Upper Tribunal confirms clear aligners are standard rated for VAT
The Upper Tribunal has ruled that Invisalign clear aligners are not dental prostheses for VAT purposes, and that supplies of them are therefore chargeable to VAT at the standard rate rather than exempt. Published 7 July 2026, this decision overturns an earlier First-tier Tribunal ruling that had found in favour of Align Technology.
While the case may only concern one product, the Tribunal’s new definition has implications across the dental sector. For dental practices, laboratories and orthodontic businesses, it raises questions about both the treatment of future supplies and the position on periods already filed.
What did the Tribunal decide?
The exemption in question sits in Group 7 of Schedule 9 to the Value Added Tax Act 1994, and covers the supply of dental prostheses by dentists, dental care professionals and dental technicians.
The dispute was the inevitable result of the legislation missing a definition of dental prosthesis, which the Upper Tribunal has now provided.
The definition: The Tribunal defined dental prostheses strictly as artificial items which replace missing or damaged teeth, for example dentures, crowns and bridges.
The distinction: It determined that orthodontic devices that merely move or reposition teeth do not serve a prosthetic function and therefore do not qualify for the medical VAT exemption.
How will this impact dental businesses?
One of the more significant consequences of the decision is that income streams previously treated as exempt may now need to be reclassified as taxable.
In practice, the position is rarely clear cut, and the outcome of the VAT treatment is based on the reasoning for the treatment. Where an aligner is supplied as part of a wider course of treatment, careful thought is needed to determine whether it forms a single composite supply with the exempt treatment, or a separate taxable supply in its own right.
This would mean an increase in taxable turnover for VAT purposes where practices provide this service, but it will potentially have wider implications.
Taxable supplies count towards the VAT registration limit, so for dental practices already operating close to the threshold, this change may bring them into the scope of VAT registration, bringing an additional administrative burden along with the associated costs.
Where VAT registration is required, practices will also need to consider the partial exemption rules. Because input VAT on costs must be split between taxable and exempt activities, particularly where dental practices continue to make both types of supplies, the rules add another layer of complexity.
As a result, some VAT incurred on costs may be irrecoverable, increasing the overall cost of running the practice. Aligners themselves now carry VAT at 20%, and for cases already in progress on fixed fees there is no ability to reprice, so the immediate margin effect falls on work already committed.
Could this extend to other appliances?
The Tribunal drew a clear line between items that replace part of the body and items that support, correct or assist it. Retainers, braces and comparable orthodontic appliances sit on the same side of that line as aligners, so practices should expect the same standard rated treatment to apply to them. More broadly, any supply whose exempt treatment relies on a wide reading of the word prosthesis now looks harder to defend, and VAT positions set against an older product range may no longer hold.
What’s not changing?
The Upper Tribunal decision does not change the long-established VAT exemption for the provision of medical care by registered dental professionals.
For VAT purposes, medical care generally means treatment whose principal purpose is the protection, maintenance or restoration of a patient’s health. The exemption therefore continues to apply where:
- The treatment is provided by an appropriately qualified and registered dental professional.
- The principal purpose of that treatment is the protection, maintenance or restoration of the patient’s health.
Crowns, bridges and dentures may still qualify for the dental prostheses exemption, provided the item supplied and the status of the supplier meet the relevant conditions.
Our view
Holly Gibson, Price Bailey’s Healthcare Partner, comments:
“Whilst this decision concerns clear aligners rather than cosmetic dentistry as a whole, it forms part of a wider trend of increased scrutiny around the scope of healthcare VAT exemptions.
Historically, many dental businesses have operated within a framework where much of their activity has benefited from VAT exemption. However, HMRC is increasingly examining where the line should be drawn between health-related treatment and services that are primarily cosmetic in nature.
As the sector continues to innovate, businesses should expect greater focus on whether long established VAT treatments remain appropriate.”
