Contractor Withholding Your Tax Invoice? How UAE Courts Are Protecting Tax Refunds (Abu Dhabi Cassation Judgment No. 289 of 2026)

In the evolving legal landscape of the United Arab Emirates (UAE), the intersection between commercial construction disputes and tax compliance presents unique challenges for property owners. Often, contractors withhold essential documentation, particularly tax invoices, as leverage during payment disputes. However, these invoices are strictly required by the Federal Tax Authority (FTA) for taxpayers seeking Value Added Tax (VAT) refunds. A landmark ruling by the Abu Dhabi Court of Cassation in Judgment No. 289 of 2026 (Commercial), issued on April 14, 2026, provides a masterclass on how UAE courts utilize the civil doctrine of specific performance to mandate the delivery of tax invoices, empowering taxpayers to strictly comply with FTA regulations.

The Factual Matrix and The Court’s Ruling

The dispute in Judgment No. 289 of 2026 arose from a construction contract for a residential villa. The contractor (the Respondent) initiated a lawsuit against the project owner (the First Defendant), the financing bank (the Appellant), and the consultant.

The Court summarized the facts, noting that the contractor sought the remaining value of the project works and compensation after a breakdown in the relationship:

(“By virtue of a contracting contract dated 20/07/2020 for the construction, completion, and maintenance of a residential villa… against a lump sum of 2,000,000 dirhams… however, following the connection of electricity… the first defendant, the employer, took possession of the villa and lived in it, and prevented the respondent’s workers from entering the site to complete the remaining works and final finishes, in addition to retaining equipment, machinery, and cables belonging to the respondent inside the villa.”)

During the proceedings, an engineering expert was appointed. Crucially, the expert assessed not only the financial dues but also the documentation necessary for tax compliance. The Court of Cassation highlighted this vital finding:

(“The supervising judge appointed an engineering expert who deposited a report concluding that the remaining amount for the respondent is 360,577 dirhams… and that it is incumbent upon the contractor (the respondent) to deliver to the first defendant (the owner) the tax invoices in the amount of 85,577 dirhams so that he can recover the value-added tax.”)

Recognizing the statutory necessity of these documents, the Court applied the principle of specific performance, upholding the lower court’s ruling which strictly ordered:

(“Compelling the respondent to deliver to the first defendant (the owner) all invoices and documents related to the project…”)

The FTA’s Position on Holding Compliant Tax Invoices

The project owner’s demand for the tax invoices via a court order highlights the uncompromising administrative position of the Federal Tax Authority (FTA). Under UAE Federal Decree-Law No. 8 of 2017 on Value Added Tax, recovering input tax or claiming a refund, such as the special scheme for UAE Nationals building new residences under Article 61, is strictly conditional upon the taxpayer holding a valid, compliant tax invoice.

The FTA operates on strict documentary compliance. It mandates that a tax invoice must meet all rigorous requirements set out in Article 59 of the Executive Regulations (e.g., displaying the words “Tax Invoice,” the supplier’s Tax Registration Number, a description of the goods or services, and the exact tax amount). A mere bank transfer receipt, a payment certificate, a contract, or even a court-appointed expert’s report establishing that VAT was paid is legally insufficient for the FTA.

Because the FTA acts as a strict gatekeeper, withholding refunds if compliant invoices are absent, a contractor’s refusal to issue or hand over a tax invoice causes direct, quantifiable financial harm. In this case, the owner stood to lose 85,577 AED in VAT refunds solely due to the lack of compliant invoices. Consequently, taxpayers must rely on specific performance to force counterparties to produce these mandatory documents.

Legal Principles Applied by the Court

The judgment is rich in its application of procedural and substantive legal principles. Beyond specific performance, the Court of Cassation addressed Capacity or Legal Standing.

The financing bank appealed the judgment, arguing it lacked capacity as it was merely a funder:

(“That its role was limited to financing the project only, without there being any direct or indirect relationship with the respondent…”)

The Court decisively rejected this, laying out a foundational legal principle regarding capacity:

(“A lawsuit is the right to resort to the judiciary to protect a claimed right or legal position; hence, substantive capacity must exist for both parties… Capacity is met in the defendant if the right claimed in the lawsuit exists against him, considering him a concerned party and responsible for it if the plaintiff’s entitlement is proven.”)

Furthermore, the bank argued it could not disburse funds without the owner’s written instructions. The Court established the vital principle of Judicial Supremacy over Contractual Restraints, stating:

(“And that the judgment issued by the court to liquidate the account serves in place of the owner’s written instructions and supersedes them, rendering unnecessary the existence of written instructions from the owner to the appellant to disburse the respondent’s dues…”)

Conclusion

Abu Dhabi Court of Cassation Judgment No. 289 of 2026 serves as an essential precedent for taxpayers navigating the intersection of contract law and VAT compliance. By affirming the order for specific performance to hand over tax invoices, the court recognized the functional reality of UAE tax law: without the physical tax invoice, the statutory right to a VAT refund is nullified. This judgment safeguards taxpayers, ensuring that the withholding of tax documentation cannot be weaponized in commercial disputes.
