To amend your Corporate Tax registration on EmaraTax: log in at services.tax.gov.ae → navigate to Corporate Tax → select Edit Registration → update the required fields → upload supporting documents → submit. Most amendments are processed within 20 working days. There is no fee for amendments. Critically: UAE CT Law requires you to notify the FTA of any change to your registration details within 20 business days of the change — failure to do so can attract an administrative penalty of AED 10,000 under Cabinet Decision No. 75 of 2023.
Businesses in the UAE are required to keep their Corporate Tax (CT) registration details current on the EmaraTax portal at all times. Whether your company has changed its name, relocated its registered address, updated its financial year-end, brought on new shareholders, or changed its authorised signatory — the Federal Tax Authority (FTA) must be notified promptly.
This is not merely good practice. Under UAE Corporate Tax Law (Federal Decree-Law No. 47 of 2022), registered taxable persons are legally obligated to update their registration within 20 business days of any change. Missing this window can trigger penalties. This guide walks you through every step of the amendment process, tells you which documents to prepare for each change type, and highlights what happens if you delay.
Under UAE Corporate Tax Law, you must notify the FTA of changes within 20 business days of the change occurring. The administrative penalty for non-compliance is AED 10,000 per Cabinet Decision No. 75 of 2023. If you have changed anything about your business — name, address, ownership, activity — act now.
When Must You Amend Your Corporate Tax Registration?
Any material change to your business information that was submitted during CT registration triggers a mandatory update obligation. Common events that require an amendment:
| Change Event | Amendment Required? | Deadline to Notify FTA | Priority |
|---|---|---|---|
| Business / legal name change | ✔ Yes | Within 20 business days | High |
| Registered address change (UAE) | ✔ Yes | Within 20 business days | Medium |
| Change of authorised signatory | ✔ Yes | Within 20 business days | High |
| Change in ownership / shareholders | ✔ Yes | Within 20 business days | High |
| Change of financial year-end | ✔ Yes (FTA approval needed) | Before the new financial year starts | High |
| Business activity / ISIC code change | ✔ Yes | Within 20 business days | Medium |
| Contact details (email, phone) | ✔ Yes | Within 20 business days | Low |
| Trade licence renewal (new expiry date) | ✔ Update documents | Upon renewal | Medium |
| Bank account details | ✔ Yes (for refund purposes) | Within 20 business days | Medium |
| Entering / exiting a Tax Group | ✔ Separate application | Per FTA Tax Group rules | High |
Processing Times — What to Expect
The FTA may request additional documents or clarification during review. Monitor your EmaraTax inbox and the email address registered with your account — the FTA sends all correspondence there. Failing to respond to an FTA query will stall your application and does not pause your penalty exposure clock.
Documents Required — By Amendment Type
Uploading the wrong or incomplete documents is the most common reason amendments are rejected. Prepare these before you start:
- New trade licence (clearly showing updated name)
- Memorandum of Association (updated, attested)
- Certificate of name change from DED / free zone authority
- Emirates ID of authorised signatory
- New trade licence showing updated address
- Tenancy contract / EJARI (Dubai) or equivalent
- Utility bill (gas/electricity/water) at new address
- Emirates ID of authorised signatory
- Emirates ID of new authorised signatory (both sides)
- Passport copy of new signatory
- Board resolution / POA authorising the new signatory
- Updated trade licence (if name appears on it)
- Updated Memorandum of Association (attested)
- Updated shareholder register
- Emirates IDs of all new shareholders
- Updated trade licence reflecting new ownership
- Share transfer agreement (if applicable)
- Board resolution approving the change in financial year
- Written justification / business reason for the change
- Updated trade licence
- Note: FTA approval is required — not auto-approved
- Updated trade licence showing new activity
- Updated Memorandum of Association (if objects clause changed)
- New ISIC code (confirm with your accountant or FTA)
- Any regulatory approvals for the new activity (if applicable)
All uploaded documents must be legible, in colour, and in PDF or JPG format. Arabic documents must be accompanied by a certified English translation. Scanned images below 200 DPI are frequently rejected. Ensure trade licences are not expired at the time of submission.
Step-by-Step: How to Amend CT Registration on EmaraTax (2026)
-
Log In to the EmaraTax Portal
Navigate to services.tax.gov.ae and sign in with your UAE Pass or EmaraTax credentials. Use the same login that was used to originally register for Corporate Tax. If you have forgotten your credentials, use the portal’s password reset function or contact the FTA helpline on 600 599 994.
-
Open the Corporate Tax Dashboard
From the main dashboard, locate the Corporate Tax tile and click to expand your CT account. You will see your Tax Registration Number (TRN), current registration status, and your filing history. If you manage multiple entities, ensure you have selected the correct entity before proceeding.
-
Select “Edit Registration”
Within the Corporate Tax section, find and click the “Edit Registration” or “Amend Registration” button. This opens the amendment form pre-populated with your existing registration data. Only the fields you need to change will be editable — historical data is read-only.
-
Update the Required Fields
Carefully update only the fields that have changed. Common editable sections include: Entity Details (name, address, contact), Financial Period, Business Activity, and Authorised Signatory. Do not alter any field that has not changed — unnecessary edits can trigger additional FTA review.
-
Upload Supporting Documents
For each field you change, the portal will prompt you to upload the corresponding document. Refer to the document checklist above. Ensure files are under the portal’s size limit (typically 5MB per file) and in the accepted formats (PDF, JPG, PNG). Label your files clearly before upload — for example: “Trade_Licence_2026_New_Address.pdf”.
