UAE VAT Amendments 2026: Critical Input Tax Checks, Refund Cutoffs, and Supplier Risk Controls for Abu Dhabi

The most material shift for many recipients of goods and services is input tax scrutiny. Businesses are now expected to apply a “reasonable level of scrutiny” to the VAT treatment adopted by their suppliers and to recognize situations where the supplier may be involved in tax evasion. If a business fails to question or verify VAT treatment where it reasonably should have been challenged, input VAT recovery may be denied even where VAT was charged and paid to the supplier. Other commentary frames this as a due diligence obligation: accepting VAT invoices at face value is no longer sufficient. For higher-value purchases, that can translate into confirming the supplier’s VAT registration status, checking whether the invoice treatment makes sense, and documenting that verification.

Refund Deadlines and the End of Indefinite Carry-Forward

Refund management is another area where Abu Dhabi businesses will need tighter controls. Under the previous rules, excess input VAT that was not refunded could be carried forward indefinitely to future tax periods, but from 1 January 2026 this will no longer be possible. A strict five-year time limit applies for claiming excess refundable VAT from the end of the relevant tax period, and balances beyond that period will expire and become non-refundable. That creates a practical tracking requirement: businesses must track VAT credits by originating tax period and ensure refund applications are submitted, or credits are used to offset VAT liabilities, before the relevant five-year deadline. Guidance also flags that VAT credits arising in 2021 should be reviewed as a priority because those balances will begin to lapse during 2026 if no action is taken.

Transitional relief adds a specific action date for older credits. Summaries of the amendments state that businesses can submit refund claims for older VAT credits by 31 December 2026 before those credits expire, and guidance highlights this transitional deadline in readiness checklists. Practical advice for Abu Dhabi operators is to pull VAT records by tax period, identify credit balances from 2020 or 2021, calculate when each five-year window closes, and then choose between filing a refund application or using the balance to offset current liabilities. Commentary also warns that last-minute refund claims can carry higher risk, because timing near a deadline may invite deeper review than an earlier, well-supported filing.

The amendments also adjust reverse charge administration by removing the requirement to issue self-invoices for reverse charge transactions. Instead, businesses should retain supplier-issued invoices and relevant import documentation as evidence. This is framed as a simplification that reduces redundant documentation while keeping audit transparency through conventional records. For Abu Dhabi businesses, the operational lesson is to stop generating self-invoices out of habit and build an evidence pack approach: supplier invoice, import documentation where relevant, and any supporting contracts or records specified in the Executive Regulations. Combined with stronger supplier vetting, this documentation discipline supports both input tax recovery and faster responses if the Federal Tax Authority challenges a claim tied to higher-risk transactions.
