UAE mandates VAT supplier and supply verification checks: what every registered business must now do
The UAE has introduced compulsory VAT verification checks on suppliers and supplies, tightening compliance obligations for all registered businesses.
# The rule change in plain terms
The UAE Federal Tax Authority has introduced mandatory verification checks on VAT suppliers and supplies. Registered businesses are now required to confirm that the suppliers they deal with are themselves properly VAT-registered and that the supplies being claimed as input tax credits are genuine and correctly categorised, before those credits are reclaimed. The obligation sits with the buyer, not only the seller.
Khaleej Times reported the change on 20 August 2026.
# Who this affects and why the stakes are high
Any business that files VAT returns in the UAE and claims input tax recovery is inside the scope of this change. That covers a broad population: trading companies, service firms, manufacturers and professional practices alike. The verification requirement is procedural, but the financial consequences of getting it wrong are not.
If a business claims input tax credit on a supply from an unregistered or incorrectly registered counterparty, the FTA can disallow the deduction. In the worst cases, penalties apply. The burden of proof now rests explicitly on the claiming business to show it carried out adequate checks before filing.
For companies operating at volume, with dozens or hundreds of supplier invoices processed each month, a manual approach to verification is neither practical nor reliable. The FTA's online TRN (Tax Registration Number) verification portal remains the primary tool, but the new rules appear to formalise the expectation that this check is conducted systematically, not occasionally.
# Where existing compliance processes fall short
Many businesses registered for VAT in 2018 built their controls around the original filing framework: collect invoices, match purchase orders, reconcile with bank records, file quarterly. Supplier verification was often treated as a one-time onboarding exercise rather than an ongoing obligation.
That approach is now inadequate on two counts. First, suppliers can lose their VAT registration status, including through deregistration following non-compliance on their own part. A supplier that was validly registered when first onboarded may not be registered at the point of a specific transaction. Second, the nature of a supply can change: a product or service that qualified for input tax recovery in one context may not in another if circumstances or usage shift.
The practical implication is that verification needs to be embedded in the procurement and accounts-payable cycle, not treated as a background administrative task.
# What to do about it
Audit the current supplier list. Run every active supplier's TRN through the FTA verification portal now, before the next filing period. Document the results with timestamps. Any supplier whose TRN fails verification should be quarantined from input tax claims until status is confirmed.
Build verification into the purchase process. Any new supplier onboarding should require TRN verification as a mandatory step, with the output saved to the supplier file. For high-volume suppliers, set a periodic re-verification schedule (quarterly is a reasonable starting point).
Review pending VAT returns. If the current or most recent return includes input tax claims that were not subject to explicit supplier verification, consider reviewing those line items before submission or, if already filed, seek advice on whether an amendment or voluntary disclosure is appropriate.
Train accounts-payable staff. The people processing invoices need to understand what the check is, how to run it, and what to do if a supplier's registration cannot be confirmed. A short internal protocol document is worth preparing now.
Keep records. The FTA will expect businesses to demonstrate they carried out these checks if queried during an audit. A spreadsheet log, a system export or a saved screenshot are all defensible. Verbal confirmation is not.
Businesses that file returns soon should treat this as an immediate priority rather than a process improvement for the next quarter.
