Corporate Tax Filing in UAE 2026 — Complete Guide for Mainland and Free Zone Businesses

Corporate Tax was introduced in the UAE on 1 June 2023 under Federal Decree-Law No. 47 of 2022. Now that the first full tax periods are coming to a close, thousands of UAE businesses are facing their first Corporate Tax filing deadline — and many are unsure where to start.

This complete guide covers everything you need to know about Corporate Tax filing in the UAE in 2026 — who must file, when to file, how to file on EmaraTax, what documents you need, and the penalties for getting it wrong.

What Is Corporate Tax Filing?

Corporate Tax filing is the process of submitting an annual Corporate Tax Return to the Federal Tax Authority (FTA) through the EmaraTax portal. The return reports your business's taxable income, allowable deductions, and the resulting tax liability for the financial year.

Even if your business owes zero tax, you are still legally required to file a return before your deadline.

Who Must File a Corporate Tax Return in UAE?

The following must file a Corporate Tax Return with the FTA:

• UAE resident juridical persons — all mainland and free zone companies registered in the UAE
• Natural persons with annual business revenue exceeding AED 1 million
• Non-resident persons with a UAE permanent establishment
• Qualifying Free Zone Persons (QFZPs) — even those benefiting from the 0% rate must file

Important: There are no exemptions from the filing obligation. Even if your taxable income is zero, or you qualify for Small Business Relief, you must still submit a return.

Don't know your tax period? Your first tax period started on 1 June 2023 or on your company's incorporation date if later. Contact us for a free consultation to confirm your deadline.

What Is Small Business Relief?

Businesses with revenue of AED 3 million or less for the tax period may elect Small Business Relief, which treats their taxable income as zero — meaning no Corporate Tax is payable.

Conditions for Small Business Relief:

• Revenue must not exceed AED 3 million in the current and all previous tax periods from 1 June 2023
• The business must be a UAE resident person
• The business must not be a Qualifying Free Zone Person
• Must be elected in the tax return — it is not automatic

Even if you elect Small Business Relief, you must still file a Corporate Tax Return.

How to File Corporate Tax Return on EmaraTax — Step by Step

Step 1 — Log in to EmaraTax

Go to emara.tax.gov.ae and log in with your UAE Pass or registered credentials.

Step 2 — Select Your Entity

Choose your registered business entity and navigate to the Corporate Tax section.

Step 3 — Prepare Your Financial Statements

You will need your Profit & Loss statement and Balance Sheet for the tax period. These should be prepared in accordance with IFRS or another accepted accounting standard.

Step 4 — Complete the Tax Return

Fill in the required sections:

• Revenue and gross income
• Allowable deductions and expenses
• Related party transactions (if applicable)
• Small Business Relief election (if eligible)
• Exempt income (if applicable)
• Taxable income calculation
• Tax payable

Step 5 — Review and Submit

Review the completed return carefully before submission. Once submitted, corrections require an amended return.

Step 6 — Pay Any Tax Due

If tax is payable, it must be paid through the EmaraTax portal by the filing deadline. Late payment attracts additional penalties.

Documents Required for Corporate Tax Filing

• Audited or management financial statements (P&L and balance sheet)
• Bank statements for the full financial year
• Trade licence copy
• Corporate Tax TRN and EmaraTax login credentials
• Details of any related party transactions (if applicable)
• Supporting documents for deductions claimed

Common Mistakes to Avoid When Filing Corporate Tax

1. Missing the 9-Month Deadline

The most common mistake. Many businesses don't realise their deadline has passed until they receive an FTA notice. Mark your deadline in your calendar now.

2. Not Electing Small Business Relief

If your revenue is AED 3 million or less, you may be leaving money on the table by not electing Small Business Relief. We assess your eligibility as part of our service.

3. Filing a Nil Return Without Supporting Records

Even if your taxable income is zero, you must maintain financial records to support your return. Keep all invoices, bank statements, and financial statements for a minimum of 7 years.

4. Incorrectly Treating Exempt Income

Income from dividends, capital gains, and certain free zone activities may be exempt from Corporate Tax — but only if specific conditions are met. Incorrectly claiming exemptions can result in penalties.

5. Ignoring Related Party Transactions

If your business transacts with related parties (subsidiaries, holding companies, or controlled entities), transfer pricing rules apply. These must be disclosed in your tax return.

Corporate Tax Filing for Free Zone Companies

Free zone companies that qualify as Qualifying Free Zone Persons (QFZPs) benefit from a 0% Corporate Tax rate on their qualifying income. However:

• They must still register for Corporate Tax
• They must still file an annual return
• They must maintain substance requirements in the free zone
• Any non-qualifying income is taxed at 9%

Failing to file — even as a QFZP — attracts the same penalties as mainland companies.
