Error in UAE Corporate Tax Return? What Should You Do?
Error in UAE Corporate Tax Return? What Should You Do?
Discovering an error after submitting your UAE Corporate Tax return can be worrying. You may have omitted income, claimed an expense incorrectly, selected the wrong tax treatment or entered figures that do not match your financial statements.
The most important thing is not to ignore the error or wait for the Federal Tax Authority to identify it. UAE tax procedures allow businesses to correct mistakes, but the appropriate method depends on the nature of the error, the amount of tax involved and whether the FTA has already notified the business of a tax audit.
Taking prompt action can reduce penalties, protect the company’s compliance position and prevent a relatively small mistake from becoming a larger tax problem.
Can a Filed Corporate Tax Return Be Corrected?
Yes. A submitted Corporate Tax return can be corrected.
However, a business generally cannot simply delete the filed return and submit a replacement. Depending on the circumstances, the correction may need to be made through a Voluntary Disclosure on the EmaraTax platform or through another correction method permitted by the applicable tax procedures.
A Voluntary Disclosure is a formal submission informing the FTA that information previously reported in a tax return, tax assessment or refund application was incorrect.
Before submitting anything, the company should determine:
What information was reported incorrectly?
What caused the error?
Does the error increase or decrease Corporate Tax payable?
What is the value of the tax difference?
When did the company become aware of the error?
Has the FTA issued a tax audit notification?
What supporting records are available?
These questions determine the appropriate correction procedure and potential penalty exposure.
Step One: Identify the Exact Error
I Filed My Corporate Tax Return but Discovered an Error—What Should I Do? Begin by comparing the submitted Corporate Tax return with the company’s final accounting records, financial statements, tax calculations and supporting schedules.
Common Corporate Tax return errors include:
Failing to report certain business income
Entering incorrect revenue or expense figures
Claiming non-deductible expenses
Incorrectly treating entertainment expenses
Applying the wrong treatment to related-party transactions
Failing to make required transfer-pricing adjustments
Incorrectly calculating taxable gains or losses
Claiming Small Business Relief without meeting all the conditions
Incorrectly classifying Free Zone income
Applying the 0% Free Zone Corporate Tax rate incorrectly
Omitting foreign income or foreign tax credits
Incorrectly carrying forward tax losses
Using figures that do not agree with the financial statements
Entering information under the wrong section of the return
The company should not correct one figure without checking its effect on the rest of the return. One accounting adjustment may change taxable income, tax losses, related-party disclosures, relief eligibility and the final Corporate Tax payable.
Step Two: Calculate the Tax Difference
The next step is determining whether the error caused the company to pay too little tax, too much tax or the correct amount despite inaccurate information.
The error resulted in underpaid tax exceeding AED 10,000
If the error resulted in an understatement of tax exceeding AED 10,000, the business will generally be required to submit a Voluntary Disclosure within 20 business days from the date it became aware of the error.
The company should document the discovery date because this date may determine whether the submission was made within the required period.
The tax difference is AED 10,000 or less
Where the underpaid tax is AED 10,000 or less, the error may generally be corrected through the next eligible Tax Return. If there is no future return through which the correction can be made, a Voluntary Disclosure may be required within 20 business days of discovering the error.
Because Corporate Tax returns are normally annual, businesses should not automatically assume that they can wait until the following year. The circumstances and the correction option available on EmaraTax should be reviewed promptly.
The company paid too much Corporate Tax
An error may result in the company reporting more taxable income or paying more Corporate Tax than required. For example, the business may have omitted a deductible expense, failed to claim an available relief or applied an incorrect adjustment.
The company should assess whether a Voluntary Disclosure should be submitted and whether the resulting credit should remain on its tax account or be claimed as a refund.
Current UAE tax procedures include time limits for claiming tax credit balances. Therefore, overpaid tax should not be left unreviewed indefinitely.
The error does not change the tax payable
Some errors affect the information reported without changing the final Corporate Tax payable. Examples may include an incorrect classification, incomplete disclosure or information entered in the wrong field.
Following the amendments effective in 2026, a Voluntary Disclosure is not automatically required for every error that produces no difference in tax payable. Nevertheless, the error should still be reviewed to determine whether the FTA requires it to be corrected through a specific procedure.
Step Three: Prepare Supporting Documents
A correction should be supported by a clear and complete file. This may include:
The originally submitted Corporate Tax return
Corrected tax computation
Final trial balance
Financial statements
General ledger
Bank reconciliations
Sales and purchase records
Fixed-asset register
Expense schedules
Related-party transaction details
Supporting invoices and contracts
Free Zone income analysis
Tax-loss schedules
A reconciliation between the original and corrected figures
A written explanation of the error and how it occurred
The explanation should clearly show the original treatment, the corrected treatment and its effect on Corporate Tax payable. A vague explanation could lead to questions or delays from the FTA.
Step Four: Submit the Correction Through EmaraTax
Where a Voluntary Disclosure is required, it should be submitted through the company’s EmaraTax account by an authorised signatory, legal representative or authorised tax agent.
The company should carefully review the disclosure before submission. Submitting another incorrect calculation may create additional complications and weaken the reliability of the company’s tax records.
After submission, retain the acknowledgement, payment confirmation, corrected calculation and all supporting documents in the Corporate Tax compliance file.
Step Five: Pay Any Additional Corporate Tax Promptly
If the correction creates additional Corporate Tax payable, the business should arrange payment without unnecessary delay.
The penalty framework effective from 14 April 2026 introduced a monthly penalty generally calculated at 1% of the tax difference where a Voluntary Disclosure is submitted before an FTA tax audit notification. If the required disclosure is not made before an audit notification, an additional fixed penalty of 15% may apply, together with the applicable monthly penalty.
Late-payment consequences may also arise on unpaid tax. The exact calculation depends on the circumstances and relevant dates, so the company should calculate its total exposure before making the submission.
Correcting an error before the FTA begins an audit is generally more favourable than waiting for the Authority to discover it.
Mistakes to Avoid After Discovering an Error
Businesses should avoid:
Ignoring the error because the amount appears small
Changing the accounting records without documenting the adjustment
Waiting for the FTA to contact the company
Submitting a Voluntary Disclosure before completing a full tax review
Paying an estimated amount without confirming the correct tax liability
Correcting only the tax return while leaving the financial statements unchanged
Claiming Free Zone treatment without reviewing all qualifying conditions
Deleting emails or documents showing when the error was discovered
Assuming an accountant’s mistake removes the company’s responsibility
The Taxable Person remains responsible for the accuracy of its Corporate Tax return, even where an employee, accountant or external consultant prepared the submission.

Frequently Asked Questions
Should I wait for the FTA to identify the mistake?
No. Waiting may increase the company’s penalty exposure, particularly if the FTA issues a tax audit notification before the error is corrected.
Does every mistake require a Voluntary Disclosure?
Not necessarily. The required procedure depends on the tax difference, the nature of the error and whether another eligible return is available for correction.
What if the mistake was made by my accountant?
The company remains responsible for the accuracy of its tax return. However, the accountant’s records and explanation may help establish how the error occurred.
Can I correct more than one error in the same review?
Yes. Before submitting a correction, the entire return should be reviewed so that all identified errors and their combined tax effect are properly addressed.
Can the correction result in a Corporate Tax refund?
Potentially. If the original return overstated the company’s liability, the correction may create a credit balance or refund entitlement, subject to the applicable procedures and time limits.
Discovered an Error in Your Corporate Tax Return?
Do not wait until the FTA contacts your company. An early professional review can determine the correct action, calculate the financial impact and help reduce further compliance exposure.
