Corporate Tax Record-Keeping in the UAE

2025-11-20 · 4 min read · By Aureus Worldwide

Corporate tax compliance does not end when you file, it depends on records you can still produce years later. The Federal Tax Authority (FTA) can review a tax period long after the return is in, and the businesses that come through cleanly are those whose documents tie every figure back to source. Under Federal Decree-Law No. 47 on corporate tax, keeping proper records is a legal duty, not housekeeping. This guide sets out what to keep, for how long, and how to organise it so an audit is routine rather than painful.

Record-keeping is a statutory obligation

The law requires every taxable person to maintain records and documents that allow the FTA to verify their corporate tax position. The burden of proof sits with you: if you cannot evidence a deduction, relief or exemption, the FTA can disallow it regardless of whether it was genuine. In practice, your records are what defend every number on the return, so the quality of your documentation is the quality of your tax position.

Which records must you keep?

At a minimum, your corporate tax records should include:

• Financial statements for each tax period
• Accounting records, general ledger, trial balance, journals
• Tax computations showing every adjustment to accounting profit
• Invoices, contracts and agreements supporting income and expenses
• Bank statements and payment evidence
• Fixed asset registers and depreciation schedules
• Schedules for reliefs, exemptions and loss carry-forwards
• Transfer pricing documentation for related-party dealings

These records must be sufficient for the FTA to recompute your taxable income independently if it chooses to.

How long must you keep them?

Records must be retained for a minimum period set in the legislation, generally running for several years after the end of the relevant tax period. Certain situations extend that period:

Because the exact durations are set by the FTA and can be amended, confirm the current periods before disposing of anything, when in doubt, keep records longer rather than shorter.

Digital records are accepted, within conditions

The FTA permits electronic records, which nearly every business now relies on. To be acceptable, digital records must be:

• Accurate and complete, a faithful record of each transaction
• Secure, protected against loss, tampering or unauthorised change
• Readily retrievable, producible promptly when the FTA asks

Cloud accounting platforms paired with organised document storage make this far easier, but you still need sensible back-ups and access controls. The test is whether you can produce a usable, complete record on request.

Transfer pricing files deserve special attention

If your business transacts with related parties or connected persons, your record-keeping extends to transfer pricing documentation. Depending on your size and the nature of your dealings, you may need to maintain supporting files demonstrating that your prices are at arm's length. This is one of the areas the FTA scrutinises most closely, so keep contemporaneous evidence, agreements, benchmarking and the rationale for your pricing. Our transfer pricing guide explains the obligations in more depth.

Free zone companies have more to prove

A Qualifying Free Zone Person relies on records to defend the 0% rate. Beyond ordinary accounts, you should evidence:

• Adequate substance in the free zone, premises, people, activity
• Qualifying income correctly identified and separated
• Compliance with the de minimis and other conditions

Without this, the qualifying status is hard to sustain in a review. Substance and income evidence is not optional paperwork, it is the foundation of the rate you are claiming.

The audit trail is the whole point

Records exist so any figure on a return can be traced to its source. A strong corporate tax audit trail links:

1. The tax return to the tax computation
2. The computation to the financial statements
3. The financial statements to the underlying ledgers
4. Each ledger entry to its invoice, contract or document

If an FTA reviewer can follow that chain without friction, the audit is routine. Where the chain breaks is where assessments and penalties arise. The same discipline underpins VAT, see our VAT record-keeping guide for the parallel rules.

Common record-keeping failures

• Incomplete or unreconciled accounting records
• Missing supporting documents for claimed deductions
• No transfer pricing file where one is required
• Free zone businesses lacking substance and qualifying-income evidence
• Disposing of records before the retention period ends
• Records that cannot be retrieved quickly in an audit

Build it into your routine

The businesses with the least audit stress file documents as transactions happen, reconcile monthly, and store everything in one organised, retrievable system tied to each tax period. Because retention periods and certain rules are set by the FTA and can change, confirm the current requirements before disposing of records or relying on a particular treatment.
