Many people asked if there is a tool which can do bulk import tax table since tax table could be hundreds of tax regions. We have implemented the bulk tax import feature in the next version.
In Site Admin -> Store -> Tax, you will see the "Import Tax Regions" button.
After clicking the button you will see this.
You can point it to a text format tax file to import the tax regions defined in the tax file. Check
online document for the format of the tax file.
For people want to use this feature now, you could download from
here. And then copy the files to the web directory that your store was installed to.
