VAT Audit in UAE 2026: How to Prepare for an FTA VAT Audit

A VAT audit in the UAE is a review by the Federal Tax Authority (FTA) to check whether a business has calculated, reported and paid VAT correctly.

For a VAT-registered company, preparing for an FTA VAT audit means being able to support the figures reported in the VAT returns with the accounting records and documents behind them. Sales should agree with the sales ledger, input VAT should be supported by purchase records and valid tax invoices, imports should agree with customs records, and any difference between the VAT return and the accounts should have a clear explanation.

This matters even if the business has never received an FTA audit notice.

A VAT return may have been filed correctly at the time, but problems often appear later when the company can no longer explain a manual VAT adjustment, locate export documents, reconcile an old VAT control account or show why input VAT was claimed on a particular purchase.

VAT audit preparation is therefore best treated as part of normal VAT compliance rather than a separate exercise carried out only after the FTA contacts the company.

The need for this has increased in 2026. Changes to the UAE VAT Law and Tax Procedures Law took effect from 1 January 2026, administrative penalty rules changed from 14 April 2026, and the UAE Electronic Invoicing System has entered its implementation stage. These changes affect areas such as reverse charge transactions, input VAT, VAT refunds, correction of errors and invoice data.

This guide explains how to prepare for a VAT audit in the UAE, what records should be checked, how VAT returns should be reconciled with the accounts and which 2026 VAT changes finance teams should now include in their review.

What Is a VAT Audit in the UAE?

A VAT audit is carried out by the Federal Tax Authority to check whether a person has complied with UAE tax law.

The FTA can examine VAT returns together with the accounting records, invoices and other information connected with those returns. A tax audit may be carried out at the FTA’s premises, at the business premises of the person being audited or at another location where the person carries on business, stores goods or keeps records.

Under the Tax Procedures Law, the FTA must normally notify the person at least 10 days before a tax audit. The current Executive Regulation refers to at least 10 business days before the audit is conducted. The company should always follow the date, scope and requirements stated in the notice it actually receives.

An FTA VAT audit does not have to cover every transaction the business has ever made. The review may relate to particular tax periods, transactions or issues.

That is why the first step after receiving an FTA VAT audit notice should be to read the request carefully and establish exactly what the FTA is asking for.

Sending large amounts of accounting data without first understanding the VAT position can make the response harder to manage.

The finance team should know what each document shows and how it connects with the VAT returns under review.

What to Do When You Receive an FTA VAT Audit Notice

The company should first confirm which legal entity and Tax Registration Number are covered by the notice.

This sounds basic, but it becomes important where a group has several companies, branches, free zone entities or VAT registrations.

The VAT periods stated in the notice should then be matched with the filed returns and the accounting periods in the company’s system.

The person managing the response should obtain the original VAT returns, the workings used to prepare them and the general ledger for the same periods.

Before information is submitted, the company should check whether the VAT return can still be reproduced from the books.

If the return cannot be reconciled internally, that difference should be investigated before the records are sent.

For example, a business may have reported AED 8.4 million of standard-rated supplies in a VAT return while the sales accounts show AED 9.1 million for the same period.

That does not automatically mean AED 700,000 was omitted from the VAT return.

Part of the difference may relate to zero-rated exports. Some invoices may have been issued in a different VAT period. There may also be credit notes, deposits, asset disposals or accounting entries that do not follow the same timing as VAT.

The important point is that the company should be able to explain the AED 700,000 difference.

If nobody can explain it, the reconciliation is not complete.

How to Prepare for an FTA VAT Audit

The strongest starting point for VAT audit preparation is the accounting system.

Take the numbers reported in the VAT return and work backwards until they can be matched with the general ledger and then with the underlying transactions.

For sales, this means understanding how the total supplies reported in the VAT return were built from the sales ledger.

For purchases, it means understanding how the input VAT claimed in the VAT return was built from purchase invoices and VAT accounts.

This approach is much more useful than simply checking whether a folder contains invoices.

A company can have every invoice and still have a wrong VAT return.

It can also have a correct VAT return but poor supporting records.

A proper VAT audit review checks both.

Reconcile Sales With the VAT Return

Start with the sales ledger or revenue accounts for each VAT period.

Compare the figures with the amounts reported in the VAT return and separate the differences.

