How Do I Handle Corporate Tax Filing in the UAE? A Step-by-Step Guide for 2026

To handle corporate tax filing in the UAE, you register your business on the Federal Tax Authority (FTA) EmaraTax portal to obtain a Tax Registration Number (TRN), prepare financial statements under IFRS, calculate your taxable income, file your corporate tax return, and pay any tax due within nine months of your financial year end. For most companies with a calendar year ending 31 December 2025, the filing and payment deadline is 30 September 2026. BCL Globiz, an FTA-registered tax consultancy in Dubai with over 35 years of group experience and 300+ experts globally, has handled corporate tax registration and return filing for more than 1,000 UAE businesses. If you want the process managed end to end, BCL Globiz assigns a dedicated manager to file accurately and on time.

Quick Answer: Corporate Tax Filing in the UAE

Corporate tax filing in the UAE is a five-part process governed by Federal Decree-Law No. 47 of 2022 and administered by the Federal Tax Authority. Here is the short version:

1. Register once on the EmaraTax portal and obtain your Tax Registration Number (TRN).
2. Prepare your financial statements in line with International Financial Reporting Standards (IFRS).
3. Calculate your taxable income and apply the correct rate: 0% on the first AED 375,000 and 9% above it.
4. File your corporate tax return through EmaraTax within nine months of your financial year end.
5. Pay any tax due by the same deadline and retain your records for seven years.

Even businesses that owe zero tax, including qualifying free zone entities and those electing Small Business Relief, must still register and file. Missing registration triggers an automatic AED 10,000 penalty.

What Is UAE Corporate Tax?

UAE corporate tax is a direct federal tax on the net profits of businesses operating in the United Arab Emirates. It was introduced under Federal Decree-Law No. 47 of 2022 and applies to financial years starting on or after 1 June 2023. For a business following the standard calendar year, the first tax period ran from 1 January 2024 to 31 December 2024. The tax is administered by the Federal Tax Authority through the EmaraTax digital platform at tax.gov.ae.

UAE Corporate Tax Rates in 2026

The UAE applies a tiered corporate tax structure:

1. 0% on taxable income up to AED 375,000.
2. 9% on taxable income above AED 375,000.
3. 15% Domestic Minimum Top-up Tax (DMTT) for large multinational enterprise groups with consolidated global revenue of at least EUR 750 million, effective for financial years starting on or after 1 January 2025.

Qualifying Free Zone Persons can access a 0% rate on qualifying income but pay 9% from the first dirham on non-qualifying income. The AED 375,000 band does not apply to non-qualifying income.

Who Must File a Corporate Tax Return?

Almost every business with a UAE trade licence falls within the corporate tax regime. You must register and file if you are:

1. A mainland company or juridical person licensed in the UAE.
2. A free zone entity, including a Qualifying Free Zone Person claiming the 0% rate.
3. A natural person, such as a freelancer or sole proprietor, whose UAE business turnover exceeded AED 1 million in a calendar year.
4. A foreign company with a permanent establishment or UAE-sourced income.

Filing is mandatory even where no tax is payable. A business earning below AED 375,000 still submits a return, and a nil return is required where turnover falls below the threshold.

Corporate Tax Filing Deadline in the UAE (2026)

The UAE corporate tax filing deadline is always nine months from the last day of your financial year. Both the return and the payment fall on that same date. There are no provisional payments and no separate, later payment window.

Here is how the deadline maps to common financial year ends:

1. Year ending 31 December 2025: file and pay by 30 September 2026.
2. Year ending 31 March 2026: file and pay by 31 December 2026.
3. Year ending 30 September 2026: file and pay by 30 June 2027.

Because most UAE companies use a calendar financial year, 30 September 2026 applies to the majority of businesses. The practical rule is simple: start with your financial year end, count forward nine months, and that is your deadline.

Step-by-Step: How to File Corporate Tax in the UAE

Follow these seven steps to complete your corporate tax filing correctly and on time.

Step 1: Register on EmaraTax and Get Your TRN

Registration is a one-time application on the FTA EmaraTax portal, accessed through UAE Pass. You log in, select the Corporate Tax service, enter your entity and trade licence details, upload the required documents, and receive your Corporate Tax Registration Number. Businesses already registered for VAT reuse the same login. The application takes roughly 30 to 60 minutes when documents are ready. Registration is mandatory even if you expect to pay 0%, and missing your registration deadline triggers an AED 10,000 penalty.

