UAE Corporate Tax Return Filing Guide 2026: Deadlines, Steps, Penalties

Every company in the UAE must register for Corporate Tax and file a return, even if it owes no tax. Many small business owners only learn this when a penalty notice arrives. This guide explains the deadlines, how to file on EmaraTax, Small Business Relief, and the penalties to avoid. This UAE corporate tax return guide keeps it simple.

The key rules in one table
| Rule | What it means |
|---|---|
| Rate | 0% on taxable income up to AED 375,000; 9% above that |
| Who files | All taxable persons: mainland and free zone companies, and individuals whose business turnover is above AED 1 million |
| Filing deadline | Within 9 months after the end of the tax period |
| Payment deadline | Same as the filing deadline |
| Example | Financial year ending 31 Dec 2025 → file and pay by 30 Sep 2026 |
| Small Business Relief | Revenue up to AED 3 million can elect to be treated as having no taxable income, for tax periods ending by 31 Dec 2029 |
Step 1: Make sure you are registered
Corporate Tax registration is mandatory for every company. Register on EmaraTax, get your Corporate Tax TRN, and note your tax period (usually your financial year). Late registration carries a penalty, so do this first if you have not. See our guide to Corporate Tax registration on EmaraTax.
Step 2: Prepare your figures
- Financial statements for the period (audited if you are a Qualifying Free Zone Person or your revenue is above AED 50 million; otherwise prepared statements are usually enough).
- Accounting profit, then tax adjustments: non-deductible expenses (for example, part of entertainment costs, fines and penalties), exempt income and related-party transactions.
- Records of transactions, assets, liabilities and shareholdings for the period.

Step 3: Decide on Small Business Relief
If your revenue in the tax period and each previous period is AED 3 million or less, you can elect Small Business Relief. You still file a (simplified) return, but you are treated as having no taxable income. Qualifying Free Zone Persons and members of large groups cannot use it. Keep your revenue records, because the FTA can check eligibility.
Step 4: File on EmaraTax
- Log in to EmaraTax and open your taxable person profile.
- Go to Corporate Tax → Returns and open the return for the period.
- Complete the sections: basic information, financial results, adjustments, exemptions and reliefs, and tax computation.
- Upload financial statements where required.
- Review the computed tax, declare and submit.
Step 5: Pay any tax due
Pay through EmaraTax (card, bank transfer or GIBAN) by the same 9-month deadline. A zero-tax return still has to be filed on time.
Penalties to avoid
- Late registration: a fixed administrative penalty (AED 10,000 under the published rules; the FTA has run waiver programmes for first returns filed on time, so check what currently applies).
- Late filing: a monthly penalty that increases the longer the return is late.
- Late payment: a percentage penalty on the unpaid tax for each month it stays unpaid.
- Poor records: separate penalties for not keeping required records.
Check the current penalty amounts on the FTA website, because they have been updated during 2025–2026.
Common mistakes
- Thinking “no profit = no return”. Every taxable person files.
- Confusing the VAT return deadline (28 days) with the Corporate Tax deadline (9 months).
- Free zone companies assuming all income is 0% without checking the qualifying income rules.
- Missing the Small Business Relief election, which must be made in the return.
Frequently asked questions
When is my first Corporate Tax return due?
Nine months after the end of your first tax period. For a calendar year 2025 company, that was 30 September 2026.
Do I need an audit?
Not always. Audited statements are required for Qualifying Free Zone Persons and businesses with revenue above AED 50 million. Many free zones also ask for audits for licence renewal.
Can freelancers be liable?
Yes. A natural person whose business turnover is more than AED 1 million in a calendar year must register and file.
