The new tax rules, effective from January 2026, introduce major procedural and compliance changes across VAT, corporate tax, and federal tax systems. These updates strengthen enforcement, define clear timelines, and improve transparency in tax administration.
a. Five-Year Deadline for VAT Refunds and Tax Credits
The UAE has introduced a strict five-year deadline for claiming VAT refunds and using tax credit balances. Under the updated UAE VAT law, businesses can carry forward excess recoverable VAT for only five years from the end of the relevant tax period.
If a business does not use the credit or submit a refund request within this period, the right to recover that amount expires permanently. Previously, businesses could carry forward VAT credits indefinitely, which often resulted in large unclaimed balances.
This change requires businesses to adopt a proactive approach toward VAT management and financial planning.
What this means for businesses:
- Review all existing VAT credit balances without delay.
- Identify the relevant tax period for each credit entry.
- Submit refund claims or adjust liabilities before the five-year deadline expires.
This limitation rule also applies to other federal tax credits, including corporate tax and excise tax.
b. Stronger and Extended Audit Powers for the FTA
The FTA UAE now holds significantly stronger audit authority under the new Tax Procedures Law. Audit and assessment periods can now extend up to fifteen (15) years in certain cases, such as cases involving tax evasion or failure to register for tax purposes. Previously, the standard limit was five years.
This does not mean every business faces a 15-year audit window. The standard five-year limit still applies in normal cases. But if the FTA finds evidence of deliberate evasion, non-registration, or fraud, it can investigate up to 15 years into the past. This change makes it riskier than ever to ignore tax registration or manipulate filings.
c. Easier Correction of Tax Errors Through Voluntary Disclosure
The new tax rule in the UAE introduces flexibility for correcting errors through an improved voluntary disclosure framework. The FTA now allows businesses more flexibility to submit Voluntary Disclosures (VDs) to correct non-material errors without facing full penalties.
Taxpayers may submit a Voluntary Disclosure within two years of filing a refund request, provided the FTA has not issued a decision. This provision gives businesses additional time to review past filings and correct any identified errors.
This is particularly useful for businesses that had old, unresolved refund claims from before January 2026. They receive a one-year transitional window to file those historic refund requests and can then correct related errors within two more years if needed. This change benefits businesses that made genuine mistakes in earlier filings and want to correct them responsibly.
d. Removal of Self-Invoicing Requirement Under Reverse Charge VAT
The UAE’s new tax rules simplify compliance by removing the requirement for self-invoicing under the reverse charge mechanism. Under the earlier UAE VAT law, businesses importing goods or services for business use had to issue a self-generated tax invoice to record VAT liability.
From 1 January 2026, businesses no longer need to issue such self-invoices for reverse charge transactions. Instead, they must maintain original supplier invoices, contracts, customs declarations, and other relevant supporting documents.
This change reduces unnecessary duplication of records while maintaining a proper audit trail for verification purposes. Authorities now place greater emphasis on the quality and accuracy of supporting documentation during audits.
Businesses that frequently handle imports or cross-border transactions will benefit from reduced administrative effort and improved operational efficiency. However, they must ensure proper record-keeping to remain compliant with UAE VAT law and Federal Tax Authority requirements.
e. Stronger Anti-Evasion Rules — The “Should Have Known” Principle
The updated framework introduces stricter anti-evasion provisions that directly affect input VAT recovery. The Federal Tax Authority may deny input VAT claims if a transaction links to tax evasion and the taxpayer knew or reasonably should have known about it.
Before this change, a buyer could recover input VAT as long as they held a valid tax invoice, even if the supplier had committed VAT violations. Now, if your supplier was involved in a fraudulent VAT arrangement and you reasonably should have known about it, the FTA can deny your input VAT claim.
Businesses must now conduct proper due diligence before claiming input VAT. They must verify supplier registration, confirm the legitimacy of transactions, and ensure accurate tax treatment. Failure to perform these checks may result in disallowed claims and financial exposure.
f. FTA Can Issue Binding Directions for Consistent Tax Interpretation
The amended law authorizes the Federal Tax Authority to issue binding directions for consistent interpretation of tax provisions. These directions guide how businesses must apply tax rules across different transactions and compliance scenarios.
This development reduces ambiguity and limits conflicting interpretations across industries. Businesses must follow these directions when applying tax provisions to ensure compliance with regulatory expectations.
As a result, the updated framework creates a more predictable compliance environment and supports uniform application of tax rules across all sectors.