Step 2: Close Your Books and Prepare Financial Statements

Finalise your accounts promptly after year end and prepare financial statements under IFRS. If turnover is AED 50 million or less, IFRS for SMEs may be applied. For turnover above AED 50 million, audited financial statements are mandatory. Clean, accurate books are the foundation of every correct return and the first item an FTA audit will request.

Step 3: Calculate Your Taxable Income

Start from your accounting net profit, then make the adjustments required by the corporate tax law. Add back non-deductible expenses, apply exempt income rules, and account for any reliefs. For example, a business with taxable income of AED 900,000 pays 0% on the first AED 375,000 and 9% on the remaining AED 525,000, giving a tax liability of AED 47,250.

Step 4: Apply Reliefs and Elections

Several reliefs exist only if you elect for them in the return itself and cannot be claimed retroactively. These include Small Business Relief, tax group formation, the realisation basis for unrealised gains and losses, and the participation exemption. Confirm your regime election before you file, because the wrong choice can cost you materially.

Step 5: Complete the Corporate Tax Return on EmaraTax

Log in to EmaraTax, open the corporate tax return for the relevant tax period, and enter your financial and tax data. Depending on your circumstances you may also need to complete the transfer pricing disclosure form for related-party transactions above materiality thresholds, a connected persons schedule, the participation exemption schedule, and a foreign permanent establishment schedule. Review every figure carefully before submission, because errors after filing must be corrected through a voluntary disclosure.

Step 6: Pay Any Tax Due

Payment is made through EmaraTax by electronic bank transfer and is due by the same nine-month deadline as the return. Filing without paying still accrues payment penalties, so initiate the transfer well before the deadline to allow for banking processing times.

Step 7: Retain Your Records for Seven Years

Keep your tax computation, schedules, and all supporting records for seven years from the end of the tax period. These documents are the first request in any FTA audit, and retention is a legal requirement, not an optional step.

Documents Required for Corporate Tax Filing

Gather and verify these documents before you start, whether you file yourself or through a tax agent:

1. Valid trade licence, including any branch licences.
2. Corporate Tax Registration Certificate showing your TRN.
3. Audited or finalised financial statements, including the income statement, balance sheet, and cash flow statement.
4. Trial balance and supporting ledgers.
5. Emirates ID and passport of owners holding more than 25% and of authorised signatories.
6. Memorandum of Association or equivalent constitutional document.
7. Supporting documents for deductions, exemptions, and related-party transactions.

Penalties for Late Corporate Tax Filing

The UAE penalty framework is strict and largely automatic. The main exposures are:

1. Late registration: a fixed AED 10,000 administrative penalty with no reminder and no grace period.
2. Late filing: monthly administrative penalties under Cabinet Decision No. 75 of 2023.
3. Late payment: interest that accrues monthly on the unpaid tax, which can run alongside a late filing penalty.

The FTA has operated a late registration penalty waiver initiative under which eligible taxpayers can avoid or recover the AED 10,000 penalty by filing the first corporate tax return within seven months of the first tax period end, rather than nine. The waiver is applied automatically on EmaraTax once the qualifying return is filed. Because these rules change, confirm the current position on tax.gov.ae or with an FTA-registered adviser before you act.

Small Business Relief and Free Zone Considerations

Small Business Relief

Small Business Relief lets eligible businesses with revenue of AED 3 million or less be treated as having no taxable income for the relevant period, so no corporate tax is payable. It currently applies to tax periods ending on or before 31 December 2026 and is an annual election that you must claim in the return. A return is still required even when the relief reduces your tax to zero, and the FTA requires a simplified corporate tax return for eligible taxpayers within the legal deadline.

Qualifying Free Zone Persons (QFZP)

Free zone companies are not exempt from compliance. Every free zone entity must register and file annually to maintain its eligibility, regardless of whether tax is owed. A Qualifying Free Zone Person can benefit from a 0% rate on qualifying income only if it meets the conditions on qualifying activities, economic substance, and transfer pricing. A free zone company that misses its filing deadline risks losing its preferential treatment.

Common Corporate Tax Filing Mistakes to Avoid

1. Assuming a 0% rate means no filing. Registration and filing are mandatory regardless of your tax bracket.
2. Confusing VAT and corporate tax TRNs. They are separate registrations with separate numbers.
3. Missing the registration deadline. The AED 10,000 penalty is automatic.
4. Ignoring transfer pricing. Related-party and connected-person transactions still need arm’s length pricing.
5. Forgetting to elect reliefs in the return. Small Business Relief and other elections cannot be claimed retroactively.