Standard-rated sales should be checked against the output VAT reported.

Zero-rated sales should be identified separately so that the documents supporting the 0% treatment can be reviewed.

Exempt income should not be mixed with zero-rated supplies because the VAT treatment and effect on input VAT can be different.

Credit notes should also be checked carefully.

If a sales invoice was raised in one VAT period but cancelled or reduced later, the accounting entry and VAT adjustment may fall in different periods. That can produce a valid difference between the ledger and the VAT return, but the company should be able to trace it.

Advance payments can cause similar problems.

The accounting team may not recognise the full amount as revenue immediately, while VAT may become due under the date-of-supply rules.

This is particularly important for construction companies, professional services businesses and companies working under milestone or long-term contracts.

Check Output VAT Separately From Sales

A company should not stop after reconciling the sales value.

Output VAT should be reconciled separately.

The sales figure can agree with the VAT return while the VAT itself is wrong.

For example, an invoice may have been posted to the correct revenue account but given the wrong VAT code. A transaction may also have been recorded at 0% instead of 5%, or a manual journal may have been posted directly to the VAT account.

The output VAT control account should therefore be compared with the VAT reported for each period.

Any manual entries should have a clear reason and supporting calculation.

Old manual journals deserve particular attention because staff may remember why they were posted at the time but lose that knowledge after employees leave or systems change.

Reconcile Input VAT With the Purchase Records

The same process should be applied to purchases.

Start with the input VAT recorded in the accounting system and compare it with the amount recovered in the VAT return.

If the ledger shows AED 340,000 of input VAT but only AED 305,000 was claimed, the AED 35,000 difference should be understood.

It may relate to expenses where VAT was not recoverable, invoices claimed in another period, incomplete documents or VAT deliberately excluded from the return.

If the VAT return shows more input VAT than the ledger, that also needs an explanation.

The important point is that input VAT should not appear in the return without a clear link to the accounting records.

For larger purchases, the review should go further than the general ledger.

The invoice, supplier, business purpose, payment information and supporting contract should be checked where the size or nature of the transaction makes this necessary.

VAT Control Accounts Are Often Where Old Problems Appear

VAT control accounts can show issues that are not obvious from looking at individual returns.

A VAT payable balance should normally move in a way that can be explained by the VAT return, payments to the FTA and any permitted adjustments.

If the VAT control account has contained the same unexplained balance for two or three years, it should be investigated.

The balance may relate to an old return, a payment posted to the wrong account, a manual journal, a VAT amount that was never claimed or an adjustment that was not reflected correctly in EmaraTax.

The same applies to recoverable VAT balances.

A business should know whether the amount represents current input VAT, an old refund balance or an accounting difference.

This becomes more important because the 2026 tax changes introduced time limits affecting VAT refund and credit balances.

What Documents Are Needed for a VAT Audit in the UAE?

The exact documents depend on the business and the FTA request.

For most companies, the audit file begins with the VAT returns and the calculations used to prepare them. Those returns should then connect with the trial balance, general ledger, sales records, purchase records and VAT control accounts.

Sales should be supported by tax invoices and, where needed, contracts, customer orders, delivery documents and credit notes.

Purchases should be supported by supplier tax invoices together with the records needed to show what was bought and why the business incurred the cost.

Bank statements may help support payments, refunds or unusual transactions.

A trading or manufacturing company may need customs declarations, freight documents, bills of lading, airway bills and inventory records.

An e-commerce business may also need marketplace reports, payment gateway statements and refund records.

A construction business may need contracts, payment certificates, variation orders and advance-payment records.

The point is not to collect every document the company owns.

The document should help explain the VAT treatment of the transaction being reviewed.

Check UAE Tax Invoices Properly

Tax invoice compliance should form part of every VAT audit review.

The UAE VAT Law requires a registrant to issue a tax invoice within 14 days from the date of supply, subject to the VAT date-of-supply rules. The VAT Executive Regulation sets out the information required on a tax invoice.

A finance team should not treat an invoice as valid simply because “Tax Invoice” appears at the top.

The supplier’s legal details and TRN should be checked. The invoice date, description of the goods or services, taxable value and VAT amount should make sense for the transaction.

Where the invoice is in a foreign currency, the VAT reporting and AED amounts should also be checked against the UAE VAT requirements.

