Record Keeping After VAT Registration in the UAE

The record set starts with transaction documents: all tax invoices issued, all tax invoices and simplified invoices received, credit and debit notes, and receipts. These evidence the output tax charged and the input tax claimed — the two pillars of every return.

Then the VAT account and ledgers: the sales and purchase ledgers, the VAT control account, import schedules and customs declarations, reverse-charge workings, and apportionment calculations. These show how the documents became the return figures.

Then the supporting layer: contracts evidencing the VAT treatment of supplies, the threshold workings from registration, correspondence with the FTA, voluntary disclosures, and the return filings themselves with their reconciliations. An FTA review can ask for any of it; the complete file answers everything.

The statutory retention period is generally five years from the end of the relevant tax period — and longer where the law or an ongoing enquiry requires it. The clock runs per period, so records are not disposable in bulk at a single date; each period's file has its own expiry.

Deregistration does not end the obligation. Former registrants must retain their records for the statutory period after deregistration — the FTA can review closed registrations, and the records are the only defence.

Diarise retention expiries rather than purging by habit. A rolling retention schedule — each period's file marked with its earliest disposal date — prevents both premature destruction and indefinite accumulation. When in doubt, keep: storage is cheap, reconstruction is not.

Electronic records are fully acceptable, provided they are complete, legible, and retrievable — and provided the underlying data has not been altered. Scanned invoices must be clear and complete; accounting data must be exportable; email approvals that form part of the VAT decision should be archived, not left in inboxes.

The test is practical: can the business produce a complete period file — return, reconciliations, supporting documents — within a reasonable time of an FTA request? If producing it takes weeks of reconstruction, the records fail the accessibility test whatever their theoretical completeness.

Protect the archive: backups independent of the live system, access controls on who can alter historical data, and a prohibition on purging accounting history. The VAT archive is a legal record, not just an IT convenience — treat its integrity accordingly.

The organising principle is the tax period: each period gets a file containing the filed return, the reconciliations tying it to the ledgers, the supporting schedules (imports, reverse charge, apportionment), and the key source documents or their index. An auditor opening any period's file should find the whole story.

Maintain a master index: every period, its filing date and reference, its payment or refund, and the file location. The index is the map of the archive — without it, even complete records are just a pile.

Review the archive annually: are all periods filed and present, are the reconciliations complete, is anything missing? The annual review catches the missing credit note file or the unreconciled quarter while it is still fixable — not during an FTA visit years later.

Verifications follow patterns, and certain records are requested almost every time. Tax invoices — issued and received — top the list: the FTA samples them against the return figures, checking the TRN, the rate, and the arithmetic. Missing or defective invoices in the sample extrapolate into assessments, so the invoice population must be complete and sequential.

Next come the reconciliations: sales ledger to output tax, purchase ledger to input tax, and the VAT account tying the two to the filed returns. Returns that reconcile cleanly to the ledgers pass quickly; returns that don't trigger the deep dive. The reconciliation file is the single highest-value document in the archive.

Then the judgement areas: apportionment workings for mixed businesses, reverse-charge schedules for importers, proof of export for zero-rated supplies, and the contracts supporting unusual VAT treatments. These are the records businesses most often lack — because they require someone to have thought about the VAT treatment at the time, not afterwards. Build them contemporaneously: the contract filed with its VAT analysis, the export with its proof, the apportionment with its method note. The FTA asks for these precisely because they separate organised registrants from the rest.
