VAT in the UAE and the Role of the FTA Audit File
Value Added Tax has applied across the UAE since 1 January 2018 under Federal Decree-Law No. 8 of 2017, at a standard rate of 5%, one of the lowest VAT rates in the world. The tax was introduced to diversify government revenue away from oil income and to help fund infrastructure, tourism and public services.
Since then, the Federal Tax Authority (FTA) has built its compliance model around one central expectation: every VAT-registered business must be able to reproduce its accounting records, on demand, in a structured format the FTA can review quickly. That structured export is what the FTA refers to as the FTA Audit File, commonly abbreviated FAF. It is not a separate tax return or an additional filing obligation. It is a record-keeping and data-format requirement that sits behind the VAT return a business already submits.
What Is the FTA Audit File (FAF)?
The FTA Audit File is a structured electronic export of a business’s accounting data, generated from its accounting software, that the FTA can request during a tax audit or a targeted compliance review. The concept mirrors the Standard Audit File for Tax model used in several other tax jurisdictions: instead of an auditor requesting individual invoices and ledger extracts one at a time, the taxable person’s software produces a single structured file covering the audit period, which FTA officers can load into their own review tools.
The requirement applies to every VAT-registered business, regardless of size or sector, because the obligation is tied to VAT registration itself rather than to turnover or business activity. A business does not need to generate an audit file for every tax period. It needs the standing capability to produce one, complete and reconciled, whenever the FTA asks for it.

What the FTA Audit File Must Include
There is no single template a business can download and fill in. The audit file is assembled from records a compliant accounting system should already be generating, organised into the categories below.
| Record category | What the FTA expects to see |
|---|---|
| General ledger | Full transaction-level entries for the audit period, not summarised totals |
| Sales and output tax records | Tax invoices, invoice numbers, customer TRNs where applicable, VAT charged per line item |
| Purchases and input tax records | Supplier tax invoices, import documentation, VAT recovered per transaction |
| Credit and debit notes | Adjustments linked back to the original tax invoice they correct |
| Customer and supplier master data | Names, TRNs and addresses used consistently across the accounting system |
| Chart of accounts | Account codes mapped clearly to the categories reported on the VAT return |
| VAT return reconciliation | A traceable link between the figures filed on each VAT return and the underlying ledger entries |
The common thread across all seven categories is traceability. An officer reviewing the file needs to move from a single figure on a filed VAT return back to the specific invoice, ledger entry and tax code that produced it, without gaps. Businesses that keep clean records for management reporting but never test whether those records reconcile to what was actually filed often discover the disconnect only once an audit notification arrives.
Accounting Software Requirements for the FTA Audit File
The FTA does not certify or approve specific accounting software products, but it does expect the software a VAT-registered business uses to produce the audit file on request, in a machine-readable format, without extensive manual reformatting. In practice, that means the system in use should be able to:
- Export the full general ledger and VAT-relevant transaction data for a specified period
- Maintain a consistent chart of accounts and tax code structure across periods
- Preserve an audit trail showing when entries were created, amended or reversed
- Reconcile, automatically or with minimal manual adjustment, to the figures already filed on the VAT return
Spreadsheet-based bookkeeping can technically satisfy the general VAT record-keeping rules, but it rarely satisfies the audit file requirement well, because spreadsheets do not preserve a system-generated audit trail and can be altered without a visible history. Businesses still relying on spreadsheets for VAT accounting typically end up reconstructing several categories of the audit file by hand once a request arrives, which extends the time needed to respond and increases the chance of reconciliation errors surfacing under review.

When and How the FTA Requests the Audit File
The FTA does not request the audit file as a routine matter for every registrant. It typically arises in three situations: a scheduled tax audit, a desk-based compliance review triggered by inconsistencies between a business’s VAT returns and its financial statements, or a targeted investigation following a referral, including through the FTA’s Raqeeb whistleblower programme.
When the FTA issues an audit notification, it specifies the tax periods under review and the documentation it expects the business to produce, within the timeframe stated in that notification. A business unable to produce a complete, traceable audit file within the stated window faces a longer and more intrusive process, because officers must then request individual documents piecemeal rather than reviewing one structured export.
Example: A trading company in the UAE receives an FTA audit notification covering the previous two tax periods. Its accounting software can export the general ledger and sales data within a day, but its supplier invoices are still filed on paper and matched to the ledger manually. The company spends most of the response window scanning and cross-referencing purchase invoices rather than reviewing its VAT position for genuine errors, a delay that is avoidable with audit-file-ready record keeping already in place before any notification lands.

Record Retention and the FTA’s Audit Window
The records that feed into an FTA Audit File must be kept for longer than many businesses assume, and the retention period differs by tax type.
| Tax type | Standard retention period | Extended retention |
|---|---|---|
| VAT (general) | 5 years from the end of the relevant tax period | +2 years if a refund claim is pending |
| VAT (real estate related records) | 10 years from the end of the relevant tax period | +2 years if a refund claim is pending |
| Corporate Tax | 7 years from the end of the relevant tax period | +2 years if a refund claim is pending |
The retention clock matters because it also defines how far back the FTA can reach. Under Federal Decree-Law No. 28 of 2021 on Tax Procedures, as amended by Federal Decree-Law No. 17 of 2025 (effective 1 January 2026), the FTA has a five-year window from the end of the relevant tax period to conduct a tax audit. A business that clears out records once its internal policy says the standard period is “done” can find itself unable to produce a compliant audit file for a period the FTA is still legally entitled to review.
The same amendment also updated the conditions under which a voluntary disclosure must be filed once an error is identified. Businesses that uncover a discrepancy while assembling an audit file should treat that discovery as a trigger to review their voluntary disclosure position under the current rules, not only correct the figure for the present period.
A further extension applies where a VAT refund claim is pending. Under Cabinet Decision No. 17 of 2026 (effective 1 April 2026), businesses with an open refund request must retain the underlying records for an additional two years beyond the standard retention period, specifically so the audit file stays complete while the refund position remains unresolved.
Federal Decree-Law No. 16 of 2025 (effective 1 January 2026) adds a related constraint on the input side: recoverable input tax must be claimed within five years of the relevant tax period. Records supporting older, unclaimed input tax fall outside both the recovery window and, in most cases, the practical need for continued retention, which makes them a reasonable candidate to flag during any records review tied to the audit file.

Common Mistakes That Make an FTA Audit File Non-Compliant
- Treating the audit file as something to assemble only after a notification arrives, rather than a standing capability of the accounting system
- Using a chart of accounts that does not map cleanly to the categories on the VAT return, which turns reconciliation into a manual exercise every time it is needed
- Keeping credit and debit notes in a separate log instead of linking each one back to the original tax invoice it corrects
- Discarding supporting records once the standard retention period looks like it has passed, without checking whether a pending refund claim extends it
- Assuming a bookkeeper’s monthly summary report satisfies the audit file requirement, when the FTA expects transaction-level detail
The obligation to maintain traceable, audit-ready records comes from the Tax Procedures Law framework and applies across tax types, not only VAT. Corporate Tax records carry their own 7-year retention period, but the same practical discipline, transaction-level detail that reconciles cleanly to what was filed, applies equally there.