For purchase invoices, the business should also confirm that the invoice belongs to the company claiming the VAT.

An invoice addressed to another group company should not simply be posted into the VAT return of a different entity because the cost was paid from the same group bank account.

For businesses processing thousands of invoices, the better approach is to look for repeated problems.

If the ERP system is generating the same incorrect VAT information on every invoice, the issue can affect a large number of transactions rather than one document.

Input VAT Needs More Attention Under the 2026 VAT Changes

Input VAT is one of the most important areas in a VAT audit because it reduces the VAT payable by the business.

From 1 January 2026, amendments to the UAE VAT Law also strengthened the rules around input tax where a transaction forms part of a tax-evasion arrangement.

The Ministry of Finance states that the amendments allow the FTA to deny input tax where a supply forms part of such an arrangement and require taxpayers to verify the legitimacy and integrity of supplies before deducting input tax in line with the procedures set by the FTA.

For normal businesses, this makes the commercial file behind a large or unusual purchase more important.

A purchase should make sense.

The supplier should be identifiable. The goods or services should have been received. The payment route should be understandable. The transaction should have a clear business purpose.

This does not mean every supplier needs a large investigation before an invoice is paid.

It means the business should not ignore obvious questions around an unusual transaction and rely only on the fact that it has received a document showing VAT.

For higher-value or unusual purchases, keeping the contract, purchase order, delivery evidence and payment information with the tax invoice can make the transaction much easier to explain later.

Zero-Rated Sales Need Proper Evidence

Zero-rated sales are another important area for UAE businesses involved in exports.

A 0% VAT code in the accounting software does not prove that the transaction qualified for zero-rating.

The supporting documents should show what was supplied, who the customer was and, where relevant, how the goods left the UAE.

The sales invoice should agree with the shipping and customs records.

If the invoice shows one customer and the export documents show another party, the company should understand why.

If the export declaration shows a different value from the commercial invoice, the difference should be explained.

The same applies when freight forwarders or related companies appear in the shipping chain.

The strongest audit file connects the commercial transaction with the export evidence rather than keeping the two sets of documents in separate folders with no clear link between them.

Imports Should Be Reconciled With Customs Records

Import VAT deserves a separate review for trading, logistics and manufacturing companies.

The accounting system and customs records may not always start from exactly the same information.

The company should compare imported purchases with the customs data for the same periods and make sure the legal entity acting as importer is clear.

This becomes especially important where customs brokers, freight forwarders or related companies are involved.

For example, goods may have been purchased by Company A but imported under the customs details of Company B.

The stock may still arrive in the correct warehouse, so the commercial team sees no problem.

For VAT purposes, however, the company needs to understand which entity made the import and which entity is using the VAT treatment.

Differences between customs values and accounting values can also arise for valid reasons, but they should be understood rather than ignored.

For larger imports, the supplier invoice, customs declaration, shipping records and accounting entry should be easy to connect.

Review Reverse Charge Transactions

Businesses receiving certain goods or services from outside the UAE should check whether the reverse charge mechanism applies.

These transactions are commonly missed because the overseas supplier does not charge UAE VAT.

Software subscriptions, consultancy fees, management charges and other overseas services are examples of areas that should be reviewed rather than assumed to be outside the VAT return.

The finance team should compare foreign suppliers with the VAT treatment used in the accounts.

A 2026 change to reverse charge documentation

From 1 January 2026, the amended VAT Law removed the requirement for taxable persons to issue self-invoices when applying the reverse charge mechanism. Businesses must instead keep the supporting documents relating to the supply as required by the VAT rules.

This is a useful example of why a VAT audit checklist written several years ago should not simply be reused in 2026.

The transaction still needs to be supported, but the required process has changed.

Scrap metal businesses have an additional 2026 VAT change

Businesses dealing in scrap metal should also review Cabinet Decision No. 153 of 2025.

From 14 January 2026, the reverse charge mechanism applies to qualifying scrap-metal supplies between VAT registrants where the required conditions are met. The buyer becomes responsible for accounting for the VAT, while the supplier and recipient have specific steps to complete before the supply.

For a scrap-metal trader, this should be tested separately from ordinary domestic purchases because the invoice and declarations need to reflect the special treatment.

VAT Audit Preparation for Free Zone Companies

A free zone company should not assume that all of its transactions are outside UAE VAT.

