Opening this thread here for any possible solutions, and also to warn other Canadians using Webflow Ecommerce. The current limitations of TaxJar (the service Webflow uses for tax calculation) and Webflow Ecommerce mean we cannot charge the correct tax rates for some items in some provinces.
I have confirmed this with Webflow Support and received the following reply after going back and forth:
Currently, the product tax class settings only apply for states in the US and some EU countries.
All products will have a 12% tax applied. 5% for GST and 7% for PST.
This is specific to BC - but the same applies to other provinces multiple types of sales tax. There is currently no option to only apply 5% GST. This means Canadians selling clothing or food (and some other categories) in certain provinces like BC cannot use Webflow Ecommerce.
Webflow Support says adding custom tax rates (when automatic is disabled) is on the roadmap for Q2 2020… but not guaranteed.
This is very disappointing - custom tax rates seems like a basic feature – I wonder why they chose to have TaxJar be the only option. I wish they were more clear about this when I first inquired, before setting up my client’s store using Webflow Ecommerce.
