If your company's financial year ended on 31 December 2025, your first corporate tax return is due by 30 September 2026. That sounds like plenty of time - until you start gathering seven years' worth of records, reconciling your books, and working out which deductions actually apply. Over 640,000 businesses are now registered for UAE corporate tax (Gulf News, 2025), and a large number of them are filing for the first time.
TL;DR: Your corporate tax return must be filed within nine months of your financial year end via the FTA's EmaraTax portal. The rate is 9% on taxable income above AED 375,000. Businesses earning under AED 3 million can elect Small Business Relief for 0% tax through 2026. Late filing costs AED 500 the first time, AED 1,000 for repeat offences, plus 14% annual interest on unpaid tax.
When Is Your Filing Deadline?
The FTA gives you nine months from the end of your financial year to file and pay. For calendar-year companies (January to December 2025), the deadline is 30 September 2026. If your financial year runs June to May, your first tax period likely started 1 June 2023, and the deadline falls nine months after that period ends.
Filing and payment are a single obligation. Submitting your return without settling the tax - or paying without filing - counts as non-compliance (FTA, 2024). In our experience, this catches out businesses that assume filing alone satisfies the requirement.
Do You Actually Need to File?
Yes. Every UAE tax-resident juridical person must file a corporate tax return annually, regardless of income level (PwC, 2025). That includes companies that made a loss, had no revenue, or fall within the 0% band on income up to AED 375,000.
Free zone companies registered as Qualifying Free Zone Persons also file - they just report qualifying income at the 0% rate. If you are unsure whether your free zone income qualifies, our guide on free zone corporate tax breaks down the conditions.
What Tax Rate Applies to Your Business?
The standard rate is 9% on taxable income above AED 375,000. Income up to that threshold sits in the 0% band. This is not an exemption - it is a rate band, and you still report income below the threshold on your return.
Large multinationals with consolidated global revenue exceeding AED 3.15 billion face a 15% minimum rate under OECD Pillar Two rules (Ministry of Finance, 2024). For most UAE SMEs, the 9% rate is the one that matters.
Can You Claim Small Business Relief?
If your total revenue was AED 3 million or less, you can elect Small Business Relief and be treated as having zero taxable income for the period (FTA, 2023). This effectively means 0% corporate tax.
There are conditions. You must actively elect SBR when filing your return - it does not apply automatically. If your revenue exceeded AED 3 million in any prior tax period, you lose eligibility. And SBR only covers tax periods ending on or before 31 December 2026 (Ministry of Finance, 2023), so it is a temporary measure. What we see most often is businesses assuming they qualify without checking the prior-period rule, then finding out they owe tax they had not planned for.
What Documents Do You Need?
Gather these before you log into EmaraTax:
- Financial statements prepared under IFRS (balance sheet, income statement, cash flow statement)
- General ledger, trial balance, and bank reconciliations
- Corporate Tax Registration Certificate and your Tax Registration Number (TRN)
- Supporting documents for any claimed deductions or exemptions
- Audit report with auditor name and opinion (mandatory if revenue exceeds AED 50 million)
The FTA requires you to keep all records for seven years from the end of the relevant tax period (FTA Corporate Tax Law, 2022). One question clients always ask is whether they need audited accounts. For most SMEs, audited financials are not mandatory for the return itself - but they are required if annual revenue crosses the AED 50 million threshold.
How Do You File on EmaraTax?
Filing happens entirely online through the FTA's EmaraTax portal. Here is the process:
- Log in with your UAE Pass credentials
- Go to the Corporate Tax section and select the relevant tax period
- Complete the return - the system pre-populates your taxpayer details and walks you through revenue reconciliation followed by deduction claims
- You can also download a template, fill in the data offline, and upload it through the portal
- Review, submit, and pay any tax due through the same portal
If you have not registered for corporate tax yet, you need to do that first. Registration is done through EmaraTax and gives you your TRN. The FTA set staggered registration deadlines based on your trade licence issuance month, and a late registration attracts an AED 10,000 penalty (Cabinet Decision No. 10 of 2024). That said, there is a waiver: if you file your first return within seven months of your first tax period ending, the late registration penalty is credited back.
What Happens If You File Late?
The penalty for late filing is AED 500 for the first offence and AED 1,000 for each subsequent tax period (FTA, 2025). Even a one-day delay counts.
Unpaid tax attracts 14% annual interest - roughly 1.17% per month - with no cap. The interest keeps accruing until you pay in full. Under the revised penalty framework (Cabinet Decision No. 129 of 2025), which took effect on 14 April 2026, incorrect returns carry a fixed AED 500 penalty for a first violation and AED 2,000 for repeats (PwC, 2025).
The FTA conducted over 93,000 inspection visits in 2024 - a 135% increase on the prior year (Alvarez & Marsal, 2025). Enforcement is ramping up, and first-time filers are not excluded from the audit pool.
What Are the Most Common First-Filing Mistakes?
In our experience working with UAE businesses through their first corporate tax cycle, these errors come up repeatedly:
- Assuming Small Business Relief applies without checking prior-period revenue
- Filing the return but not paying the tax (or vice versa) - both must happen by the deadline
- Using cash-basis figures instead of IFRS-compliant accrual accounting
- Failing to claim allowable deductions because supporting documents were not kept
- Missing the registration deadline and triggering the AED 10,000 penalty before even reaching the return stage
If your bookkeeping has been inconsistent, sorting it out before filing will save you time and reduce the risk of errors that attract FTA scrutiny.
Frequently Asked Questions
Can I file my corporate tax return myself, or do I need an accountant?
You can file directly through EmaraTax. But if you are claiming deductions, dealing with related-party transactions, or unsure about IFRS adjustments, working with a qualified accountant reduces the risk of errors that trigger penalties or audits.
What if my company made a loss - do I still file?
Yes. All tax-resident juridical persons must file regardless of profit or loss. Losses can be carried forward to offset future taxable income, but only if you file the return reporting them.
Does my free zone company need to file a corporate tax return?
Yes. Free zone businesses file annually. If you qualify as a QFZP, your qualifying income is reported at 0%. Non-qualifying income is taxed at 9%. See our free zone corporate tax guide for the full breakdown.
Is the AED 375,000 threshold an exemption?
No. It is a 0% rate band. You still file a return and report all income. The 9% rate applies only to the portion of taxable income above AED 375,000.
When does Small Business Relief expire?
SBR covers tax periods ending on or before 31 December 2026. After that date, businesses currently relying on SBR will need to account for corporate tax at the standard rates. Plan ahead - the transition from zero tax to 9% affects cash flow and pricing.
