What Documents Do VAT Auditors Request in UAE?
Complete Guide to FTA Audit Documentation Requirements & Compliance Checklist
When the Federal Tax Authority initiates a VAT audit of your business in the UAE, being prepared with the right documentation can mean the difference between a smooth process and costly penalties. Understanding exactly what documents VAT auditors request and how to organize them is crucial for every business operating in Dubai and across the Emirates. At One Desk Solution, we've guided hundreds of businesses through FTA audits, and we know precisely what documentation auditors expect to see.
Understanding FTA Documentation Requirements
The Federal Tax Authority has established comprehensive documentation requirements that all VAT-registered businesses must follow. These requirements aren't merely suggestions—they're legal obligations backed by significant penalties for non-compliance. The UAE VAT law mandates that businesses maintain all tax-related records for a minimum of five years from the end of the tax period to which they relate.
📊 Verification Focus Areas
- Correct VAT calculation on sales
- Legitimate input tax claims
- Proper supply classification
- Accurate VAT returns
- Compliant accounting systems
⏰ Retention Period
5 Years Minimum
All VAT-related documents must be retained for five years from the end of the relevant tax period.
⚖️ Legal Burden
The burden of proof lies with the taxpayer. Without proper documentation, legitimate transactions may be disallowed by auditors.
⚠️ Critical Documentation Principle
Your documentation serves as evidence supporting every figure in your VAT returns. Missing or incomplete documents can lead to input tax disallowance, output tax reassessments, and significant penalties—even for legitimate business transactions.
Core Business Registration Documents
VAT auditors begin by requesting fundamental business registration documents to establish your legal status and VAT registration credentials.
| Document Type | Purpose | What Auditors Verify |
|---|---|---|
| Trade License | Legal business authority | Validity, alignment with business activities in VAT returns |
| VAT Registration Certificate | VAT registration proof | Active status, registration date, TRN accuracy |
| Establishment Card | Business identity | Matching details with VAT registration |
| Memorandum of Association | Company structure | Business nature and ownership understanding |
| Immigration Establishment Card | Employee authorization | Verification of business operations scale |
Key Compliance Point
Your trade license must be current and reflect actual business activities. Auditors compare activities listed on your license with the nature of supplies shown in VAT records. Discrepancies can raise red flags about unreported income or unauthorized activities.
Tax Invoice Documentation
Tax invoices form the backbone of VAT documentation and are the most frequently requested items during any VAT audit.
Mandatory Tax Invoice Elements
- The words "Tax Invoice" clearly stated
- Unique sequential invoice number
- Your business name, address, and TRN
- Customer's name and address
- Date of supply and invoice issue date
- Description of goods/services supplied
- Quantity and unit price
- Total amount excluding VAT
- VAT rate applied (5% standard)
- VAT amount in UAE Dirhams
- Total amount including VAT
📤 Issued Tax Invoices
Auditors request complete copies of all tax invoices issued during the audit period to verify output tax calculations and compliance with UAE invoicing requirements.
📥 Received Tax Invoices
Auditors examine all supplier invoices supporting your input tax claims, verifying that suppliers are VAT-registered, invoices are compliant, and supplies relate to your business activities.
Simplified Tax Invoices
For supplies under AED 10,000, reduced requirements apply. However, basic compliance elements must still be present. Learn more about invoice requirements in our FTA Inspection Checklist.
Purchase and Sales Records
Sales Documentation Package
| Document Category | Specific Items Requested | Audit Purpose |
|---|---|---|
| Sales Invoices | All tax invoices issued | Verify output tax calculation |
| Credit Notes | Issued credit and debit notes | Confirm VAT adjustments |
| Sales Agreements | Contracts with customers | Understand transaction terms |
| Export Documentation | Customs declarations, shipping docs | Validate zero-rating claims |
| Sales Register | Comprehensive sales listing | Cross-check against VAT returns |
🚨 Export Documentation Requirements
For businesses claiming zero-rating on exports, documentation requirements are particularly stringent. Auditors need to see:
- Proof that goods physically left the UAE
- Evidence of supply to a recipient outside UAE
- Documentation showing customer's overseas location
- Complete customs export declarations
Purchase Documentation Package
Purchase records should demonstrate that input tax claims are legitimate and relate to taxable business activities:
- All supplier invoices for claimed input tax
- Purchase orders showing business intent
- Goods received notes confirming receipt
- Payment records proving transactions occurred
- Import documentation for goods brought into UAE
Financial and Accounting Records
VAT auditors request comprehensive financial records to trace transactions from source documents through to VAT returns.
