From 1 January 2026, the UAE’s VAT landscape will undergo important changes designed to simplify compliance, reduce administrative burden, and increase transparency for businesses of all sizes. Amendments under Federal Decree-Law No. (16) of 2025 will reshape how reverse charge transactions are documented, how long businesses can claim VAT refunds, and how the Federal Tax Authority (FTA) treats input VAT linked to fraudulent activities. These changes make VAT processes clearer but also place greater responsibility on businesses to maintain strong documentation, internal controls, and tax governance.

Key VAT Changes Effective January 2026

The new rules focus on three main areas: documentation for reverse charge transactions, time limits for VAT refunds, and the treatment of input VAT linked to fraud or abusive schemes.

1. Removal of Self-Invoicing for Reverse Charge Transactions

Under the current regime, businesses often issue self-invoices for reverse charge transactions to document VAT on supplies received from abroad or from unregistered suppliers. From January 2026, this requirement will be removed.

Instead, businesses will be required to:

  • retain supplier invoices, contracts, and related documentation,
  • ensure their accounting systems clearly reflect reverse charge entries,
  • maintain records in a format that supports FTA audits and reconciliations.

This change reduces duplication of paperwork and aligns UAE practices more closely with international VAT standards. However, the burden shifts towards maintaining robust underlying documentation and accurate accounting treatment.

2. Five-Year Deadline for Claiming Refundable VAT

From 2026, a firm five-year time limit will apply to claiming refundable VAT. Businesses will no longer be able to carry unresolved or unclaimed input VAT indefinitely.

In practice, this means businesses must:

  • reconcile VAT accounts on a regular basis,
  • identify recoverable VAT promptly,
  • submit refund claims within the five-year window,
  • ensure supporting records are complete and audit-ready.

This rule is designed to prevent long-outstanding input VAT balances and provide more certainty to both taxpayers and the FTA. For businesses, it increases the importance of timely reconciliations and structured VAT processes.

3. Stricter Treatment of VAT Linked to Fraudulent Supplies

The amendments give the FTA explicit authority to deny input VAT deductions where the underlying transactions are connected to fraudulent or abusive schemes. This aligns the UAE VAT regime more closely with international approaches that link the right to deduct input tax with the legitimacy of the supply chain.

Businesses will be expected to:

  • apply basic due diligence when selecting suppliers,
  • verify the legitimacy of transactions,
  • retain documentation demonstrating that they acted in good faith,
  • strengthen internal controls around high-risk transactions.

If the FTA determines that a business knew or should reasonably have known that it was involved in fraudulent structures, input VAT may be denied—even if the invoice appears correct on its face.

What These Changes Mean for UAE Businesses

While the overall aim of the amendments is simplification and fairness, they also require businesses to tighten their VAT processes, documentation, and compliance culture.

Greater Emphasis on Documentation & Controls

With self-invoicing removed, businesses must ensure that supplier invoices and contracts are properly collected, reviewed, and stored. Accounting entries must clearly show how reverse charge VAT was applied and reported.

More Structured VAT Reconciliation Processes

The five-year deadline for VAT refunds means businesses should:

  • implement regular VAT reconciliation cycles (monthly or quarterly),
  • track outstanding input VAT that has not yet been claimed,
  • resolve discrepancies quickly to avoid missing the claim window.

Enhanced Supply Chain Due Diligence

The FTA’s increased authority to deny input VAT in cases of fraud makes supplier risk assessment more important. Businesses should:

  • verify supplier tax registration where applicable,
  • be cautious of unusually low prices or unclear transaction terms,
  • ensure contracts and commercial logic align with the invoices issued.

This is particularly important for sectors with complex supply chains or high volumes of cross-border transactions.

Practical Steps to Prepare Before January 2026

To get ready for the new VAT rules, businesses should start reviewing and upgrading their tax processes well before the effective date.

1. Review Current VAT Workflows

Businesses should map how VAT is currently handled—from invoice receipt and booking to return preparation and refund claims. This will help identify gaps that could cause issues under the new regime.

2. Update Accounting & ERP Systems

Systems should be configured to:

  • correctly record reverse charge VAT without self-invoicing,
  • tag and track input VAT balances and refund eligibility periods,
  • generate reports required for FTA audits.

3. Strengthen Documentation Practices

Companies should put in place clear policies for:

  • retaining supplier invoices, contracts, and proof of supply,
  • organising VAT-related documentation for easy retrieval,
  • storing data in line with FTA record-keeping requirements.

4. Introduce Supplier Due Diligence Checks

Implement basic checks on key suppliers, such as:

  • valid trade license and tax registration (where required),
  • reasonable commercial terms,
  • clear evidence that goods or services were actually supplied.

These controls help demonstrate that your business took reasonable care, reducing the risk of denied input VAT.

5. Train Finance & Tax Teams

Internal teams should be briefed on:

  • the removal of self-invoicing and new documentation standards,
  • the five-year limit on refundable VAT,
  • the risks associated with fraudulent or artificial transactions.

Well-informed staff are critical to maintaining ongoing compliance.
