## What is an FTA audit document?

An FTA audit document is any record the Federal Tax Authority (FTA) may request when it examines a business's tax affairs. These documents prove that a company has calculated, reported, and paid VAT or corporate tax correctly. Keeping the right records in good order is a legal obligation under UAE tax law, not just a best practice.

Understanding which records qualify as an FTA audit document is essential for [FTA compliance in the UAE](https://einvoicedirect.ae/fta-compliance-uae). This article lists every document category, explains retention rules, and gives you a practical checklist so nothing is missing when the FTA comes calling.

## Legal basis for document retention in the UAE

Two main laws set the rules for keeping tax records in the UAE.

- **Federal Decree-Law 8 of 2017** (VAT Law) requires every taxable person to maintain records that allow the FTA to verify VAT returns.

- **Federal Decree-Law 47 of 2022** (Corporate Tax Law) imposes similar obligations for corporate tax purposes, covering income, expenses, assets, and liabilities.

Federal Decree-Laws 16 and 17 of 2024 amended the VAT and tax procedures frameworks respectively. Ministerial Decisions 243 and 244 of 2025 added further detail around e-invoicing and transaction controls. Together, these laws mean that every UAE business registered for VAT or corporate tax must keep supporting documents for a minimum period and produce them on request.

### Retention periods

The general rule is 5 years from the end of the relevant tax period. For real estate and capital assets, the period extends to 15 years. The table below summarises the key retention windows.

| Document category | Minimum retention period | Legal reference |
| --- | --- | --- |
| VAT invoices (sales and purchase) | 5 years | Federal Decree-Law 8 of 2017 |
| VAT returns and supporting schedules | 5 years | Federal Decree-Law 8 of 2017 |
| Corporate tax returns and computations | 5 years | Federal Decree-Law 47 of 2022 |
| General ledger and journal entries | 5 years | Tax Procedures Law |
| Bank statements | 5 years | Tax Procedures Law |
| Contracts and agreements | 5 years (15 years if related to real estate) | Tax Procedures Law |
| Capital asset records | 15 years | Federal Decree-Law 8 of 2017 |
| Import and export customs declarations | 5 years | Tax Procedures Law |

## How the FTA requests documents during an audit

The FTA sends a written notification at least 5 business days before an audit begins. That notice lists the tax periods under review and the broad document categories required. During the audit itself, auditors may request additional records verbally or in writing.

You are legally required to cooperate. Refusing to provide a requested FTA audit document, or providing false records, can result in penalties under Cabinet Decision 106 of 2025. Fines range from AED 2,500 to AED 50,000 per violation, depending on severity and repetition.

Knowing [what triggers an FTA audit in the UAE](https://einvoicedirect.ae/fta-compliance-uae/what-triggers-fta-audit-uae) can help you stay prepared before a notification arrives.

## Organising your FTA audit documents: practical tips

Having the right documents is only half the battle. The FTA expects records to be accessible and logically organised. Follow these guidelines.

### Digital storage best practices

- Store files in a cloud system with access controls and an audit trail.

- Name folders by tax period, then by document type (e.g., 2024-Q1 > Sales Invoices).

- Keep PDF copies of every invoice alongside the accounting-system export.

- Back up data at least weekly to a separate location.

### Reconciliation routines

Run a monthly reconciliation between your VAT return figures and your general ledger. This single habit catches most discrepancies before they become audit findings. For corporate tax, reconcile your accounting profit to taxable income at each quarter end.

## Common document gaps that cause problems

| Gap | Risk | Fix |
| --- | --- | --- |
| Missing purchase invoices | Input tax disallowed, additional VAT plus penalties | Request duplicates from suppliers immediately; reconcile monthly |
| No proof of export for zero-rated supplies | FTA reclassifies supply as standard-rated at 5% | Collect customs exit certificates and shipping documents at time of dispatch |
| Incomplete transfer pricing file | Adjustment to arm's-length pricing, corporate tax reassessment | Prepare documentation contemporaneously, not after year-end |
| Gaps in sequential invoice numbering | Suspicion of unreported sales | Use accounting software that auto-numbers invoices; investigate and document any voided numbers |
| Bank statements not matching declared revenue | Triggers deeper investigation | Reconcile bank deposits to sales ledger monthly |

If the FTA identifies discrepancies, it may issue a tax assessment. Learn what happens next in the [FTA tax assessment process](https://einvoicedirect.ae/fta-compliance-uae/fta-tax-assessment-process) overview.

