What Happened — The Problem
A Dubai-based free zone company (FZCO) registered for corporate tax in mid-2024 through the EmaraTax portal. At the time of registration, the FTA's system assigned the first corporate tax period as 01/01/2024 to 31/12/2024. This was the only period available on the portal. The company filed its CT return for this period on time — well before the deadline. Zero revenue, zero tax payable. Everything was compliant.
Months later, without any notification or explanation, the FTA issued a revised Corporate Tax registration certificate that changed the first tax period to 01/01/2023 to 31/12/2023. This newly created period appeared on the EmaraTax portal — backdated by an entire year — and the system automatically applied a late filing penalty of AED 500/month for every month the return for this "new" period was overdue.
By the time the company noticed the change, the penalty had accumulated to AED 6,000 (12 months × AED 500).
The company filed for the only tax period that existed on EmaraTax at the time. There was no option, no button, no interface on the portal to file a return for 2023. The tax period simply didn't exist until the FTA retroactively created it. The penalty was triggered by a system-level change — not by any negligence or delay on the company's part.
This isn't an isolated case. We've seen this happen to multiple businesses — particularly free zone companies that registered for CT in 2024 but had trade licences dating back to 2022 or 2023. The FTA's system sometimes recalculates the first tax period based on the trade licence incorporation date, which can predate the CT registration date.
What We Did — The Fix
The company engaged Fastlane to resolve the issue. We took a two-pronged approach: file the missing return immediately (to stop the penalty clock) and apply for a penalty waiver (to reverse the accumulated AED 6,000).
Step 1: File the CT Return for the New Period — Immediately
Even though the penalty was unjust, the first priority was to stop it from getting worse. The late filing penalty accumulates at AED 500/month. Every day of delay added to the total. We confirmed the revenue for the 2023 period (AED 0 — the company had zero activity), prepared the nil CT return, and filed it on EmaraTax the same day.
✅ CT return for 01/01/2023–31/12/2023 filed successfully. AED 0 taxable income. AED 0 tax payable. FTA confirmation received with reference number. The penalty clock stopped immediately.
Never wait for the waiver outcome before filing the return. The penalty keeps accumulating while you argue. File the return to stop the bleeding, then pursue the waiver separately. These are two independent processes on EmaraTax.
Step 2: Prepare the Declaration Letter
The penalty waiver application on EmaraTax requires a signed declaration letter explaining the circumstances. This is the most important document in the process — it's what the FTA reviewer reads to decide whether to grant or deny the waiver.
Our declaration letter covered these key points:
The original registration certificate showed 01/01/2024–31/12/2024 as the first tax period. The CT return for this period was filed on time and within the prescribed deadline.
No earlier period was available on EmaraTax. At the time of the original filing, there was no option, no link, and no system functionality to submit a return for any period before 2024. The taxpayer had zero ability to file for 2023 because the period didn't exist on the portal.
The revised certificate was issued later by the FTA, changing the first tax period to 01/01/2023–31/12/2023. This revision was made retroactively, and the new period was only activated on the portal after the deadline had already passed.
The non-compliance was caused by the FTA's own system — not by negligence, ignorance, or intent to delay. The taxpayer acted in full compliance with the information available at the time.
The declaration was signed and stamped by the company's authorised signatory and uploaded to EmaraTax as a supporting document.
Step 3: Submit the Waiver Application on EmaraTax
On EmaraTax, we submitted an Application for Waivers with the following details:
| Field | What We Entered |
|---|---|
| Tax Type | Corporate Tax |
| Penalty Reference | [The auto-generated penalty reference number] |
| Penalty Type | CT Late Return Filing Penalty |
| Penalty Amount | AED 6,000 |
| Reason for Waiver | "A general malfunction in the Authority's systems, payment gateways or used telecommunication services, where that was a direct cause for not fulfilling the tax obligations" |
| Detailed Justification | Full explanation of the retroactive period change — original certificate, revised certificate, no portal access for the earlier period |
| Supporting Documents | Signed declaration letter, original CT registration certificate, revised CT registration certificate |
The waiver reason we selected — "general malfunction in the Authority's systems" — was deliberate. The FTA's system retroactively created a tax period and auto-applied a penalty without giving the taxpayer the ability to comply. That is, in essence, a system-level failure that directly caused the non-compliance. This is one of the grounds recognised under Cabinet Decision No. 105 of 2021 for penalty waivers.
The Timeline — From Discovery to Full Reversal
Penalty Discovered
The company noticed an AED 6,000 penalty on their EmaraTax account for "CT Late Return Filing Penalty" for the tax period ending December 2023. The revised CT registration certificate showed a new first tax period that didn't exist before.
