UAE VAT in 2026: What Changed and How to Prepare for an FTA Audit

VAT audits are rarely about “big surprises.” They’re about evidence: can you prove the VAT treatment you applied? In 2026, businesses should treat VAT compliance as an operational system—not a quarterly panic.

What’s new to pay attention to in 2026

Regulatory updates effective from 1 January 2026 have been widely discussed around clearer time limits and process expectations (including how VAT audit time limits are governed by the Tax Procedures Law rather than older VAT-law language).

The 7 areas that trigger VAT audit issues

1. Incorrect tax invoices (missing TRN, wrong date/supply details)

2. Input VAT claimed without evidence (no valid invoice, no proof of business purpose)

3. Reverse charge mistakes (imported services, cross-border transactions)

4. Refund claims without support (exports, zero-rating evidence, customs docs)

5. Bad reconciliations (VAT return doesn’t match accounting system)

6. Credit notes & adjustments not properly linked to original supplies

7. Late registration / threshold monitoring (common with fast-growing SMEs)

• VAT Returns + working papers

• Sales invoices (with sequence)

• Purchase invoices (with approval trail)

• Customs/Import docs

• Zero-rated / exempt support

• Refund claim support (if any)