General Ledger
Forms the foundation of financial record-keeping. Auditors use this to verify VAT amounts in returns match accounting system totals.
Trial Balance
Provides a snapshot of all account balances at period end. Auditors compare against VAT returns for consistency.
Bank Statements & Reconciliations
Critical for verifying that reported sales and purchases actually occurred. Auditors trace transactions from invoices to bank deposits.
Cash Books & Petty Cash Records
Should record all cash transactions with sufficient detail and supporting receipts for all disbursements.
Journal Entries
Particularly adjusting entries receive special attention. Auditors want to understand why adjustments were made and VAT handling.
VAT-Specific Records and Returns
| VAT Return Element | Supporting Documentation Required | What Auditors Verify |
|---|---|---|
| Standard-rated supplies (Box 1) | Sales invoices, contracts, revenue recognition schedules | Accuracy of output tax calculation |
| Zero-rated supplies (Box 2) | Export evidence, shipping documents, customer declarations | Eligibility for zero-rating |
| Exempt supplies (Box 3) | Transaction details, legal basis for exemption | Proper classification |
| Standard-rated expenses (Box 6) | Purchase invoices, import declarations | Legitimacy of input tax claims |
| VAT due for period (Box 9) | Complete reconciliation workings | Mathematical accuracy |
VAT Account & Reconciliations
Your VAT account should maintain a running balance showing VAT collected from customers, VAT paid to suppliers, amounts paid to FTA, and any refunds received. Monthly reconciliations between VAT returns and accounting records are essential and identify differences with explanations for any discrepancies.
Import and Export Documentation
📦 Import Documentation
- Customs declarations showing VAT paid
- Import permits and licenses
- Bills of lading/airway bills
- Commercial invoices from suppliers
- Payment evidence for customs VAT
📤 Export Documentation
- Customs export declarations
- Commercial invoices to overseas customers
- Transport documents proving shipping
- Proof of payment from customers
- Customer declarations confirming location
⚠️ Common Export Documentation Issue
Missing or incomplete export documentation is one of the most common reasons for denial of zero-rating claims. Even if goods were genuinely exported, without proper documentation, the FTA may reclassify the supply as standard-rated and assess additional VAT plus penalties.
Asset and Inventory Records
🏢 Fixed Asset Documentation
Auditors request your fixed asset register showing all capital assets, acquisition dates, costs including VAT, depreciation schedules, and disposal details. For significant purchases, they examine whether input tax was correctly claimed and whether capital goods scheme adjustments are required.
📊 Inventory Records
Your inventory records should show quantities and values at the beginning and end of each tax period. Auditors use these to verify sales completeness and identify discrepancies between physical counts and accounting records.
Special Transaction Records
🏠 Real Estate Transactions
- Sale and purchase agreements
- Property title documents
- Construction contracts
- Rental agreements
- Mixed-use allocation calculations
🏦 Financial Services
- Detailed service descriptions
- Exempt vs taxable classification support
- Partial exemption calculations
- Fee structures and billing records
Digital Records Requirements
The FTA accepts electronic records if they are accessible, readable, protected from alteration, backed up, and exportable to standard formats. Auditors may request direct access to your accounting software to verify audit trails and transaction recording.
Documentation Organization Best Practices
Effective Filing Systems
- Organize documents chronologically by tax period
- Separate documents by category (sales, purchases, etc.)
- Maintain both digital and physical copies
- Use clear file naming conventions
- Create a master index showing document locations
- Designate responsibility for document maintenance
Retention Requirements
5 Years Minimum: UAE VAT law requires maintaining all VAT-related records for five years from the end of the relevant tax period.
Extended Retention
For ongoing disputes or appeals, retain all relevant documents until full resolution. For capital assets, maintain acquisition documentation for the asset's entire life plus five years.
Common Documentation Deficiencies
| Documentation Issue | Consequence | Prevention Strategy |
|---|---|---|
| Missing tax invoices | Input tax disallowed | Implement strict invoice collection procedures |
| Non-compliant invoice format | Output tax disputes | Use standardized invoice templates |
| Incomplete export documentation | Loss of zero-rating | Create export documentation checklist |
| Poor expense documentation | Input tax recovery denied | Require detailed expense receipts with business justification |
| Inconsistent record-keeping | Extended audit, increased scrutiny | Regular internal audits and reconciliations |
🚨 Missing Documentation Consequences
If you can't produce required documents, the FTA may disallow related input tax claims and assess additional output tax based on estimates. The burden of proof lies with the taxpayer—maintaining complete records is non-negotiable.

2. Are digital/electronic records acceptable to FTA auditors?

Auditors may request direct access to your accounting software to verify audit trails.