Fastlane Engaged — Return Filed Immediately
Client confirmed AED 0 revenue for 2023. Fastlane filed the nil CT return for 01/01/2023–31/12/2023 on EmaraTax within hours. FTA confirmation received. Penalty clock stopped.
Declaration Letter Prepared & Waiver Submitted
Fastlane drafted the declaration letter, client signed and stamped it, and the penalty waiver application was submitted on EmaraTax with full supporting documentation — all on the same day.
FTA Review Period
The FTA reviewed the waiver application. No additional information was requested. Fastlane monitored the EmaraTax transaction history regularly for updates.
Full Penalty Reversed ✓
The FTA processed a "Reversal" transaction on EmaraTax — crediting AED 6,000 back to the account. The penalty was fully waived. Transaction history now shows a net balance of AED 0.
✅ Result: AED 6,000 penalty fully reversed. Zero cost to the client (other than the AED 250 waiver filing fee). All CT returns filed. Account clean. Total time from discovery to reversal: approximately 3 months.

💬 Get Penalty Waiver HelpIs This Happening to You? How to Check
Many businesses don't realise their first tax period has been changed until they see a penalty on their EmaraTax dashboard. Here's how to check:
Step 1: Log into EmaraTax (eservices.tax.gov.ae).
Step 2: Go to your Corporate Tax tile and check the Transaction History. Look for any "CT Late Return Filing Penalty" entries you don't recognise.
Step 3: Download your current CT Registration Certificate from the portal. Compare the first tax period on this certificate with the period you originally filed for.
Step 4: If the first tax period has changed — and you have a penalty for a period that didn't exist when you first registered — you likely have grounds for a waiver.
Step 5: File the CT return for the new period immediately (even if it's nil), then submit a waiver application.
Why This Happens — And Who's Most at Risk
This issue primarily affects businesses that:
Were incorporated before 1 June 2023 (when UAE Corporate Tax came into effect) but registered for CT later in 2024. The FTA's system may recalculate the first tax period based on the incorporation date on the trade licence — which can pull the period back to 2023 or even earlier.
Are free zone companies with trade licences issued in 2022 or early 2023. Free zone licence dates are often earlier than the CT registration date, and the FTA's automated system uses the licence date as the anchor.
Registered through a tax agent who selected a specific first tax period that the FTA later revised. The agent may have correctly entered 2024 based on the rules at the time, but the FTA subsequently adjusted it.
If your company falls into any of these categories, check your EmaraTax account now. Don't wait for a penalty notification — the FTA doesn't always send email alerts for auto-applied penalties.
What Grounds Can You Use for a Penalty Waiver?
Under Cabinet Decision No. 105 of 2021, the FTA may waive administrative penalties in specific circumstances. The most relevant grounds for retroactive tax period changes are:
Ground 1: System malfunction. "A general malfunction in the Authority's systems, payment gateways or used telecommunication services, where that was a direct cause for not fulfilling the tax obligations." This is the ground we used — the system retroactively created a period and applied a penalty without giving the taxpayer the ability to comply.
Ground 2: Circumstances beyond the taxable person's control. The taxpayer acted in full compliance with the information available. The change was made by the FTA, not by the business.
Your declaration letter should clearly connect the facts to one or both of these grounds. Generic statements like "please waive the penalty" will be rejected. The FTA needs a specific, documented explanation of why the non-compliance was not your fault.
What to Include in Your Declaration Letter
Based on this successful case, here's what an effective declaration letter should contain:
1. Your company details — legal name, TRN, and the penalty reference number.
2. The original tax period — as shown on your original CT registration certificate. State clearly that you filed for this period on time.
3. The revised tax period — as shown on the revised certificate. State that this period was not available on the portal at the time of your original filing.
4. The specific facts — no filing option existed, no system access was available, the taxpayer had no ability to comply, the change was made retroactively by the FTA.
5. The corrective action you've taken — confirm the return has now been filed and you are committed to ongoing compliance.
6. The legal basis for the waiver — reference Cabinet Decision No. 105 of 2021 and the specific ground (system malfunction or circumstances beyond control).
7. Signature and stamp — the authorised signatory must sign, and the company stamp must be applied.
What If Your Waiver Is Rejected?
Not all waiver applications are approved on the first attempt. If the FTA rejects yours:
Reconsideration Request: You can submit a formal Reconsideration Request to the FTA within 40 business days of the rejection decision. This is a second review by a different FTA team. Include any additional evidence or clarification that strengthens your case.
Tax Disputes Resolution Committee (TDRC): If the reconsideration is also rejected, you can escalate to the TDRC within 40 business days of the reconsideration decision. The TDRC is an independent body that reviews tax disputes.