The VAT treatment depends on what the business is actually supplying.

This is particularly important for businesses operating in Designated Zones.

A trading company may have goods moving between a Designated Zone and mainland UAE, goods transferred between zones, imports, exports and local supplies during the same VAT period.

The invoice should agree with the actual movement of the goods.

Customs and shipping records should support that movement.

Services should also be reviewed separately because free zone or Designated Zone status does not automatically give services the same VAT treatment as goods.

For an FTA VAT audit, a statement such as “we are a free zone company” is not enough to explain the VAT treatment.

The transaction needs to be checked on its own facts.

VAT Audit Preparation for Trading and Distribution Companies

Trading companies usually have several parts of the VAT record moving at the same time.

Purchases affect the supplier ledger and input VAT. Imports may also appear in customs data. Goods then move through inventory before being sold locally or exported.

Returns, rebates and supplier credit notes can create further adjustments.

For this type of business, the best VAT audit preparation is to connect these records instead of reviewing each one separately.

An imported purchase should be traceable to the supplier record, customs entry, inventory receipt and VAT treatment.

An export sale should be traceable to the customer invoice and export records.

If goods are returned, the sales and VAT adjustment should agree with the credit note and stock movement.

Companies with several warehouses should also make sure the warehouse location has not caused transactions belonging to different legal entities or TRNs to be mixed in one report.

VAT Audit Preparation for Construction Companies

Construction businesses should pay particular attention to VAT timing.

The accounting treatment for a project does not always determine when VAT becomes due.

Advance payments, payment certificates, milestone invoices, retention amounts and contract variations can all affect the VAT records.

For example, a finance team may recognise revenue gradually for accounting purposes while the VAT position follows invoices, payments or another date-of-supply event.

The project file should therefore be reviewed together with the VAT return.

The contract, payment certificate, invoice, receipt and accounting entry should tell a consistent story.

Variation orders should also be checked.

A change in contract value can create additional invoices or credit notes, and the VAT effect should be reflected in the correct period.

VAT Audit Preparation for E-Commerce Businesses

E-commerce businesses often need to reconcile several systems.

The accounting software may show only the net settlement received from an online marketplace or payment processor, while the VAT return should be based on the underlying transactions.

For example, a marketplace may collect AED 1 million from customers, deduct AED 100,000 of fees and refunds, and pay AED 900,000 into the company’s bank account.

The AED 900,000 bank receipt is not necessarily the sales figure for VAT purposes.

The company should be able to reconcile marketplace sales, refunds, commissions, payment-gateway amounts and the entries posted to the general ledger.

Refunds deserve particular attention because the customer refund, marketplace adjustment, credit note and accounting entry may be recorded on different dates.

Businesses selling through more than one platform should also check that each platform is linked to the correct company and VAT registration.

Compare VAT Returns With the Financial Statements

VAT sales and financial statement revenue do not always have to match.

They often will not.

Accounting rules and VAT rules can recognise or present transactions differently.

However, the difference should be understood.

A useful annual review starts with revenue in the trial balance or audited financial statements and compares it with supplies reported across the VAT returns for the year.

Differences may relate to zero-rated transactions, exempt income, VAT timing, advance payments, asset sales or other items.

The exercise is especially useful now that UAE businesses may also have Corporate Tax filings based on their financial accounts.

VAT and Corporate Tax are separate taxes, and the figures do not need to be identical.

But if the company’s own records show materially different revenue figures in different tax filings, management should know why.

Review Old VAT Refund and Credit Balances

Businesses carrying old VAT credit balances should now review them carefully.

The 2026 VAT and Tax Procedures amendments introduced new time limits for claiming excess refundable VAT and credit balances.

The Ministry of Finance states that the VAT amendments introduced a five-year time limit for submitting requests to reclaim excess refundable VAT after reconciliation. Once the period expires, the right to reclaim the amount can expire.

Separate Tax Procedures amendments also set a period of up to five years from the end of the relevant tax period for requesting the refund of a credit balance with the FTA or using that balance to settle tax liabilities. Transitional rules apply to certain older balances.

For a finance team, this means an old credit balance should not simply remain on the books year after year.

The company should identify when the balance arose, confirm that it agrees with EmaraTax and check whether the documents supporting the amount are still available.

