How to File a Voluntary Disclosure
A voluntary disclosure (VDF, filed as Form 211) is the formal way to correct an error in a filed VAT or corporate tax return on EmaraTax. It carries two penalties: a fixed amount (AED 1,000 for a first disclosure, AED 2,000 for a repeat within 24 months) and a percentage penalty on the tax difference that grows the longer the error goes unreported — from around 5% if disclosed within a year of the original due date, up to 40% after four years. Errors of AED 10,000 or less can usually be corrected in the next return instead, with no separate disclosure needed. Quantify the error, gather support, file the VDF before the FTA finds it or opens an audit of that period, and settle promptly — timing, more than the error itself, decides the final cost.

Quantify the error first
A disclosure is only as sound as the numbers behind it, so the first task is arithmetic, not paperwork. You need the affected return and period identified precisely, the correct figure recalculated, and the resulting tax difference isolated before anything is submitted. Skipping this step and disclosing an estimate is a common way a straightforward correction turns into a drawn-out FTA query.
- Identify the affected return and tax period precisely — the disclosure is filed against a specific filing, not the business generally.
- Recalculate the correct figure and isolate exactly how much tax was underpaid or overpaid.
- Gather invoices, ledgers and workings that justify the corrected numbers before filing.
- Check whether the same error repeats in neighbouring periods — it usually does, and the FTA will check.
- Confirm whether the error clears the AED 10,000 threshold that decides between a next-return correction and a formal disclosure.
- Rule out an open FTA audit of the same period before filing, since a disclosure made mid-audit loses most of its benefit.
Submit and stop the clock
Prompt settlement is what actually limits the final cost, because the percentage penalty band is fixed at the point of disclosure but interest and administrative exposure keep building until payment clears. Filing the VDF on EmaraTax is a structured process — the specific return is selected, the corrected figures and supporting evidence are attached, and the disclosure is submitted for FTA review before payment is finalised.
- Submit the voluntary disclosure for the specific return and period through EmaraTax, not as a general notification.
- Attach the supporting evidence — invoices, ledgers and a clear explanation of what went wrong.
- Pay the corrected tax, the fixed penalty and the percentage penalty promptly once the disclosure is accepted.
- Keep the confirmation and supporting file for your records — the FTA can revisit it in a later audit.
How the percentage penalty actually scales
Two penalties apply to a voluntary disclosure. The first is fixed: AED 1,000 for a first disclosure, AED 2,000 for a repeat within 24 months. The second is a percentage of the tax difference, and it rises with every year that passes between the original return's due date and the day you actually disclose — roughly 5% within the first year, 10% in the second year, 20% in the third, 30% in the fourth, and 40% after four years. The practical effect is blunt: the same underpaid amount can cost roughly eight times more to correct in year five than it would have cost to correct in year one, before the fixed fee or any late-payment penalty already accrued is even added. Disclosure timing, far more than the size or nature of the original error, is what decides the size of the final bill.
- The percentage band is set by how long the error went unreported, not by how the error occurred.
- A small error left for years can end up costing more, in percentage terms, than a larger error caught quickly.
- The fixed penalty and the percentage penalty are both charged — neither replaces the other.
- Interest and any pre-existing late-payment penalty on the original underpayment sit on top of both.
When you do not need a formal disclosure
Not every error needs a voluntary disclosure. Where the tax understatement is AED 10,000 or less, the rules allow the correction to be made directly in the return for the current tax period, with no separate Form 211 and no percentage penalty attached. The threshold is applied per error, not per return, so several small errors in the same return can still push the combined understatement over the line and require a formal disclosure. Even where the simpler route applies, keep working papers showing what was corrected and why — the FTA can and does test this during a later audit.
- The AED 10,000 threshold is tested against each individual error, not the return as a whole.
- A next-return correction still needs documentation — it is simplified, not informal.
- If in doubt whether an error is under or over the threshold, treat it as over the threshold until confirmed.
- A voluntary disclosure filed once an FTA audit of the same period has begun loses most of its cost advantage — move before the notice arrives, not after.

Frequently Asked Questions
For businesses correcting a past VAT or corporate tax filing, these are the questions we hear most often once an error has been found.
What is a voluntary disclosure?
A formal correction (Form 211) submitted through EmaraTax when you find an error in a filed VAT or corporate tax return. It replaces the original figures with corrected ones and triggers a fixed penalty plus a percentage penalty on the tax difference.
How much does it cost?
A fixed amount — AED 1,000 first time, AED 2,000 for a repeat within 24 months — plus a percentage of the tax difference that rises from roughly 5% within the first year to 40% after four years. Disclosing earlier keeps you in the lower bands.
When should I file one?
As soon as you identify a material error and before the FTA opens an audit of that period — the sooner you correct it, the lower the percentage penalty band and the lower the accrued cost overall.
Can Exiloz prepare the VDF?
Yes. We quantify the exposure, confirm whether a formal disclosure is even required, prepare the disclosure and manage settlement and FTA correspondence throughout.
What happens if I disclose after the FTA has already opened an audit?
A disclosure made once an audit of the same period is underway loses much of its benefit — the reduced percentage bands generally assume you moved first, before the FTA made contact.
Do I need a voluntary disclosure for a AED 5,000 error?
Usually not. Where a single error understates tax by AED 10,000 or less, it can typically be corrected directly in the current period's return instead of through a formal disclosure.
Does a voluntary disclosure count as an admission of wrongdoing?
No. It is the mechanism the law provides for correcting a genuine error, and using it promptly is exactly what keeps the cost down compared with the FTA finding the same error later.
What documents does the FTA expect with a disclosure?
Typically the invoices, ledgers and workings that support the corrected figures, along with a clear explanation of what went wrong and how the correct amount was calculated.
Correct it at the lowest cost
Exiloz quantifies the exposure, checks whether a formal disclosure is even required, and files a clean voluntary disclosure so you fix errors while the percentage penalty band is still at its lowest.
