FTA Audit File Guide in the UAE

BBiz Growth ConsultancyOctober 22, 2026

Businesses registered for VAT in the UAE need to keep their tax records accurate and ready for review. During a tax audit, the Federal Tax Authority (FTA) may ask a business to provide accounting records, invoices and other information to check whether its tax returns are correct. Having these records organised can make it easier to respond to requests and identify errors before they become bigger problems. One important part of this process is the FTA Audit File (FAF). It is a standard electronic file containing accounting and transaction data that helps the FTA review a business's tax records. If you operate a VAT-registered business, understanding how the FAF works, what information it contains and how to prepare for an audit can help you manage your tax responsibilities more effectively.

What Is the FTA Audit File (FAF) in the UAE?

The FTA Audit File, commonly known as FAF, is a structured file generated from a business's accounting system. It contains information about the company, customers, suppliers, sales, purchases and other accounting transactions. The FTA uses this information to check the accuracy of tax declarations and understand how transactions have been recorded. The FAF is different from a VAT return. A VAT return summarises the VAT a business owes or can recover for a particular tax period, while the FAF provides more detailed transaction-level information behind those figures. Businesses should also understand that the FAF does not replace invoices, accounting records or other supporting documents that may be requested during an audit.

When Does a UAE Business Need to Provide a FAF?

The FTA may conduct a tax audit to check whether a business has followed the applicable tax rules and reported its transactions correctly. If the authority requests a FAF, the business should be able to generate the relevant information for the period specified in the request. Keeping your accounting system organised throughout the year makes this process easier.

You should not wait until an audit notice arrives to check whether your records are complete. Review your accounting software, VAT returns and supporting documents regularly. Although the FAF is designed to help businesses respond to audit requests, the exact information required will depend on the nature of the audit and the FTA's instructions.

What Information Is Included in an FTA Audit File?

A FAF contains several categories of information that help the FTA understand a business's transactions. The exact fields depend on the applicable file specification and the type of tax file being generated.

The main information may include:

  • Company details: Business name, Tax Registration Number (TRN) and relevant reporting period information.

  • Customer and supplier records: Names, locations and applicable tax registration details.

  • Sales and purchase transactions: Invoice numbers, dates, transaction values and VAT amounts.

  • Accounting information: General ledger entries, tax codes and relevant debit or credit amounts.

  • Payment and product details: Information required by the applicable FAF structure.

Ensure your accounting records match your invoices. Missing details, incorrect tax codes or inconsistent figures can cause errors.

How to Choose Accounting Software for FAF Generation

Preparing a FAF manually can take time, particularly when a business processes a large number of sales and purchase transactions. Suitable tax accounting software can collect the relevant information and generate the file in the required structure. The UAE FTA's published software requirements describe the FAF format and the information that the system should capture.

Before choosing or upgrading your accounting software, check whether it supports the relevant UAE VAT audit file requirements. Ask your provider whether it can generate the required file for a selected period, handle customer and supplier records, record tax codes correctly and export transaction data in the prescribed format. Do not assume that software capable of preparing VAT returns can automatically produce a compliant FAF.

How to Maintain Accurate Records for an FTA Audit

Your FAF is only as reliable as the accounting information behind it. If sales invoices are missing, purchase transactions are recorded incorrectly or VAT codes are applied inconsistently, the generated file may contain errors. Regular checks can help you find these issues before the FTA requests information.

Good record keeping practices include:

  • Reconciling sales and purchase records with your VAT returns.

  • Checking that invoices and credit notes are recorded correctly.

  • Reviewing VAT treatment for local, imported and other relevant transactions.

  • Keeping electronic copies of supporting documents in an organised system.

  • Retaining tax records for the period required under UAE law.

Protect your financial records and back up your data. If you find an error, consult your accountant or tax adviser about the necessary corrections.

Businesses that need help reviewing their financial records can explore professional auditing services to understand the scope of support available.

How to Prepare an FTA Audit File Before an Audit Request

When the FTA requests information, read the notice carefully and confirm the reporting period, documents and submission deadline. Generate the FAF for the requested period, review the output and make sure the relevant supporting records are available. If you notice missing information or differences between the file and your tax returns, investigate them promptly rather than submitting figures you cannot explain.

A FAF may not be the only document required during an audit. Depending on the request, you may also need to provide invoices, general ledger reports, VAT workings, bank records or other supporting documents. Keep communication with your accountant or tax adviser clear and respond within the deadline specified by the authority.