Businesses with significant historical VAT credits should review the position before the relevant time limit is reached.

What If You Find a VAT Error Before an FTA Audit?

If a VAT error is found, the first step is to understand the error rather than immediately changing the next return.

Identify the affected VAT period.

Work out whether the business underpaid VAT, overclaimed VAT, understated a refund or made an error that does not change the final tax amount.

The cause should then be identified.

Was an invoice omitted? Was the wrong VAT code used? Was input VAT claimed in the wrong period? Was an import missed? Did a credit note remain unprocessed?

Only after the issue has been quantified should the correction method be considered.

Under the current Tax Procedures Executive Regulation, where the tax difference is more than AED 10,000, a Voluntary Disclosure must be submitted within 20 business days after the person becomes aware of the error. The Regulation provides separate correction rules for errors of AED 10,000 or less.

This is an important point because some VAT articles state that every error, regardless of amount, now requires a Voluntary Disclosure.

That is not what the current Executive Regulation says.

The correct procedure should be checked against the current rules and the facts of the case.

UAE VAT Penalties Changed in April 2026

The UAE administrative tax penalty rules changed from 14 April 2026 under Cabinet Decision No. 129 of 2025.

The FTA confirmed that a number of penalties were reduced and that calculation methods were changed for several tax violations.

The amendments cover matters including incorrect tax returns, late tax payments, Voluntary Disclosures, failure to make a required Voluntary Disclosure before notification of a tax audit and certain failures to update tax records.

This makes old penalty articles particularly risky.

A business should not assume that a penalty table published in 2021, 2022 or 2025 still gives the current result.

The actual penalty depends on the type of violation, the timing and the rules applying to the case.

For an FTA VAT audit, the more useful approach is to understand and correct the underlying VAT issue rather than trying to estimate a penalty from an old online table before the facts have been reviewed.

VAT Audit Record Keeping

VAT audit preparation also depends on being able to retrieve records after several years.

Documents should therefore be stored in a way that allows the company to find them by VAT period, customer, supplier or transaction.

Keeping documents in individual employees’ email inboxes is not a reliable long-term record system.

The same applies to files saved only on a former employee’s laptop.

For real property, the VAT Executive Regulation requires relevant records to be kept for 15 years following the end of the tax period to which they relate.

Companies should also consider whether refund claims or other tax procedures extend the period for which particular records need to remain available.

The important point for audit preparation is simple: a document that technically exists but cannot be found when it is requested is of little practical use.

UAE E-Invoicing and VAT Audit Readiness in 2026

UAE e-Invoicing should now form part of VAT planning.

The Electronic Invoicing System uses structured invoice data that is issued and exchanged electronically between supplier and buyer and reported electronically to the FTA.

The Ministry of Finance specifically states that PDFs, Word documents, images, scanned copies and ordinary emails are not e-Invoices under the system.

This matters for VAT audit readiness because many of the data fields needed for e-Invoicing are also important for ordinary VAT compliance.

Customer names need to be correct. Supplier records need to be correct. TRNs need to be maintained properly. VAT codes, invoice dates, credit notes and transaction values should be accurate in the accounting system.

An invoice problem that is currently corrected manually after the invoice has been issued may become much harder to ignore once structured invoice data is being validated electronically.

UAE E-Invoicing Deadlines for 2026 and 2027

The UAE e-Invoicing pilot programme began on 1 July 2026.

For businesses with annual revenue of AED 50 million or more, the original deadline to appoint an Accredited Service Provider was 31 July 2026. The Ministry of Finance extended that deadline to 30 October 2026 in May 2026.

The mandatory implementation date for those businesses remains 1 January 2027.

Businesses with annual revenue below AED 50 million must appoint an Accredited Service Provider by 31 March 2027 and implement the Electronic Invoicing System from 1 July 2027 under the published timetable.

For larger businesses, this means the work should already be underway in 2026.

The finance team should not leave the project only with the IT department.

The accounting and tax teams need to check whether the information held in the ERP is complete enough to support correct VAT reporting.

What Should Be Checked Before UAE E-Invoicing Goes Live?

A useful starting point is to look at the data already used to create sales invoices.

Are customer legal names correct?

Do VAT-registered customers have the right TRN in the system?

Do credit notes refer back to the right transactions?

