How to deregistration for Corporate Tax in UAE

Business cycles are real. Companies close, merge, or restructure. When that happens, you already have a long to-do list. The last thing you need is a surprise penalty after you think you are “done.” Many owners assume cancelling the trade licence is enough. But the ground reality is it is not. Corporate tax has its own final step with the Federal Tax Authority (FTA). If your Corporate Tax status stays “Active,” the FTA can still expect filings, updates, and responses.

If you have ever handled VAT return filing in Dubai, you know the rule: nothing is finished until the portal agrees it is finished. Corporate tax works the same way. Deregistration Corporate Tax is the final handshake. It closes your corporate tax registration properly, so you can exit with a clean slate.

Apply within 3 months of cessation, file the final return, clear all dues, then submit the request on EmaraTax with proof.

What is Deregistration Corporate Tax?

Deregistration Corporate Tax is the formal process of ending your corporate tax registration with the FTA. It is how you deactivate the tax profile linked to your Tax Registration Number (TRN) for Corporate Tax. In simple terms, it tells the FTA: “This business has ceased, and the file is closed.”

Think of it like cancelling a phone contract. If you stop using the phone but never cancel, the bills keep coming. With corporate tax, the “Active” status is the same trap. As long as the system shows you as active, the FTA can still expect compliance steps.

That is why deregistration corporate tax is not a nice-to-have. It is the official finish line when a business activity ends.

When Do You Need to Deregister? (The Triggers)

You usually need to apply for deregistration when the company, or the business activity, has truly ceased. The Corporate Tax Law ties tax deregistration to cessation of business activity, including cases like liquidation or dissolution.

Here are the most common triggers:

• Scenario A: Cessation of Business
  You are closing permanently, liquidating, or dissolving the entity.
• Scenario B: Mergers & Acquisitions
  Your company is merged into another, and the old legal entity disappears.
• Scenario C: Licence Expiry and Exit
  You let the trade licence lapse and you are leaving the market for good.

Now the key distinction: Dormant vs closed. Dormant means operations are paused, but the entity still exists. Closed means the activity has ceased and you are ending the entity, or ending the taxable activity permanently.

Here is the practical rule: if you are pausing but keeping the licence, do not rush into tax deregistration. You may still have filing duties until the FTA accepts deregistration, and a “nil” return may still be required depending on your facts and filing obligations. If you are truly closing, deregistration is the clean way to stop future expectations.

The “3-Month Rule” & Why Speed Matters

The most important rule is the deadline. A juridical person must submit a Tax Deregistration application within 3 months of cessation, dissolution, liquidation, or when the entity ceases to exist.

Missing the timeline can cost you. Under the UAE administrative penalties framework for corporate tax, failing to submit the deregistration application within the specified timeframe triggers a penalty of AED 1,000 for late submission, and the same amount monthly, up to AED 10,000. 

That is a wasteful expense. It is also 100% avoidable.

The Prerequisites: What You Must Do Before Applying

You cannot simply press a “delete” button. The FTA expects your Corporate Tax account to be clean before it approves deregistration.

Start with the legal rule. The Corporate Tax Law says a person with a TRN must file a deregistration application when there is a cessation of business activity (including liquidation or dissolution), in the form and timeline the Authority prescribes.

Then comes the “clean slate” requirement. You should be ready for three things before you apply:

1. File the final Corporate Tax return for the tax period up to the cessation date.
2. Clear outstanding balances, including any corporate tax payable and any administrative penalties due.
3. Prepare for review. The FTA may request additional information before it completes the application. When that happens, delays usually come from missing documents or mismatched dates.

This is where many businesses get stuck. They submit tax deregistration while there are open filings, unpaid penalties, or unclear proof. The result is a longer timeline, more back-and-forth, and higher risk of missing the 3-month rule.

Step-by-Step: How to Process Deregistration on EmaraTax

The application is done through the EmaraTax platform using the FTA’s deregistration Corporate Tax service. The FTA lists the service as free of charge, with an estimated 20 minutes to submit the application.

A simple workflow looks like this:

1. Log in to EmaraTax and open your Corporate Tax dashboard.
2. Choose the deregistration Corporate Tax service action.
3. Enter the reason for deregistration and the date of cessation.
4. Upload proof documents that support the cessation event.
5. Review your details, then submit.

Approval is not instant. The FTA estimates 30 business days to complete the application from the date it receives a completed submission. If the FTA asks for extra information, it can take additional time, and it may take a further 30 business days after you re-submit the updated application.

If you want the process to go smoothly, treat the cessation date like a “source of truth,” and make sure every document supports it.

Required Documents Checklist

Keep the proof ready before you apply. It helps you avoid rejection loops and delays.

• Trade licence cancellation certificate (or equivalent closure proof)
• Liquidation report or dissolution paperwork (if applicable)
• Final-period financial statements or closing accounts
• Any supporting letters or documents the authority requests for your case

Your exact list can vary, but the principle does not change: your documents must prove the cessation event and align with the date you declare in the application.

In a Nutshell

Closing a business is hard enough. Tax portals should not add more stress. The safest plan is simple: apply within 3 months, clear the account, file the final return, then submit your deregistration Corporate Tax request with proof.
