Who must file a corporate tax return?
Every taxable person registered for corporate tax must file a return, including free zone companies and businesses with no tax to pay.
Deadline
The return and any tax due must be submitted within nine months after the end of the tax period. For a calendar-year company, that is 30 September of the following year.
Documents to prepare
- Financial statements for the tax period
- Trial balance and general ledger
- Bank statements and loan details
- Details of related party transactions
- Fixed asset register and depreciation schedule
Steps to file
- Prepare financial statements for the tax period.
- Calculate taxable income, adjusting for non-deductible expenses and reliefs.
- Log in to EmaraTax and open the corporate tax return.
- Enter the figures and upload supporting schedules.
- Submit the return and pay the tax due by the deadline.
Penalties for late filing
The FTA can charge AED 500 per month for the first 12 months of delay and AED 1,000 per month after that, plus penalties on unpaid tax.

Mistakes to avoid when you file corporate tax return UAE
Many problems come from late or incomplete accounts. When you file corporate tax return UAE forms, the return must agree with your financial statements.
- Starting preparation after the deadline is close
- Missing related party and connected person transactions
- Treating non-deductible expenses as deductible
- Ignoring free zone qualifying income tests
- Not keeping supporting documents for seven years
A short review by a consultant before submission can catch these issues and save penalties.
What a good corporate tax return file contains
A complete file makes the return easy to review and easy to defend if the FTA asks questions later. It should show how every figure moved from your accounts to the return.
- Signed financial statements for the tax period
- A taxable income computation with adjustments explained
- Schedules for related party transactions
- Depreciation and fixed asset workings
- Copies of key contracts and agreements
- A copy of the submitted return and payment proof
Keep this file for seven years. A well organised file also saves time in the following year, because most of the work can be updated rather than rebuilt.
