How can I get a list of customers Sales tax registration which is needed for VAT returns where Reverse Charge mechanism operates?

You can keep track of those registration numbers for your VAT reporting by adding the customer's sales tax registration to the Other and VAT number boxes in your customer's profile. Once done, generate a Customer Contact List from the reports menu.

To display the tax details you need, customise the report by adding another Column. Choose the Additional contact info option to pull that specific field into your view.
