I want to display the product prices with tax in the collections itself. I want to do this so that when customer checksout the final amount payable by customer does not increase with tax but rather shows a separate line item that tax $123 amt of tax was already included in the price of the item.
Enabling this option in Settings > Taxes and duties means all prices you input will be deemed as tax-inclusive by Shopify's tax system. Your customers will still see a breakdown of the taxes they are paying at checkout and in their order confirmation, but these taxes will not be added on at the checkout page.
I hope this helps but please let me know if you have questions.