Are invoice dates and tax dates handled correctly?

Are products and services mapped to the correct VAT treatment?

These questions are already relevant to a VAT audit.

E-Invoicing simply makes data quality more visible because the information is exchanged in a structured form.

Businesses should also check whether different business units are creating invoices outside the main ERP.

Manual invoices produced in spreadsheets, Word or separate billing systems can become a problem if those processes are not included in the e-Invoicing project.

UAE E-Invoicing Penalties

The UAE has also introduced specific administrative fines for businesses that are required to implement the Electronic Invoicing System.

The Ministry of Finance states that failure to implement the system or appoint an approved service provider within the required time can result in AED 5,000 per month.

Failure to issue or send an electronic invoice within the specified timeframe can result in AED 100 per invoice, subject to a monthly cap of AED 5,000 for that violation. Separate penalties apply to electronic credit notes and certain failures to notify the FTA or service provider about system or data issues.

These e-Invoicing penalties are separate from the ordinary question of whether VAT on the underlying transaction was calculated correctly.

For finance teams, the lesson is that invoice data, VAT treatment and system readiness now need to be reviewed together.

What Happens After an FTA VAT Audit?

During an FTA audit, the company may receive further requests for documents or explanations.

Responses should be consistent with the accounting records already provided.

If a contract says one thing, the invoice says another and the VAT return was prepared on a third basis, the company should understand the difference before responding.

Where a tax assessment or other official decision is issued, the company should read the decision carefully and identify the factual and legal basis.

If the company disagrees with an official FTA decision, a reconsideration request may be available.

The FTA’s current service information states that a reconsideration request must generally be raised within 40 business days from the date of the original decision. The FTA may take up to 45 business days to respond to a completed reconsideration request, subject to the rules allowing an extension.

Not every FTA communication is a decision that can be reconsidered.

A normal request for information, clarification or correspondence during an audit should not automatically be treated as a reconsideration matter.

How Athos Reviews VAT Audit Readiness

A useful VAT audit review should start with the filed returns and the accounts rather than with a generic document checklist.

Athos can review the VAT returns for the periods in scope and reconcile them with the general ledger, sales records, purchase records and VAT control accounts.

Where differences are found, they can be separated by VAT period and transaction type.

For example, a sales difference may relate to exports, credit notes, advances or VAT timing.

An input VAT difference may relate to restricted costs, missing invoices or an amount claimed in another period.

An import difference may need to be checked against customs records.

A long-standing VAT control-account balance may need to be traced back through earlier returns and payments.

This approach helps management understand the reason for the difference rather than simply receiving another list of documents to provide.

For businesses that have already received an FTA VAT audit notice, the review can focus first on the tax periods and information requested by the FTA.

For businesses that have not received a notice, the same work can be used as a VAT compliance review to identify issues before they become part of an audit.

VAT Audit Services for Trading, Logistics and Manufacturing Companies

Athos works with UAE businesses whose VAT records involve more than simple sales and purchase invoices.

For trading and distribution companies, VAT audit preparation may involve imports, exports, customs records, inventory, rebates, returns, credit notes and goods in transit.

For logistics companies, the review may include cross-border services, freight records, subcontractor costs, customs documentation and customer billing.

Manufacturing companies can have additional VAT issues around imported raw materials, local purchases, capital expenditure, scrap, stock movements and sales of finished goods.

These businesses often benefit from a VAT review that follows the transaction from the original commercial record through to the VAT return.

VAT Audit Services for Free Zone Companies

Free zone businesses often need additional care because the VAT result depends on the transaction rather than simply the company’s location.

Athos can review mainland sales, imports, exports, Designated Zone transactions and movement of goods between locations.

Where the business handles both goods and services, those supplies should also be considered separately.

The aim is to make sure the VAT treatment used in the accounting system agrees with what actually happened in the transaction.

VAT Audit Services in Dubai and Across the UAE

Athos Auditors provides VAT audit preparation and VAT compliance support for businesses in Dubai and across the UAE.

The work can include VAT return reconciliation, VAT control-account review, input and output VAT testing, tax invoice checks, imports, exports, reverse charge transactions, free zone transactions, zero-rated supplies and review of errors identified in earlier VAT periods.

Where a company is preparing for UAE e-Invoicing, the VAT review can also identify invoice-data issues that should be corrected before structured invoicing becomes mandatory.

