If your clinic is VAT registered, set that once under Business details. New services, products, and custom lines then default with VAT on — you can still override tax on individual products.
Turn on VAT for the clinic
- Go to Settings → Business.
- Scroll to Business details.
- Enter your VAT number (for example GB123456789).
- Turn on VAT registered if your clinic is registered.
- Click Save settings (or Save changes) at the bottom of the page.

Note
If a VAT number is set, new catalogue items default VAT on. On retail products you can still choose N/A or VAT at 20%, and whether the price includes tax.
