When your business makes sales, you don't charge VAT to your customers unless you're registered with HMRC to do so. Sales on which VAT would normally be charged are called “taxable sales”. Sales that are exempt from VAT, or outside the scope of UK VAT, are not taxable sales.
Just so, do I have to charge VAT to overseas customers?
VAT on exports to non- EU countries. VAT is a tax on goods used in the EU , so if goods are exported outside the EU , you do not charge VAT. You can zero rate the sale, as long as you get and keep evidence of the export, and comply with all other laws. send the goods to your customer.
Do you charge VAT to the US?
Exporting goods to the USA. Most goods exported to the States can be zero-rated for UK VAT purposes (that is, VAT does not need to be added), as long as documentary evidence of the export is kept. Any extra charges made for freight, shipping, postage or delivery are also zero-rated.
