Most VAT penalties don't come from fraud — they come from small, repeatable mistakes in how input tax is claimed and returns are reconciled. Here are the five we see most often, with the exact rules behind each one.
After reviewing VAT filings across retail, construction and services businesses, a pattern emerges: penalties rarely come from deliberate underreporting. They come from a handful of recurring, avoidable mistakes rooted in how Federal Decree-Law No. 8 of 2017 and its Executive Regulations (Cabinet Decision No. 52 of 2017, as amended) actually treat specific categories of input tax and specific types of supplies.
1. Claiming Input Tax on Non-Recoverable Expenses
Article 53 of the Executive Regulations specifically blocks input tax recovery on entertainment services provided to anyone other than employees (clients, shareholders, officials), on goods or services given to employees free of charge (unless there's a legal obligation under UAE labour law or a documented contractual policy obligation to provide them), and on motor vehicles available for personal use — road vehicles designed to carry ten people or fewer, whether purchased, rented or leased, with an exception for licensed taxis and rental-fleet vehicles. A November 2024 amendment to the Executive Regulations expanded what counts as recoverable for employee health insurance, including cover for a spouse and up to three children under 18, but the general entertainment and personal-vehicle exclusions remain firm.
A logistics company leased three passenger vehicles for its sales team to use for both client visits and personal errands, and claimed the input VAT on the lease payments. Because the vehicles were available for the employees' personal use, that input tax was never recoverable — the correct treatment would have been to either restrict the vehicles to business-only use with a documented policy, or exclude the input tax from the claim entirely. This is one of the most common findings in FTA audits.
2. Missing the Reverse-Charge Mechanism
When importing services (or certain goods) from outside the UAE, VAT-registered businesses must self-account for VAT under the reverse-charge mechanism, declaring both the output VAT and — where recoverable — the corresponding input VAT in the same return. This is easy to miss because the transaction never generates a UAE tax invoice. Note that Federal Decree-Law No. 16 of 2025, effective 1 January 2026, removed the requirement to issue a self-invoice for reverse-charge imports under Article 48 — but the underlying obligation to self-account for the VAT itself in your return has not changed, only the invoicing formality around it.
3. Filing Nil Returns Incorrectly
A period with no standard-rated sales isn't necessarily a nil return — zero-rated exports and exempt supplies still need to be reported in the correct boxes, and skipping them creates a mismatch between your VAT returns and your accounting records that an auditor will flag immediately, even though no tax was actually due on those supplies.
4. Late Credit Note Adjustments
Credit notes issued after the original tax period must be reflected in the period they legally relate to, following the specific adjustment mechanics in the VAT law, not simply netted off against the current period's output tax figures. Getting the timing wrong changes which period's return is technically inaccurate.
5. Reconciliation Gaps Between VAT Returns and Accounts
When VAT filings and the general ledger drift apart over several periods, it becomes one of the first things an FTA auditor checks — even if every individual return was filed on time and the tax paid was broadly correct. Since Federal Decree-Law No. 16 of 2025, unused recoverable input tax can now only be carried forward for 5 years from the end of the tax period in which it first arose (under the amended Article 74(3)) before the right to claim it lapses entirely, which makes clean, current reconciliation more important than ever.
Filing Frequency and Deadlines
VAT returns are due within 28 days of the end of your tax period. The FTA assigns your filing frequency at registration: broadly, quarterly for businesses with annual turnover below AED 150 million, and monthly for businesses at or above that threshold, though the FTA can assign a different period at its discretion.
The Fix
A periodic VAT health check — reconciling filed returns against your accounting records and re-testing input tax claims against Article 53 — catches these issues long before an audit does. It's a standard part of how we manage VAT return filing for clients.
