FTA Tax Audit Document Checklist
To be audit-ready, keep a complete, organised set of records: all issued and received tax invoices, filed VAT and corporate tax returns with their workings, audited financial statements, the general ledger and trial balance, bank statements reconciled to the accounts, customer and supplier contracts, import and export or customs documents, and transfer pricing documentation where the rules apply to you. Minimum retention periods differ by record type, broadly seven years for corporate tax records, five years for general VAT records, and up to fifteen years for real-estate-related records, and they apply even to exempt persons, so having filed a nil return is not a reason to discard the file. The records also have to be retrievable in a usable form, not just stored somewhere; a backup nobody can restore does not count, and a missing document during an audit is a weakness the auditor will note immediately.

What to have ready
These are the documents an auditor will almost always request in the first round, because they form the backbone of any VAT or corporate tax review. Missing even one of them slows the audit down and signals that your record-keeping is not as tight as your filings suggest. Having them assembled and current, rather than reconstructed after a notice arrives, is the difference between a fast audit and a drawn-out one.
- All tax invoices issued and received, matching exactly what was reported in each return.
- Filed VAT and corporate tax returns together with the workings behind each figure.
- Audited financial statements, the general ledger and the trial balance for the period.
- Bank statements reconciled to the accounts, not just held as a separate file.
- A one-page bridge showing how accounting profit ties to the figure actually filed.
The evidence behind the numbers
The real question an auditor is testing is whether your filings match commercial reality, and these are the documents that prove, or fail to prove, that they do. A contract without a matching invoice, or an invoice without a matching contract, is exactly the kind of gap an audit is designed to surface. Organising this evidence by tax period, rather than by document type, is what makes it possible to answer a request quickly.
- Customer and supplier contracts and agreements that support the substance of each transaction.
- Import declarations and export or customs documents for cross-border supplies.
- Transfer pricing files where the rules apply, kept current rather than assembled on request.
- Evidence for any unusual transaction, such as a disposal or a related-party deal, created at the time, not after.
- Everything organised by tax period for fast retrieval, not scattered across systems and inboxes.
How long records must be kept
An audit can reach back across several earlier tax periods, so your archive has to survive far longer than the filing cycle itself. UAE law sets minimum retention periods that differ by record type, and they apply to exempt persons just as much as taxable ones: having owed no tax in a period is not a reason to bin the file. Retention also means more than existence, since the records must be retrievable in a form that lets the FTA readily verify the figures, not buried in a format nobody can open anymore.
- Corporate tax records: generally seven years after the end of the relevant tax period.
- VAT records generally: five years from the end of the tax period.
- Real-estate-related records: up to fifteen years, reflecting how long property transactions can remain relevant.
- A backup that cannot actually be restored, or sits on a former employee's laptop, does not satisfy the retention requirement.
Build the file before you need it
Five business days is rarely enough time to build an audit-ready archive from scratch; it is only enough time to open one. The practical answer is to treat the audit file as part of the monthly close rather than a separate project, so a notice changes who reads the folder and nothing else. Businesses that do this consistently tend to have shorter, calmer audits, because nothing has to be reconstructed under pressure.
- Reconcile every return to the ledger in the period you file it, and keep the reconciliation with the return.
- Index the archive by tax period, one folder per return, covering invoices, ledgers, bank statements and contracts.
- Document unusual transactions at the time they happen, while the people who handled them still work for you.
- Test retrieval once a year: pick an old period and see how quickly you could actually produce its file.

Frequently Asked Questions
For finance teams assembling an audit-ready file before a notice, not after one.
How long must I keep records?
It depends on the record type: generally seven years for corporate tax records, five years for general VAT records, and up to fifteen years for real-estate-related records. The FTA can request records anywhere within the applicable period during an audit.
What is the most commonly missing document?
Valid tax invoices and the reconciliations that tie your returns back to the ledger. Gaps here are exactly what auditors seize on, because they are the direct evidence behind every figure filed.
Do I need transfer pricing files for an audit?
If the transfer pricing rules apply to you, yes. The FTA can request this documentation on short notice, so it needs to be kept current rather than assembled only once a request arrives.
Can Exiloz build our audit file?
Yes. We assemble and organise an audit-ready archive, indexed by tax period, so any FTA document request can be answered quickly and completely rather than reconstructed under pressure.
Do exempt businesses still need to keep records?
Yes. Retention obligations apply to exempt persons as well as taxable ones. Having filed a nil or exempt return does not remove the requirement to keep the underlying records for the applicable period.
Should records be kept digitally or on paper?
Either can work, but the format has to be genuinely retrievable. A digital archive that nobody can restore, or paper stored somewhere inaccessible, fails the same test: the FTA must be able to readily verify the figures from what you produce.
What happens if a document is missing during an audit?
It becomes a specific weakness the auditor notes and often probes further, because it raises the question of what else might be missing. Where possible, flag genuine gaps proactively rather than let the auditor discover them.
How often should we test our audit-readiness?
At least once a year. Pick an older tax period at random and see how quickly your team could actually produce a complete file for it. That exercise usually reveals gaps well before an audit notice does.
