Audit trail: what it means for UAE businesses.

What audit trail means

An audit trail is the chain of evidence that lets anyone follow a number in the accounts back to the transaction that created it, and see who entered or changed it and when. It runs from the return or financial statements, through the ledger and journals, to the invoice, contract or bank record behind each entry.

UAE tax law is built around being able to follow that chain. The Tax Procedures Executive Regulation says records must be kept in a way that lets the Federal Tax Authority verify tax obligations, and where copies replace originals they must be identical and reproducible on request. The FTA's requirements for tax accounting software list adequate audit trails, internal controls and secure archiving among their principles, alongside the ability to produce an FTA Audit File. During a tax audit, the FTA may take original records or copies.

For an SME, a working audit trail is what turns an FTA audit or a statutory audit into a routine exercise. The trail is broken by deleted invoices, edited entries after a return is filed, shared logins and missing attachments. Corrections should be made with credit notes and reversing entries, never by overwriting, so both the error and the fix are visible.

How it works

• Every entry carries a date, a reference to its source document and the user who posted it.
• Changes are made by new, dated entries such as reversals, tax credit notes and adjusting journals, so the original remains visible.
• Accounting software keeps a change log, individual user logins and access rights, as the FTA's software requirements expect.
• Electronic copies must match the originals and be reproducible in readable form when the FTA asks (Tax Procedures Executive Regulation, Article 4).
• The trail must survive for the whole retention period: seven years after the tax period for Corporate Tax records.

Worked example

A Dubai software reseller finds that a March 2026 invoice was overcharged after the VAT return was filed. Instead of editing the invoice, it issues a tax credit note in May 2026.

Original invoice value before VAT	AED 25,000
Output VAT on the original invoice	AED 1,250
Tax credit note value before VAT	AED 3,000
Output VAT reduced by the credit note	AED 150
Net output VAT on the sale after the correction	AED 1,100

The filed return, the original invoice and the credit note all stay visible, so the FTA can see what happened and why.

Common mistakes

• Editing or deleting an invoice after the VAT return for that period has been filed.
• Sharing one login across the finance team, so the system cannot show who made an entry.
• Keeping scanned receipts separately from the ledger with no reference linking them to the entries they support.

The law

• Cabinet Decision No. 74 of 2023, Executive Regulation of the Tax Procedures Law, Article 2 (Keeping Records) and Article 4 (Method of Keeping Accounting Records and Commercial Books)
• Federal Decree-Law No. 28 of 2022 on Tax Procedures, as amended, Article 16 (The Right of the Authority to Perform a Tax Audit) and Article 17 (original records or copies during the Tax Audit)
• Federal Decree-Law No. 47 of 2022, as amended, Article 56 (Record Keeping)

Frequently asked questions

Does the FTA require a particular accounting software?

No single product is required. The FTA publishes requirements for tax accounting software, covering audit trails, internal controls, archiving and the FTA Audit File, and good software should meet them. What the law requires is that records let the FTA verify your tax position.

How do we correct a mistake without breaking the audit trail?

Post a new, dated correction: a tax credit note for a sales invoice, a reversing journal for a posting error, or a voluntary disclosure where a filed return needs correcting. Keep a note of why the correction was made.
