Magento 2 | Display Catalog prices for specific groups without Tax

Question

I'm currently experiencing a weird problem on my Magento 2.2.6 Store. While giving some customer-groups a 0% Tax Rule the prices on the catalog get still displayed with tax, even tho the "tax info text" says its 0%. Am I missing a configuration or do I miss configure something? Cross-Border Trade setting is "off"

I've attached 2 images to visualize the problem a bit better. The first picture shows the price without tax inside the shopping cart ( thats how it is supposed to be ). The second image shows the product at the catalog ( including tax ).

I had the idea that it was probably an issue from my custom theme but after checking that in comparison with the default Luma Theme I can confirm that this issue still exists.

I thought I had an issue in my taxrules but that look correct for me, i'll attach an image of the configurations below:

As wished I upload the Rates.csv for you guys to take a look at it:

Basically all 0% Tax-rates are assigned to the "tax free" Customer groups.

Answer 1

There is a configuration for showing catalog prices with or without tax, you should set it to Excluding Tax

Admin=>Store=>Settings=>Configuration=>Sales=>Tax=>Price Display Settings=>Display Product Prices In Catalog

If you got that config correct and it's still showing with the taxes then you might have something else going on in your templates.

Answer 2

If the customer group is added the tax rule, just don't have a tax rule for that customer group.

If there is multiple rules ensure the customer group is not on there.

Not having tax is the same as trying to set the tax to 0.

That should exclude them. For the main tax rule , you might have to manually select what is needed as it can choose all by default.
