Key takeaways
- An error that changes tax due by more than AED 10,000 must be corrected by voluntary disclosure; smaller errors can go in the next return.
- The disclosure is due within 20 business days of discovering the error.
- From 14 April 2026, Cabinet Decision No. 129 of 2025 replaced the old percentage penalties with a 1% per month charge before an audit notice and a fixed 15% after one.
- Disclosing before the FTA contacts you remains far cheaper than waiting.
Every VAT-registered business will eventually find a mistake in a submitted return: a missed reverse charge, an invoice booked in the wrong quarter, input VAT claimed on blocked expenses. The question is not whether to correct it but how. The UAE’s voluntary disclosure (VD) mechanism exists for exactly this, and the 2026 penalty reform has made prompt disclosure more attractive than ever.
What is a VAT voluntary disclosure?
A voluntary disclosure is a formal notification to the Federal Tax Authority, filed on EmaraTax, that a previously submitted return or refund application was wrong. It identifies the period, explains the error and states the correct figures. Where tax is underpaid, the business pays the difference.
When is a voluntary disclosure mandatory?
- The error results in a tax difference above AED 10,000: a voluntary disclosure is required.
- The difference is AED 10,000 or less: the business can correct it in the return for the period in which the error was discovered.
- The error results in tax overpaid: a disclosure can be used to recover it.
The disclosure must be submitted within 20 business days of the business becoming aware of the error.
VAT penalties after 14 April 2026
Cabinet Decision No. 129 of 2025 introduced a unified penalty framework for VAT and excise tax, effective 14 April 2026:
| Situation | Penalty |
|---|---|
| Voluntary disclosure before an FTA audit notification | 1% per month on the tax difference, until the disclosure is submitted |
| Disclosure after an FTA audit notification | Additional fixed 15% of the tax difference (reduced from 50%) |
| Late payment of tax | 14% per annum, accrued monthly |
| Incorrect tax return | AED 500 first time; AED 2,000 for a repeat — none if corrected before the due date or by a disclosure with no tax impact |
The practical message: the longer an error sits, the more the monthly charge grows, and an FTA audit notice adds a fixed 15% on top.
Common errors that lead to disclosures
- Missing reverse charge on imported services or goods.
- Input VAT claimed on blocked items such as entertainment or employee personal expenses.
- Zero-rating exports without proof of export.
- Tax invoices dated in the wrong period, or credit notes not reflected.
- Incorrect treatment of real estate, designated zone or financial service supplies.
How to file a VAT voluntary disclosure
- Quantify the error for every affected period, not just the one you noticed.
- Check for patterns. One error usually means a process problem; review neighbouring periods.
- Prepare the disclosure on EmaraTax with a clear explanation and supporting schedules.
- Pay the tax difference promptly to stop late payment penalties accruing.
- Fix the process so the error does not repeat in the next return.
Our VAT voluntary disclosure service handles the quantification and filing, and a VAT health check is the fastest way to find errors before the FTA does. If an audit notice has already arrived, see FTA audit representation.
Frequently asked questions
Is there a deadline to file a VAT voluntary disclosure?
Yes — within 20 business days of discovering the error.
Can I correct a small VAT error in my next return instead?
Yes, if the tax difference is AED 10,000 or less.
Do penalties apply if I disclose voluntarily?
Under the 2026 framework, a 1% per month charge applies until the disclosure is made. It is significantly lower than penalties applied after an FTA audit notification.
Can I use a voluntary disclosure to claim back overpaid VAT?
Yes. Disclosures can correct errors in your favour as well as against you.
