DEADLINE ALERT
If your financial year ended on 31 December 2025, your corporate tax filing and payment deadline is 30 September 2026 — just weeks away. This guide walks you through every step to file on time and avoid penalties.
Corporate tax filing in the UAE is no longer optional or future-tense — it is a live compliance obligation that applies to virtually every business operating in the country. Under Federal Decree-Law No. 47 of 2022, all taxable persons must file annual corporate tax returns through the Federal Tax Authority’s EmaraTax portal, regardless of whether they owe any tax. With the 30 September 2026 deadline fast approaching for businesses with a December year-end, understanding the corporate tax filing process in the UAE has never been more urgent.
This guide provides a complete, step-by-step walkthrough of the corporate tax filing process in the UAE for 2026, covering who must file, which documents you need, how to navigate EmaraTax, what penalties to avoid, and how to make the most of available reliefs such as Small Business Relief.
WHAT IS CORPORATE TAX FILING IN THE UAE?
Corporate tax filing is the process of declaring your business’s taxable income to the Federal Tax Authority (FTA) and paying any tax due within the prescribed deadline. The UAE introduced corporate tax effective for financial periods starting on or after 1 June 2023, with the standard rate set at 9% on taxable income exceeding AED 375,000 and 0% on income up to that threshold.
Filing is done exclusively through the FTA’s digital platform, EmaraTax, which replaced the previous e-Services portal. Every registered taxable person — whether a mainland LLC, a free zone entity, a branch of a foreign company, or a natural person with business turnover above AED 1,000,000 — must submit a corporate tax return for each tax period. This obligation applies even if your taxable income is zero or you are claiming Small Business Relief.
KEY POINT
A corporate tax return must be filed even if no tax is payable. Failing to file a nil return still triggers late-filing penalties of AED 500 per month.
WHO MUST FILE A CORPORATE TAX RETURN IN THE UAE?
The filing obligation is broad. You must file a UAE corporate tax return if you fall into any of the following categories:
Juridical persons incorporated or managed in the UAE:
This includes all mainland and free zone companies — LLCs, sole establishments, private and public joint stock companies, branches, and partnerships. Your worldwide income is subject to UAE corporate tax, with a credit mechanism for foreign taxes paid.
Natural persons with business turnover exceeding AED 1,000,000:
Under Cabinet Decision No. 49 of 2023, freelancers and sole traders earning above this threshold from business or professional activities must register and file. Investment and employment income are excluded from this calculation.
Non-residents with a Permanent Establishment or nexus in the UAE:
Foreign entities earning UAE-sourced income through a fixed place of business, a dependent agent, or a sufficient economic nexus must also file.
Qualifying Free Zone Persons (QFZPs):
Even though QFZPs benefit from a 0% rate on qualifying income, they must file a return declaring both qualifying and non-qualifying income. QFZPs are also required to maintain audited financial statements regardless of their revenue.
The only entities exempt from filing are those specifically excluded under the law — government entities, certain extractive businesses, qualifying pension funds, and approved public benefit organisations. If you hold an active corporate tax registration, you must file.
KEY CORPORATE TAX FILING DEADLINES FOR 2026
The UAE corporate tax law grants businesses nine months from the end of their tax period to file a return and settle any tax liability. Both the filing and payment deadlines are the same date.
Financial Year Ending: 31 December 2025
Filing & Payment Deadline: 30 September 2026
Financial Year Ending: 31 March 2026
Filing & Payment Deadline: 31 December 2026
Financial Year Ending: 30 June 2026
Filing & Payment Deadline: 31 March 2027
Financial Year Ending: 30 September 2026
Filing & Payment Deadline: 30 June 2027
IMPORTANT
If 30 September falls on a weekend or public holiday, the FTA generally does not extend the deadline automatically. File well in advance to avoid last-minute portal congestion and payment delays.
For businesses that started operations after 1 June 2023 and have a non-standard first tax period, your specific deadline is shown in your EmaraTax account. Always verify your deadline there rather than relying on general tables.
STEP-BY-STEP GUIDE TO FILING CORPORATE TAX VIA EMARATAX
The entire corporate tax filing process is conducted digitally through the FTA’s EmaraTax portal. Here is a detailed walkthrough:
Step 1 — Log into EmaraTax
Visit emaratax.tax.gov.ae and sign in using your registered credentials (UAE Pass or EmaraTax login). If you have not registered for corporate tax yet, you must do so before filing — late registration carries a flat AED 10,000 penalty.
Step 2 — Select the correct tax period
Navigate to the Corporate Tax section and select the tax period matching your financial year. Double-check the dates — selecting the wrong period is one of the most common filing errors, particularly for first-time filers.
Step 3 — Enter your financial data
Input your revenue, cost of goods sold, gross profit, operating expenses, and net profit from your audited or prepared financial statements. The return form requires figures to reconcile from accounting profit to taxable income, including adjustments for exempt income, non-deductible expenses, and reliefs.
Step 4 — Apply reliefs and elections
Declare any applicable reliefs, including Small Business Relief (for businesses with revenue up to AED 3,000,000), free zone qualifying income elections, or transitional relief under Ministerial Decision No. 120 of 2023.
Reliefs are not applied automatically — you must actively elect them in each return.
Step 5 — Disclose related-party transactions
If your business has transactions with related parties or connected persons, you must provide details in the designated schedule. Under Articles 34–36 of the CT Law and Ministerial Decision No. 97 of 2023, all such transactions must be at arm’s length.
Businesses meeting the thresholds must also maintain Transfer Pricing documentation (Master File, Local File, and Country-by-Country Report for groups above AED 3.15 billion in consolidated revenue).
