I want to display the catalog price including tax only for UAE visitors. I know this is achievable using multi store. We don't want to have a multi store as we're using Algolia search and it will be doubled the cost of Algolia.
How can I achieve this without having multi-store?
For displaying tax to the specific product pages and category product list page these can be managed from the following tax display settings given on configuration. Please adjust the display as per your need. If you want that any specific country just needs to show the tax then you can extend the specific price.phtml file and give certain conditions to run as per your needs.
