Maybe this will help you move forward.
Yes, creating a new environment in the correct region (e.g., U.S. for Sales Tax vs. EU for VAT) is the right approach, since localization is region-based and can’t be fully changed after environment setup.
To move company data:
1. Export Data:
Use Configuration Packages (RapidStart) to export master data (customers, items, vendors, etc.).
For transactional data, consider exporting journal entries or using data export extensions.
2. Set Up New Environment:
In the correct region (e.g., U.S.), create a new sandbox or production environment from the Admin Center.
3. Import Data:
Recreate the company structure.
Use the same configuration packages to import the data into the new environment.
4. Test Tax Setup:
Configure Sales Tax (not VAT) using U.S. localization.
Verify correct tax groups, jurisdictions, and codes.