The purpose is straightforward.

The business should know what it reported, where the number came from and which documents support it.

Frequently Asked Questions About VAT Audits in the UAE

What is a VAT audit in the UAE?

A VAT audit is a review carried out by the Federal Tax Authority to check whether a person has complied with UAE VAT rules and whether the VAT reported can be supported by the company’s records.

How much notice does the FTA give before a VAT audit?

Under the current Tax Procedures rules, the FTA should normally notify the person at least 10 business days before conducting the tax audit. The company should follow the exact date and instructions stated in the notice it receives.

How do I prepare for an FTA VAT audit?

Start by obtaining the VAT returns and workings for the periods under review. Reconcile sales and output VAT with the general ledger, then reconcile purchases and input VAT. Imports, exports, credit notes, reverse charge transactions and unusual VAT journals should be checked separately where they affect the business.

What documents may be needed for a VAT audit?

The records depend on the scope of the audit but can include VAT returns, VAT workings, sales and purchase invoices, credit notes, general ledgers, trial balances, bank records, contracts, customs declarations and shipping records.

Can the FTA review input VAT claims?

Yes. The company should be able to support input VAT with the required records and show why the cost and VAT treatment belong to the business. The 2026 VAT amendments also strengthened the rules concerning input tax linked to tax-evasion arrangements.

Do VAT returns have to match financial statement revenue?

Not necessarily. VAT and accounting rules can create timing and classification differences. The company should, however, be able to reconcile and explain material differences.

Does VAT apply to UAE free zone companies?

Yes, depending on the transaction. Free zone status does not mean that every transaction is outside VAT. Businesses should review the actual supply, and Designated Zone businesses should pay particular attention to the rules affecting goods.

Did reverse charge VAT change in 2026?

Yes. From 1 January 2026, taxable persons applying the reverse charge mechanism are no longer required to issue self-invoices, but they must keep the required supporting documents for the supply.

What should I do if I find a VAT error?

Identify the VAT period, calculate the tax difference and determine why the error happened before correcting it. The current Tax Procedures Executive Regulation distinguishes between errors above AED 10,000 and smaller differences when setting the correction process.

Have UAE VAT penalties changed in 2026?

Yes. Cabinet Decision No. 129 of 2025 took effect on 14 April 2026 and changed a number of administrative penalties and calculation methods. Old VAT penalty tables may therefore no longer reflect the current rules.

Is there a time limit for old VAT refund balances?

The 2026 amendments introduced five-year rules affecting excess refundable VAT and credit balances, with transitional provisions for certain older balances. Businesses carrying old VAT credits should review when those balances arose and whether action is required.

Is a PDF an e-Invoice under the UAE Electronic Invoicing System?

No. The Ministry of Finance states that PDF files, Word documents, images, scanned copies and emails are not e-Invoices. UAE e-Invoicing uses structured invoice data exchanged electronically through the system.

What is the e-Invoicing deadline for businesses above AED 50 million revenue?

The deadline to appoint an Accredited Service Provider was extended to 30 October 2026. Mandatory implementation for this group remains 1 January 2027.

When does e-Invoicing apply to businesses below AED 50 million revenue?

Under the published timetable, businesses below AED 50 million annual revenue must appoint an Accredited Service Provider by 31 March 2027 and implement the system from 1 July 2027.

Can a company challenge an FTA decision?

An eligible official FTA decision may be subject to reconsideration. The FTA currently states that a reconsideration request must generally be raised within 40 business days from the original decision.

Prepare for an FTA VAT Audit Before Problems Build Up

A good VAT audit file should make the company’s VAT position easy to follow.

The sales reported in the VAT return should be traceable to the sales records.

Input VAT should be traceable to the purchases and supporting invoices.

Exports should have export evidence.

Imports should agree with customs records.

VAT control accounts should agree with returns and payments.

Where something does not match, the business should know why.

That is what makes VAT audit preparation useful.

Athos Auditors can assist businesses with VAT audit preparation, VAT return reconciliation, review of supporting documents and VAT compliance checks in Dubai and across the UAE.

If your company has already received an FTA VAT audit notice, the review can focus on the periods and records requested.

If no notice has been received, a VAT review can help identify accounting and VAT differences before they become part of an FTA audit.
