NAQIXCorrecting UAE VAT errors: next return or voluntary disclosure?
Sooner or later every business finds a mistake in a VAT return it has already filed: a sale counted twice, VAT claimed on an expense that was blocked, a reverse charge missed. What happens next depends mainly on the size of the error. Here is how the two correction routes work in broad terms, and how to fix the books so the same error does not come back.
First, is it an error at all?
Not every change to an earlier sale is an error. If goods come back or a discount is agreed after the sale, you issue a tax credit note, and it generally adjusts the return for the period in which it is issued. Nothing in the earlier return was wrong. An error is something that was incorrect when the return was filed: a supply left out, a wrong rate, input tax claimed without a valid tax invoice, a document counted twice.
The two routes
In broad terms, UAE VAT law gives two ways to correct an error in a return already submitted:
- Correct it in the next return. Where the error results in a tax difference of AED 10,000 or less, it can generally be corrected in the return for the period in which the error is discovered.
- Submit a voluntary disclosure. Where the tax difference is more than AED 10,000, a voluntary disclosure is generally required, submitted through EmaraTax within a short period, typically 20 business days, of becoming aware of the error.
Penalties can apply to errors and to late disclosures, and the penalty rules have been revised over time. Errors that do not change the tax due may still need a disclosure in some cases. Confirm the route, the deadline and any penalty for your situation with your tax adviser before acting.
Common errors and how they usually surface
| Error | How it is often found |
|---|---|
| A sale recorded twice | Customer statement disputes, or the documents behind a VAT 201 box |
| VAT claimed on blocked expenses | A review of input tax by expense account |
| Reverse charge missed on an overseas service | A review of foreign suppliers with no VAT on their bills |
| Wrong emirate on branch sales | Comparing boxes 1a to 1g with branch sales |
| Draft or cancelled documents on the return | Tying the return to the VAT accounts |
| Foreign-currency sale at the wrong rate | Comparing invoice rates with the rate used in the books |
An illustrative example
Take a hypothetical trading company that files quarterly. While preparing the second-quarter return it finds that, in the first quarter, a supplier bill was entered twice and the VAT on it, AED 2,400, was recovered twice. The tax difference is AED 2,400, below AED 10,000, so in broad terms the company can correct it in the second-quarter return by reducing its recoverable input tax, and reverse the duplicate bill in the books with a reference to the original.
Now suppose the same review finds a large local sale that was wrongly zero-rated as an export, with AED 15,000 of VAT missing. That difference is above AED 10,000, so a voluntary disclosure for the first quarter would generally be needed instead. The figures are invented for illustration; your adviser decides the route for real cases.
Finding errors before the FTA does
Most errors are cheapest to find before the return is filed. A short routine each period catches the majority: open the documents behind each box, read the list of documents left off the return and why, tie output and input VAT to the VAT accounts, and look for duplicates by customer, date and amount. Once a year, produce an FTA Audit File for the year and check that it agrees with the returns you filed.
Fixing the books, not only the return
Correcting the return without correcting the books leaves the same error in next year's figures. Keep three rules:
- Leave closed periods closed. Do not edit or delete documents in a filed period. Post the correction in the current period with a reference to the original document, or issue a credit note where the correction is to a customer invoice.
- Keep a working paper. Record what was wrong, the documents involved, the tax effect and whether it went in the next return or a voluntary disclosure.
- Have a second person approve it. The person who finds an error should not be the only person who decides how to correct it.
How NAQIX helps
- The VAT 201 report lists the documents behind each box and the documents left off the return, with the reason, so errors can be traced to their source.
- The month-end close is signed off by a second person and then locks the month for posting; reopening a month needs a recorded reason.
- Reverse-charge treatment can be changed per bill until the period is closed, and is refused after that.
- Manual journals are voided or corrected through the Finance Control Centre, with a full audit trail, rather than edited in place, and credit notes can be raised against the original invoice.
- The FTA Audit File reconciles to the VAT 201 return for any period, which makes it a useful cross-check.
NAQIX does not prepare or submit voluntary disclosures and does not file VAT returns; you or your tax agent do that in EmaraTax. The Tax & compliance and Accounting & reports pages list the features, the UAE VAT billing overview covers invoicing, and the NAQIX page for the UAE describes the local setup.
