Filing Your First UAE Corporate Tax Return: Complete Guide (2026)

If your first tax period ended 31 December 2025, your first UAE corporate tax return is due by 30 September 2026 — and by 31 July 2026 if you registered late and want the AED 10,000 penalty waived. The return reports your accounting income, applies UAE corporate tax adjustments, and computes 9% tax on taxable income above AED 375,000.

Who is filing for the first time in 2026?

Two large groups. First, businesses incorporated or licensed in 2024–2025 whose first tax period recently closed. Second, businesses whose first period ended 31 December 2025 because their financial year starts in January. Both groups face the same 9-month rule.

Natural persons — freelancers and sole establishments — join them if business turnover exceeded AED 1 million in the calendar year /tax/guides/corporate-tax-registration-natural-persons.

The five things to get right

1. Confirm your first tax period. It is defined by your financial year and can run 6 to 18 months for new entities. Your deadline is 9 months from its end — verify it /tax/tools/deadline-checker.

2. Check the 31 July waiver date. If you registered for corporate tax after your deadline, filing your first return within 7 months of your first period's end wipes the AED 10,000 late registration penalty automatically. For a 31 December 2025 period end, that is 31 July 2026 /tax/guides/corporate-tax-late-registration-penalty-waiver.

3. Decide on Small Business Relief. If revenue is AED 3 million or below (this period and every earlier one), you can elect Small Business Relief and be treated as having no taxable income — but only for periods ending on or before 31 December 2026, and only by electing in the return /tax/guides/small-business-relief-uae-explained.

4. Prepare compliant accounts. IFRS is the default basis. Cash basis accounting is permitted where revenue does not exceed AED 3 million. Audited financial statements are mandatory above AED 50 million revenue and for all Qualifying Free Zone Persons.

5. Keep the records. Everything supporting the return must be retained for 7 years. Failure to keep records carries an AED 10,000 penalty, doubling on repeat.

What the first return actually contains

Accounting income, then adjustments: exempt income out, non-deductible expenses back in (fines, 50% of entertainment, non-qualifying donations), interest deduction limitation where relevant, reliefs and elections, and disclosure schedules for related-party dealings. The result is taxable income; tax is 0% up to AED 375,000 and 9% above it. Estimate yours /tax/tools/tax-calculator.

The 7 most common first-return mistakes

Missing the Small Business Relief election; assuming a loss means no filing; free zone entities assuming 0% means exemption from filing; using draft accounts; ignoring the transfer pricing disclosure; leaving payment past the deadline (14% per annum accrues monthly); and starting in September for a September deadline.
