Hello @mohamedali850

Our default tax rate calculation feature in Bagisto should be able to fulfill your requirement, as it also provides an option to define tax rates based on zip codes.

Kindly refer to the following documentation for more details:
https://docs.bagisto.com/settings/taxes.html

However, if you need to implement a separate tax logic or integrate tax calculation via any external API, that will require custom development and implementation from our side.

Regards
