance means losing QFZP status retroactively — and owing 9% on all income.

Forgetting to Register First

If you have not yet registered for corporate tax with the FTA, you cannot file a return.

Late registration carries a flat penalty of AED 10,000.

Not Accounting for the New Penalty Framework

The 14% per annum late payment charge under Cabinet Decision No. 129 of 2025 is significantly higher than many businesses expect.

Unlike the old regime, there is no ceiling on this penalty — it accrues daily until the full amount is paid.

Overlooking Natural Person Obligations

Freelancers and sole proprietors with turnover exceeding AED 1,000,000 are subject to CT.

Many individuals remain unaware of this requirement under Cabinet Decision No. 49 of 2023 and risk both registration and filing penalties.

Full Penalty Schedule for Missing the UAE Corporate Tax Deadline

Violation	Penalty Amount	Legal Basis
Late CT Registration	AED 10,000 (flat)	Federal Decree-Law No. 28/2022
Late CT Return Filing (months 1–12)	AED 500 per month	Federal Decree-Law No. 47/2022
Late CT Return Filing (month 13+)	AED 1,000 per month	Federal Decree-Law No. 47/2022
Late CT Payment	14% per annum (no ceiling)	Cabinet Decision No. 129/2025
Failure to Maintain Records	AED 10,000 first / AED 20,000 repeat	Federal Decree-Law No. 28/2022
Inaccurate CT Return	Percentage of underpaid tax	Federal Decree-Law No. 28/2022

For a business that misses the 30 September UAE corporate tax deadline by six months, the combined penalties could include AED 3,000 in late filing fines (6 × AED 500) plus 14% per annum on the unpaid tax liability.

For a tax bill of AED 200,000, that adds approximately AED 14,000 in late payment charges — totalling AED 17,000 in avoidable penalties.

Frequently Asked Questions

What happens if I miss the September 30, 2026 corporate tax deadline?

Missing the UAE corporate tax deadline triggers two separate penalties:

Late filing penalty of AED 500 per month for the first 12 months
AED 1,000 per month thereafter
Late payment penalty of 14% per annum on unpaid tax, charged daily with no cap

Both penalties begin from 1 October 2026 and continue until you file and pay in full.

Can I get an extension on the corporate tax filing deadline?

The FTA does not currently offer a general extension mechanism for CT return deadlines.

The nine-month window from the end of your tax period is fixed under the CT Law.

If you anticipate difficulty meeting the deadline, contact an FTA-approved tax agent immediately to expedite your filing.

Do freezone companies need to file by September 30 too?

Yes.

All freezone companies — whether they claim QFZP status at 0% or not — must file a CT return by the same deadline applicable to their financial year end.

A freezone company with a 31 December 2025 year-end must file by 30 September 2026.

Additionally, QFZPs must submit their AUP Report within 30 days of filing under FTA Decision No. 6 of 2026.

Is the September 30 deadline for payment as well as filing?

Yes.

Both the CT return submission and payment of any corporate tax due must be completed by 30 September 2026.

There is no separate payment deadline. If you file on time but pay late, the 14% per annum late payment penalty under Cabinet Decision No. 129 of 2025 applies from 1 October 2026.