## E-invoicing and future document requirements

The UAE is rolling out mandatory e-invoicing under a Peppol 5-corner model called Decentralized Continuous Transaction Control and Exchange (DCTCE). The invoice format is PINT AE, based on Universal Business Language (UBL) 2.1.

Key dates to note:

- **Q2 2026:** Pilot phase begins.

- **October 30, 2026:** Businesses with revenue of AED 50M or more must appoint an Accredited Service Provider (ASP).

- **January 1, 2027:** Phase 1 mandatory go-live for large businesses.

- **July 1, 2027:** SMEs (under AED 50M revenue) go live.

- **October 1, 2027:** Government entities go live.

Once e-invoicing is mandatory, every business-to-business (B2B) and business-to-government (B2G) invoice will flow through the DCTCE network. This means the FTA will have near-real-time access to transaction data. Maintaining clean, structured invoice records now will make the transition smoother and reduce audit risk later.

## What happens if documents are missing during an audit

The FTA can take several actions when a business fails to produce requested records.

- **Estimated assessment:** The FTA calculates tax liability based on available information, which usually results in a higher figure than actual liability.

- **Administrative penalties:** Under Cabinet Decision 106 of 2025, fines of AED 2,500 to AED 50,000 apply per violation for failure to maintain or produce records.

- **Escalation to investigation:** Persistent non-compliance or suspected fraud can escalate the matter beyond a standard audit. See the [FTA investigation vs audit](https://einvoicedirect.ae/fta-compliance-uae/fta-investigation-vs-audit) comparison for details on how these differ.

After the audit concludes, the FTA issues its findings. The [post audit procedures in the UAE](https://einvoicedirect.ae/fta-compliance-uae/post-audit-procedures-uae) page explains your options for objection and appeal.

## Frequently asked questions

### What documents does the FTA ask for during a tax audit?

The FTA typically requests VAT returns, tax invoices (sales and purchases), corporate tax computations, financial statements, bank statements, contracts, customs declarations, and the general ledger. The exact list depends on the tax periods and taxes under review. Keeping all records organised by period and category speeds up the process.

### How long must I keep tax records in the UAE?

The general retention period is 5 years from the end of the relevant tax period. Records related to real estate or capital assets must be kept for 15 years. These rules apply to both VAT and corporate tax documents under the UAE Tax Procedures Law.

### What happens if I cannot provide documents during an FTA audit?

The FTA may issue an estimated tax assessment based on available data, which often results in a higher liability. Administrative penalties under Cabinet Decision 106 of 2025 range from AED 2,500 to AED 50,000 per violation. Repeated failures can escalate the matter to a formal investigation.

### Does the FTA accept digital copies of invoices?

Yes. The FTA accepts electronic records as long as they are accurate, complete, and accessible on request. Digital files should be stored with proper backup and access controls. Once mandatory e-invoicing begins in 2027, structured digital invoices in PINT AE format will become the standard.

### How far back can the FTA audit my business?

The FTA can generally audit tax periods going back 5 years. In cases of fraud or deliberate tax evasion, there is no statutory time limit. This is why maintaining records for at least 5 years after each tax period ends is a legal requirement, not optional.

### Do I need to keep payroll records for an FTA audit?

Payroll records are relevant when they affect taxable income under corporate tax, such as salary expenses, end-of-service benefits, or benefits-in-kind. The FTA may request employee contracts and salary schedules to verify deductions claimed in corporate tax computations.

### What is the penalty for not maintaining proper tax records in the UAE?

Under Cabinet Decision 106 of 2025, penalties for failing to maintain or produce tax records range from AED 2,500 to AED 50,000 per violation. The exact amount depends on the nature of the breach and whether it is a first or repeated offence.
