Key takeaways
- A UAE VAT error that understates the tax you owe must be reported to the Federal Tax Authority (FTA); an error that overstates it can be reported but doesn't have to be, under Article 10 of Federal Decree-Law No. 28 of 2022 on Tax Procedures.
- When a VAT return error is worth more than AED 10,000, the business must file a voluntary disclosure with the FTA within 20 business days of discovering it.
- When a VAT return error is AED 10,000 or less, the business can correct it in a later VAT return, and files a voluntary disclosure only if no later return is available to carry the correction.
- Since 14 April 2026, a voluntary disclosure made before the FTA notifies a tax audit carries a penalty of 1% of the tax difference per month or part month; waiting until after audit notification adds a fixed 15% penalty.
- Any correction filed late costs more every month, so a UAE business that finds a VAT error should record the discovery date and file promptly.
When do I have to file a voluntary disclosure for a VAT error?
You must file a voluntary disclosure when an error in a VAT return means you paid too little tax, and the rules treat anything above AED 10,000 as the point where a formal filing is required. Article 10 of Federal Decree-Law No. 28 of 2022 makes disclosure mandatory where a return understates the payable tax, and optional where it overstates it.
The Executive Regulation, Cabinet Decision No. 74 of 2023, sets the working rules. For errors above AED 10,000 you file within 20 business days of discovering the error. The Executive Regulation was amended by Cabinet Decision No. 17 of 2026, in force from 1 April 2026, to clarify the voluntary disclosure procedure.
| Size of the error | How you correct it | Deadline |
|---|---|---|
| Above AED 10,000 | Voluntary disclosure to the FTA | 20 business days from discovery |
| AED 10,000 or less | Adjustment in a later VAT return | Within the later return that applies |
| AED 10,000 or less, no later return available | Voluntary disclosure to the FTA | 20 business days from discovery |
| Tax overpaid | Optional voluntary disclosure | No mandatory deadline; five-year limit applies |

How do I file a VAT voluntary disclosure on EmaraTax?
You file a VAT voluntary disclosure through EmaraTax, the FTA's online portal, by opening the return that contains the error and submitting the corrected figures with an explanation. The FTA's published process asks for a letter that describes the background and each error.
- Log in to EmaraTax with the right entity selected.
- Open the VAT tab and find the return, assessment or refund application that contains the error.
- Choose the voluntary disclosure option (the VAT 211 form).
- Enter the corrected figures against the affected boxes.
- Describe each error, the period it sits in and the date you found it, and attach the explanatory letter.
- Submit, then watch the portal for FTA queries.
- Pay the extra tax and any penalty within 20 business days of submitting the disclosure.
If you're part of a VAT group, only the representative member can submit; other members can view the disclosure but not file it.
What are the penalties for correcting a VAT return late?
The penalty for a VAT correction depends on whether you disclose before or after the FTA tells you it is auditing you, and it grows with every month. Cabinet Decision No. 40 of 2017, as amended by Cabinet Decision No. 129 of 2025 from 14 April 2026, sets the rates.
| Situation | Penalty | Source row |
|---|---|---|
| Voluntary disclosure before an audit notice | 1% of the tax difference per month or part month, from the day after the return due date to the day you submit | Table 1, item 11 |
| No disclosure before an audit notice | Fixed 15% of the tax difference, plus 1% per month or part month | Table 1, item 12 |
| Incorrect return | AED 500, unless corrected by the filing deadline or by a disclosure that doesn't change the tax due | Table 1, item 10 |
| Payable tax not settled on time | 14% per annum, charged monthly on unpaid tax | Table 1, item 9 |

Say a SHAMS trading company under-declared AED 30,000 of output VAT in a quarterly return and files a disclosure four months after the return's due date (this is an invented example, not a client case). At 1% per month or part month, the penalty would be about AED 1,200 on top of the AED 30,000. Had the FTA notified an audit first, the fixed 15% would add AED 4,500 before the monthly charge.
How long do I have to correct a VAT error?
You have 20 business days from discovering an above-threshold error to file the disclosure, and a hard outer limit of five years from the end of the tax period. Article 46 of the Tax Procedures Law bars a voluntary disclosure filed more than five years after the end of the relevant period.
The 20 days start on discovery, not on the date the error was made. That makes the discovery date a fact worth proving: write down who found the error, how and when, on the day it happens.

What do most guides not tell you about VAT corrections?
Most guides stop at "file a disclosure if it's over AED 10,000." These edge cases are where businesses lose time or money.
- The AED 10,000 line is the FTA's test, not yours. A small error can sit in a return you can no longer correct through a later return, for example when you're deregistering and have no return left to file. In that case the disclosure route applies whatever the size.
- Errors with no tax effect aren't automatically ignorable. Article 10(5) of the Tax Procedures Law text on the UAE legislation portal requires a return error that creates no tax difference to be corrected through a voluntary disclosure. Secondary sources say later FTA decisions relaxed this; confirm against the FTA's current guide before relying on that.
- Gather every error before you submit. Several mistakes found in one period are easier to explain, price and pay as a single disclosure than as a trickle of separate ones. Because penalty is charged by month, though, don't hold a known error back while you hunt for others.
- Overpayments can be reclaimed, but only inside the five-year window. Because disclosure on overstated tax is optional, nobody chases you to do it; a refund simply expires.
Frequently asked questions
When do I need to file a voluntary disclosure for VAT?
You need to file one when an error in a VAT return understated the tax you owe by more than AED 10,000, within 20 business days of finding it. Below that size you can usually correct the error in your next available return instead.
What is the 5-year record keeping rule for VAT?
The ordinary retention period for VAT records is five years, and it can be extended in some refund cases, so check the current Tax Procedures Law before you discard anything. Keep your correction working papers and the discovery date with the original return records.
How long does a VAT refund take?
The FTA doesn't publish a fixed refund turnaround that Qawi could confirm from an official source, so the time depends on how complete your application is and whether the FTA queries it. Track the application status on EmaraTax and answer any request promptly.
What is a VAT group and should I join one?
A VAT group lets related UAE businesses register together under one tax registration, so intra-group supplies fall outside VAT and one representative member files for all. Whether it suits you depends on your group's structure and your VAT position, which is a question to take to a tax adviser; for corrections, only the representative member can file the voluntary disclosure.
Which deadlines apply to your company?
VAT corrections sit alongside your return dates, free zone renewals and corporate tax filings, and a missed date costs penalty every month. The free UAE compliance calendar lists the deadlines that apply to your company.
