Call [Tax Calculation Integration Service Plugin](https://dev.wix.com/docs/api-reference/business-solutions/e-commerce/extensions/tax/tax-calculation-integration-service-plugin/introduction.md) to calculate tax, or, in [Tax Settings in the Wix dashboard](https://www.wix.com/my-account/site-selector/?buttonText=Select%20Site&title=Select%20a%20Site&autoSelectOnSingleSite=true&actionUrl=https:%2F%2Fwww.wix.com%2Fdashboard%2F%7B%7BmetaSiteId%7D%7D%2Fecom-platform/tax/), select the new region and set the tax rate to apply for all existing tax groups.
