3. Step-by-Step Corporate Tax Filing Checklist

Follow these 7 essential steps to prepare and file your UAE corporate tax return correctly in 2026:

Step 1: Register for Corporate Tax on the FTA Portal

• Visit the FTA e-Services Portal

• Log in using your existing credentials or create a new account

• Complete the Corporate Tax Registration Form

• Attach required documents (trade license, passport copies, MOA)

Important: All taxable persons must register—even if currently benefiting from the 0% rate.

Step 2: Determine Your Taxable Income

You must calculate your taxable income in accordance with the UAE Corporate Tax Law, based on IFRS-compliant financial statements.

• Include revenue, cost of sales, and allowable expenses

• Adjust for exempt income (e.g., certain dividends, qualifying intra-group transactions)

• Carry forward any tax losses, if applicable

💡 Pro Tip: Small businesses under AED 3 million annual revenue (until 2026) may benefit from the Small Business Relief.

Step 3: Prepare Financial Statements

Your financial statements must reflect a true and fair view of your business operations and comply with International Financial Reporting Standards (IFRS).

• Balance Sheet

• Income Statement

• Cash Flow Statement

• Notes to the Financials

Auditing Requirement: Not mandatory for all, but strongly advised. Qualifying Free Zone Persons may require audited accounts for exemption eligibility.

Step 4: Review Transfer Pricing Compliance

If you transact with related parties or connected persons, ensure you’re compliant with Transfer Pricing (TP)regulations.

You may need to:

• Submit a Disclosure Form with your tax return

• Maintain Local and Master Files (if meeting threshold conditions)

• Justify that transactions are at arm’s length

See: FTA Transfer Pricing Guide

Step 5: File Your Corporate Tax Return

Once your calculations and documents are ready:

Step 6: Pay Any Tax Due

After filing, pay your corporate tax liability through the FTA portal by the same deadline.
