Is Corporate Tax mandatory for all UAE businesses?

Yes. Every UAE business that is a taxable person must register for Corporate Tax with the FTA and file a return, whatever its profit. Taxable income up to AED 375,000 is taxed at 0% and income above that at 9%. Businesses with revenue of AED 3 million or less may elect Small Business Relief for eligible tax periods. Free zone companies must meet the Qualifying Free Zone Person conditions to benefit from the 0% rate.

How long does VAT registration take in the UAE?

VAT registration in the UAE typically takes 3 to 5 working days when all documents are correctly submitted to the Federal Tax Authority (FTA) via the EmaraTax portal. Marifah Tax Advisory completes VAT registrations within this timeframe and handles the entire process on your behalf.

What documents are needed for Corporate Tax registration in UAE?

For UAE Corporate Tax registration, you need: Trade Licence copy, Memorandum of Association (MOA), Emirates ID and passport copies of all owners/directors, company bank account details, and financial year start date. Our team guides you through the exact checklist and submits everything to the FTA on your behalf.

Can free zone companies avoid Corporate Tax in UAE?

Free zone companies are NOT automatically exempt from UAE Corporate Tax. To qualify for the 0% Qualifying Free Zone Person (QFZP) rate, your company must meet 5 specific conditions set by the FTA — including deriving income only from qualifying activities and maintaining adequate substance. We assess your eligibility and structure your compliance accordingly.

What happens if I file VAT returns late in UAE?

Late VAT return filing in UAE attracts an immediate penalty of AED 1,000 for the first offence, rising to AED 2,000 for repeated violations within 24 months. Additional penalties of 2% per month apply on any unpaid VAT. The FTA may also block your EmaraTax account. Marifah handles all filing deadlines proactively so you never face these penalties.

UAE Corporate Tax Return Filing — Step by Step

Your Corporate Tax return must be filed within 9 months of your financial year-end. Here is exactly how to file on EmaraTax — boxes explained, deadlines, and common mistakes to avoid.

What is a Corporate Tax Return?

A Corporate Tax return is the annual declaration you file with the Federal Tax Authority (FTA) declaring your taxable income, allowable deductions, and the Corporate Tax amount due for a financial year. Every UAE business that has registered for Corporate Tax must file a return — even if the tax owed is zero. The return is filed exclusively through the EmaraTax portal at tax.gov.ae.

Filing Deadline — 9 Months from Year-End

You must file your Corporate Tax return and pay any tax due within 9 months from the end of your financial year. For example: if your financial year ends 31 December 2025, your return is due by 30 September 2026. If your year ends 31 March 2026, your return is due by 31 December 2026. There are no extensions available — late filing triggers a fixed AED 500 penalty per month for the first 12 months, and AED 1,000 per month thereafter.

What You Need Before Filing

Audited or management financial statements for the full tax year

Trial balance and general ledger

List of related party transactions (transfer pricing disclosure)

Details of exempt income (dividends, capital gains under Participation Exemption)

Depreciation schedule and fixed asset register

Loan agreements (for interest deduction capping under 30% EBITDA rule)

Free zone income breakdown (qualifying vs non-qualifying) if applicable

Step 1 — Log in to EmaraTax

Go to tax.gov.ae and log in using your registered credentials. From the dashboard, select your business entity and click 'Corporate Tax' from the left-hand menu. You will see your registered tax periods listed. Click on the relevant period to begin your return.

Step 2 — Enter Your Financial Data

The return has several sections. You will enter your accounting profit or loss as per your financial statements, then make adjustments for: non-deductible expenses (entertainment above 50%, personal expenses, fines), exempt income (qualifying dividends, capital gains), and prior-year tax losses if you are carrying them forward. The system calculates your taxable income automatically.

Step 3 — Apply Reliefs and Exemptions

At this stage you elect any available reliefs. Small Business Relief (SBR) is available if your revenue does not exceed AED 3 million and the tax period ends on or before 31 December 2026 — electing SBR treats your taxable income as nil. Free Zone Persons must confirm their Qualifying Free Zone Person (QFZP) status and separately declare qualifying vs non-qualifying income. Participation Exemption applies to dividends and capital gains from qualifying shareholdings.

Step 4 — Calculate and Pay

Once all data is entered, EmaraTax calculates your tax liability. 0% applies on taxable income up to AED 375,000. 9% applies on income above AED 375,000. Any tax due must be paid within the same 9-month window as the return. Payment is made via EmaraTax using bank transfer (GIBAN), e-Dirham, or credit/debit card. There is no instalment option under the standard regime.

Most Common Filing Mistakes

Filing late — the 9-month deadline is fixed, no extensions exist

Not electing Small Business Relief when eligible

Claiming 100% of entertainment expenses (only 50% is deductible)

Not applying the 30% EBITDA cap on net interest expenses

Missing related party disclosures — FTA can impose penalties for incomplete transfer pricing documentation

Free zone companies filing as mainland — losing QFZP status unnecessarily

Forgetting to carry forward prior-year losses in the return

Penalty for Late Filing

Filing your Corporate Tax return even one day late triggers an automatic AED 500 per month penalty for the first 12 months, then AED 1,000 per month. Separately, late payment of any tax due attracts a 14% per annum penalty effective from 14 April 2026 under Cabinet Decision No. 129 of 2025. Both penalties run simultaneously — there is no grace period.
