How voluntary disclosure works for all taxes in the UAE

What is voluntary disclosure in the UAE for all taxes?

A voluntary disclosure is a formal notification you submit to the Federal Tax Authority (FTA) when you discover an error or omission in a previously filed tax return or refund application. It applies to every tax administered by the FTA: Value Added Tax (VAT), corporate tax, and excise tax. Filing one corrects your record before the FTA finds the mistake during an audit.

Understanding voluntary disclosure is a core part of staying on top of FTA compliance in the UAE. This article explains who must file, when to file, how penalties work, and what happens after you submit.

Legal basis for voluntary disclosure

The voluntary disclosure mechanism is set out in Federal Decree-Law 17 of 2024 on tax procedures. This law replaced earlier provisions and now governs how taxpayers interact with the FTA across all tax types. The key articles require any taxable person who identifies an error in a filed return to notify the FTA within a specific window.

Which taxes are covered?

The obligation covers every tax the FTA administers:

• VAT, governed by Federal Decree-Law 8 of 2017, with a standard rate of 5% since January 1, 2018.
• Corporate tax, governed by Federal Decree-Law 47 of 2022, at 0% on the first AED 375,000 of taxable income and 9% above that threshold.
• Excise tax, governed by Federal Decree-Law 7 of 2017.

If you hold a Tax Registration Number (TRN) for any of these taxes and you find an error, the voluntary disclosure rules apply to you.

When must you file a voluntary disclosure?

The timing rules differ depending on whether the error increases or decreases your tax liability. Getting the timing right is critical. For a deeper look at deadlines and late-filing risks, see our guide on voluntary disclosure UAE timing.

Errors that increase your liability

If the correction means you owe more tax, you must file the voluntary disclosure before the earlier of:

• 20 business days from the date you became aware of the error.
• The due date of the next tax return for the same tax type.

Errors that decrease your liability

If the correction means you overpaid, the deadline is generally the same, but the penalty exposure is lower because the FTA has not lost revenue.

Threshold for filing

A voluntary disclosure is required when the error results in a difference that exceeds AED 10,000 between the correct tax liability and the amount originally reported. If the difference is AED 10,000 or less, you may correct it in the next regular return instead.

How to file a voluntary disclosure with the FTA

The process is handled through the FTA's EmaraTax portal. Below is a step-by-step overview.

Step 1: Identify and document the error

Gather all supporting documents. These include the original return, the corrected figures, invoices, credit notes, and any internal memos that explain how the error occurred. Clear documentation speeds up FTA review.

Step 2: Calculate the tax impact

Work out the difference between what you reported and what you should have reported. If the net difference exceeds AED 10,000, a voluntary disclosure is mandatory.

Step 3: Log in to EmaraTax and select the correct tax type

Navigate to the voluntary disclosure section under the relevant tax registration (VAT, corporate tax, or excise tax). Each tax type has its own disclosure form.

Step 4: Complete the form

Enter the tax period affected, the original figures, the corrected figures, and a clear explanation of the error. Attach supporting documents.

Step 5: Pay any additional tax due

If the disclosure increases your liability, pay the outstanding amount immediately. Prompt payment reduces penalty exposure.

Step 6: Submit and retain confirmation

Save the submission reference number. The FTA may accept the disclosure, reject it, or request further information.

Penalties related to voluntary disclosure

Cabinet Decision 106 of 2025 sets the penalty framework. Penalties for voluntary disclosure errors range from AED 2,500 to AED 50,000 per violation, depending on the severity and whether the taxpayer acted in good faith.

If you believe a penalty is unjust, you can challenge it. Start with an FTA reconsideration request. If the FTA upholds the penalty, escalate to the UAE Tax Dispute Resolution Committee. Further appeals follow UAE tax court procedures.

Can penalties be reduced or waived?

Yes. The FTA has discretion to reduce penalties in certain cases. Grounds for reduction include first-time violations, voluntary correction before an audit notification, and financial hardship. Read more about penalty waiver grounds in the UAE. If you cannot pay a penalty in full, you may also apply for a penalty instalment arrangement.

Common errors that trigger voluntary disclosures

Across all three tax types, certain mistakes appear repeatedly.

VAT errors

• Claiming input tax on non-deductible expenses (entertainment, personal use).
• Applying the wrong VAT rate (0% instead of 5% or vice versa).
• Failing to account for deemed supplies on assets transferred outside the business.
• Incorrect treatment of imports under the reverse charge mechanism.

Corporate tax errors

• Misclassifying exempt income, such as qualifying dividends.
• Errors in transfer pricing adjustments between related parties.
• Incorrect application of small business relief for revenue up to AED 3M (available through 2026).
• Omitting foreign branch income that should be included.

Excise tax errors

• Incorrect classification of excisable goods (e.g., sweetened beverages vs. carbonated drinks).
• Errors in stock declarations.
• Failure to account for goods released from a designated zone.

What happens after you submit

The FTA reviews your voluntary disclosure and may take one of three actions:

1. Accept the disclosure. Your tax record is updated. Any additional tax and applicable penalties are confirmed.
2. Reject the disclosure. The FTA may disagree with your corrected figures. You will receive a notification explaining why.
3. Request more information. The FTA may ask for additional documents or clarification before making a decision.

If the FTA rejects your disclosure or you disagree with the resulting assessment, the dispute resolution path begins with a reconsideration request, then moves to the Tax Dispute Resolution Committee, and finally to the courts.

Voluntary disclosure vs. amended return

These two concepts are sometimes confused. An amended return replaces a previously filed return within the normal filing window. A voluntary disclosure is filed after the return deadline has passed and the original return is already final. If you catch an error before the filing deadline, amend the return directly. If the deadline has passed, use the voluntary disclosure process.

Practical checklist for UAE businesses

• Review each tax return before submission using a four-eyes principle (two people check).
• Reconcile VAT returns to your accounting system every period.
• Set a calendar reminder 15 business days after discovering any error to ensure you file within the 20-business-day window.
• Keep a log of all voluntary disclosures filed, including reference numbers and FTA responses.
• Consult a tax adviser for complex errors, especially those involving transfer pricing or cross-border transactions.
• Monitor your FTA compliance obligations regularly to catch issues early.