-
Review All Changes Before Submitting
The portal will display a summary screen showing all amended fields alongside the original values. Review this carefully. Pay particular attention to: TRN number (must not change), tax period dates, and signatory details. Errors submitted to the FTA can delay processing by weeks.
-
Submit and Note Your Reference Number
Click “Submit” to send the amendment request to the FTA. The portal will generate a unique reference number — save or screenshot this immediately. You will need it to track your application status or follow up with the FTA if there is a delay.
-
Track Your Application Status
Return to your EmaraTax dashboard to monitor the status of your amendment under the “My Applications” or “Pending Requests” section. Status updates are also sent by email to your registered address. If the FTA marks the application as “Additional Information Required”, respond promptly — the 20-working-day clock continues regardless.
Penalties for Failing to Amend Your CT Registration
Cabinet Decision No. 75 of 2023 on Administrative Penalties sets a fixed penalty of AED 10,000 for failing to notify the FTA of changes to registration information within the legally mandated 20 business days. This penalty applies per instance and is separate from any other penalties that may arise from incorrect CT returns filed using outdated registration data.
| Violation | Penalty (AED) | Legal Basis |
|---|---|---|
| Failure to notify FTA of registration changes within 20 business days | 10,000 | Cabinet Decision No. 75 of 2023 |
| Providing incorrect information in a CT return (using outdated registration data) | Up to 500% of unpaid tax | UAE CT Law — Article 75 |
| Failure to maintain updated records / documents | 10,000–50,000 | Cabinet Decision No. 75 of 2023 |
| Failure to respond to FTA information request | 10,000 (first instance) / 50,000 (repeat) | Cabinet Decision No. 75 of 2023 |
Beyond financial penalties, operating with outdated FTA records can cause your Tax Clearance Certificate applications to be rejected, delay VAT refunds, and complicate your annual Corporate Tax Return filings. The cost of prompt amendment is zero. The cost of delay can be significant.
Common Reasons Amendments Are Rejected (and How to Fix Them)
| Rejection Reason | Why It Happens | Fix |
|---|---|---|
| Expired trade licence uploaded | Trade licence expired before submission date | Renew trade licence first; then resubmit |
| Document not in colour / illegible | Black-and-white scans or low-resolution images | Rescan at ≥200 DPI in colour; export as PDF |
| Arabic document with no translation | FTA requires certified English translation for Arabic-only documents | Obtain certified translation from licensed translator; upload both |
| Board resolution missing required details | Resolution does not explicitly name the new signatory or state the authority granted | Re-issue resolution with full name, Emirates ID number, and scope of authority |
| Wrong entity selected on portal | User manages multiple entities; amendment applied to wrong TRN | Cancel the incorrect submission; start fresh on the correct entity |
| Address on document doesn’t match amendment | Tenancy contract shows a different unit/floor from what was entered | Ensure the exact address in the form matches the tenancy contract to the letter |
| Financial year-end change not supported by documentation | No board resolution; no business reason provided | Include a formal board resolution and a written justification letter on company letterhead |

Frequently Asked Questions
No. The FTA does not currently charge any fee for amending your Corporate Tax registration details. However, failing to amend within the legally required 20 business days can result in an administrative penalty of AED 10,000 per Cabinet Decision No. 75 of 2023. So while the process itself is free, delaying it is not.
Simple amendments — such as contact information or address updates with clean documentation — are typically processed within 5 to 10 working days. More complex amendments involving ownership changes, financial year-end adjustments, or business activity reclassification can take 20 or more working days. The FTA may also issue an “Additional Information Required” notice that pauses the review clock until you respond.
Yes, but a financial year-end change is not automatic — it requires FTA approval. You must submit a board resolution approving the change, a written business justification on company letterhead, and your updated trade licence. The FTA has discretion to approve or reject the request. Ideally, submit this request before your current financial year begins. Seek professional advice before initiating this amendment, as it affects your Corporate Tax return filing deadlines.
The FTA will notify you via email and through the EmaraTax portal, citing specific reasons for rejection. Common reasons include expired documents, missing translations, or mismatched information. Address every point raised in the rejection notice before resubmitting. If you disagree with the rejection, you can file a formal reconsideration request through the EmaraTax dispute resolution module within 40 business days.
Yes. VAT and Corporate Tax are separate registrations on EmaraTax, even if your TRN is shared. An address change must be updated in both the VAT registration and the Corporate Tax registration sections of the portal. The amendment process is similar for both, but each requires its own submission and FTA approval. The same 20-business-day notification deadline applies to both.
Yes. Qualifying Free Zone Persons (QFZPs) registered for Corporate Tax can amend their registration on EmaraTax using the same process. If a change affects your QFZP status — for example, a change in business activity that may cause you to fail the qualifying income test — you should seek professional advice before submitting the amendment, as it could affect your 0% CT rate eligibility.
Tax Group amendments on EmaraTax are handled through the Representative Member’s account. If a subsidiary’s details change, the Representative Member must update the Tax Group registration. Additions or removals of Tax Group members require a separate application via EmaraTax, not just an amendment form — contact a qualified UAE CT advisor to ensure the correct procedure is followed to avoid affecting the group’s consolidated filing.
Simple amendments — such as updating a phone number or email address — can be done without professional help if you are confident navigating the EmaraTax portal. However, for complex changes (financial year-end, ownership restructuring, business activity changes, or Tax Group adjustments), it is strongly advisable to engage a qualified UAE CT advisor. Errors in these amendments can affect your tax returns, penalty exposure, and QFZP status. ProTax handles EmaraTax amendments as part of our AED 750/month compliance package.
