Taxes will now be calculated for merchants using our Duties and Import Taxes calculator, in countries they configured to not collect duties and have a tax registration.
Previously, when merchants turned on the Duties and Import Taxes calculator, sales tax would not be calculated if the merchant did not configure duty collection in a country. This effectively ignored the tax registrations of a merchant for that country.
If you do not want sales tax to be calculated on international orders when you do not collect duties, you should remove your tax registration in the given country.
