VAT Input Denial and Tax Evasion
Under Federal Decree-Law No. 16 of 2025, the FTA must deny your input VAT recovery where a supply or its chain is connected to tax evasion you knew or should have known about. It may also deny recovery where a transaction lacks commercial substance or is a tax-avoidance arrangement. From 1 January 2026 this makes supplier due diligence a VAT control: know your counterparty, keep evidence the supply is real, and price at arm's length.

Input VAT can fail because of the supply chain behind it
Federal Decree-Law No. 16 of 2025 added Article 54 bis to the UAE VAT Law. The Federal Tax Authority must reject recoverable input tax when the supply, or a chain of supplies, is related to tax evasion and the taxable person knew that relation when deducting the tax. A valid invoice is still required, but it cannot rescue a transaction that the surrounding facts do not support.
The same article gives the FTA discretion to reject the deduction when the business should have been aware of the connection. Article 54 bis says a taxable person is considered required to be aware if it did not verify the validity and integrity of received supplies using the measures, procedures and conditions set by the Authority. The distinction is must reject versus may reject.
The practical answer is a transaction file that explains the purchase before the return is filed. Check the counterparty, contract, delivery or performance, payment and business purpose. Where those objects do not agree, hold the input line for review. Do not let a clean invoice list decide a question that belongs to the evidence file.
- Article 54 bis creates a mandatory denial case.
- A second case lets the FTA deny on the surrounding facts.
- Verification before deduction is now a stated control.
- The invoice is one object in a wider file.
| Finding | Legal position | Control response |
|---|---|---|
| Evasion link and business was aware | FTA must reject the deduction | Hold the input tax and escalate |
| Evasion link and business should have known | FTA may reject the deduction | Review the missing verification |
| Supply file supports the transaction | Normal recovery rules apply | Retain the connected evidence |
| Evidence gap is unresolved | Position is not ready to sign | Record, correct or isolate the line |
The risk sits with unusual purchases, not every supplier
The rule matters most where a business buys through an unfamiliar chain, claims a large input amount or cannot explain the commercial role of a counterparty. A new supplier is not automatically a problem. A price difference is not proof of evasion. The point is to make the purchasing file answer why this supplier was chosen, what was received and how the amount reached the ledger.
A business cannot document facts that were hidden from it, but it can respond to facts in front of its staff. A delivery note that does not match the invoice, a contract that describes a different service, a payment to another entity or a supplier with no credible operating record should prompt a question. The answer belongs beside the transaction, not in a general supplier policy.
The mistake we see most is treating a TRN check as the whole due-diligence exercise. It confirms an identity detail. It does not prove that the service was performed, the goods arrived, the price made commercial sense or the payment went to the contracting supplier. Article 54 bis turns those surrounding facts into a VAT control when input tax is deducted.
- Start with unfamiliar or high-value suppliers.
- Separate a warning sign from a conclusion.
- Record the business reason for the purchase.
- Do not treat the TRN as the whole file.
Build evidence around what was delivered and paid
For a goods purchase, keep the contract or purchase order, supplier invoice, delivery note, warehouse or acceptance record, payment proof and supplier TRN check. Add customs and shipping records for imports. For a service, keep the engagement terms, work product, completion evidence, correspondence and approval. Each object should identify the same supplier, amount and business purpose.
The amount needs an explanation too. A quotation, approval note or comparable offer can show why the purchase was accepted. It does not need to prove that the business selected the cheapest option. It needs to show that the counterparty was identified, the supply was real and the payment followed a traceable approval. A large input claim without that chain is a weak claim even when the invoice looks perfect.
The client should provide the ledger extract, source documents, payment records, contracts and any customs file for the transactions selected. The review should return an exception list naming the invoice, missing object, owner and action. It should not promise that a checklist creates a safe result. The facts of the supply still decide the recovery position.
- Supplier identity and TRN check.
- Contract, order and tax invoice.
- Delivery, work product and payment proof.
- Approval note for unusual value or routing.
Review the largest or least familiar lines first
Start with the VAT return working and rank the input lines by value, supplier familiarity and unusual features. Select the transactions that would hurt most if the input tax were held out. Trace each line from the ledger to the invoice, contract, delivery or work product, payment and business use. Write down the source object when a link is missing.
Next, compare the story across the documents. Does the supplier named in the contract receive the payment? Does the invoice describe the work that was accepted? Do the quantities, dates and delivery records agree? If the answer is no, ask the purchaser for the reason and retain the response. A real explanation can close a gap. Silence cannot.
Finish with a dated exception list before the return is approved. State whether each line was corrected, supported, held out or escalated. Do not bury unresolved entries in a general sentence that suppliers were checked. A reviewer needs the invoice number, amount, missing evidence and decision. That is the record that prevents the same gap returning next period.
- Rank by value and visible warning signs.
- Trace each return line to its source.
- Record the purchaser's explanation.
- Isolate unresolved input before sign-off.
The unsupported amount is a cash exposure
Worked example, not a statutory amount: the ledger shows AED 48,000 of input VAT, while invoices and customs records support AED 41,600. The unsupported gap is AED 6,400, calculated as AED 48,000 - AED 41,600 = AED 6,400. The reviewer should identify the entries behind that gap, correct the period or evidence, and then decide what amount belongs in the return.
If the AED 6,400 cannot be supported, it is not a harmless rounding difference. It is input tax the business may have to leave out or defend in an FTA review. That makes the cost of weak evidence visible before the return is filed. Do not invent a denial percentage or an automatic penalty from this example. The law gives the FTA a denial power, not a formula for every file.
The official law sets the phrase should have been aware but does not give a universal safe-harbour list for every supply chain. Its application to a particular set of facts remains unsettled. We would document the verification performed and the reason for the purchase, then seek a tax view where the chain cannot be explained from the business records.
- The example gap is AED 6,400.
- A denied input amount becomes a direct cash cost.
- The law does not set one safe-harbour checklist.
- Facts and documents decide the risk.
Frequently Asked Questions
For protecting your input recovery.
When must the FTA deny input VAT?
Where a supply or the chain behind it is connected to tax evasion that you knew or should have known about. This is mandatory, not discretionary, so a reasonable business is expected to have spotted an obvious problem.
What does the FTA have discretion to deny?
The FTA may deny input recovery where a transaction lacks commercial substance or forms part of a tax-avoidance arrangement. This is assessed on the facts, and artificial or purely tax-driven structures are the target.
What does knew or should have known mean?
It sets an objective standard. You cannot rely on not knowing if a reasonable business in your position would have questioned the supply, the price, or the counterparty. Documented due diligence is your protection.
How do I protect my input VAT?
Validate each supplier's TRN, keep the contract and proof of delivery, show the price is at arm's length, and record why the transaction makes commercial sense. Long or unfamiliar supply chains deserve extra checks.
Who is most at risk?
Businesses reclaiming large input credits through unfamiliar or multi-layered supply chains with thin paperwork. That profile is exactly where a denial under these rules can turn a neutral transaction into a real cost.
Can Exiloz protect our recovery position?
Yes. We build the supplier due-diligence trail that keeps your input VAT recovery standing up to FTA scrutiny and flag the transactions most exposed to denial.
