Hi @gautamrast ,
This can be done by enabling the option to include tax in your product prices:
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.
