Your First Corporate Tax Return, Step by Step
Filing your first UAE corporate tax return means five things in sequence: close your books and prepare IFRS financial statements for the tax period, compute taxable income by applying book-to-tax adjustments, apply any reliefs or elections such as Small Business Relief or free-zone qualifying-income treatment, submit the return through the FTA's EmaraTax portal, and pay any tax due - by the same deadline, since there is no separate, later payment window. The standard deadline is nine months after your financial year-end, but filing within seven months of your first tax period end secures the AED 10,000 late-registration penalty waiver where it applies. For a 31 December 2025 year-end, that is 31 July 2026 for the waiver and 30 September 2026 as the statutory deadline. Every registered taxable person files, even with a loss or nil revenue.

Get the numbers right before you touch EmaraTax
The portal itself takes hours once the numbers are correct; almost all of the real work happens before you log in. Rushing the preparation stage to save time on the portal is where most first-time filing problems start.
- Finalise financial statements for the tax period under the correct IFRS basis.
- Compute taxable income by applying book-to-tax adjustments to accounting profit.
- Decide on and apply any elections or reliefs inside the return itself.
- Reconcile every return figure back to your trial balance and general ledger.
- Prepare related-party and connected-person disclosure schedules where thresholds are met.
Submit and settle on EmaraTax
Filing and payment sit on a single deadline, not two separate events - submitting the return does not mean the obligation is met until the tax due has also been paid.
- Log in to EmaraTax with UAE PASS and open the corporate tax return.
- Enter figures, disclosures and elections carefully - errors invite closer FTA scrutiny.
- Submit before the deadline, ideally inside the seven-month waiver window.
- Pay the liability via GIBAN bank transfer or card by the same date.
- Download and keep the EmaraTax acknowledgement as proof of on-time filing.
Your first-filing calendar
Two dates matter for most first-time filers with a 31 December 2025 year-end, and confusing them is one of the most expensive mistakes on this list.
- 31 July 2026: file by this date to secure the AED 10,000 penalty waiver.
- 30 September 2026: the statutory filing and payment deadline, nine months after year-end.
- Filing between 1 August and 30 September meets the law but forfeits the waiver.
- Filing after 30 September triggers late-filing penalties of AED 500 per month for the first 12 months, plus a 14% per annum late-payment penalty on unpaid tax.
What trips up first-time filers
The same handful of mistakes account for most of the late or incorrect first returns Exiloz reviews, and every one of them is avoidable with earlier preparation.
- Leaving bookkeeping clean-up until the weeks before the deadline.
- Treating the return as complete once submitted, without confirming payment has cleared.
- Assuming a loss-making or free-zone business does not need to file at all.
- Trying to add a relief election after the return has already been submitted.

Frequently Asked Questions
For first-time corporate tax filers working through EmaraTax ahead of the 2026 deadlines, and anyone unsure which of the two key dates applies to them.
When is my first return due?
Nine months after your financial year-end - for example, 30 September 2026 for a 31 December 2025 year-end - or within seven months of your first tax period end if you want to secure the AED 10,000 late-registration penalty waiver.
Do I file if I made a loss?
Yes. Every registered taxable person must file an annual corporate tax return, even with a loss, nil revenue, or after electing Small Business Relief. The filing obligation is separate from whether any tax is actually owed.
When do I pay the tax?
By the same filing deadline - there is no separate, later payment window. Payment is made via a GIBAN bank transfer or card through EmaraTax, and the funds need to arrive by the deadline, not just the return submission.
What information does the EmaraTax return actually ask for?
Financial statement figures, the book-to-tax adjustments behind your taxable income calculation, any relief or election you are claiming, and disclosures such as related-party transactions where applicable. Every figure should reconcile back to your underlying accounting records.
Can I amend a return after submitting it?
Corrections to an already-submitted return are made through a voluntary disclosure rather than simply re-editing the filing, which is why getting the figures right before submission matters more than fixing them afterward.
What happens if I miss the 30 September deadline?
Late-filing penalties begin accruing monthly from the day after the deadline, and any unpaid tax accrues a separate late-payment penalty. Missing the deadline can also mean losing the seven-month waiver if it had not already been secured.
Do I need an accountant to file, or can I do it myself?
Nothing legally requires you to use an advisor, but the return depends on IFRS financial statements, correct adjustments, and disclosures most first-time filers have never prepared before - which is why most businesses bring in support for at least the first cycle.
Can Exiloz file the first return for me?
Yes. Exiloz prepares your financial statements, computes taxable income and any reliefs, completes the EmaraTax submission, and confirms payment - handling the first return end to end so nothing is missed.
What is my "first tax period" if my company only started trading partway through the year?
Your first tax period runs from the date the company became a taxable person (often incorporation or licence issue date) to the end of its first full or short financial year, as set on registration. A short first period is common for companies incorporated mid-year and still carries its own nine-month filing deadline and, separately, its own seven-month waiver window - confirm the exact dates on registration rather than assuming a full 12-month period.
Does a short first tax period change how the calculation or reliefs work?
The 0%/9% bands and elections such as Small Business Relief still apply to a short period in the same way, but the revenue thresholds behind some reliefs are generally assessed against the actual period, not annualised - so confirm with your adviser how a short first period affects any threshold-based relief before you file.