Step 6 — Upload supporting documents
Attach your financial statements and any required schedules. The document requirements depend on your revenue tier:
Below AED 3 million:
Revenue declaration, EmaraTax credentials, CT registration number.
AED 3M – AED 50M:
Income statement, balance sheet, expense schedules, related-party details.
Above AED 50 million:
All of the above plus audited financial statements from an MoE-approved auditor.
All QFZPs (any revenue):
Audited financial statements are mandatory regardless of revenue.
Step 7 — Review and submit
Carefully verify every figure before clicking submit. Once submitted, download and retain your filing confirmation receipt. Amendments after submission may require filing a revised return and could attract FTA scrutiny.
Step 8 — Pay any tax due
If your return shows a tax liability, payment must be made by the same deadline via card or bank transfer to your FTA-generated GIBAN (Government International Bank Account Number).
Filing on time but paying late still triggers the late payment penalty.
COMMON MISTAKES TO AVOID WHEN FILING CORPORATE TAX
After two full years of the UAE corporate tax regime, the FTA has developed a clear picture of recurring filing errors. Avoid these costly mistakes:
- Assuming no tax means no filing requirement.
Even if your taxable income is zero or below AED 375,000, you must still file a return. The filing obligation and the tax liability are separate.
- Miscalculating the nine-month deadline.
The nine months run from the end of your financial year, not from the date of your tax registration or trade licence renewal. For a 31 December year-end, the deadline is 30 September — not 30 September of the following year.
- Forgetting to elect Small Business Relief.
If you qualify for the AED 3,000,000 Small Business Relief, you must actively elect it in each return. The relief is available through 31 December 2029, but missing the election means you lose it for that period.
- Electing Small Business Relief in a loss-making year.
Claiming the relief in a year when you have tax losses forfeits your ability to carry forward those losses to offset future profits. Strategically, it may be better to file normally and bank the losses.
- Mixing qualifying and non-qualifying free zone income.
QFZPs must segregate qualifying income (taxed at 0%) from non-qualifying income (taxed at 9%). Commingling these in your records can jeopardise your entire QFZP status.
- Omitting related-party disclosures.
The FTA’s 2026 clarifications emphasise that transfer pricing adjustments must be properly reflected in the return. Failure to disclose related-party transactions is a red flag for FTA audits.
- Deducting non-allowable expenses.
Fines, penalties, donations to non-qualifying entities, and entertainment expenses exceeding 50% of the total are not deductible. Including them in your deductions will result in an incorrect return.
- Filing on unaudited figures when audited statements are required.
Businesses with revenue above AED 50 million and all QFZPs must use audited financial statements. Filing without them is non-compliant.
- Missing the transitional relief election.
Under Ministerial Decision No. 120 of 2023, businesses can elect either the Valuation Method or Time Apportionment Method to avoid double taxation on pre-CT gains. This election must be made in the first corporate tax return — if you missed it last year, this opportunity is gone permanently.
- Paying late despite filing on time.
Filing and payment are separate obligations with the same deadline. Late payment now attracts a 14% per annum charge under Cabinet Decision No. 129 of 2025 (effective 14 April 2026), up from the previous fixed penalty structure.
UAE CORPORATE TAX FILING PENALTIES: WHAT YOU RISK
The FTA enforces a structured penalty regime for non-compliance. Understanding these penalties is critical for every business filing corporate tax in the UAE:
Late tax registration:
AED 10,000 (flat)
Late filing (first 12 months):
AED 500 per month or part thereof
Late filing (month 13 onwards):
AED 1,000 per month or part thereof
Late payment of tax:
14% per annum (Cabinet Decision No. 129/2025)
Failure to maintain records:
AED 10,000 (first offence), AED 20,000 (repeat)
Penalties accumulate and compound. A business that fails to register, then files late and pays late, could face AED 10,000 for registration plus AED 6,000 for twelve months of late filing plus the 14% annual interest on the unpaid tax.
For a business owing AED 500,000 in tax, the late payment charge alone would be AED 70,000 per year.
PENALTY WAIVER
The FTA may waive the late registration penalty of AED 10,000 if the first tax return is submitted within seven months of the end of the first tax period. If you registered late, filing promptly can save you this amount.

FREQUENTLY ASKED QUESTIONS
Do I need to file a corporate tax return if my income is below AED 375,000?
Yes. The AED 375,000 threshold determines whether you owe tax, not whether you need to file. Every registered taxable person must submit a return for each tax period, even if the taxable income is zero. Failure to file a nil return triggers late-filing penalties of AED 500 per month.
What is the corporate tax filing deadline for businesses with a December 2025 year-end?
The deadline is 30 September 2026. Under UAE corporate tax law, businesses have nine months from the end of their tax period to file a return and pay any tax due. Both obligations share the same deadline.
Can I file my corporate tax return myself, or do I need a tax agent?
Technically, any authorised signatory can file through EmaraTax. However, given the complexity of adjustments, elections, transfer pricing disclosures, and the penalty risks for errors, most businesses in the UAE engage an FTA-registered tax agent or consultant. This is especially important for businesses with revenue above AED 3 million, those with related-party transactions, or QFZPs. Tax Falcon is an FTA-approved tax agent that handles end-to-end filing.
What happens if I file late but owe no tax?
You will still incur a late-filing penalty of AED 500 per month for the first twelve months and AED 1,000 per month thereafter. The penalty applies to the act of late filing, not to the amount of tax owed. Filing obligation and tax liability are separate.
Has the late payment penalty changed in 2026?
Yes. Under Cabinet Decision No. 129 of 2025, effective 14 April 2026, the late payment penalty is now 14% per annum on the outstanding tax amount. This replaced the previous fixed penalty structure and significantly increases the cost of delaying payment, particularly for larger tax liabilities.
