An FTA VAT audit starts with at least 5 business days' written notice and reaches up to five years of records. Preparation is not about hoping the Federal Tax Authority picks someone else — it is about your VAT returns reconciling to your ledgers, your bank statements and your invoices before the notice lands, because the expensive failures are all self-inflicted.
TL;DR
- The FTA must notify you at least 5 business days before an audit, and can examine records up to 5 years after the end of the relevant tax period (Federal Decree-Law No. 28 of 2022, Tax Procedures Law).
- Keeping no required records costs AED 10,000 first time, AED 20,000 on repeat; failing to facilitate an audit costs AED 20,000.
- Late VAT returns cost AED 1,000 first time, AED 2,000 on repeat within 24 months; late payment adds 14% per annum, charged monthly.
- A voluntary disclosure filed BEFORE an audit notice carries a 1%-per-month penalty on the tax difference — after an audit notice, a 15% fixed penalty applies.
What triggers a VAT audit
The FTA runs risk-based selection — no published formula — but the patterns that historically draw attention are consistent: refund claims, VAT returns that swing wildly between periods, input tax claims on exempt activity, gaps between declared revenue and bank credits, and non-filing. A first audit is often triggered by the business's own numbers, not a complaint.
The auditor's legal powers
Under the Tax Procedures Law the FTA can enter your business premises during working hours, inspect commercial records and goods, take copies and extracts, sample inventory, and seal records or devices where evidence could disappear. Refusing entry, hiding records or otherwise failing to facilitate the audit is itself a penalised violation.
The document checklist
Six categories cover nearly every request in practice:
- Ledgers and accounting records — the books your returns were built from.
- Sales invoices and tax invoices — issued in the legally required form and content.
- Bank statements — every account, full period.
- Purchase invoices and credit notes — supporting every input VAT claim.
- Customs and import documentation — imports are a classic mismatch point.
- VAT returns and workings — with the reconciliations behind the filed figures.
Five steps to audit readiness
- Reconcile returns to the ledger to the bank, quarterly. Most audit pain is arithmetic drift: returns that never matched the books they supposedly came from.
- Check invoice compliance. A missing or malformed tax invoice is AED 2,500 per detected case — and multiplies fast across a quarter.
- Fix errors through voluntary disclosure, early. Disclosed before any audit notification, errors cost a 1%-per-month penalty on the tax difference; after an audit notice, a 15% fixed penalty applies. The window closes the day the notice arrives.
- Assign one owner for the audit response. A named contact who controls document production prevents the accidental contradictions that extend audits.
- Keep records in order for 5+ years. The obligation does not end when the return is filed.

Penalties per Cabinet Decision No. 40 of 2017 as amended (including Cabinet Decision No. 129 of 2025, effective 14 April 2026) — verify current amounts on the FTA's published penalty tables before relying on them.
What happens after the audit
The auditor issues findings; if the FTA assesses additional tax, payment falls due 20 business days from receiving the assessment — late payment starts the 14% clock. You can object through the Tax Dispute Resolution Committee within the statutory window, but objections do not pause the late-payment penalty while the dispute runs, so the arithmetic of contesting versus paying deserves honest modelling.
Businesses running VAT in-house should pressure-test their setup with the VAT filing service or compare provider models in the VAT consultants guide. Online sellers face a longer checklist — the e-commerce VAT compliance guide covers marketplace and e-invoicing angles.

FAQ
How much notice does the FTA give before a VAT audit?
At least 5 business days' written notice, under the Tax Procedures Law — though in defined circumstances the FTA can audit without prior notice.
How far back can a VAT audit go?
The FTA can examine records up to 5 years after the end of the relevant tax period — keep complete records well beyond that horizon.
What is the penalty for refusing an FTA audit?
Failing to facilitate a tax audit carries an AED 20,000 penalty, separate from any tax assessed on the underlying returns.
Should I file a voluntary disclosure before an audit?
If you know of errors, yes: disclosed before an audit notification, the penalty is 1% per month on the tax difference; after an audit notice, a 15% fixed penalty applies.
Can the FTA visit my premises unannounced?
The law requires advance notice in the ordinary case, but permits exceptions — records should be maintained as if a visit could happen at any time.
How long do I have to pay additional VAT assessed after an audit?
20 business days from receiving the assessment; unpaid amounts then attract 14% per annum, charged monthly.
What records should a UAE business keep for VAT?
Accounting books, tax invoices, credit notes, bank statements, customs documents and filed returns — organized so any quarter can be reconstructed without archaeology.
Does objecting to an audit assessment stop the penalties?
No — late-payment penalties continue to accrue while a dispute is pending, which is why the payment-versus-dispute decision deserves a costed comparison.
