Hi Robert,

Are you referring to showing the price inclusive of GST on the ProductList or ProductDetail page? or on the Cart page?

If you want GST to show the price with tax inclusive on the Cart page, select VAT/GST in the Tax Setup section of the Cart Settings. A “Tax Type” dropdown list will be displayed that allows you to select VAT or GST. When VAT/GST Tax is checked the cart will charge the tax rate entered in the “Tax Rate” textbox and implement the VAT/GST tax calculation. You will need to load all
product pricing inclusive of VAT/GST tax.

Thanks
