UK Appeal to Revisit Whether Invisalign Aligners Are VAT-Exempt Dental Prostheses

Summary 

• Align Technology has received permission to appeal the Upper Tribunal decision on whether Invisalign aligners qualify as dental prostheses. 
• The Upper Tribunal held in July 2026 that aligners reposition existing teeth and do not replace missing or damaged teeth, so they fall outside the prosthesis exemption. 
• No Court of Appeal hearing date was identified in the available source; the Upper Tribunal outcome remains the operative reported decision pending appeal. 

Extended article 

The First-tier Tribunal had accepted that aligners could fall within the exemption in items 2 and 2A of Group 7, Schedule 9 VATA 1994. The Upper Tribunal reversed that decision, interpreting “dental prostheses” as artificial items replacing missing or damaged teeth. 

The appeal matters for manufacturers, dental technicians and practices because it addresses the VAT treatment of the appliance itself. The separate exemption for clinical treatment by qualified professionals is not the same question.
