The Federal Tax Authority has authority to conduct VAT audits of registered businesses in the UAE without prior notice, though most audits are preceded by a notification letter. A VAT audit assesses whether the taxable person has correctly calculated, reported, and paid their VAT obligations. Businesses that maintain their records in accordance with the requirements of the UAE VAT legislation and its Executive Regulations are significantly better positioned to respond without penalties.
Records the FTA Requires You to Maintain
VAT-registered businesses must maintain tax records for a minimum of five years. Auditors focus most closely on the following categories.
Tax invoices issued. Each invoice must include the supplier's name and Tax Registration Number, the date, a sequential invoice number, a description of the supply, the net amount, the applicable VAT rate, and the VAT amount. Missing fields or incorrect TRN numbers are among the most frequent findings in VAT audits.
Tax invoices received. Input tax claims must be supported by compliant tax invoices from the supplier. Claims supported by pro forma invoices, receipts, or invoices from unregistered suppliers are not valid for input tax recovery.
Import documentation. Where a business imports goods or services, the FTA verifies that import VAT was accounted for correctly, whether through the reverse charge mechanism or through payment at the point of import. Customs declarations and import records should be retained and cross-referenced with VAT return entries.
Credit notes. Each credit note must reference the original tax invoice it relates to. VAT adjustments arising from credit notes must be reflected in the return for the correct tax period.
Bank statements. The FTA cross-references declared output tax against actual bank receipts. Unexplained discrepancies between sales reported in returns and amounts received are a significant audit focus.
Common Triggers for VAT Audits
Audits may be conducted on a random or sector-wide basis, but certain patterns in a business's return history increase the likelihood of selection.
Consistent refund claims. Businesses that regularly reclaim more VAT than they collect are subject to closer scrutiny. The pattern may be entirely legitimate, as in a business with substantial capital expenditure, but the documentation supporting every input tax claim must be complete and retained.
Material changes in declared turnover. A sharp increase or decrease in supplies declared across consecutive periods, without a corresponding change in business circumstances, may prompt a review.
Amendments and late filings. A pattern of material amendments to previously filed returns, or a history of late filing, increases audit risk. Where amendments were genuinely necessary, the reasons should be documented and available for inspection.
Sector-based reviews. The FTA has publicly indicated that certain sectors, including real estate, precious metals, and cash-intensive businesses, are subject to more intensive compliance monitoring.
Practical Preparation Steps
Reconcile returns to accounting records. Each VAT return should be traceable to specific entries in your accounting system. A return that cannot be reconciled to underlying records is very difficult to defend in an audit.
Audit invoice formatting compliance. Conduct a sample review of tax invoices issued and received to confirm they contain all required fields. Non-compliant invoices should be identified and the supplier contacted for correction or replacement before the audit, not during it.
Confirm treatment of zero-rated and exempt supplies. The boundary between standard-rated, zero-rated, and exempt supplies is a common area of audit challenge. Confirm that your treatment is correct and that supporting documentation, particularly export evidence for zero-rated supplies, is on file.
Designate a single point of contact. During an FTA audit, all communication should be managed through one designated person who understands the business's VAT position. Uncoordinated responses from multiple staff members increase the risk of inconsistent answers that complicate the audit process.
Preparation for a VAT audit is primarily a documentation exercise. The businesses that navigate audits most effectively are those whose records are complete, organised, and consistently reconcilable to their returns before the auditor arrives.
